Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Medical equipment can execute relevant medical work such as guardianship, treatment under medical personnel's control. At present, the medical equipment is provided with entity keys corresponding to various functions, and the medical staff controls the medical equipment in such a way that the medical equipment is instructed to execute the medical procedure of certain function by manually touching the entity keys.

However, this touch mode of operation has a major limitation in some medical scenarios, as will be illustrated by several examples of scenarios.

In aseptic operation scenes such as trachea cannula, vascular puncture and the like, the medical equipment is not aseptic equipment, and the existing manual contact operation mode can possibly generate the problem of cross infection of germs and bring negative influence to the health of patients. Thus, there is currently often a need for multiple medical personnel to cooperate, one of whom is responsible for operating the medical device and the other who performs the sterile medical procedure on the patient. This way of processing is relatively wasteful of human resources. Although some medical equipment is provided with foot treading devices, the aim of operating the equipment by hand asepsis is fulfilled under the condition of reducing the number of matched personnel, the medical equipment has more accessories, is inconvenient to operate and cannot be popularized and applied.

In medical procedures such as cardiopulmonary resuscitation, off-hospital rescue, etc., where the condition is urgent, environmental conditions are often complicated, such as jolt movements, narrow operating spaces, etc., it may be difficult for medical staff to conveniently and manually operate the medical device. Moreover, the number of medical staff in such a scenario is often insufficient, on-site medical staff pay full attention to the condition of the patient, and both hands are busy with treating the patient, so that the equipment operation may not be conveniently performed.

The hospital transport such as sickbed and wheelchair transport, the outside transport such as ambulance, helicopter, airliner and lifeboat transport, and the like, the process is relatively unstable, the operation environment is complex, the keys on the contact operation equipment of medical staff are very inconvenient, and misoperation is easy to occur.

The above medical scenario is merely illustrative, and of course, the medical device of the present invention is not limited to be applied to the above three medical scenarios, and may also include other medical scenarios that restrict the manual manipulation manner as will occur to those skilled in the art.

In order to solve the problem of inconvenience caused by manual operation of medical equipment, the invention provides the medical equipment provided with the audio collector, and a user can realize the operation and control of the medical equipment through a voice instruction. In different application scenarios, the medical device may be a monitor, a telemetry device, a ventilator, an infusion pump, or other devices that implement various medical functions.

See fig. 1, which shows a specific structure of a medical device. As shown in fig. 1, the medical device may include: an audio collector 101, a memory 102 and a processor 103. The configuration of the medical device is not limited to including the two components, and when it is embodied as a device that realizes a specific function, it naturally includes a component unit that realizes the specific function.

The audio collector 101 is configured to collect a voice signal carrying a medical procedure instruction input by a user, and send the voice signal to the processor; the medical procedure instruction is used for instructing the medical equipment to execute a preset medical procedure.

The medical equipment is provided with an audio collector for collecting voice signals, and particularly converting voice analog signals into digital signals which can be recognized by the medical equipment. In practical application, when a user needs a medical device to execute a certain medical function, an instruction can be input to the medical device through voice, and the voice signal carrying the medical procedure instruction is collected by the audio collector and sent to the processor. It should be noted that, one or more programs and data of medical procedures are preset in the medical equipment, and the corresponding medical procedures can be realized by calling the data and executing the programs. The execution of the medical procedure may be considered equivalent to the implementation of the corresponding medical function. For example, when the medical device is specifically an infusion pump, a medical procedure of injecting a drug is provided therein, and the infusion function of the infusion pump can be considered to be realized by executing the medical procedure.

It can be understood that the user inputs the voice signal according to the actual medical requirement, the input time point of the voice signal is not fixed, and in order to realize real-time recording, the audio collector can be started based on the device starting instruction and always kept in the working state so as to continuously detect whether the voice signal is received or not. Of course, if the audio collector is triggered to be turned off by the user based on the consideration of saving electric energy, saving computing resources of the medical device, etc., or the medical device automatically turns off the audio collector if the detection action of the audio collector satisfies the preset off condition. Wherein the preset shutdown condition may include, but is not limited to, no voice signal being detected for a certain period of time, etc.

If the user wants to develop a certain medical operation procedure under the condition that the audio collector is closed, the audio collector can be started by the audio collection starting instruction so as to activate the voice control function of the medical equipment. Specifically, if the processor of the medical device receives an audio collector activation instruction, the audio collector may be activated. The manner in which the processor activates the audio collector may include, but is not limited to, the following.

For example, the medical device may set a physical key for activating the audio control function, which the user may press, and based on the triggering operation, the key generates and sends an audio collector on command to the processor. The processor in turn activates the audio collector to be ready to collect the user-entered speech signal at a time.

For another example, the medical device may include a touch-sensitive display that displays soft keys for activating audio control functions that a user may click to trigger the touch-sensitive display to generate and send an audio collector turn-on command to the processor. After receiving the starting instruction of the audio collector, the processor starts the audio collector to be ready for collecting the voice signals input by the user at any time.

For another example, the medical device may include a touch-sensitive display, and the user may input a preset gesture track, such as drawing a circle or other graphic. After the touch display receives the gesture track, the gesture track is sent to the processor, if the processor judges that the gesture track is a preset gesture track for starting the audio collector, the touch display determines that an audio collector starting instruction is received, and then the audio collector is started so as to be ready for collecting voice signals input by a user at any time.

For another example, the medical device may include a photo-sensor, where the user inputs a light shielding action meeting a preset requirement through the photo-sensor, and specifically, for example, the user blocks the photo-sensor for a time period reaching the preset time period, so that the photo-sensor detects a light change condition meeting the requirement, and further generates an audio collector opening instruction and sends the instruction to the processor. The processor in turn activates the audio collector to be ready to collect the user-entered speech signal at a time.

For another example, the medical device may include an image collector, and the user may display a gesture (such as drawing a triangle, a circle, etc.) that meets a preset requirement, and the image collector may collect an image including the gesture and send the image to the processor. The processor may analyze the image content using image processing techniques, and if a gesture meeting a preset requirement is detected from the image, it may be determined that an audio collector activation instruction is received. The processor in turn activates the audio collector to be ready to collect the user-entered speech signal at a time.

For another example, the medical device may include a biometric collector for collecting biometric information of the user. In practical application, the biological feature collector can be specifically any one of an iris collector, a fingerprint collector, a voiceprint collector and the like. The biological characteristic collector sends the collected biological characteristic information to the processor, and the processor judges whether the user corresponding to the biological characteristic information has opening permission or not. And the processor determines that the starting instruction of the audio collector is received only under the condition that the user corresponding to the biological characteristic information has the starting authority, and then starts the audio collector so as to be ready for collecting the voice signals input by the user at any time. .

