This application claims priority to Chinese patent Application No. 202210168566.X, filed on Feb. 23, 2022, the content of which is incorporated herein by reference in its entirety.
The disclosure relates to the technical field of medical device, and more particularly to an anesthesia machine, an anesthesia control method and an anesthesia control system.
In traditional anesthesia process, doctors need to operate an anesthesia machine and an injection pump respectively to complete ventilation maintenance and anesthesia control during surgery. The anesthesia machine is connected with airway of a patient through a respiratory pipeline to deliver a gas with certain pressure and flow rate to the patient to maintain oxygenation of the patient. At the same time, it can also deliver anesthetic gas of a certain concentration. The injection pump is connected with a vein channel of the patient through an infusion pipeline, and delivers a variety of medications to the patient at a certain rate, including sedatives, analgesics, muscle relaxants, vasoactive drugs, etc. In order to maintain the stability of vital signs of the patient during the surgery, the doctor needs to observe monitoring parameters of the vital signs of the patient, and then turn to the anesthesia machine to adjust inhalation of anesthetic and ventilation, or turn to the injection pump to adjust intravenous medication. The doctor switches the workflow between multiple devices, which affects the efficiency and increases the potential risk of misjudgment and mis-operation.
However, positions of the devices in the operating room are not fixed, which increases the complexity of the workflow of the doctor. The anesthesia machine is usually fixed near head of the patient to facilitate the connection of the ventilation pipeline, while the monitor is generally placed next to the anesthesia machine, and the injection pump may be placed at different positions at a body side of the patient according to the different types of surgery. When the injection pump and the anesthesia machine are not in the same place, the doctor needs to move back and forth in the operating room to complete the anesthetic process of monitoring and adjustment. The space in the operating room is generally very crowded, and frequent movement may affect the operation.
Therefore, the efficiency of the existing anesthesia control needs to be improved.
In this regard, an anesthesia machine, an anesthesia control method and an anesthesia control system, are provided, aiming at improving the efficiency of anesthesia control.

The following is a detailed description through several embodiments.
As shown in
The anesthetic delivery device 220 is configured to mix a gas provided by a gas source with an anesthetic and deliver the mixed gas to the respiratory line. The gas source is configured to provide the gas required by the anesthesia machine, such as oxygen, air and nitrous oxide (laughing gas), etc. The gas source can be external, such as various gas cylinders, hospital pipes, etc., or also be internal, such as a turbine. The anesthetic delivery device 220 can use an evaporator.
The respiratory line 230 can be a gas line which connects the anesthetic delivery device 220 and a patient. It can recycle the gas exhaled by the patient to save the anesthetic and reduce environmental pollution. The respiratory line 230 can further include various connection tubes and accessories which can be a nose plug, nose mask, face mask, tracheal tube with a bag at its end, etc. The respiratory line 230 can be provided with a gas purification device for removing at least part of carbon dioxide exhaled by the patient into the respiratory line 230.
The processor 210 is configured to control the respiratory line 230 to periodically deliver the mixed gas to the patient, thus providing anesthesia respiratory support for the patient. For example, the respiratory line 230 is provided with a plurality of valves, and the processor 210 can periodically deliver the mixed gas to the patient through controlling the plurality of valves, so as to provide anesthesia respiratory support for the patient.
The communication module 240 is configured to communicate with other devices in the system, such as the infusion device 30 and the control terminal. The communication module 240 can include a communication interface, which is connected with the infusion device 30 or the control terminal through a cable to realize the communication connection. The communication module 240 can also be a wireless transmission module (that is, a wireless communication module), such as a WIFI module, a WLAM module, a Bluetooth module, and the likes. The wireless transmission module is connected with the infusion device 30 or the control terminal through wireless communication connection.
The human-machine interaction device 250 is for human-machine interaction, for example, it can be configured to output visual information, or receive user input. The human-machine interaction device 250 can use an input apparatus to receive user input, such as keyboard, operation button, mouse, trackball, touch pad, microphone, or touch screen integrated with the display, etc. The human-machine interaction device 250 can output visual information by using displayers, such as various types of displayers.
