Description

Technical Field

[0001] The present invention relates to a multi-device alarm processing method and a central display device. Background Art

[0002] Human physiological parameters can reflect a person's physical state. Therefore, the monitoring of patients is a very important link. In scenarios such as during surgery, after surgery, trauma care, coronary heart disease, critically ill patients, neonates, premature infants, hyperbaric oxygen chambers, and delivery rooms, patients need to be monitored. During the monitoring of some patients, devices such as monitors, ventilators, and infusion pumps are generally involved. In an intensive care unit, there may also be treatment devices such as hemodialysis machines. During the monitoring process of these devices, when it detects a change in the patient's physiological state and determines that this change requires an alarm, an alarm will be issued to prompt medical staff to handle it in a timely manner. For example, when it detects that the patient's heart rate is too high or too low, or the blood oxygen parameter is too low, no pulse is detected, or the respiratory rate is too high or too low, the device will issue an alarm. The situations that require an alarm may be caused by a change in the patient's own physiological state, or may be due to the technical principle of the device. For example, the lead detachment caused by replacing the ECG electrode patch, and the search for pulse and no pulse caused by poor contact of the blood oxygen probe. These alarms - physiological alarms and technical alarms will be reported in the order of occurrence time. If a large number of alarms occur in a short period of time, it will cause trouble to medical staff and they cannot quickly distinguish in real time the alarms that may pose a life threat to the patient. For example, during a period of time, the patient's physiological state changes, causing the heart rate and respiratory rate to fluctuate above and below the heart rate alarm threshold and the respiratory rate alarm threshold. At the same time, there are also many device operations during this period. Taken together, a large number of over-limit alarms of heart rate and respiratory rate, as well as a large number of device technical alarms are generated during this period.

[0064] 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 are labeled with 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 to avoid overwhelming the core part of the present application with 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 descriptions in the specification and the general technical knowledge in the art.

[0065] 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.

[0066] 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 meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0067] The devices mentioned in the present invention for monitoring and / or treating patients typically refer to devices that can at least measure the physiological parameters of patients. These devices can usually give an alarm based on the obtained physiological parameters of the patients. For example, the obtained physiological parameters of the patients are compared with known set ranges or values, and if they are not within the normal range, an alarm is issued. These devices can be, for example, monitors, ventilators, anesthesia machines, infusion pumps, injection pumps, and hemodialysis machines, etc.

