[0002] The main function of the monitor is to collect the patient's physiological signals, process and analyze the physiological signals, and finally display the physiological signals on the display screen, and issue different types of alarms based on the physiological signals of specific situations. As a direct medium for medical staff to observe the patient's physiological state, the display of physiological signals is one of the core functions of the monitor.

[0003] With the continuous development of medical technology, more and more types of physiological signals can be monitored, the analysis and indication functions for physiological signals are becoming more and more abundant, the monitoring of patients' physiological status is becoming more and more comprehensive, and more and more content needs to be displayed. Monitors need to further expand their display capabilities based on existing systems, which usually means providing more display screens or providing more display interfaces that can be connected to external display screens to display more different images.

[0004] One implementation solution that comes to mind is to use a core processor with more powerful display performance and support for more display interfaces.

[0023] In order to make the purpose, technical scheme and advantages of the present invention more obvious, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the present invention.

[0024] Figure 1 FIG. 2 shows a schematic structural block diagram of a medical system according to an embodiment of the present application. Figure 1 As shown, the medical system 100 includes a first device 110 and at least one second device 120 that is communicatively connected to the first device 110. The first device 110 is a monitor, including a signal conversion module 111, a signal processing module 112, a display processing module 113, and a display 114; the second device 120 is a device formed by removing the function of processing raw data from the monitor, including a display processing module 123 and a display 124. The display processing module 113 of the first device 110 is the same as the display processing module 123 of the second device 120.

[0025] Among them, the signal conversion module 111 of the first device 110 receives the original data representing the physiological signs parameters of the human body collected by at least one sensor, and converts the original data from an analog signal to a digital signal; the signal processing module 112 of the first device 110 analyzes the digital signal and generates processing result data according to the analysis result; the display processing module 113 of the first device 110 converts the processing result data into a first display signal; the display 114 of the first device 110 displays the information corresponding to the first display signal; the second device 120 directly obtains the processing result data from the first device 110, or, when the second device 120 also includes a signal processing module, the signal processing module 122 of the second device 120 analyzes the digital signal transmitted by the first device 110, and generates processing result data according to the analysis result; the display processing module 123 of the second device 120 converts the processing result data into a second display signal; the display 124 of the second device 120 displays the information corresponding to the second display signal.

[0026] Wherein, the digital signal is analyzed, and the processing result data is generated according to the analysis result, including: generating a waveform curve based on the change of the value of the parameter represented by the digital signal over time; determining whether the value of the parameter represented by the digital signal exceeds the preset safety range. For example: if the value of some parameters exceeds the preset range and an alarm message needs to be output, then the value of the parameter and the alarm message are both processing result data; for another example, the change of some parameters over time can generate a waveform curve, and the waveform curve is used as the processing result data, etc.; or, the value of the parameter itself is the processing result data. The difference between the processing result data and the display signal is that: for example, for the information that the heart rate is 60, the corresponding processing result data is the digital expression of the information 60, corresponding to a certain digital form (can use binary, decimal, or ASCII code and other expression forms, regardless of the image expression form); and the display signal is the image expression of the information 60, corresponding to the image pixel information (the image 60 and its background image may occupy 100x100 pixels, or may occupy 500x300 pixels, and may be displayed in green or red). The processing result data is usually small in size. For example, the number 60 can be expressed using only 1 to 2 bytes. Transmitting the processing result data does not require a large transmission channel bandwidth. Display signals usually have a large amount of data. In the case of non-compression, the larger the image, the larger the display signal data volume, and the larger the transmission channel bandwidth required by the display signal. The transmission channel bandwidth occupied by the display signal is usually several orders of magnitude larger than the transmission channel bandwidth occupied by the processing result data.

[0027] In the embodiment of the present application, in order to extend the display of the monitor as the first device 110, a second device 120 is used in addition to the first device 110. The second device 120 has the same display processing module relative to the first device 110, and both can convert the data to be displayed (processing result data) into a display signal, and display it by their respective displays. Among them, the processing result data to be displayed can be directly processed by the first device 110 itself and then transmitted to the second device 120, and the second device 120 converts the processing result data from the first device 110 into a display signal. Alternatively, the processing result data to be displayed can also be generated by the second device 120 itself. Specifically, the first device 110 transmits the data before obtaining the processing result data to the second device 120, that is, transmits the digital signal after the original data is converted by analog to digital, and the second device 120 generates the processing result data according to the digital signal, and then converts the self-generated processing result data into a display signal, which is displayed by the display 124 of the second device 120. Therefore, based on such a second device 120 and the interaction between the second device 120 and the first device 110, a medical system 100 is formed to achieve an extended display of the first device 110.

[0028] In this extended display solution, since the second device 120 has the same display processing module as the first device 110, that is, the software and hardware (wherein the software and hardware may generally include one or several printed circuit boards PCBA, and interconnecting cables, including devices such as processors, power supplies, and executable programs) used by the second device 120 to implement the display processing module are the same as the software and hardware used by the first device 110 to implement the display processing module, the second device 120 can be obtained by reusing the same software and hardware design based on the existing software and hardware design of the first device 110. Therefore, such an extended display solution does not require changes to the existing software and hardware design of the first device 110, and does not require replacement of the processor and investment of more resources for redevelopment. As long as the existing software and hardware design of the first device 110 is reused, the extended display of the first device 110 can be realized. It has strong versatility and unlimited scalability, and is completely not limited by the performance and resource conditions of a single processor. Moreover, since the second device 120 does not include the function of processing raw data of the first device 110 (monitor), the second device 120 is a device without the function of processing raw data of the monitor. Therefore, the second device 120 has a lower cost than the first device 110, so that the cost of extended display can also be lower.

[0029] exist Figure 1 In the figure, for simplicity, only one second device 120 is shown. In practice, the medical system 100 may include more second devices 120 to meet greater display expansion requirements.

[0030] Combine the following Figures 2 to 5 describe Figure 1 Different examples of interactions between the first device 110 and the second device 120 in the medical system 100 are shown.

