[0051] Embodiments of the present invention

[0052] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0053] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art.

[0054] The serial numbers assigned to components or objects in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0055] At present, there are usually blind spots in the wireless network of hospitals. The network signal in these blind spots is poor or there is some interference. When patients carrying mobile medical devices and wearable medical devices move to these areas, the network connection between these medical devices and the central monitoring station may be disconnected. At this time, doctors cannot observe the patient's physical condition in real time through the central monitoring station, which poses a certain threat to the patient's life safety. Therefore, it is necessary to accurately locate the blind spots in the hospital wireless network through certain technical means, so as to optimize and avoid medical accidents, which has become one of the problems that hospitals urgently need to solve.

[0056] The status of a wireless network can be analyzed by analyzing the maximum response time, minimum response time, network device availability and other parameters from the host where the network analysis tool is located to a certain network device to form a network report. However, this working method has the following disadvantages: 1) The network report formed by this test method is only an overview report of the overall operation of the entire wireless network, and cannot accurately locate network problems; 2) This test method cannot accurately locate the location of the blind spot area of ​​the wireless network.

[0057] Based on this, the solution of the present application is proposed. In the embodiment of the present application, the wireless medical device and the central monitoring station access the wireless network through the wireless access point and communicate through the wireless network; the wireless medical device collects and processes at least one physiological parameter signal of the patient to obtain the physiological data of the patient, and also monitors the network status information of the wireless access point where it is located to obtain the first network status information; the wireless medical device sends the obtained physiological data and the first network status information to the central monitoring station through the wireless network; the central monitoring station at least displays the physiological data and stores the first network status information.

[0058] See also Figure 1 , a structural schematic diagram of a monitor is provided, the monitor may have an independent shell, the shell panel may have a sensor interface area, wherein the sensor interface area may integrate multiple sensor interfaces for connecting with external physiological parameter sensor accessories 111, and the shell panel may also include a small LCD (interactive design) display area, a display 119, an input interface circuit 122 and an alarm circuit 120 (such as an LED alarm area), etc. The parameter processing module has an external communication and power supply interface 116 for communicating with the host and taking power from the host. The parameter processing module may also support an external parameter module, and a plug-in monitor host may be formed by inserting the parameter module, as a part of the monitor, or it may be connected to the host through a cable, and the external parameter module is an external accessory of the monitor.