Furthermore, the medical device may include an image collector for collecting barcode images, such as one-dimensional codes, two-dimensional codes, etc., input by the user. The barcode image records the identity information of the user, such as name, department, job, etc. After the image collector collects the bar code image, the bar code image is sent to the processor. The processor extracts identity information from the bar code image and judges whether a user corresponding to the identity information has opening authority, and one specific judging mode is that the processor pre-stores the identity information of one or more users with the opening authority and judges whether the received identity information is identical with a certain pre-stored identity information. Only if the user corresponding to the identity information has the opening authority, the user is determined to receive the opening instruction of the audio collector, and then the audio collector is started to collect the voice signals input by the user at any time.

For another example, the medical device may set a communication interface, and the communication interface may receive an audio collector activation instruction sent by another device and send the audio collector activation instruction to the processor. The other devices may be interconnected medical devices within the same medical system or may be separate control node devices. The processor receives an audio collector starting instruction, and then starts the audio collector to be ready for collecting voice signals input by a user at any time.

For another example, the medical device may set a power-on key that the user may trigger to activate the medical device. If the medical equipment receives the equipment starting instruction, the audio collector is started in the starting process so as to be ready for collecting voice signals input by a user at any time.

For another example, when the medical device is required to be used for monitoring the physical sign of a patient for the first time, the user can input a monitoring start instruction to the medical device, and meanwhile, can input related information of the monitored object, such as name, age, sex and the like, to the medical device. After the processor receives the monitoring start instruction, the processor can determine that the start instruction of the audio collector is received, and then the audio collector is started so as to be ready for collecting the voice signals input by the user at any time.

Of course, the above several ways of activating the audio collector are merely illustrative, and other ways that will occur to those skilled in the art are within the scope of the invention. In addition, the closing of the audio collector can also adopt any one of the modes, or a voice signal carrying a closing instruction can also be input, and the processor controls the closing of the audio collector after receiving the closing instruction.

Memory 102 for storing software programs and data.

In particular, the memory may have stored therein a software program for implementing a voice control function and data related thereto. The processor implements the voice control functions described below by calling the software program and related data in memory.

A processor 103 for invoking data stored in the memory by running a software program stored in the memory, performing at least the steps of: after receiving the voice signal, determining a medical action corresponding to the medical procedure instruction, and controlling the execution of the medical action.

After the audio collector sends the voice signal to the processor, the processor analyzes the voice signal, specifically extracts voice content from the digital voice signal, and the voice content is a medical procedure instruction input by a user. The medical procedure instructions are used to instruct the medical device to perform a specific medical procedure, where the medical procedure includes one or more preset medical actions, and the plurality of medical actions may be performed in series, may be performed in parallel, or may be performed in part in series and in part in parallel.

The corresponding relation between the medical procedure instruction and the medical action can be preset in the medical equipment, and the processor can determine the medical action corresponding to the medical procedure instruction according to the corresponding relation after extracting the medical procedure instruction from the voice signal. The medical action may be one or a plurality of medical actions. The processor controls the execution of the medical action, in particular, the medical action may be executed in particular by other components or accessories of the medical device, and the processor controls the other components or accessories to accurately execute the medical action by instructions. For example, the medical device is a monitor and the medical action determined by the processor includes: and displaying a monitoring interface corresponding to a certain monitoring mode, and sending the parameter data of the monitoring interface to a display by the processor so that the display displays the monitoring interface according to the parameter data. As another example, the medical device is an infusion pump and the medical action determined by the processor includes injecting a medication, and the processor controls the pump device of the infusion pump to inject the medication into the subject by instructions. Of course, the medical actions herein are merely examples, and in practical applications, the medical actions controlled by the processor are not limited thereto.

The following details how the processor determines the corresponding medical action based on the medical procedure instructions.

The medical equipment can be provided with an instruction library in advance, wherein the instruction library comprises one or more medical procedure instructions, and different kinds of medical procedure instructions are used for instructing the medical equipment to execute different medical procedures. The same type of medical procedure instruction is only different from a predefined format, but is used to instruct the medical device to execute the same medical procedure. For example, the instruction library includes three medical procedure instructions, "trachea cannula", "trachea cannula for patient", "trachea cannula entering mode", which belong to the same medical procedure instruction, and are all aimed at instructing the medical equipment to execute the medical procedure of trachea cannula.

The medical device may also be configured with an action library that includes one or more medical actions. The medical procedure instructions in the instruction library have a preset corresponding relation with the medical actions in the action library. It is understood that the medical actions corresponding to the same medical procedure instruction are the same. The medical action corresponding to one medical procedure instruction may be one or more, and the correspondence may also indicate that the medical procedure indicated by the medical procedure instruction includes the one or more medical actions.

It should be noted that, one setting manner of the instruction library includes that the medical device is provided with an instruction library configuration function, and the user may input a custom name of the medical procedure instruction into the instruction library, and may set which medical action or actions in the action library the custom medical procedure instruction corresponds to. For example, the user inputs a medical procedure instruction in the instruction library as "blood pressure zeroing" according to daily language habits, and sets the medical action corresponding to the medical procedure instruction as "all IBP channel zeroing", and of course, the medical procedure instruction can also be set to correspond to other medical actions, such as "arterial blood pressure measurement channel zeroing", according to daily use habits.

Another arrangement of the instruction library includes obtaining a function key name of the medical device as a name of the medical procedure instruction. Thus, the user only needs to input voice according to the name of the function key, and the medical equipment can acquire the voice signal containing the medical procedure instruction. After setting the medical procedure instruction according to the function key, further determining the medical action executed by the medical equipment after the function key is triggered, and setting the medical action as the medical action corresponding to the medical procedure instruction. Of course, both of the above approaches may be used in combination.

In addition, the correspondence between the medical procedure instruction and the medical action may be set by a self-learning manner. Specifically, the processor obtains any voice signal carrying any medical procedure instruction through the audio collector in a self-learning mode, and records medical actions executed by the medical equipment within a preset time before and after an input time point of any voice signal; and establishing a corresponding relation between any medical procedure instruction and the recorded medical action.

In particular, the medical device may be set to a self-learning mode, for example, set at the beginning of the medical device's use, or may be manually operated to enter the mode at any other time period. In the self-learning mode, the user can input a voice signal carrying a medical procedure instruction while operating the medical device. After the voice signal is collected by the audio collector, the voice signal is sent to the processor. The processor records the medical procedure instruction in the voice signal, records the medical action executed by the medical equipment before and/or after receiving the medical procedure instruction, establishes the corresponding relation between the medical procedure instruction and the medical action, and obtains a learning result. The self-learning mode may last for a period of time during which the processor may generate a set of correspondence between medical procedure instructions and medical actions through learning and training. The medical procedure instructions are stored in the instruction library, and the medical actions are stored in the action library.

The medical procedure instruction has a predefined format, and if the user inputs a voice signal according to the defined format, the processor can accurately determine the same medical procedure instruction in the instruction library after extracting the medical procedure instruction from the voice signal, and then determine the medical action corresponding to the medical procedure instruction from the action library.