[0068] Figure 1This is an example of a monitor. In some embodiments, the monitor may have an independent housing, and a sensor interface area may be provided on the housing panel. The sensor interface area may integrate multiple sensor interfaces for connecting to various external physiological parameter sensor accessories 11. The housing panel may also include one or more of a small IXD display area, a display 23, an input interface circuit 22, and an alarm circuit 20 (such as an LED alarm area). In some embodiments, the monitor also has an external communication interface 19 and a power interface 16 for communicating with a host and obtaining power. In some embodiments, the monitor may also support an externally pluggable parameter module. A pluggable monitor can be formed by inserting the parameter module. As a part of the monitor, it can also be connected to the host through a cable, and the externally plugged parameter module serves as an external accessory of the monitor. The relevant circuits of the monitor can be placed inside the housing and may include one or more signal acquisition circuits 12 corresponding to physiological parameters and a front-end signal processing circuit 13. The signal acquisition circuit 12 can be selected from an electrocardiogram circuit, a respiration circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, etc. These signal acquisition circuits 12 are respectively electrically connected to the corresponding sensor interfaces for electrically connecting to the sensor accessories 11 corresponding to different physiological parameters. Their output ends are coupled to the front-end signal processing circuit 13. The communication port of the front-end signal processing circuit 13 is coupled to the processor 24, and the processor 24 is electrically connected to the external communication interface 19 and the power interface 16. The sensor accessories 11 and signal acquisition circuits 12 corresponding to various physiological parameters can adopt general circuits in the prior art. The front-end signal processing circuit 13 completes the sampling and analog-to-digital conversion of the output signals of the signal acquisition circuit 12 and outputs control signals to control the measurement process of physiological signals. These parameters include but are not limited to: electrocardiogram, respiration, body temperature, blood oxygen, non-invasive blood pressure, and invasive blood pressure parameters. The front-end signal processing circuit 13 can be implemented using a single-chip microcomputer or other semiconductor devices. For example, the LPC2136 of Philips or the mixed-signal single-chip microcomputer such as ADuC7021 of ADI can be selected, or it can also be implemented using an ASIC or an FPGA. The front-end signal processing circuit 13 can be powered by an isolated power supply. After the sampled data is simply processed and packed, it is sent to the processor 24 through an isolated communication interface. For example, the front-end signal processing circuit 13 can be coupled to the processor 24 through an isolated power interface 14 and a communication interface 15. The reason for powering the front-end signal processing circuit 13 by an isolated power supply is that the DC / DC power supply isolated by a transformer plays a role in isolating the patient from the power supply device. The main purposes are: (1) Isolate the patient. By the isolation transformer, the application part is floating-grounded to make the patient leakage current small enough; (2) Prevent the voltage or energy during defibrillation or electrosurgical applications from affecting the boards and devices of the intermediate circuits such as the main control board (ensured by creepage distance and clearance). Of course, the front-end signal processing circuit 13 can also be directly connected to the processor 24 through a cable.The processor 24 is used to complete the calculation of physiological parameters, and send the calculation results and waveforms of the parameters to the host (such as a host with a display, a PC, a central display device, etc.) through the external communication interface 19. Among them, the processor 24 can be directly connected to the external communication interface 19 through a cable for communication, and directly connected to the power interface 16 through a cable for power supply. The monitor can also include a power supply and battery management circuit 17. The power supply and battery management circuit 117 takes power from the host through the power interface 16, and supplies it to the processor 124 after processing, such as rectification and filtering, etc. The power supply and battery management circuit 17 can also monitor, manage and provide power protection for the power obtained from the host through the power interface 16. The external communication interface 19 can be one or a combination of local area network interfaces composed of Ethernet, Token Ring, Token Bus, and Fiber Distributed Data Interface (FDDI) which is the backbone network of these three networks, and can also be one or a combination of wireless interfaces such as infrared, Bluetooth, wifi, WMTS communication, etc., or can also be one or a combination of wired data connection interfaces such as RS232, USB, etc. The external communication interface 19 can also be a combination of one or two of a wireless data transmission interface and a wired data transmission interface. The host can be the host of the monitor or any computer device such as a computer. By installing the matching software, a monitoring system can be formed. The host can also be a communication device, such as a mobile phone. The monitor sends data to the mobile phone that supports Bluetooth communication through the Bluetooth interface to achieve remote data transmission. After the processor 24 completes the calculation of physiological parameters, it can also judge whether the physiological parameters are abnormal. If abnormal, an alarm can be given through the alarm circuit 20. The memory 18 can store the intermediate and final data of the monitor, as well as store program instructions or codes to be executed by the processor 24, etc. If the monitor has the function of blood pressure measurement, it can also include a pump valve drive circuit 21. The pump valve drive circuit 21 is used to perform inflation or deflation operations under the control of the processor 24.

[0069] The monitor can monitor the physiological parameters of patients, providing a good way for medical staff to comprehensively, intuitively and timely grasp the patient's condition. Generally, monitors are divided into two types: bedside monitors and transport monitors. The bedside monitor is an instrument set beside the hospital bed and connected to the patient, which can continuously monitor various physiological parameters or certain states of the patient, display alarms or record them. In actual situations, during the patient's hospitalization, etc., as the condition changes, the patient will be transferred between different hospital beds in the same department, or may need to go out for examinations, or may be transferred to different departments. During the process of being transferred from one location to another, the patient is monitored by a transport monitor instead of the bedside monitor.

[0070] Please refer toFigure 2 , in order to facilitate medical staff to remotely understand the physiological conditions of patients, a central display device can be introduced. In some embodiments, the central display device can save the data of monitors and other devices mentioned in the present invention for monitoring and / or treating patients, such as ventilators, anesthetic machines, infusion pumps, injection pumps, and hemodialysis machines, etc., centrally manage patient information and nursing information, and facilitate the preservation of historical data and the collation of alarm information. Specifically, the central display device can establish connections with one or more devices mentioned in the present invention for monitoring and / or treating patients, and each device for monitoring and / or treating patients can generate alarm information and transmit the alarm information to the central display device. The connection method between the central display device and these devices can be wired or wireless.

