TECHNICAL FIELD

The present disclosure relates to the field of medical device technologies, more particularly, to a method and system for controlling a medical device.

BACKGROUND

Sickbeds refer to beds used by patients for convalescing, including common and multi-functional sickbeds. The sickbeds may also be referred to as medical beds, nursing beds, etc. The sickbeds are used by patients for convalescing, and are mainly used in occasions such as major hospitals, township health centers, community health service centers and families.

With the progress of society and the development of science and technology, most sickbeds currently used in hospitals are controlled by an intelligent control device. Movement, fixation and the like of the sickbed can be controlled by a CPAN on a rack and/or a CTBOX in an operation room, or controlled by a wireless terminal. In order to facilitate a doctor to operate a medical device to scan a patient, a mobile terminal communicatively connected to the medical device has been added to assist the scanning of the medical device. The doctor can use the mobile terminal to control a position of the sickbed, and then return to a console of the medical device to control the medical device to scan the patient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that particular embodiments described herein are intended only to interpret the present disclosure and not intended to limit the present disclosure.

With the rapid development of medical imaging devices (also known as medical devices), an increasing number of people choose to use such medical devices for preliminary detection when various functions of the human body are detected, and then next detection or treatment is performed according to a preliminary detection result. In a current working process of a medical device, firstly, a patient enters a scanning room from a patients' access door, and then follows a technician's instructions to lie on a sickbed; the technician holds a terminal, operates the terminal to control the sickbed to rise and advance, and positions a to-be-scanned site of the patient; then, the technician returns to the operation room from a technicians' access door with the terminal, and operates a control device to complete examination on the patient; finally, the technician enters the scanning room from the technicians' access door with the terminal, tells the patient to go down the sickbed, and waits for next patient. The whole working process in the conventional art has problems of potential safety hazards caused by improper use of the terminal and low utilization of the terminal. A method and system for controlling a medical device according to embodiments of the present disclosure are intended to solve the above technical problems.

In one embodiment, as shown in FIG. 1, a method for controlling a medical device is provided. The method is applied to a control system including an information detection apparatus, a device control apparatus and a terminal. The method includes the following steps.

In S1001, the information detection apparatus detects identification information of the terminal within a preset safety distance range, and sends the identification information to the device control apparatus.

Specifically, a specific value of the preset safety distance range is not specifically limited in this embodiment, provided that safety of the terminal is ensured in use. Optionally, the preset safety distance range may be 1 m, 2 m or 3 m, which may be selected according to an actual requirement. The information detection apparatus may send the identification information to the device control apparatus after detecting the identification information of the terminal within the preset safety distance range. Optionally, the information detection apparatus and the device control apparatus may communicate with each other by wired data transmission or by wireless data communication.

Optionally, the information detection apparatus and the device control apparatus may be different hardware devices or integrated in a same hardware device. The hardware may be arranged on the medical device. The terminal may be a mobile terminal, and the identification information thereof is coded information or an ID number of the terminal.

In S1002, the terminal determines a current permission function of the terminal according to an acquired target operation parameter when the identification information has been verified by the device control apparatus; the target operation parameter including a target region where the terminal is currently located and a target safety condition.

Specifically, the device control apparatus, after receiving the identification information sent by the information detection apparatus, may verify the identification information to determine legality thereof. An operation instruction can be sent to the device control apparatus only when the identification information of the terminal is legal. Optionally, the device control apparatus may match the identification information with preset identification information to verify whether the identification information is legal, and the identification information passes verification if the match is successful. Optionally, when the process of the device control apparatus matching the identification information with preset identification information is a complete match, that is, when the identification information and the preset identification information are exactly the same, the match is considered to be successful. When the identification information has been verified by the device control apparatus, a signal indicative of successful verification may be sent to the terminal, and the terminal acquires its target operation parameter. The target operation parameter includes a target region where the terminal is currently located and a target safety condition. The target region is a region where the terminal is currently located. The target safety condition is a safety condition where the terminal is currently in.

Optionally, the terminal may determine the target region according to its current position, and determine the target safety condition according to its current state. The target region may be a safety region or a non-safety region. The safety region may include a scanning room and an operation room. The non-safety region may include other regions other than the scanning room and the operation room. The current state of the terminal may include any one of being held, detached, and placed in a bracket. The “held” means that the technician holds the terminal, the “placed in a bracket” means that the terminal is attached to a rack of the medical device or the terminal is placed in a bracket next to a control terminal, and the “detached” means that the terminal is neither held by the technician nor placed in the bracket, that is, placed elsewhere. The terminal may acquire a current position through a GPS positioning apparatus installed therein to determine the target region. The current state of the terminal is obtained according to a signal acquired by a human body sensor and whether a charging apparatus performs charging, to determine the target safety condition.

Then, the terminal determines a current permission function of the terminal according to the acquired target operation parameter. The terminal may first configure a correspondence among safety regions, safety conditions and permission functions; that is, different target regions correspond to different permission functions under different safety conditions. For example, when the terminal is in the safety region and in the hand-held state, a patient can be scanned and examined by using all functions. When the terminal is in the non-safety region and in the detached state, the terminal has no permission function.

In S1003, the device control apparatus receives an operation instruction corresponding to the permission function and sent by the terminal, and controls the medical device to perform an operation corresponding to the operation instruction.

Specifically, the terminal, after determining the current permission function, can send an operation instruction to the device control apparatus under the permission function. The device control apparatus, after receiving the operation instruction, can control the medical device to perform the operation corresponding to the operation instruction. For example, if the operation instruction sent by the terminal received by the device control apparatus is to move the sickbed forward, the sickbed is controlled correspondingly to move forward. Optionally, the terminal, when sending the operation instruction to the control terminal, is required to send it to the medical device to prevent potential safety hazards during operation.

In S1004, the terminal switches a display mode to a preset target mode when a current state of the terminal satisfies a preset condition; the target mode is configured to display content to be displayed by the terminal.

