Background

The alarm conditions of different types of alarms (from the same type of physiological characteristics or different types of physiological characteristics) in the current alarm system are mutually independent, and corresponding alarms can be reported as long as the respective alarm conditions are met. This approach has the following disadvantages: since various physiological characteristics are correlated, for example, a change in blood circulation may be caused when arrhythmia occurs, and the change in blood circulation should be recognized more sensitively than normal so as to more accurately recognize the state of the patient, if a fixed alarm condition is used for the blood circulation, a condition that the state of the patient is deteriorated may not be recognized in time clinically; in addition, as in the case of one type of physiological characteristics, two types of alarm conditions exist, the alarm conditions are fixed thresholds set by a user, and although the alarm conditions of the two types of alarms are different from the priorities, when a patient signal meets one alarm condition and the other alarm condition at the same time, the two types of alarms are possibly reported alternately, so that the problem of alarm fatigue is brought to the user.

An alarm 116 connected to the controller 113 for performing at least one of the following steps: outputting first alarm information when receiving a first alarm instruction; outputting second alarm information when receiving a second alarm instruction; and outputting third alarm information when receiving the third alarm instruction. Through the self-adaptive alarm device, the disease state type of the patient and the deterioration condition of the state of the patient can be accurately identified, and the alarm frequency is reduced so as to achieve the purpose of reducing alarm fatigue.

Specifically, the parameter obtainer 112 at least comprises a parameter obtainer 112 corresponding to a physiological characteristic, the parameter obtainer 112 at least comprises at least one parameter obtainer 112 selected from an electrocardiosignal parameter obtainer 112, a respiration parameter obtainer 112, a body temperature parameter obtainer 112, an blood oxygen parameter obtainer 112, a non-invasive blood pressure parameter obtainer 112, an invasive blood pressure parameter obtainer 112, and the like, and each parameter obtainer 112 is respectively connected with an externally inserted sensor accessory 111 through a corresponding sensor interface. The sensor accessory 111 includes a detection accessory corresponding to detection of physiological characteristics such as electrocardio, respiration, blood oxygen, blood pressure, body temperature and the like. Correspondingly, the first measurement parameter and/or the second measurement parameter comprises at least one of the following parameters: electrocardio parameters, respiration parameters, blood oxygen parameters, blood pressure parameters, body temperature parameters and the like. The parameter acquirer 112 is mainly used to connect the sensor accessory 111 to obtain the acquired physiological characteristic signal, and may include at least two measurement circuits of physiological characteristics, and the parameter acquirer 112 may be, but is not limited to, a physiological characteristic measurement circuit (module), a human physiological characteristic measurement circuit (module), or a sensor to acquire human physiological characteristics. Specifically, the parameter acquirer 112 acquires the physiological sampling signal of the relevant patient from the external physiological characteristic sensor accessory 111 through the expansion interface, and processes the physiological sampling signal to obtain physiological data for alarming and displaying. The expansion interface can also be used for outputting a control signal which is output by the controller 113 and relates to how to acquire the physiological characteristics to an external physiological characteristic monitoring accessory through the corresponding interface, so that the monitoring and control of the physiological characteristics of the patient are realized. It is understood that the parameter acquirer 112 may be a component or a device such as a sensor, a probe, a central station, a storage device (hard disk, optical disk, usb disk), etc., which may be a single element, device, circuit, or may be composed of multiple elements, devices, circuits, as long as it can be used for measuring the parameter corresponding to the physiological characteristic, and the specific form thereof is not limited herein.

