[0037] Embodiments of the invention

[0038] Embodiments of the present invention

[0039] The present invention 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 for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is 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 according to the description in the specification and the general technical knowledge in the art.

[0040] 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 interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0041] The serial numbers of the components 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).

[0042] The present invention provides a bedside interconnection system, which includes multiple bedside medical devices. The multiple bedside medical devices all communicate through a communication network of the bedside interconnection system. The bedside medical device may include a monitor, an electrocardiograph, an ultrasonic imaging device, an anesthesia machine, a ventilator, an infusion pump, and a defibrillator. It can be seen that multiple bedside medical devices form a bedside interconnection system, which can realize the interconnection between the multiple bedside medical devices.

[0043] When establishing a bedside ear connection system, a bedside medical device establishes a communication connection with another bedside medical device, and the bedside medical device establishes a binding relationship with the other bedside medical device through preset verification information, thereby forming an initial bedside interconnection system. The verification information can be NFC (near field communication) information, that is, two bedside medical devices can establish a binding relationship through near field communication. The verification information can also be code scanning information, that is, a bedside medical device can establish a binding relationship by scanning the QR code or barcode of another bedside medical device. The verification information can also be Bluetooth information, and the two bedside medical devices are connected through Bluetooth to establish a binding relationship. The verification information can also be an ID or pairing code manually entered by the user, and a bedside medical device verifies the ID or pairing code of another bedside medical device, and a binding relationship is established if the verification is passed. Of course, the verification information can also be other data or information, as long as it can ensure the safe and controllable binding of the bedside medical device.

[0044] When the bedside interconnection system adds a bedside medical device, a bedside medical device in the bedside interconnection system establishes a communication connection with the bedside medical device to be added, and establishes a binding relationship with the bedside medical device to be added through preset verification information to add the bedside medical device to be added to the bedside interconnection system. The specific process is the same as the above-mentioned process of establishing the bedside interconnection system, and will not be repeated here.

[0045] In the bedside interconnection system, each bedside medical device establishes a communication connection (physical connection, which can be a wireless connection or a wired connection) with at least one bedside medical device to form a communication network, so that any two bedside medical devices in the bedside interconnection system have a corresponding communication path. The communication path includes multiple nodes, each node corresponds to a bedside medical device, and each of the multiple nodes has the same or different communication connection with the two adjacent nodes. Figure 1 As shown, the communication path between the first bedside medical device 10 and the second bedside medical device 20 includes: communication connection a, node 30, communication connection c, node 40 and communication connection f. The present invention does not limit the communication connection mode between any two bedside medical devices. For example, the communication connection may include at least one of Ethernet connection, wireless network WIFI connection, wireless medical telemetry service WMTS connection, Bluetooth connection, infrared connection, serial port connection, Internet of Things IoT connection, controller area network CAN connection and universal serial bus USB connection. For example, the communication connection between the first bedside medical device 10 and the third bedside medical device 30 is a Bluetooth connection, and the communication connection between the third bedside medical device 30 and the fourth bedside medical device 40 is a wireless network WIFI connection, etc., which is not limited by the present invention.

[0046] Since there may be multiple communication connection modes in the bedside interconnection system, which are different from the traditional communication networking mode, it is necessary to improve the ear connection and communication. The present invention provides two modes, which are introduced one by one below.

[0047] In the first method, data transmission adopts traversal method, such as Figure 1 In the embodiment, the first bedside medical device 10 sends a first request to all adjacent bedside medical devices (only the third bedside medical device 30). When the third bedside medical device 30 receives the first request, it determines whether it satisfies the first request; when the third bedside medical device 30 determines that it satisfies the first request, the third bedside medical device 30 responds to the first request; when the third bedside medical device 30 determines that it does not satisfy the first request, the third bedside medical device 30 forwards the first request through the communication network, for example, forwards it to all adjacent bedside medical devices (the seventh bedside medical device 70 and the fourth bedside medical device 40). After receiving the first request, the seventh bedside medical device 70 and the fourth bedside medical device 40 also determine whether they meet the first request. If they meet, they respond, and if they do not meet, they forward it to all adjacent bedside medical devices. And so on, until all bedside medical devices receive the first request and complete the transmission of the first request. At this time, either at least one bedside medical device in the system responds to the first request, or no bedside medical device in the system can respond to the first request. In this way, the information transmission efficiency is not high, so the present invention provides a second way.

