Description

Alarm processing method, central display device and monitoring or treating device

Technical Field

The invention relates to an alarm processing method, a central display device and a monitoring or treatment device.

Background

The physiological parameters of a person reflect the physical condition of the person, and therefore, the monitoring of a patient is an important link, and the patient needs to be monitored in the scenes such as operation, post-operation, trauma care, coronary heart disease, critical patients, neonates, premature babies, hyperbaric oxygen chambers, delivery rooms and the like. In some patient monitoring procedures, devices such as monitors, ventilators, and infusion pumps are typically involved, and therapeutic devices such as hemodialysis machines may be present in an intensive care unit. In the monitoring process, when the physiological state change of the patient is detected and the change is judged to need alarming, the equipment can give an alarm to prompt medical staff to deal with the change in time. For example, when the patient is detected to have too high or too low heart rate, or too low blood oxygen parameter, no pulse, too high or too low respiratory rate, the device will alarm. The condition that the alarm needs to be given may be caused by the change of the physiological state of the patient, or may be caused by the principle of the device technology, such as the lead falling caused by the replacement of the electrode plate of the electrocardiogram, the pulse searching and pulse absence caused by the poor contact of the blood oxygen probe, etc. The alarms, namely the physiological alarm and the technical alarm can be reported according to the occurrence time sequence, if a large amount of alarms occur in a short time, the alarms cause troubles for medical staff, and the alarms which can cause life danger of a patient cannot be rapidly distinguished in real time, for example, the change of the physiological state of the patient in a period of time causes the fluctuation of the heart rate and the respiration rate on the heart rate alarm threshold value and the respiration rate alarm threshold value, and a plurality of equipment operations exist in the period of time, so that the alarm of the overrun type of a large amount of heart rate and respiration rate and a large amount of equipment technical alarms are generated in the period of time in a comprehensive manner.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

Devices for monitoring and/or treating a patient as referred to in the present invention typically refer to devices that at least measure physiological parameters of the patient, which devices are generally capable of alerting based on the acquired physiological parameters of the patient, e.g. comparing the acquired physiological parameters of the patient with known set ranges or values and if not within normal ranges, alerting. These devices may be, for example, monitors, ventilators, anesthesia machines, infusion pumps, syringe pumps, hemodialysis machines, and the like.