The controller 113 needs to include at least one processor and at least one memory, and of course, the controller 113 may further include at least one of a power management module, a power IP module, an interface conversion circuit, and the like. The power management module is used for controlling the on and off of the whole machine, the power-on time sequence of each power domain in the board card, the charging and discharging of the battery and the like. The power supply IP block refers to a power supply module that associates a schematic diagram of a power supply circuit unit frequently called repeatedly with a PCB layout and solidifies the schematic diagram into individual power supply modules, that is, converts an input voltage into an output voltage through a predetermined circuit, wherein the input voltage and the output voltage are different. For example, a voltage of 15V is converted into 1.8V, 3.3V, 3.8V, or the like. It is understood that the power supply IP block may be single-pass or multi-pass. When the power supply IP block is single-pass, the power supply IP block may convert an input voltage into an output voltage. When the power IP module is the multichannel, the power IP module can be a plurality of output voltage with an input voltage conversion, and a plurality of output voltage's magnitude of voltage can be the same, also can not be the same to can satisfy a plurality of electronic component's different voltage demands simultaneously, and the module is few to the external interface, and the work is black box and external hardware system decoupling zero in the system, has improved whole electrical power generating system's reliability. The interface conversion circuit is used for converting signals output by the minimum system control module (i.e., at least one processor and at least one memory in the controller 113) into input standard signals required to be received by an actual external device, for example, supporting an external VGA display function, converting RGB digital signals output by the main control CPU into VGA analog signals, supporting an external network function, and converting RMII signals into standard network differential signals. When the controller includes a processor, the processor may be an Intel processor or other processor.

In addition, the adaptive alarm device or system may further include one or more of a local display 114, an input interface circuit 117, an external communication and power interface 115. The controller 113 is used to coordinate and control the boards, circuits and devices in the multi-parameter monitor or module assembly. In this embodiment, the controller 113 is configured to control data interaction between the parameter acquirer 112 and the communication interface circuit and transmission of the control signal, and transmit the physiological data to the display 114 for display, and also receive a user control instruction input from the physical input interface circuit 117 such as a touch screen, a keyboard, a key, and the like, and of course, output a control signal on how to acquire the physiological characteristic. The alarm 116 may be an audible and visual alarm 116, or may be a display 114 that outputs visual alarm information, such as text, graphics, colors, etc. The controller 113 performs the calculation of the physiological characteristics, and sends the calculation result and the waveform of the parameters to a host (such as a host with a display 114, a PC, a central station 211, etc.) through the external communication and power interface 115, where the external communication and power interface 115 may be one or a combination of a local area network interface composed of Ethernet (Ethernet), Token Ring (Token Ring), Token Bus (Token Bus), and backbone Fiber Distributed Data Interface (FDDI) as 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 and power interface 115 may also be one or a combination of a wireless data transmission interface and a wired data transmission interface. The host can be any computer equipment of a host computer of a monitor, an electrocardiograph, an ultrasonic diagnostic apparatus, a computer and the like, and matched software is installed to form the monitor equipment. The host can also be communication equipment, such as a mobile phone, and the multi-parameter monitor or the module component sends data to the mobile phone supporting Bluetooth communication through the Bluetooth interface to realize remote transmission of the data.

The self-adaptive alarm device can be arranged outside the monitor shell and used as an independent external parameter insertion module, a plug-in monitor can be formed by a host (comprising a main control board) inserted into the monitor and used as a part of the monitor, or the self-adaptive alarm device can be connected with the host (comprising the main control board) of the monitor through a cable, and the external parameter insertion module is used as an external accessory of the monitor. Of course, the parameter processing can also be arranged in the shell and integrated with the main control module, or physically separated and arranged in the shell to form the integrated monitor.

It is to be understood that the "device" may include a single element or a plurality of elements or components, as long as the functions of measuring, controlling, alarming, etc. corresponding parameters are achieved, and is not limited herein.

The first alarm condition may be a preset prompt condition of the first measurement parameter set by the user, that is, an alarm condition when the first measurement parameter is abnormal. The second alarm condition and the third alarm condition may be preset prompt conditions of the second measurement parameter set by the user, that is, alarm conditions when the second measurement parameter is abnormal. First alarm information, second alarm information and third alarm information all can report out through modes such as sound, light, characters, electricity, vibrations. The second alarm information and the third alarm information may be the same or different, and are not limited herein.