In an embodiment, as shown in
The processor 210 is further configured to receive anesthesia machine control information which is inputted by the user through the human-machine interaction device 250, for example, to receive the anesthesia machine control information which is inputted by hand or voice of the user through the human-machine interaction device 250, and to control ventilation of the patient according to the anesthesia machine control information. The human-machine interaction device 250 is further configured to receive infusion device control information which is inputted by the user through the human-machine interaction device 250, for example, to receive the infusion device control information which is inputted by hand or voice of the user through the human-machine interaction device 250, and to send a corresponding infusion device control instruction to the infusion device 30 through the communication module 240, wherein the infusion device control instruction is configured to control the infusion device 30 to administer medication to the patient.
The infusion device 30 may include only one injection pump, or multiple (two or more) injection pumps. The infusion device 30 also has a communication module for communicating with the anesthesia machine 20 or the control terminal. The communication module of the infusion device 30 can also be a communication interface or a wireless transmission module. When multiple injection pumps are needed in the surgery, each injection pump can be provided with a separate wireless transmission module (as shown in
The process of anesthesia control by the anesthesia control system is shown in
In step 1, communication connection is established between the anesthesia machine 20 and the infusion device 30. The anesthesia machine 20 is connected with the infusion device 30 via wired communication or wireless communication, which can be connected through the LAN. This example takes the wireless communication connection between the two as an example to illustrate. The wireless communication connection requires no cable, the placement of the device is more flexible, and the medical staff does not need to pay attention to the interference of cable during the surgery. The infusion device 30 also has a communication module. This embodiment also takes the wireless transmission module as an example. The wireless transmission module of the anesthesia machine 20 and the wireless transmission module of the infusion device 30 are responsible for establishing data connection between the two. Specifically, the wireless transmission modules of the two devices are paired, and the data connection is established if the pairing is successful.
After the anesthesia machine 20 establishes the wireless communication connection with the infusion device 30, it indicates that a wireless communication connection has been established with the infusion device 30. For example, the anesthesia machine 20 sends first connection indication information to indicate that the wireless communication connection has been established with the infusion device 30. The first connection indication information can be sound indication, light indication, vibration indication, or text and graphic indication on a display interface of the displayer. After the anesthesia machine 20 establishes the wireless communication connection with the infusion device 30, the processor 210 also displays which device is currently connected through the displayer, that is, the processor 210 displays identification of the infusion device 30 which is connected by wireless communication. The identification of the infusion device 30 can be ID, icon or number of the infusion device 30.
Of course, after the infusion device 30 establishes the wireless communication connection with the anesthesia machine 20, it can also indicate that the wireless communication connection has been established with the anesthesia machine 20. For example, the infusion device 30 sends second connection indication information to indicate that the wireless communication connection has been established with the anesthesia machine 20. The second connection indication information can be sound indication, light indication, vibration indication, or text and graphic indication on the display interface of the displayer. After the infusion device 30 establishes the wireless communication connection with the anesthesia machine 20, the displayer of the infusion device 30 also displays which device is currently connected, that is, displays identification of the anesthesia machine 20 which is connected by wireless communication. The identification of the anesthesia machine 20 can be ID, icon or number of the anesthesia machine 20.
In step 2, the anesthesia machine 20 controls ventilation of the patient according to anesthesia machine control information which is inputted by the user. For example, the anesthesia machine 20 controls the ventilation of the patient according to the anesthesia machine control information which is inputted by hand and/or the anesthesia machine control information which is inputted by voice. That is, the user controls the anesthesia machine 20 through the human-machine interaction device 250, and then controls the ventilation of the patient. This embodiment takes the anesthesia machine control information which is inputted by hand of the user as an example for explanation. Specifically, the display interface of the displayer of the anesthesia machine 20 displays an anesthesia machine setting area for receiving the anesthesia machine control information which is inputted by the user. In the anesthesia machine setting area, users can set ventilation control parameters (including ventilation mode, tidal volume or inspiratory pressure, respiratory rate, I:E ratio or inspiratory time, trigger sensitivity, etc.), flowmeter parameters (including oxygen flow, air flow, laughing gas flow, or total flow, oxygen concentration, etc.), electronic evaporator settings (including evaporator selection, output drug concentration, etc.), special function operation (such as inhalation holding, exhalation holding, pulmonary re-expansion), etc. The display interface of the displayer of the anesthesia machine 20 also has an anesthesia information display area, which can display ventilation waveforms (including flow rate, pressure, volume, etc.), ventilation monitoring parameters (including inspiratory/expiratory tidal volume, inspiratory/expiratory minute ventilation volume, respiratory rate, platform pressure, peak pressure, positive end-expiratory pressure, etc.), gas monitoring parameters (inhaled/exhaled anesthetic gas concentration, inhaled/exhaled oxygen concentration, inhaled/exhaled CO2 concentration, inhaled/exhaled N2O concentration, etc.). The user can set the anesthesia machine control information in the anesthesia machine setting area based on the displayed information and condition of the patient, so as to control the ventilation of the patient.
