Monitor and automatic multi-lead signal switching method and device thereof

Abstract

A method for automatically switching signals of a plurality of leads. The method comprises: respectively collecting vital sign signals detected by a plurality leads (101); selecting one path of signals from the vital sign signals output by the plurality of leads to be an analysis signal, the analysis signal being a signal used for subsequently conducting monitoring analysis and processing (103); and detecting, in real time, whether the current analysis signal is abnormal, and if so, selecting another path of vital sign signals output by a lead to be an analysis signal (104). Also disclosed is a device for automatically switching signals of a plurality of leads, comprising a signal acquisition unit (201), a signal selection unit (203) and a judgement unit (204). Also disclosed is a monitor comprising the device for automatically switching signals of a plurality of leads. The monitor and the method and device for automatically switching signals of a plurality of leads thereof can automatically switch a lead corresponding to the current analysis signal to another normal lead when the lead is abnormal, so as to obtain correct vital sign signals, and thereby avoiding the situation of a false alarm caused by a single abnormal lead.

Description

technical field [0001] The present application relates to a monitor, in particular to a method and device for automatically switching multi-lead signals of the monitor. Background technique [0002] Medical monitoring equipment (such as monitors) can provide real-time and accurate patient vital signs and other important information to medical staff, so that clinicians can more comprehensively, timely and accurately grasp the changes in patients' conditions, and provide important information for formulating treatment plans and emergency treatment. It provides important evidence to help patients obtain the best treatment effect, so it is widely used in ICU, CCU, anesthesia operating room and other related clinical departments of the hospital. [0003] A monitor usually has multiple leads, and the medical staff selects only one of the leads as the analysis lead based on observation and human judgment, and only the signal output by the analysis lead is processed as an effective ...

AI Technical Summary

Problems solved by technology

The problem caused by this way of fixing the analysis lead is: when the signal output by the lead is abnormal, it will cause an alarm. During the monitoring process, it is caused by poor contact with the patient's skin or other interferences that lead to weak signals. In this case, false alarms will be caused, which will bring a lot of inconvenience to clinical operations and monitoring.