In an embodiment, when it is determined that the first measurement parameter does not satisfy the first alarm condition and the second measurement parameter satisfies a second alarm condition corresponding to the second measurement parameter, the controller 113 sends a second alarm instruction to control the alarm 116 to output second alarm information to alarm the second measurement parameter. In this case, when the first measurement parameter does not satisfy the first alarm condition and the second measurement parameter satisfies the second alarm condition, an alarm is given to the second measurement parameter. For example, the first measurement parameter is an electrocardiographic parameter, the second measurement parameter is blood pressure or blood oxygen, and the alarm 116 only alarms on blood pressure or blood oxygen when the electrocardiographic parameter is determined not to satisfy the first alarm condition and the blood pressure or blood oxygen satisfies the second alarm condition.

When the first measurement parameter satisfies the first alarm condition, the controller 113 outputs a first alarm instruction to control the alarm 116 to alarm the first measurement parameter. The controller 113 sets the second alarm condition for the second measurement parameter as a third alarm condition when the first measurement parameter satisfies the first alarm condition, and alarms only for the first measurement parameter when the second measurement parameter does not satisfy the third alarm condition. For example, the first measurement parameter is an electrocardiographic parameter, the second measurement parameter is blood pressure or blood oxygen, when it is determined that the electrocardiographic parameter satisfies the first alarm condition, the controller 113 sets the second alarm condition of blood pressure or blood oxygen as a third alarm condition, and if the blood pressure or blood pressure does not satisfy the third alarm condition, the alarm 116 outputs only the first alarm information related to the electrocardiographic parameter. On the other hand, when the second measurement parameter satisfies the third alarm condition, the alarm 116 will alarm the second measurement parameter. At this point, the alarm 116 may optionally cease alerting the first measured parameter. For example, when the electrocardiogram parameter satisfies the first alarm condition and the blood oxygen or blood pressure satisfies the third alarm condition, the alarm 116 stops outputting the first alarm information and stops alarming the electrocardiogram parameter; and outputting third alarm information related to the blood pressure or the blood oxygen to alarm the blood pressure or the blood oxygen. The second alarm information can be the same as the third alarm information and both prompt that the blood pressure or the blood oxygen is out of limit; the second alarm information and the third alarm information may also be different, for example, the second alarm information includes a second alarm condition, and the third alarm information includes a third alarm condition; or the two are reported in different forms, so that the user can distinguish the two conveniently.

Due to the correlation between the first measurement parameter and the second measurement parameter, when the first measurement parameter changes, the second measurement parameter may need to be reported more sensitively, and at this time, the second alarm condition to the third alarm condition that the second measurement parameter is more easily satisfied can accurately identify the disease condition type of the patient and the deterioration condition of the patient state. On the other hand, due to the correlation between the first measurement parameter and the second measurement parameter, when the alarm is performed on the first measurement parameter, the alarm of the second measurement parameter may be accompanied by the alarm of the second measurement parameter, and the alarm of the second measurement parameter even interrupts the alarm of the first measurement parameter, or the alarm fatigue problem is caused by the occurrence of alternative alarm. It can be understood that the first measured parameter can reach the first alarm condition more easily than the second measured parameter can reach the second alarm condition, so that the alarm accuracy can be ensured and the alarm can not be missed while the problem of alarm fatigue is solved.

The controller 113 sets the second alarm condition to a third alarm condition, including: and setting a threshold value factor and/or a time factor in the second alarm condition to obtain a third alarm condition, wherein the third alarm condition is used for inhibiting or promoting the output of second alarm information.

The case where the controller 113 sets the alarm of the second measurement parameter will be specifically described as follows.

In the first case, the controller 113 controls the suppression of the alarm of the second measured parameter. When the third alarm condition is more difficult to be satisfied than the second alarm condition, it may be considered that the controller 113 suppresses the alarm of the second measurement parameter and suppresses the output of the second alarm information.

The control of the suppression of the alarm of the second measured parameter by the controller 113 may be achieved by setting a threshold factor and/or a time factor in said second alarm condition. In one embodiment, this approach includes: and setting the second alarm threshold value as at least one of a third alarm threshold value, an alarm refractory period of the second measurement parameter and an alarm delay time of the second measurement parameter. It is understood that "setting" herein includes: any mode such as adding, canceling, lifting, lowering, lengthening, shortening and the like can be adopted as long as the purpose of changing the second alarm condition to be the third alarm condition can be achieved.