In step 3, the anesthesia machine 20 sends a corresponding infusion device control instruction to the infusion device 30 according to infusion device control information which is inputted by the user. For example, the anesthesia machine 20 sends the corresponding infusion device control instruction to the infusion device 30 according to the infusion device control information which is inputted by hand and/or the infusion device control information which is inputted by voice. That is, the processor 210 receives the infusion device control information through the human-machine interaction device 250, then generates the corresponding infusion device control instruction according to the infusion device control information, and sends the corresponding infusion device control instruction to the infusion device 30 through the communication module 240, thus controlling the infusion device 30.
This embodiment takes the infusion device control information which is inputted by hand of the user as an example for explanation. Specifically, the display interface of the displayer of the anesthesia machine 20 displays an infusion device setting area for receiving the infusion device control information which is inputted by the user. In the infusion device setting area, the user can select an active injection pump and set its medication name, medication concentration, injection mode (such as TCI mode, speed mode, body weight mode, etc.), and set injection parameters (such as target control object and target control concentration in TCI mode, injection flow rate in speed mode, waiting volume, etc.). The display interface of the displayer of the anesthesia machine 20 also has an injection information display area. The injection information display area can display an amount of injection, amount to be injected, flow rate, plasma concentration, effect chamber concentration, etc. The user can control the infusion device by setting the infusion device control information in the infusion device setting area based on the displayed information and condition of the patient.
Among them, the anesthesia machine setting area and the infusion device setting area may not appear on the same display interface (interactive interface), that is, the two areas can be displayed on different display interfaces of the anesthesia machine, or can be displayed on the same interface of the anesthesia machine, that is, the two areas can be displayed on the same display interface at the same time. The latter is explained as an example. Users can adjust the parameters of anesthesia machine 20 and infusion device 30 on the same interactive interface, without operating separately on the two devices or walking between the two devices, which improves the work efficiency and safety. Similarly, the anesthesia information display area and the injection information display area may not appear on the same display interface, and may also be displayed on the same interface of the anesthesia machine. The latter is explained as an example in this embodiment. In this embodiment, in order to understand completely and control the situation of the patient, the anesthesia machine setting area, the infusion device setting area, the anesthesia information display area and the injection information display area are displayed on the same display interface. Of course, in some embodiments, various types of physical keys can be configured to replace virtual keys in the anesthesia machine setting area and the infusion device setting area for the user to input control information.
Before the processor 210 sends the corresponding infusion device control instruction to the infusion device 30 through the communication module 240, it can also determine whether information of the patient in the anesthesia machine 20 is consistent with information of the patient in the infusion device 30. If yes, the processor 210 sends the corresponding infusion device control instruction to the infusion device 30 through the communication module 240. Or else, the processor 210 indicates that there is a problem. For the sake of safety, the processor 210 disconnects the wireless communication connection, that is, disconnects the wireless communication connection with the infusion device 30 through the communication module 240, and also refuses to send the infusion device control instruction, and/or sends an alarm massage, such as outputting first alarm information, which can be sound indication, light indication, vibration indication, or text and graphic indication on a display interface of the displayer, to warn the user that the information of the patient is currently abnormal.
In step 4, the infusion device 30 receives the infusion device control instruction from the anesthesia machine 20, and controls medication administration to the patient according to the infusion device control instruction. It can be seen that the medical staff can control the anesthesia machine 20 and the infusion device 30 only by operating the anesthesia machine 20, which is very convenient and efficient.
In the embodiment shown in
In the embodiment shown in
The infusion device 30 indicates that the infusion device control instruction has been received after receiving the infusion device control instruction. For example, the infusion device 30 sends first receiving indication information to indicate that the infusion device control instruction has been received. The first receiving indication information can be one or more of the following: sound indication (such as indication tone), light indication (such as flashing LED light, color change of all or part of the screen of the infusion device 30), vibration indication, identification indication of screen display state of the infusion device 30 (such as text, graphics), etc. The infusion device 30 feeds back the first receiving indication information to the user, which is convenient for the user to confirm that the infusion device 30 has received the control instruction, thus improving the safety of operation.
