Infusion pumps and syringe pumps, are instruments that can accurately control the flow rate of infusion to ensure that a drug can enter a patient's body safely at a uniform speed and in an accurate dose. Infusion pumps and syringe pumps can also improve the efficiency and flexibility of clinical drug delivery operations and reduce nursing workload.
When treating some infectious diseases, patients are usually located in the isolation ward, and the patients usually need continuous infusion. During ward rounds, the medical staff need to pay attention to the patient's medication situation. At such times, however, the medical staff typically need to be far away from the infusion pump, such that the medical staff cannot obtain clear information through the display of the pumps.
In addition to infusion pumps and syringe pumps, patients may also use other medical devices such as ventilators. During ward rounds, medical staff may also need to view the information displayed by various medical devices from a distance. Currently, medical staff are required to approach and manually operate the medical devices to display the contents of the medical devices. The display efficiency of the medical devices is low, and the medical staff are unable to view the information efficiently.
The invention provides a display method and apparatus for a medical device, an electronic device and a storage medium, aiming to solve the above technical problems in the prior art.
The technical solution of the invention and how the technical solution of the invention solves the above technical problems will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the invention will be described below in conjunction with the accompanying drawings.
S101, if it is determined that a target is within a preset range of the medical device, a distance between the target and the medical device is measured. The target is used to represent a user who is viewing the medical device.
Exemplarily, the medical device may be a device used for treatment and care, for example, it may be an infusion pump, a syringe pump, or a ventilator, and the like. When a patient is using a medical device, a user is required to check the medical device to ensure the health and safety of the patient. For example, the user can be medical staff such as a doctor or a nurse. For some patients, the medical staff should not be too close and need to keep a certain distance from the patient to view the medical device. Therefore, it is necessary for the medical device to automatically display the treatment of the patient and the use of the medical device. For example, where the medical device is an infusion pump, the infusion pump can display infusion speed, infusion volume, and infusion medicine through its own display screen.
The medical device is provided with a target detection device, a distance detection device, and a processor. The target detection device detects whether or not a target is present within a preset range in real time or at regular intervals, and sends a detection result to the processor. The processor determines whether or not to measure the distance between the target and the medical device based on the detection result. If the detection result is that a target is located within the preset range, the distance detection device is controlled to measure the distance between the target and the medical device. The target detection device includes one or more of a millimeter wave radar, an infrared sensor, an ultrasonic sensor or an image acquisition device. The distance detection device includes one or more of a millimeter wave radar, an infrared sensor, an ultrasonic sensor or an image acquisition device.
In one example, the target detection device and the distance detection device may be the same device. For example, the medical device may be provided with a millimeter wave radar, and the millimeter wave radar may then used to determine both the presence of the target within the preset range and the distance between the target and the medical device. In another example, the target detection device and the distance detection device may be different devices, for example, the target detection device is an infrared sensor provided on the medical device, and the distance detection device is a millimeter wave radar provided on the medical device, such that the infrared sensor may be used for determining whether or not a target is present within the preset range, and the millimeter wave radar is used for measuring the distance between the target and the medical device.
A preset range of the medical device is set in advance, and the medical device determines whether there is a target present within the preset range, and if there is, the medical device may measure the distance between the target and the medical device. For example, the preset range may be a range centered on the medical device with a preset distance as a radius. The target may be a user who needs to view the medical device, for example, it may be a medical staff member responsible for checking a ward. The medical device may determine in real time whether there is a medical staff member within the preset range, that is, determine whether there is a medical staff member near the medical device. If so, the medical device may determine that the medical staff member is a target, that is, there is a target within the preset range, and then measure the distance between the medical staff member and the medical device. For example, a camera or other equipment may be arranged on the medical device, and images within the preset range may be acquired by the camera, and a preset target recognition algorithm may be used to identify whether there is a target within the preset range. Based on the position of the target in the image, a distance between the target and the medical device can be determined. In this embodiment, the preset target recognition algorithm is not specifically limited. For example, the target recognition algorithm may be a face recognition algorithm.
