[0109] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0110] With the development of medical technology, medical sites provide more and more medical devices for patients, such as patient monitors, ventilators, anesthetizing machines, infusion pumps, and the like arranged in operating rooms or monitoring wards. However, the medical devices usually work independently, for example, data information is displayed, alarmed, or stored on the respective devices. Although some medical devices can send their own data information to a centralized monitoring system, such as a central monitoring station or a central infusion pump station, data communication between the medical devices still cannot be achieved.

[0111] However, more and more monitoring scenarios require data information intercommunication of the medical devices, which not only facilitates clinical staff to quickly obtain complete information of patients and reduces the workload of the medical staff, but also assists the medical staff to make faster and more accurate clinical decisions.

[0112] The current data information intercommunication scheme is that the medical devices establish a communication connection with the central monitoring system through a data communication device, and respectively send their own data information to the central monitoring system. For example, Figure 1 The provided example is that, taking a patient bed as a unit, a monitor, an infusion pump, an anesthetizing machine, and a ventilator are respectively connected to a local area network through a network switch to establish a communication connection with a hospital information system. The communication connection mode between each medical device and the network switch can be wireless, or when the medical device has no network port configuration, the medical device is connected to a special data acquisition terminal through a serial port or other wired mode to access the local area network.

[0113] The inventors find at least the following problems in implementing the above data communication method: 1. Different protocols can be used by various medical devices to communicate with the hospital information system, and the implementation of different medical devices is different, which is difficult to develop and has a long cycle; 2. The medical devices send their own collected data information, and all data information is not uniformly summarized, so that the complete condition of the patient cannot be reflected; 3. The data information sent by the medical devices has a time stamp, and the different clocks of different medical devices cause differences in the time stamp of the data information, which further affects the unified comprehensive analysis of the hospital information system on the data information sent by all medical devices; 4. The data information is sent to the remote hospital information system, and the bedside medical devices do not realize the comprehensive management of the patient information, and it is not easy to realize the mobile plug-and-play of some bedside medical devices.

[0114] To solve at least one of the above problems, the present application provides a patient monitoring system. In the system, one or more bedside medical devices are respectively in communication connection with a patient monitoring device, forming a bedside communication network with the patient monitoring device as the center. As Figure 2 Provided are examples, infusion pumps, anesthesia machines, ventilators, and telemetry monitors, which are respectively in communication connection with the patient monitoring device. It should be noted that the communication connection mode can include wired, wireless, or serial port, etc., and the present application does not make specific limitations.

[0115] The medical devices and the patient monitoring device can interact with data information, or the medical devices can also interact with data information through the patient monitoring device, so as to realize the intercommunication of bedside data information among various medical devices. Further, the patient monitoring device can also directly or indirectly send data information to a central information system, such as a central monitoring station, a clinical information system (CIS), a hospital information system (HIS), or an electronic medical record system (EMR), etc. As Figure 2 As shown, the patient monitoring device sends data information to the hospital information system through a network switch.

[0116] The following specific description, the patient monitoring device (also can be called patient monitor) and medical device between the various application scenarios of interacting with data information.

[0117] As Figure 3 The present application embodiment provides a communication method of a medical device, which comprises:

[0118] S301: The patient monitoring device displays information, obtains an operation instruction, and collects physiological data of a patient.

[0119] Specifically, the patient monitoring device is provided with a human-computer interaction device, which is used to display information and obtain operation instructions input by an operator of the device. For example, the human-computer interaction device can be a display screen with touch function, or can include a separate display device and a separate input device, or other device structures that can realize the function of human-computer interaction.

[0120] The information displayed by the patient monitoring device can include data information generated in the implementation of the embodiments of the present application and / or other data information related to patient monitoring. The operation instructions obtained by the patient monitoring device can include operation instructions required in the implementation of the embodiments of the present application and / or other operation instructions related to patient monitoring.

[0121] The patient monitoring device can also be provided with at least one physiological parameter sensor for collecting at least one physiological data of the patient associated therewith. The physiological data can be stored locally in the patient monitoring device or uploaded to a central information system. The specific form of the physiological parameter sensor is not limited in the embodiments of the present application.