In the system provided by this disclosure, after the injection pump and the anesthesia machine have successfully established a wireless connection, the anesthesia machine can pop up an indication message of successful connection, and the injection pump can also send an indication message of successful connection. When the user sets control parameters of the injection pump on the interactive interface, the injection pump also sends a corresponding indication message to remind the user that it has received the control parameters after receiving these control parameters. Accordingly, the user can understand completely each step according to the indication messages, which improves the security.
Before the infusion device 30 can determine whether information of the patient to whom the infusion device 30 administers medication is consistent with information of the patient whose ventilation is controlled by the anesthesia machine 20, before the controlling medication administration to the patient according to the infusion device control instruction. If yes, the infusion device 30 can control the medication administration to the patient according to the infusion device control instruction. Or else, the infusion device 30 disconnects the wireless communication connection, that is, disconnects the wireless communication connection with the anesthesia machine 20, and also refuses to receive or respond to the infusion device control instruction, and/or sends an alarm massage, such as outputting second alarm information, which can be sound indication, light indication, vibration indication, or text and graphic indication displayed on the screen, to warn the user that the information of the patient is currently abnormal.
The infusion device 30 also provides an option for whether to accept remote control for the user to set. For example, when the user decides that the infusion device 30 can accept remote control, the user can operate the infusion device 30 to send an instruction to start a remote control function (such as selecting the option of accepting remote control). At this time, the infusion device 30 can receive a remote control instruction and execute it, such as allowing to receive the infusion device control instruction or to respond to the infusion device control instruction. When the user does not want this infusion device 30 to accept the remote control, the user can operate the infusion device 30 to send an instruction to close a remote control function (such as cancelling selection of the option of accepting remote control). The infusion device 30 receives the instruction to close the remote control function, and responds to said instruction by stopping receiving the infusion device control instruction or by stopping responding to the infusion device control instruction. That is, the infusion device 30 is no longer controlled by the anesthesia machine 20, which can avoid subsequent mis-operation.
The infusion device 30 can also determine whether the patient is changed, and process the workflow which is restarted after its standby according to the determination result of whether the patient is changed.
For example, the infusion device 30 includes a first injection pump. Anesthesia machine 20 has three working states: output state (outputting anesthetic to the patient), no-output state (not outputting anesthetic to the patient) and standby state (such as, opening a gripper of injection pump). When the first injection pump is in the no-output state or standby state, the working state of the anesthesia machine 20 is acquired. The first injection pump updates the information of the patient of the first injection pump at least based on the acquired working state of the anesthesia machine 20 before starting injection. Specifically, if the acquired working state of the anesthesia machine 20 is the output state, it means that the first injection pump is in the no-output state or the standby state temporarily, and then it continues to give medication to the original patient when it enters the output state. That is, it is not necessary to input information of patient again after the first injection pump restarts to output. If the acquired working state of anesthesia machine 20 is no-output state or standby state, it can be considered that the infusion device 30 and anesthesia machine 20 have completed the work for the current patient. After the first injection pump restarts to output (the next time it enters the output state), it is necessary to update information of the patient in the first injection pump, and after the anesthesia machine 20 restarts to output, it is also necessary to update the information of the patient.
As another example, the infusion device 30 includes a first injection pump and a second injection pump. The injection pump has three working states: output state (injecting medication to the patient), no-output state (not injecting medication to the patient) and standby state (such as, opening a gripper of injection pump). When the first injection pump is in no-output state or standby state, the working state of the second injection pump is acquired. Before the first injection pump starts to inject, information of the patient in the first injection pump is updated at least based on the acquired working state of the second injection pump. In this embodiment, the first injection pump acquires the working state of other controlled devices (such as the second injection pump and anesthesia machine). Before the first injection pump starts to inject, information of the patient in the first injection pump is updated based on the acquired working state of other controlled devices. Specifically, if the acquired working state of the second injection pump is in the output state, it means that the first injection pump is in the no-output state or the standby state temporarily, and then it continues to give medication to the original patient when it enters the output state. That is, it is not necessary to input information of patient again after the first injection pump restarts to output. If the acquired working state of second injection pump is no-output state or standby state, the working state of the other injection pumps (if any) of the infusion device 30 can also be acquired. If the other injection pumps are also in the no-output state or standby state, it can be considered that the infusion device 30 has completed the work for the current patient. After the first injection pump restarts to output (the next time it enters the output state), it is necessary to update information of the patient in the first injection pump. If multiple injection pumps are used for intravenous administration during the surgery, when the gripper of any injection pump is opened, there are still other injection pumps continuing to inject. At this time, it can be determined that the injection pump with the opened gripper only needs to replace medication, and the replaced medication can still be administered according to the information of the previous patient. In this way, there is no need for users to input or confirm the information of the patient before each injection. If all controlled devices of different types enter the standby state or enter the no-output state during the surgery, such as the ventilation model of the anesthesia machine cannot be monitored, and the injection pump enters the standby state, then it can be determined that the anesthesia of the last patient has ended, and the information of the patient needs to be re-inputted when the next ventilation or injection is restarted.