However, the language habits of different users are various, and the medical procedure instructions carried by the voice signals may not completely conform to the predefined instruction format, or the medical procedure instructions in the instruction library are monotonous, and various different expression formats are not set for the same medical procedure instruction. Thus, in practical application, after the processor extracts the medical procedure instruction from the voice signal, the processor needs to search the medical procedure instruction similar to the medical procedure instruction in the preset instruction library. The similarity condition is that the semantics of the medical procedure instructions are analyzed, the semantic similarity of the two medical procedure instructions needs to reach a preset similarity requirement, and the preset similarity requirement can be embodied as a preset similarity threshold. For ease of description, the medical procedure instructions found from the preset instruction library may be referred to as target medical procedure instructions.

In summary, the processor determines a medical action corresponding to the medical procedure instruction, specifically including the steps of: searching a target medical procedure instruction with the semantic similarity reaching a preset requirement from a preset instruction library, wherein the process can be called an instruction matching process; and then determining the medical action corresponding to the target medical procedure instruction in a preset action library. It should be noted that the semantic similarity meets a preset requirement, and includes the case that two medical procedure instructions are identical.

In order to improve the reliability of the instruction matching results, the matching process may interact with the user, who selects the target medical procedure instruction that meets the expectations. Specifically, the processor searches for a medical procedure instruction for which the semantic similarity with the medical procedure instruction reaches a first preset similarity threshold; if so, determining the searched medical procedure instruction as a target medical procedure instruction; if not, searching the medical procedure instruction with the semantic similarity reaching a second preset similarity threshold value, and outputting the searched medical procedure instruction; and receiving a selection instruction of the user for the medical procedure instruction, and determining the medical procedure instruction indicated by the selection instruction as a target medical procedure instruction.

Setting a first preset similarity threshold and a second preset similarity threshold according to actual requirements, wherein the first preset similarity threshold is higher than the second preset similarity threshold. If the medical procedure instruction meeting the first preset similarity threshold is found, the medical procedure instruction can be considered to be the medical procedure instruction expected by the user in the actual demand; if a medical procedure instruction which does not reach the first preset similarity threshold but reaches the second preset similarity threshold is found, the medical procedure instruction can be considered to possibly meet the expectations of the user, and is displayed to the user through the interactive interface and selected by the user. The search result displayed by the interactive interface may only include one medical procedure instruction, so that the user can select the determining operation or can select the cancelling operation; or the search result includes a plurality of medical procedure instructions, and the user may select a certain medical procedure instruction as the target medical procedure instruction.

The above implementation will be specifically described with reference to fig. 2. As shown in fig. 2, a user inputs a voice signal carrying "blood pressure zeroing" to a medical device, after the medical device extracts the medical procedure instruction, semantic search is performed in a preset instruction library, the medical procedure instruction meeting a second preset similarity threshold is found to include "arterial IBP channel zeroing" and "all IBP channels zeroing", and a search result is displayed on an interactive interface for selection by the user. Assuming that the user selects "all IBP channels zero out," the medical procedure instruction is taken as the target medical procedure instruction.

Of course, other steps in the instruction matching process may also interact with the user. For example, after finding a medical procedure instruction that meets the first preset similarity threshold, the medical procedure instruction may be presented to the user through the interactive interface, and the user may be queried as to whether to execute the medical procedure instruction. The user may select the confirm option or the cancel option. After the option is canceled, the user can adjust the format of the medical procedure instruction and re-input the voice signal.

After the target medical procedure instruction is matched in the preset instruction library, searching the corresponding medical action in the preset action library. The medical actions may include a plurality of medical actions having a preset order of execution, and the processor first determines the order of execution of the respective medical actions, and then sequentially controls execution of the respective medical actions according to the order of execution.

The plurality of medical actions may be performed serially. For example, the target medical procedure instruction matched by the processor of the monitor is "5-minute noninvasive blood pressure measurement", the medical actions corresponding to the target medical procedure instruction include two medical actions, namely "NIBP measurement interval time is set to 5 minutes" and "NIBP measurement is started", the execution sequence of the previous medical action is preset to be 1, and the execution sequence of the subsequent medical action is preset to be 2, then the monitor firstly sets the interval time of noninvasive blood pressure (Non-invasive Blood Pressure, abbreviated as NIBP) measurement to 5 minutes, and then automatically starts NIBP measurement every 5 minutes. For another example, the target medical procedure instruction matched by the processor of the monitor is "switch to large font interface", the medical actions corresponding to the target medical procedure instruction include two medical actions, namely "close the current interface" and "display large font interface", and the execution sequence of the previous medical action is preset to be 1, and the execution sequence of the next medical action is preset to be 2, the monitor firstly closes the currently displayed interface, and then generates and displays the large font interface. It should be noted that the execution sequence includes a parallel execution case.

The sequence of the medical actions can be preset in the system of the medical equipment or can be customized by a user through a setting interface. After determining the plurality of medical actions, the plurality of medical actions may be stored in a queue of medical actions to ensure that the plurality of medical actions are performed in sequence.

The execution of the medical procedure may be fed back to the user, for example, by a display interface to the user with visual feedback or by outputting sound to the user with audible feedback, to let the user know that the medical action is being performed. The feedback information output is different for different medical actions. For example, during an NIBP measurement, the monitor displays on the display interface the measurement interval time, the measurement countdown, and the measured real-time pressure value to inform the user that an NIBP measurement is being made. After the monitor finishes the measurement, outputting an ending sound and displaying the final measurement result. For another example, during endotracheal intubation, the monitor may pause displaying all monitored parameters of the respiratory system, such as respiratory rate, end tidal carbon dioxide, respiratory mechanics, etc., and display a prompt message "endotracheal intubation mode has been activated". It should be noted that, the output information of the medical procedure may be set according to actual requirements, and the present invention is not limited specifically.

From the above technical solutions, the present invention provides a medical device having an audio collector and a processor. The user can control the medical equipment to execute the medical procedure comprising a plurality of medical actions through voice, specifically, the user inputs a voice signal carrying medical procedure instructions to the medical equipment, the voice signal is collected by the audio collector and then sent to the processor, and the processor determines the corresponding medical actions for the medical procedure instructions in the voice signal according to the preset corresponding relation between the medical procedure instructions and the medical actions and controls the execution of the medical actions. Therefore, the user can control the medical equipment by using voice without manually performing contact operation, so that the problem caused by a contact operation mode is avoided, and the control mode is more efficient and convenient.

In practical applications, the medical device may be embodied as different types of devices, such as monitors, ventilators, anesthesia machines, infusion pumps, operating lights, operating tables, hospital beds, transfer tables, and tower bridges, among others, wherein tower bridges include hanging towers as well as hanging bridges. The medical device may also include other components based on the audio collector and processor. The different medical devices may have different components, e.g. the monitor may comprise an information output device, e.g. a display, and the monitor may comprise a physiological condition detection accessory, e.g. an oxygen probe, e.g. the infusion pump may comprise a drug infusion component, etc.