[0048] In the second method, each bedside medical device identifies the topological structure of the bedside interconnection system and determines the communication path according to the topological structure, thereby transmitting information in a targeted manner and improving communication efficiency. The specific process is as follows: Figure 4 As shown, including:

[0049] Step 01, each bedside medical device sends its own device information to the adjacent bedside medical devices (adjacent in topology, i.e., bedside medical devices directly connected together), that is, each bedside medical device sends its own device information to each of its own communication connections. The device information can be information used to uniquely identify the bedside medical device, such as ID, device name, model, etc.

[0050] Step 02: Each bedside medical device receives device information sent by adjacent bedside medical devices through its own communication connections (at least one communication connection), identifies the device information of bedside medical devices reachable by each of its own communication connections, and records it. Figure 1 In the example, the third bedside medical device 30 recognizes that its communication connection a can reach the first bedside medical device 10, the communication connection b can reach the seventh bedside medical device 70, and the communication connection c can reach the fourth bedside medical device 40.

[0051] Step 03, each bedside medical device sends its recorded communication connection and the device information of the bedside medical devices reachable by the communication connection to the adjacent bedside medical device. In other words, each bedside medical device sends the device information of other bedside medical devices reachable by the communication connection (i.e. the device information of each bedside medical device reachable by the communication connection recorded by the bedside medical device) through its own communication connection. For example Figure 1 In the example, the fourth bedside medical device 40 sends to the communication connection c: the sixth bedside medical device 60 can be reached through the communication connection d of the fourth bedside medical device 40, the communication connection e can reach the fifth bedside medical device 50, and the communication connection f can reach the second bedside medical device 20.

[0052] Step 04, each bedside medical device, that is, for any bedside medical device in the bedside interconnection system, the bedside medical device receives the device information of each reachable bedside medical device of the adjacent bedside medical device sent by the adjacent bedside medical device; the bedside medical device records the information of the communication connection reaching the adjacent bedside medical device and the corresponding device information of each reachable bedside medical device. That is, the bedside medical device updates the recorded communication connection and the device information of the reachable bedside medical device, and then returns to step 03, that is, repeats steps 03 and 04 until the recorded device information of the reachable bedside medical device of each communication connection does not change. In this way, each bedside medical device records all the communication connections and the device information of the reachable bedside medical devices, that is, each bedside medical device obtains the topological structure information of the entire bedside interconnection system; thus, it is beneficial to plan the communication path in the subsequent communication process. In the topological structure information, the communication connection and the device information of the reachable bedside medical device are associated, which is convenient for planning the communication path.

[0053] If a new bedside medical device is added to the bedside interconnection system, for the sake of convenience, the third bedside medical device 30 is newly bound to a bedside medical device (the seventh bedside medical device 70) as an example for explanation. The third bedside medical device 30 establishes a communication connection b with the seventh bedside medical device 70, and the third bedside medical device 30 records the device information of the seventh bedside medical device 70 reachable by the communication connection b, that is, the topological structure information of the bedside interconnection system is updated. The third bedside medical device 30 can send the communication connection b (communication connection information) and the device information of the seventh bedside medical device 70 reachable by the communication connection b to the adjacent bedside medical devices (such as 10, 40 and 70), that is, the method of steps 03 and 04 can be adopted, and after one or more cycles, the topological structure information of all bedside medical devices (including the seventh bedside medical device 70) is updated. Of course, the third bedside medical device 30 can also broadcast its updated topological structure information to all bedside medical devices (including the seventh bedside medical device 70), so that the topological structure information of all bedside medical devices is updated. In this way, bedside medical equipment can be easily added and plug-and-play can be achieved.

[0054] The present invention will be described later using the second method as an example. There are many data processing methods for bedside medical devices in the bedside interconnection system, which are introduced one by one below. Figure 2 As shown, a data processing method involves at least two bedside medical devices, which are referred to as a first bedside medical device 10 and a second bedside medical device 20 for ease of description. Figure 1 The bedside interconnection system shown includes at least a first bedside medical device 10 and a second bedside medical device 20 . Figure 2 The data processing method shown comprises the following steps:

[0055] Step 1: When the first bedside medical device 10 triggers a preset event, the first bedside medical device 10 sends a first message to a bedside medical device corresponding to the preset event among multiple bedside medical devices through a communication network. Since the first bedside medical device 10 and the second bedside medical device 20 are both one of the multiple bedside medical devices, the two may be adjacent or not adjacent on the communication path, and this embodiment is described by taking the latter as an example. A bedside medical device between the first bedside medical device 10 and the second bedside medical device 20 is called a third bedside medical device 30. In step 1, the first bedside medical device 10 sends a first message to a bedside medical device corresponding to the preset event among the multiple bedside medical devices through the communication network and the third bedside medical device 30 in the bedside interconnection system. The preset event can be set by the system or by the user. For example, the preset event can be an instruction input by the user through a human-computer interaction device, the preset event can be a specific time point, and the preset time can be the generation of specific information such as the generation of the first information, etc.

