Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Medical equipment can monitor the physiological parameters of patients, and the monitoring results can be displayed in the form of graphs such as trend graphs and waveform graphs. In the process of continuous monitoring of medical equipment, the graphics may change as the patient's physiological status changes. If medical staff find abnormal changes in the graphics, they can operate the medical equipment to freeze the abnormal graphics fragments. The frozen graphic fragments can provide data support for subsequent analysis of abnormal signs.

The current medical equipment is equipped with a physical freeze button. If the medical staff finds abnormal fluctuations in the monitoring graph and it is right next to the medical device, they manually press the freeze button. If the medical staff is far away from the medical device, they need to come to the side of the medical device and trigger the freeze button. In response to the freezing instruction, the medical device can freeze a graphic segment from the monitoring graphic. However, this freezing method requires medical staff to manually operate medical equipment. For medical staff, the operation method is not convenient enough and the user experience is not good.

The present invention provides a medical device, which may specifically include a monitor, a central station, and the like. As shown in FIG. 1, the medical equipment may specifically include: a display 101, an audio collection device 102, a memory 103, and a processor 104. Among them, the processor 104 is connected to the display 101, the audio collection device 102 and the memory 103 respectively.

The display 101 is used for displaying graphic data of at least one physical parameter of the monitored object.

Among them, the medical device can monitor one or more physical parameters of the monitored object and generate graphical data of the physical parameters. Graphic data can include waveform graphs, trend graphs, or other types. The monitor can display the graphic data obtained by monitoring for the user to view.

It should be noted that the physical sign parameters monitored by the medical device may be one or more. The specific number is determined by the monitoring requirements in actual applications.

The audio collecting device 102 is used to collect the voice signal input by the user and carrying the freezing instruction, and send the voice signal to the processor.

In practical applications, when a user needs to freeze a certain piece of graphic data, he can input a freezing instruction to the medical device in the form of voice. The medical equipment is provided with an audio collection device, and the audio collection device can collect the voice signal carrying the freezing instruction.

It should be noted that the timing point for the user to input the voice signal may not be fixed. In order to achieve real-time recording, the audio collection device can be automatically kept in the working state to continuously detect whether the voice signal is received. Of course, based on considerations such as saving power and saving medical equipment computing resources, the user can trigger the shutdown of the audio collection device, or the medical device can automatically shut down the audio collection device when the detection action of the audio collection device meets the preset shutdown conditions . The preset closing condition may include, but is not limited to, that no voice signal is detected for a certain period of time.

In the case that the audio collection device is turned off, if the processor of the medical device receives a freeze start instruction, the audio collection device can be restarted. The way for the processor to start the audio collection device may include but is not limited to the following ways.

For example, a frozen physical button can be set on the medical device, and the user can press the button, and based on the trigger operation, the button generates a freezing start instruction and sends it to the processor. The processor then turns on the audio collection device to be ready to collect the voice signal input by the user at all times.

For another example, the medical device can display a frozen soft key through the display, and the user can perform a click trigger operation on the soft key to trigger the display freeze start instruction, and the display sends the freeze start instruction to the processor. The processor then turns on the audio collection device to be ready to collect the voice signal input by the user at all times.

For another example, a photoelectric sensor device can be installed on the medical equipment. The user inputs a light blocking action that meets the preset requirements through the photoelectric sensor device. Specifically, for example, the user blocks the photoelectric sensor device for a preset period of time so that the photoelectric sensor device can detect The required light changes, and then generate a freeze start command and send it to the processor. The processor then turns on the audio collection device to be ready to collect the voice signal input by the user.

For another example, an image acquisition device can be set on the medical equipment, and the user can show gesture actions (such as drawing a triangle, circle, etc.) that meet the preset requirements. The image acquisition device can collect an image containing the gesture action and send the image to processor. The processor can use image processing technology to analyze the content of the image, and if a gesture action that meets the preset requirements is detected from the image, it can determine that a freeze start instruction is received. The processor then turns on the audio collection device to be ready to collect the voice signal input by the user at all times.

For another example, a power-on button is provided on the medical device, and the user can trigger the button to start the medical device. If the medical equipment receives the equipment start instruction, it turns on the audio collection device during the startup process to prepare to collect the voice signal input by the user.

For another example, when it is necessary to use medical equipment to monitor the physical signs of a patient for the first time, the user can input the monitoring start instruction to the medical equipment, and at the same time input the relevant information of the monitored object to the medical equipment, such as name, age, gender, etc. . After the processor receives the monitoring start instruction, it can determine that it has received the freeze start instruction, and then turn on the audio collection device to be ready to collect the voice signal input by the user at any time.

Of course, the above several ways of turning on the audio collection device are only examples, and other ways that can be thought of by those skilled in the art are all within the protection scope of the present invention.

The memory 103 is used to store software programs and data.

Specifically, the memory may store a software program and related data for realizing the freezing of the graphics segment. The processor realizes the following function of freezing the graphics segment by calling the software program and related data in the memory. The freezing of a graphic segment can also be called a snapshot or capture of the graphic segment.

The processor 104 is configured to call the data stored in the memory by running a software program stored in the memory, and perform at least the following steps: determining freezing information based on the freezing instruction in the voice signal, the freezing information including at least: frozen target sign parameters And the freezing time period; in the graphic data of the target physical sign parameter, the graphic fragment corresponding to the freezing time period is obtained; the graphic fragment is frozen.

Specifically, after the processor receives the voice signal, it can analyze the voice signal and extract the freeze instruction from it. Based on the trigger of the freeze instruction, the step of freezing the picture is executed. First, the processor determines the relevant information of the graphic segment to be frozen according to the freezing instruction. The relevant information includes at least two items: the sign parameter (ie, the target sign parameter) corresponding to the graphic segment to be frozen and the freezing time period. The following respectively explain how the two information items are determined.