The specific content of the medical action is also different in different application scenarios. For example, the medical action may include any one or more of the following types: the trigger information output device outputs a medical action of the medical procedure related content, a medical action of triggering the physiological sign detection accessory to measure, a medical action of triggering the medicine injection part to perform medicine injection, and the like.

An example of an application scenario is when the medical device is a monitor, the medical procedure instructions include at least one of instructions to switch to a target monitoring mode, physiological parameter measurement instructions, display interface operation instructions, and data review instructions.

The medical devices may be interconnected to form a medical device system. If the medical action determined by the processor of the medical device needs to be executed by other medical devices except the medical device, the processor of the medical device determines the execution device corresponding to each medical action, for example, the medical device corresponding to the execution of the medical action can be recorded, and the processor determines the execution device corresponding to the medical action according to the recorded information. And then, the processor of the medical device triggers each execution device to execute the corresponding medical action according to the execution sequence, wherein the triggering mode can be that when the execution sequence of a certain medical action is reached, the processor of the medical device sends the content of the medical action to the execution device corresponding to the medical action so as to trigger the execution device to execute the medical action.

As shown in fig. 3, 3 medical devices are communicatively connected to each other. The medical device a is a medical device that receives the voice signal, and it is assumed that the processor of the medical device determines 3 medical actions, namely, a medical action a, a medical action B and a medical action C, according to the medical flow instruction in the voice signal, and the 3 medical actions need to be executed by the medical device a, the medical device B and the medical device C, respectively. Suppose that the order of execution of 3 medical actions is such that medical action a takes precedence over medical action b and medical action c, and medical action b is concurrent with medical action c. The medical device a first executes the medical action a by itself, and when the execution start conditions of the medical actions B and C are satisfied, the medical device B and the medical device C are simultaneously triggered to execute the medical actions B and C, respectively. Of course, the order of execution of the medical actions may be in other forms, as may the execution device of the medical actions. The execution start conditions of the medical action B and the medical action C may be the same or different, and the time points at which the respective medical actions are executed by the medical device B and the medical device C may be the same or different.

One specific example of an application is where the monitor is communicatively coupled to an anesthesia machine and an infusion pump, respectively. The monitor is provided with an audio acquisition module, and a user can input a medical procedure instruction to the monitor through a voice signal, for example, after BIS (brain double frequency Index) exceeds a certain value, one or more anesthetics are injected into the monitor. The monitor analyzes the medical procedure instruction, and determines that the medical actions corresponding to the medical procedure instruction include two steps: the BIS value is monitored, anesthetic is injected, the fact that the two medical actions need to be sequentially executed is determined, the fact that the former medical action is executed by the monitor is determined, and the fact that the latter medical action needs to be executed by the anesthesia machine and the infusion pump is determined. Therefore, the monitor firstly executes the medical action of monitoring the BIS value, and when the monitored BIS value reaches the numerical value in the voice signal, the monitor respectively sends trigger instructions to the anesthesia machine and the infusion pump so as to respectively instruct the anesthesia machine and the infusion pump to execute the medical action of injecting the corresponding anesthetic.

Another specific example of an application is where the monitor is in communication with a ventilator. The monitor is provided with an audio acquisition module, and a user can input medical procedure instructions to the monitor through voice signals, for example, the medical procedure instructions carried by the voice signals are tracheal intubation. The monitor analyzes the medical procedure instruction, and determines that the medical action corresponding to the medical procedure instruction comprises: pausing the monitoring of the breathing parameter and pausing the ventilation of the ventilator, and determining that the two medical actions can be performed simultaneously, and determining that the former medical action is performed by the monitor itself and the latter medical action is performed by the ventilator. Thus, the monitor performs a medical action of "pause breathing parameter monitoring", while sending a trigger instruction to the ventilator to instruct the ventilator to perform a medical action of "pause ventilator ventilation". The medical action corresponding to the medical procedure instruction of the tracheal cannula further comprises: after the monitor pauses the monitoring of the breathing parameters, the monitor is switched to an endotracheal intubation mode. Therefore, after the monitor performs the medical action of "pause breathing parameter monitoring", the monitor also sets its own mode to the "endotracheal intubation" mode.

In the medical equipment system, the voice signal is collected by one medical equipment in the system and analyzed and processed by the medical equipment. However, the medical devices in the system may all have an audio collector and a processor, and the medical devices may each implement collection and analysis of the voice signals.

The medical device system comprises at least two medical devices, wherein the medical devices comprise a first medical device and a second medical device. The "first" and "second" are only for distinguishing between different medical devices, and do not constitute any limitation on other contents such as the execution sequence of medical actions. The number of the first medical devices and the second medical devices is not limited to one, and may be plural.

The first medical equipment is used for collecting voice signals carrying medical procedure instructions; determining a first medical action corresponding to the medical procedure instruction and performed by the first medical device; executing the first medical action when the execution condition of the first medical action meets the preset condition;

The specific medical procedure instructions corresponding to the monitor, the infusion pump, the anesthesia machine, the breathing machine, the operating lamp, the operating table, the tower bridge, the sickbed and the transferring bed, and the medical actions corresponding to the medical procedure instructions are described above, and are not repeated here.

The present medical device system is described with reference to fig. 4. As shown in fig. 4, the medical device system includes two medical devices, i.e., a medical device a and a medical device B. For the user's voice signal, every medical device in the medical device system can be acquired. That is, each medical device may acquire the same voice signal, but the medical device determines that only the medical action performed by itself is performed according to the medical procedure instruction in the voice signal. For example, the medical device a determines a medical action a according to a medical procedure instruction in the voice signal, and executes the medical action a; the medical device B determines a medical action B based on the medical procedure instruction in the voice signal, and executes the medical action B.

A more specific example of application is in a medical device system comprising: the monitor and the anaesthesia machine which are in communication connection are provided with an audio collector and a processor. The voice signals of the user can be respectively collected by the monitor and the anesthesia machine, for example, the medical procedure instruction carried by the voice signals is that the BIS exceeds a certain value, and certain anesthetic is injected. The monitor analyzes the medical procedure instruction, determines the medical action corresponding to the medical procedure instruction and needing to be executed by the monitor, monitors whether the BIS value reaches a certain value, and sends a trigger instruction to the anesthesia machine when the BIS value reaches the certain value. The anesthesia machine analyzes the medical procedure instruction, determines the medical action corresponding to the medical procedure instruction and needing to be executed by the anesthesia machine, and injects anesthetic indicated by the triggering instruction after receiving the triggering instruction. The monitor and the anesthesia machine execute respective medical actions to complete the anesthesia process in a matching way.