[0031] Figure 2 Shows Figure 1 The medical system 100 is shown as an example in which the first device 110 directly sends the processing result data to the second device 120. Figure 2 As shown, the signal conversion module 111 of the first device 110 receives the raw data representing the physiological sign parameters of the human body collected by at least one sensor, and converts the raw data from an analog signal to a digital signal. The signal processing module 112 of the first device 110 analyzes the digital signal and generates processing result data according to the analysis result. The processing result data can be transmitted to the display processing module 113 of the first device 110 and the display processing module 123 of (one or more) second devices 120 simultaneously or in time-sharing through the transmission link. Among them, the display processing module 113 of the first device 110 converts the processing result data into a first display signal, and the first display signal is transmitted to the display 114 of the first device 110, so that the display 114 of the first device 110 displays the information corresponding to the first display signal. The display processing module 123 of the second device 120 converts the processing result data into a second display signal, and the second display signal is transmitted to the display 124 of the second device 120, so that the display 124 of the second device 120 displays the information corresponding to the second display signal.

[0032] Among them, the processing result data transmitted to the display processing module 113 of the first device 110 and the processing result data transmitted to the display processing module 123 of the second device 120 can be the same or different, depending on the application requirements. For example, the customer needs to view information at a relatively far distance from the display 114, so the display 124 of the second device 120 needs to be used. At this time, the processing result data transmitted to the display processing module 113 of the first device 110 and the processing result data transmitted to the display processing module 123 of the second device 120 can be the same, which is convenient for the user to view the information output by the monitor on the display 124 of the second device 120 located at other locations. For another example, the amount of information to be displayed is large, and the display 114 of the first device 110 is not enough to display all the information. At this time, the processing result data transmitted to the display processing module 113 of the first device 110 and the processing result data transmitted to the display processing module 123 of the second device 120 can be different, which is convenient for the user to view different information on the display 114 of the first device 110 and the display 124 of the second device 120.

[0033] In order to distinguish each other, the data processed by the display processing module 113 of the first device 110 can be referred to as the first data in the processing result data, and the first data is the whole data or part of the processing result data output by the signal processing module 112 of the first device 110; the data processed by the display processing module 123 of the second device 120 is referred to as the second data in the processing result data output by the signal processing module 112 of the first device 110, and the second data is the same as or different from the first data. That is, the display processing module 113 of the first device 110 further generates a first display signal according to the first data in the processing result data, and the first data is the whole data or part of the processing result data; the display processing module 123 of the second device 120 generates a second display signal according to the second data in the processing result data generated by the first device 110, and the second data is the same as or different from the first data.

[0034] Similarly, if there is more than one second device 120 , the processing result data transmitted to different second devices 120 may be the same or different, depending on application requirements.

[0035] In addition, the transmission of the processing result data can be through only one bus, that is, each second device 120 is connected to the same bus. Alternatively, the transmission of the processing result data can also be point-to-point transmission, that is, each second device 120 can use an independent transmission channel. Alternatively, the transmission of the processing result data can also be a combination of the above two forms. Among them, the type of transmission channel can include but is not limited to Ethernet, Controller Area Network (Controller Area Network, referred to as CAN), Universal Asynchronous Receiver / Transmitter (UART), RS232, RS422, RS485, Serial Peripheral Interface (Serial Peripheral Interface, referred to as SPI), Universal Serial Bus (Universal Serial Bus, referred to as USB), PCIe and other wired bus forms. It can also be WiFi, Bluetooth (Bluetooth, referred to as BT), Zigbee and other wireless forms.

[0036] In addition, when converting the processing result data into a display signal, the first device 110 may convert the processing result data into a first display signal based on a first display application requirement, and the second device 120 may convert the processing result data into a second display signal based on a second display application requirement, wherein the first display application requirement and the second display application requirement may be the same or different. That is, the first device 110 and the second device 120 may generate display signals according to their respective display application requirements (such as display layout, etc.) to be applied to different scenarios and meet different needs of users.

[0037] Overall, in Figure 2 In the example shown, the second device 120 only needs to have the same display processing module as the first device 110, and can implement extended display of the first device 110 at a relatively low cost.

[0038] Figure 3 Shows Figure 1 The medical system 100 shown in FIG. 1 is an example of sending the data before the processing result data, that is, the digital signal obtained after the analog-to-digital conversion of the original data, to the second device 120. Figure 3 As shown, the signal conversion module 111 of the first device 110 receives the raw data representing the physiological sign parameters of the human body collected by at least one sensor, and converts the raw data from analog signals to digital signals. The digital signal can be transmitted to the signal processing module 112 of the first device 110 and the signal processing module 122 of (one or more) second devices 120 simultaneously or in time-sharing through the transmission link. Among them, the signal processing module 112 of the first device 110 analyzes the digital signal, generates processing result data according to the analysis result, and transmits the processing result data to the display processing module 113 of the first device 110. The display processing module 113 of the first device 110 converts the processing result data into a first display signal, and the first display signal is transmitted to the display 114 of the first device 110, so that the display 114 of the first device 110 displays the information corresponding to the first display signal. The signal processing module 122 of the second device 120 analyzes the digital signal, generates processing result data according to the analysis result, and transmits the processing result data to the display processing module 123 of the second device 120. The display processing module 123 of the second device 120 converts the processing result data into a second display signal, and the second display signal is transmitted to the display 124 of the second device 120, so that the display 124 of the second device 120 displays the information corresponding to the second display signal.

[0039] Among them, the digital signal transmitted to the signal processing module 112 of the first device 110 and the digital signal transmitted to the signal processing module 122 of the second device 120 may be the same or different, depending on the application requirements. For example, the customer needs to view information at a relatively far distance from the display 114, so the display 124 of the second device 120 needs to be used. At this time, the digital signal transmitted to the signal processing module 112 of the first device 110 and the digital signal transmitted to the signal processing module 122 of the second device 120 may be the same, and then the processing result data generated by the display processing modules of the two are the same, which is convenient for the user to view the information output by the monitor on the display 124 of the second device 120 located at other locations. For another example, the amount of information to be displayed is large, and the display 114 of the first device 110 is not enough to display all the information. At this time, the digital signal transmitted to the signal processing module 112 of the first device 110 and the digital signal transmitted to the signal processing module 122 of the second device 120 may be different, and then the processing result data generated by the display processing modules of the two are different, which is convenient for the user to view different information on the display 114 of the first device 110 and the display 124 of the second device 120.