First, how to determine the target physical parameters based on the freezing command in the voice signal.

One way of implementation is that the processor determines whether the freezing instruction includes a sign parameter identifier; if the freezing instruction includes a sign parameter identifier, the sign parameter indicated by the sign parameter identifier is determined as the target sign parameter; if the freezing instruction does not include a sign parameter Parameter identification, then all the displayed physical parameters are regarded as target physical parameters.

Specifically, there may be multiple physical sign parameters monitored by the medical device. If the user finds abnormal fluctuations in one or some of the physical parameters, he can use the voice signal to input the freezing instruction, and indicate the sign of the physical parameter that needs to be frozen in the freezing instruction . For example, the freezing instruction input by the user through the voice signal is "freeze blood oxygen", which means that the user instructs to freeze the blood oxygen waveform. After receiving the freezing instruction, the processor uses the sign parameter indicated by the sign parameter identifier included in the freezing instruction as the target sign parameter.

It should be noted that the identification of some physical signs may be associated with multiple graphics data. If the freezing instruction entered by the user contains this type of physical signs, it can be set by default. In this case, the user indicates to associate all The graphic data is frozen. For example, the freeze command in the voice signal is "Freeze ECG", which means that the user wants to freeze the waveforms of all channels related to the ECG. Of course, other default settings can also be made based on the user's usage habits. For example, users are accustomed to using "ECG" to indicate a certain channel or some specific channels of the ECG, so that the physical parameter identification "ECG" can be mapped to this or these specific channels in advance, so as long as the user's voice signal contains The freeze command of "Freeze ECG" can determine which channel or channels of ECG the user instructs to freeze.

In addition, the freezing instruction can include a physical parameter identifier. For example, the freezing instruction in the voice signal is "freeze ECG II lead", which means that the user wants to freeze only one waveform of the ECG II lead. The freezing command can also include multiple sign parameter identifiers at the same time. For example, the freezing command in the voice signal is "freeze ECG II lead, Art, CO2", which means that the user wants to freeze three waveforms at the same time: ECG II lead waveform, arterial pressure Art Waveform and end-tidal carbon dioxide waveform. It should be noted that if the freezing instruction of the voice signal includes multiple physical parameter identifiers at the same time, it can be explained that the freezing time periods of the graphic data of the physical parameter identifiers are the same.

It should be noted that, in the implementation manner provided above, the freezing instruction is included in one voice signal. Of course, the freezing instruction can also be implemented by multiple voice signals. For example, the user inputs the first voice signal, and the freezing instruction in the voice signal is used to start the menu, and then guides the user to input the second voice signal based on the menu. The freezing instruction of the voice signal contains the physical parameter identification selected by the user from the menu.

Specifically, the user may input a voice signal containing a freezing instruction to the medical device, and after receiving the voice signal, the processor displays a menu containing one or more physical parameter identifiers. The sign of the physical sign parameter in the menu may be the sign of each physical parameter currently displayed on the display. The user selects a physical sign parameter identifier according to the freezing requirement, and includes the selected physical parameter identifier in the voice signal and inputs it to the medical device. Wherein, the sign parameter identification can be the label of the sign parameter in the menu, or it can be the name of the sign parameter. After the processor receives the voice signal, it determines the physical sign parameter indicated by the voice signal as the target physical sign parameter.

However, if the processor does not parse the sign parameter identifier from the freezing instruction, the processor may use all the sign parameters displayed on the display as the target sign parameters. For example, if the voice signal input by the user is "frozen", the processor will determine all the physical parameters displayed on the display, such as all channels of the ECG, blood oxygen, invasive arterial pressure, central venous pressure, end-tidal carbon dioxide, etc., as the target signs parameter.

It should be noted that the display area of the display is limited, and there may be two special situations in practical applications: one is that the display interface displays other data of the physical parameters, but the graphical data of the physical parameters is not displayed, for example, the display interface only displays the physical signs The monitored value of the parameter, but the waveform diagram of the physical parameter is not displayed due to insufficient display space. Second, when the medical equipment monitors multiple physical parameters, the display interface may currently only display the graphical data of a part of the physical parameters, and the graphical data of other physical parameters are in the state to be displayed. The user can switch operations such as on the display Enter a sliding gesture to switch to display the graphic data of other physical parameters.

If there is a situation where all the graphics data is not displayed due to the limitation of the display area, the processor can only use the sign parameters currently displayed on the display as the target sign parameters, or it can use the sign parameters currently displayed and the signs to be displayed The parameters are used as target physical parameters.

Second, how to determine the freezing time period based on the freezing instruction in the voice signal.

After receiving the voice signal, the processor parses the voice signal to obtain a freezing instruction, and judges whether the freezing instruction contains a time parameter related to the freezing time period. If included, the processor determines the freezing period according to the time parameter; if not included, the processor obtains the preset freezing period, and determines the period of the preset freezing period before or after the time when the freezing instruction is received as the freezing period period. Among them, the processor parses the freezing instruction from the received voice signal, which means that the processor receives the freezing instruction.

Specifically, the user can pre-set the medical equipment according to actual needs, set the default freezing time, and set whether to freeze the graphics data before the receiving time point after receiving the freezing instruction, or whether to freeze the graphics after the receiving time point The data is frozen. Therefore, when the processor determines that the freezing instruction does not include a time parameter, it uses the above-mentioned preset content as a time point at which the freezing instruction is received, and determines the freezing time period from the time point. The time endpoint is used as the end time point to determine the freezing time period forward. Regardless of whether the freezing period is determined before or after, the length of the freezing period is the aforementioned preset freezing period.