In one embodiment, the second alarm condition includes a second alarm threshold; said setting a threshold factor in said second alarm condition to result in a third alarm condition, comprising: raising or lowering the second alarm threshold to obtain a third alarm threshold; the alarm 116 is configured to output the third alarm information when the second measurement parameter satisfies the third alarm threshold. The user sets a second alarm condition of the second measurement parameter, and when the first measurement parameter reaches the first alarm condition, the controller 113 automatically raises or lowers the second alarm condition of the second measurement parameter to obtain a third alarm condition, so that the third alarm condition is more difficult to satisfy than the second alarm condition.

In one embodiment, the physiological characteristic signal is an electrocardiographic characteristic signal, the first measurement parameter is a statistical parameter, the second measurement parameter is a rhythm parameter, when the statistical parameter satisfies a first alarm condition, the alarm 116 first alarms the statistical parameter, and the controller 113 controls to increase the second alarm condition to a third alarm condition of the rhythm parameter. When the rhythm class parameter satisfies the third alarm condition, the controller 113 controls the alarm 116 to alarm the rhythm class parameter. Optionally, the alarm 116 stops alarming the statistical class parameter.

In one embodiment, the statistical type parameter is the number of ventricular contractions (PVCs/min) in the early stage per minute, the rhythm type parameter is the logarithm of the bigeminy and the trigeminy, the second alarm condition of the bigeminy and the trigeminy is 3 pairs, and when the PVCs/min meets the first alarm condition, the controller 113 controls the alarm 116 to alarm the PVCs/min and sends out first alarm information; on the other hand, the controller 113 controls the alarm conditions of the two-joint law and the three-joint law to be improved from the second alarm condition 3 pair to the third alarm condition 10 pair, and if the logarithm of the two-joint law and the three-joint law meets 10 pairs, the controller 113 controls the alarm 116 to alarm the two-joint law and the three-joint law and send out third alarm information. Optionally, the processing module 3 controls the alarm 116 to stop alarming for PVCs/min while controlling the alarm 116 to send out the third alarm information.

In one embodiment, the controller 113 sets the time factor in the second alarm condition to obtain a third alarm condition, which specifically includes at least one of the following steps: setting the second alarm condition to comprise an alarm refractory period of the second measurement parameter to obtain a third alarm condition; and setting the second alarm condition to comprise the delay time of the alarm of the second measurement parameter so as to obtain a third alarm condition.

Wherein the first alarm refractory period is a first preset time period from when the first measurement parameter satisfies the first alarm condition. When the second alarm condition comprises a second alarm threshold, the controller 113 is further configured to perform one of the following steps: when the second measurement parameter meets the second alarm threshold and the time when the second measurement parameter meets the second alarm threshold is beyond an alarm refractory period, outputting a third alarm instruction; or when the second measurement parameter meets a third alarm threshold set by a second alarm threshold and the time when the second measurement parameter meets the third alarm threshold is beyond an alarm refractory period, outputting a third alarm instruction. The alarm 116 outputs third alarm information after receiving the third alarm instruction. It is understood that the controller 113 may also control the alarm 116 to stop outputting the first alarm information through the third alarm instruction, thereby stopping the alarm on the first measured parameter.

Similarly, taking the first measurement parameter as the statistic parameter and the second measurement parameter as the rhythm parameter as an example, when the statistic parameter satisfies the first alarm condition, the alarm 116 alarms the statistic parameter, and the controller 113 controls the alarm refractory period for setting the rhythm parameter. If the rhythm parameter meets the second alarm threshold value or a third alarm threshold value obtained by adjusting the second alarm threshold value after the first preset time period of the alarm refractory period is finished, the controller 113 controls the alarm 116 to alarm the rhythm parameter; optionally, the controller 113 controls the alarm 116 to stop alarming the statistic class parameter.