[0040] In order to distinguish each other, the signal processed by the signal processing module 112 of the first device 110 can be called the first digital signal in the digital signal, and the first digital signal is the whole signal or part of the digital signal output by the signal conversion module; the signal processed by the signal processing module 122 of the second device 120 is called the second digital signal in the digital signal output by the signal conversion module 111 of the first device 110, and the second digital signal is the same as or different from the first digital signal. That is, the signal processing module 112 of the first device 110 further analyzes the first digital signal in the digital signal, generates the first processing result data according to the analysis result, and the first digital signal is the whole signal or part of the digital signal; the display processing module 113 of the first device 110 further generates the first display signal according to the first processing result data; the signal processing module 122 of the second device 120 analyzes the second digital signal in the digital signal transmitted by the first device 110, generates the second processing result data, and the display processing module 123 of the second device 120 generates the second display signal according to the second processing result data, and the second digital signal is the same as or different from the first digital signal.

[0041] Similarly, if there is more than one second device 120 , the digital signals transmitted to different second devices 120 may be the same or different, depending on application requirements.

[0042] In addition, the transmission of digital signals can be carried out through only one bus, that is, each second device 120 is connected to the same bus. Alternatively, the transmission of digital signals can also be point-to-point transmission, that is, each second device 120 can use an independent transmission channel. Alternatively, the transmission of digital signals can also be a combination of the above two forms. Among them, the type of transmission channel can include but is not limited to Ethernet, Controller Area Network (Controller Area Network, referred to as CAN), Universal Asynchronous Receiver / Transmitter (UART), RS232, RS422, RS485, Serial Peripheral Interface (Serial Peripheral Interface, referred to as SPI), Universal Serial Bus (Universal Serial Bus, referred to as USB), PCIe and other wired bus forms. It can also be WiFi, Bluetooth (Bluetooth, referred to as BT), Zigbee and other wireless forms.

[0043] In addition, when converting the processing result data into a display signal, the first device 110 may convert the processing result data into a first display signal based on a first display application requirement, and the second device 120 may convert the processing result data into a second display signal based on a second display application requirement, wherein the first display application requirement and the second display application requirement may be the same or different. That is, the first device 110 and the second device 120 may generate display signals according to their respective display application requirements (such as display layout, etc.) to be applied to different scenarios and meet different needs of users.

[0044] Overall, in Figure 3 In the example shown, the second device 120 only needs to have the same display processing module and signal processing module as the first device 110, and can implement extended display of the first device 110 at a lower cost.

[0045] Figure 4 Shows Figure 1 The illustrated medical system 100 is another example in which the first device 110 sends data before the processing result data, that is, a digital signal obtained after analog-to-digital conversion of the original data, to the second device 120. Figure 4 and Figure 3 The examples shown are generally similar, and for the sake of brevity, their similarities will not be described here, only their differences will be described. Their differences are that Figure 3 In the example shown, the signal processing module 122 of the second device 120 obtains the digital signal from the signal conversion module 111 of the first device 110; in contrast, Figure 4In the illustrated example, the signal processing module 122 of the second device 120 obtains the digital signal from the signal processing module 112 of the first device 110 . Figure 3 In the example shown, the signal processing module 122 and the signal processing module 112 both obtain digital signals from the signal conversion module 111. Therefore, the digital signals obtained by the signal processing modules 112 and 122 of the first device 110 and the second device 120 respectively may be the same. Of course, the signal conversion module 111 of the first device 110 may also be allocated different digital signals to them in advance. Figure 4 In the example shown, the signal output by the signal conversion module 111 is sent to the signal processing module 112, and the signal processing module 112 then transmits the signal to the signal processing module 122. Therefore, the digital signals processed by the signal processing modules 112 and 122 of the first device 110 and the second device 120, respectively, may be different, because the signal processing module 112 of the first device 110 may distribute a part of the digital signal obtained from the signal conversion module to the signal processing module 122 of the second device 120. Of course, the signal processing module 112 of the first device 110 may also only play a forwarding role, transmitting all the digital signals obtained from the signal conversion module to the signal processing module 122 of the second device 120. In this case, the digital signals processed by the signal processing modules 112 and 122 of the first device 110 and the second device 120, respectively, are the same.

[0046] Overall, in Figure 4 In the example shown, the second device 120 only needs to have the same display processing module and signal processing module as the first device 110, and can implement extended display of the first device 110 at a lower cost.

[0047] Figure 5 Shows Figure 1 Another example of the medical system 100 in which the first device 110 sends the processing result data to the second device 120. Figure 5As shown, the signal conversion module 111 of the first device 110 receives the raw data representing the physiological sign parameters of the human body collected by at least one sensor, and converts the raw data from an analog signal to a digital signal. The signal processing module 112 of the first device 110 analyzes the digital signal and generates processing result data according to the analysis result. The processing result data can be transmitted to the display processing module 113 of the first device 110 and the signal processing module 122 of (one or more) second devices 120 simultaneously or in time-sharing through the transmission link. Among them, the display processing module 113 of the first device 110 converts the processing result data into a first display signal, and the first display signal is transmitted to the display 114 of the first device 110, so that the display 114 of the first device 110 displays the information corresponding to the first display signal. The signal processing module 122 of the second device 120 further processes the processing result data to obtain processed processing result data, and the display processing module 123 of the second device 120 converts the processed processing result data into a second display signal, and the second display signal is transmitted to the display 124 of the second device 120, so that the display 124 of the second device 120 displays the information corresponding to the second display signal.

[0048] Here, the processing of the processing result data by the signal processing module 122 of the second device 120 may be simply forwarding, for example, forwarding the processing result data to the display processing module 123 of the second device 120; or, the processing of the processing result data by the signal processing module 122 of the second device 120 may be filtering processing, which can generally be applied to a scenario including multiple second devices 120. For example, assuming that there are two second devices 120, the signal processing module 122 of each second device 120 obtains the same processing result data from the signal processing module 112 of the first device 110, but the signal processing module 122(a) of the first second device 120(A) filters out part of the data from the processing result data to obtain part of the data to be displayed, and the part of the data is processed into a display signal by its display processing module 123(a) and then displayed on its display 124(a). The signal processing module 122(b) of the second second device 120(B) filters out part of the data from the processing result data to obtain part of the data to be displayed. The part of the data is processed into a display signal by its display processing module 123(b) and then displayed on its display 124(b).