Another specific application example is that the medical device system comprises: the monitor and the respirator both have an audio collector and a processor. The voice signals of the user can be respectively collected by the monitor and the breathing machine, for example, the medical procedure instruction carried by the voice signals is tracheal intubation. The monitor analyzes the medical procedure instruction, determines the medical action corresponding to the medical procedure instruction and needing to be executed by the monitor as a medical action, and pauses the monitoring of the breathing parameters. The anesthesia machine analyzes the medical procedure instruction, determines the medical action corresponding to the medical procedure instruction and needing to be executed by the anesthesia machine as the medical action, and pauses ventilation of the breathing machine. The two medical devices independently perform respective medical actions.

In the case of a communication connection of a plurality of medical devices, the audio collector of the medical device can be activated in different ways.

If a plurality of medical devices have image collectors, one way to activate is to activate the plurality of medical devices using a gesture. Specifically, the first medical device includes: a first audio collector, a first image collector and a first processor; the second medical device includes: the second audio collector, the second image collector and the second processor. The first image collector is used for collecting images and sending the images to the first processor; the first processor is used for detecting gesture actions meeting preset requirements from the image, and if the gesture actions meeting the preset requirements are detected, the first audio collector is started. The second image collector is used for collecting images and sending the images to the second processor; the second processor is used for detecting gesture actions meeting preset requirements from the image, and if the gesture actions meeting the preset requirements are detected, the second audio collector is started. The gesture motion input by the user to the different medical devices may be the same or different. If the acquisition view angle of the image acquisition device of the medical equipment is proper, the gesture action made by the user can be acquired by a plurality of medical equipment at the same time, and then the user can start the plurality of medical equipment at the same time by using the same gesture action.

In another starting mode, after the audio collector of one medical device is started, other medical devices are triggered to start the audio collector. Specifically, the first medical device includes: the first audio collector, the second medical device includes: and the second audio collector. The first medical device is used for generating a starting instruction under the condition that the first audio collector is started, and sending the starting instruction to the second medical device; the second medical device is used for starting the second audio collector after receiving the starting instruction. The starting mode of the first audio collector may be any one of the above. The starting mode is based on the interconnection function between medical devices, and when a certain medical device is started, the starting state is transmitted to other medical devices in communication connection so as to trigger the other medical devices to start the audio collector of the medical device.

In another starting mode, a control device is arranged in the medical device system, one or more medical devices are in communication connection with the control device, and the control device controls the starting of the medical device audio collector. Specifically, the first medical device and the second medical device are respectively in communication connection with the control device, the first medical device comprises a first audio collector, and the second medical device comprises a second audio collector. The control equipment is used for sending a starting instruction to the first medical equipment and the second medical equipment after receiving the starting instruction of the audio collector; the first medical equipment is used for starting the first audio collector after receiving the starting instruction; the second medical device is used for starting the second audio collector after receiving the starting instruction. The starting mode of the audio collector of the control device may be any one of the above. In the starting mode, the independent control equipment manages the medical equipment in the medical equipment system, so that only the parts such as the image acquisition device and the like for receiving the starting trigger instruction are required to be arranged on one control equipment, and all the medical equipment in the system can be free from the parts, thereby simplifying the design of the medical equipment.

Furthermore, the control device may not only start the audio collector of the medical device, but also have a function of analyzing the medical procedure instruction, and after analyzing the medical action, trigger one or more medical devices connected with the control device in a communication manner to execute the medical action. Specifically, as shown in fig. 5, the present application provides a control apparatus including: an audio collector 501, a memory 502, a processor 503 and a communication interface 504.

The audio collector 501 is configured to collect a voice signal carrying a medical procedure instruction input by a user, and send the voice signal to the processor; a memory 502 for storing software programs and data; a processor 503 for calling data stored in the memory by running a software program stored in the memory, at least performing the steps of: determining a medical action corresponding to the medical procedure instruction, and determining medical equipment corresponding to the medical action; obtaining a communication address of the medical equipment and generating a triggering instruction for triggering the medical equipment to execute medical actions; transmitting the communication address and the triggering instruction of the medical equipment to a communication interface; and the communication interface 504 is used for sending the trigger instruction to the medical device according to the communication address of the medical device.

The control device needs to record at least the following information, namely, the corresponding relation between the medical procedure instruction and the medical action; secondly, the corresponding relation between the medical action and the medical equipment indicates that the medical action needs to be executed by the medical equipment; third, the communication address of the medical device. Thus, after the processor of the control device extracts the medical procedure instruction, the processor can determine the medical action corresponding to the medical procedure instruction according to the first record information, determine which medical device needs to execute the medical action according to the second record information, determine the communication address of the medical device according to the third record information, and then send a trigger instruction to the communication address through the communication interface so as to trigger the medical device to execute the medical action. The triggering instruction can carry relevant information of the medical action, so that the medical equipment can execute the medical action according to the relevant information after receiving the triggering instruction.

In practical application, when a complex medical procedure is executed for a patient, the monitor needs to be set in all directions, such as interface data, workflow and the like, and the method can be realized by setting a monitoring mode. The invention also provides a monitor, and a user can instruct the monitor to realize the switching of the monitoring modes through voice signals.

Referring to fig. 6, the monitor specifically includes a sensor attachment 601, an audio collector 602, a memory 603, a processor 604, and a display 605.

Wherein the configuration information may include monitoring interface configuration information; the processor sets the specific implementation mode of the monitor according to the configuration information, and controls the display to display the target monitoring interface corresponding to the monitoring interface configuration information based on the monitoring interface configuration information.

Specifically, the monitoring interface configuration information is used to represent the style and content information of the generated monitoring interface. The processor may generate a monitoring interface with a style and content based on the monitoring interface configuration information, which may be referred to as a target monitoring interface.

Therefore, on one hand, the monitor can collect physiological sign parameter data of a monitored object, process the physiological sign parameter data, such as generating a monitoring interface comprising a real-time value, a waveform chart, a trend chart and the like of the physiological sign parameter, and display a processing result to a user; on the other hand, the method can also collect the voice signal of the user, obtain the configuration information corresponding to the monitoring mode according to the indication of switching to a certain monitoring mode in the voice signal, wherein the configuration information can comprise the configuration of a display, the configuration of a processor, the configuration of various detection accessories and the like, and further carry out omnibearing setting on the monitor according to the configuration information.

In addition to setting the monitor to a certain desired monitoring mode via voice commands, the monitor may be instructed to perform certain desired medical actions via voice commands in the monitoring mode.

Therefore, on the basis of the functions, the audio collector is also used for collecting the voice signal carrying the medical operation instruction related to the target monitoring mode and sending the voice signal to the processor; the processor is further used for extracting medical operation instructions related to the target monitoring mode from the voice signals, determining medical actions corresponding to the medical operation instructions related to the target monitoring mode and controlling execution of the medical actions. Note that, the description of the medical operation instruction may be referred to the above medical procedure instruction. The medical actions that the user expects the monitor to achieve are all medical actions in the target monitoring mode.