[0122] It should be noted that the functions of information display, operation instruction acquisition and physiological data collection are basic functions of the patient monitoring device as a monitoring device, and the embodiments of the present application do not make specific limitations. The execution sequence of this step is also not limited thereto, and it can be executed in any step in the embodiments of the present application according to the actual monitoring process.

[0123] S302: The medical device performs a relevant medical operation on the patient.

[0124] Specifically, the medical device is also associated with the patient associated with the patient monitoring device, and the medical device is provided with a medical accessory for performing a relevant medical operation on the patient. It should be noted that different types of medical devices have different types of medical accessories and perform different medical operations. For example, the medical device is a ventilator, the medical accessory is a component for assisting the patient in breathing, and the medical accessory is used to ventilate the patient to assist the patient in breathing. For example, the medical device is an infusion pump, the medical accessory is a component related to infusion of drugs, and the medical accessory is used to infuse the required drugs for the patient. For example, the medical device is an anesthesia machine, the medical accessory is a component related to anesthesia, and the medical accessory is used to input anesthetic drugs to perform anesthesia operation on the patient. Of course, the medical device can also be other bedside medical related devices that can be expected by those skilled in the art, and the embodiments of the present application do not make specific limitations.

[0125] S303: The medical device sends a pairing connection request.

[0126] Specifically, the medical device is connected with the patient monitoring device in a wired, wireless network or serial port and the like. The medical device can actively or based on the user's trigger operation, generate and send a pairing connection request. For example, the medical device sends a pairing connection request after starting to request the patient monitoring device to pair and connect with it. The pairing connection request can be sent by broadcast, multicast, groupcast, unicast and the like.

[0127] The medical device can be one or multiple. Each medical device sends a respective pairing connection request. The pairing connection request can carry a device identifier of the medical device, which is used to uniquely represent the medical device. The device identifier can include the name, device code, type name and the like of the medical device.

[0128] S304: The patient monitoring device listens to the pairing connection request of the medical device and establishes a first communication link with the medical device.

[0129] Specifically, the patient monitoring device executes a pairing listening control program through the processor to listen to the pairing connection request sent by the medical device in real time. When the pairing connection request sent by the medical device is listened to, pairing with the medical device is determined.

[0130] The pairing connection request sent by the medical device can be generated in the following manner: the patient monitoring device sends online state information when receiving a trigger instruction, the online state information including the location information of the patient monitoring device, and if the location information of the patient monitoring device and the location information of the medical device satisfy a preset location condition, a pairing connection request can be sent to the patient monitoring device to request pairing with the patient monitoring device.

[0131] One example of the pairing process is that the patient monitoring device listens to the pairing connection request of the medical device and directly completes pairing with the medical device. Another example of the pairing process is that when the pairing connection request sent by the medical device is listened to, pairing with the medical device is determined based on the operation instruction input by the device operator to establish a first communication link. Specifically, the patient monitoring device listens to the pairing connection request of the medical device, and the man-machine interaction device provides a pairing setting interface, which includes the device identifier extracted from the pairing connection request. After the device operator inputs a confirmation instruction to a certain device identifier, the patient monitoring device completes pairing with the medical device corresponding to the device identifier.

[0132] One specific form of the pairing setting interface is as follows: Figure 6As shown, the pairing setting interface includes a device type floating window, which includes the types of devices that can be paired, such as infusion pumps (Pump), telemetry monitors (Telemetry), pluggable accessories (Mobile module), ventilators (Ventilator), and anesthesia machines (Anesthesia). When the patient monitoring device monitors a pairing connection request for a certain type of medical device, the type of medical device is highlighted. After the user manually confirms or the patient monitoring device automatically confirms the pairing connection request for the type of medical device, the pairing of the type of medical device is completed, and the relevant information of the medical device is added to the medical device interface at the bottom of the floating window.

[0133] It should be noted that, after monitoring a pairing connection request from a medical device, the patient monitoring device can generate a device list of medical devices based on the device identifier carried in the pairing connection request and control the human-computer interaction device to display the device list. By viewing the device list, the device operator can identify the medical device currently being requested to connect to the patient monitoring device.