[0056] Step 2: When the second bedside medical device 20 of the bedside medical system corresponds to a preset event, the second bedside medical device 20 receives and responds to the first information.

[0057] Since each bedside medical device has obtained the topological structure information, any two bedside medical devices can communicate with each other in a targeted manner. It is only necessary to attach the device information of the destination bedside medical device to the data to be sent, that is, mark which bedside medical device to send to on the data to be transmitted. In other words, the first information contains the device information of the destination bedside medical device, then Figure 2 The method shown also includes the following steps:

[0058] If the destination bedside medical device (for example, the second bedside medical device 20) is adjacent to the first bedside medical device 10, the first bedside medical device 10 sends the first information, and the destination bedside medical device receives it.

[0059] If there are one or more other bedside medical devices between the first bedside medical device 10 and the destination bedside medical device, the first bedside medical device 10 and each bedside medical device between the first bedside medical device 10 and the destination bedside medical device need to determine which communication connection to use to transmit the first information.

[0060] Specifically, if the first bedside medical device 10 has only one communication connection, the first information can be sent directly through the communication connection. If there are multiple communication connections, a communication connection is determined based on the topology information and the device information of the destination bedside medical device. The determined communication connection can reach the (indirect) destination bedside medical device, and the first bedside medical device 10 sends the first information through the determined communication connection.

[0061] Since the bedside medical devices between the first bedside medical device 10 and the target bedside medical device are universal, one of the bedside medical devices is taken as an example for explanation. Assuming that it is the fourth bedside medical device 40, the process of sending the first information is as follows: Figure 5 As shown, the following steps are included:

[0062] Step 1.1, the fourth bedside medical device 40 receives the first information through the first communication connection, the fourth bedside medical device 40 is one of the multiple bedside medical devices, and the first communication connection is a communication connection between one of the bedside medical devices adjacent to the fourth bedside medical device and the fourth bedside medical device 40 ( Figure 1 The first communication connection is c).

[0063] Step 1.2, the fourth bedside medical device 40 determines a second communication connection based on the topology information and the device information of the destination bedside medical device. The second communication connection is a communication connection between the fourth bedside medical device 40 and one of the devices adjacent to the fourth bedside medical device 40. The topology information records the device information of the bedside medical devices reachable by the fourth bedside medical device 40 and the corresponding communication connection information.

[0064] Step 1.3: The fourth bedside medical device 40 sends the first information via the second communication connection. Since each bedside medical device will execute Figure 5 The process shown, therefore, the forwarding of information only needs to consider the communication connection with the next bedside medical device, and has nothing to do with the communication connection of other bedside medical devices, so that the entire bedside interconnection system can have a variety of communication connection methods. There is no need to consider the problem of limited communication connection for newly added bedside medical devices. For example, if the newly added bedside medical device has only one communication connection method, it is only necessary to find another bedside medical device in the system that can match the communication connection, and then the newly added bedside medical device can be added to the system. The interconnection between devices is very convenient, and the applicable scenarios are broad, and a variety of applications can be expanded. In particular, various bedside medical devices in hospitals are usually produced by different manufacturers, and most of them are incompatible. The method provided by the present invention can achieve communication interconnection, and can be quickly and widely used in various hospitals and medical institutions at present, and has broad application prospects.

[0065] by Figure 1 For example, before the fourth bedside medical device 40 receives the first information, the third bedside medical device 30 may also receive the first information according to Figure 5 The steps shown forward the first information to a fourth bedside medical device 40 .

[0066] If the second bedside medical device 20 is the destination bedside medical device, it only needs to receive the first information and respond, for example, store the first information, display the first information, display the first information together with its own information, etc., thereby realizing data sharing and integration among various devices.

[0067] Of course, there may be more than one target bedside medical device. For example, when the device information of the target bedside medical device of the first information is the device information of the second bedside medical device group (including at least two bedside medical devices), the fourth bedside medical device 40 determines the third communication connection corresponding to each bedside medical device in the second bedside medical device group according to the topology information and the device information of the second bedside medical device group; and then sends the first information through each corresponding third communication connection.

[0068] For another example, when the device information of the destination bedside medical device of the first information is the device information of at least two bedside medical devices, the fourth bedside medical device 40 determines the third communication connection corresponding to each of the at least two bedside medical devices according to the topology information and the device information of the at least two bedside medical devices, and then sends the first information through each corresponding third communication connection. It can be seen that the multi-purpose transmission of the first information is achieved, and the communication process is convenient and fast.