Application scenario example 1: patient transfer scenarios include, in particular, various types of transfer scenarios such as intra-hospital transfer, extra-hospital transfer, and the like.

During the transportation process, the medical staff and the patient are usually in a moving state, and the external environment is relatively unstable. At this time, the medical staff is very inconvenient to manually operate the medical equipment, and misoperation is easy. Therefore, when a patient is ready to be transported, the audio collector of the medical equipment can be started, and the voice instruction function is activated, so that the medical equipment can be controlled by voice to realize functions in the transportation process, and the operation accuracy and efficiency are greatly improved.

First, the monitor is instructed to enter an indoor transit mode or an outdoor transit mode by voice. For example, the user enters a voice signal "indoor transit mode", and the monitor sets itself to the indoor transit mode in response to the voice signal. Specific setup content includes, but is not limited to: the switching interface is displayed as a large font interface, and the simplified interface elements shield unnecessary information such as hiding alarm limit values, increasing alarm volume and automatically switching monitoring parameters. The reason for automatically switching the monitoring parameters is that the parameters monitored during transportation may be different from those during non-transportation, for example, invasive blood pressure monitoring and airway monitoring respiration rate in hospitalization ward, and noninvasive blood pressure monitoring and impedance monitoring respiration rate during transportation are changed. Note that the transfer mode may be specifically referred to as an indoor transfer mode, and corresponds to an indoor transfer scene. The user can also control the monitor to enter an outdoor transport mode by voice. For example, if an outdoor glare environment is encountered during a transit, the user enters a voice signal "outdoor transit mode" in response to which the monitor sets itself to outdoor transit mode. Specific setup content includes, but is not limited to: the outdoor display mode is adopted, the outdoor display mode is high-contrast display, white or orange-yellow high-contrast is generally adopted, and the problem of difficulty in viewing a display screen due to too strong outdoor sunlight is avoided.

In the transit mode, the voice instructs the monitor to perform noninvasive blood pressure measurements. Specifically, when the patient blood pressure needs to be known, the medical staff controls the monitor to start single NIBP measurement through voice 'NIBP measurement', and if the non-invasive blood pressure measurement needs to be timed, the medical staff controls the monitor to start the NIBP measurement every 5 minutes through voice '5-minute NIBP measurement'.

In the transfer mode, the voice instructs the monitor to perform invasive blood pressure zeroing. In particular, jolts during transit may lead to inaccurate monitoring of invasive blood pressure (Invasive Blood Pressure, IBP for short), thus requiring re-zeroing of the invasive blood pressure monitoring. The zero calibration of the invasive blood pressure channel can be performed on only one channel, can be performed on multiple channels simultaneously, and can be performed on all channels simultaneously. Specifically, for a specific IBP channel, such as an Arterial (abbreviated Art) channel or a central venous pressure (Central Venous Pressure, abbreviated as CVP) channel, after zero calibration preparation is performed, a voice command "Art zero calibration" or "CVP zero calibration" starts zero calibration, and measurement is resumed after zero calibration is completed. For a plurality of IBP channels such as Art, CVP, etc., after the zeroing preparation is made together, the voice command of 'Art, CVP two-channel zeroing' or 'all IBP zeroing' starts zeroing, and the measurement is recovered after the zeroing is completed. The whole process can be carried out by hands of medical staff into treatment of the patient end without manually operating the monitor, and meanwhile, the hands of the medical staff wearing the sterile gloves can be prevented from being polluted by the contact of the monitor.

In the transit mode, the voice instructs the monitor to enter the endotracheal intubation mode. In particular, before a patient is required to be intubated, the hands of the healthcare worker are often provided with sterile gloves, which are not suitable for touching the device, so that the patient may be instructed to enter the endotracheal intubation mode by voice "enter intubate mode". In this mode, the monitor may mask parameter monitoring alarms associated with the respiratory system, such as respiratory rate, end-tidal carbon dioxide, respiratory mechanics monitoring.

In the transit mode, the voice instructs the monitor to enter the rescue mode. Specifically, if the patient is in critical condition and needs to be rescued, the hands and the attention of the medical staff are mainly concentrated on the patient side, and the monitor cannot be manually operated in time to be switched to the rescue mode, so that the monitor can be indicated to be switched to the rescue mode by voice 'entering the rescue mode'.

In the transfer mode, the voice instructs the monitor to conduct 12-lead electrocardiographic analysis. Specifically, chest pain patients need to be subjected to electrocardiographic analysis in time to judge whether cardiac intervention operation is needed. Therefore, the medical staff connects 12 electrocardiograph electrodes for electrocardiograph analysis to the patient manually, at this time, the main operation of the medical staff is concentrated on the patient, and then the patient can be instructed to enter a 12 guide analysis special interface through voice 12 guide analysis to start 12 guide analysis and obtain analysis results, then the analysis results can be sent to emergency center equipment through a communication network through voice 12 guide report, and an emergency center expert judges whether the patient needs to do heart bypass operation or not, if so, the patient can be scheduled to go to a nearby hospital capable of executing bypass operation.

In the transfer mode, relevant information of the operation event is recorded through voice. In particular, emergency situations such as sudden cardiac arrest may occur during patient transport, where a medical professional may not be able to schedule a record of the emergency procedure exclusively due to the limited number of emergency personnel. Therefore, medical staff can dictate the operation steps while carrying out first aid on patients, the monitor converts the voice into characters to form operation events, and the operation events are added into a time mark to form a first aid event record list.

In the transfer mode, the infusion pump is voice activated or deactivated. In particular, administration using an infusion pump during delivery may require the end of administration or suspension of a medication. At this time, the infusion pump is positioned relatively low relative to the medical staff, and thus, the medical staff can use voice to control the operation of the infusion pump, such as stopping or starting one or more infusion pumps, stopping the injection of a certain medicine, and injecting a certain medicine at a certain speed, for example, "stop the injection of dopamine", "start the injection of dopamine xx ml/min".

In the transfer mode, the voice-controlled monitor is in communication with other devices. In particular, patients who are able to move within a certain range may wear wearable mobile devices for monitoring, such as telemetry devices, transfer monitors, wearable measurement modules, etc. When they leave the sickbed, the medical staff controls the appointed mobile device to pair with the appointed bedside monitor through the voice input, so that the medical staff can see the vital sign monitoring condition of the nearby movable patient from the large screen of the bedside monitor of the patient in the ward. The technology can also be suitable for the patient transported from the position A to the position B, and the medical staff can carry out wireless pairing with the existing monitor at the position B by controlling the mobile device transported to the position B along with the patient through voice.