When the anesthesia machine 20 is in the no-output state or standby state, the working state of the infusion device 30 can also be acquired. The anesthesia machine 20 updates the information of the patient of the anesthesia machine at least based on the acquired working state of the infusion device 30 before starting ventilation. Specifically, if the acquired working state of the infusion device 30 is in the output state, it means that the anesthesia of the patient is not over, and the anesthesia machine 20 continues to give anesthetic to the original patient when it enters the output state, that is, the anesthesia machine 20 does not need to re-input the information of the patient after restarting to output. If the acquired working state of infusion device 30 is in the no-output state or standby state, it can be considered that the infusion device 30 and anesthesia machine 20 have completed the work for the current patient, and the anesthesia machine 20 needs to update the information of the patient after restarting to output.
To sum up, this disclosure integrates the control of anesthesia machine and injection pump, and sends user instruction through remote transmission, which can solve the problem of complex workflow of doctor and the need to switch and operate multiple devices. For remote transmission, although the traditional wired connection can solve the need for centralized control, when the anesthesia machine and injection pump are placed at different sides of the patient, the connection cable may invade the work area of the doctor and cause potential risks. Therefore, wireless connection is the most ideal connection mode, which can realize the centralized control of anesthesia machine and injection pump without introducing additional cable management risks. However, the wireless connection mode may introduce the risk of misoperation. There are usually multiple anesthesia machines and injection pumps in multiple adjacent operating rooms. Inadvertent operation may connect the devices in different operating rooms, which results in that setting instructions of the doctor are sent to unexpected device, thus causing improper medication administration. This disclosure avoids the risk of connecting devices in different operating rooms through wireless pairing, indicating after successful pairing, and indicating after that the controlled device receives the instruction, which improves the efficiency of anesthesia control while ensuring safety.
The above steps 2 and 3 are for the user to set various parameters of the anesthesia machine and infusion device on the display interface of the anesthesia machine. In some embodiments, the anesthesia machine can generate corresponding infusion device control instruction according to the anesthesia machine control information. As shown in
In step 1′, communication connection is established between the anesthesia machine 20 and the infusion device 30. The specific process is the same as step 1 of the embodiment shown in
In step 2′, the anesthesia machine 20 sets a ventilation parameter according to anesthesia machine control information which is inputted by a user. For example, the ventilation parameter is set according to anesthesia machine control information which is inputted by hand and/or anesthesia machine control information which is inputted by voice. The ventilation parameter includes one or more of the above ventilation control parameters, flow meter parameters, electronic evaporator settings, and special function operation. Then the anesthesia machine 20 controls the ventilation of the patient according to the ventilation parameter. The specific process is shown in step 2 of the embodiment shown in
In step 3′, the anesthesia machine 20 sends the corresponding infusion device control instruction to the infusion device 30 according to the ventilation parameter. For example, the anesthesia machine 20 is preset with a corresponding relationship between different ventilation parameters and infusion device control instructions. The anesthesia machine 20 acquires its corresponding infusion device control instruction according to the current ventilation parameter, and then sends the corresponding infusion device control instruction to the infusion device 30. It can be seen that the anesthesia machine 20 can intelligently adjust the parameters of the infusion device 30 according to the ventilation parameter, thus realizing a certain degree of automatic control of the infusion device 30.