Specifically, after the device control apparatus fixes the bed position, the technician may take the terminal to return to the operation room for image scanning. In this case, the terminal may detect again whether its current state satisfies a preset condition. The preset condition may be a condition set for an operation state of the terminal or a condition set for a position state of the terminal. When the preset condition is the condition set for the position state of the terminal, if the terminal is in a state of being in the operation room, it is considered that the preset condition is satisfied, and the display mode of the terminal is switched to a target mode. When the preset condition is the condition set for the operation state of the terminal, if the operation state of the terminal is in a state of being in communication with the control device or in the charged state, it is considered that the preset condition is satisfied, and the display mode of the terminal is switched to the target mode. The control device may be a device that controls the medical device to scan the patient to obtain a medical image, that is, a control terminal operated by the technician.

The target mode may be a display operation mode preset according to a user requirement, which is set to, such as, display operation guidelines for operating the control device, display device parameters of the medical device, display physical sign information of the patient, or display content of a monitor in the scanning room. The target mode is configured to display content to be displayed by the terminal, but specific display content is not limited in this embodiment. Certainly, the target mode may also be configured to indicate other operation modes of the terminal, for example, a video recording mode, in which a process of the technician operating the control device currently is recorded for a new technician to learn.

After the terminal is switched to the target mode, a scanning process of the medical image may be extended from one screen of a conventional control device to two screens: one screen is an operation screen of the control device and the other screen is a display screen of the terminal, which provides more convenience for the technician to scan the medical image of the patient.

Optionally, in some embodiments, the step of detecting, by the information detection apparatus, identification information of the terminal within a preset safety distance range includes: detecting, by the information detection apparatus, identification information of at least one terminal within the preset safety distance range, the preset safety distance range being 0 m to 3 m. That is, when a plurality of terminals are within the preset safety distance range, the information detection apparatus may detect a plurality of identification information and send the plurality of identification information to the device control apparatus. Optionally, the device control apparatus may acquire the plurality of identification information sent by the information detection apparatus and verify the plurality of identification information with the preset identification information one by one.

Optionally, in some embodiments, the step of determining, by the terminal, a current permission function of the terminal according to an acquired target operation parameter includes: determining, by the terminal, the current permission function of the terminal according to the target operation parameter and a preset correspondence between operation parameters and permission functions. Since the terminal is pre-configured with a correspondence between different operation parameters (including the safety region and the non-safety region) and different permission functions, the current permission function of the terminal can be determined according to the target operation parameter and the correspondence.

In one embodiment, as shown in FIG. 2, another method for controlling a medical device is provided. S1002 may include the following steps.

In S2001, the terminal detects whether the target region belongs to a preset safety region, and detects whether the target safety condition satisfies a preset safety condition, to obtain a detection result.

Specifically, the terminal, after obtaining the target region and the target safety condition of the terminal, can detect whether the target region belongs to a preset safety region, to obtain the detection result; that is, the target region is matched with the preset safety region, if the match is successful, it indicates that the target region belongs to the preset safety region, and otherwise, it indicates that the region does not belong to the preset safety region but belongs to the non-safety region. In addition, the terminal may also detect whether the target safety condition satisfies the preset safety condition, to obtain the detection result; that is, the target safety condition may be matched with the preset safety condition, if the match is successful, it indicates that the target safety condition belongs to the preset safety condition, and otherwise, the target safety condition does not belong to the preset safety condition.

In S2002, the terminal determines the current permission function of the terminal according to the detection result and the correspondence.

Specifically, the terminal may obtain a plurality of detection results when detecting the target region and the target safety condition. The plurality of detection results may also correspond to a variety of different permission functions. The plurality of detection results may be as follows.

Optionally, it is determined, according to the correspondence, that the permission function corresponding to the target region and the target safety condition is all functions of the terminal when the detection result is that the target region belongs to the preset safety region and the target safety condition satisfies the preset safety condition. That is, the terminal can enable all the functions when detecting that the target region belongs to the preset safety region and the target safety condition satisfies the preset safety condition.

Optionally, all the functions of the terminal are disabled when the detection result is that the target region does not belong to the preset safety region and the target safety condition does not satisfy the preset safety condition. That is, when the terminal detects that the target region does not belong to the preset safety region and the target safety condition does not satisfy the preset safety condition, it is determined that the terminal may be in the non-safety region and in a non-safety state, and the terminal is required to disable all the functions.

Optionally, it is determined, according to the correspondence, that the permission function corresponding to the target region is some functions of the terminal when the detection result is that the target region belongs to the preset safety region and the target safety condition does not satisfy the preset safety condition; or it is determined, according to the correspondence, that the permission function corresponding to the target safety condition is some functions of the terminal when the detection result is that the target region does not belong to the preset safety region and the target safety condition satisfies the preset safety condition. In this step, some functions corresponding to the case of belonging to the safety region and not satisfying the safety condition and some functions corresponding to the case of not belonging to the safety region and satisfying the safety condition may be the same or different. The terminal may enable some functions when the obtained detection result is such two cases.

In the method for controlling a medical device according to this embodiment, a detection result is obtained by detecting whether the target region belongs to the preset safety region and detecting whether the target safety condition satisfies the preset safety condition, and a permission function corresponding to the target region and the target safety condition is determined according to the detection result and the correspondence. In this embodiment, permission functions corresponding to the terminal may also be different under different detection results; that is, permission functions used by the terminal in different scenarios are different. Therefore, the method can enhance the safety of the terminal in the process of controlling the medical device.

Optionally, in some embodiments, the method further includes: detecting, by the terminal, the current state; and the step of detecting, by the terminal, the current state includes: detecting, by the terminal, whether a preset sensing signal is received, or whether the terminal is in a charged state, or position information of the terminal. It is determined that the current state of the terminal satisfies the preset condition if the terminal receives the sensing signal, the terminal is in a charged state, or the terminal is at a target position. Optionally, the step of detecting, by the terminal, whether a preset sensing signal is received may include: detecting whether the terminal receives a sensing signal sent by a sensor by Near Field Communication (NFC). The sensor may be installed on the control device and may emit a sensing signal over a certain distance. A coverage range of the sensing signal is a regional range of the operation room. It may be determined, by detecting whether the terminal receives the sensing signal, that the terminal satisfies the preset condition. Optionally, a manner in which the terminal detects whether it is in the charged state may include: detecting whether a battery current of the terminal exceeds a current threshold, and determining that the terminal is in the charged state if yes. Optionally, the position information of the terminal may be obtained by a user input, obtained by identification of an image taken by a camera in the operation room, or by a signal from the GPS positioning apparatus in the terminal. It may be determined, by detecting whether the position of the terminal is in a region of the operation room (i.e., target position), that the terminal satisfies the preset condition.