[0071] Please refer to Figure 3 , the central display device of the present invention can process the alarm information generated by these devices for monitoring and / or treating patients - namely, devices 1, 2, 3 to device N in the figure, optimize these alarm information, so that when a large number of alarm information appears within a period of time, especially a short period of time, medical staff can quickly locate some alarm information worthy of attention. Of course, it can be understood that Figure 3 in these devices 1, 2, 3 to device N are all used for monitoring and / or treating the same patient, that is Figure 3 the alarm information generated by these devices 1, 2, 3 to device N in is for the same object, the same patient. Please refer to Figure 4 , the central display device in some embodiments includes a display 30, a processor 32, and a memory 34. The memory 34 stores a number of program instructions 36, or rather, the central display device further includes a number of program instructions 36 stored in the memory 34, and these program instructions 36 can be called by the processor 32 to execute corresponding steps and complete corresponding functions, which will be specifically described below.

[0072] Please refer to Figure 5 , Figure 6 and Figure 7 , in some embodiments, the processor 32 can call the above-mentioned number of program instructions 36 to execute the following steps:

[0073] Step 100: Real-time obtain a plurality of alarm information respectively generated by a plurality of devices, or obtain a plurality of alarm information generated by these plurality of devices within a preset time period.

[0074] It can be understood that the plurality of devices here refer to the devices that are connected to the central display device and can generate alarm information and transmit the alarm information to the central display device, and these devices are for monitoring and / or treating the same patient.

[0075] Step 120: Determine the correlation between multiple devices in terms of the alarm cause. That is, when the central display receives alarm messages sent by multiple devices, determine the correlation between these multiple devices in terms of the alarm cause for subsequent optimization.

[0076] The existence of a correlation between any two devices in terms of the alarm cause means that the alarm message generated by one device is caused by the other device. For example, the alarm message generated by one device is caused by a change in the set parameters of the other device - this change in the set parameters can be caused by the device itself adapting and adjusting, or by the user actively operating the device. It can be seen that this correlation reflects a causal relationship of the alarm cause.

[0077] For example, after the ventilator resets the respiratory rate, it may cause a respiratory alarm on the monitor - of course, the ventilator itself may also give a respiratory alarm. In this case, the present invention believes that there is a correlation between the respiratory rate setting of the ventilator and the respiratory alarm on the monitor in terms of the alarm cause, and the respiratory alarm generated by the monitor is caused by the change in the set parameter of the respiratory rate of the ventilator.

[0078] For another example, when the ventilator sets a relatively low respiratory rate, it may cause an alarm for too low blood oxygen level on the monitor - of course, the ventilator itself may also give an alarm for too low blood oxygen level. Therefore, the present invention believes that there is a correlation between the too low respiratory rate setting of the ventilator and the alarm for too low blood oxygen level on the monitor in terms of the alarm cause, and the alarm for too low blood oxygen level generated by the monitor is caused by the change in the set parameter of the too low respiratory rate of the ventilator.

[0079] For another example, when parameters such as the dialysis volume of the hemodialysis machine change, resulting in a large amount of fluid being input to the patient, this may cause a body temperature alarm on the monitor and may also cause an alarm for too low blood oxygen level on the monitor - of course, the hemodialysis machine itself may also give a body temperature alarm and / or an alarm for too low blood oxygen level. Then it is considered that there is a correlation between the increase in the dialysis volume of the hemodialysis machine and the body temperature alarm on the monitor and the alarm for too low blood oxygen level on the monitor in terms of the alarm cause, and the body temperature alarm on the monitor and the alarm for too low blood oxygen level on the monitor are caused by the increase in the set parameter of the dialysis volume of the hemodialysis machine.

[0080] To determine whether there is a correlation in the alarm causes between two devices, it can be a real-time logical judgment by the processor 32, or the processor 32 can query a predefined correlation to determine. For example, several correlations are predefined. For example, Correlation 1: There is a correlation in the alarm cause between the respiratory rate setting of the ventilator and the respiratory alarm of the monitor; Correlation 2: There is a correlation in the alarm cause between the too low respiratory rate setting of the ventilator and the alarm of the monitor for too low blood oxygen value; Correlation 3: There is a correlation in the alarm cause between the increased dialysis volume of the hemodialysis machine and the body temperature alarm of the monitor; Correlation 4: There is a correlation in the alarm cause between the increased dialysis volume of the hemodialysis machine and the alarm of the monitor for too low blood oxygen value; and so on.