The target may be any user or a pre-registered member of the medical staff. For example, as long as a user is within the preset range of the medical device, the user can be considered as a target, and the distance between the user and the medical device is measured. Alternatively, the distance between the medical staff member and the medical device may be measured only if a pre-registered identified medical staff member is within the preset range. For example, when someone is within the preset range, it is determined whether the user within the preset range is a pre-registered medical staff member by face recognition, and if so, the user is treated as a target, and the distance between the user and the medical device is measured, and if not, there is no need to measure the distance between the user and the medical device.
S102, according to the distance between the target and the medical device, the content to be displayed for the medical device is determined.
Exemplarily, the distance between the target and the medical device may be determined as a target distance, and after the target distance is determined, the content to be displayed for the medical device may be determined according to the target distance. The correlation between different distances and contents to be displayed may be preset, and after the target distance is determined, the content to be displayed associated with the target distance may be determined. For example, when the distance between the target and the medical device is 1 meter, the associated contents to be displayed might be the infusion speed, the infusion time, the infusion volume, and the infused drug; when the distance between the target and the medical device is 5 meters, the associated contents to be displayed might be only the infusion speed and the infusion volume.
The content to be displayed may include displayed data such as the treatment condition of the patient or the use condition of the medical device, and different contents to be displayed may correspond to different display modes. For example, the display mode may include a font size and a font color of the displayed data, and the like. The further the distance between the target and the medical device, the larger the font size may be and the brighter the font color may be. For example, when the distance between the target and the medical device is 1 meter, the font color is white; when the distance between the target and the medical device is 5 meters, the font color is bright yellow.
A medical device such as an infusion pump or other medical device may include a display, and the content to be displayed may be adjusted according to the distance between the target and the medical device. When the target is far away from the medical device, the font of the content can be enlarged. For example, if the information to be displayed might be only the name of the drug and the infusion rate, which allows the medical staff to observe the important content more clearly. When as distance between the target and the medical device becomes smaller, more content can be added, such as the amount of the infusion. When the target is standing in front of the medical device, for example, the target distance is within 1 meter, then the medical device might display all the information required by the target.
In this embodiment, the content to be displayed for the medical device is determined according to the distance between the target and the medical device, comprising: according to the distance between the target and the medical device and a preset correlation between the distance and a display mode, determining the content to be displayed for the medical device, as well as a rotation mode, font size and font color of the content to be displayed.
Specifically, a correlation between different distances and display modes is preset, for example, a correlation between different distance ranges and the display modes may be preset. After obtaining the distance between the target and the medical device, a distance range within which the target is located is determined, and the corresponding display mode is determined according to the preset correlation. For example, when the distance between the target and the medical device is between 1 meter and 2 meters, the corresponding display mode may be to display real-time data, such as the infusion speed and the infusion volume, on the display screen in a size of Song font No. 4 and a white font color.
The display mode may include specific content to be displayed, as well as a rotation mode, a font size, a font color of the content to be displayed, and the like. The rotation mode means that when the display screen of the medical device is unable to display all of the contents to be displayed at once, the contents to be displayed may alternately appear on the display screen according to a preset rotation mode. For example, if the contents to be displayed include an infusion rate and an infusion volume, the rotation mode might be that the infusion rate and the infusion volume are alternately scrolled on the display. Alternatively, a rotation character bar may also be preset, and the rotation character bar may be a separator between different contents to be displayed. For example, the rotation character bar may be “|”, and if the contents to be displayed are the infusion rate and the infusion volume, then the infusion rate and the infusion volume may be separated by “|”.
The distance between the target and the medical device can be determined in real time, and the display mode can be changed in real time according to the distance between the target and the medical device. For example, a font size of the content to be displayed may become smaller as the target approaches and larger as the target moves away.