[0069] Of course, any bedside medical device can broadcast information. For example, when the device information of the destination bedside medical device of the first information is the device information of the preset bedside medical device, the fourth bedside medical device 40 sends the first information through the communication connection between all bedside medical devices adjacent to the fourth bedside medical device 40. In other words, a special destination bedside medical device (preset bedside medical device) can be defined to indicate that this needs to be sent to all bedside medical devices. In step 1.2, when the bedside medical device determines which communication connection the first information should be sent to, the device information of this special destination bedside medical device is considered to need to be sent to all communication connections except the communication connection that receives the first information. The transmission path of the first information is as follows. Figure 6 As shown by the arrow, the broadcast of the first information is realized, and the information transmission is very convenient.

[0070] In this embodiment, the first information includes at least one of patient physiological data (such as various physiological parameter data, corresponding waveforms, etc.), patient information, device information, device status, and alarm information. Patient information includes, but is not limited to: name, medical record number, height and weight, etc. For example, the bedside interconnection system can serve a patient. If one of the bedside medical devices generates patient physiological data, patient information, or alarm information, etc., then the other one or all bedside medical devices can know it. Medical staff only need to concentrate on checking one bedside medical device to understand the overall situation of the patient, which is very convenient. For another example, when a bedside medical device in the bedside interconnection system obtains patient information, the patient information is sent to each bedside medical device in the bedside interconnection system through the communication network. In this embodiment, when the patient information is the patient information of a newly added patient or the updated patient information of an existing patient, the patient information is sent to each bedside medical device in the bedside interconnection system through the communication network. That is, the new patient information is broadcasted, so that medical staff do not need to manually enter new patient information in each device, reducing the workload of medical staff.

[0071] Figure 2 The data processing method shown in FIG. 1 can be applied to data between devices. The present invention can also be applied to data subscription and acquisition. The corresponding data processing method is as follows: Figure 3 As shown, the following steps are included:

[0072] Step 1', the first bedside medical device 10 sends a first request through the communication network. Since the first bedside medical device 10 and the second bedside medical device 20 are both one of the multiple bedside medical devices, the two may be adjacent or not adjacent on the communication path, and this embodiment is described using the latter as an example. A bedside medical device between the first bedside medical device 10 and the second bedside medical device 20 is called a third bedside medical device 30, then in step 1, the first bedside medical device 10 sends a first request through the communication network and the third bedside medical device 30 in the bedside interconnection system. Figure 1 In the process, since there is a fourth bedside medical device 40 on the communication path, the first bedside medical device 10 sends a first request through the communication network, the third bedside medical device 30 and the fourth bedside medical device 40.

[0073] The first bedside medical device 10 sends a first request through the communication network and the third bedside medical device 30 in the bedside interconnection system. Specifically, the request may be as follows: Figure 2 As in the first information of the embodiment, a first request is sent to the second bedside medical device 20 through the communication network and the third bedside medical device 30; or Figure 2 As in the first information of the embodiment, a first request is sent to a first bedside medical device group in the bedside interconnection system through a communication network, and the first bedside medical device group includes at least two bedside medical devices; it can also be as Figure 2 The first request is broadcasted through the communication network as in the first information of the embodiment. Figure 2 The first information of the embodiment will not be elaborated here.

[0074] Step 2', when the second bedside medical device 20 receives the first request through the communication network, the second bedside medical device 20 determines whether it satisfies the first request. When the second bedside medical device 20 determines that it satisfies the first request, the second bedside medical device 20 responds to the first request through the communication network. The first bedside medical device 10 may send the first request in the form of a broadcast, such as Figure 6 As shown, the first bedside medical device 10 waits for responses from other bedside medical devices. If the first bedside medical device 10 knows that the second bedside medical device 20 can satisfy the first request, it can also use it as the destination bedside medical device and send the first request. The process of transmitting the first request from the first bedside medical device 10 to the second bedside medical device 20 can be the same as the transmission process of the first information in the above embodiment, which will not be repeated here.

[0075] In this embodiment, the first request is a request for obtaining the second information. When the second bedside medical device 20 determines that it satisfies the first request, responding to the first request through the communication network includes: when the second bedside medical device 20 determines that the second information corresponding to the first request is obtainable, obtaining the second information and sending it to the first bedside medical device through the communication network. The second information can be generated by the second bedside medical device 20, or obtained by the second bedside medical device 20 from an external device.