[0059] The internal circuit of the parameter processing module is placed in the housing, such as Figure 1As shown, it includes a parameter measurement circuit 112, a front-end signal processor 113 and a main processor 115. The parameter measurement circuit 112 at least includes at least one parameter measurement circuit among an electrocardiogram signal parameter measurement circuit, a respiratory parameter measurement circuit, a body temperature parameter measurement circuit, a blood oxygen parameter measurement circuit, a non-invasive blood pressure parameter measurement circuit, an invasive blood pressure parameter measurement circuit, etc. Each parameter measurement circuit is connected to an externally inserted sensor accessory 111 through a corresponding sensor interface. The output end of the parameter measurement circuit 112 is coupled to the front-end signal processor 113, and the communication port of the front-end signal processor 113 is coupled to the main processor 115. The main processor 115 is electrically connected to an external communication and power supply interface 116. The sensor accessory 111 includes detection accessories corresponding to the detection of physiological parameters such as electrocardiogram respiration, blood oxygen, blood pressure, and body temperature. The parameter measurement circuit 112 is mainly used to connect the sensor accessory 111 to obtain the collected physiological parameter signal. The sensor attachment 111 and parameter measurement circuit 112 corresponding to various physiological parameters can adopt the general circuits in the prior art. The front-end signal processor 113 completes the sampling and analog-to-digital conversion of the output signal of the parameter measurement circuit 112, and outputs a control signal to control the measurement process of the physiological signal. These parameters include but are not limited to: electrocardiogram, respiration, body temperature, blood oxygen, non-invasive blood pressure and invasive blood pressure parameters. The front-end signal processor 113 can be implemented by a single-chip microcomputer or other semiconductor devices, for example, the LPC2136 of PHLIPS or the mixed signal single-chip microcomputer such as ADuC7021 of ADI can be selected, and it can also be implemented by ASIC or FPGA. The front-end signal processor 113 can be powered by an isolated power supply, and the sampled data is simply processed and packaged, and then sent to the main processor 115 through the isolated communication interface. For example, the front-end signal processor 113 can be coupled to the main processor 115 through the isolated power supply and the communication interface 114. The reason why the front-end signal processor 113 is powered by an isolated power supply is that the DC / DC power supply isolated by a transformer plays the role of isolating the patient from the power supply equipment. The main purposes are: (1) to isolate the patient, and to float the application part to the ground through the isolation transformer, so that the patient leakage current is small enough; (2) to prevent the voltage or energy during the application of defibrillation or electric knife from affecting the boards and devices of the intermediate circuit such as the main control board (guaranteed by creepage distance and electrical clearance). Of course, the front-end signal processor 113 can also be connected to the main processor 115 through the cable 124.The main processor 115 is used to complete the calculation of physiological parameters and send the calculation results and waveforms of the parameters to a host (such as a host with a display, a PC, a central monitoring station, etc.) through the external communication and power interface 116; the main processor 115 can be connected to the external communication and power interface 116 through a cable 125 for communication and / or power supply; the parameter processing module can also include a power supply and battery management circuit 117, which draws power from the host through the external communication and power interface 116 and supplies it to the main processor 115 after processing, such as rectification and filtering; the power supply and battery management circuit 117 can also monitor, manage and protect the power obtained from the host through the external communication and power interface 116. The external communication and power interface 116 can be one or a combination of the local area network interfaces composed of Ethernet, Token Ring, Token Bus, and the fiber distributed data interface (FDDI) as the backbone network of these three networks, or one or a combination of wireless interfaces such as infrared, Bluetooth, wifi, WMTS communication, or one or a combination of wired data connection interfaces such as RS232 and USB. The external communication and power interface 116 can also be a combination of one or two of a wireless data transmission interface and a wired data transmission interface. The host can be any computer device such as the host of a monitor, an electrocardiograph, an ultrasonic diagnostic instrument, a computer, etc., and a monitor can be formed by installing the matching software. The host can also be a communication device, such as a mobile phone. The parameter processing module sends data to a mobile phone that supports Bluetooth communication through a Bluetooth interface to realize remote transmission of data. After the main processor 115 completes the calculation of the physiological parameters, it can also determine whether the physiological parameters are abnormal. If abnormal, an alarm can be issued through the alarm circuit 120. The memory 118 can store the intermediate and final data of the monitor, and store program instructions or codes for execution by the main processor 115, etc. If the monitor has the function of measuring blood pressure, it can also include a pump valve driving circuit 121, which is used to perform inflation or deflation operations under the control of the main processor 115.

[0060] like Figure 2 As shown, a hospital monitor networking system is provided, which can save the monitor data as a whole, centrally manage patient information and nursing information, and store the two in association, so as to facilitate the storage of historical data and associated alarms. Figure 2In the system shown, a bedside monitor 212 can be provided for each bed, and the bedside monitor 212 can be the aforementioned multi-parameter monitor or plug-in monitor. In addition, each bedside monitor 212 can also be paired with a portable monitoring device 213 for transmission. The portable monitoring device 213 provides a simple and portable parameter processing module, which can be worn on the patient's body to perform mobile monitoring of the patient. After the portable monitoring device 213 and the bedside monitor 212 perform wired or wireless communication, the physiological data generated by the mobile monitoring can be transmitted to the bedside monitor 212 for display, or transmitted to the central monitoring station 211 through the bedside monitor 212 for viewing by doctors or nurses, or transmitted to the data server 215 through the bedside monitor 212 for storage. In addition, the portable monitoring device 213 can also directly transmit the physiological data generated by the mobile monitoring to the central monitoring station 211 for storage and display through the wireless network node 214 set up in the hospital, or transmit the physiological data generated by the mobile monitoring to the data server 215 for storage through the wireless network node 214 set up in the hospital. It can be seen that the data corresponding to the physiological parameters displayed on the bedside monitor 212 may be derived from a sensor accessory directly connected to the monitor, or from the portable monitoring device 213, or from a data server.