Optionally, in some embodiments, the content to be displayed by the terminal is preset content stored in the terminal, for example, operation guidelines for operating the control device. The preset content is pre-stored in the terminal. After the terminal switches the display mode to the preset target mode, the preset content is automatically displayed in the target mode. Thus, power consumption of communication between the terminal and the control device is reduced, and the operation complexity of the terminal is reduced.

Optionally, in some embodiments, the content to be displayed by the terminal is a display content sent by a control device, for example, device parameters of the medical device or displayed physical sign information of a subject. The display content sent by the control device may be sent according to an input instruction of the technician; that is, the control device can send the display content to the terminal according to a user requirement.

It should be understood that although steps in the flowcharts of FIG. 1 and FIG. 2 are displayed in sequence as indicated by the arrows, the steps are not necessarily performed in sequence in the order indicated by the arrows. Unless otherwise clearly specified herein, the steps are performed without any strict sequence limitation, and may be performed in other orders. In addition, at least some steps in FIG. 1 and FIG. 2 may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at a same moment, and may be performed at different moments. The sub-steps or stages are not necessarily performed in sequence, and the sub-steps or stages and at least some of other steps or sub-steps or stages of other steps may be performed in turn or alternately.

Therefore, the patent protection scope of the present disclosure shall be subject to the appended claims.

With the progress of society and the development of science and technology, most sickbeds currently used at the site of hospitals are controlled by an intelligent control device. Movement, fixation and the like of the sickbed can be controlled by a CPAN on a rack and/or a CTBOX in the operation room, or controlled by a wireless hand-held terminal.

Currently, when the wireless hand-held terminal is used in conjunction with an intelligent control device to move and fix the sickbed, there exist certain potential safety hazards, such as delay of a control signal of the hand-held terminal and invalid control of the hand-held terminal.

Based on this, there is a need to provide a method and system for controlling a medical device with respect to the problem of existence of certain potential safety hazards during the control of an existing hand-held terminal over the sickbed.

Referring to FIG. 4 and FIG. 5, an embodiment of the present disclosure provides a method for controlling a medical device, applied to a control system 20 including a detection apparatus 200 and control apparatus 202. The method includes the following steps.

In S3001, the detection apparatus 200 detects identification information of at least one terminal 104 within a preset safety distance range.

It may be understood that a specific value of the preset safety distance range is not specifically limited, provided that no potential safety hazards exist in use of the terminal 104. In one embodiment, the preset safety distance range may be set to 1 m. In one embodiment, the preset safety distance range may be set to 2 m. In one embodiment, the preset safety distance range may be set to 3 m. The specific value of the preset safety distance range may be selected according to an actual requirement.

In one embodiment, the detection apparatus 200 may detect the identification information of the terminal 104 only when the terminal 104 is within a safety detection distance range of the detection apparatus 200. In one embodiment, the identification information may be coded information of the terminal 104. In one embodiment, the identification information may also be an ID number.

In S3002, the control apparatus 202 acquires the identification information sent by the detection apparatus 200 and verifies the identification information.

It may be understood that a manner in which the control apparatus 202 acquires the identification information sent by the detection apparatus 200 is not limited, provided that the control apparatus 202 can acquire the identification information sent by the detection apparatus 200. In one embodiment, the control apparatus 202 may acquire the identification information sent by the detection apparatus 200 by wired data transmission. In one embodiment, the control apparatus 202 may also acquire the identification information sent by the detection apparatus 200 by wireless data transmission. In one embodiment, the wireless data transmission may be radio frequency signal transmission, Bluetooth signal transmission, or the like.

In one embodiment, a plurality of the identification information sent by the detection apparatus 200 is not limited. One or more pieces of identification information may be provided. In one embodiment, a plurality of identification information of the terminal 104 detected by the detection apparatus 200 within the preset safety distance range may be sent to the control apparatus 202 at the same time. Thus, the control apparatus 202 verifies the plurality of identification information one by one.

In S3003, the control apparatus 202 receives an operation instruction corresponding to the identification information and currently sent by the terminal 104 if a verification result is that the identification information is matched with preset identification information, and controls, based on the operation instruction, the medical device 206 to perform an operation corresponding to the operation instruction.

In one embodiment, “if a verification result is that the identification information is matched with preset identification information” means that the identification information is exactly the same as the preset identification information. The control apparatus 202 may determine that an identity of the current terminal 104 corresponding to the identification information is legal only when the identification information is exactly the same as the preset identification information. In one embodiment, if the identity of the current terminal 104 is legal, the control apparatus 202 receives an operation instruction sent by the current terminal 104, and generates a control command based on the operation instruction, so that the control apparatus 202 controls, based on the control command, the medical device 206 to perform an operation corresponding to the control command. In one embodiment, the medical device 206 may be a sickbed. In one embodiment, the operation may be sickbed movement, exposure, sickbed scanning and so on.

In one embodiment, in use, the terminal 104 is required to be operated toward the medical device 206 to prevent potential safety hazards during operation and improve safety. In one embodiment, the terminal 104 is required to be used between the medical device 206 and the detection apparatus 200.

In one embodiment, the detection apparatus 200 is communicatively connected to the control apparatus 202 and the terminal 104. In one embodiment, the control apparatus 202 is communicatively connected to the medical device 206.

In this embodiment, the terminal 104 can be detected within a safety distance range through the detection apparatus 200, and the control apparatus 202 cooperates with the terminal 104 to specifically operate the medical device 206. Potential safety hazards are prevented, so that a doctor can observe a patient while performing a specific operation on the medical device, to thereby enabling the doctor to control it more easily and conveniently, which is of higher safety.

In one embodiment, the preset safety distance range is 0 m to 3 m. In one embodiment, the detection apparatus 200 may detect the identification information of the terminal 104 only when the terminal 104 is within a safety detection distance range of the detection apparatus 200 (i.e., within 3 m around the detection apparatus 200). In one embodiment, one side of the detection apparatus 200 facing the medical device 206 may be set as a safety detection range, and one side of the detection apparatus 200 facing away from the medical device 206 may be set as a non-detection range.