[0076] Specifically, when the second bedside medical device 20 sends the second information, its device information may be attached. Thus, the first bedside medical device 10 records the correspondence between the first request and the device information of the second bedside medical device 20. When the first bedside medical device 10 subsequently requests to obtain the second information, it can directly send the first request to the second bedside medical device 20, thereby realizing data subscription. In this embodiment, the second information includes at least one of patient physiological data, patient information, device information, device status, and alarm information. It can be seen that the bedside medical device subscribes to the information of other bedside medical devices, which is essentially to use the capabilities of other bedside medical devices for its own benefit and expand the functions of the bedside medical devices.

[0077] Of course, the second bedside medical device 20 can also record the correspondence between the first request and the first bedside medical device. When the second bedside medical device 20 obtains the second information corresponding to the first request, it sends the second information to the first bedside medical device through the communication network. This realizes the active transmission of data. The second bedside medical device 20 sends the second information to the first bedside medical device 10, and its data transmission path is as follows: Figure 7 As shown, the principle is the same as the sending process of the first request (the destination bedside medical device is set to the first bedside medical device), and will not be elaborated here.

[0078] It can be seen that the present invention can realize automatic and timely synchronization of the first information and the second information through a unified data subscription and publishing mechanism, so as to realize barrier-free and transparent (regardless of the communication connection mode and connection topology between the devices) data sharing between the devices in the system, and can realize various integrated services based on this. For example, in the lung recruitment function of the ventilator, the SpO2 (blood oxygen saturation) value shared by the monitor can be used to assist in judgment; the ultrasonic equipment can also use the respiratory waveform of the ventilator and the electrocardiogram waveform of the monitor for auxiliary diagnosis.

[0079] The present invention can also achieve capability sharing through interconnection between devices. For example, sharing of communication capabilities. For example, the first request is a request for external communication. When the second bedside medical device 20 determines that the first request is met, the second bedside medical device 20 responds to the first request through the communication network, including: when the second bedside medical device 20 determines that it has the function of external communication, it returns response information to the first bedside medical device 10 through the communication network; the second bedside medical device 20 thereby receives the data sent by the first bedside medical device 10 through the communication network and sends it to the outside; the second bedside medical device 20 receives external data and sends it to the first bedside medical device 10 through the communication network, and the transmission of data is as follows: Figure 8 As shown. It can be seen that although the first bedside medical device 10 does not have the ability to communicate with the outside, it can communicate with the outside with the help of the second bedside medical device 20. Of course, the second bedside medical device 20 can also be specified by the user, that is, the user specifies the second bedside medical device 20 to communicate with the outside, and the second bedside medical device 20 receives the data sent by the first bedside medical device 10 through the communication network and sends it to the outside; receives external data and sends it to the first bedside medical device 10 through the communication network.

[0080] The second bedside medical device 20 serves as a transfer device for the entire bedside interconnection system, and the communication methods with the outside include but are not limited to: wired network, WIFI, Bluetooth, 4G\5G and other communication methods. In the ward, there are multiple devices beside the bed, and only one device (such as a monitor) may be able to connect to the Internet (access the hospital network). Other devices can form a bedside interconnection system with the device through wired methods such as serial ports and USB, or wireless methods such as infrared, Bluetooth, WMTS, etc., so as to communicate through the device and open up the Internet access to the outside world. In this way, the networking of various medical devices in the hospital is realized.

[0081] In addition to sharing communication capabilities, display capabilities can also be shared. For example, the first request is a request to display data. When the second bedside medical device 20 determines that the first request is met, the second bedside medical device 20 responds to the first request through the communication network, including: when the second bedside medical device 20 determines that it has a display function, it returns a response message to the first bedside medical device 10 through the communication network; the second bedside medical device 20 receives the data to be displayed sent by the first bedside medical device 10 through the communication network; the second bedside medical device 20 displays the data to be displayed, and of course, the data to be displayed and the data of the second bedside medical device 20 itself can also be integrated. For example, the monitor integrates the breathing-related treatment parameters of the ventilator and anesthesia machine into the main interface, and displays them together with the patient's physiological parameter data, so that medical staff can comprehensively judge the patient's condition, cause of disease, etc.

[0082] The present invention can also share printing capabilities, for example, the first request is a printing request. When the second bedside medical device 20 determines that the first request is met, the second bedside medical device 20 responds to the first request through the communication network, including: when the second bedside medical device 20 determines that it has a printing function, it returns a response message to the first bedside medical device 10 through the communication network; the second bedside medical device 20 receives the information to be printed sent by the first bedside medical device 10 through the communication network; the second bedside medical device 20 prints the information to be printed. In the prior art, all devices are usually connected to the printer via broadband, while the devices in the bedside interconnection system of the present invention are not limited to the communication connection method, and even do not require a special printer. Shared printing can be achieved using a bedside medical device with a printing function.