[0049] Among them, the processing result data transmitted to the display processing module 113 of the first device 110 and the processing result data transmitted to the signal processing module 122 of the second device 120 can be the same or different, depending on the application requirements. For example, the customer needs to view information at a relatively far distance from the display 114, so the display 124 of the second device 120 needs to be used. At this time, the processing result data transmitted to the display processing module 113 of the first device 110 and the processing result data transmitted to the signal processing module 122 of the second device 120 can be the same, so that the user can view the information output by the monitor on the display 124 of the second device 120 located at other locations. For another example, the amount of information to be displayed is large, and the display 114 of the first device 110 is not enough to display all the information. At this time, the processing result data transmitted to the display processing module 113 of the first device 110 and the processing result data transmitted to the signal processing module 122 of the second device 120 can be different, so that the user can view different information on the display 114 of the first device 110 and the display 124 of the second device 120.

[0050] In order to distinguish each other, the data processed by the display processing module 113 of the first device 110 can be referred to as the first data in the processing result data, and the first data is the whole data or part of the processing result data output by the signal processing module 112 of the first device 110; the data processed by the signal processing module 122 of the second device 120 is referred to as the second data in the processing result data output by the signal processing module 112 of the first device 110, and the second data is the same as or different from the first data. That is, the display processing module 113 of the first device 110 further generates a first display signal according to the first data in the processing result data, and the first data is the whole data or part of the processing result data; the signal processing module 122 of the second device 120 obtains the second data in the processing result data from the signal processing module 112 of the first device 110, and generates the third processing result data according to the second data, and the display processing module 123 of the second device 120 is used to generate a second display signal according to the third processing result data, and the second data is the same as or different from the first data.

[0051] Similarly, if there is more than one second device 120 , the processing result data transmitted to different second devices 120 may be the same or different, depending on application requirements.

[0052] In addition, the transmission of the processing result data can be through only one bus, that is, each second device 120 is connected to the same bus. Alternatively, the transmission of the processing result data can also be point-to-point transmission, that is, each second device 120 can use an independent transmission channel. Alternatively, the transmission of the processing result data can also be a combination of the above two forms. Among them, the type of transmission channel can include but is not limited to Ethernet, Controller Area Network (Controller Area Network, referred to as CAN), Universal Asynchronous Receiver / Transmitter (UART), RS232, RS422, RS485, Serial Peripheral Interface (Serial Peripheral Interface, referred to as SPI), Universal Serial Bus (Universal Serial Bus, referred to as USB), PCIe and other wired bus forms. It can also be WiFi, Bluetooth (Bluetooth, referred to as BT), Zigbee and other wireless forms.

[0053] In addition, when converting the processing result data into a display signal, the first device 110 may convert the processing result data into a first display signal based on a first display application requirement, and the second device 120 may convert the processing result data into a second display signal based on a second display application requirement, wherein the first display application requirement and the second display application requirement may be the same or different. That is, the first device 110 and the second device 120 may generate display signals according to their respective display application requirements (such as display layout, etc.) to be applied to different scenarios and meet different needs of users.

[0054] Overall, in Figure 5 In the example shown, the second device 120 only needs to have the same display processing module and signal processing module as the first device 110, and can implement extended display of the first device 110 at a lower cost.

[0055] In the examples described above, although each display processing module is shown to be connected to a display, it may also be connected to a display interface.

[0056] The above exemplifies the medical system according to the embodiment of the present application. Based on the above description, the medical system according to the embodiment of the present application can realize the extended display of the monitor, and does not need to change the existing software and hardware design of the monitor, does not need to replace the processor and invest more resources in redevelopment, and can realize the extended display of the monitor by reusing the existing software and hardware design of the monitor, which has strong versatility, unlimited scalability and low cost advantages.

[0057] Combine the following Figure 6A method 600 for performing extended display of a medical device according to another aspect of the present application is described. Figure 6 As shown, method 600 may include the following steps:

[0058] In step S610, raw data representing human physiological sign parameters collected by at least one sensor is received, the raw data is converted from an analog signal to a digital signal, the digital signal is analyzed, processing result data is generated according to the analysis result, the processing result data is converted into a first display signal, and information corresponding to the first display signal is displayed on a display of the first device.

[0059] In step S620, the processing result data or digital signal is transmitted to the second device, so that the second device directly obtains the processing result data or generates the processing result data based on the digital signal, and then converts the processing result data into a second display signal through the second device, and displays the information corresponding to the second display signal on the display of the second device, wherein the second device is a device formed after the monitor removes the function of processing raw data.

[0060] The method 600 for performing extended display of medical devices according to an embodiment of the present application is applied to the first device 110 of the medical system 100 described above, and is used to perform extended display of the first device 110. In the above-mentioned embodiment, the structures of the first device 110 and the second device 120 in the medical system 100, as well as the operations of each other, have been described in detail. The method 600 described here also describes the operations of the first device 110 and the second device 120. Therefore, for the sake of brevity, the details are not repeated here, and only some main operations are described.

[0061] In an embodiment of the present application, the step S610 of converting the processing result data into a first display signal further includes: generating a first display signal based on first data in the processing result data, the first data being all or part of the processing result data; the step S620 of the second device converting the processing result data into a second display signal further includes: the second device generating a second display signal based on second data in the processing result data generated by the first device, the second data being the same as or different from the first data.

[0062] In an embodiment of the present application, the step S610 of analyzing the digital signal and generating processing result data according to the analysis result further includes: analyzing the first digital signal in the digital signal and generating first processing result data according to the analysis result, wherein the first digital signal is the entire signal or a part of the signal of the digital signal; the step S610 of converting the processing result data into a first display signal further includes: generating a first display signal according to the first processing result data; the step S620 of the second device generating processing result data based on the digital signal further includes: analyzing the second digital signal in the digital signal transmitted by the first device and generating second processing result data; the step S620 of the second device converting the processing result data into a second display signal further includes: generating a second display signal according to the second processing result data, wherein the second digital signal is the same as or different from the first digital signal.