In one embodiment, it may also be determined, by a camera according to a preset video algorithm, whether there is a person (whether there is a person can be determined by capturing a feature point of the person, such as head and shoulder, etc.) nearby an emergency stop button (arranged in the detection apparatus 200). If yes, an operation related to safety of a mobile terminal is allowed, and an operation direction of an operator is determined according to a hand-held mode of the terminal 104 operated by the person. In one embodiment, sickbed movement can be normally performed if the sickbed movement is performed toward the sickbed, and the sickbed movement is not allowed if no. The safety may be further improved through cooperation between the camera and the detection apparatus 200.

In one embodiment, the step of acquiring, by the control apparatus 202, the identification information sent by the detection apparatus 200, and verifying the identification information includes: acquiring, by the control apparatus 202, a plurality of identification information sent by the detection apparatus 200; and verifying the plurality of identification information and the preset identification information one by one.

In one embodiment, the control apparatus 202 is in one-to-one correspondence to the preset identification information. That is, one control apparatus 202 can only match one terminal 104. In one embodiment, the control apparatus 202, when receiving a plurality of identification information, may verify the plurality of identification information one by one, and may stop verifying other pieces of identification information until a verification result is that the identification information is matched with the preset identification information. The safety in use is improved through such verification.

In one embodiment, the step of detecting, by the detection apparatus 200, identification information of at least one terminal 104 within a preset safety distance range includes: detecting, by the detection apparatus 200, the identification information of the at least one terminal 104 within the preset safety distance range in a preset cycle.

It may be understood that specific time of the preset cycle is not limited, provided that the detection apparatus 200 detects the identification information of the at least one terminal 104 within the preset safety distance range. In one embodiment, the preset cycle may be set to 200 ms (milliseconds). In one embodiment, the preset cycle may be set to 100 ms (milliseconds). The specific time of the preset cycle may be set according to an actual requirement.

In one embodiment, prior to the step of receiving, by the control apparatus 202, an operation instruction corresponding to the identification information and currently sent by the terminal 104 if a verification result is that the identification information is matched with preset identification information, and controlling, based on the operation instruction, the medical device 206 to perform an operation corresponding to the operation instruction, the method further includes: returning to the step of acquiring, by the control apparatus 202, identification information sent by the detection apparatus 200 and verifying the identification information if the verification result is that the identification information is not matched with the preset identification information.

In one embodiment, when the verification result is that the identification information is not matched with the preset identification information, the control apparatus 202 re-acquires the identification information sent by the detection apparatus 200, and the detection apparatus 200 may stop verifying the identification information until the verification result is that the identification information is matched with the preset identification information. This improves the safety of the match between the control apparatus 202 and the terminal 104.

In one embodiment, the identification information is ID information of the terminal 104. In one embodiment, the ID information may be an identity number, a unique code, an exclusive number, and so on. In one embodiment, each terminal 104 corresponds to one piece of ID information.

Referring to FIG. 5, an embodiment of the present disclosure provides a control system 20 including a detection apparatus 200 and control apparatus 202. The detection apparatus 200 is configured to detect identification information of at least one terminal 104 within a preset safety distance range.

In one embodiment, the control apparatus 202 may be composed of a single-chip microprocessor and a display. In one embodiment, the control apparatus 202 may also be composed of a CPU (central processing unit) and a display.

In one embodiment, “if a verification result is that the identification information is matched with preset identification information” means that the identification information is exactly the same as the preset identification information. The control apparatus 202 may determine that an identity of the current terminal 104 corresponding to the identification information is legal only when the identification information is exactly the same as the preset identification information. In one embodiment, if the identity of the current terminal 104 is legal, the control apparatus 202 receives an operation instruction sent by the current terminal 104, and generates a control command based on the operation instruction, so that the control apparatus 202 controls, based on the control command, the medical device 206 to perform an operation corresponding to the control command. In one embodiment, the operation may be sickbed movement, exposure, scanning of the medical device 206 and so on.

In one embodiment, the detection apparatus 200 further detects, based on a preset cycle, the identification information of the at least one terminal 104 within the preset safety distance range. It may be understood that specific time of the preset cycle is not limited, provided that the detection apparatus 200 detects the identification information of the at least one terminal 104 within the preset safety distance range. In one embodiment, the preset cycle may be set to 200 ms (milliseconds). In one embodiment, the preset cycle may be set to 100 ms (milliseconds). The specific time of the preset cycle may be set according to an actual requirement.

In one embodiment, the detection apparatus 200 includes a radio frequency identification card reader 2002 and an emergency stop key 2004. The radio frequency identification card reader 2002 is communicatively connected to the control apparatus 202 and at least one terminal 104.

The emergency stop key 2004 is arranged adjacent to the radio frequency identification card reader 2002. The emergency stop key 2004 is configured to control an emergency stop of the control system 20.

In one embodiment, the radio frequency identification card reader 2002 and the control apparatus 202 may be communicatively connected by wireless data communication.

Signal transmission may be more secure and stable by using an RFID (Radio Frequency Identification) technology. In one embodiment, when an emergency (such as a device failure) occurs in the control system 20, an emergency stop of the control system 20 can be controlled through the emergency stop key 2004.

Based on the above, in the present disclosure, the terminal 104 can be detected within a safety distance range through the detection apparatus 200, and the control apparatus 202 cooperates with the terminal 104 to specifically operate the medical device 206. Potential safety hazards are prevented, so that a doctor can observe a patient while performing a specific operation on the medical device, to thereby enabling the doctor to control it more easily and conveniently, which is of higher safety.

The technical features in the above embodiments may be randomly combined. For concise description, not all possible combinations of the technical features in the above embodiments are described. However, all the combinations of the technical features are to be considered as falling within the scope described in this specification provided that they do not conflict with each other.

The above embodiments only describe several implementations of the present disclosure, which are described specifically and in detail, and therefore cannot be construed as a limitation on the invention patent scope. It should be pointed out that those of ordinary skill in the art may also make several changes and improvements without departing from the ideas of the present disclosure, all of which fall within the protection scope of the present disclosure. Therefore, the patent protection scope of the present disclosure shall be subject to the appended claims.