[0081] Step 140: When there is a correlation in the alarm cause between at least two different devices, optimize the alarm information generated by the at least two different devices. In some specific embodiments, Step 140 determines the backend device among the at least two different devices that have a correlation in the alarm cause and that is at the backend of the alarm transmission chain corresponding to the generated alarm information; and then reduces the initial alarm level of the alarm information generated by the backend device.

[0082] For example, after the ventilator resets the respiratory rate, it may cause the respiratory alarm of the monitor - of course, the ventilator itself may also give a respiratory alarm. In this case, the present invention believes that there is a correlation in the alarm cause between the respiratory rate setting of the ventilator and the respiratory alarm of the monitor, and the respiratory alarm generated by the monitor is caused by the change in the setting parameter such as the respiratory rate of the ventilator; from the perspective of the alarm transmission chain corresponding to the generated alarm information, the ventilator is at the front end and the monitor is at the backend. Therefore, reduce the initial alarm level of the respiratory alarm generated by the backend device, that is, the monitor - for example, assume that the initial alarm level of this respiratory alarm generated by the monitor is medium level, then now reduce its alarm level to low level.

[0083] For another example, when the ventilator sets a relatively low respiratory rate, it may cause the alarm of the monitor for too low blood oxygen value - of course, the ventilator itself may also give an alarm for too low blood oxygen value. Therefore, the present invention believes that there is a correlation in the alarm cause between the too low respiratory rate setting of the ventilator and the alarm of the monitor for too low blood oxygen value, and the alarm of the monitor for too low blood oxygen value is caused by the change in the setting parameter such as the too low respiratory rate setting of the ventilator; from the perspective of the alarm transmission chain corresponding to the generated alarm information, the ventilator is at the front end and the monitor is at the backend. Therefore, reduce the initial alarm level of the alarm of the monitor for too low blood oxygen value generated by the backend device - for example, assume that the initial alarm level of the alarm of the monitor for too low blood oxygen value generated currently is medium level, then now reduce its alarm level to low level.

[0084] For another example, if parameters such as the dialysis volume of a hemodialysis machine change, causing a large amount of fluid to be input into the patient, this may trigger a body temperature alarm on the monitor and may also trigger an alarm for too low blood oxygen level on the monitor - of course, the hemodialysis machine itself may also trigger a body temperature alarm and / or an alarm for too low blood oxygen level. In this case, it is considered that there is a correlation in the alarm causes between the increase in the dialysis volume of the hemodialysis machine and the body temperature alarm on the monitor and the alarm for too low blood oxygen level on the monitor. The body temperature alarm on the monitor and the alarm for too low blood oxygen level on the monitor are triggered by the increase in the set parameter of the dialysis volume of the hemodialysis machine. Looking at the alarm transmission chain corresponding to the alarm information for too low blood oxygen level generated, the hemodialysis machine is at the front end and the monitor is at the back end. Therefore, the initial alarm level of the alarm for too low blood oxygen level generated by the back-end device, i.e., the monitor, is reduced - for example, assuming that the initial alarm level of the alarm for too low blood oxygen level currently generated by the monitor is medium level, then now its alarm level is reduced to low level. Similarly, looking at the alarm transmission chain corresponding to the generated body temperature alarm, the hemodialysis machine is at the front end and the monitor is at the back end. Therefore, the initial alarm level of the body temperature alarm generated by the back-end device, i.e., the monitor, is reduced - for example, assuming that the initial alarm level of the body temperature alarm currently generated by the monitor is medium level, then now its alarm level is reduced to low level.

[0085] In some embodiments, the initial alarm level of each alarm information is related to its parameter alarm level, and the parameter alarm level is determined by the parameter value that triggers the alarm. For example, the lower the respiratory rate, the higher the parameter alarm level of the respiratory alarm it triggers, and correspondingly, the higher the corresponding initial alarm level.