The beneficial effect of this setting is that the content to be displayed and the display mode are adjusted in real time according to the distance between the target and the medical device, so that the medical device can carry out the display in a timely manner and display the content required by the target, and the display efficiency and accuracy of the medical device are improved. The target can clearly view the medical device from a distance and improve the viewing experience of the target.
In this embodiment, the medical device includes a first device and a second device; determining the content to be displayed by the medical device based on a distance between the target and the medical device, comprising: if the distance between the target and the first device is obtained, determining the content to be displayed on the second device based on the distance between the target and the first device.
Patients may sometimes use multiple medical devices at the same time, and medical staff need to check the use of multiple medical devices during ward rounds. For example, if a patient is using an infusion pump and a ventilator at the same time, the medical staff needs to maintain a certain distance from the patient to check the infusion rate displayed by the infusion pump and the respiratory rate displayed by the ventilator. As another example, if a patient is using more than one infusion pump at the same time, the medical staff needs to obtain data, such as the infusion rate and infusion drug, displayed by each infusion pump.
If a patient is using two medical devices at the same time, one of the medical devices is the first device and the other medical device is the second device. If the patient is using three or more medical devices at the same time, one of the medical devices is the first device, and the other medical devices are the second device. The first device is the medical device that first determines the presence of the target within its preset range. For example, if the medical staff is approaching the patient, and the medical staff is oriented directly to the infusion pump, and the infusion pump is the first to recognize the target, then the infusion pump may be the first device, and the other medical devices are the second devices. The first device and the second device of the plurality of devices may also be preset.
The first device determines a distance between the target and itself after determining that the target is present within a preset range. Based on the distance between the target and the first device, content to be displayed by the first device is determined. Both the second device and the first device serve the same patient, and the first device and the second device are located in the same ward. After obtaining the distance between the target and the first device, the distance between the target and the first device can be used as the distance between the target and the second device, so as to determine the content to be displayed on the second device. That is, the content to be displayed for the second device is determined based on the distance between the target and the first device.
The beneficial effect of this setting is that according to the distance obtained by one medical device, the content to be displayed of all other medical devices can be dynamically adjusted. When the font of the content to be displayed on the first device becomes larger, the font of the content to be displayed on the second device may also become larger. This setting can simplify the process of recognition of the target by the second device, improving the display efficiency of the medical device, and thus improving the viewing efficiency of the user.
Multiple medical devices can also individually determine whether a target is present within a preset range, and determine the distance between the target and each medical device. Distances determined by each medical device can be verified, for example, each medical device may obtain the distances determined by the other medical devices, and determine whether the difference between the distances is within a preset difference range. If a medical device determines that among the distance differences between itself and the other medical devices, there is a distance difference that lies within the preset difference range, then the medical device may determine its own content to be displayed according to the distance determined by itself. If a medical device determines that the distance differences between itself and other medical devices are not within the preset difference range, then it considers that the distance obtained by itself is erroneous. In this case, the identification of the target and the determination of the distance can be repeated, or the distance obtained by other medical devices can be used as the distance between the medical device and the target. This enables the adjustment of the distance and improves the accuracy of the display. For example, assume there are three medical devices, device one, device two, and device three. Each medical device determines distance differences between the distance obtained by itself and the distances obtained by the other two medical devices. Assume further that the distance difference between device one and device two is within the preset difference range; the distance difference between device two and device three is not within the preset difference range; and the distance difference between device one and device three is not within the preset difference range. It can be assumed that the distance obtained by device three is erroneous, and device three can re-determine the distance, or use the distance obtained by device one or device two as the distance for device three, to improve the accuracy of the content display of device three.
S103, the content to be displayed is displayed on a display interface of the medical device.
For example, a display screen may be arranged on the medical device for displaying a display interface from which the content to be displayed is displayed. After the content to be displayed is determined, the data of the content to be displayed can be displayed on the display interface of the medical device according to a display manner. For example, the information may be displayed according to a preset font size and font color. As the target moves, the content to be displayed on the display interface may change. For example, the display font may become larger as the target is away from the medical device.