For example, the processor receives the voice signal at 10:35:00, and extracts the freezing instruction "freeze blood oxygen" from the voice signal. The processor determines that the freezing instruction does not contain a time parameter, and then obtains the setting data. The setting data indicates that the time period after the freezing instruction is regarded as the freezing time period, and the freezing time is 2 minutes, then the processor determines that the freezing time period is a time from 10:35:00 to 10:37:00. segment.

The voice signal may include a time parameter for indicating the freezing time period. If the processor determines that the freezing instruction includes a time parameter, it determines the freezing time period according to the time parameter.

For example, if the freezing instruction includes the freezing duration, the processor determines the freezing duration before or after the time point when the freezing instruction is received as the freezing duration.

Specifically, the user may clearly indicate the length of time for freezing in the voice signal. For example, the user’s voice signal is "freeze for 3 minutes", so that after the processor parses the freeze instruction from the voice signal, it uses the length of time in the freeze instruction as the freeze The duration of the time period. The time point at which the freezing instruction is received can be used as the start time end point of the freezing time period or the end time end point of the freezing time period. Which one can be set by default by the system? For the setting method, please refer to the above-mentioned setting instructions without time parameters, which will not be repeated here.

Of course, the user may also clearly indicate the relationship between the freezing time period and the current time point in the voice signal. For example, the voice signal is "3 minutes after freezing", which means that it is necessary to freeze the graphics data 3 minutes after the current time point. "Freeze 3 minutes before" means that it is necessary to freeze the graph data 3 minutes before the current time point. In this case, after the processor parses the freeze instruction from the voice signal, it can follow the instructions of the freeze instruction to use the time point at which the freeze instruction is parsed as the end point, and take a period of time before or after it as the freeze period .

For another example, if the freeze instruction includes a start instruction and an end instruction, the processor determines the time period from the time point when the start instruction is received to the time point when the end instruction is received as the freeze time period.

Specifically, the user may find that the graphic data is abnormal at a certain point in time, and then input a voice signal to the medical device at the point in time as "free freeze start". When the graphic data is found to be normal or the user decides to end the freezing, Input a voice signal to the medical device as "freeze end". After the processor receives the voice signal, if the start instruction is parsed from the voice signal, it starts to freeze the graphics data; if the end instruction is parsed from the voice signal, the freeze of the graphics data is ended. In this implementation manner, the user designates to freeze a graphic segment of any length of time, and the freezing time period starts from the time when the start instruction is received and ends when the end instruction is received. It should be noted that in this case, although the time parameter is not clearly indicated in a voice command, the combination of two voice commands implicitly indicates the time parameter, that is, the freezing time is limited by the start voice command and the end voice command segment. The above illustrates a situation, that is, a single voice signal does not carry a time parameter, and the preset duration is obtained as the freezing time period. In order to distinguish from this situation, two different freezing instruction formats can be preset. Enter the corresponding freeze instruction in the format.

For another example, if the freezing instruction includes a start time point and an end time point, the time period between the start time point and the end time point is determined as the freezing time period.

Specifically, if the user finds that a certain graphic segment in the graphic data is abnormal, he can also clearly indicate the time point of freezing start and the time point of freezing end in the voice signal, for example, the voice signal is "5:30:21, 5 35 minutes and 21 seconds." After the processor parses out the freeze instruction from the voice signal, it uses the smaller time point in the freeze instruction as the start time point, the larger time point in the freeze instruction as the end time point, and calculates the time between the two time points. The time period is determined as the freezing time period.

It should be noted that in order to facilitate the user's voice input, some time elements can be omitted from the voice. For example, if it is necessary to freeze the graphic data in the current hour, the time parameter input by the user may not include an indication about the hour. For example, the voice signal is "30 minutes 21 seconds, 35 minutes 21 seconds", and the processor parses this After the type of time parameter, the hour of the current time point is added as the hour element by default. To further facilitate the user’s voice input, the user does not need to input the name of a certain time element, and the processor parses the previous level of the value of the default time element, and automatically supplements the value of the previous level of time element. First-level time element. For example, the voice signal input by the user is "30 minutes 21, 35 minutes 21". After the processor analyzes the voice signal and finds the value "21" as the default time element, it will automatically add the next level time element of "分". second". The default input of other time elements is processed similarly, so I won’t repeat them here.

It should be noted that although the methods for determining the target physical parameters and the freezing time period are separately described above, it does not mean that the two information items are input into the medical device through different voice signals. The user can indicate both the parameter identification used to determine the target physical parameter and the time parameter of the freezing period in a voice signal. For example, the voice signal is "freeze blood oxygen for 3 minutes", "start freezing ECG, end freezing ECG" ", "Freeze blood oxygen at 5:30:21, 5:35:21". After receiving the voice signal, the processor parses the voice signal to obtain a freezing instruction, and then determines both the target physical parameter and the freezing time period based on the same freezing instruction.

After determining the target physical sign parameters and the freezing time period, the graphic data corresponding to the target physical sign parameters can be frozen according to the freezing time period instructions to obtain frozen graphic fragments.

It can be seen from the above technical solutions that the medical equipment provided by the present invention includes a display, an audio collection device, a memory, and a processor. The display is used to display the graphic data of the physical sign parameters, and the audio collection device is used to collect the voice signal input by the user and carry the freezing instruction, and send the voice signal to the processor. The processor can run the software program stored in the memory according to the following method Realize the freezing function: According to the freezing instruction in the voice signal, the target physical parameter and the freezing time period are determined, and the graphics segment is frozen in the graphics data according to the two freezing information. It can be seen that using the medical device provided by the present invention, the user can instruct the medical device to freeze the graphic data through a voice signal, which not only simplifies the user's manual operation of the device, improves the user experience, but can also perform sterilization operations to avoid cross-infection. Widely used in the scene.

