Abstract

According to the distributed medical monitoring method and system and the monitoring workstation provided by the invention, when the monitoring workstation is in normal communication connection with the server, the monitoring workstation works in the first working mode: obtaining the pre-associated target data of the monitored patient from the server in real time, and presenting the target data of the monitored patient according to the classification of the patient; when the communication connection between the monitoring work station and the server is abnormal, the monitoring work station works in a second working mode: the monitoring work station is in communication connection with first bedside medical equipment to which a pre-associated monitored patient belongs, and target data generated in the working process of the first bedside medical equipment is acquired from the first bedside medical equipment in real time; and displaying the target data of the monitored patient according to the patient classification. Thus, the requirement that hospital data are mainly stored and managed in a centralized mode through the server is met, it is guaranteed that after the connection with the server is abnormal, the monitoring work station can still obtain the target data of the patient in real time for monitoring presentation, and the safety of patient monitoring is improved.

Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a distributed medical monitoring method, system and monitoring workstation. Background Art

[0002] At present, bedside medical devices such as monitors have networking functions. When multiple bedside medical devices in a department are centrally monitored and managed, a common practice is to place a computer at the nurse station and connect it to the network of multiple bedside medical devices. The computer is also used for data storage, centralized monitoring and management. This is the traditional monitoring central station (or infusion pump central station, etc.).

[0003] With the increase in demand and the development of technology, centralized monitoring, remote monitoring, mobile monitoring, etc. are becoming more and more common. At the same time, with the rise of big data, many hospitals also hope to preserve the data of medical equipment for a long time. These needs require that the monitoring central station can support server-based deployment and be placed in the hospital data center or even in the cloud. Some hospitals have begun to deploy servers, and each medical device in the hospital is directly connected to the server, and the generated data is transmitted to the server for storage, and then the server sends the data to the monitoring central station at the nurse station.

[0004] The problem this causes is that if the hospital's main network is paralyzed or the server is abnormal, the central monitoring station placed on the nurse station of the department will not be able to work, and the nurse will not be able to understand the alarm status of the patients in the department in time.

[0005] Therefore, the safety of existing monitoring methods needs to be improved. Summary of the invention

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners adopt related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0043] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0044] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0045] In the prior art, some hospitals would let each bedside medical device be connected to the workstation on the nurse station first, and then connected to the server through the workstation to save data. The workstation or the server distributes this data to other workstations for viewing, etc. However, there are many things on the nurse station, and the computer (workstation) placed here is prone to abnormal power-off, resulting in other workstations being unable to view this data. The distributed medical monitoring system provided by the present invention, in the case of using the server to receive and store the target data generated by each bedside medical device, introduces some risk control measures to ensure the safety and stability of patient monitoring. For example, generally, the server stores the data of each bedside medical device, and the workstation obtains the data of the bedside medical device it manages from the server and displays it. When the communication connection with the server is abnormal, it is changed to directly obtain the data from the bedside medical device and display it. In this way, it not only realizes the storage of all data by the server but also ensures that the workstation can still monitor the patient in case of a network failure.

[0046] For a monitoring workstation, it can be communicatively connected to only one of the server and the associated first bedside medical device at the same time. When an abnormality occurs, it can ensure continuous acquisition of target data by switching the communication connection object. It can also be communicatively connected to both the server and the associated first bedside medical device at the same time. When one of them has an abnormality, the target data provided by the other can be used, and continuous monitoring of the patient can be carried out without being affected by network abnormalities or the like. The following will respectively elaborate on these two situations through some embodiments.

[0047] Embodiment 1. In this embodiment, the distributed medical monitoring system is as Figure 1 shown, including: a server 50, one or more first bedside medical devices 10, and one or more monitoring workstations 60.