Fig. 1 is an example of a monitor. In some embodiments, the monitor may have a separate housing, and the housing panel may have a sensor interface area, wherein the sensor interface area may integrate a plurality of sensor interfaces for connecting with the external physiological parameter sensor accessories 11. One or more of a small IXD display area, a display 23, input interface circuitry 22, and alarm circuitry 20 (e.g., an LED alarm area), etc., may also be included on the housing panel. In some embodiments, the monitor also has an external communication interface 19 and a power interface 16 for communicating with and powering a host computer or the like. In some embodiments, the monitor may further support an external parameter plug-in module, which may be formed by inserting the parameter plug-in module as a part of the monitor or connected to the host computer through a cable, and the external parameter plug-in module is used as an external accessory of the monitor. The related circuits of the monitor can be disposed in the housing, and can include a signal acquisition circuit 12 and a front-end signal processing circuit 13 corresponding to one or more physiological parameters, the signal acquisition circuit 12 can be selected from an electrocardiograph circuit, a respiration circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, and the like, these signal acquisition circuits 12 are respectively electrically connected with the corresponding sensor interfaces for electrically connecting to the sensor accessories 11 corresponding to different physiological parameters, the output end thereof is 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 with the external communication interface 19 and the power interface 16. The sensor accessory 11 and the signal acquisition circuit 12 corresponding to various physiological parameters can adopt a common circuit in the prior art, the front-end signal processing circuit 13 performs sampling and analog-to-digital conversion of the output signal of the signal acquisition circuit 12, and outputs a control signal to control the measurement process of the physiological signal, and the parameters include but are not limited to: electrocardio, respiration, body temperature, blood oxygen, noninvasive blood pressure and invasive blood pressure parameters. The front-end signal processing circuit 13 may be implemented by a single chip microcomputer or other semiconductor devices, for example, a mixed signal single chip microcomputer such as LPC2136 of philips corporation or adic 7021 of ADI, or an ASIC or FPGA. The front-end signal processing circuit 13 may be powered by an isolated power supply, and the sampled data is sent to the processor 24 through an isolated communication interface after being simply processed and packed, for example, the front-end signal processing circuit 13 may be coupled to the processor 24 through the isolated power supply interface 14 and the communication interface 15. The reason that the front-end signal processing circuit 13 is powered by the isolation power supply is that the DC/DC power supply isolated by the transformer plays a role in isolating the patient from the power supply equipment, and the main purpose is as follows: (1) isolating the patient, and floating the application part through an isolation transformer to ensure that the leakage current of the patient is small enough; (2) the voltage or energy when defibrillation or electrotome is applied is prevented from influencing board cards and devices of intermediate circuits such as a main control board and the like (guaranteed by creepage distance and electric clearance). Of course, the front-end signal processing circuit 13 may also be directly connected to the processor 24 through a cable. The processor 24 is used for completing the calculation of the physiological parameters and sending the calculation results of the parameters and the waveforms to a host (such as a host with a display, a PC, a central display device, etc.) through the external communication interface 19; wherein the processor 24 can be directly connected with the external communication interface 19 through a cable for communication and directly connected with the power interface 16 through a cable for power supply; the monitor may further include a power and battery management circuit 17, the power and battery management circuit 117 obtains power from the host through the power interface 16, and supplies the processed power to the processor 124, such as rectification and filtering; the power supply and battery management circuitry 17 may also monitor, manage and power protect the power drawn from the host through the power interface 16. The external communication interface 19 may be one or a combination of local area network interfaces formed by Ethernet (Ethernet), Token Ring (Token Ring), Token Bus (Token Bus) and Fiber Distributed Data Interface (FDDI) as a backbone network of these three networks, one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, or one or a combination of wired data connection interfaces such as RS232 and USB. The external communication interface 19 may be one or a combination of a wireless data transmission interface and a wired data transmission interface. The host computer can be any computer equipment of a host computer or a computer of the monitor, and the monitoring system can be formed by installing matched software. The host can also be communication equipment, such as a mobile phone, and the monitor sends data to the mobile phone supporting Bluetooth communication through the Bluetooth interface to realize remote transmission of the data. After the processor 24 completes the calculation of the physiological parameter, it can also determine whether the physiological parameter is abnormal, and if so, it can alarm through the alarm circuit 20. The memory 18 may store intermediate and final data for the monitor as well as program instructions or code for execution by the processor 24 or the like. If the monitor has a blood pressure measurement function, a pump valve driving circuit 21 may be further included, and the pump valve driving circuit 21 is used for performing inflation or deflation operations under the control of the processor 24.

The monitor can monitor the physiological parameters of the patient, and provides a good way for medical staff to comprehensively, intuitively and timely master the illness state of the patient. Generally, monitors are classified into two types, bedside monitors and transport monitors. The bedside monitor is arranged at the bedside of a patient and connected with the patient, and can continuously monitor various physiological parameters or certain states of the patient and display, alarm or record the physiological parameters or the certain states. In practical situations, during hospitalization, etc., a patient may be transferred between different beds in the same department as the condition of the patient changes, or may need to go out for examination, or may be transferred to different departments, and during the process of transferring from one location to another, the patient is monitored by the bedside monitor instead of the transfer monitor.

Referring to fig. 2, a central display device may be introduced to facilitate the medical staff to remotely know the physiological condition of the patient. In some embodiments, the central display device can store data of monitors and other devices for monitoring and/or treating patients, such as ventilators, anesthesia machines, infusion pumps, syringe pumps, hemodialysis machines, and the like, and centrally manage patient information and care information, thereby facilitating the storage of historical data and the arrangement of alarm information. In particular, the central display device may establish a connection with one or more devices for monitoring and/or treating patients as mentioned in the present invention, each device for monitoring and/or treating patients being able to generate and transmit alarm information to the central display device. The connection mode between the central display device and the devices can be wired connection or wireless connection.