In an embodiment, the statistical type parameter is the number of ventricular contractions (PVCs/min) in the early stage per minute, the rhythm type parameter is the logarithm of the bigeminal and tripartitic rhythms, the second alarm threshold of the bigeminal and tripartitic rhythms is 3 pairs, and when the PVCs/min exceeds the limit and meets the first alarm condition, the alarm 116 alarms the PVCs/min and outputs first alarm information. In one embodiment, the controller 113 controls to set a first alarm refractory period of the double-link and triple-link, and when the time when the second alarm threshold is met by the double-link and triple-link is beyond the first alarm refractory period, the controller 113 controls the alarm 116 to alarm the double-link and triple-link.

In another embodiment, the controller 113 increases the alarm threshold of the double-linkage rate and the triple-linkage rate from the second alarm threshold 3 pair to the third alarm threshold 10 pair, and sets the alarm refractory period of the double-linkage rate and the triple-linkage rate, and when the time when the double-linkage rate and the triple-linkage rate meet the third alarm threshold is beyond the alarm refractory period, the controller 113 controls the alarm 116 to alarm the double-linkage rate and the triple-linkage rate. At the same time, optionally, the overrun alarm to PVCs/min is stopped.

In one embodiment, the time factor includes a first alarm delay time or a second alarm delay time. The first alarm delay time is a second preset time period from the time when the second measurement parameter meets the second alarm condition; the second alarm delay time is a second preset time period from when the second measurement parameter satisfies the third alarm condition. When the second alarm condition comprises a second alarm threshold, the controller is further configured to perform one of: when the second measurement parameter meets a second alarm threshold value, delaying the first alarm delay time and outputting a third alarm instruction; or, when the second measurement parameter meets a third alarm threshold value obtained by adjusting a second alarm threshold value, delaying the second alarm delay time and outputting the third alarm instruction.

In this manner, the alarm 116 delays the alarm for the second measurement parameter by the corresponding first alarm delay time and second alarm delay time after the second measurement parameter satisfies the second alarm condition and/or the third alarm condition. In this embodiment, when the first measurement parameter satisfies the first alarm condition, the alarm 116 alarms the first measurement parameter, and in order to avoid the problem of alarm fatigue, the controller 113 sets an alarm delay time for the second measurement parameter, and in the alarm delay time for the second measurement parameter, the alarm 116 alarms only the first measurement parameter. When the second measurement parameter satisfies the second alarm condition or the third alarm condition and is delayed to the corresponding first alarm delay time or the second alarm delay time, the controller 113 outputs a third alarm instruction to control the alarm 116 to alarm the second measurement parameter. Optionally, the controller 113 stops the alarm 116 from alarming the first measured parameter at the same time.

Similarly, taking the first measurement parameter as the statistical parameter and the second measurement parameter as the rhythm parameter as an example, when the statistical parameter satisfies the first alarm condition, the alarm 116 alarms the rhythm parameter, and the controller 113 controls to set the first alarm delay time or the second alarm delay time of the rhythm parameter. When the rhythm parameter meets the second alarm threshold and the first alarm delay time is over, the controller 113 controls the alarm 116 to alarm the rhythm parameter; alternatively, when the rhythm class parameter satisfies the third alarm threshold and the second alarm delay time is over, the controller 113 controls the alarm 116 to alarm the rhythm class parameter. Optionally, the controller 113 simultaneously controls the alarm 116 to stop alarming the statistic class parameter.

In an embodiment, the statistic parameter is the number of ventricular contractions (PVCs/min) in the early stage per minute, the rhythm parameter is the logarithm of the bigeminal and trigemional rhythms, the second alarm threshold of the bigeminal and trigemional rhythms is 3 pairs, when the PVCs/min is out of limit and meets the first alarm condition, the alarm 116 alarms the bigeminal and trigemional rhythms in an out-of-limit mode, the controller 113 controls and sets the first alarm delay time of the bigeminal and trigemional rhythms alarm, and when the bigeminal and trigemional rhythms alarm reaches 3 pairs and the first alarm delay time is over, the controller 113 controls the alarm 116 to alarm the bigeminal and trigemional rhythms.