[0134] In an embodiment of the present application, the medical device actively sends a pairing connection request, and the patient monitoring device performs pairing after monitoring the request. In another embodiment, the patient monitoring device can actively send a pairing connection request to the medical device. The following provides three possible pairing implementation methods.

[0135] like Figure 4 As shown, the first implementation method is that the patient monitoring device monitors the online status information sent by the medical device (step 3.1). The online status information includes location information. If the location information of the medical device and the location information of the patient monitoring device meet the preset location conditions, the patient monitoring device is paired with the medical device to establish a first communication link. Specifically, the online status information may include location information, such as bed number, ward number, department identification, etc. After the patient monitoring device receives the location information of the medical device, it determines whether its own location information and the location information of the medical device meet the preset location conditions (step 3.2). The location conditions are such as binding to the same bed number, binding to the same ward number, binding to the same department identification, etc. As long as the location conditions are met, it is paired with the medical device, for example, a pairing connection request is sent to the medical device (step 3.3) to request pairing with the medical device; after the medical device obtains the pairing connection request, it is paired with the patient monitoring device to establish a first communication link (step 3.4). This pairing method can automatically pair with the medical device whose location information meets the conditions. The pairing process is more automated, saving manual operations. Of course, the working process after the patient monitoring device is paired and connected with the medical device in step 3.4 is the same as Figure 3 Step 305 and subsequent steps are the same and will not be described in detail here.

[0136] As Figure 5 shown in FIG. 30, in a second embodiment, the medical device can send out online status information (step S3001) when receiving a trigger instruction, such as a power-on instruction, an online instruction input by the device operator, etc., the online status information being used to indicate that the medical device is in an online connectable state. After the patient monitoring device listens to the online status information of the medical device, it sends a pairing connection request to the corresponding medical device based on a pairing connection instruction (step S3002), and after determining to pair with the medical device, the first communication link is established (step S3003). Specifically, the online status information sent by the medical device at least includes the device identification of the medical device, and after the patient monitoring device listens to the online status information of the medical device, it controls the man-machine interaction device to display a device list of all online medical devices based on the device identification carried by the online status information. The device operator can select a medical device in the device list and input a pairing connection instruction to it. The patient monitoring device sends a pairing connection request to the medical device based on the pairing connection instruction, the pairing connection request being used to request pairing with the medical device, and when the medical device responds to the pairing connection request, pairing is achieved, thereby establishing the first communication link. Figure 5 The other steps in the embodiment are the same as in Figure 3 , and specific descriptions can be made by referring to the above description of Figure 3 .

[0137] In a third embodiment, the patient monitoring device controls the man-machine interaction device to display a pairing setting interface, the pairing setting interface including a device type to be connected, and after the device operator selects a target device type, the patient monitoring device sends a pairing connection request to the medical device of the target device type. Still taking the interface provided in Figure 6 as an example, the device operator can select a target device type in the device types included in the floating window. After the medical device of the target device type receives the pairing connection request, it automatically completes pairing with the patient monitoring device. Or the medical device of the target device type provides a pairing setting item (or pairing confirmation reminder information), and based on the confirmation of the device operator to the pairing connection request, the medical device completes pairing with the patient monitoring device.

[0138] After the patient monitoring device and the medical device establish the first communication link, the connection state of the medical device can be displayed through the man-machine interaction device of the patient monitoring device. For example, the patient monitoring device generates a bedside device management interface, an example of the device management interface being shown in FIG. 31. Figure 7 As shown in FIG. 31, the telemetry monitor is in a connected state, the infusion pump is in a disconnected but locked state (the lock-shaped icon indicating the locked state), and the ventilator is in an unconnected state.

[0139] It should be noted that the pairing process can also be understood as a process of establishing a communication link, and completing the pairing means successfully establishing a communication link between devices. In order to distinguish from other communication links, the communication link can be referred to as a first communication link. The communication link is used for transmission of data information between two devices, and the data information at least includes time information (clock information) of the patient monitoring device, patient information, and medical data carrying a time stamp, as described in the following steps.