Referring to fig. 3, the central display device of the present invention can process the alarm messages generated by the devices for monitoring and/or treating the patient, i.e. the device 1, the device 2, the device 3 to the device N in the figure, and optimize the alarm messages, so that when a large amount of alarm messages appear in a period of time, especially in a short time, the medical staff can quickly locate some alarm messages which are worth noticing. It is of course understood that these devices 1, 2, 3 to N in fig. 3 are all for monitoring and/or treating the same patient, i.e. the alarm information generated by these devices 1, 2, 3 to N in fig. 3 is for the same subject, the same patient. Referring to fig. 4, a central display device in some embodiments includes a display 30, a processor 32, and a memory 34. The memory 34 stores a plurality of program instructions 36, or the central display device further includes a plurality of program instructions 36 stored in the memory 34, the program instructions 36 being capable of being invoked by the processor 32 to perform corresponding steps to perform corresponding functions, as described in more detail below.

Referring to fig. 5 and 6, in some embodiments, the processor 32 can call the program instructions 36 to perform the following steps:

step 100: the method comprises the steps of acquiring a plurality of alarm messages generated by one or more devices respectively in real time, or acquiring a plurality of alarm messages generated by one or more devices within a preset time period.

It is understood that one or more devices herein refers to a device that establishes a connection with a central display device and is capable of generating and communicating alarm information to the central display device, and when multiple devices, these devices are monitoring and/or treating the same patient.

Step 120: the relevance between the plurality of pieces of alarm information acquired in step 100 above is determined.

Step 140: and performing combined alarm according to the relevance among the alarm information.

It can be seen that step 120 and step 140 both relate to the correlation between alarm information. In some embodiments, the alarm information triggered by the same original event, such as a change in setting parameters of the same device, a change in the same physiological state of the patient, and the like, is determined to be related.

Therefore, in some embodiments, the step 140 of performing a joint alarm according to the correlation between the plurality of alarm information may include: and carrying out combined alarm according to the alarm information of one device or a plurality of devices triggered by the same original event.

In some specific embodiments, the performing of the joint alarm according to the alarm information of one device or multiple devices triggered by the same original event may include, for example: and performing combined alarm according to alarm information of one device or a plurality of devices caused by the change of the setting parameters of the same device. The following description will be made by taking several examples.

For example, example 1: after the breathing machine is reset with a lower breathing rate, the breathing alarm of the monitor and the alarm of too low blood oxygen value can be caused, and the like, of course, the breathing machine can also carry out the breathing alarm; at this time, the two alarm messages of the breathing alarm and the too low blood oxygen value of the monitor and the breathing alarm of the breathing machine are all triggered or caused by the set parameter of the equipment of the breathing machine, namely the change of the breathing rate, so that the combined alarm can be carried out according to the two alarm messages of the breathing alarm and the too low blood oxygen value of the monitor and the breathing alarm of the breathing machine.

As another example, example 2: changes, e.g. increases, in the dialysis volume of the hemodialysis machine, which results in the patient being infused with a large volume of fluid, which may serve as a temperature alarm, a hypoxia alarm, a hypo-arrhythmia alarm, a hypo-hypotension alarm for the monitor; because the four alarm information of the monitor, namely the temperature alarm, the low blood oxygen value alarm, the low heart rate alarm and the low blood pressure alarm, are all caused or triggered by the set parameter variable of the dialysis amount of the hemodialysis instrument, the combined alarm can be performed according to the four alarm information of the monitor, namely the breathing alarm, the low blood oxygen value alarm, the low heart rate alarm and the low blood pressure alarm.

As another example, example 3: the size of the parameter of the infusion speed of the infusion pump device represents the infusion speed, and if the parameter changes, the heart rate alarm, the blood oxygen value alarm, the blood pressure alarm and the like of the monitor can be caused, so similarly, when the heart rate alarm, the blood oxygen value alarm and the blood pressure alarm of the monitor are triggered by the change of the infusion speed of the infusion pump device, combined alarm can be performed according to the three alarm information of the heart rate alarm, the blood oxygen value alarm and the blood pressure alarm of the monitor.