[0083] The present invention can also share storage capabilities. For example, the first request is a storage request. When the second bedside medical device 20 determines that the first request is satisfied, the second bedside medical device 20 responds to the first request through the communication network, including: when the second bedside medical device 20 determines that it has a storage function, it returns a response message to the first bedside medical device 10 through the communication network; the second bedside medical device 20 receives the data to be stored sent by the first bedside medical device 10 through the communication network; the second bedside medical device 20 stores the data to be stored.

[0084] The present invention can also share computing and analysis capabilities. For example, the first request is a data computing and analysis request. When the second bedside medical device 20 determines that the first request is met, the second bedside medical device 20 responds to the first request through the communication network, including: when the second bedside medical device 20 determines that it has data computing and analysis capabilities, it returns response information to the first bedside medical device 10 through the communication network; the second bedside medical device 20 receives the data to be calculated and analyzed sent by the first bedside medical device through the communication network; the second bedside medical device 20 performs computing and analysis on the data to be calculated and analyzed; the second bedside medical device 20 sends the computing and analysis results to the first bedside medical device 10 through the communication network.

[0085] Figure 3 In the method shown, after the first bedside medical device 10 sends a first request, the third bedside medical device 30 determines whether it satisfies the first request when receiving the first request; when the third bedside medical device 30 determines that it satisfies the first request, the third bedside medical device 30 responds to the first request; when the third bedside medical device 30 determines that it does not satisfy the first request, the third bedside medical device 30 forwards the first request through the communication network. Similarly, if there are other bedside medical devices between the first bedside medical device 10 and the second bedside medical device 20, such as the fourth bedside medical device 40, the functions of the third bedside medical device 30 in this paragraph are also performed, which will not be repeated here.

[0086] The second bedside medical device 20 receives the first request and determines whether it satisfies the first condition. When the second bedside medical device 20 determines that it does not satisfy the first request, it forwards the first request to the next bedside medical device in the bedside interconnection system, and the next bedside medical device is a device other than the first bedside medical device 10, the second bedside medical device 20 and the third bedside medical device 30 among the multiple bedside medical devices. The next bedside medical device receives the first request; when the next bedside medical device determines that it satisfies the first request, the next bedside medical device responds to the first request through the communication network; when the next bedside medical device determines that it does not satisfy the first request, the next bedside medical device forwards the first request to the next bedside medical device of the next bedside medical device through the communication network; when the next bedside medical device determines that it does not satisfy the first request, and the next bedside medical device is the last device of the forwarding path for forwarding the first request, it means that there is no bedside medical device in the system that can satisfy the first request, and the next bedside medical device feeds back information indicating that the first request cannot be satisfied to the first bedside medical device through the communication network.

[0087] There is a need for remote operation and control of equipment such as ventilators, anesthesia machines, and infusion pumps, but this type of remote control application is very risky. It is necessary to ensure that the control commands come from authorized and trusted devices and that the control commands are not tampered with during transmission. Through the device pairing mechanism and the unified authorization and authentication mechanism, secure and controllable remote operation and control between devices within the interconnected system can be achieved.

[0088] Specific implementation plans include Fig. 9 As shown, it includes three parts: a reliable communication link layer 93, a secure data transmission layer 92, and a secure application layer 91. The upper layer is constructed using the functions provided by the lower layer. Among them, the communication link layer 93 is responsible for providing a reliable communication link and shielding the upper layer from the differences in specific communication connection methods (such as serial port, Bluetooth, network); the data transmission layer 92 is responsible for providing secure data transmission that is anti-sniffing and interception, anti-data forgery and tampering, and anti-data packet recording and playback. The specific implementation method can directly use the standard SSL / TLS ("Secure Sockets Layer" protocol / "Secure Transport Layer" protocol). The application layer 91 is responsible for providing security applications such as identity authentication, authority management and control.

[0089] In the bedside interconnection system, the communication between bedside medical devices is realized based on the communication connection between two adjacent bedside medical devices. In this embodiment, a communication session is established between two adjacent bedside medical devices and a communication session key is randomly generated. When information needs to be transmitted, the information is encrypted using the communication session key and then transmitted. Taking the first bedside medical device 10 and the third bedside medical device 30 as an example, Figure 1The first bedside medical device 10 and the third bedside medical device 30 establish a communication session and randomly generate a communication session key. The first bedside medical device 10 encrypts the first request or the first information through the communication session key and sends it to the third bedside medical device 30. Specifically, the process is as follows Fig.10 As shown, including:

[0090] The first bedside medical device 10 sends a session establishment request to the third bedside medical device 30, wherein the session establishment request includes a random session ID and an identity of the first bedside medical device 10. The identity can be device information or other identifiers that can uniquely identify a bedside medical device. The communication between two adjacent devices is based on a session, and each session has a random session ID, which can prevent the communication data from being recorded and replayed.