This embodiment of the invention provides a display method applied to the medical device, by determining whether a target is present within a preset range of the medical device, and if so, measuring a distance between the target and the medical device. Content to be displayed for the medical device is adjusted according to the distance. The content to be displayed is displayed on a screen of the medical device for viewing by the target. The invention solves the problems in the prior art that the user can only manually operate the medical device to display the content of the medical device, which causes low display efficiency and the like. It realizes automatic adjustment of the display content and improves display efficiency. Adjusting the display content according to the distance between the target and the medical device makes it possible for the target to view the treatment of the patient from a distance, so that the target can maintain a certain distance from the patient, ensure the safety of the target, and improve the target's viewing efficiency of the content displayed on the medical device.
In this embodiment, if it is determined that a target is within a preset range of the medical device, then the system determines a distance between the target and the medical device, which may be refined as follows: identifying a user within the preset range of the medical device as the target, if the user within the preset range of the medical device is detected according to a target detection device arranged on the medical device. The target detection device includes one or more of these devices, which may be a millimeter wave radar, an infrared sensor, an ultrasonic sensor, or an image acquisition device. Based on the target detection device, a distance between the target and the medical device is measured.
As shown in
S301, based on the target detection device arranged on the medical device, if it is determined that a user is present within a preset range of the medical device, the user will be considered as a target; and the target detection device may include one or more of these devices, which may be a millimeter wave radar, an infrared sensor, an ultrasonic sensor or an image acquisition device, and the image acquisition device may be a camera and the like.
As one example, one or more target detection devices may be arranged on the medical device, for example, the target detection device may include one or more of these devices, which may be a millimeter wave radar, an infrared sensor, an ultrasonic sensor or an image acquisition device, and the image acquisition device may be a camera and the like.
The medical device may detect whether a target is present within the preset range in real time or at regular intervals by its own target detection device. For example, the target detection device determines whether a user is present within the preset range of the medical device, and if so, the user, which is located within the preset range, is determined to be the target. If the target detection device is a millimeter wave radar, based on the millimeter wave radar, millimeter-wave transmission and reception can be performed within the preset range to determine whether a user is present. If the target detection device is an infrared sensor, based on the infrared sensor, detecting whether infrared heat corresponding to a human body is present within the preset range, thereby, it can be determined whether a user is present within the preset range. If the target detection device is an ultrasound sensor, based on the ultrasonic sensor, then ultrasonic waves are sent and received within the preset range to determine whether a user is present within the preset range. If the target detection device is an image acquisition device, based on the image acquisition device, an image or a video within the preset range can be acquired, and by means of a preset target recognition algorithm, whether a user is present in the image or the video can be determined.
The identification condition for the target may be set in advance, and after determining that a user is present within a preset range of the medical device according to the target detection device arranged on the medical device, identifying information for the user is obtained, and determining whether the identifying information for the user satisfies the preset identification conditions, and if so, determining that the user is the target; if not, determining that the user is not the target. The identification information may be information identifying whether the user is the target, for example, it may be identity information of the user, or it may be information such as how long the user is located within the preset range, that is the user's “dwell time”, and the identity information may be information such as a human face. For example, if the preset identification condition is that the medical device will display content only when a specific medical staff member enters the preset range, the identity information of the user in the preset range can be obtained to determine whether the user is a predetermined specific medical staff, and thus whether the user is the target.
In this embodiment, if it is detected that a user is present within a preset range of the medical device, based on the target detection device arranged on the medical device, the user may be considered as a target. The method of operation then comprises: if it is detected that a user is present within a preset range of the medical device, based on the target detection device arranged on the medical device, obtaining a dwell time of the user within the preset range; and determining that the user is a target if the dwell time is more than a preset time threshold.
Specifically, if a user, such as a medical staff member, just passes by the ward, there is no need to change the display interface of the medical device at this time. The user needs to stay within a preset range of the medical device for a certain period of time to trigger the medical device to carry out the determination of the target, and the time can be set according to the actual needs.