The frozen graphic fragments can be stored and displayed for users to view. Specifically, the display of the medical device is also used to display frozen graphic fragments. The display can automatically display the graphic segment after freezing the graphic segment, or can also display the frozen graphic segment based on a viewing instruction input by the user.

If the user wants to modify the frozen graphic segment, he can also instruct the medical device to implement the modification function through a voice signal. Specifically, the audio acquisition device is also used to receive a modification instruction to the target graphic segment, wherein the modification instruction is used to indicate the modified freezing time period; the modification instruction is sent to the processor; the processor is also used to transfer the target graphic segment Replace with the graphic segment corresponding to the freezing period indicated by the modification instruction.

Among them, if the user wants to modify the freezing period of a certain graphic segment, the voice signal includes the identifier of the graphic segment. In addition, the voice signal needs to contain instructions related to modification to indicate that the voice signal contains a modification instruction. For example, if the voice signal is "modify blood oxygen for 5 minutes", the processor can analyze that the voice signal carries a modification instruction, the modification instruction indicates a modified freezing time period, and the specific instruction is the modified freezing time period length of time.

After the processor receives the voice signal and parses the voice signal to obtain a modification instruction, it modifies the target graphic segment indicated by the modification instruction to a graphic segment corresponding to the freezing time period indicated by the modification instruction. For example, modify the frozen blood oxygen pattern segment from 3 minutes to 5 minutes.

The medical equipment described above mainly implements the function of freezing the graphic segments based on the instructions of the voice signal. Of course, the present invention also provides a medical device, which allows the user to indicate the realization of the freezing function through gestures.

As shown in FIG. 2, the medical equipment may specifically include: a display 201, an image acquisition device 202, a memory 203, and a processor 204. Among them, the processor 204 is respectively connected to the display 201, the image acquisition device 202, and the memory 203. It should be noted that the structure of the medical device and the implementation of each device module are similar to the medical device shown in FIG. 1 above, and will not be repeated here, and only the differences will be briefly described.

The display 201 is used to display graphic data of at least one physical parameter of the monitored object.

The image acquisition device 202 is configured to collect image data input by the user and carrying a freezing instruction, and send the image data to the processor.

Among them, the user can show freezing-related gesture actions to the image acquisition device of the medical equipment, and the image acquisition device can collect image data including freezing-related gesture actions, and send the image data to the processor. The image acquisition device may specifically be a camera.

The memory 203 is used to store software programs and data.

The processor 204 is configured to execute at least the following steps by running a software program stored in the memory and calling data stored in the memory: determining freezing information based on a freezing instruction in the image data, the freezing information at least including: frozen target physical parameters And the freezing time period; in the graphic data of the target physical sign parameter, the graphic fragment corresponding to the freezing time period is obtained; the graphic fragment is frozen.

In one implementation, the processor executes the step of determining the target sign parameters based on the freezing instruction in the image data. The specific process is: judging whether the freezing instruction includes the sign parameter identification; if the freezing instruction includes the sign parameter identification, the sign The physical sign parameter indicated by the parameter identification is determined as the target physical parameter; if the physical parameter identification is not included in the freezing instruction, all the displayed physical parameters are taken as the target physical parameter.

Among them, after the processor receives the image data, it can use image processing technology to analyze the image data. If the analysis result contains gestures related to freezing, it means that the image data carries a freezing instruction. The freezing instruction can indicate the physical parameters that you want to freeze, and the specific implementation methods can include the following.

One implementation is that the correspondence between the gesture action and the physical sign parameter identifier can be preset, and the user wants to freeze a certain physical parameter, and then inputs the gesture action corresponding to the physical parameter identifier. For example, the preset gesture "2" means to freeze the graphic data of the second characteristic parameter displayed on the display.

Another implementation is that the correspondence between the gesture action and the opening menu can be preset, and after the corresponding gesture action is parsed from the image data, a menu containing one or more physical parameter options is provided. The user instructs one or some physical parameter identifications through gesture actions. For example, the user shows the gesture action of drawing a circle to the image acquisition device, and after the processor parses the gesture action of the circle from the image data collected by the image acquisition device, the physical sign parameters displayed on the display can be included in the menu and provided to the user. The physical sign parameters in the menu may have numbers, and the user can indicate the selected physical sign parameters through gesture actions corresponding to the numbers. For example, the user draws a track of the number "2" or displays a gesture indicating "2" (such as showing two fingers) to prompt the selection of the physical parameter numbered 2.

In one implementation, the processor executes the step of determining the freezing time period based on the freezing instruction in the image data. The specific process is: if the freezing instruction includes the freezing duration, the freezing duration will be frozen before or after the time point when the freezing instruction is received. The time period is determined as the freezing time period; if the freezing instruction includes a start instruction and an end instruction, the time period between the time when the start instruction is received and the time when the end instruction is received is determined as the freezing time period; If the freezing duration is not included in the instruction, the preset freezing duration is obtained, and the duration of the preset freezing duration before or after the time point when the freezing instruction is received is determined as the freezing duration.

Wherein, the freezing instruction includes the freezing duration in a way that the user can indicate the freezing duration through a gesture action, for example, gestures for the freezing duration number, or showing a gesture indicating the freezing duration number. Specifically, for example, the user draws a track of the number "3" or displays a gesture indicating "3" (such as showing three fingers) to prompt that the freezing time is 3 minutes.

The freezing instruction includes the start instruction and the end instruction in a manner that the gesture actions corresponding to the start instruction and the end instruction are respectively set in advance, and the user inputs the corresponding gesture actions according to the corresponding relationship. For example, the start instruction is to draw a circle, the end instruction is to draw a triangle, and so on.

In addition, the processor can also be used to start the image acquisition device if a freeze start instruction is received.