[0086] It can be understood that step 150 optimizes each specific alarm information one by one. After the alarm information generated by any device is optimized, the initial alarm level of the same type of alarm information generated by that device later has nothing to do with the primary level of the alarm information that was optimized before. For example,

[0087] At the first moment, after the ventilator reset the respiratory rate, it caused a respiratory alarm on the monitor. Assuming that the initial alarm level of the respiratory alarm currently generated by the monitor is medium level, then after step 150 optimizes it, the alarm level of this respiratory alarm is reduced to low level; at the second moment later, the monitor issues another respiratory alarm, and the initial level of the respiratory alarm of the monitor at this moment has nothing to do with and is independent of the alarm level of the optimized-to-low-level respiratory alarm generated by the monitor at the first moment. The initial alarm level of the respiratory alarm generated by the monitor at the second moment is, for example, related to its parameter alarm level.

[0088] Step 160: Display the optimized alarm information. For example, the display 30 displays the optimized alarm information.

[0089] The specific display manner may be to display the alarm information and its optimized level. For example, for the respiration alarm of the current monitor, when its alarm level is medium and is optimized to low level, then display the respiration alarm of this monitor and its optimized level.

[0090] Step 180: Sort the obtained alarm information according to the alarm levels of the respective alarm information, and display the sorted alarm information. For example, the display 30 displays the sorted alarm information. It can be understood that sorting the respective alarm information in step 180 refers to sorting the alarm information that has been optimized.

[0091] The processor 32 of the central display device implements the multi-device alarm processing method by executing Figure 5 、 Figure 6 or Figure 7 's step process. The multi-device alarm processing method can be applied to real-time alarm scenarios. For example, when in step 100, multiple alarm information respectively generated by multiple devices are obtained in real time, and then the obtained alarm information is optimized and displayed through steps 120, 140, and 160; the multi-device alarm processing method can also be applied to alarm review scenarios. For example, when in step 100, multiple alarm information generated by multiple devices within a preset time period are obtained, and then these alarm information are optimized through steps 120 and 140, and then the alarm information is sorted and displayed through step 180.

[0092] Please refer to Figure 8 、 Figure 9 and Figure 10 In some embodiments, the processor 32 can call the above-mentioned several program instructions 36 and execute the following steps:

[0093] Step 200: Obtain in real time multiple alarm information respectively generated by multiple devices, or obtain multiple alarm information generated by these multiple devices within a preset time period.

[0094] It can be understood that the multiple devices here refer to devices that are connected to the central display device and can generate alarm information and transmit the alarm information to the central display device, and these devices monitor and / or treat the same patient.

[0095] Step 220: For the alarm information generated by any first device, determine whether the first alarm information generated by the first device is caused by a change in the setting parameters of any second device.

[0096] Understandably, the first device and the second device here are devices among the multiple devices mentioned in the above step 200. Moreover, the "first" and "second" of the first device and the second device here are only for facilitating the description of the technical solution. They are only used to distinguish the described objects and do not have any sequential or technical meaning. When appearing in the same statement, the first device and the second device are just two different devices. Additionally, the first alarm message generated by the first device here also refers to a specific alarm message among the alarm messages generated by the first device. Here, it is for the convenience of narration and distinction, following the naming method of the first alarm message. Therefore, whether the first alarm message generated by the first device in step 220 is caused by a change in the setting parameter of any second device actually means whether a specific alarm message generated by any one of the multiple devices in step 200 is caused by a change in the setting parameter of other devices among these multiple devices.

[0097] Step 220 can be implemented in various ways. For example, please refer to Figure 11 , in some embodiments, step 220 for determining whether the first alarm message generated by the first device is caused by a change in the setting parameter of any second device includes the following steps:

[0098] Step 221: Determine whether there is a corresponding alarm transfer chain for the first alarm message generated by the first device.

[0099] Step 223: If it exists, determine whether the first device is at the rear end of the alarm transfer chain.

[0100] Step 225: If it is, then determine whether the corresponding setting parameter of the device at the front end of the alarm transfer chain corresponding to the first alarm message has changed.

[0101] Step 227: If it has changed, then determine that the first alarm message generated by the first device is caused by a change in the parameter of the device at the front end of the alarm transfer chain corresponding to the first alarm message.