[0061] Each of the aforementioned units or modules for executing the various steps can be stored in one or more of the aforementioned memories, and the above embodiments are respectively used to implement the aforementioned monitor or monitoring system, wherein each functional module includes an instruction set for executing each corresponding step in the above method, and the above modules or programs (i.e., instruction sets) do not need to be separate software programs, processes or modules. Therefore, in various embodiments, the various sub-blocks of these modules can be combined or rearranged. Therefore, in some embodiments of the present invention, the memory can store a subset of the modules or data structures described above.

[0062] See also Figure 3 , is a structural diagram of a wireless medical monitoring system provided in an embodiment of the present application, the wireless medical monitoring system includes at least one wireless medical device 01, a wireless access point 02, a wireless control unit 03 and a central monitoring station 04.

[0063] Among them, the wireless access point 02 is used to provide a wireless connection hotspot, the wireless control unit 03 and the wireless access point 02 form a wireless network for controlling the wireless access point 02; the wireless medical device 01 and the central monitoring station 04 access the wireless network through the wireless access point 02, the wireless medical device 01 and the central monitoring station 04 communicate through the wireless network, and the wireless medical device 01 can be managed and monitored by the central monitoring station 04.

[0064] The wireless medical device 01 is used to collect at least one physiological parameter signal of the patient, such as electrocardiogram, respiration, body temperature, blood oxygen, non-invasive blood pressure and invasive blood pressure, and process the collected physiological parameter signal to obtain the patient's physiological data; the wireless medical device 01 simultaneously monitors the network status information of the wireless access point 02 where it is located to obtain the first network status information; the wireless medical device 01 sends the physiological data and the first network status information obtained by the wireless medical device 01 to the central monitoring station 04 through the wireless network. The central monitoring station 04 is at least used to display the physiological data and store the first network status information monitored by the wireless medical device 01.

[0065] Among them, the first network status information may include one or more of SSID (Service Set Identifier), BSSID (Basic Service Set Identifier), name, location, channel, channel utilization, RSSI (Received Signal Strength Indication) value.

[0066] In this way, the wireless medical device 01 can not only execute the monitoring process of the patient's physiological parameters, but also execute the wireless network monitoring process at the same time, monitor the network status information of the wireless access point 02 where it is located, and use the same wireless network to send the patient's physiological data and the monitored first network status information to the central monitoring station 04. The patient's physiological parameter monitoring process and the network monitoring process share the same wireless network, realizing real-time monitoring of the network status information of the wireless network. The central monitoring station 04 can store the first network status information monitored by the wireless medical device 01, so as to further analyze the first network status information and form a network analysis report.

[0067] In actual applications, the wireless access point 02 and the wireless control unit 03 may be two different devices, or may be a dedicated device having both wireless access point functions and wireless control functions.

[0068] In one embodiment, after the central monitoring station 04 obtains the first network status information monitored by the wireless medical device 01, it is also used to analyze the first network status information to obtain a wireless network analysis result. In one embodiment, the first network status information can be saved in a network log file. For example, in one embodiment, the wireless medical device 01 can periodically send the first network status information to the central monitoring station 04 via the wireless network, and the central monitoring station 04 will detect whether the value of the first network status information has changed. If at least one of the information in the first network status information has changed, the currently received first network status information will be recorded in the network log file. In another embodiment, after receiving the first network status information sent by the wireless medical device 01, the central monitoring station 04 can record the first network status information in the network log file regardless of whether the first network status information has changed.