Whether a user is present within the preset range is detected by the target detection device, and if so, the dwell time of the user within the preset range is determined. For example, the presence of a user within the preset range may be detected by the video captured by the camera. A point in time at which the user appears in the video and a point in time at which the user disappears from the video are determined to obtain the dwell time of the user. A time threshold is preset, the dwell time is compared with the preset time threshold, and if the dwell time exceeds the preset time threshold, the user is determined to be the target; and if the dwell time does not exceed the preset time threshold, the user is determined not to be the target. If there a plurality of users are located within the preset range whose dwell times all exceed the preset time threshold, the distance between each user and the medical device is detected and the user closest to the medical device is identified as the target.
The beneficial effect of such a setting is that by performing a comparison of the dwell time, it avoids mistaking a passing user for the target, reduces the occurrence of a misrecognition situation, improves the detection accuracy of the target, avoids frequent content display by the medical device, and improves the display efficiency and precision of the medical device.
In this embodiment, if a user is detected within a preset range of the medical device, based on the target detection device arranged on the medical device, the user will be considered as a target. The method of operation then comprises: if a user is detected within a preset range of the medical device, based on the target detection device arranged on the medical device, a distance change between the user and the medical device is determined, and if it is determined that the distance change between the user and the medical device satisfies a preset change state, the user is determined to be a target.
Specifically, based on a target detection device arranged on the medical device, it is determined whether a user is present within a preset range of the medical device, and if so, a movement trajectory of the user is detected to obtain a distance change between the user and the medical device. The distance change means that the user is getting closer to or farther away from the medical device. For example, if the target detection device is an infrared sensor, the distance change between the user and the medical device can be determined by the size of the infrared imaging surface. If the infrared imaging surface is becoming larger, the distance change is determined as getting closer; if the infrared imaging surface is becoming smaller, the distance change is determined as getting farther away. As another example, if the target detection device is a millimeter wave radar, the distance change between the user and the medical device can be determined by the size of the reflected surface of the millimeter wave. If the reflective surface becomes larger, the distance change is determined as getting closer; if the reflective surface becomes smaller, the distance change is determined as getting farther away. The distance change between the user and the medical device can also be determined by, for example, image recognition by a camera.
A change condition is preset, and the preset change condition may be that the distance change is getting closer. If it is determined that the distance change between the user and the medical device satisfies the preset change condition, that is, it is determined whether the distance change between the user and the medical device is getting closer, then the user is determined to be the target; if the distance change between the user and the medical device is getting farther away, it is determined that the user is not the target.
If there are a plurality of users within the preset range, the user who is approaching the medical device may be determined as the target based on the distance changes corresponding to the plurality of users. If there is a plurality of users who are approaching the medical device, a distance between each of the users and the medical device can be determined, and the closest of these users to the medical device can be identified as the target.
The beneficial effect of such a setting is that a target detection device on the medical device, such as a sensor, can detect a change in the relative position of the user within a preset range, and when the user is sensed as being approaching, the target can be determined in advance, which facilitates the timely adjustment of the content to be displayed, and improves the efficiency and precision of the display.
In this embodiment, assume that at least two users are present within a preset range of the medical device; if it is determined that a user is present within the preset range of the medical device according to the target detection device arranged on the medical device, the system determines that the user is a target. This method then comprises: measuring an orientation angle of each user relative to the medical device; and determining that the user as a target if the orientation angle of the user satisfies a preset angle condition.
Specifically, the target detection device on the medical device may measure an orientation angle of the user relative to the medical device, that is, it may determine whether the user is facing the medical device. For example, an infrared imaging surface size may be determined by an infrared sensor, a size threshold of the infrared imaging surface may be predetermined, and if the size of the infrared imaging surface exceeds the preset size threshold of the infrared imaging surface, it may be assumed that the user is facing the medical device; or a reflective surface size may be determined by millimeter wave radar, a size threshold of the reflective surface may be preset, and if the size of the reflective surface exceeds the preset size threshold of the reflective surface, it may be assumed that the user is facing the medical device. It may also be recognized by the camera whether the user is facing the medical device. If the user is facing the medical device, the user's orientation angle may be determined to be 180 degrees.