When a human body is detected using a medical device, in general, firstly, a patient lies on a sickbed, and through a mobile terminal, a doctor operates a position of the sickbed and positions a to-be-scanned site; then, the doctor uses the mobile terminal to control a device to scan the patient and controls a computer through the mobile terminal to process data scanned by the device and to display scanned data and scanned images at the same time. However, the above method has the problem of low safety.

Based on this, there is a need to provide a terminal operation method, apparatus and storage medium capable of improving the safety with respect to the above technical problem.

The device operation method according to the present disclosure can be applied to an application environment shown in FIG. 6. A mobile terminal 300 may communicate with a control terminal 302 or with a device 304. The control terminal 302 may also communicate with the device 304. Further, the mobile terminal 300 and the device 304 may be in a wireless connection or a wired connection. In the embodiment of the present disclosure, the device 304 is provided with a WIFI routing component, and the mobile terminal 300 may communicate with the device 304 by WIFI connection. The control terminal 302 and the device 304 may be in a wireless connection or a wired connection. In the embodiment of the present disclosure, the control terminal 302 and the device 304 are in a wired connection through a cable. the mobile terminal 300 and the control terminal 302 may be in a wireless connection or a wired connection. The mobile terminal 300, the control terminal 302 and the device 304 are generally in a same local area network. In addition, the mobile terminal 300 may be a mobile phone, a tablet computer, a hand-held computer and other mobile electronic products. The control terminal 302 may be a personal laptop computer, a desktop computer, or the like. The device 304 may be a CT device or the like.

Referring to FIG. 7, in the embodiment of the present disclosure, a process of scanning the patient may be as follows: firstly, a patient enters a scanning room from a patients' access door, and then follows a technician's instructions to lie on a sickbed; the technician holds the mobile terminal, operates the mobile terminal to control the sickbed to rise and advance, and positions a to-be-scanned site of the patient; then, the technician returns to the operation room from a technicians' access door with the mobile terminal, and operates the control terminal to complete examination on the patient; finally, the technician enters the scanning room from the technicians' access door with the mobile terminal, tells the patient to go down the sickbed, adjusts the sickbed, and waits for next patient.

The method according to the present disclosure is described in detail below with a specific embodiment. It is to be noted that the embodiment of the present disclosure may be performed by a terminal operation apparatus or a terminal. The terminal is the mobile terminal or the control terminal in FIG. 6. The following embodiment is described by taking the mobile terminal as an execution subject.

In one embodiment, a terminal operation method is provided. This embodiment relates to a specific process of how the mobile terminal enables a permission function according to a target operation parameter. As shown in FIG. 8, the method may include the following steps.

In S4001, a target operation parameter of the terminal is acquired, the target operation parameter including a target region and a target safety condition.

The terminal here refers to the mobile terminal. When a human body is examined, a region may be generally divided into a safety region and a non-safety region.

Specifically, when the human body is examined using a CT device, the mobile terminal may first obtain a region and a safety condition of the mobile terminal and take the region as the target region. The safety condition serves as the target safety condition, and the target region and the target safety condition are used as the target operation parameter.

In S4002, a permission function corresponding to the target operation parameter is determined according to a preset correspondence between operation parameters and permission functions.

Prior to the examination on the human body, the mobile terminal may first configure the safety region, the non-safety region and the safety condition; after the safety region and the safety condition are configured, the mobile terminal may continuously configure a correspondence between operation parameters (i.e., the safety region and the safety condition) and permission functions, that is, set different permission functions for different operation parameters, and enable the two to correspond to each other. The mobile terminal may configure the correspondence on its display interface or configure the correspondence on the control terminal. After the configuration, the control terminal is associated with the mobile terminal, and the mobile terminal can use the configured correspondence. In an example, a manner in which the mobile terminal configures the safety region and the safety condition may be obtained with reference to FIG. 8a.

Specifically, after obtaining the target operation parameter, the mobile terminal may search the pre-configured correspondence for the permission function corresponding to the target operation parameter.

In an example, as shown in FIG. 8b, different corresponding permission functions under different safety conditions when the mobile terminal is in different target regions are shown, from which it can be seen that different operation parameters correspond to different permission functions.

In S4003, the permission function corresponding to the target operation parameter is enabled.

specifically, after obtaining the permission function corresponding to the target operation parameter, the mobile terminal can enable the permission function. In this way, when examining a human body, the technician can control the sickbed to move or control the CT device to scan the human body by operating the enabled permission function.

According to the terminal operation method, a target operation parameter of a terminal is acquired, the target operation parameter includes a target region and a target safety condition, a permission function corresponding to the target operation parameter is determined according to a preset correspondence between operation parameters and permission functions, and the permission function corresponding to the target operation parameter is enabled. In this embodiment, the enabled permission function is determined according to two parameters, i.e., the target region and the target safety condition, that is, different target regions and target safety conditions correspond to different permission functions; in this way, when a human body is examined, all the functions may not be blindly used for examination, and only the permission function corresponding to the target operation parameter is enabled. Therefore, the method can enhance safety of the terminal. At the same time, when a CT device is operated using the terminal, safety of the CT device may also be enhanced, thereby reducing occurrence of some unexpected risks.

In another embodiment, this embodiment relates to a specific process of how the mobile terminal acquires the target operation parameter. On the basis of the above embodiment, as shown in FIG. 9, the method may include the following steps.

In S5001, a current position of the terminal and a current state of the terminal are acquired.

The current state of the terminal refers to a current state of the mobile terminal. The state may include any one of being held, detached, and placed in a bracket. The “held” means that the technician holds the mobile terminal, the “placed in a bracket” means that the mobile terminal is attached to a rack of the CT device or the mobile terminal is placed in a bracket next to the control terminal, and the “detached” means that the mobile terminal is neither held by the technician nor placed in the bracket, that is, placed elsewhere. Optionally, as shown in FIG. 9a, a human body sensor may be arranged at the back of the mobile terminal, and whether the mobile terminal is hand-held (for example, whether induced capacitance changes) may be known by using a signal acquired by the human body sensor. Optionally, a charging apparatus may be arranged in the rack of the CT device or the bracket next to the control terminal. Whether the mobile terminal is placed in the bracket can be known according to whether the charging apparatus performs charging. The current position of the terminal refers to a current position of the mobile terminal. Generally, a plurality of Bluetooth beacons may be arranged in the operation room and the scanning room, and each Bluetooth beacon may be communicatively connected to the mobile terminal.