[0102] The alarm transfer chain reflects a kind of causality of the cause of the alarm message. It defines the devices at the front end and the rear end on this transfer chain. The front-end device and the rear-end device have a causal relationship of cause and effect. A change in the parameter of the front-end device can cause an alarm of the rear-end device.

[0103] For example, after the ventilator resets the respiratory rate, it may trigger a respiratory alarm on the monitor - of course, the ventilator itself may also issue a respiratory alarm. In this case, the present invention believes that there is a corresponding alarm transmission chain for the respiratory alarm generated by the monitor, and on this alarm transmission chain, the monitor is at the rear end of the alarm transmission chain, that is, the rear-end device, and the ventilator is at the front end of the alarm transmission chain, that is, the front-end device; the front-end device of the alarm transmission chain corresponding to the respiratory alarm of the monitor is the ventilator, and its corresponding setting parameter, that is, the respiratory rate, has changed. Then it is determined that the respiratory alarm of the monitor is caused by the parameter change of the front-end device of the alarm transmission chain corresponding to it, that is, the ventilator.

[0104] For another example, setting a lower respiratory rate on the ventilator may trigger an alarm for too low blood oxygen level on the monitor - of course, the ventilator itself may also issue an alarm for too low blood oxygen level. Therefore, the present invention believes that there is a corresponding alarm transmission chain for the alarm for too low blood oxygen level generated by the monitor, and on this alarm transmission chain, the monitor is at the rear end of the alarm transmission chain, that is, the rear-end device, and the ventilator is at the front end of the alarm transmission chain, that is, the front-end device; the front-end device of the alarm transmission chain corresponding to the alarm for too low blood oxygen level of the monitor is the ventilator, and its corresponding setting parameter, that is, the respiratory rate, has changed. Then it is determined that the alarm for too low blood oxygen level of the monitor is caused by the parameter change of the front-end device of the alarm transmission chain corresponding to it, that is, the ventilator.

[0105] For another example, changes in parameters such as the dialysis volume of the hemodialysis machine result in a large amount of fluid being input to the patient, which may trigger a body temperature alarm on the monitor and may also trigger an alarm for too low blood oxygen level on the monitor - of course, the hemodialysis machine itself may also issue a body temperature alarm and / or an alarm for too low blood oxygen level. Therefore, the present invention believes that there is a corresponding alarm transmission chain for the body temperature alarm generated by the monitor, and there is also a corresponding alarm transmission chain for the alarm for too low blood oxygen level generated by the monitor. In these two alarm transmission chains, the monitor is at the rear end of the alarm transmission chain, that is, the rear-end device, and the hemodialysis machine is at the front end of the alarm transmission chain, that is, the front-end device; the front-end device of the alarm transmission chain corresponding to the body temperature alarm of the monitor is the hemodialysis machine, and its corresponding setting parameter, such as the dialysis volume, has changed. Then it is determined that the alarm for too low blood oxygen level of the monitor is caused by the parameter change of the front-end device of the alarm transmission chain corresponding to it, that is, the hemodialysis machine; similarly, the front-end device of the alarm transmission chain corresponding to the alarm for too low blood oxygen level of the monitor is the hemodialysis machine, and its corresponding setting parameter, such as the dialysis volume, has changed. Then it is determined that the alarm for too low blood oxygen level of the monitor is caused by the parameter change of the front-end device of the alarm transmission chain corresponding to it, that is, the hemodialysis machine.

[0106] Determine whether there is a corresponding alarm transmission chain for the first alarm information generated by the first device. This can be a real-time logical judgment by the processor 32 or the processor 32 querying a pre-defined alarm transmission chain to determine. For example, several alarm transmission chains are pre-defined. For example, for the alarm transmission chain 1 corresponding to the respiratory alarm of the monitor: the ventilator is the front-end device and the monitor is the back-end device. A change in the respiratory rate of the ventilator can cause a respiratory alarm on the monitor; for the alarm transmission chain 2 corresponding to the alarm of the monitor with too low blood oxygen value: the ventilator is the front-end device and the monitor is the back-end device. Setting the respiratory rate of the ventilator too low can cause the alarm of the monitor with too low blood oxygen value; for the alarm transmission chain 3 corresponding to the body temperature alarm of the monitor: the hemodialysis machine is the front-end device and the monitor is the back-end device. An increase in the dialysis volume of the hemodialysis machine can cause the body temperature alarm of the monitor; for the alarm transmission chain 4 corresponding to the alarm of the monitor with too low blood oxygen value: the hemodialysis machine is the front-end device and the monitor is the back-end device. An increase in the dialysis volume of the hemodialysis machine can cause the alarm of the monitor with too low blood oxygen value; and so on.