[0063] In an embodiment of the present application, the conversion of the processing result data into a first display signal described in step S610 further includes: generating a first display signal based on first data in the processing result data, and the first data is all or part of the processing result data; the second device described in step S620 converts the processing result data into a second display signal, further including: obtaining second data in the processing result data from the first device, and generating third processing result data based on the second data, and generating a second display signal based on the third processing result data, and the second data is the same as or different from the first data.

[0064] In an embodiment of the present application, the conversion of the processing result data into a first display signal described in step S610 is performed based on a first display application requirement; the conversion of the processing result data into a second display signal by the second device described in step S620 is performed based on a second display application requirement, wherein the first display application requirement and the second display application requirement are the same or different.

[0065] Based on the above description, the method for extended display of medical equipment according to the embodiment of the present application can realize the extended display of the monitor without changing the existing software and hardware design of the monitor, and does not need to replace the processor and invest more resources in re-development. The extended display of the monitor can be realized by reusing the existing software and hardware design of the monitor, which has strong versatility, unlimited scalability and low cost advantages.

[0066] A medical device provided according to yet another aspect of the present application is described below. Figure 7 FIG. 1 shows a schematic structural block diagram of a medical device according to an embodiment of the present application. Figure 7As shown, the medical device 700 includes a host, which includes a first functional system 710 and at least one second functional system 720 that is communicatively connected to the first functional system 710. The first functional system 710 is a monitoring functional system, including a signal conversion module, a signal processing module, a display processing module, and a display interface; the second functional system 720 is a functional system formed by removing the raw data processing function from the monitoring functional system, including a display processing module and a display interface. The display processing module 713 of the first functional system 710 is the same as the display processing module 723 of the second functional system 720.

[0067] The signal conversion module 711 of the first functional system 710 receives raw data representing human physiological sign parameters collected by at least one sensor, and converts the raw data from an analog signal to a digital signal; the signal processing module 712 of the first functional system 710 analyzes the digital signal and generates processing result data according to the analysis result; the display processing module 713 of the first functional system 710 converts the processing result data into a first display signal; the display connected to the display interface 714 of the first functional system 710 (i.e., the original display of the monitor) displays information corresponding to the first display signal; the second functional system 720 directly obtains the processing result data from the first functional system 710, or, when the second functional system 720 further includes a signal processing module, the signal processing module 722 of the second functional system 720 analyzes the digital signal transmitted by the first functional system 710 and generates processing result data according to the analysis result; the display processing module 723 of the second functional system 720 converts the processing result data into a second display signal; the display connected to the display interface 724 of the second functional system 720 (the additional display for extended display) displays information corresponding to the second display signal.

[0068] Wherein, the digital signal is analyzed, and the processing result data is generated according to the analysis result, including: generating a waveform curve based on the change of the value of the parameter represented by the digital signal over time; determining whether the value of the parameter represented by the digital signal exceeds the preset safety range. For example: if the value of some parameters exceeds the preset range and an alarm message needs to be output, then the value of the parameter and the alarm message are both processing result data; for another example, the change of some parameters over time can generate a waveform curve, and the waveform curve is used as the processing result data, etc.; or, the value of the parameter itself is the processing result data. The difference between the processing result data and the display signal is that: for example, for the information that the heart rate is 60, the corresponding processing result data is the digital expression of the information 60, corresponding to a certain digital form (can use binary, decimal, or ASCII code and other expression forms, regardless of the image expression form); and the display signal is the image expression of the information 60, corresponding to the image pixel information (the image 60 and its background image may occupy 100x100 pixels, or may occupy 500x300 pixels, and may be displayed in green or red). The processing result data is usually small in size. For example, the number 60 can be expressed using only 1 to 2 bytes. Transmitting the processing result data does not require a large transmission channel bandwidth. Display signals usually have a large amount of data. In the case of non-compression, the larger the image, the larger the display signal data volume, and the larger the transmission channel bandwidth required by the display signal. The transmission channel bandwidth occupied by the display signal is usually several orders of magnitude larger than the transmission channel bandwidth occupied by the processing result data.

[0069] In an embodiment of the present application, the medical device 700 is a monitor, and the first functional system 710 included therein can realize the monitoring function of the monitor, and the display connected to the display interface 714 of the first functional system 710 is used to display the information output by the first functional system 710. In order to expand the display of the monitor, a second functional system 720 is added inside the host of the monitor. The second functional system 720 has the same display processing module as the original functional system of the monitor, that is, the first functional system 710, and both can convert the data to be displayed (processing result data) into a display signal, and display it by the display connected to their respective display interfaces. Among them, the processing result data to be displayed can be directly processed by the first functional system 710 itself and then transmitted to the second functional system 720, and the second functional system 720 converts the processing result data from the first functional system 710 into a display signal. Alternatively, the processing result data to be displayed may also be generated by the second functional system 720 itself. Specifically, the first functional system 710 transmits data before the processing result data is obtained to the second functional system 720, that is, transmits the digital signal after the analog-to-digital conversion of the original data. After the second functional system 720 generates the processing result data by itself according to the digital signal, it converts the self-generated processing result data into a display signal, which is displayed by the display connected to the display interface 724 of the second functional system 720. Therefore, based on such a second functional system 720 and the interaction between the second functional system 720 and the first functional system 710, the extended display of the medical device 700 is realized.

[0070] In this extended display solution, since the second functional system 720 has the same display processing module as the first functional system 710, that is, the software and hardware (wherein the software and hardware may generally include one or several printed circuit boards PCBA, and interconnecting cables, including components such as processors, power supplies, and executable programs) used by the second functional system 720 to implement the display processing module are the same as the software and hardware used by the first functional system 710 to implement the display processing module, the second functional system 720 can be obtained by reusing the same software and hardware design based on the existing software and hardware design of the first functional system 710. Therefore, such an extended display solution does not require changes to the existing software and hardware design of the monitor, does not require replacement of the processor and investment of more resources for redevelopment, and can realize the extended display of the monitor by reusing the existing software and hardware design of the original functional system of the monitor. It has strong versatility and unlimited scalability, and is completely not limited by the performance and resource conditions of a single processor. Moreover, since the second functional system 720 does not include the function of processing raw data of the monitor, the second functional system 720 is a device without the function of processing raw data of the monitor. Therefore, the second functional system 720 has a lower cost than the existing functional system of the monitor, so that the cost of expanding the display can also be lower.