In addition, the current state of the terminal may further include: a current operation state of the CT device, for example, when the CT device sets scanning parameters, performs scanning, performs correction, reconstructs an image, and so on. When the mobile terminal obtains the safety condition, the target safety condition can be obtained by comprehensively considering the current state of the mobile terminal and the current operation state of the CT device. Different states may correspond to different safety conditions. By comprehensively considering current states of various devices, the safety conditions set can be more comprehensive, so that the operational safety of the mobile terminal is higher.

Specifically, the mobile terminal can calculate the current position of the mobile terminal through signal strength of each Bluetooth beacon received. Certainly, the current position of the mobile terminal may also be obtained through a positioning apparatus such as a GPS built in the mobile terminal. At the same time, the mobile terminal may obtain the current state of the mobile terminal through the signal acquired by the human body sensor and whether the charging apparatus performs charging. In an example, if the signal acquired by the human body sensor changes, it can be considered that the current state of the mobile terminal is “hand-held”, or if the charging apparatus is performing charging, it can be considered that the current state of the mobile terminal is “placed in the bracket”, and in other cases, it can be considered that the current state of the mobile terminal is “detached”. For example, the mobile terminal is placed on a desktop. In addition, when the current state of the mobile terminal is “detached”, optionally, a screen lock time can be set, such as 3 s. The mobile terminal may automatically lock a screen after being detached for 3 s, and a user can continue to use it only after re-authentication.

In S5002, the target region where the terminal is located is determined according to the current position of the terminal, and the target safety condition corresponding to the terminal is determined according to the current state of the terminal.

The safety condition is all the states of the mobile terminal, including hand-held, detached, placed in the bracket, and so on. A position of the safety region may also be obtained through the signal strength of each Bluetooth beacon.

Specifically, after obtaining its current position, the mobile terminal may match its current position with the position of the safety region, so as to obtain a region corresponding to the current position, which may be a safety region or a non-safety region. The region corresponding to the current position is recorded as the target region. In addition, the mobile terminal can obtain a state corresponding to the mobile terminal through the human body sensor and the charging apparatus. The corresponding state is recorded as the target safety condition.

In S5003, the target region and the target safety condition are used as the target operation parameter.

Specifically, the mobile terminal can combine the target region and the target safety condition as the target operation parameter after obtaining the target region and the target safety condition.

In the terminal operation method according to this embodiment, the current position of the terminal and the current state of the terminal are acquired, a target region where the terminal is located is determined according to the current position of the terminal, a target safety condition corresponding to the terminal is determined according to the current state of the terminal, and the target region and the target safety condition are used as the target operation parameter. In this embodiment, the target operation parameter is determined according to the current position and the current state of the terminal (i.e., the mobile terminal); that is, the target operation parameter is determined according to an actual position and an actual state of the mobile terminal. Therefore, when the permission function is enabled using the target operation parameter, the enabled permission function is also a permission function in line with reality, that is, a permission function that can be operated safely. Thus, the method can further improve the operational safety of the mobile terminal.

In another embodiment, another terminal operation method is provided. This embodiment relates to a specific process of how the mobile terminal determines a corresponding permission function according to a target operation parameter and a preset correspondence between operation parameters and permission functions. On the basis of the above embodiment, as shown in FIG. 10, the method may include the following steps.

In S6001, it is detected whether the target region belongs to a preset safety region, and it is detected whether the target safety condition satisfies a preset safety condition, to obtain a detection result.

One or two or other numbers of preset safety regions may be provided. Two safety regions are provided in this embodiment, of which one is an operation room and the other is a scanning room. The safety region may be in a shape of a circle or a rectangle or other regular or irregular polygons. The circular safety region can generally be established with the WIFI routing component of the CT device as a center and with a specific length as a radius. For example, the set shape of the safety region is shown in FIG. 10a.

Specifically, the mobile terminal, after obtaining the target region and the target safety condition of the terminal, can detect whether the target region belongs to a preset safety region, to obtain the detection result; that is, the target region is matched with the preset safety region, if the match is successful, it indicates that the target region belongs to the preset safety region, and otherwise, it indicates that the region does not belong to the preset safety region but belongs to the non-safety region. In addition, the mobile terminal may also detect whether the target safety condition satisfies the preset safety condition, to obtain the detection result; that is, the target safety condition may be matched with the preset safety condition, if the match is successful, it indicates that the target safety condition belongs to the preset safety condition, and otherwise, the target safety condition does not belong to the preset safety condition.

In S6002, a permission function corresponding to the target region and the target safety condition is determined according to the detection result and the correspondence.

Specifically, the mobile terminal may obtain a plurality of detection results when detecting the target region and the target safety condition. The plurality of detection results may also correspond to a variety of different permission functions. The plurality of detection results may be as follows.

Optionally, it is determined, according to the correspondence, that the permission function corresponding to the target region and the target safety condition is all functions of the terminal when the detection result is that the target region belongs to the preset safety region and the target safety condition satisfies the preset safety condition. That is, when detecting that the target region belongs to the preset safety region and the target safety condition satisfies the preset safety condition, the mobile terminal can enable all the functions, and scan and examine the human body by using all the functions.

Optionally, all the functions of the terminal are disabled when the detection result is that the target region does not belong to the preset safety region and the target safety condition does not satisfy the preset safety condition. That is, when the mobile terminal detects that the target region does not belong to the preset safety region and the target safety condition does not satisfy the preset safety condition, it is determined that the mobile terminal may be in the non-safety region and in a non-safety state, and the mobile terminal is required to disable all the functions and cannot scan and examine the human body at will.

Optionally, the mobile terminal may acquire a latest current position and a latest current state in real time (at any time), and when the target region of the current position and the safety condition that the current state satisfies change, may update the corresponding permission function in real time and perform corresponding processing.