As another example, example 4: the speed of the anesthesia machine for inputting the anesthetic represents the speed of anesthesia, and if the speed of the anesthesia machine is changed, the heart rate alarm, the breathing alarm and the like of the monitor can be caused, so similarly, when the heart rate alarm and the breathing alarm of the monitor are triggered by the speed change of the anesthesia machine for inputting the anesthetic, the combined alarm can be performed according to the heart rate alarm and the breathing alarm of the monitor.

The above are some descriptions of the joint alarm based on alarm information of one device or a plurality of devices caused by the change of setting parameters of the same device. In some specific embodiments, the joint alarm is performed according to alarm information of one device or multiple devices triggered by the same original event, and for example, the joint alarm may also include: and performing combined alarm according to alarm information of one device or a plurality of devices caused by the same physiological state change.

For example, example 5: when the heart beat rhythm of the patient changes, the heart rate alarm of the monitor, the pulse rate alarm of the blood oxygen value parameter, the pulse rate alarm of the blood pressure parameter and the like can be possibly caused, and because the alarm information is caused by the change of the heart beat rhythm of the patient, the combined alarm can be carried out according to the three alarm information of the heart rate alarm of the monitor, the pulse rate alarm of the blood oxygen value parameter and the pulse rate alarm of the blood pressure parameter.

The above is a description of an aspect of a combined alarm, i.e. a combined alarm is performed according to alarm information of one device or a plurality of devices triggered by the same original event. On the other hand, in some embodiments, the step 140 of performing a joint alarm according to the correlation between the plurality of alarm information further includes: an alert level for the current combination alert is determined. In some specific embodiments, determining the alarm level of the current combination alarm may include: and determining the corresponding alarm level for the current combined alarm according to the critical degree of the patient.

For example, in some embodiments, the patient's criticality may be divided into three levels, from heavy to light.

The first level is: the root cause of such combined alarms is analyzed, which may be dangerous to the patient's life, requiring timely handling by medical personnel, and accordingly, the level of such combined alarms is high-level. For example, in the treatment of hypertension patients, the alarm of an infusion pump and the blood pressure alarm of a monitor form a combined alarm; therefore, the combined alarm represents whether the blood pressure of the patient is abnormal in real time, so that whether the infusion pump is reasonable in medicine delivery is obtained, the life of the patient can be endangered if the medicine is not reasonable, and the level of the combined alarm is high. For another example, the breathing alarm of the breathing machine and the alarm of the breathing alarm of the monitor form a combined alarm; if the breathing rate set by the breathing machine is not reasonable, the breathing alarm of the monitor is triggered, the life of the patient can be endangered, and the level of the combined alarm is high.

The second level is as follows: analyzing the root cause of such combined alarms, which may not pose a danger or an urgent danger to the life of the patient, but require constant attention or intervention by medical personnel, and accordingly, such combined alarms are ranked at a medium level. For example, when in cardiac surgery, the extracorporeal circulation instrument is used for replacing the cardiac pump, and the alarm of the extracorporeal circulation instrument and the heartbeat stop alarm of the monitor form a combined alarm; medical care is required to continue to attend or intervene because the heart has stopped beating, while medical personnel are in the middle of the level of the combined alarm because they are in operation at this time and are in continuous intervention alongside. For another example, the patient has a fast heartbeat, and the alarm of the heart rate of the monitor is triggered to be overhigh, the pulse rate of the blood oxygen value parameter is overhigh and the pulse rate of the blood pressure parameter is overhigh, and the three alarm information form a combined alarm. The heartbeat is fast and will not endanger the life of the patient, but further acceleration is prevented, the medical care is required to pay continuous attention, and the level of the combined alarm is middle.

The third level: analyzing the root cause of such a combined alarm, which may not pose a danger or a more urgent danger to the life of the patient, and which does not require attention and intervention by medical personnel for a short time, and accordingly, is low-ranked. For example, when the hemodialysis machine works, the alarm prompt of the hemodialysis machine and the low body temperature alarm of the monitor form a combined alarm; since hemodialysis can input a large amount of liquid into a human body and discharge the liquid, the body temperature of the human body can be reduced, but the temperature of the human body is not endangered by the patient when the human body is in the treatment period, the attention and the intervention of medical staff are not needed in a short time, and the level of the combined alarm is low.