See fig. 7, which shows one example of pairing a mobile device with a monitor. The mobile device is a monitoring device which is transported to a place along with a patient, and can acquire a voice signal of the pairing device 1 sent by a user under the condition that a voice acquisition device of the mobile device is started. Further, the mobile device issues a device search message to obtain a list of searched devices. The mobile device determines the device 1 in the device list, and establishes interconnection with the device 1 according to the address of the device 1 and the communication request. The device 1 agrees to establish the interconnection so that the device 1 and the mobile device complete the interconnection. The voice signal "device 1" used for distinguishing the devices can be the identification of the device name, the sickbed number associated with the device, the device number and the like which can be used for determining the identity of the device.

It should be noted that the above voice control technique is not only suitable for a monitor, but also can be extended to various medical devices possibly used in the transportation process, such as a monitor treatment device including a defibrillation monitor, a breathing machine, an infusion pump, an oxygen supply device, and an external membrane pulmonary oxygenation (Extracorporeal Membrane Oxygenation, abbreviated as ECMO).

Application scenario example 2: peri-operative scenario, the peri-operative phase includes three phases of induction phase, maintenance phase and recovery phase.

In the perioperative period, an operating doctor is mainly responsible for carrying out operation on patients, and an anesthesiologist is responsible for managing medical equipment such as monitors, anesthesia machines, respirators, infusion pumps and the like. In order to create a proper operation station position for an operation doctor by matching different operation types, the anesthesiologist always spends a certain time combining factors such as an anesthesia mode, a patient position, an operation station position, an operation using device position and the like, and adjusts the positions of peripheral medical devices of an operation table. Once these medical device locations are determined, they typically do not move any further during the procedure, which can cause the anesthesiologist inconvenience of operating the medical device. Therefore, the anesthesiologist can use voice to control the medical equipment, so that the equipment operation convenience can be improved, and the anesthesiologist can be more flexibly positioned during the operation.

In the induction period, the anesthesiologist generally takes medicine through a mask, at the moment, the anesthesiologist mainly stands on the head of the patient, then infuses other medicines through an infusion pump or a bolus injection, and then monitors the monitoring parameters of the monitor to judge the anesthesia state and the anesthesia depth of the patient, and confirms that the medicine dosage is proper. At this stage, the anesthesiologist performs anesthesia on the patient with the primary station at the patient's side, possibly at a distance from these medical devices, and the operation is inconvenient, so that the following functions can be achieved using voice-controlled medical devices:

Firstly, a voice signal 'enter induction period monitoring' is input into a monitor, and the monitor is controlled to enter an operation induction period monitoring mode. In this mode the monitor provides, but is not limited to, a monitoring interface suitable for use during the induction period, the interface including commonly used induction period monitoring parameter values and trend graphs. And if the monitor judges that the patient does not perform invasive blood pressure monitoring, starting noninvasive blood pressure monitoring.

Then, the anesthesia machine is controlled to inhale an appropriate amount of anesthetic gas to the patient through the voice signal. For example, the voice signal is "4% concentration of sevoflurane by anesthesia machine", and the anesthesia machine is controlled to deliver sevoflurane gas to the patient at a concentration of 4%.

The one or more infusion pumps are then controlled by the voice signal to push intravenous anesthetic into the patient. For example, the voice signal is "pump propofol 2.0mg/kg by 60kg", and the infusion pump with propofol is controlled to bolus 120mg of propofol to the patient as indicated by the voice signal.

And then, after judging that the patient enters an anesthetic state, opening the artery of the patient and placing a tube into the blood vessel for IBP monitoring. At this time, the monitor may be controlled to perform IBP zeroing using the voice signal "IBP zeroing".

Then, a voice signal of 'monitor muscle relaxation TOF mode start' is input to the monitor, so that the monitor selects a muscle relaxation working mode to be 'TOF mode', and muscle relaxation monitoring is started. And, the infusion pump can be controlled to push muscle relaxant to the patient to monitor related medicines, for example, an anesthesiologist sends a voice signal of '4 mg of the pump muscle relaxant power moon xi', so as to control the infusion pump provided with the power moon xi to push muscle relaxant to the patient. The TOF (Train-Of-Four) mode is a specific muscle relaxation stimulation mode, and the voice indication-activated muscle relaxation stimulation mode can also comprise other modes, such as a muscle relaxation single stimulation mode, a muscle relaxation forced stimulation mode, a muscle relaxation post-forced stimulation mode, a muscle relaxation double short and strong direct stimulation mode and the like.

In the maintenance period, the anesthesiologist needs to maintain the vital sign of the patient stable and ensure that the patient meets the operation requirement, so that the patient vital sign change needs to be continuously focused, and timely administration is performed when certain situations occur, such as operation of an infusion pump for administration, operation of an anesthesia machine for inhalation of anesthetic gas, oxygen and the like. At this time, the anesthesiologist generally stands or sits beside the anesthesia machine, and may be far away from the monitor, infusion pump, etc., and operate inconveniently, so that the following functions may be achieved using the voice input control device.

When the patient reaches the operative state, the anesthesiologist can stop the administration of the drug by voice control of the anesthesia machine. When the anesthesia state of the patient becomes gradually shallower, the drug administration work of the anesthesia machine can be started through voice control. When it is desired to administer an injection, the anesthesiologist also administers the drug by voice control of the infusion pump, for example by voice control of a certain infusion pump to deliver a drug amount of 0.2ug.

During the resuscitation phase, the patient is transported to the resuscitation room, and the ambulatory device such as the transfer monitor also comes with the patient to the resuscitation room. At this time, medical staff can control the mobile device through the pronunciation, shift patient data to the assigned monitor in the resuscitation room, ensure that patient's whole perioperative data is complete. Wherein the voice signal may include, but is not limited to, "patient transfer," patient data including, but not limited to, patient information, vital sign parameter monitoring values, waveform diagrams of vital sign parameters, alarm information, resuscitation scoring results, and the like.

Application scenario example 3: bedside monitoring mode for inpatients, especially in the context of hemodynamic monitoring around the circulatory system. The bedside monitoring mode may specifically include: intensive care mode, sub-intensive care mode, general ward care mode.

During patient vital sign monitoring and treatment, medical personnel perform a series of care and treatment procedures primarily around the patient. When medical staff is busy or the hands are not enough, the medical equipment cannot be conveniently operated manually, and then the medical equipment can be controlled through voice signals, so that the hands of the medical staff are liberated, the convenience of using the medical equipment is improved, and the time for using learning equipment is reduced. Clinically, the functions of a device suitable for using voice control include the following aspects.

The voice control of electrocardiograph functions includes, but is not limited to: the voice control displays the electrocardio waveforms, such as II electrocardio waveforms, I electrocardio waveforms, V electrocardio waveforms and the like; a voice adjusting filtering mode, such as an ST analysis switch is turned on when ST segments in an electrocardiogram are analyzed, the filtering mode is set to be an ST mode, and an operation mode is used during operation; for a paced patient, the voice mark pacemaker is in an on state; for those requiring arrhythmia analysis, the speech turns on the switches of arrhythmia analysis.