In the terminal operation method according to this embodiment, a detection result is obtained by detecting whether the target region belongs to the preset safety region and detecting whether the target safety condition satisfies the preset safety condition, and a permission function corresponding to the target region and the target safety condition is determined according to the detection result and the correspondence. In this embodiment, permission functions corresponding to the mobile terminal may also be different under different detection results; that is, permission functions used by the mobile terminal in different scenarios are different. Therefore, the method can enhance the safety of the mobile terminal.

In another embodiment, another terminal operation method is provided. This embodiment relates to a specific process of how the mobile terminal determines a user permission according to a user identification. On the basis of the above embodiment, as shown in FIG. 11, the method may further include the following steps.

In S7001, a user identification is acquired.

The user identification may be a user password, a user mobile communication number, a user ID number, a user communication software number, or the like.

Specifically, when a user is to log in the mobile terminal, a user identification can be entered on a login interface of the mobile terminal, so that the mobile terminal can obtain the user identification entered by the user.

In S7002, a user permission is determined according to the user identification.

Specifically, the mobile terminal, after obtaining the user identification entered by the user, may match the entered user identification with a preset user identification. When the match is successful, it can be determined that the user corresponding to the user identification logs in successfully, and the mobile terminal can be used.

In the terminal operation method according to this embodiment, a user identification is acquired, and a user permission is determined according to the user identification. In this embodiment, the user permission is determined according to the user identification, and this can avoid the problem of damages to the mobile terminal caused by arbitrary use of the mobile terminal by some people without the user permission. Therefore, the method can improve the safety of the mobile terminal.

In another embodiment, another terminal operation method is provided. This embodiment relates to a specific process of how the mobile terminal enables a safety level function corresponding to the user identification when the user permission is satisfied. On the basis of the above embodiment, as shown in FIG. 12, the method may further include the following steps.

In S8001, an operation level corresponding to the user identification is acquired when the user permission is satisfied.

Prior to the use of the mobile terminal, different operation levels may be preset for different user identifications; that is, a correspondence between user identifications and operation levels may be established. In an example, an operation level corresponding to a first user identification is 1, an operation level corresponding to a second user identification is 2, and so on.

Specifically, when the mobile terminal obtains that the user identification entered by the user satisfies the user permission, an operation level corresponding to the user identification can be obtain obtained from a preset mapping relationship between user identifications and operation levels.

In S8002, a safety level function corresponding to the operation level is acquired according to a preset correspondence between operation levels and safety level functions.

After setting different operation levels for different user identifications, the mobile terminal may also set a corresponding safety level function for each operation level, that is, set different safety level functions for different operation levels, and establish a correspondence between the operation levels and the safety level functions. In an example, the safety level function corresponding to the operation level 1 may be “bed-movement enabled”, the safety level function corresponding to the operation level 2 may be “bed-movement enabled; scanning enabled”, and so on.

Specifically, after obtaining the operation level corresponding to the user identification, the mobile terminal may also obtain a safety level function corresponding to the operation level according to a correspondence between operation levels and safety level functions.

In S8003, the safety level function corresponding to the operation level is enabled.

Specifically, the mobile terminal, after obtaining the safety level function corresponding to the operation level, can enable the function.

In the terminal operation method according to this embodiment, when a user permission is satisfied, an operation level corresponding to a user identification can be acquired, a safety level function corresponding to the operation level is acquired according to a preset correspondence between operation levels and safety level functions, and the safety level function corresponding to the operation level is enabled. In this embodiment, since different user identifications correspond to different operation levels, that is, correspond to different safety level functions, this can also further avoid an accident caused by misoperation of some users on functions that are not operable, thereby improving the safety of the mobile terminal.

With the rapid development of medical imaging devices (also known as medical devices), an increasing number of disease diagnoses rely on detection and analysis of medical images. In order to facilitate a doctor to operate a medical device to scan a patient, a mobile terminal communicatively connected to the medical device has been currently added to assist the scanning of the medical device. The doctor can use the mobile terminal to control a position of the sickbed, and then return to a console of the medical device to control the medical device to scan the patient.

Currently, when the doctor returns to a console with the mobile terminal, a display mode of an interface of the mobile terminal is still an operation interface for controlling the sickbed, or the mobile terminal is in a screen-off state when placed on a special charging base near the console. In this way, the mobile terminal has low utilization and poor interactivity.

Based on this, there is a need to provide a terminal mode switching method, apparatus, terminal, system and readable storage medium with respect to the problem of low utilization and poor interactivity of the mobile terminal in the conventional art.

The terminal mode switching method according to the embodiment of the present disclosure can be applied to a scenario shown in FIG. 16. In a current working process of a medical device, firstly, a patient enters a scanning room from a patients' access door, and then follows a technician's instructions to lie on a sickbed; the technician holds a terminal, operates the terminal to control the sickbed to rise and advance, and positions a to-be-scanned site of the patient; then, the technician returns to the operation room from a technicians' access door with the terminal, and operates a control device to complete examination on the patient; finally, the technician enters the scanning room from the technicians' access door with the terminal, tells the patient to go down the sickbed, and waits for next patient. However, when the technician returns from the technician access door to the operation room with the terminal to operate the control device, the display mode of the interface of the terminal is still the operation interface for controlling the sickbed, or the terminal is in a screen-off state when placed on a special charging base near the control device. In this way, the terminal has low utilization and poor interactivity. The terminal mode switching method, apparatus, terminal, system and readable storage medium according to the embodiments of the present disclosure are intended to solve the above technical problem.

It is to be noted that the following method embodiment may be performed by a terminal mode switching apparatus. The apparatus may be implemented as part or all of a terminal by means of software, hardware, or a combination of hardware and software. The terminal may be the mobile terminal in the conventional art. For example, the following method embodiment is performed by a terminal.

FIG. 17 is a schematic flowchart of a terminal mode switching method according to an embodiment. This embodiment relates to a specific process of switching, by a terminal, a display mode to a target mode. As shown in FIG. 17, the method includes the following steps.

In S9001, a current state of a terminal is detected.