[0091] The third bedside medical device 30 verifies the identity of the first bedside medical device 10. The encoding rules and verification methods of the identity are agreed upon in advance by the two devices (for example, written into the code, or set in user maintenance). In order to prevent data from being forged, when a communication session is established, the identity of the other party is first verified. If the verification fails, the session is terminated directly. After the verification passes, a session response is fed back to the first bedside medical device 10, and the session response includes a session ID, the identity of the third bedside medical device, and the public key of the asymmetric encryption algorithm of the third bedside medical device.

[0092] The first bedside medical device 10 verifies the identity of the third bedside medical device 30, and after the verification is passed, randomly generates a symmetric encryption key for this session. The first bedside medical device 10 uses the public key of the asymmetric encryption algorithm provided by the third bedside medical device to encrypt the session confirmation information, and the session confirmation information includes the session ID and the symmetric encryption key of this session.

[0093] The third bedside medical device 30 decrypts with the private key of the asymmetric encryption algorithm to obtain the session confirmation information, that is, the symmetric encryption key of this session. After that, the communication data between the two, such as the first information and the first request, are encrypted together with the symmetric encryption key of this session after adding the session ID, and then transmitted through the communication connection. In this way, the data is encrypted before transmission, and the encryption key is randomly generated when the session is established to prevent the communication data from being sniffed.

[0094] Above Fig.10 The same process applies to the communication between bedside medical devices and the outside world, so I will not go into details here. It can be seen that when devices communicate with each other and with external systems, identity recognition and permission verification are required to confirm that the other end is legally authorized and that the data has not been tampered with during transmission, ensuring that the business based on device interconnection is safe and controllable.

[0095] To achieve application layer security and prevent unauthorized control of devices and unauthorized access to private data, you can Fig.11 The operations shown. This section focuses on the security of application business interactions between any two (not necessarily adjacent) bedside medical devices. The key to this section is to identify whether the other party is authorized. One solution is to use an authorization code, for example, the first request or the first information includes an authorization code. The authorization code is generated by the second bedside medical device 20 based on the user's preset operation. The second bedside medical device 20 responds to the first request or the first information, including: the second bedside medical device 20 verifies the authorization code, and responds to the first request or the first information if the verification is successful. The specific process is as follows Fig.11 As shown, including:

[0096] The user performs preset operations on the second bedside medical device 20, such as for a target scenario, a target time period, and a target operation (such as control, access to private data), so that the second bedside medical device 20 generates a specific string, namely, an authorization code.

[0097] The second bedside medical device 20 generates the authorization code according to the user's preset operation and automatically records the binding relationship with the above information (target scene, target time period, target operation).

[0098] When the user uses the first bedside medical device to control the second bedside medical device or access private data, the user enters the authorization code into the first bedside medical device.

[0099] The first bedside medical device Fig.10 The secure transmission mechanism in the , sends the operation request (including the target scene, target time period, target operation, etc.) and the above authorization code to the second bedside medical device. The first bedside medical device and the second bedside medical device may not be adjacent devices, that is, they may have been transferred through many devices, and the transfer can also be adopted Fig.10 secure transmission mechanism.

[0100] The second bedside medical device verifies whether the received operation request matches the target scene, target time period, and target operation corresponding to the authorization code. If they match, the operation request is accepted, otherwise it is rejected; whether it is accepted or rejected, a result is returned to the first bedside medical device. The operation request can be a control instruction for controlling the bedside medical device to perform various functions, or it can be the above-mentioned first information, first request, etc.

[0101] In order to ensure that the data between various devices can be used safely and correctly for various converged services, time synchronization can be performed between devices so that the data from different devices are aligned in the time dimension. Any bedside medical device in the bedside interconnection system can initiate time synchronization. For the convenience of description, the bedside medical device that initiates time synchronization is called the fifth bedside medical device. The fifth bedside medical device can be specified by the user or determined by negotiation according to preset rules by the bedside interconnection system. The fifth bedside medical device sends a characteristic signal to each bedside medical device in the bedside interconnection system through the communication network, so that each bedside medical device after receiving the characteristic signal performs clock synchronization with the fifth bedside medical device according to the characteristic signal. After receiving the characteristic signal, each bedside medical device performs clock reference alignment. Clock reference alignment means that all devices take this moment as the same time point. The time point can be a fixed time (such as time 0); or a time negotiated between devices (for example, the device sending the characteristic signal tells other devices).