[0071] exist Figure 7 In the figure, for the sake of simplicity, only one second functional system 720 is shown. In practice, the medical device 700 may include more second functional systems 720 to meet greater display expansion requirements.

[0072] Combine the following Figures 8 to 11 describe Figure 7 Different examples of interactions between a first functional system 710 and a second functional system 720 in the medical device 700 are shown.

[0073] Figure 8 Shows Figure 7 The first functional system 710 in the medical device 700 directly sends the processing result data to the second functional system 720. Figure 8 As shown, the signal conversion module 711 of the first functional system 710 receives the raw data representing the physiological sign parameters of the human body collected by at least one sensor, and converts the raw data from the analog signal to the digital signal. The signal processing module 712 of the first functional system 710 analyzes the digital signal and generates the processing result data according to the analysis result. The processing result data can be transmitted to the display processing module 713 of the first functional system 710 and the display processing module 723 of (one or more) second functional systems 720 simultaneously or in time-sharing through the transmission link. Among them, the display processing module 713 of the first functional system 710 converts the processing result data into a first display signal, and the first display signal is transmitted to the display connected to the display interface 714 of the first functional system 710, so that the display connected to the display interface 714 of the first functional system 710 displays the information corresponding to the first display signal. The display processing module 723 of the second functional system 720 converts the processing result data into a second display signal, and the second display signal is transmitted to the display connected to the display interface 724 of the second functional system 720, so that the display connected to the display interface 724 of the second functional system 720 displays the information corresponding to the second display signal.

[0074] The processing result data transmitted to the display processing module 713 of the first functional system 710 and the processing result data transmitted to the display processing module 723 of the second functional system 720 may be the same or different, depending on the application requirements. For example, if a customer needs to view information at a location relatively far from the display connected to the display interface 714, and therefore needs to use the display connected to the display interface 724 of the second functional system 720, then the processing result data transmitted to the display processing module 713 of the first functional system 710 and the processing result data transmitted to the display processing module 723 of the second functional system 720 may be the same, so that the user can view the information output by the monitoring function system on a display located at another location. For another example, the amount of information to be displayed is large, and the display connected to the display interface 714 of the first functional system 710 is insufficient to display all the information. At this time, the processing result data transmitted to the display processing module 713 of the first functional system 710 and the processing result data transmitted to the display processing module 723 of the second functional system 720 may be different, so that the user can view different information on the display connected to the display interface 714 of the first functional system 710 and the display connected to the display interface 724 of the second functional system 720.

[0075] In order to distinguish each other, the data processed by the display processing module 713 of the first functional system 710 can be referred to as the first data in the processing result data, and the first data is the whole data or part of the processing result data output by the signal processing module 712 of the first functional system 710; the data processed by the display processing module 723 of the second functional system 720 is referred to as the second data in the processing result data output by the signal processing module 712 of the first functional system 710, and the second data is the same as or different from the first data. That is, the display processing module 713 of the first functional system 710 further generates a first display signal according to the first data in the processing result data, and the first data is the whole data or part of the processing result data; the display processing module 723 of the second functional system 720 generates a second display signal according to the second data in the processing result data generated by the first functional system 710, and the second data is the same as or different from the first data.

[0076] Similarly, if there is more than one second function system 720 , the processing result data transmitted to different second function systems 720 may be the same or different, depending on application requirements.

[0077] In addition, the transmission of the processing result data can be through only one bus, that is, each second functional system 720 is connected to the same bus. Alternatively, the transmission of the processing result data can also be point-to-point transmission, that is, each second functional system 720 can use an independent transmission channel. Alternatively, the transmission of the processing result data can also be a combination of the above two forms. Wherein, the type of transmission channel can include but is not limited to Ethernet, controller area network (Controller Area Network, referred to as CAN), Universal Asynchronous Receiver / Transmitter (Universal Asynchronous Receiver / Transmitter, referred to as UART), RS232, RS422, RS485, Serial Peripheral Interface (Serial Peripheral Interface, referred to as SPI), Universal Serial Bus (Universal Serial Bus, referred to as USB), PCIe and other wired bus forms. It can also be WiFi, Bluetooth (Bluetooth, referred to as BT), Zigbee and other wireless forms.

[0078] In addition, when converting the processing result data into a display signal, the first functional system 710 may convert the processing result data into a first display signal based on a first display application requirement, and the second functional system 720 may convert the processing result data into a second display signal based on a second display application requirement, wherein the first display application requirement and the second display application requirement may be the same or different. That is, the first functional system 710 and the second functional system 720 may generate display signals according to their respective display application requirements (e.g., display layout, etc.) to be applied to different scenarios and meet different needs of users.

[0079] Overall, in Figure 8 In the example shown, the second functional system 720 only needs to have the same display processing module as the first functional system 710, and can realize the extended display of the monitor at a relatively low cost.

[0080] Fig. 9 Shows Figure 7 The first functional system 710 in the medical device 700 shown in the figure is an example of sending the data before the processing result data, that is, the digital signal obtained after the analog-to-digital conversion of the original data, to the second functional system 720. Fig. 9As shown, the signal conversion module 711 of the first functional system 710 receives the raw data representing the physiological sign parameters of the human body collected by at least one sensor, and converts the raw data from analog signals to digital signals. The digital signal can be transmitted to the signal processing module 712 of the first functional system 710 and the signal processing module 722 of (one or more) second functional systems 720 simultaneously or in time-sharing through the transmission link. Among them, the signal processing module 712 of the first functional system 710 analyzes the digital signal, generates processing result data according to the analysis result, and transmits the processing result data to the display processing module 713 of the first functional system 710, and the display processing module 713 of the first functional system 710 converts the processing result data into a first display signal, and the first display signal is transmitted to the display connected to the display interface 714 of the first functional system 710, so that the display connected to the display interface 714 of the first functional system 710 displays the information corresponding to the first display signal. The signal processing module 722 of the second functional system 720 analyzes the digital signal, generates processing result data according to the analysis result, and transmits the processing result data to the display processing module 723 of the second functional system 720. The display processing module 723 of the second functional system 720 converts the processing result data into a second display signal, and the second display signal is transmitted to the display connected to the display interface 724 of the second functional system 720, so that the display connected to the display interface 724 of the second functional system 720 displays the information corresponding to the second display signal.