[0048] The first bedside medical device 10 is used to be communicatively connected to the server 50 and transmit the target data generated during operation to the server 50, for example, uploading it to the server 50 in real time. The first bedside medical device 10 can be networked and transmit the target data to the server 50 through a network device. The first bedside medical device 10 can be a medical device located beside the bed that provides exclusive medical services to patients, such as a monitor, a ventilator, an anesthetic machine, an infusion pump, etc. It can be seen that the distributed medical monitoring system in this embodiment is applicable to the scenario of in-hospital monitoring. The first bedside medical devices 10 included in the distributed medical monitoring system can be of one or more types, such as including one or more of a monitor, a ventilator, an anesthetic machine, and an infusion pump, and multiple means two or more. The type of target data can be preset. For example, the target data includes: physiological parameter data, parameter alarm information generated based on the physiological parameter data, device operation parameter data, and device alarm information generated based on the device operation parameter data, etc. The types of target data of different types of first bedside medical devices 10 are usually also different. For example, the target data of one type of first bedside medical device 10 (such as a monitor, a ventilator, and an anesthetic machine, etc.) can include the physiological parameter data obtained by detecting the patient's physiological parameters (physiological parameters such as respiration, heartbeat, body temperature, blood pressure, and pulse, etc., and the data can be a numerical value, a change amount, a waveform curve, etc.), and can also include the parameter alarm information generated when judging whether the physiological parameter data is abnormal. The target data of another type of first bedside medical device 10 (such as an infusion pump, etc.) can include device operation parameter data (such as the dosage of medicine, the infusion rate, etc.), and can also include the device alarm information generated when judging whether the device operation parameter data is abnormal.

[0049] The server 50 is used to receive and store the target data sent by the first bedside medical device 10. For example, it receives the target data sent by each first bedside medical device 10, classifies and stores the target data by patient, which is convenient for subsequent summarization, processing, querying, and management of data for each patient. In this way, the data of each medical device in the hospital can be transmitted to the server 50 for long-term storage. The server 50 can also utilize its strong computing power to process a large amount of data in the hospital and provide it for other devices to view, etc. The server 50 also transmits the target data of the monitored patients pre-associated with the monitoring workstation 60 to the monitoring workstation 60. Of course, when the server 50 fails or the communication connection with the monitoring workstation 60 fails, the target data cannot be transmitted to the monitoring workstation 60. This invention will solve this problem through subsequent solutions. The server 50 can be a server placed in the hospital computer room, such as a local data center, or a cloud server, such as a physical or virtual medical device data server in a cloud data center. Using the server 50 to store the data generated by each bedside medical device 10 eliminates the need for the monitoring workstation 60 to store the data, and even if the monitoring workstation 60 fails, it does not affect the storage and transmission of the data. The number of servers 50 is not limited and can be a single unit or a server cluster, etc.

[0050] The monitoring workstation 60 is used to obtain the target data of the first bedside medical device 10 to which each pre-associated monitored patient belongs, and then presents the target data of each monitored patient classified by patient, which is convenient for medical staff to timely grasp the patient's condition. The monitored patients pre-associated with the monitoring workstation 60 are the patients that the monitoring workstation 60 needs to monitor, and the target data of these monitored patients will be displayed. Usually, a patient is associated with their bedside medical device. The monitoring workstation 60 being pre-associated with monitored patients is equivalent to the monitoring workstation 60 being pre-associated with the first bedside medical device 10, and both can obtain the desired target data. That is, the monitoring workstation 60 obtains the target data of the first bedside medical device 10 to which the pre-associated monitored patient belongs, which is also to obtain the target data of the pre-associated first bedside medical device 10.

[0051] In terms of location distribution, the monitoring workstation 60 can be a computer set up at the nurse's station, or a television, monitor, computer, etc. set up in locations such as corridors. It is mainly used to classify and display the target data of multiple patients under its monitoring. The first bedside medical device 10 of a patient can take the nearest monitoring workstation 60 in the vicinity as its associated monitoring workstation 60. For example, the bed number of the first bedside medical device 10 is bound to the patient, and the location of the monitoring workstations 60 in the department is usually fixed. Therefore, the first bedside medical device 10 of the patient only needs to find the nearest monitoring workstation 60 and associate it according to its own bed number and the device identifiers of each monitoring workstation 60. Of course, it can also be led by the monitoring workstation 60 to associate. That is, the monitoring workstation 60 finds the first bedside medical device 10 of the nearest one or more patients according to the bed numbers of each first bedside medical device 10 and associates them. There are many departments in the hospital, so the number of monitoring workstations 60 is relatively large. The monitoring workstation 60 can be a traditional central monitoring station. After summarizing the target data of each patient's first bedside medical device 10 in the department, it can classify and summarize the display of its target data according to the patient (or according to the bed), and can also manage the target data, manage and set the first bedside medical device 10, and manage the personal information of the patient, etc. The monitoring workstation can also have no management and operation functions, and is only used to receive the target data and classify and display the target data of each monitored patient according to the patient. For example, the television or monitor set up in the corridor outside the ward is such a monitoring workstation 60, which is responsible for displaying the target data of the patients in one or more wards, facilitating the medical staff to centrally view the data of multiple patients.