[0069] In one embodiment, when the central monitoring station 04 determines that there is a network log file in the analysis directory, it can analyze the data in the network log file to obtain a network event, and then analyze the network event according to a preset rule to obtain a wireless network analysis result. The network event at least includes the online and offline events of the wireless medical device, and the wireless network analysis result at least reflects the offline situation of the wireless network.

[0070] Specifically, the central monitoring station 04 may set at least one analysis directory, which may be used to store and manage network log files. The central monitoring station 04 may display a wireless network analysis interface, which includes a second menu for selecting an analysis directory, detect the user's operation in the wireless network analysis interface, and determine the analysis directory according to the user's operation on the second menu on the wireless network analysis interface. For example, a display effect of the wireless network analysis interface can be seen in Figure 4 , the user can click the folder icon in the "Analysis Directory" menu to find the storage path of the analysis directory and select the analysis directory from it. Specifically, when it is necessary to execute the wireless network analysis function, the user can start the wireless network analysis tool through the central monitoring station 04. At this time, the central monitoring station 04 can display the wireless network analysis interface on its display interface. The user can select the analysis directory where the network log file is located through the second menu in the wireless network analysis interface. After confirmation, the central monitoring station 04 determines whether there is a network log file in the selected analysis directory. If so, the data in the network log file in the selected analysis directory is analyzed to obtain network events, and then the network events are analyzed according to preset rules to obtain wireless network analysis results.

[0071] When analyzing network events according to preset rules, the central monitoring station 04 is specifically used to: based on network events within a set network analysis time, count the offline situations of the wireless medical devices 01 that meet the set conditions.

[0072] The set network analysis duration may be, for example, one day, two days, one week, two weeks, or other time periods. The central monitoring station 04 may count the disconnection status of the wireless medical device 01 based on network events within the set time period. In one embodiment, the network analysis duration may be set by the user in the wireless network analysis interface. Specifically, the central monitoring station 04 may display a wireless network analysis interface on its display interface. The wireless network analysis interface includes a first menu for setting the network analysis duration. The central monitoring station 04 detects the user's operation in the wireless network analysis interface and determines the network analysis duration based on the user's setting operation on the first menu on the wireless network analysis interface. For example, in a case such as Figure 4 In the wireless network analysis interface shown, the user can set the network analysis duration in the "Network Analysis Duration" menu. The user can directly enter the network analysis duration, or select the network analysis duration through the drop-down menu. For example, the network analysis duration is set to "one day". The central monitoring station 04 analyzes the data in the network log file in the selected analysis directory, and after obtaining the network events, it can count the offline situations of the wireless medical device 01 that meet the set conditions from the network events in the most recent day.

[0073] The counting of the offline situations of the wireless medical device 01 that meet the set conditions may include at least one of the following: (1) counting the total offline time of the wireless medical device 01 every day; (2) for each day, for each set time range, counting each offline time within the set time range, wherein the set time range may be, for example, less than or equal to 15 seconds, greater than 15 seconds and less than 60 seconds, and / or greater than or equal to 60 seconds, then taking days as units, counting each offline time of the wireless medical device 01 that is less than or equal to 15 seconds in a day, counting each offline time of the wireless medical device 01 that is greater than 15 seconds and less than 60 seconds in a day, and counting each offline time of the wireless medical device 01 that is greater than 60 seconds in a day; (3) for each day, counting the total offline time of the wireless medical device 01; (4) For each day, count the number of times the wireless medical device 01 is offline within each set period. For example, in units of days, for each day, count the number of times the wireless medical device 01 is offline every hour, or the number of times it is offline every two hours, etc.; (4) For each day, count the number of times the wireless medical device 01 is offline when the channel utilization falls within the channel utilization threshold when it is offline. For example, in units of days, for each day, count the number of times the wireless medical device 01 is offline when the channel utilization is greater than 60% when it is offline, count the number of times the wireless medical device 01 is offline when the channel utilization is between 40% and 60% when it is offline, count the number of times the wireless medical device 01 is offline when the channel utilization is less than 40% when it is offline, etc.; (5) For each day, count the information of the wireless access point where the wireless medical device 01 is located each time it is offline.