Specifically, the terminal first detects its current state. The terminal may be a mobile terminal communicatively connected to a control device. The control device may be a device that controls a medical device to scan a subject to obtain a medical image. The current state may be a current operation state or position state of the terminal. The operation state may be a state of controlling the sickbed, a state of communicating with the control device or a charged state. The position state may be a state of being in the scanning room or a state of being in the operation room. Optionally, the position state of the terminal may also be obtained from the operation state thereof. For example, when the position state of the terminal is the state of controlling the sickbed, it can be determined that the terminal is in the state of being in the scanning room; when the position state of the terminal is the state of communicating with the control device or the charged state, it can be determined that the terminal is in the state of being in the operation room.

In S9002, a display mode of the terminal is switched to a preset target mode if the current state of the terminal satisfies a preset condition; the target mode is configured to display content to be displayed by the terminal.

Specifically, the terminal may switch the display mode to the preset target mode when the current state detected by the terminal satisfies the preset condition. The preset condition may be a condition set for the operation state of the terminal or a condition set for the position state of the terminal. When the preset condition is the condition set for the position state of the terminal, if the terminal is in a state of being in the operation room, it is considered that the preset condition is satisfied, and the display mode of the terminal is switched to a target mode. When the preset condition is the condition set for the operation state of the terminal, if the operation state of the terminal is in a state of being in communication with the control device or in the charged state, it is considered that the preset condition is satisfied, and the display mode of the terminal is switched to the target mode.

The target mode may be a display operation mode preset according to a user requirement, which is set to, such as, display operation guidelines for operating the control device, display device parameters of the medical device, display physical sign information of the subject, or display content of a monitor in the scanning room. The target mode is configured to display content to be displayed by the terminal, but specific display content is not limited in this embodiment. Certainly, the target mode may also be configured to indicate other operation modes of the terminal, for example, a video recording mode, in which a process of the technician operating the control device currently is recorded for a new technician to learn.

According to the terminal mode switching method, the terminal first detects a current state; and a display mode of the terminal is switched to a preset target mode if the current state satisfies a preset condition. The target mode is configured to display content to be displayed by the terminal. In the method, when a technician returns to an operation room with the terminal and no longer controls a sickbed, the terminal can automatically change the display mode to a target mode set as needed, which greatly improves the utilization of the terminal and also improves interactivity of the terminal in use.

Optionally, in some embodiments, the step of detecting a current state of a terminal includes: detecting whether the terminal receives a preset sensing signal, or whether the terminal is in a charged state, or position information of the terminal.

Optionally, the step of detecting whether the terminal receives a preset sensing signal may include: detecting whether the terminal receives a sensing signal sent by a sensor by Near Field Communication (NFC). The sensor may be installed on the control device and may emit a sensing signal over a certain distance. A coverage range of the sensing signal is a regional range of the operation room. It may be determined, by detecting whether the terminal receives the sensing signal, that the terminal enters the operation room. Optionally, a manner of detecting whether the terminal is in the charged state may include: detecting whether a battery current of the terminal exceeds a current threshold, and determining that the terminal is in the charged state if yes. A special charging base of the terminal is generally arranged near the console. It may be determined, by detecting whether the terminal is in the charged state, that the terminal enters the operation room. Optionally, the position information of the terminal may be obtained by a user input, obtained by identification of an image taken by a camera in the operation room, or by a signal from a positioner in the terminal. It may be determined, by detecting whether the position of the terminal is in a region of the operation room (i.e., target position), that the terminal enters the operation room.

Optionally, different modes may also be switched to according to current state information of the terminal. For example, when the terminal is in the operation room, an operation mode may be switched to and an operation interface is displayed. When the terminal is within a certain range of the medical device, it is considered that the user is placing the patient, a placement mode may be switched to, and a placement interface is displayed; specifically, a real-time video of the patient shot by a top camera in the operation room at this time, a pre-shot positioning video and a pre-set medical scanning target region can be displayed. When the terminal is located far away from the medical device, it is considered that the user is required to use the terminal to read the video, a video reading mode may be switched to, and a sequence of recently shot images is displayed first.

Optionally, in some embodiments, if the terminal receives the sensing signal or the terminal is in the charged state or the terminal is at the target position, it can be determined that the current state of the terminal satisfies a preset condition; that is, the terminal enters the operation room at this time, and its display mode can be switched to the target mode. This setting can ensure that when the technician returns to the operation room to scan the subject, the terminal switches the display mode instead of displaying the mode of controlling the sickbed, which improves the utilization of the terminal, also improves the safety of the subject during the scanning, and avoids safety accident caused by misoperation of the technician on the terminal.

Optionally, in some embodiments, the content to be displayed by the terminal is preset content stored in the terminal, for example, operation guidelines for operating the control device. The preset content is pre-stored in the terminal. After the terminal switches to the target mode, the preset content is automatically displayed in the target mode. Thus, power consumption of communication between the terminal and the control device is reduced, and the operation complexity of the terminal is reduced.

In S1100, the display content sent by the control device is received.

In S1101, the display content sent by the control device is displayed in the target mode.

Specifically, the communication connection between the terminal and the control device may be a wireless communication connection or a wired communication connection. In the case of the wired communication connection, the technician may connect a connecting line with the terminal when the terminal is in the operation room. In the case of the wireless communication connection, wireless data communication may be radio frequency transmission, Bluetooth signal transmission, or the like. The terminal, after receiving the display content sent by the control device, may display the display content in the target mode.

In the terminal mode switching method according to this embodiment, a terminal may receive display content sent by a control device, and displays the display content sent by the control device in a target mode. Thus, the user can enable the terminal to display the corresponding display content as needed, which further improves the utilization of the terminal as well as interaction between users.

It should be understood that although steps in the flowcharts of FIG. 17 and FIG. 18 are displayed in sequence as indicated by the arrows, the steps are not necessarily performed in sequence in the order indicated by the arrows. Unless otherwise clearly specified herein, the steps are performed without any strict sequence limitation, and may be performed in other orders. In addition, at least some steps in FIG. 17 and FIG. 18 may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at a same moment, and may be performed at different moments. The sub-steps or stages are not necessarily performed in sequence, and the sub-steps or stages and at least some of other steps or sub-steps or stages of other steps may be performed in turn or alternately.