In addition, the medical equipment may also include: a photoelectric sensor device or a freeze button; the way the processor receives the freeze start instruction includes any of the following methods: if the photoelectric sensor device detects a light change that meets the preset requirements, Generate a freeze start instruction and send it to the processor; if the freeze button receives a trigger operation, generate a freeze start instruction and send it to the processor; if a device start instruction is received, it is determined to receive a freeze start instruction; The monitoring start command of the object is confirmed to receive the freezing start command.

In addition, the processor can also be used to display frozen graphics fragments.

In addition, the image acquisition device may also be used to receive a modification instruction to the target graphic segment, where the modification instruction is used to indicate the modified freezing time period; the modification instruction is sent to the processor; the processor is also used to replace the target graphic segment It is the graphic segment corresponding to the freezing time period indicated by the modification instruction.

The above medical equipment can meet the needs of users to realize the freezing function through gesture actions. In addition, the present invention can also provide a medical device, and the user can control the medical device to realize the freezing function through voice and gesture actions. The medical equipment specifically includes: a display, an audio acquisition device, an image acquisition device, a memory, and a processor. Among them, the processor is respectively connected with a display, an audio acquisition device, an image acquisition device and a memory.

Specifically, the audio collection device can collect the user's voice signal, and the image collection device can collect the image data input by the user including gesture actions, so the user can input part of the freezing instruction through the voice signal, and input part of the freezing instruction through the gesture action. The two types of freezing instructions together instruct the medical equipment to complete the freezing function. The processor is used to determine the freezing information based on the freezing instruction in the voice signal and the freezing instruction in the image data. The freezing information includes at least: frozen target sign parameters and freezing time period; in the graphic data of the target sign parameters, the freezing time is obtained Segment corresponding to the graphic segment; freeze the graphic segment.

One implementation manner is that the user can use a voice signal to input a freeze instruction to open a menu containing physical sign parameters, and use a gesture action to indicate the selected physical sign parameter identification. Another implementation manner is that the user can use a voice signal to input the target physical sign parameter identification, and use a gesture action to indicate the freezing time period. For example, the user inputs a voice signal "Freeze ECG" and uses a gesture action to indicate "3" to indicate to freeze a 3-minute waveform segment of each channel of the ECG. Or, it may also include other examples of the combination of voice signals and gesture actions that those skilled in the art can think of.

In the process of patient vital signs monitoring, the frozen graphic fragments can provide data support for monitoring abnormality analysis. For example, medical staff can analyze the frozen graphic fragments to determine the cause of abnormal physiological signs of the patient. In practical applications, the analysis of frozen graphic fragments by medical staff usually includes measurement of frozen graphic fragments and superimposed comparison viewing.

See Figure 3, which shows the structure of a medical device provided by the present invention. As shown in FIG. 3, the medical device may specifically include: a display 301, an input device 302, a memory 303, and a processor 304, wherein the processor 304 is connected to the display 301, the input device 302, and the memory 303, respectively.

The display 301 is used to display graphic segments of the physical parameters; and to display measurement tools.

Among them, the graphic segment displayed on the display is a frozen graphic segment. After the graphic segment is displayed to the user, the user can use a measuring tool to measure the geometric characteristics of the graphic segment. The graphic segment can be any type of graphic segment that can be understood and expected by those skilled in the art, for example, it can specifically include: an electrocardiogram waveform segment, a respiratory waveform segment, or a blood pressure waveform segment.

The input device 302 is configured to receive a measurement start instruction input by a user, and send the measurement start instruction to the processor.

The user can input a measurement start instruction to the medical device through the input device, and the measurement start instruction received by the input device will be sent to the processor, so that the processor can start the measurement function of the graphic segment.

Specifically, the input device may include an audio capture device or an image capture device. The audio collection device is used to collect the voice signal input by the user and carries the measurement start instruction; the image collection device is used to collect the gesture action input by the user and the measurement start instruction is carried. It can be seen that in the case that the medical equipment includes an audio collection device, the user can control the medical device to initiate measurement by voice; in the case that the medical device includes an image capture device, the user can control the medical device to initiate measurement through gesture actions.

The user input a voice signal carrying a measurement start instruction, which can include the following examples: for example, the user inputs a voice signal "measure"; in addition, the realization of the measurement function needs to depend on the measurement tool, so the user can input the voice including the name of the measurement tool Signals, such as "caliper gauge", "angle gauge", etc. Among them, "caliper" corresponds to a length measuring tool, which is used to measure the distance or length between two points; "angle gauge" corresponds to an angle measuring tool, which is used to measure the distance between two lines Angle and/or slope of the line.

The user input of the gesture action carrying the measurement start instruction specifically includes: the gesture action corresponding to the measurement start instruction can be predefined, and the user only needs to input the corresponding gesture action. For example, the gesture action corresponding to the measurement start instruction can be drawing a triangle, and so on.

Alternatively, the input device may also include a touch-sensitive display, and the user may perform a touch-sensitive operation on the graphic segment of the physical parameter. The touch-sensitive display generates a measurement start instruction and sends it to the processor in response to the touch operation. For example, the user can long-press, click, or double-click a certain graphic segment to trigger the touch-sensitive display to generate a measurement start instruction.

The memory 303 is used to store software programs and data.

The processor 304 is configured to execute at least the following steps by running a software program stored in the memory and calling data stored in the memory: in response to the measurement start instruction, generating a measurement tool indicated by the measurement start instruction, where the measurement tool is used for Measure the geometric characteristics of the lines in the graphic fragment.

Among them, after the measurement start instruction is sent to the processor, the processor generates a corresponding measurement tool. The specific measurement tool generated by the processor can be determined by the measurement start instruction. For example, the measurement start instruction may include the name of the measurement tool, such as "caliper" or "angle gauge", so that the processor generates the corresponding measurement tool. For another example, if the measurement start instruction does not include the name of the measurement tool, the processor generates the set measurement tool according to the default setting. For example, the default setting is to generate a length measurement tool, generate an angle measurement tool, or generate a menu containing one or more measurement tool selection items. If the processor generates a selection menu, the processor generates a corresponding measurement tool based on the user's selection.