[0052] The monitoring workstation 60 is specifically used to determine whether the communication connection status between itself and the server 50 has changed; if the communication connection status between itself and the server 50 changes from abnormal to normal, it works in the first working mode: communicates with the server 50, obtains in real time the target data of the monitored patients associated in advance from the server 50, and presents the target data of the monitored patients classified by patient; if the communication connection status between itself and the server 50 changes from normal to abnormal, it works in the second working mode: communicates with the first bedside medical device 10 to which the monitored patient belongs, obtains in real time the target data generated during the operation of the first bedside medical device 10 from the first bedside medical device 10, and presents the target data of the monitored patients classified by patient. In this way, it not only meets the requirement that the hospital data is mainly stored and managed centrally by the server, but also ensures that after the connection with the server is abnormal, the monitoring workstation can still obtain the target data of the patient in real time for monitoring and presentation, improving the safety of patient monitoring.

[0053] As can be seen from the above, in this embodiment, the distributed medical monitoring method corresponding to the operation of the distributed medical monitoring system is mainly led by the monitoring workstation 60. For example, Figure 2 as shown, the method mainly includes the following steps:

[0054] Step 1, the monitoring workstation 60 determines whether the communication connection status between itself and the server 50 has changed. There are usually two types of communication connection status, one is normal connection, and the other is abnormal connection. For example, if the monitoring workstation 60 and the server 50 do not establish a connection, the connection is interrupted, etc., all belong to abnormal connection. Faults in the hospital backbone network, faults in the server 50, etc. will all cause the connection between the monitoring workstation 60 and the server 50 to be interrupted (abnormal connection). Of course, the connection between each first bedside medical device 10 and the server 50 will also be interrupted.

[0055] For example, Figure 3 as shown, the monitoring workstation 60 includes a processor 610, a communication module 620, and a human-computer interaction device 630.

[0056] The communication module 620 is used to communicate with the server 50, usually through the hospital network device 40 to communicate with the server 50. The communication module 620 can be connected to the hospital network device 40 in a wired or wireless manner. Of course, it can also communicate with the server 50 through the mobile network without passing through the network device 40. In this embodiment, for example, Figures 4 - 6 as shown, the communication modules 620 of each first bedside medical device 10 and each monitoring workstation 60 are all connected to the hospital switch 30. Among them, the monitoring workstation 60 and the first bedside medical device 10 of the patients (associated monitored patients) it monitors are connected to the same switch 30. That is, if the monitoring workstation 60 monitors three patients A, B, and C, then the monitoring workstation 60 and the first bedside medical devices 10 of these three patients are all connected to the same switch 30. The switch 30 is connected to the hospital network device 40, thereby realizing Figure 1 the network connection between various devices. The network device 40 is usually a network device of the hospital backbone network, and its quantity, distribution location, etc. are not limited.

[0057] The human-computer interaction device 630 is used for human-computer interaction, such as displaying visual information, and may include a display screen. Some monitoring workstations 60, such as computers, the human-computer interaction device 630 may also include an input device for receiving user input, such as using a mouse, keyboard, touch screen, various buttons, etc.

[0058] The processor 610 is used to determine whether the communication connection status between the communication module 620 and the server 50 has changed. For example, the processor 610 periodically sends verification messages (such as heartbeat packets) to the server 50 through the communication module 620. After receiving the verification message, the server 50 will feedback the received result to the monitoring workstation 60. If the processor 610 receives the feedback from the server 50 through the communication module 620, it is determined that the communication connection status between the communication module 620 and the server 50 is normal. If the processor 610 does not receive the feedback from the server 50 through the communication module 620, it is determined that the communication connection status between the communication module 620 and the server 50 is abnormal. The communication connection status is either normal (connected to the server) or abnormal (disconnected from the server). Therefore, by performing such an operation periodically, it is possible to basically know in real time whether the communication connection status has changed.