[0107] Step 240: If so, lower the initial alarm level of the first alarm information generated by the first device.

[0108] The following are several examples for illustration.

[0109] For example, after the ventilator resets the respiratory rate, if it causes a respiratory alarm on the monitor, that is, the respiratory alarm generated by the monitor is caused by a change in the set parameter such as the respiratory rate of the ventilator. In this case, the monitor is the first device, the respiratory alarm generated by the monitor is the first alarm information, the ventilator is the second device, and the alarm level of the respiratory alarm generated by the monitor will be lowered. For example, if its initial alarm level is medium, then its alarm level can now be lowered to low.

[0110] Another example, if the ventilator sets a relatively low respiratory rate, causing an alarm of too low blood oxygen value on the monitor, that is, the alarm of too low blood oxygen value generated by the monitor is caused by a change in the set parameter such as the respiratory rate of the ventilator. In this case, the monitor is the first device, the alarm of too low blood oxygen value generated by the monitor is the first alarm information, the ventilator is the second device, and the alarm level of the respiratory alarm generated by the monitor will be lowered. For example, if its initial alarm level is medium, then its alarm level can now be lowered to low.

[0111] For another example, parameters such as the dialysis volume of a hemodialysis machine change, resulting in a large amount of fluid being input into the patient, thereby triggering a body temperature alarm of the monitor and an alarm for too low blood oxygen value of the monitor. In this case, two independent optimizations will be carried out. In one optimization, the monitor is the first device, the body temperature alarm generated by the monitor is the first alarm information, the hemodialysis machine is the second device, and the alarm level of the body temperature alarm generated by the monitor will be reduced. For example, if its initial alarm level is medium level, then now its alarm level can be reduced to low level. In another optimization, the alarm for too low blood oxygen value of the monitor is the first alarm information, and its alarm level will be reduced. For example, if its initial alarm level is medium level, then now its alarm level can be reduced to low level.

[0112] In some embodiments, the initial alarm level of each alarm information is related to its parameter alarm level, and the parameter alarm level is determined by the parameter value that triggers the alarm. For example, the lower the respiratory rate, the higher the parameter alarm level of the respiratory alarm it triggers, and correspondingly, the higher the corresponding initial alarm level.

[0113] Step 260: Display the first alarm information after reducing the initial alarm level. For example, the display 30 displays the first alarm information after reducing the initial alarm level.

[0114] The specific display method can be to display the alarm information and its reduced level. For example, for the current respiratory alarm of the monitor, after its alarm level is reduced from medium level to low level, the respiratory alarm of the monitor and its reduced level are displayed.

[0115] Step 280: Sort the obtained alarm information according to the alarm levels of each alarm information, and display the sorted alarm information. For example, the processor 32 sorts the obtained alarm information according to the alarm levels of each alarm information; the display 30 then displays the sorted alarm information.

[0116] The processor 32 of the central display device implements the multi-device alarm processing method by executing Figure 8 、 Figure 9 or Figure 10 's step process. The multi-device alarm processing method can be applied to real-time alarm scenarios. For example, when multiple alarm information respectively generated by multiple devices are obtained in real time in step 200, the obtained alarm information is processed and displayed through steps 220, 240, and 260; the multi-device alarm processing method can also be applied to alarm review scenarios. For example, when in step 200, multiple alarm information generated by multiple devices within a preset time period are obtained, these alarm information are processed through steps 220 and 240, and then the alarm information is sorted and displayed through step 1280.

[0117] In some embodiments, it may also be Figure 3 one of the devices 1, 2, 3 to N in [[ ]] (let's call it device A) to replace the central display device. Device A can be used to monitor and / or treat patients, and device A establishes a connection with other devices for monitoring and / or treating patients mentioned in the present invention.