[0140] It should be noted that the above-mentioned establishment method of the first communication link is only an example, and the patient monitoring device and the medical device can also establish the first communication link through other existing communication link establishment methods. That is, no matter through the existing method or the method provided by the embodiment of the application, as long as the first communication link is established between the patient monitoring device and the medical device, the data transmission such as time information synchronization, patient information synchronization, and time-stamped medical data transmission can be performed through the first communication link.

[0141] S305: The patient monitoring device synchronizes the time information to the medical device through the first communication link.

[0142] Specifically, in order to realize the clock unification between the medical device and the patient monitoring device, the patient monitoring device can synchronize its own time information to the medical device. The medical device paired with the patient monitoring device can be one or multiple. If the medical device is multiple, the time information of the patient monitoring device is synchronized to each medical device. The medical device can open the interface of the clock synchronization software, and the patient monitoring device can synchronize the time information through the interface. After the time information is synchronized between the devices, the time stamps of the medical data collected by each device for the same patient can be synchronized, and the medical data under the same time stamp can be accurately associated.

[0143] For example, the patient monitoring device periodically synchronizes its own time information to the medical device. The specific duration of the period can be set according to actual needs, and the embodiment of the application does not make specific limitation.

[0144] In an implementation, the patient monitoring device can establish a communication link (referred to as a second communication link for distinguishing from other communication links) with a clock server, acquire the standard time of the clock server through the second communication link, and take the standard time as the time information of the patient monitoring device to synchronize to the medical devices. Specifically, the patient monitoring device can synchronize the standard time of the clock server through the hospital data network at certain time intervals, such as every hour, and synchronize the standard time to the medical devices. Specifically, the patient monitoring device can synchronize the updated time information to the medical devices immediately after acquiring the standard time of the clock server, or can synchronize the updated time information to the medical devices when the synchronization period is reached.

[0145] One scheme of clock synchronization is shown in FIG. 1. A clock server can be set up, which can synchronize its standard time to the patient monitoring device and the central information system through a communication link, and the patient monitoring device can synchronize the standard time to the medical devices at the bedside, such as the ventilator, the infusion pump, the anesthetizing machine, etc., so as to ensure the unity of the clocks of the medical devices and the accuracy of the processing of data information. Figure 8

[0146] It should be noted that when the patient monitoring device synchronizes the time information to the medical devices, there is a certain time delay in the arrival of the time information of the patient monitoring device to the medical devices due to some reasons, such as the time required for the transmission of the time information, so that the clock of the medical devices is not completely consistent with the clock of the patient monitoring device, and further causes a certain error between the time stamp of the medical data collected by the medical devices and the time stamp of the medical data collected by the patient monitoring device at the same time. In order to further improve the consistency of the clock information, the patient monitoring device can determine the transmission time of the data between the patient monitoring device and the medical devices (i.e., the data time difference) in advance, and after the medical devices receive the synchronized time information, the medical devices first correct the time information according to the data time difference, and then synchronize the time of the medical devices to the corrected time information. Alternatively, the patient monitoring device can first correct the time information to be sent according to the data time difference before synchronizing the time information to the medical devices, and then send the corrected time information to the medical devices.

[0147] S306: The patient monitoring device synchronizes the patient information to the medical devices through the first communication link.

[0148] ​Specifically, the patient information synchronization between the patient monitoring device and the medical device can include that the patient monitoring device sends the patient information to the medical device for synchronization, or that the medical device sends the patient information to the patient monitoring device for synchronization. The specific synchronization mode can be determined automatically by the device or by the device operator. For example, the man-machine interaction device of the patient monitoring device can provide a patient information synchronization mode selection item, and based on the operation instruction input by the device operator, the patient monitoring device determines to synchronize the patient information in the patient monitoring device to the medical device or to synchronize the patient information in the medical device to the patient monitoring device.

[0149] The patient information is the basic information of the patient associated with the patient monitoring device and the medical device, including but not limited to name, gender, age, medical record, etc. The patient information is generally collected when the patient is admitted to the hospital and recorded in the patient information database in the central information system. The specific implementation mode of synchronizing the patient information between the patient monitoring device and the medical device can include the following modes.