[0059] Step 2: If the communication connection status between the monitoring workstation 60 and the server 50 changes from abnormal to normal, it operates in the first working mode. For example, if the communication connection status between the communication module 620 and the server 50 changes from abnormal to normal, the processor 610 operates in the first working mode: the processor 610 communicates with the server 50 through the communication module 620, and obtains the target data of the monitored patients pre-associated from the server 50 in real time through the communication module 620, and presents the target data of these monitored patients classified by patient through the human-computer interaction device 630. Among them, presenting the target data may include displaying the target data on the display interface of the human-computer interaction device 630. For various alarm information (such as parameter and device alarm information) in the target data, it may also include emitting an alarm prompt sound corresponding to the alarm information. In this way, real-time monitoring, display, and alarm notification of patients are realized. It can be seen that in this embodiment, when the communication connection status between the monitoring workstation 60 and the server 50 is normal, the monitoring workstation 60 operates in the first working mode. The flow direction of the corresponding target data is as Figure 1 shown by the solid arrow. Under normal circumstances, the first bedside medical devices 10 in each department of the hospital can upload the target data to the server 50 in real time through the network, and the server 50 performs unified storage, management, and processing, etc. The monitoring workstation 60 can obtain the target data uploaded by the associated first bedside medical devices 10 from the server 50 in real time through the network, so that these target data can be displayed on the preset display interface, such as classified display by bed. Medical staff can see the physiological parameters, device operation parameters, and corresponding alarm information of patients through the monitoring workstations 60 set everywhere, which is very convenient.

[0060] Previously, the communication connection status between the communication module 620 and the server 50 was abnormal, and the processor 610 was operating in the second working mode. After the communication connection status becomes normal, it is necessary to switch to the first working mode. The switch can be automatically performed by the processor 610 or can be operated by the user. The following will be described separately.

[0061] After the processor 610 determines that the communication connection status between the communication module 620 and the server 50 has changed from abnormal to normal, such as when the communication connection changes from disconnected to reconnected, the processor 610 can automatically switch from the second working mode to the first working mode, so as to execute the functions corresponding to the first working mode. After the processor 610 switches the working mode, it can prompt the user through the human-computer interaction device 630 that the current has switched to the first working mode.

[0062] After the processor 610 determines that the communication connection status between the communication module 620 and the server 50 has changed from abnormal to normal, such as when the server 50 fails and then is repaired, the processor 610 can output a prompt message for switching to the first working mode through the human-computer interaction device 630, such as displaying the prompt message on the display interface of the human-computer interaction device 630. After seeing the prompt message, the medical staff can operate the human-computer interaction device 630 to issue an instruction for switching to the first working mode. The processor 610 receives the instruction for switching to the first working mode through the human-computer interaction device 630 and, in response to the instruction, switches from the second working mode to the first working mode.

[0063] After the processor 610 determines that the communication connection status between the communication module 620 and the server 50 has changed from abnormal to normal, such as when the hospital backbone network is paralyzed and then repaired, the medical staff can operate the human-computer interaction device 630 to issue an instruction for switching to the first working mode. The processor 610 receives the instruction for switching to the first working mode through the human-computer interaction device 630 and, in response to the instruction, switches from the second working mode to the first working mode. Of course, in some embodiments, the medical staff can issue an instruction for switching to the first working mode without being restricted by the communication connection status and can issue the instruction at any time.

[0064] Step 3: If the communication connection status between the monitoring workstation 60 and the server 50 changes from normal to abnormal, it works in the second working mode. For example, if the communication connection status between the communication module 620 and the server 50 changes from normal to abnormal, the processor 610 works in the second working mode: the processor 610 is communicatively connected to the first bedside medical device 10 to which the monitored patient belongs through the communication module 620, and obtains in real time the target data generated during the operation of these first bedside medical devices 10 through the communication module 620, and presents the target data of these monitored patients classified by patient through the human-computer interaction device 630. It can be seen that in this embodiment, when the communication connection status between the monitoring workstation 60 and the server 50 is abnormal, that is, when the monitoring workstation 60 cannot communicate with the server 50, the monitoring workstation 60 works in the second working mode, and the flow direction of the corresponding target data is as Figure 1 shown by the dotted arrow. When the communication connection status changes from normal to abnormal, such as network failure, server failure, etc., the monitoring workstation 60 can no longer obtain the target data of the patient from the server 50, so it turns to directly obtain the target data from the first bedside medical device 10 of the patient, and still can achieve real-time monitoring.

[0065] Similarly, the communication connection status between the communication module 620 and the server 50 was normal before, and the processor 610 worked in the first working mode. After the communication connection status becomes abnormal, it needs to be switched to the second working mode. The switch can be automatically performed by the processor 610 or can be operated by the user. The following will be described separately.