The above is a description of the aspect of the combined alarm with respect to alarm level. On the other hand, in some embodiments, the step 140 of performing a joint alarm according to the correlation between the plurality of alarm information further includes: and displaying the current combined alarm. The following is a detailed description of how the unified alert is displayed.

In some embodiments, displaying the current federated alert may include: when the same original event triggers the alarm information of the same kind of a plurality of devices, the alarm information can be displayed as only one alarm information. The same kind of alarm information of a plurality of devices triggered by the same original event is only displayed as one alarm information, so that the interference of doctors and staff when watching the alarm information can be reduced. Further, in some embodiments, the display 30 may also display a symbol for further understanding, such as "…" displayed in the vicinity of the one alert message displayed above, which may be clicked by a user via an input device such as a mouse; and in response to clicking on the symbol, display 30 displays both those same types of alerts for multiple devices triggered by the same primitive event and/or displays the same primitive event that triggered those alerts.

For example, referring to fig. 7, in an example, the breathing alarm of the ventilator and the breathing alarm of the monitor are both breathing alarms due to the same original event, for example, the breathing rate parameter of the ventilator changes, and therefore belong to the same kind of alarm information, if the breathing alarm is specifically the alarm information with a high breathing rate, only one alarm information with a high breathing rate is displayed; it can be understood that, if the respiration alarm is specifically alarm information with a low respiration rate at this time, only one alarm information with a low respiration rate may be displayed. Further, a symbol which can be clicked can be displayed near the displayed breathing alarm, and after the user clicks the symbol, the breathing alarm information of the breathing machine and the breathing alarm information of the monitor can be displayed, and/or the original event of the breathing rate parameter change of the breathing machine which causes the breathing alarm information of the breathing machine and the breathing alarm information of the monitor can be displayed.

In some embodiments, displaying the current federated alert may include: when different types of alarm information of a plurality of devices are triggered by the same original event, the alarm information is all displayed. The alarm information is displayed in a centralized manner to carry out combined alarm, so that medical personnel can know the type of the current alarm information and find the reason conveniently. Further, in some embodiments, the display 30 may also display a symbol for further understanding, such as "…" in the interface that collectively displays the above-mentioned alert information, and the user may click on the symbol through an input device such as a mouse; and in response to clicking on the symbol, the display 30 displays the same original event that triggered the different kinds of alert information for the multiple devices.

For example, referring to fig. 8, in one example, the same original event, such as the change of the infusion speed of the infusion pump, causes the bubble alarm of the infusion pump and the blood pressure alarm of the monitor, which belong to different types of alarm information, and they are combined into a combined alarm to be displayed in a centralized manner, so that the medical care can know the type of the current alarm and the reason for triggering the alarm. Furthermore, a clickable symbol can be displayed in an interface or an area for intensively displaying the bubble alarm of the infusion pump and the blood pressure alarm of the monitor, and when a user clicks the symbol, the original event causing the two alarm messages, namely the infusion speed of the infusion pump, can be displayed too fast.

In some embodiments, displaying the current federated alert may include: when different kinds of alarm information of a plurality of devices are triggered by the same original event, the alarm information is classified and displayed as an alarm of the same original event. The reasons of the alarm information of different types are analyzed and classified into the alarm of the same original event, so that medical personnel can conveniently know the reasons of the current alarm information. Further, in some embodiments, the display 30 may also display a symbol for further understanding, such as "…" displayed near the alarm of the same original event, which the user may click on via an input device such as a mouse; and in response to clicking of the symbol, the display 30 displays various kinds of alarm information of the above-described plurality of devices.

For example, referring to FIG. 9, in one example, a bubble alarm of an infusion pump and a blood pressure alarm of a monitor, which are different types of alarm information, are caused by the same primitive event, such as a change in infusion rate of the infusion pump, and are categorized and displayed as an alarm that the infusion pump is too fast in infusion rate, which may allow healthcare to understand the reason for triggering the alarm. Furthermore, a clickable symbol can be displayed near the alarm of the infusion pump with too high infusion speed, and after the user clicks the symbol, the classified alarm information can be displayed, namely, the bubble alarm of the infusion pump and the blood pressure alarm of the monitor are displayed.