In another embodiment, the statistic parameter is the number of ventricular contractions (PVCs/min) in the early stage per minute, the rhythm parameter is the logarithm of the bigeminy and the trigeminy, the second alarm threshold of the bigeminy and the trigeminy is 3 pairs, when the PVCs/min is out of limit and meets the first alarm condition, the alarm 116 alarms for the over limit of the PVCs/min, the controller 113 controls and sets the third alarm threshold of the bigeminy and the trigeminy to be 10 pairs and the second alarm delay time of the bigeminy and the trigemiy, and when the bigeminy and the trigemiy alarm reaches 10 pairs and the second alarm delay time is over, the controller 113 controls the alarm 116 to alarm the bigeminy and the trigemiy. Alternatively, the controller 113 controls the alarm 116 to stop the alarm of the PVCs/min overrun.

From the foregoing, it can be appreciated that in other embodiments, the controller 113 controlling the suppression of the alarm of the second measured parameter includes: and the second alarm threshold value is promoted to obtain at least one of a third alarm threshold value, an alarm refractory period of the second measurement parameter and alarm delay time of the second measurement parameter. That is, the alarm may be given to the second measurement parameter when the second measurement parameter satisfies one or more of the above-described conditions and the alarm is suppressed. Therefore, the controller 113, regardless of whether it controls to suppress the alarm of the second measurement parameter in one or more of the three manners described above, can avoid alarm fatigue caused by simultaneously alarming the first measurement parameter and the second measurement parameter, and can more accurately determine the physiological condition and deterioration condition of the monitored subject.

Furthermore, in a specific embodiment, the physiological characteristic signal is an electrocardiographic characteristic signal. The first measurement parameter and the second measurement parameter are any two of various types of parameters such as ventricular rate, non-continuous ventricular rate, multi-burst ventricular premature, paired ventricular premature, single ventricular premature and the like. When a patient with ventricular premature beat occurs, any two of ventricular premature beats of various types such as ventricular rate, non-continuous ventricular rate, multiple-burst ventricular premature beats, paired ventricular premature beats, single ventricular premature beats and the like occur due to the change of signal forms along with time, the two alarms can be continuously reported and switched, and the alarm fatigue problem can be caused.

This application can set up the parameter that the priority of reporting to the police is high and be first measurement parameter, the parameter that the priority of reporting to the police is low is the second measurement parameter, thereby alarm system gives an alarm to first measurement parameter in priority, promote the second alarm condition that the second measured parameter to the third alarm condition that more difficult satisfied, when the second measured parameter satisfies the third alarm condition, report to the police to the second measurement parameter this moment, stop the warning to first measurement parameter, thereby can reduce the tired problem of warning. The manner in which the second alarm condition is set as the third alarm condition may also be performed in at least one of the manners described above.

If the physiological characteristic signal is a blood oxygen characteristic signal. The first measurement parameter is a weak perfusion parameter and the second measurement parameter is a search pulse parameter. When the blood oxygen pulse signal of a patient is weak, weak perfusion and pulse searching alarm can occur simultaneously or alternatively, so that the alarm fatigue problem is caused. If weak perfusion alarm is detected, the alarm condition of the searched pulse can be enhanced to a third alarm condition which is more difficult to meet, and if the alarm condition of the searched pulse is improved to be that the search pulse alarm condition needs to be met continuously for 6 seconds, the searched pulse is allowed to alarm. The manner in which the second alarm condition is set as the third alarm condition may also be performed in at least one of the manners described above.

Therefore, when the first measurement parameter and the second measurement parameter both meet the alarm condition, the physiological characteristic of the second is set, so that the alarm fatigue caused by alternative alarm of the two types of physiological characteristics can be avoided, and meanwhile, the deterioration condition of the state of the patient can be timely and accurately identified.

In one embodiment, the controller 113 controls the prompting of the alert for the second measured parameter.

At this time, the third alarm condition is easier to satisfy than the second alarm condition, which may include any one of the following: the second alarm threshold is set to a third alarm threshold that is easier to satisfy, and the alarm refractory period or alarm delay time in the second alarm condition is cancelled or reduced.