[0066] After the processor 610 determines that the communication connection status between the communication module 620 and the server 50 changes from normal to abnormal, such as the communication connection is suddenly disconnected, the processor 610 can automatically switch from the first working mode to the second working mode, so as to execute the functions corresponding to the second working mode. After the processor 610 switches the working mode, it can prompt the user through the human-computer interaction device 630 that it has been switched to the second working mode.

[0067] After the processor 610 determines that the communication connection status between the communication module 620 and the server 50 changes from normal to abnormal, such as the server 50 fails, the processor 610 can output a prompt message to switch to the second working mode through the human-computer interaction device 630, such as displaying the prompt message on the display interface of the human-computer interaction device 630. After the medical staff sees the prompt message, they can operate the human-computer interaction device 630 to issue an instruction to switch to the second working mode. The processor 610 receives the instruction to switch to the second working mode through the human-computer interaction device 630, and in response to the instruction, switches from the first working mode to the second working mode.

[0068] After the processor 610 determines that the communication connection status between the communication module 620 and the server 50 changes from normal to abnormal, such as when the backbone network fails, medical staff can operate the human-computer interaction device 630 to issue an instruction to switch to the second working mode. The processor 610 receives the instruction to switch to the second working mode through the human-computer interaction device 630, and in response to this instruction, switches from the first working mode to the second working mode. Of course, in some embodiments, the instruction issued by the medical staff to switch to the second working mode can be unrestricted by the communication connection status and can be issued at any time.

[0069] Since the monitoring workstation 60 and its associated first bedside medical device 10 are connected to the same switch 30, neither a backbone network failure nor a server failure will affect the switch 30. Therefore, the monitoring workstation 60 can quickly obtain target data from its associated first bedside medical device 10.

[0070] Due to changes in the patient's condition, the quantity and type of the patient's first bedside medical device 10 will change continuously, that is, the patient's first bedside medical device 10 will increase or decrease, and new patients will be associated with the monitoring workstation 60, while existing patients will withdraw from the association with the monitoring workstation 60. Therefore, the monitoring workstation 60 needs to identify each first bedside medical device 10 in order to distinguish which are the first bedside medical devices 10 of the associated patients. The following are several ways for the monitoring workstation 60 to identify the first bedside medical device 10.

[0071] Each first bedside medical device 10 can periodically send (such as by multicast or broadcast) its own device discovery packet. After receiving the device discovery packet, the monitoring workstation 60 can know that such a first bedside medical device 10 is working. The device discovery packet can include the device identifier (such as number or ID, etc.) of the first bedside medical device 10, and can also include the patient information of its affiliated patient (such as the unique number of the patient, etc.), so that the first bedside medical device 10 and its affiliated patient can be known, and it can be determined whether it belongs to a pre-associated patient.

[0072] The monitoring workstation 60 can also periodically inquire (such as by multicast or broadcast inquiry). After each first bedside medical device 10 receives the inquiry, it responds in a unicast, multicast or broadcast manner (such as by sending back a device discovery packet). The monitoring workstation 60 can also receive the device discovery packets of each bedside medical device and thus know its affiliated patient.

[0073] Of course, when the communication connection between the monitoring workstation 60 and the server 50 is normal, the device discovery packets sent by the first bedside medical device 10 can be forwarded by the server 50 to the monitoring workstation 60, and the monitoring workstation 60 caches them after receiving them.

[0074] In the above manner, the monitoring workstation 60 can obtain the device discovery packets of each first bedside medical device 10. After the communication connection status between the monitoring workstation 60 and the server 50 changes from normal to abnormal, the processor 610 can, according to the previously received device discovery packets, establish a direct network connection with the first bedside medical device 10 to which the monitored patient belongs through the communication module 620, temporarily replacing the server 50 to ensure that the real-time display or alarm presentation on the monitoring workstation 60 will not be interrupted due to reasons such as server anomalies, data center paralysis, or core network attacks.

[0075] The above step 1 can be carried out in real time, that is, the processor 610 can judge in real time whether the communication connection status between the communication module 620 and the server 50 has changed. In this way, once the server 50 becomes available again, the processor 610 can control the monitoring workstation 60 to resume the normal working mode (the first working mode). After resuming the normal working mode, each bedside medical device 10 and the monitoring workstation 60 are directly connected to the server 50. For details, see step 2 above and will not be elaborated here.