[0150] One specific implementation mode is that the patient monitoring device establishes a communication link (for the sake of distinguishing from other communication links, this communication link is referred to as a third communication link) with the central information system, and obtains the patient information from the central information system through the third communication link, thereby synchronizing the patient information to the medical device. Specifically, the patient monitoring device can obtain the patient data from the central information system in two ways. As shown in Figure 9 the patient information database server (set in the central information system). Mode one is that the patient information database server can obtain the identification of the patient monitoring device associated with the patient, such as the bed number or the physical address, so as to actively push the patient information to the patient monitoring device according to the identification. Mode two is that the patient monitoring device includes an identification code scanning device, which obtains the patient identification by scanning the identification code of the patient such as the bracelet barcode, two-dimensional code, etc., so as to obtain more detailed patient information of the patient from the patient information database server according to the patient identification. Further, as shown in Figure 9 the patient monitoring device sends the patient information to the medical devices such as the ventilator, infusion pump, and anesthesia machine that are also associated with the patient at the bedside through the first communication link.

[0151] Another specific implementation mode is that the medical device obtains the patient information from the central information system and synchronizes the patient information to the patient monitoring device. The specific implementation mode is similar to the synchronization process of the patient monitoring device described above, which is not described here.

[0152] It should be noted that the step is not limited to be performed after the time information is synchronized, but can also be performed simultaneously or after the time information is synchronized. That is, as long as the first communication link is established, the synchronization of the patient information can be performed according to actual settings.

[0153] S307: The medical device generates a time stamp based on the time information and obtains medical data carrying the time stamp.

[0154] Specifically, after the medical device synchronizes the time information of the patient monitoring device, when the medical data of the patient is collected, the time stamp of the medical data can be generated based on the time information. The time stamp can represent the collection time point of the medical data. It should be noted that the medical data can be physiological data collected by the medical device itself or other medical data generated in the process of performing medical operations by the medical device. For example, the medical data can include but is not limited to real-time values of physiological parameters, physiological parameter waveforms, physiological alarm information, device setting information, device alarm information, and the like.

[0155] S308: The medical device sends the medical data carrying the time stamp to the patient monitoring device through the first communication link.

[0156] Specifically, the medical device can send the medical data with the time stamp to the patient monitoring device through the first communication link according to a preset sending period.

[0157] S309: The patient monitoring device performs a preset processing operation on the medical data carrying the time stamp.

[0158] Specifically, the patient monitoring device executes a data processing program through the processor to perform the processing operation on the medical data in a preset manner. The preset processing operation includes but is not limited to display, alarm, storage, forwarding, data association, and the like.

[0159] For example, the medical data with the time stamp can be stored locally in the patient monitoring device.

[0160] For another example, the medical data with the same time stamp sent by each medical device can be associated according to the time stamp of the medical data, and further, the medical data of the medical device can be associated with the medical data of the patient monitoring device with the same time stamp, such as the collected physiological data.

[0161] For another example, the medical data of the medical device can be further associated, stored and / or displayed with the associated medical data of the patient monitoring device.

[0162] For another example, the patient monitoring device can transmit the medical data to the central information system through the third communication link. Figure 8As shown, based on the synchronization-based time information, the medical devices such as ventilators, infusion pumps, and anesthetizers generate time stamps and send the medical data with the time stamps to the patient monitoring device, and the patient monitoring device forwards the collected medical data and / or its own medical data to the central information system, so that the time stamps of the medical data stored by the central information system are all generated based on the standard time of the clock server, thereby ensuring the consistency of the time stamps of the medical data. Further, the clock of the central information system is also synchronized with the standard time of the clock server, so if the central information system performs time-related processing on the collected medical data, the accuracy of the data processing can also be ensured.

[0163] It should be noted that the above several processing operations are exemplary and in actual application, other data processing operations expected by those skilled in the art can be performed on the medical data according to the medical care needs.

[0164] From the above technical solutions, it can be seen that the embodiments of the present application provide a communication method of a medical device, taking the patient monitoring device as the center, one or more medical devices at the bedside can establish a communication link with the patient monitoring device, and the clock synchronization of the medical device, the synchronization of the patient information, and the centralized and unified processing of the medical data of the patient are realized through the patient monitoring device. This method not only can reduce the difficulty of clock management, but also can realize the associated processing of the medical data collected by multiple different devices, thereby reducing the difficulty of patient information management.