In one embodiment, the physiological characteristic signal comprises a first physiological signal and a second physiological signal, and the controller is further configured to derive the first measured parameter from the first physiological signal and derive the second measured parameter from the second physiological signal.

Take the first measurement parameter as the electrocardiographic parameter and the second measurement parameter as the blood pressure or blood oxygen for example. When the electrocardiogram parameter meets the first alarm condition, the alarm 116 alarms on the electrocardiogram parameter, and the second alarm condition for controlling the blood pressure or the blood oxygen by the controller 113 is set as a third alarm condition which is easier to meet. When it is determined that the blood pressure or blood oxygen satisfies the third alarm condition, the alarm 116 alarms the blood pressure or blood oxygen. Optionally, the alarm 116 stops alarming the electrocardiographic parameter, thereby avoiding alarm fatigue caused by alarming the first measurement parameter and the second measurement parameter at the same time.

When the electrocardio parameters of a patient are abnormal, the abnormal change of the blood pressure or the blood oxygen is often caused, and if the blood pressure or the blood oxygen adopts a fixed second alarm condition, the abnormal change of the blood pressure or the blood oxygen can not be identified. On the other hand, since arrhythmia may cause a change in blood circulation when it occurs, a change in blood oxygen or blood pressure should be recognized more sensitively than normal in order to more accurately identify the state and potential danger of the patient. Therefore, in this embodiment, when the monitoring target state is identified as being an arrhythmia when the electrocardiographic parameter satisfies the first alarm condition, the controller 113 controlling the setting of the alarm of blood pressure or blood oxygen may control the alarm of blood pressure or blood oxygen to be promoted for the controller 113, i.e., control so that the alarm of blood pressure or blood oxygen is more easily triggered.

Of course, the first measurement parameter may also be blood pressure or blood oxygen, and the second measurement parameter is an electrocardiographic parameter. When blood oxygen or blood pressure is abnormal, the alarm condition of the electrocardio parameters is reduced, so that the condition that the heart rate changes can be found more quickly, and dangers can be found in advance.

Of course, the first measurement parameter may also be a blood pressure parameter, the second measurement parameter is a heart rate parameter, when the patient gives an alarm when the blood pressure is too high, that is, the blood pressure parameter of the patient satisfies the first alarm condition, the alarm 116 gives an alarm to the blood pressure, the controller 113 sets the alarm condition for reducing the heart rate parameter, that is, the second alarm condition for reducing the heart rate parameter is set as the third alarm condition which is easier to reach, so that the alarm 116 gives an alarm to the heart rate parameter once the heart rate of the patient is too high, when the third alarm condition is satisfied, the user can timely find the situation that the heart rate becomes high, and find danger in advance.

An alarm 116 connected to the controller 113 for performing at least one of the following steps: outputting first alarm information when receiving a first alarm instruction; outputting second alarm information when receiving a second alarm instruction; and outputting third alarm information when receiving the third alarm instruction.

As shown in fig. 2, the present application further provides a monitor networking system for use in a hospital, which can integrally store data of a monitor, centrally manage patient information and nursing information, and store the patient information and the nursing information in association, so as to facilitate storage of historical data and association alarm.

In addition, each bedside monitor 212 can also be paired with a portable monitoring device 213 for transmission, the portable monitoring device 213 provides a simple and portable multi-parameter monitor or module, and can be worn on the body of a patient to perform mobile monitoring corresponding to the patient, and physiological data generated by the mobile monitoring can be transmitted to the bedside monitor 212 for display after the portable monitoring device 213 is in wired or wireless communication with the bedside monitor 212, or transmitted to the central station 211 for a doctor or a nurse to view through the bedside monitor 212, or transmitted to the data server 215 for storage through the bedside monitor 212. In addition, the portable monitoring device 213 can also directly transmit the physiological data generated by the mobile monitoring to the central station 211 through the wireless network node 214 arranged in the hospital for storage and display, or transmit the physiological data generated by the mobile monitoring to the data server 215 through the wireless network node 214 arranged in the hospital for storage.