[0076] In summary, for the distributed medical monitoring system provided in the first embodiment, each medical device in the hospital uses the connected switch and hospital network equipment to directly send its own data to the medical device data processing server in the hospital data center for centralized processing and storage. If the hospital backbone network or the device data processing server fails, resulting in the interruption of the connection between the medical device and the server, then the local monitoring workstation placed on the department nurse station will also lose the connection with the server. The monitoring workstation will automatically detect this abnormal state and provide users with automatic and manual solutions to support switching the working mode of the monitoring workstation to directly connect to the bedside device to obtain the target data. When the hospital network or the device data processing server returns to normal, the monitoring workstation will automatically detect this state and provide users with automatic and manual solutions to support switching the workstation back to the original working mode. In this way, in the case of using the server to uniformly store and process the data of each medical device, it is ensured that the monitoring workstation can still obtain the target data to monitor the patient when the server fails, improving the monitoring safety.

[0077] Embodiment 2. In this embodiment, the distributed medical monitoring system is as Figure 6 and 7 shown, including: a server 50, one or more first bedside medical devices 10, and one or more monitoring workstations 60 communicatively connected to the server 50.

[0078] The first bedside medical device 10 is used to communicate with the server 50, and is also used to communicate with the monitoring workstation 60 pre-associated with the patient being monitored, and transmits the target data generated during the work to the server 50 and the pre-associated monitoring workstation 60 in real time. It can be seen that the first bedside medical device 10 in this embodiment supports sending the target data to multiple destinations at the same time, one of which is the monitoring workstation 60 associated with it (such as the monitoring workstation 60 near the first bedside medical device 10), which is used for real-time display and alarm presentation; the other destination is the server, which is used for data processing and data storage. In the first embodiment, the first bedside medical device 10 will only transmit its own target data to the associated monitoring workstation 60 when the communication connection state between the monitoring workstation 60 and the server 50 is abnormal, while the second embodiment transmits the target data generated during the work to the server 50 and the pre-associated monitoring workstation 60 at the same time regardless of the working mode or the communication connection state. In this way, regardless of the connection state between the monitoring workstation 60 and the server, the monitoring workstation 60 has a way to obtain the target data.

[0079] The server 50 is used to receive and store the target data sent in real time by each first bedside medical device 10, and transmit the target data of the monitored patient pre-associated with the monitoring workstation 60 to the monitoring workstation 60. The first bedside medical device 10 uploads the target data to the server 50 through the network device 40, and the server 50 transmits the target data to the pre-associated monitoring workstation 60 through the network device 40. The specific process is the same as the above-mentioned embodiment 1, and will not be repeated here.

[0080] The monitoring workstation 60 is used to receive the target data of the monitored patient transmitted in real time by the server and / or the first bedside medical device 10 and pre-associated, and present the target data of the monitored patient by patient classification. That is, the monitoring workstation 60 can receive and display the target data sent by the server in real time, and can also receive and display the target data sent by the first bedside medical device 10 in real time. Considering that the server may have a large delay, the monitoring workstation 60 usually placed in the department hopes to have a smaller data delay. Therefore, the monitoring workstation 60 uses the real-time target data directly obtained from each first bedside medical device 10 for display and alarm presentation to reduce the impact of network delay on real-time alarms.

[0081] The system provided in this embodiment works as follows: Figure 8 As shown, the following steps are included:

[0082] Step 1': One or more first bedside medical devices 10 are communicatively connected to a server 50 and also to a monitoring workstation 60 pre-associated with the monitored patient of the first bedside medical device 10 (the patient to whom the first bedside medical device 10 belongs), and transmit the target data generated during operation to the server 50 and the pre-associated monitoring workstation 60 in real time.

[0083] Step 2': The server 50 receives and stores the target data sent in real time by each first bedside medical device 10, and transmits the target data of the monitored patient pre-associated with the monitoring workstation 60 to the monitoring workstation 60 in real time.

[0084] Step 3': One or more monitoring workstations 60 receive the target data of the pre-associated monitored patients transmitted in real time by the server 50 and / or the first bedside medical devices 10, and present the target data of the monitored patients classified by patient. The monitoring workstation 60 presents the target data of the monitored patients classified by patient in the same specific manner as in Embodiment 1, which will not be elaborated here.