The relevant data of the measurement tool generated by the processor is sent to the display. While displaying the graphic segment, the display also displays the measurement tool based on related data, so that the user can control the measurement tool to measure the geometric characteristics of the line in the graphic segment.

Specifically, geometric features include any one or more of the following items: the horizontal distance between two points in the line, the vertical distance between two points in the line, the slope of the two points in the line, the connection between the two points in the line and the horizontal line The angle between. Among them, a single length measurement tool can be used to measure horizontal distance and vertical distance; an angle measurement tool can be used to measure slope and angle; and a measurement tool combined with multiple length measurement tools can also be used to measure slope and angle.

The user can control the measurement tool to measure specific lines in the graphic segment. In order to realize this control function, the display of the medical device may be specifically a touch-sensitive display to receive the user's control gestures.

It should be noted that the displayed measurement tool may include at least one measurement controllable end. As shown in Figure 4, the length measurement tool includes a measurement line and two measurement controllable ends. The measurement controllable ends are the two end points of the measurement line. The user can drag the measurement controllable end to change the length and position of the length measurement tool ; The angle measurement tool includes two measurement lines and three measurement controllable ends. The measurement controllable end includes the intersection of two measurement lines and the other two end points of the two measurement lines. Similarly, the user can also drag the measurement controllable End to change the angle measuring tool to measure the length and position of the line.

Based on the user's movement operation on the measurement controllable terminal on the touch-sensitive display, the touch-sensitive display is also used to receive the user's movement instruction to the measurement controllable terminal and send the movement instruction to the processor. The processor is also used to determine the target position indicated by the movement instruction according to the movement instruction, and send the target position to the touch-sensitive display. The touch display is also used to display the measurement controllable end at the target location. It can be seen that, based on this technical solution, the medical device can achieve the purpose of touch control of the measurement tool by the user. If the user wants to use the measuring tool to measure the geometric characteristics of which line in the graphic segment, he can control the corresponding measuring tool on the touch-sensitive display and move the measuring tool to the corresponding position.

Further, the processor is also used to measure the geometric characteristics of the lines in the graphic segment by using a measuring tool that measures the controllable end at the target position; and sends the geometric characteristics to the display; the display is also used to display the geometric characteristics.

The following examples illustrate the measurement process of the length measurement tool and the angle measurement tool.

As shown in FIG. 5A, the user can control the positions of the two end points of the length measuring tool on the frozen waveform through two-finger control gestures (such as the thumb and index finger respectively controlling the two end points of a length measuring tool). As the distance between the thumb and index finger increases or decreases, the length measuring tool can become longer or shorter. The adjusted length measuring tool can be horizontal to measure the horizontal distance between two points on the frozen waveform; the adjusted length measuring tool can also be vertical to measure the vertical between two points on the frozen waveform distance. During measurement, the touch-sensitive display can display the current measurement value between two points in real time. For example, the horizontal distance value measured by the length measuring tool 1 in real time is 420ms, and the vertical distance value measured by the length measuring tool 2 in real time is 1.1mV. In addition, the length measuring tool can also be inclined at a certain angle. For example, the thumb or index finger can be used as a fixed point to rotate another finger to adjust the inclination angle of the length measuring tool.

As shown in 5B, the angle measurement tool includes three measurement controllable ends A, B, and O. The user can move point A, point O, and point B to the position to be measured by fingers, and the processor automatically calculates the edge AO relative to The slope value of side BO, and the value of the angle a between side AO and side BO is calculated.

It should be noted that the two length measurement tools can also be combined into one angle measurement tool. The combined length measurement tool is the same as the angle measurement tool and can be used to measure the slope of the line and the angle between the lines. Specifically, the user can call a new length measurement tool through the input device after completing the measurement using a length measurement tool. For example, a new length measuring tool can be displayed by controlling the medical device by the voice signal "create a new caliper".

The user inputs a merge instruction, and the input device is also used to receive the merge instruction input by the user, and send the merge instruction to the processor, where the merge instruction can be realized through voice, non-contact gesture actions, or contact actions such as double-clicking; the processor also uses In response to the merging instruction, an end point of one measurement line is coincident with an end point of another measurement line to generate an angle measurement tool; wherein the angle measurement tool is used to measure the angle and slope of the line composed of two points in the graphic segment.

For example, the display shows a first length measuring tool and a second length measuring tool. The two end points of the first length measuring tool are called point A and point B, respectively, and the two end points of the second length measuring tool are called point C and point B. Point D. The user inputs a merge instruction, and the processor responds to the merge instruction to overlap the point A of the first length measuring tool with the point C of the second length measuring tool, thereby obtaining an angle measuring tool. The combined angle measurement tool can measure slope and angle based on the instructions of the measurement command. The measurement instruction can be generated based on the following input content, such as the user's double-clicking the coincident point operation on the touch-sensitive display screen, and the user inputting the voice signal of "calculate slope and angle".

After the measurement is completed, the user can save the measurement result by confirming the instruction. The confirmation instruction may be a voice instruction, a non-contact gesture action, or a contact action on the touch-sensitive display, such as double-click, click, and so on.

In addition, after the user uses a measurement tool to measure a certain line of the graphic segment, he can also call a new measurement tool through the input device. In this way, the medical device can create multiple measurement tools on a graphic segment, and Use multiple measurement tools to complete the measurement of multiple geometric features of the same graphic segment. Of course, if there are multiple graphic segments displayed, multiple different measurement tools can be used to measure different graphic segments separately.