[0074] In one embodiment, after the central monitoring station 04 obtains the wireless network analysis result, the wireless network analysis result may be recorded in a file so that the user can view and analyze the wireless network analysis result.

[0075] In one embodiment, after the central monitoring station 04 obtains the wireless network analysis result, it is also used to generate a graphical report based on the wireless network analysis result. In this way, even users who do not have network-related knowledge can understand the analysis results to further optimize the wireless network. Specifically, the graphical report may include at least one of the distribution graph of the internal and external thresholds of the offline duration of the wireless medical device 01, the distribution graph of the number of wireless access points where the wireless medical device is offline, the distribution graph of the time area where the wireless medical device is offline, the distribution graph of the channel utilization rate where the wireless medical device is offline, the distribution graph of the number of times the wireless medical device is offline, and the distribution graph of the number of times the wireless medical device is offline in 24 hours.

[0076] Specifically, for the distribution map inside and outside the offline duration threshold, the central monitoring station 04 can analyze the first network status information, obtain the offline situation of the wireless medical device 01, and determine whether each offline duration falls within the offline duration threshold, thereby counting the offline durations that fall within the offline duration threshold, and counting the offline durations that fall outside the offline duration threshold, and then obtain the distribution map inside and outside the offline duration threshold based on the statistical results. The distribution map inside and outside the offline duration threshold can be a distribution map of each day obtained by counting on a daily basis. For example, the central monitoring station 04 can analyze the network event according to the above situation (2) of counting the offline situations of the wireless medical device 01 that meet the set conditions, and obtain the offline durations of the wireless medical device 01 that are greater than 15s and less than 60s in one day, that is, count the offline durations that fall within the offline duration threshold (greater than 15s and less than 60s), and at the same time obtain the offline durations that are less than or equal to 15s and the offline durations that are greater than or equal to 60s, that is, count the offline durations that fall outside the offline duration threshold, and then obtain the distribution map of the offline duration inside and outside the offline duration threshold of the wireless medical device 01 on this day.

[0077] The central monitoring station 04 can analyze the first network status information, and collect information about the wireless access point where the wireless medical device 01 is located each time it is offline. For example, statistical analysis can be performed on a daily basis to obtain a distribution chart of the number of wireless access points where the wireless medical device 01 is offline. The user can see the offline status of each wireless access point through the distribution chart and analyze the failure of each wireless access point.

[0078] The central monitoring station 04 can analyze the first network status information and count the time when the wireless medical device 01 is disconnected each time, so as to obtain a regional distribution map of the offline time of the wireless medical device 01. The user can further analyze and determine the offline reason of the wireless medical device 01 according to the regional distribution map of the offline time.

[0079] The central monitoring station 04 can analyze the first network status information, and count the number of disconnections when the channel utilization of the wireless medical device 01 falls within the channel utilization threshold range when the wireless medical device 01 is disconnected, such as the number of disconnections when the channel utilization is greater than 60%, the number of disconnections when the channel utilization is between 40% and 60%, and the number of disconnections when the channel utilization is less than 40%, so as to obtain a distribution map of the channel utilization when the wireless medical device 01 is disconnected. The distribution map can be used to know the busy and idle status of the wireless network when the wireless medical device 01 is disconnected.

[0080] The central monitoring station 04 can analyze the first network status information and count the number of disconnections of the wireless medical device 01 in each set period, such as the number of disconnections every two hours, the number of disconnections every day, etc., so as to obtain a distribution diagram of the number of disconnections of the wireless medical device 01, and analyze the fault of the wireless medical device 01 based on the distribution diagram. A distribution diagram of the number of disconnections of the wireless medical device 01 in 24 hours can also be obtained, and the movement of the patient carrying the wireless medical device 01 can be analyzed based on the distribution diagram.

[0081] In one embodiment, after generating the graphical report, the central monitoring station 04 may also save the graphical report. The saving path of the graphical report may be pre-set or may be set by the user.