[0165] In actual application, in addition to pairing with the patient monitoring device, the medical device can also disconnect the communication link, thereby simply and conveniently realizing the mobile plug-and-play of the medical device and improving the clinical use efficiency of the device. The present application provides the following several specific embodiments of disconnecting the communication link in combination with various different use scenarios.

[0166] Application scenario one: when the association between the patient monitoring device and the patient is released, the pairing relationship with the medical device is directly released.

[0167] As shown in the above Figure 10 , the patient monitoring device can establish a first communication link with the medical device by referring to the communication method of the medical device shown in the above Figures 3-5 . Through the first communication link, the patient monitoring device can synchronize time information to the medical device, and the patient monitoring device can synchronize patient information with the medical device, and the patient monitoring device can obtain medical data with time stamps from the medical device.

[0168] A patient monitoring device and a medical device are associated with a patient for performing medical functions on the patient. The patient monitoring device and / or the medical device need to be disassociated with the patient under certain conditions, such as the patient being discharged. The disassociation instruction can be received by any of the patient monitoring device and the medical device.

[0169] For example, the disassociation instruction can be sent by other devices to the patient monitoring device and / or the medical device. For example, a central information system determines that the patient is discharged according to the medical data of the patient, and sends the disassociation instruction to the patient monitoring device and / or the medical device associated with the patient. The medical device receives the disassociation instruction and sends it to the patient monitoring device.

[0170] For example, a device operator inputs the disassociation instruction to the patient monitoring device, or the device operator inputs the disassociation instruction to the medical device, and the medical device sends the disassociation instruction to the patient monitoring device.

[0171] As shown in Figure 10 Regardless of the way, the patient monitoring device determines the disassociation instruction and disconnects the first communication link between the patient monitoring device and the medical device, and disassociates with the medical device. Specifically, the patient monitoring device determines the disassociation instruction, which means that the patient monitoring device no longer needs to perform monitoring operations on the patient, and no longer needs to obtain medical data of the patient through the bedside medical device, so the patient monitoring device directly disconnects the first communication link between the patient monitoring device and the medical device, and disassociates with the medical device.

[0172] It should be noted that the communication link and the pairing relationship are not the same. Disconnecting the communication link means that the current communication link between the patient monitoring device and the medical device is disconnected, and after the communication link is disconnected, the pairing relationship is not disassociated at the same time. The patient monitoring device can still maintain the pairing relationship, which means that the configuration information required for establishing the communication link between the patient monitoring device and the medical device is retained, such as the identification of the medical device and the password required for establishing the communication link. In short, the pairing relationship not only represents the object device for establishing the communication link, but also represents the configuration information required for establishing the communication link with the object device. For example, the patient monitoring device retains [pump1, password1], which can be seen as the patient monitoring device maintaining the pairing relationship with the infusion pump pump1, and the password required for establishing the communication link is password1.

[0173] In the application scenario of the embodiment of the present application, the patient monitoring device is configured to further terminate its pairing relationship with the medical device after disconnecting the first communication link with the medical device. Of course, the patient monitoring device can also be configured to disconnect the first communication link with the medical device while maintaining the pairing relationship with the medical device.

[0174] Application scenario 2: When disassociating a patient monitoring device from a patient, maintain the pairing relationship with the medical device to facilitate quick connection to the medical device when associating the next patient.

[0175] In the embodiments provided above, the patient monitoring device can directly terminate the pairing relationship with the medical device or directly maintain the pairing relationship with the medical device based on the configuration. In actual applications, the patient monitoring device can also determine whether to maintain the pairing relationship and maintain the pairing relationship with the device if certain conditions are met.

[0176] like Figure 11 As shown, Figure 10 The difference of the embodiment provided is that after determining the operation instruction to release the association with the patient, the patient monitoring device further determines that the patient monitoring device and the medical device are in a paired lock state, thereby disconnecting the first communication link and maintaining the paired relationship with the medical device. It should be noted that other descriptions of the embodiments of this application can be found in Figure 10 The description is not repeated here.