If an angle condition is preset, for example, the angle condition may be an range of the user's orientation angle toward the medical device, and if the user's orientation angle toward the medical device is within a preset angular range, the user may be considered to be facing the medical device, such that the user is considered to be the target.
A plurality of users may be located within a preset range of the medical device. If a plurality of users are present, an orientation angle of each user toward the medical device may be detected. Whether each orientation angle is within the preset angle range is determined, that is, it is determined whether each orientation angle satisfies the preset angle condition. If so, then the user corresponding to the orientation angle is considered as the target. An angle threshold may be preset, and if a plurality of orientation angles are detected within the preset angle range, a difference between the orientation angles located within the angle range and the angle threshold is determined, and the user corresponding to the orientation angle with the smallest difference is identified as the target, that is, the user corresponding to the orientation angle that is closest to the angle threshold is identified as the target. If a plurality of orientation angles are located within the predetermined angle range, a distance between the user whose orientation angle located within the angle range and the medical device may also be measured, and the user with the smallest distance is considered as the target.
The beneficial effect of such a setting is that when there is a plurality of users are within a preset range, the optimal user facing the medical device can be determined by means of the size of the infrared imaging surface, the size of the reflective surface, the camera identification and the like, so as to carry out a content display for the user, and to improve the precision and efficiency of the display.
In this embodiment, one or more users may be located within a preset range of the medical device, and if it is determined that only one user is present within the preset range of the medical device based on the target detection device arranged on the medical device, an orientation angle of the user toward the medical device may be measured; if the orientation angle of the user satisfies the preset angle condition, the user is considered to be the target; and if the orientation angle of the user does not satisfy the preset angle condition, the user is not the target. That is, for each user within the preset range, the user's orientation angle can be measured, and even if only one user is present within the preset range, the target may not be present, realizing that the medical device can accurately determine the target, display the content for the target, and effectively improve the display accuracy.
In this embodiment, at least two users are present within a preset range of the medical device; if it is determined that a user is present within the preset range of the medical device based on the target detection device arranged on the medical device, the user located within the preset range of the medical device is considered to be the target. The method in this embodiment comprises: based on the pre-arranged image acquisition device, acquiring a face image of each of the users; and determining the user to be a target if the face image of the user is stored in a preset face image library.
Specifically, the medical device may be arranged with an image acquisition device, such as a camera, and the medical device may acquire a facial image of a user within a preset range by means of the image acquisition device. A human facial image library is pre-stored in the medical device, and facial information of the preset user is stored in the human facial image library, for example, facial information of a medical staff member is stored in the human facial image library. After obtaining the facial image of the user, it is determined whether the facial image of the user is stored in the facial image library, and if so, it is determined that the user has the permission to view the medical device, and that the user is the target; if not, it is determined that the user does not have the permission to view the medical device, and that the user is not the target.
A plurality of users may be located within a preset range of the medical device, and if a plurality of users are present, a facial image of each of the users may be acquired. The system then determines whether or not each of the facial images is located in the facial image library, and the user corresponding to the facial image located in the facial image library is considered as a target. If there are a plurality of users whose facial images are all located in the face image library, the plurality of users located in the facial image library are determined as candidate targets. The distance between each candidate target and the medical device is then determined, and the closest candidate target is identified as the target.
The beneficial effect of such a setting is that by performing facial recognition, it can be ensured that only professionals can view the medical device, avoiding misrecognition and information leakage, and improving the efficiency and precision of content display.