[0081] Among them, the digital signal transmitted to the signal processing module 712 of the first functional system 710 and the digital signal transmitted to the signal processing module 722 of the second functional system 720 can be the same or different, depending on the application requirements. For example, the customer needs to view information at a relatively far distance from the display connected to the display interface 714, and therefore needs to use the display connected to the display interface 724 of the second functional system 720 located at another location. At this time, the digital signal transmitted to the signal processing module 712 of the first functional system 710 and the digital signal transmitted to the signal processing module 722 of the second functional system 720 can be the same, and then the processing result data generated by the display processing modules of the two are the same, which is convenient for the user to view the information output by the monitoring function system on the display located at another location. For another example, the amount of information to be displayed is large, and the display connected to the display interface 714 of the first functional system 710 is not sufficient to display all the information. At this time, the digital signal transmitted to the signal processing module 712 of the first functional system 710 and the digital signal transmitted to the signal processing module 722 of the second functional system 720 may be different. Afterwards, the processing result data generated by the display processing modules of the two are different, so that the user can view different information on the display connected to the display interface 714 of the first functional system 710 and the display connected to the display interface 724 of the second functional system 720.

[0082] In order to distinguish each other, the signal processed by the signal processing module 712 of the first functional system 710 can be referred to as the first digital signal in the digital signal, and the first digital signal is the whole signal or part of the digital signal output by the signal conversion module; the signal processed by the signal processing module 722 of the second functional system 720 is referred to as the second digital signal in the digital signal output by the signal conversion module 711 of the first functional system 710, and the second digital signal is the same as or different from the first digital signal. That is, the signal processing module 712 of the first functional system 710 further analyzes the first digital signal in the digital signal, generates the first processing result data according to the analysis result, and the first digital signal is the whole signal or part of the digital signal; the display processing module 713 of the first functional system 710 further generates the first display signal according to the first processing result data; the signal processing module 722 of the second functional system 720 analyzes the second digital signal in the digital signal transmitted by the first functional system 710, generates the second processing result data, and the display processing module 723 of the second functional system 720 generates the second display signal according to the second processing result data, and the second digital signal is the same as or different from the first digital signal.

[0083] Similarly, if there is more than one second functional system 720 , the digital signals transmitted to different second functional systems 720 may be the same or different, depending on application requirements.

[0084] In addition, the transmission of digital signals can be through only one bus, that is, each second functional system 720 is connected to the same bus. Alternatively, the transmission of digital signals can also be point-to-point transmission, that is, each second functional system 720 can use an independent transmission channel. Alternatively, the transmission of digital signals can also be a combination of the above two forms.

It can also be WiFi, Bluetooth (Bluetooth, referred to as BT), Zigbee and other wireless forms.

[0085] In addition, when converting the processing result data into a display signal, the first functional system 710 may convert the processing result data into a first display signal based on a first display application requirement, and the second functional system 720 may convert the processing result data into a second display signal based on a second display application requirement, wherein the first display application requirement and the second display application requirement may be the same or different. That is, the first functional system 710 and the second functional system 720 may generate display signals according to their respective display application requirements (e.g., display layout, etc.) to be applied to different scenarios and meet different needs of users.

[0086] Overall, in Fig. 9 In the example shown, the second functional system 720 only needs to have the same display processing module and signal processing module as the first functional system 710, and can realize the extended display of the monitor at a relatively low cost.

[0087] Fig.10 Shows Figure 7 The illustrated medical device 700 is another example in which the first functional system 710 sends data before the processing result data, that is, a digital signal obtained after analog-to-digital conversion of raw data, to the second functional system 720 . Fig.10 and Fig. 9 The examples shown are generally similar, and for the sake of brevity, their similarities will not be described here, only their differences will be described. Their differences are that Fig. 9 In the example shown, the signal processing module 722 of the second functional system 720 obtains the digital signal from the signal conversion module 711 of the first functional system 710; in contrast, Fig.10 In the example shown, the signal processing module 722 of the second functional system 720 obtains the digital signal from the signal processing module 712 of the first functional system 710. Therefore, generally, Fig. 9 In the example shown, the signal processing module 722 and the signal processing module 712 both obtain digital signals from the signal conversion module 711. Therefore, the digital signals obtained by the signal processing modules 712 and 722 of the first functional system 710 and the second functional system 720 respectively may be the same. Of course, the signal conversion module 711 of the first functional system 710 may also be allocated different digital signals to them in advance. Fig.10In the example shown, the signal output by the signal conversion module 711 is sent to the signal processing module 712, and the signal processing module 712 then transmits the signal to the signal processing module 722. Therefore, the digital signals processed by the signal processing modules 712 and 722 of the first functional system 710 and the second functional system 720 may be different, because the signal processing module 712 of the first functional system 710 may distribute a part of the digital signal obtained from the signal conversion module to the signal processing module 722 of the second functional system 720. Of course, the signal processing module 712 of the first functional system 710 may also only play a forwarding role, transmitting all the digital signals obtained from the signal conversion module to the signal processing module 722 of the second functional system 720. In this case, the digital signals processed by the signal processing modules 712 and 722 of the first functional system 710 and the second functional system 720 are the same.

[0088] Overall, in Fig.10 In the example shown, the second functional system 720 only needs to have the same display processing module and signal processing module as the first functional system 710, and can realize the extended display of the monitor at a relatively low cost.