[0085] Whether it is Embodiment 1 or 2, as Figure 1 shown, the distributed medical monitoring system may further include a second bedside medical device 20. The second bedside medical device 20 may be unable to connect to the server 50 due to reasons such as protocols or power consumption, and thus cannot directly transmit the target data it generates to the server 50. The second bedside medical device 20 can be communicatively connected to the monitoring workstation 60 and transmit the target data generated during operation to the monitoring workstation 60. Then, the monitoring workstation 60 processes the target data transmitted by the second bedside medical device 20 and transmits the processed target data to the server 50. For example, the monitoring workstation 60 performs protocol conversion or data caching on the target data and transmits the target data after protocol conversion or data caching to the server 50. It is equivalent to the monitoring workstation 60 playing a role of data transfer. In this way, the system can basically add all the medical devices in the hospital to the network with the server, realizing data storage and remote processing.

[0086] Whether it is Embodiment 1 or 2, since the data of the in-hospital bedside medical devices (the first and second bedside medical devices) are stored and backed up by the server 50, each monitoring workstation 60 does not even need to store data. In other words, the monitoring workstation 60 can use devices without storage functions, such as monitors and televisions. There are usually televisions inside and outside the ward, so they can be utilized as the monitoring workstation 60.

[0087] The work of processing the target data can also be handed over to the powerful server 50. For example, the server 50 can summarize and organize the historical data of patients. Specifically, when medical staff want to view the historical data of a certain patient, they can send an instruction to review the historical data of the target patient through the human-computer interaction device 630 of the monitoring workstation 60. The processor 610 of the monitoring workstation 60 receives the instruction to review the historical data of the target patient through the human-computer interaction device 630. In response to this instruction, a review request is sent to the server 50 through the communication module 620. The server 50 receives the review request sent by the monitoring workstation 60. In response to this review request, the target data of the target patient within a preset time period is subjected to a first processing, and the data after the first processing is fed back to the monitoring workstation 60. The preset time period can be set as needed, such as one day, one week, one month, etc. Among them, the first processing may include the merging of the same physiological parameter data. For example, different bedside medical devices of a patient may all detect the same physiological parameter. Specifically, the first processing may include the merging of the data of the same physiological parameter detected by different bedside medical devices of the target patient within the same time period. The first processing may also include the classification of the target data. For example, the data related to physiological parameters is classified into one category, and the data related to device operation is classified into one category; or the display priority of the target data is adjusted according to the different diseases of the patient for classification, etc. The first processing may also include the statistics of the target data, such as calculating various statistical indicators of physiological parameters and / or device operation parameters, such as mean, median, maximum, minimum, variance, standard deviation, etc., such as counting the frequency, number of times, time distribution, severity distribution, etc. of parameter alarm information and / or device alarm information. Bedside medical devices usually work continuously (such as continuously detecting the physiological parameters of patients) to obtain target data, and patients may also use some non-continuously used diagnostic measurement devices, such as POCT (point-of-care testing) devices, ultrasonic measurement devices, non-invasive blood pressure measurement devices, infrared body temperature measurement devices, etc. These diagnostic measurement devices are not continuously monitored, but after use, they will still send the target data obtained by detecting patients to the server for storage. Therefore, the server can fuse this part of the data with the data of the bedside medical devices. Therefore, the first processing may also include the fusion of the target data of the bedside medical devices and the non-continuously used diagnostic measurement devices of the same patient, such as aligning the target data of these devices in time, so that after the monitoring workstation 60 receives the time-aligned data, it can display these data on the same time axis. Through such first processing, the breadth of patient data processing is improved, the data of all devices can be aligned, the clinical efficiency can be improved, and errors can be reduced.The first processing performed by the server can also improve the quality of patient data. For example, the first processing may further include running a preset signal quality analysis algorithm to process the target data of the patient, and marking out the data affected by interference (such as the instability of the electrocardiogram signal caused by patient movement). In this way, after the subsequent monitoring workstation 60 receives the data fed back by the server and displays it, the user can see the marked data affected by interference. When viewing the alarms that occurred in the past period of time, according to the needs of the condition, some low-quality historical data can be excluded, improving work efficiency. The monitoring workstation 60 receives and displays the data fed back by the server 50 based on the review request. It can be seen that the above-mentioned first processing is usually impossible for the workstation to achieve. Let the server 50 perform complex arithmetic processing on the data generated by the medical device like this, giving full play to the advantages of the server 50 itself, making the data displayed by the monitoring workstation 60 more comprehensive than that displayed by the traditional central monitoring station, and also reducing the requirements for the hardware of the monitoring workstation 60.