[0177] For example, the pairing lock state may be set by a device operator on a patient monitoring device or medical device. For example, the device operator inputs a lock command into the patient monitoring device to set the patient monitoring device and a medical device to a pairing lock state. Alternatively, the pairing lock state may be set on the patient monitoring device or medical device by another device, such as a central information system.

[0178] The patient monitoring device may determine that the patient monitoring device and the medical device are in a pairing-locked state in two ways, including but not limited to the following: the patient monitoring device may obtain status information about the patient monitoring device and the medical device, where the status information indicates that the patient monitoring device and the medical device are in a pairing-locked state. Alternatively, the patient monitoring device may determine whether the patient monitoring device and the medical device are in a pairing-locked state, and if so, determine that the patient monitoring device and the medical device are in a pairing-locked state.

[0179] In the solution provided in this embodiment, when a patient monitoring device is disassociated from a patient, its communication link with the medical device is severed, but its pairing relationship with the medical device is maintained. As previously mentioned, a pairing relationship not only represents the device with which the communication link is established, but also the configuration information required to establish a communication link with the device. The purpose of maintaining this pairing relationship is to allow the patient monitoring device to directly use the pairing relationship to establish a communication link with the medical device when it is associated with the next patient.

[0180] For example, the patient monitoring device is currently disassociated with patient A, and the patient monitoring device determines that it is in a pairing lock state with bedside medical devices such as infusion pumps, anesthesia machines, ventilators, etc., then the communication link with these bedside medical devices is disconnected, and the pairing relationship with these bedside medical devices is maintained, so that when patient B is associated, the pairing relationship is used to directly establish a communication link between all bedside medical devices and the patient monitoring device to achieve comprehensive monitoring of patient B. It should be noted that the medical devices in the pairing lock state can be all bedside medical devices connected to the patient monitoring device, or can be certain specified bedside medical devices.

[0181] Of course, on the basis of the embodiments of the present application, if the patient monitoring device determines that it is not in a pairing lock state with the medical device, the first communication link is disconnected and the pairing relationship with the medical device is disassociated.

[0182] Application scenario three: when the communication link of the medical device is abnormally disconnected, the patient monitoring device maintains the pairing relationship with the medical device, so that when the communication link is restored to a connectable state, the pairing connection is automatically re-established.

[0183] As shown in FIG. 6, unlike the embodiments provided in the foregoing application scenarios, the patient monitoring device determines that the first communication link is abnormally disconnected and that the patient monitoring device is in a pairing suspended state with the medical device, and the patient monitoring device maintains the pairing relationship with the medical device. It should be noted that other descriptions related to the embodiments of the present application can be referred to the descriptions of FIG. 5, and will not be described herein. Figure 12 Figure 10 Figure 10

[0184] The medical device can be abnormally disconnected from the first communication link with the patient monitoring device due to various reasons, for example, when the distance between the medical device and the patient monitoring device exceeds a certain distance range, or the communication signal between the medical device and the patient monitoring device is interfered, etc. It can be understood that in the scenario of abnormal disconnection, the patient monitoring device does not actively disconnect the communication link according to the instructions of the device operator, but the passive disconnection of the communication link in the connected state is caused by external factors.

[0185] ​​​The patient monitoring device controls the man-machine interaction device to display alarm information representing the abnormal disconnection of the first communication link when determining the abnormal disconnection of the first communication link, so as to prompt the abnormal connection state. After receiving the alarm information, the device operator inputs a control instruction to the patient monitoring device according to the current use state of the medical device. For example, the medical device has completed the pairing use with the patient monitoring device, and the device operator inputs an alarm confirmation instruction to the patient monitoring device to stop the output of the alarm information. After receiving the alarm confirmation instruction, the patient monitoring device releases the pairing relationship with the medical device. For another example, the medical device has not completed the pairing use with the patient monitoring device, but temporarily follows the patient to go out of the ward for examination or appears other similar clinical conditions, the device operator inputs an alarm confirmation instruction to the patient monitoring device to stop the output of the alarm information, and inputs a suspension instruction to the patient monitoring device to set the patient monitoring device and the medical device in a pairing suspension state. For another example, the patient monitoring device outputs the alarm information for a preset time length, and does not receive the alarm confirmation instruction of the device operator, so as to automatically maintain the pairing relationship or release the pairing relationship.