It should be noted that in the process of measuring the graphic segment, it may be necessary to control the display status of the graphic segment and the condition of the measurement tool. Therefore, the user can also input measurement auxiliary instructions through the input device during the measurement process to achieve auxiliary control of the measurement process.

Specifically, the input device is also used to receive the measurement assistance instruction input by the user, and send the measurement assistance instruction to the processor; similarly, the measurement assistance instruction can be a voice command, a non-contact gesture action, or a touch screen display. Contact action. The processor is also used to perform measurement assistance actions corresponding to the measurement assistance instructions in response to the measurement assistance instructions; wherein the measurement assistance actions include any one or more of the following items: zoom in, zoom out, rotate, and Delete measurement tools, add measurement tools, and merge measurement tools.

In practical applications, medical staff may need to compare multiple graphic fragments, so the multiple graphic fragments need to be superimposed and displayed.

One situation is that the user wants to compare multiple graphic segments of the same physical parameter at multiple different freezing time periods: for example, want to compare a waveform segment of the blood oxygen waveform at 10:50 and a segment at 11:50 Waveform fragments, for another example, want to compare QRS waveform fragments of ECG II lead waveforms in multiple different time periods. For ease of understanding, this contrast can be called horizontal contrast.

Another situation is that the user wants to compare multiple graphic clips with different physical parameters in the same freezing time period, for example, wants to compare Art waveform clips and CVP waveform clips in the same time period. For ease of understanding, this contrast can be called longitudinal contrast.

The user inputs an overlay instruction to the medical device, and the overlay instruction can indicate the graphic segments that need to be overlaid. For ease of description, these graphic segments can be referred to as target graphic segments. The input device is also used to receive the superimposing instruction input by the user, and send the superimposing instruction to the processor; the processor is also used to respond to the superimposing instruction, and perform upper and lower layers on the target graphic fragment indicated by the superimposing instruction in the same display area The overlap result is sent to the display; the display is also used to display the overlap result.

As shown in FIG. 6A, two waveform segments of different time periods are cut from the waveform of the same physical parameter, and the waveform segment 1 and the waveform segment 2 are superimposed on the same display area according to the superimposition instruction input by the user. As shown in Fig. 6B, the Art waveform fragments and the CVP waveform fragments collected in the same time period are superimposed.

It should be noted that the superimposition instruction can be realized through voice, non-contact gesture action, and contact action. In one implementation, the superimposition instruction can be implemented by one instruction. For example, a medical device can display graphic fragments of multiple physical sign parameters in the same time period, and the user can input a voice signal "Superimpose Art CVP", and the medical device superimposes the graphic fragments of the two physical sign parameters Art and CVP. In another implementation, the superimposed instruction can be implemented by multiple instructions. For example, the user inputs a voice signal to "superimpose" and then selects multiple graphic segments to be superimposed on the touch-sensitive display, and the medical device responds to the two superimposing instructions to superimpose the multiple graphic segments selected by the user.

Further, the user can also trigger the above-mentioned measurement function and use the measurement tool to measure the geometric characteristics of the superimposed graphic fragments. The measurement process is not repeated here.

In addition, users can also add annotations to the measurement results of the graphic fragments, such as time, operator, and so on. Specifically, the input device is also used to receive the annotation content about the geometric feature input by the user, and send the annotation content to the processor; the processor is also used to associate the geometric feature with the annotation content and save it.

The graphic fragments superimposed above are all graphic fragments for a single sign parameter. In practical applications, users also expect to compare and analyze multiple sign parameters at multiple different time periods at the same time. Therefore, multiple physical sign parameters can be formed into a composite form of graphics, and then multiple composite graphics can be superimposed.

In order to achieve this function, the present invention provides a medical device, which may include: an input device, a processor, and a display.

The input device is used to receive the superimposition instruction input by the user, and the superimposition instruction includes multiple target physical parameters and multiple target time points; the superimposition instruction is sent to the processor; the processor is used to obtain each target in response to the superimposition instruction The parameter values of the physical sign parameters at each target time point; for each target time point, a geometric figure is generated according to all the parameter values corresponding to the target time point, such as a spider diagram; the centers of the geometric figures at different target time points are overlapped , Get the overlapping graphics; send the overlapping graphics to the display; the display is used to display the overlapping graphics.

It should be noted that the distance between the corner and the center point in the geometric figure is determined by the parameter value. Therefore, the geometric figures generated by different parameter values of the same target physical parameter are different. By superimposing different geometric figures, the difference between different parameter values of the same target physical parameter can be analyzed.

Specifically, the user can realize the superposition of composite graphics through voice signals or gesture actions. Therefore, the input device may specifically include: an audio collection device or an image collection device. The audio collection device is used to collect the superimposition instructions input by the user through voice signals; the image collection device is used to collect the superimposition instructions input by the user through gesture actions.

For example, the voice signal input by the user is "superimposition parameters CI, ScvO2, pArt-M, SVRI, SVV, compared today at 11:00 and 12:00." After receiving the voice signal, the processor parses the voice signal to obtain a superimposition instruction. According to the instructions of the superimposed instruction, obtain the parameter values of the six parameters at 11 o'clock in the current day and the parameter values at 12 o'clock in the current day, generate a pentagonal diagram from the six parameter values at 11 o'clock, and convert the six parameter values at 12 o'clock Generate a pentagonal graph. Then overlap the center points of the two pentagonal graphs to obtain a superimposed graph and display it. The display effect is shown in Figure 6C. It should be noted that, in order to facilitate the user's voice control, the target physical parameters used to generate the geometric figure may be preset, and the user's voice signal only needs to include the time period that needs to be compared.

The data processed above are all graphical data, such as trend graphs and waveform graphs. The invention can also process the image data of the monitored object. Existing image data processing methods require medical personnel to input control instructions by contacting medical equipment such as pressing physical buttons. In order to simplify the operation mode of the medical staff, the present invention provides a medical device, which can provide the medical staff with a voice control function, and the medical staff controls the image data processing process through voice.