[0088] Similarly, the task of generating reports by the workstation traditionally can also be handed over to the server 50. When medical staff wants to obtain a report of a certain patient, they can send an instruction for obtaining the report of the target patient through the human-computer interaction device 630 of the monitoring workstation 60. The processor 610 of the monitoring workstation 60 receives the instruction for obtaining the report of the target patient through the human-computer interaction device 630, and in response to this instruction, sends a report acquisition request to the server 50. The server 50 receives the report acquisition request sent by the monitoring workstation 60, and in response to this request, processes the target data of the target patient in a preset manner to obtain a report. For example, a report is generated based on the target data generated by each bedside medical device of the target patient, and the report is fed back to the monitoring workstation 60. The monitoring workstation 60 receives the report fed back by the server 50 based on the report acquisition request, can display the report on the display interface, and can also print the report through the connected printer, which is very convenient.

[0089] When the communication between the monitoring workstation 60 and the server 50 is abnormal, it usually means that the bedside medical device cannot upload its target data to the server 50. Therefore, the monitoring workstation 60 can also cache the target data obtained from the first bedside medical device 10 during the period when the communication connection state between itself and the server 50 is abnormal; after the communication connection state between itself and the server 50 changes from abnormal to normal, the cached target data is transmitted to the server 50. In this way, it is ensured that the data stored in the server 50 will not be missed. Of course, this work can also be completed by the first bedside medical device 10. For example, the first bedside medical device 10 can cache the target data generated during work during the period when the communication connection state between itself and the server 50 is abnormal; after the communication connection state between itself and the server 50 changes from abnormal to normal, the cached target data is transmitted to the server 50.

[0090] In addition to being displayed on the associated monitoring workstation 60, the target data of the patient can also be accessed by other devices with relevant permissions, facilitating inquiries by attending physicians and the like. For example Figures 4 - 6 As shown, the distributed medical monitoring system further includes one or more browsing terminals 70. The browsing terminals 70 are used to communicate with the server 50, access the target data of the target patient stored in the server 50. Similar to the monitoring workstation 60, the first processed data and reports can also be obtained from the server 50 in the same manner. The specific process is the same as that of the monitoring workstation 60 (see the foregoing content) and will not be elaborated here. The browsing terminals 70 can be divided into in-hospital browsing terminals and out-of-hospital browsing terminals according to their locations. For example Figure 4 As shown, both can communicate with the server 50 through the hospital's network device 40, so as to obtain the above data from the server. Of course, the browsing terminals 70 can also be divided into in-hospital browsing terminals and out-of-hospital browsing terminals according to the different networks they are connected to. For example Figure 5 As shown, the browsing terminal connected to the server 50 through the in-hospital network device 40 is an in-hospital browsing terminal, and the browsing terminal connected to the server 50 through the external network is an out-of-hospital browsing terminal. In other words, the in-hospital and out-of-hospital browsing terminals can both obtain real-time target data and historical target data from the server 50, thereby realizing remote real-time monitoring and display, alarm notification, and historical review, etc. The above functions of the browsing terminal 70 are mainly to access and display the data of the server 50, so they can be implemented by a browsing software such as a browser. The browsing terminal 70 can also be a monitoring workstation. However, the target data accessed by such a monitoring workstation through the server is not the target data of its associated patient. In other words, the monitoring workstation can also access the target data of other patients in the server except for the patients associated with itself. Permissions can be set for such monitoring workstations, and only the monitoring workstations with permissions have such functions.

[0091] For example Figure 5 As shown, a firewall 80 can also be set between the network device 40 and the server 50 to improve data security.

[0092] As described in the background art, the existing monitoring central station integrates data storage and processing. If there is a problem with the monitoring central station, it will affect the monitoring of multiple patients. From the above content, it can be seen that in the distributed medical monitoring system provided by the present invention, the data of each medical device can be centrally stored and processed by the server. The medical device and the monitoring workstation, etc. do not need to perform data storage and data processing. The medical device is simply used to collect data, and the monitoring workstation is simply used to display data, reducing the importance of the department monitoring workstation. Moreover, considering the situation where the server and the backbone network fail, data can also be displayed through the direct connection between the medical device and the monitoring workstation during a failure, so as not to affect patient monitoring and improve the safety of patient monitoring.