In this embodiment, one or more users may be located within a preset range of the medical device, and if it is detected that only one user is present within the preset range of the medical device based on the target detection device arranged on the medical device, a facial image of the user may be acquired based on the pre-arranged image acquisition device; if the facial image of the user is stored in the preset facial image library, the user is determined to be the target. If the facial image of the user is not in the preset facial image library, it is determined that the user is not the target. That is, for each user within the preset range, the facial image of the user can be determined without limit of the number of people. Even if only one user is present within the preset range, the target may not be present, realizing that the medical device can accurately determine the target and display the content for the target, further improving the display accuracy.
A medical device may be pre-arranged with a plurality of target detection devices, for example, the medical device may have both an infrared sensor and a camera. A multi-sensor fusion can be used to determine whether a user within a preset range is a target.
In this embodiment, the target detection device on the medical device may include a first detection device and a second detection device. Based on the target detection device arranged on the medical device, if it is determined that a user is present within a preset range of the medical device, the user who is present within the preset range of the medical device is determined to be the target. The method according to this embodiment comprises: based on the first detection device arranged on the medical device, determining whether a user is present within a predetermined range of the medical device; if so, determining whether the user satisfies a preset confirmation condition based on the second detection device arranged on the medical device; and if so, the user is considered as a target.
Specifically, the first detection device may be a target detection device for detecting a distance between the user and the medical device, and the second detection device may be a target detection device other than the first detection device. By means of the first detection device, the distance between the user and the medical device may be detected to determine whether the user is within a preset range of the medical device. If not, no further target determination is required for the user; if so, by the second detection device, it is determined whether the user satisfies the preset confirmation condition. If it is satisfied, it is determined that the user is the target; if it is not satisfied, it is determined that the user is not the target. The confirmation condition may be determined according to the second detection device. For example, if the second detection device is a camera, the confirmation condition may be that the facial image of the user is located in a pre-stored facial image library; or, if the second detection device is an infrared sensor, the confirmation condition may be that the user's facing angle is within the preset angle range. That is, the distance between the user and the medical device may be judged first, and the recognition of the facial image may be initiated after the distance satisfies the condition of the preset range; or, the distance between the user and the medical device may be judged first, and the orientation angle of the user may be judged after the distance satisfies the condition of the preset range.
Three or more target detection devices may also be arranged on the medical device, whereby the user is determined to be the target only after the user satisfies the confirmation conditions of all the target detection devices. For example, a distance between the user and the medical device may first be determined, and if the distance is within the preset range, then a facial image of the user is acquired, and if the facial image of the user is stored in a preset facial image library, a facing angle of the user is acquired. If the user's facing angle is within the preset angle range, the user is determined to be the target. The present embodiment does not specifically limit the order of evaluation of each condition.
The beneficial effect of such a setting is that, by means of multi-sensor fusion, precise determination of the target can be realized, avoiding identifying a passing user or a user without authority as the target, improving the precision of determination of the target, and thus improving the display precision of the medical device.
S302, based on the target detection device, the distance between the target and the medical device is determined.
As one example, after determining the target, a distance between the target and the medical device is measured based on the target detection device. For example, a coordinate position of the target in an image may be determined by a camera, and based on the coordinate position, the distance between the target and the medical device may be calculated. Different target detection devices may be used to determine the distance in different ways. The invention is not limited to any specific way of determining the distance.

As one example, this step can be referred to the above step S102 and not be repeated.
S304, the content to be displayed is displayed on a display interface of the medical device.
As one example, this step may be referred to the above step S103, and not be repeated.
The invention provides a display method for a medical device, by determining whether a target is present within a predetermined range of the medical device, and if so, determining a distance between the target and the medical device. Content to be displayed by the medical device is adjusted according to the distance. The content to be displayed is displayed on a screen of the medical device for viewing by the target. The invention solves the problems in the prior art that the user can only manually operate the medical device to display the content of the medical device, which causes low display efficiency and the like. It provides automatic adjustment of the display content and improves display efficiency. Adjusting the display content according to the distance between the target and the medical device makes it possible for the target to view the treatment of the patient from a distance, so that the target can maintain a certain distance from the patient, ensure the safety of the target, and improve the target's viewing efficiency of the content displayed on the medical device.