In step 4′, the infusion device 30 receives the infusion device control instruction from the anesthesia machine, and controls medication administration to the patient according to the infusion device control instruction. The specific process is the same as step 4 of the embodiment shown in
The above embodiments all refer to that the anesthesia machine 20 controls the infusion device 30. However, in some other embodiments, the anesthesia machine 20 can also be controlled by the infusion device 30, that is, infusion device 30 is the main control device, and the anesthesia machine 20 is the controlled device. As shown in
In step 1″, communication connection is established between the anesthesia machine 20 and the infusion device 30. The specific process is the same as step 1 of the embodiment shown in
In step 2″, the infusion device 30 controls medication administration to a patient according to infusion device control information which is inputted by a user, such as according to the infusion device control information which is inputted by hand and/or the infusion device control information which is inputted by voice. For example, the infusion device 30 generates a corresponding infusion device control instruction according to the infusion device control information which is inputted by hand and/or by voice, by the user, and then controls the medication administration to the patient according to the infusion device control instruction.
In step 3″, the infusion device 30 sends an anesthesia machine control instruction to the anesthesia machine according to anesthesia machine control information which is inputted by a user, such as according to the anesthesia machine control information which is inputted by hand and/or the anesthesia machine control information which is inputted by voice. For example, the infusion device 30 generates a corresponding anesthesia machine control instruction according to the anesthesia machine control information which is inputted by hand and/or by voice by the user, and then sends the corresponding anesthesia machine control instruction to the anesthesia machine 20.
In step 4″, the anesthesia machine receives the anesthesia machine control instruction from the infusion device, and controls ventilation of the patient according to the anesthesia machine control instruction.
The method shown in
In another embodiment, as shown in
The control terminal 10 can be a monitor, computer, tablet computer, etc. The anesthesia control process of the anesthesia control system shown in
In step 1′″, communication connection is established between the control terminal 10 and the anesthesia machine 20 and between the control terminal 10 and the infusion device 30. Similarly, the control terminal 10 is connected with the anesthesia machine 20 via wired communication or wireless communication, which can be connected through the LAN, and the control terminal 10 is connected with the infusion device 30 via wired communication or wireless communication, which can be connected through the LAN. The control terminal 10 also has a communication module. This embodiment also takes the wireless transmission module as an example. The wireless transmission module of the control terminal 10 is responsible for establishing data connection with the controlled device. Specifically, the wireless transmission module of the control terminal 10 is paired with the wireless transmission module of the controlled device, and the data connection is established if the pairing is successful.
At least one of the control terminal 10, the anesthesia machine 20 and the infusion device 30 sends connection indication information after establishing a wireless communication connection with other devices of the anesthesia control system.
In this embodiment, the control terminal 10 indicates that the wireless communication connection has been established with the anesthesia machine 20 after establishing the wireless communication connection with the anesthesia machine 20. For example, the control terminal 10 sends third connection indication information to indicate that a wireless communication connection has been established with the anesthesia machine 20. After establishing the wireless communication connection with the anesthesia machine 20, the control terminal 10 also displays which device is currently connected through its own displayer, that is, the control terminal 10 displays an identification of the anesthesia machine 20 which is connected by wireless communication. The identification of the anesthesia machine 20 can be ID, icon or number of the anesthesia machine 20.
Similarly, the control terminal 10 indicates that the wireless communication connection has been established with the infusion device 30 after establishing the wireless communication connection with the infusion device 30. For example, the control terminal 10 sends fourth connection indication information to indicate that the wireless communication connection has been established with the infusion device 30. After establishing the wireless communication connection with the infusion device 30, the control terminal 10 also displays which device is currently connected through its own displayer, that is, the control terminal 10 displays identification of the infusion device 30 which is connected by wireless communication.
Of course, the anesthesia machine 20 can also indicates that the wireless communication connection has been established with the control terminal 10 after establishing the wireless communication connection with the control terminal 10. For example, the anesthesia machine 20 sends fifth connection indication information, to indicate that the wireless communication connection has been established with the control terminal 10. After establishing the wireless communication connection with the control terminal 10, the anesthesia machine 20 also displays which device is currently connected through its displayer, that is, the anesthesia machine 20 displays identification of the control terminal 10 which is connected by wireless communication.
Of course, the infusion device 30 can also indicates that the wireless communication connection has been established with the control terminal 10 after establishing the wireless communication connection with the control terminal 10. For example, the infusion device 30 sends sixth connection indication information, to indicate that the wireless communication connection has been established with the control terminal 10. After establishing the wireless communication connection with the control terminal 10, the infusion device 30 also displays which device is currently connected through its displayer, that is, the infusion device 30 displays identification of the control terminal 10 which is connected by wireless communication.