[0102] Fifth, the timing for the bedside medical device to send the characteristic signal can be manual triggering, or triggering when the system is initialized, or triggering when a new device is added to the bedside interconnection system, or periodic triggering, etc.

[0103] Fifth, the bedside medical device sends a characteristic signal to each bedside medical device in the bedside interconnection system through the communication network. For example, the following method may be used:

[0104] The fifth bedside medical device sends a delay detection signal to each bedside medical device in the bedside ear connection system through the communication network, and receives a feedback signal from each bedside medical device based on the delay detection signal.

[0105] like Fig.12 As shown, the fifth bedside medical device calculates the transmission delay corresponding to each bedside medical device according to the time t1 of sending the delay detection signal and the time t2 of the feedback signal returned by each bedside medical device. Single transmission delay = t2-t1. For more accuracy, this step can be performed multiple times to obtain multiple transmission delays and then take the average value.

[0106] The fifth bedside medical device can send characteristic signals to each bedside medical device with corresponding delays according to the transmission delays corresponding to each bedside medical device, so that each bedside medical device receives the characteristic signal at the same time. Of course, the fifth bedside medical device can also send corresponding transmission delays to each bedside medical device, so that after each bedside medical device receives the characteristic signal, it completes clock synchronization with the fifth bedside medical device according to the transmission delay.

[0107] Since in the bedside interconnection system, each bedside medical device may need to initiate a first request and send a first message, and each bedside medical device may be able to respond to the first request and first message sent by the corresponding bedside medical device, most of the functions mentioned in the above-mentioned bedside medical devices can be possessed by the above-mentioned first bedside medical device, the second bedside medical device, the third bedside medical device, the fourth bedside medical device, the fifth bedside medical device, etc. are only used for illustration.

[0108] Fig.13 The bedside interconnection system shown also includes multiple bedside medical devices, each of which communicates through the communication network of the bedside interconnection system. There are two bedside medical devices in the bedside interconnection system, which are referred to as the first bedside medical device 10 and the second bedside medical device 20 for ease of description. The first bedside medical device 10 and the second bedside medical device 20 may be adjacent or not adjacent in topology. Fig.13 Just for illustration.

[0109] When the first bedside medical device 10 has a need, a first request may be issued through the communication network. When the second bedside medical device 20 receives the first request through the communication network, the second bedside medical device 20 determines whether it satisfies the first request. When it is determined that it satisfies the first request, the second bedside medical device 20 responds to the first request through the communication network.

[0110] When the second bedside medical device 20 determines that it does not meet the first request, it can forward the first request to facilitate other bedside medical devices to respond. For the convenience of description, the bedside medical device to which it is forwarded is referred to as the third bedside medical device 30. That is, when the second bedside medical device 20 determines that it does not meet the first request, the second bedside medical device 20 forwards the first request to the third bedside medical device 30 in the bedside ear connection system. The third bedside medical device can be a device that meets the first request determined by the second bedside medical device; the third bedside medical device can also be a device determined by the second bedside medical device to process the first request. In this way, the first request can be received without the need for the third bedside medical device to make a judgment, so as to respond, which is very suitable for scenarios where the third bedside medical device has insufficient computing and processing capabilities or even no computing and processing capabilities.

[0111] Of course, the third bedside medical device can also make its own judgment like the second bedside medical device. Specifically, the third bedside medical device receives the first request and determines whether it meets the first request. When the third bedside medical device determines that it meets the first request, it responds to the first bedside medical device through the communication network, or responds to the first bedside medical device through the communication network and the second bedside medical device.

[0112] When the third bedside medical device determines that it does not meet the first request, the third bedside medical device may forward the first request to a next bedside medical device of the third bedside medical device among the multiple bedside medical devices through the communication network.

[0113] When the third bedside medical device determines that it does not meet the first request, and the third bedside medical device is the last device of the forwarding path for forwarding the first request, the third bedside medical device feeds back information indicating that the first request cannot be met to the first bedside medical device through the communication network. The first request includes a request for at least one of obtaining second information, communicating with the outside, displaying information, printing information, storing information, and calculating and analyzing information. The specific process of sharing these capabilities can be the same as the above embodiment, and will not be repeated here.

[0114] Of course, the bedside medical devices in the bedside interconnection system can also send various types of information to other bedside medical devices. For example, when the first bedside medical device 10 triggers a preset event, the first bedside medical device 10 sends a first message to the bedside medical device corresponding to the preset event among the multiple bedside medical devices through the communication network. When the second bedside medical device 20 corresponds to the preset event, the second bedside medical device 20 receives and responds to the first message. Fig.13 In the embodiment shown, the data processing method of the bedside medical device is the same in principle and details as Figure 1 The embodiments shown are not described in detail here.