[0082] Specifically, the central monitoring station 04 may display a wireless network analysis interface on its display interface, and the wireless network analysis interface may include a save menu for saving a graphical report. The central monitoring station 04 detects the user's operation in the wireless network analysis interface, and saves the graphical report in the selected save path according to the user's operation on the save menu on the wireless network analysis interface. Figure 4 In the wireless network analysis interface shown, the user can set the save path of the graphical report in the "Analysis Report Save Path" menu. After setting, the user can click the "Save" button. At this time, the central monitoring station 04 will save the graphical report according to the set save path.

[0083] In one embodiment, Figure 4 As shown, the wireless network analysis interface may also include an "analysis" function key and / or a "version" function key. When the "analysis" function key is triggered, the central monitoring station 04 starts the function of analyzing the data in the network log file, and the user can manually start the wireless network analysis function provided by the present application. Of course, the central monitoring station 04 may also automatically start the wireless network analysis function. For example, the central monitoring station 04 may automatically perform wireless network analysis after receiving the first network status information. The user may learn about the version, copyright, and other information of the current network analysis tool (running on the central monitoring station 04, providing the wireless network analysis function of the present application) by triggering the "version" function key.

[0084] In one embodiment, the central monitoring station 04 can also implement an email function, and after generating a graphical report, the graphical report can be sent to the user via an email. For example, the central monitoring station 04 can provide the user with an email setting function, allowing the user to set an email address for receiving the report. After generating the graphical report, the central monitoring station 04 can send the graphical report to the user according to the email address, for example, the graphical report can be sent immediately after it is generated, or it can be sent periodically.

[0085] In one embodiment, the central monitoring station 04 can also collect network status information of the wireless access point 02 at a regular interval to obtain second network status information, and then the data in the network log file and the second network status information can be comprehensively analyzed to obtain wireless network analysis results. The second network status information may include one or more of MAC address (Media Access Control Address), BSSID, IP address (Internet Protocol Address), name, location, number, channel, channel utilization, and interference information.

[0086] Specifically, the central monitoring station 04 determines whether there is second network status information collected by the central monitoring station 04 in the analysis directory. If so, the second network status information is analyzed, and the mapping relationship between the BSSID and the name of the wireless access point 02 is obtained and cached. When it is determined that there is a network log file in the analysis directory, the data in the network log file is analyzed based on the mapping relationship; if the second network status information collected by the central monitoring station 04 does not exist in the analysis directory, when it is determined that there is a network log file in the analysis directory, the data in the network log file is analyzed.

[0087] Based on this, see Figure 5 , is a flow chart of a method for the central monitoring station 04 to comprehensively analyze the data in the network log file and the second network status information. The method may include the following steps:

[0088] Step 101: Determine whether second network status information exists in the analysis directory.

[0089] After the central monitoring station 04 starts the wireless network analysis function, it first determines whether the analysis directory contains the second network status information collected by the central monitoring station 04. If so, step 102 is executed, otherwise, step 103 is started.

[0090] Step 102: Analyze the second network status information.

[0091] When the central monitoring station 04 determines that there is second network status information in the analysis directory, it analyzes the second network status information, extracts the mapping relationship between the BSSID and the name of the wireless access point 02 from the second network status information and caches it. The BSSID is used to distinguish the network channel of the wireless network. For a wireless access point 02, it can correspond to multiple BSSIDs. One BSSID can connect to one wireless medical device 01, that is, one wireless access point 02 can connect to multiple wireless medical devices 01. By analyzing the second network status information and extracting the mapping relationship between the BSSID and the name of the wireless access point 02 from the second network status information, the name of the wireless access point 02 where the wireless medical device 01 is located can be accurately known.

[0092] Step 103: Determine whether there is a network log file in the analysis directory.

[0093] The central monitoring station 04 determines whether there is a network log file recorded by the central monitoring station 04 in the analysis directory, and the network log file is used to store the first network status information monitored by the wireless medical device 01. If it exists, step 104 is executed, otherwise step 109 is executed.