The third connection indication information, the fourth connection indication information, the fifth connection indication information and the sixth connection indication information can be sound indication, light indication, vibration indication, or text and graphic indication on an display interface of the displayer.
In step 2′″, the control terminal 10 sends an anesthesia machine control instruction to the anesthesia machine 20 according to anesthesia machine control information which is inputted by the user, and an infusion device control instruction to the infusion device 30 according to infusion device control information which is inputted by the user. For example, the control terminal 10 sends the anesthesia machine control instruction to the anesthesia machine 20 according to the anesthesia machine control information which is inputted by hand and/or the anesthesia machine control information which is inputted by voice, and sends the infusion device control instruction to the infusion device 30 according to the infusion device control information which is inputted by hand and/or the infusion device control information which is inputted by voice. This embodiment takes the control information which is inputted by hand of the user as an example for explanation. Specifically, the display interface of the displayer of the control terminal 10 displays an anesthesia machine setting area for receiving the anesthesia machine control information which is inputted by the user. The anesthesia machine setting area is the same as the above example, so it is not repeatedly described here. The control terminal 10 generates the corresponding anesthesia machine control instruction according to the anesthesia machine control information, and sends the corresponding anesthesia machine control instruction to the anesthesia machine 20 to control the anesthesia machine 20. The control terminal 10 also acquires information of the anesthesia machine 20. The display interface of the displayer of the control terminal 10 also has an anesthesia information display area. The anesthesia information display area is the same as the above example, so it is not repeatedly described here.
The display interface of the displayer of the control terminal 10 also displays an infusion device setting area for receiving the infusion device control information which is inputted by the user. The infusion device setting area is the same as the above example, so it is not repeatedly described here. The control terminal 10 also acquires information of the infusion device 30. The display interface of the displayer of the control terminal 10 also has an injection information display area. The injection information display area is the same as the above example, so it is not repeatedly described here.
Among them, the anesthesia machine setting area and the infusion device setting area can not appear on the same display interface (interactive interface), that is, the two areas can be displayed on different display interfaces of the control terminal 10, or can appear on the same interface of the control terminal 10, that is, the two areas can be displayed on the same display interface at the same time. Users can adjust the parameters of anesthesia machine 20 and infusion device 30 on the same interactive interface, without operating separately on the two devices or walking between the two devices, which improves the work efficiency and safety. Similarly, the anesthesia information display area and the injection information display area can not appear in the same display interface, and can also be displayed in the same interface of the anesthesia machine. In this embodiment, in order to understand completely and control the situation of the patient, the anesthesia machine setting area, the infusion device setting area, the anesthesia information display area and the injection information display area are displayed on the same display interface.
Before the control terminal 10 sends the corresponding anesthesia machine control instruction to the anesthesia machine, it can also determine whether information of the patient in the control terminal 10 is consistent with information of the patient in the anesthesia machine. If yes, the control terminal 10 sends the corresponding anesthesia machine control instruction to the anesthesia machine. Or else, the control terminal 10 disconnects the wireless communication connection, that is, disconnects the wireless communication connection with the anesthesia machine, and also refuses to send the anesthesia machine control instruction, and/or sends an alarm massage, such as outputting third alarm information.
Before the control terminal 10 sends the corresponding infusion device control instruction to the infusion device 30, it can also determine whether information of the patient in the control terminal 10 is consistent with information of the patient in the infusion device 30. If yes, the control terminal 10 sends the corresponding infusion device control instruction to the infusion device 30. Or else, the control terminal 10 disconnects the wireless communication connection, that is, disconnects the wireless communication connection with the infusion device 30, and also refuses to send the infusion device control instruction, and/or sends an alarm massage, such as outputting the fourth alarm information.
The third alarm information and the fourth alarm information can be sound indication, light indication, vibration indication, or text and graphic indication on the display interface of the displayer to warn the user that the information of the patient is currently abnormal.
In step 3′″, the anesthesia machine 20 controls ventilation of the patient according to the anesthesia machine control instruction. The anesthesia machine 20 indicates that the anesthesia machine control instruction has been received after receiving the anesthesia machine control instruction. For example, the anesthesia machine sends third receiving indication information to indicate that the anesthesia machine control instruction has been received.