[0089] Fig.11 Shows Figure 7 Another example of the first functional system 710 sending the processing result data to the second functional system 720 in the medical device 700 is shown. Fig.11 As shown, the signal conversion module 711 of the first functional system 710 receives the raw data representing the physiological sign parameters of the human body collected by at least one sensor, and converts the raw data from analog signals to digital signals. The signal processing module 712 of the first functional system 710 analyzes the digital signal and generates processing result data according to the analysis result. The processing result data can be transmitted to the display processing module 713 of the first functional system 710 and the signal processing module 722 of (one or more) second functional systems 720 simultaneously or in time-sharing through the transmission link. Among them, the display processing module 713 of the first functional system 710 converts the processing result data into a first display signal, and the first display signal is transmitted to the display connected to the display interface 714 of the first functional system 710, so that the display connected to the display interface 714 of the first functional system 710 displays the information corresponding to the first display signal. The signal processing module 722 of the second functional system 720 further processes the processing result data to obtain processed processing result data, and the display processing module 723 of the second functional system 720 converts the processed processing result data into a second display signal, and the second display signal is transmitted to the display connected to the display interface 724 of the second functional system 720, so that the display connected to the display interface 724 of the second functional system 720 displays the information corresponding to the second display signal.

[0090] Here, the processing of the processing result data by the signal processing module 722 of the second functional system 720 may be simply forwarding, for example, forwarding the processing result data to the display processing module 723 of the second functional system 720; or, the processing of the processing result data by the signal processing module 722 of the second functional system 720 may be filtering processing, which can generally be applied to a scenario including multiple second functional systems 720. For example, assuming that there are two second functional systems 720, the signal processing module 722 of each second functional system 720 obtains the same processing result data from the signal processing module 712 of the first functional system 710, but the signal processing module 722(a) of the first second functional system 720(A) filters out part of the data from the processing result data to obtain part of the data to be displayed, and the part of the data is processed into a display signal by its display processing module 723(a) and then displayed on the display connected to its display interface 724(a). The signal processing module 722(b) of the second second functional system 720(B) filters out part of the data from the processing result data to obtain part of the data to be displayed. The part of the data is processed into a display signal by its display processing module 723(b) and then displayed on the display connected to its display interface 724(b).

[0091] The processing result data transmitted to the display processing module 713 of the first functional system 710 and the processing result data transmitted to the signal processing module 722 of the second functional system 720 may be the same or different, depending on the application requirements. For example, if a customer needs to view information at a relatively far distance from the display connected to the display interface 714, and therefore needs to use a display connected to the display interface 724 of the second functional system 720 located at another location, the processing result data transmitted to the display processing module 713 of the first functional system 710 and the processing result data transmitted to the signal processing module 722 of the second functional system 720 may be the same, so that the user can view the information output by the monitoring function system on a display located at another location. For another example, the amount of information to be displayed is large, and the display connected to the display interface 714 of the first functional system 710 is insufficient to display all the information. At this time, the processing result data transmitted to the display processing module 713 of the first functional system 710 and the processing result data transmitted to the signal processing module 722 of the second functional system 720 may be different, so that the user can view different information on the display connected to the display interface 714 of the first functional system 710 and the display connected to the display interface 724 of the second functional system 720.

[0092] In order to distinguish each other, the data processed by the display processing module 713 of the first functional system 710 can be referred to as the first data in the processing result data, and the first data is the whole data or part of the processing result data output by the signal processing module 712 of the first functional system 710; the data processed by the signal processing module 722 of the second functional system 720 is referred to as the second data in the processing result data output by the signal processing module 712 of the first functional system 710, and the second data is the same as or different from the first data. That is, the display processing module 713 of the first functional system 710 further generates a first display signal according to the first data in the processing result data, and the first data is the whole data or part of the processing result data; the signal processing module 722 of the second functional system 720 obtains the second data in the processing result data from the signal processing module 712 of the first functional system 710, and generates the third processing result data according to the second data, and the display processing module 723 of the second functional system 720 is used to generate a second display signal according to the third processing result data, and the second data is the same as or different from the first data.

[0093] Similarly, if there is more than one second function system 720 , the processing result data transmitted to different second function systems 720 may be the same or different, depending on application requirements.

[0094] In addition, the transmission of the processing result data can be through only one bus, that is, each second functional system 720 is connected to the same bus. Alternatively, the transmission of the processing result data can also be point-to-point transmission, that is, each second functional system 720 can use an independent transmission channel. Alternatively, the transmission of the processing result data can also be a combination of the above two forms. Wherein, the type of transmission channel can include but is not limited to Ethernet, controller area network (Controller Area Network, referred to as CAN), Universal Asynchronous Receiver / Transmitter (Universal Asynchronous Receiver / Transmitter, referred to as UART), RS232, RS422, RS485, Serial Peripheral Interface (Serial Peripheral Interface, referred to as SPI), Universal Serial Bus (Universal Serial Bus, referred to as USB), PCIe and other wired bus forms. It can also be WiFi, Bluetooth (Bluetooth, referred to as BT), Zigbee and other wireless forms.

[0095] In addition, when converting the processing result data into a display signal, the first functional system 710 may convert the processing result data into a first display signal based on a first display application requirement, and the second functional system 720 may convert the processing result data into a second display signal based on a second display application requirement, wherein the first display application requirement and the second display application requirement may be the same or different. That is, the first functional system 710 and the second functional system 720 may generate display signals according to their respective display application requirements (e.g., display layout, etc.) to be applied to different scenarios and meet different needs of users.

[0096] Overall, in Fig.11 In the example shown, the second functional system 720 only needs to have the same display processing module and signal processing module as the first functional system 710, and can realize the extended display of the monitor at a relatively low cost.

[0097] The above exemplifies the medical device according to the embodiment of the present application. Based on the above description, the medical device according to the embodiment of the present application can realize its own extended display without changing its own existing software and hardware design, without replacing the processor and investing more resources in redevelopment, and can realize its own extended display by reusing its own existing software and hardware design, which has strong versatility, unlimited scalability and low cost advantages.

[0100] In step S1220, the processing result data or digital signal is transmitted to the second functional system, so that the second functional system directly obtains the processing result data or generates the processing result data based on the digital signal, and then converts the processing result data into a second display signal through the second functional system, and displays the information corresponding to the second display signal on the display connected to the second functional system, wherein the second functional system is a functional system formed after the monitoring functional system removes the function of processing raw data.