See Figure 7, which shows the structure of a medical device provided by the present invention. Specifically, the medical equipment may include: a display 701, an audio collection device 702, a memory 703, and a processor 704. The processor 704 is respectively connected to the display 701, the audio collection device 702 and the memory 703.

The display 701 is used to display a monitoring image of the physiological system of the monitored object; the monitoring image may specifically include a three-dimensional image of the heart, an image of the respiratory system, or an image of the blood circulation system.

The audio collection device 702 is used to receive a voice signal carrying an image processing instruction input by the user, and send the voice signal to the processor; wherein the image processing instruction may specifically include an image adjustment instruction, and the image adjustment instruction includes: image reduction, image Zoom in, image rotation, increase in image change rate, or decrease in image change rate. The rate of image changes, such as heart rate, lung breathing rate, etc.

The memory 703 is used to store software programs and data.

The processor 704 is configured to execute at least the following steps by running a software program stored in the memory and calling data stored in the memory: processing the monitoring image in accordance with the processing mode indicated by the image processing instruction in the voice signal; and The processed monitoring image is sent to the display, so that the display 701 displays the processed monitoring image.

In a specific implementation, the image processing instruction may specifically be an image freezing instruction, and the image freezing instruction is used to indicate a freezing area, such as a voice instruction to freeze a heart area in a circulatory system. It should be noted that the monitoring image displayed on the display can be real-time monitoring data. If the physiological state of the monitored object is different, the displayed image data is also different. In other words, the monitor image displayed on the monitor changes in real time. After the processor receives the image freezing instruction, it intercepts the monitoring image of the frozen area at the point in time when the voice signal is received to obtain the intercepted monitoring image. The captured monitoring images are frozen image data.

It should be noted that the function of freezing image data can also be implemented by contact gestures. Specifically, the display is a touch-sensitive display, and the user can select an area by sliding the track among the image data displayed on the touch-sensitive display, and the processor freezes the image data corresponding to the area.

The frozen image data can be used for further analysis. In order to facilitate analysis and processing, the frozen image data can also be further adjusted, such as zooming out, zooming in or rotating.

Therefore, the audio collection device is also used to receive a voice signal carrying an image adjustment instruction input by the user, and send the voice signal to the processor, where the image adjustment instruction includes: an image reduction instruction, an image enlargement instruction or an image rotation instruction; processing The monitor is also used to adjust the intercepted monitoring image according to the instruction of the image adjustment instruction in the voice signal, and send the adjusted monitoring image to the display; the display is also used to display the adjusted monitoring image.

Similarly, the above-mentioned adjustment of the frozen monitoring image can also be realized by contact gestures, such as a two-finger zoom-out gesture for an image reduction instruction, a two-finger widening distance gesture for an image zoom-in instruction, a one-finger circle gesture for an image rotation instruction, etc .

In practical applications, the frozen area may also be associated with physical sign parameter measurement data, and the associated physical sign parameter measurement data can also be displayed along with the intercepted monitoring image. Specifically, the processor is also used to acquire physical parameter measurement data related to the frozen area of the monitored object, and send the physical parameter measurement data to the display; the display is also used to display the physical parameter measurement data.

For example, as shown in Figure 8A, in the circulatory system monitoring image, the image of the heart part is captured (the part selected by the circle represents the captured image), and this part of the image has a correlation with the peripheral vascular resistance index SVRI, a physical parameter, so as As shown in FIG. 8A, the display result includes not only the intercepted monitoring images, but also the trend graph of the peripheral vascular resistance index in the past period of time, such as 15 minutes.

Further, if the physical sign parameter measurement data includes: a trend graph of the physical sign parameter corresponding to the frozen area within a preset time period; the user can also zoom and adjust the trend graph through voice.

Specifically, the audio collection device is also used to receive a voice signal input by the user carrying a trend graph zoom instruction, and send the voice signal to the processor; the processor is also used to follow the trend graph zoom instruction instruction in the voice signal, The trend graph is zoomed in the measurement time dimension and/or the measurement value display range dimension, and the zoomed trend graph is sent to the display; the display is also used to display the zoomed trend graph.

Among them, the trend chart includes two dimensions, measurement duration and measurement value display range. See the peripheral vascular resistance index trend graph shown in Figure 8B. According to the measurement time dimension of the trend graph, the measurement duration of the trend graph is 15 minutes, the measurement value display range is 1000 to 3500, and the measurement value display range can also be called the measurement value. Amplitude scale.

There are two types of zoom adjustment. One is to zoom in the measurement time dimension, such as extending or reducing the measurement time; the other is to zoom in the measurement value display range dimension, if the measurement value display range is expanded or reduced. Similarly, the above adjustment of the trend graph can also be realized by contact or non-contact gestures.

In order to realize the control of monitoring images through non-contact gestures, the present invention provides the following medical equipment. specifically:

A medical equipment includes a display, an image acquisition device and a processor.

The processor is used to execute at least the following steps by running the software program stored in the memory and calling the data stored in the memory: performing the monitoring image on the monitoring image according to the processing mode indicated by the image processing instruction in the image data Processing; and sending the processed monitoring image to the display.

In one implementation, the image processing instruction includes an image adjustment instruction, where the image adjustment instruction includes: image reduction, image enlargement, image rotation, image change rate increase, or image change rate reduction. Image processing instructions can be expressed by gesture actions, such as an action that decreases the distance between two fingers indicates an image reduction instruction, an action that increases the distance between two fingers indicates an image enlargement instruction, an action that draws a circle indicates an image rotation instruction, and an upward finger movement indicates an image change The speed increase command and the downward motion of the finger indicate the image change speed reduction command.