Voice control of non-invasive blood pressure measurements, including in particular but not limited to: adjusting the initial inflation pressure value by voice; selecting one of a plurality of measurement modes such as a manual mode, an interval mode, a continuous mode, a sequence mode and the like by voice, and setting interval duration by voice in the interval mode; voice-initiated NIBP measurement; during the interval measurement interval, a manual measurement may be initiated using voice control; opening an NIBP measurement list by voice to intensively display measurement results in a period of time; the alarm limit value of the noninvasive blood pressure is set according to the voice of the patient, for example, the voice signal is an NIBP alarm limit, the alarm limit setting of the corresponding parameters is opened, and the alarm limit value is set through the voice signal. Of course, the setting of the alarm limit is not limited to the blood pressure, but the alarm limit of other physiological parameters can be set by voice.

Voice control of invasive pressure zeroing, including in particular but not limited to: for a specific IBP measurement such as Art, after zero calibration preparation is made, the Art is started by voice for zero calibration; after zeroing preparation is made for multiple IBP measurements, such as Art and CVP, together, the voice-activated multi-channel zeroing is performed.

Voice control of cardiac displacement measurements, including in particular but not limited to: the voice is input into the height and weight of the patient to enable the device to calculate the body surface area for use in heart displacement or continuous heart displacement measurements. For example, the voice signal is input to the medical device as "height 175 cm, weight 58 kg", the medical device displays the body surface area calculation result "1.706 square meters" on the interface, and the voice prompt "1.706 square meters". Alternatively, the medical device may also calculate a Body Mass Index (BMI) of the patient and give an interface and audible prompts.

Hemodynamic physiological map playback process voice control, including in particular but not limited to: the playing speed of the hemodynamic physiological map is controlled by voice, such as slow playing, so that a doctor can clearly see the parameter measurement values of all parts, and a voice signal is played at a speed of 0.5 times or at a speed of one time; the speech freezes the hemodynamic physiological map, and the speech signal, for example, the "frozen physiological map".

The voice control of the passive leg lift test or the capacity load test specifically includes, but is not limited to: opening a passive leg lifting test observation window by voice; starting a voice control marking test, starting a function and marking a baseline; and finishing the test observation by voice control. The process of operating the patient by the medical staff to perform the leg lifting test comprises the steps of firstly enabling the upper body of the patient to be slightly raised, then rapidly laying the upper body of the patient and lifting the legs of the patient, enabling blood in the patient to rapidly flow back to the heart of the patient, then recovering the normal bedridden state of the patient for a period of time, and observing the change condition of hemodynamic parameters.

Voice control of sepsis screening and treatment procedures. The specific control process can be as follows: firstly, a voice instruction of SOFA score is used for opening a sepsis related organ failure assessment (Sepsis Related Organ Failure Assessment, SOFA for short) function on a monitor for sepsis screening; then the operator holds the biochemical examination result of the patient, sequentially recites the test result on the laboratory sheet according to the SOFA scoring items, and the monitor receives the language information and then scores according to the scoring requirement, and gives treatment suggestions according to the screening rules. For example, the speech signal contains on-board test results of "oxygen partial pressure 410, platelets 147, bilirubin 2.1, mean arterial pressure 72, glasgow coma score 13, creatinine 1.3, urine volume 470"; after the monitor receives the language information, scoring is carried out according to scoring requirements, for example, the oxygen partial pressure is 410 to be 0, the platelet 147 is 1 to be 2, the bilirubin is 2.1 to be 2, the mean arterial pressure is 72 to be 0, the glasgow coma score is 13 to be 1, the creatinine is 1.3 to be 1, the urine volume is 470 to be 3, and then the total score is 8 obtained by accumulating all the scores; the monitor then derives from the screening rules that the patient meets sepsis criteria and recommends sepsis therapy.

If sepsis treatment is desired in the patient, the treatment may also be recorded by voice. The monitor adds the treatment measures to the occurrence time, and then generates a treatment event which is stored in the patient data. For example, the user inputs a voice signal "monitor patient blood glucose condition" to the monitor, and the monitor plus system time "2019-1-3" gets a treatment event "2019-1-3 to monitor patient blood glucose condition". Note that the scoring function of the voice control is not limited thereto, and may be a glasgow coma score, a resuscitation score, a pain score, or the like.

It should be noted that the above several application scenarios are merely examples, and the application of the medical device is not limited thereto. Through the realization of the voice control medical equipment function, the manual operation steps of a user can be simplified, and the convenience of operation equipment is improved.

A specific example of the medical device is a monitor, and a specific structure of the monitor is shown in fig. 8. Fig. 8 provides a system frame diagram of a parameter processing module in the multi-parameter monitor.

The parameter processing module is used for external communication and power interface for communicating with the host and taking electricity from the host. The parameter processing module also supports an externally inserted parameter module, which can be used as an external accessory of the monitor by being inserted into the parameter module to form a plug-in monitor host as a part of the monitor or by being connected with the host through a cable. In addition, the multi-parameter monitor includes a memory 817 for storing computer programs and various data generated during the relevant monitoring process.

The internal circuitry of the parameter processing module is disposed within the housing, as shown in fig. 8, and includes at least two signal acquisition circuits 812 corresponding to physiological parameters, a front-end signal processing circuit 813, and a main processor 815.

The audio collector 821 is connected to the processor 815. The audio collector 821 may be embodied as a microphone or the like for collecting a voice signal.

The reason that front-end signal processor was supplied with power by the isolation power is the DC/DC power that keeps apart through the transformer, has played the effect of isolating patient and power supply unit, and main objective is: 1. isolating the patient, and floating the application part through an isolating transformer to ensure that the leakage current of the patient is small enough; 2. the voltage or energy during defibrillation or electrotome application is prevented from affecting the board card and devices (ensured by creepage distance and electric gap) of intermediate circuits such as a main control board.

The main processor completes the calculation of the physiological parameters, and sends the calculation result and waveform of the parameters to the host (such as a host with a display, a PC, a central station, etc.) through an external communication and power interface, and the external communication and power interface 816 may be one or a combination of local area network interfaces formed by Ethernet (Token Ring), token Bus (Token Bus), and a backbone network fiber optic distribution data interface (FDDI) serving as the three networks, or one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, etc., or one or a combination of wired data connection interfaces such as RS232, USB, etc.

The external communication and power interface 816 may also be one or a combination of both a wireless data transfer interface and a wired data transfer interface. The host computer can be any one of a host computer of a monitor, an electrocardiograph, an ultrasonic diagnostic apparatus, a computer and the like, and can form a monitoring device by installing matched software. The host can also be communication equipment, such as a mobile phone, and the parameter processing module sends data to the mobile phone supporting Bluetooth communication through the Bluetooth interface so as to realize remote transmission of the data.