Before the anesthesia machine 20 controls ventilation of the patient according to the anesthesia machine control instruction, it determines whether information of the patient in the infusion device is consistent with information of the patient in the control terminal. If yes, the anesthesia machine 20 controls the ventilation of the patient according to the anesthesia machine control instruction. Or else, the anesthesia machine disconnects the wireless communication connection, that is, disconnects the wireless communication connection with the control terminal 10, and also refuses to receive or respond to the anesthesia machine control instruction or sends an alarm massage, such as outputting fifth alarm information.
In step 4′″, the infusion device 30 controls medication administration to the patient according to the infusion device control instruction. The infusion device 30 indicates that the infusion device control instruction has been received after receiving the infusion device control instruction. For example, the infusion device 30 sends fourth receiving indication information to indicate that the infusion device control instruction has been received.
The third receiving indication information and the fourth receiving indication information can also be one or more of the following: sound indication (such as indication tone), light indication (such as flashing LED light, color change of all or part of the screen), vibration indication, identification indication of screen display state (such as text, graphics), etc. The controlled device feeds back receiving indication information to the user, which is convenient for the user to confirm that the controlled device has received the control instruction, thus improving the safety of operation.
Before the infusion device 30 controls the medication administration to the patient according to the infusion device control instruction, it can also determine whether information of the patient to whom the infusion device 30 administers medication is consistent with information of the patient in the control terminal 10. If yes, the infusion device 30 controls the medication administration to the patient according to the infusion device control instruction. Or else, the infusion device 30 disconnects the wireless communication connection, that is, disconnects the wireless communication connection with the control terminal 10, and also refuses to receive or respond to the infusion device control instruction or sends an alarm massage, such as outputting sixth alarm information.
The controlled device also provides an option for whether to accept remote control for the user to set. For example, when the user decides that the anesthesia machine 20 can accept remote control, the user can operate the anesthesia machine 20 to send an instruction to start a remote control function (such as selecting the option of accepting remote control). At this time, the anesthesia machine 20 can receive a remote control instruction and execute it, such as allowing to receive the anesthesia machine control instruction or to respond to the anesthesia machine control instruction. When the user does not want this anesthesia machine 20 to be controlled remotely, the user can operate the anesthesia machine 20 to send an instruction to close a remote control function (such as cancelling selection of the option of accepting remote control). The anesthesia machine 20 receives the instruction to close the remote control function, and responds to said instruction by stopping receiving the anesthesia machine control instruction or by stopping responding to the anesthesia machine control instruction. That is, the anesthesia machine 20 is no longer controlled by the control terminal 10, which can avoid subsequent mis-operation.
Similarly, the infusion device 30 receives an instruction to close a remote control function and responds to said instruction by stopping receiving the infusion device control instruction or by stopping responding to the infusion device control instruction. The specific process can refer to the above embodiments, and is not repeatedly described here.
Similarly, in this embodiment, the infusion device 30 can also determine whether the patient is changed, and process the workflow which is restarted after its standby according to the determination result of whether the patient is changed. For example, the infusion device 30 includes a first injection pump. When the first injection pump is in the no-output state or standby state, the working state of the anesthesia machine 20 is acquired. The first injection pump updates the information of the patient of the first injection pump at least based on the acquired working state of the anesthesia machine 20 before starting injection. The specific process is the same as the above embodiments, and is not repeatedly described here.
As another example, the infusion device 30 includes a first injection pump and a second injection pump. When the first injection pump is in the no-output state or standby state, the working state of the second injection pump is acquired. Before the first injection pump starts injection, information of the patient in the first injection pump is updated at least based on the acquired working state of the second injection pump. The specific process is the same as the above embodiments, and is not repeatedly described here.
When the anesthesia machine 20 is in the no-output state or standby state, the working state of the infusion device 30 (that is, the working state of the injection pump) can also be acquired. The anesthesia machine 20 updates the information of the patient of the anesthesia machine at least based on the acquired working state of the infusion device 30 before starting ventilation. The specific process is the same as the above embodiments, and is not repeatedly described here.
In this embodiment, the control terminal 10 is a tablet computer, that is, the above interactive interface is deployed on a mobile tablet computer. The doctor can place the tablet computer at any suitable position in the operating room according to the surgical needs and the space constraints in the operating room, and send a control instruction to the anesthesia machine and injection pump on the tablet computer. The controlled devices, such as the anesthesia machine and injection pump, are interconnected with the main control device, such as the tablet computer, through the wireless transmission module to receive the control instruction, thus realizing the gas delivery and intravenous medication delivery to the patient, and improving the efficiency of the anesthesia operation.