[0094] Step 104: Analyze the data in the network log file to obtain network events.

[0095] When the central monitoring station 04 determines that there is no second network status information in the analysis directory but there is a network log file, it analyzes the data in the network log file to obtain network events, which at least include online and offline events of the wireless medical device 01.

[0096] When the central monitoring station 04 determines that there is the second network status information in the analysis directory and there is a network log file, the mapping relationship between the BSSID and the name of the wireless access point 02 is integrated, and the data in the network log file is analyzed to obtain network events, which at least include the online and offline events of the wireless medical device 01. By extracting the mapping relationship between the BSSID and the name of the wireless access point 02 from the second network status information, the name of the wireless access point 02 where the wireless medical device 01 is located can be accurately known, so that the first network status information can be complemented. After analyzing the data in the network log file, the wireless access point 02 corresponding to the obtained network event can be accurately known, and the accurate mapping relationship between the network event and the wireless access point 02 can be obtained.

[0097] Step 105: Store the network event.

[0098] After obtaining the network event, the central monitoring station 04 may store the network event of each wireless medical device 01 in a file belonging to each wireless medical device 01 , so that the user can view and analyze the wireless network operation status of each wireless medical device 01 .

[0099] Step 106: Analyze the network event to obtain a wireless network analysis result.

[0100] After the central monitoring station 04 obtains the network event, it analyzes the network event according to the preset rules to obtain the wireless network analysis result, which at least reflects the disconnection of the wireless network. Alternatively, when receiving the instruction from the user to view and analyze the wireless network operation of the wireless medical device 01, the network event is read from the corresponding file storing the network event, and then the network event is analyzed according to the preset rules to obtain the wireless network analysis result. Specifically, based on the network events within the set network analysis time, the disconnection of the wireless medical device 01 that meets the set conditions can be counted.

[0101] After obtaining the wireless network analysis result, the central monitoring station 04 may execute the following steps 107 and 108 .

[0102] Step 107: Save the wireless network analysis result.

[0103] After obtaining the wireless network analysis result, the central monitoring station 04 may record the wireless network analysis result into a file and save it so that the user can view and analyze the wireless network analysis result.

[0104] Step 108: Generate a graphical report.

[0105] After the central monitoring station 04 obtains the wireless network analysis result, it can generate a graphical report based on the wireless network analysis result. The graphical report can include at least one of the distribution graph of the time length of the wireless medical device 01 being disconnected within and outside the threshold, the distribution graph of the number of wireless access points where the wireless medical device is disconnected, the distribution graph of the time area where the wireless medical device is disconnected, the distribution graph of the utilization rate of the channel where the wireless medical device is disconnected, the distribution graph of the number of times the wireless medical device is disconnected, and the distribution graph of the number of times the wireless medical device is disconnected within 24 hours. In this way, even users who do not have network-related knowledge can understand the analysis results, so as to further optimize the wireless network.

[0106] Step 109: End the analysis.

[0107] In the wireless medical monitoring system provided by the embodiment of the present application, the wireless medical device and the central monitoring station communicate via a wireless network. The wireless medical device can use the same wireless network to simultaneously execute the monitoring process of the patient's physiological parameters and the network monitoring process.

The central monitoring station can store the first network status information, and can also further analyze the first network status information to obtain a wireless network analysis result. Through the wireless network analysis result, at least the offline status of the wireless access point where the wireless medical device is located can be understood, so as to optimize the wireless network. The central monitoring station can also form a graphical report based on the obtained wireless network analysis results, so that users who do not have network-related knowledge can also understand the analysis results, so as to further optimize the wireless network. On the other hand, the central monitoring station can also provide users with a simple and friendly user interaction interface, such as Figure 4 The wireless network analysis interface shown is used by the user to manually start the wireless network analysis function, set the network analysis duration, select the analysis directory of the network log file, set the save path of the graphical report, etc.