[0186] When the patient monitoring device determines that the medical device is in the pairing suspension state, the pairing relationship is maintained. The pairing relationship is used to re-establish the first communication link between the patient monitoring device and the medical device when the patient monitoring device and the medical device are restored to the connectable state.

[0187] The medical device can generate medical data associated with the patient during the interruption of the first communication link. After the patient monitoring device determines that the first communication link is re-established, the medical data during the interruption of the first communication link is acquired through the first communication link, so as to ensure the integrity of the medical device.

[0188] In order to ensure the application and implementation of the above method in practice, the embodiments of the present application provide the following device embodiments.

[0242] The internal circuit of the parameter processing module is placed in the housing, such as Figure 13 As shown, it includes a signal acquisition circuit 612 corresponding to at least two physiological sign parameters, a front-end signal processing circuit 613 and a main processor 615.

[0243] The main processor 615 can implement each processing-related step in each of the above-mentioned apnea event monitoring methods.

[0244] The signal acquisition circuit 612 can be selected from an electrocardiogram circuit, a respiratory circuit, a body temperature circuit, a blood oxygenation circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, etc. These signal acquisition circuits 612 are electrically connected to corresponding sensor interfaces, respectively, and are used to be electrically connected to sensor accessories 611 corresponding to different physiological sign parameters. The output end is coupled to the front-end signal processor, the communication port of the front-end signal processor is coupled to the main processor, and the main processor is electrically connected to the external communication and power supply interface.

[0245] The various physiological parameter measurement circuits can employ general-purpose circuits in the prior art, and the front-end signal processor can complete sampling and analog-to-digital conversion of the output signals of the signal acquisition circuit and output a control signal to control the measurement process of the physiological signals. These parameters include, but are not limited to, electrocardiogram, respiration, body temperature, blood oxygen, non-invasive blood pressure, and invasive blood pressure parameters.

[0246] The front-end signal processor can be implemented by using a single-chip microcomputer or other semiconductor devices, or can be implemented by using an ASIC or an FPGA. The front-end signal processor can be powered by an isolated power supply. After the sampled data is simply processed and packaged, the data is transmitted to the main processor through an isolated communication interface. For example, the front-end signal processor circuit can be coupled to the main processor 615 through the isolated power supply and the communication interface 614.

[0247] The front-end signal processor is powered by an isolated power supply. The reason is that the DC / DC power supply is isolated by a transformer, which plays a role in isolating the patient from the power supply equipment. The main purpose is: 1. Isolate the patient. By using an isolation transformer, the application part is floating ground, so that the patient leakage current is small enough; 2. Prevent the voltage or energy of the defibrillator or electrosurgical instrument from affecting the board and devices of the intermediate circuit (guaranteed by the creepage distance and electrical clearance).

[0248] The main processor completes the calculation of the physiological parameter, and transmits the calculation results and waveforms of the parameters to the host computer (such as a host computer with a display, a PC, a central station, etc.) through the external communication and power supply interface. The external communication and power supply interface 616 can be one or a combination of the following: an Ethernet (Ethernet), a Token Ring (Token Ring), a Token Bus (Token Bus), and a local area network interface constituted by a fiber distributed data interface (FDDI) as a backbone network of the three networks; or one or a combination of the following wireless interfaces: infrared, Bluetooth, wifi, WMTS communication, or one or a combination of the following wired data connection interfaces: RS232, USB, etc.

[0249] The external communication and power supply interface 616 can also be one or a combination of a wireless data transmission interface and a wired data transmission interface. The host computer can be a host computer of a monitor, an electrocardiograph, an ultrasonic diagnostic instrument, a computer, or any other computer device. When the software is installed and matched, a monitoring device can be formed. The host computer can also be a communication device, such as a mobile phone. The parameter processing module transmits data to the mobile phone supporting Bluetooth communication through the Bluetooth interface, so as to realize remote transmission of data.
