Description

Life information monitor with cardiac emergency device

This application claims priority to Chinese Patent Application No. 201521110631.5, entitled "Life Information Monitor with Cardiac Emergency Device", filed on December 30, 2015, the entire contents of which are incorporated by reference. In this application.

Technical field

The present application belongs to the technical field of medical device for life science human health monitoring, and particularly relates to a cardiac life information monitor.

Background technique

It is well known in the industry that heart and stroke is one of the causes of cardiovascular and cerebrovascular diseases. Most of the reasons are that the time for hospital rescue has passed. If it can be sent to the hospital for treatment in time, most patients may pass the dangerous period. Get a recovery. However, if the field personnel do not understand medicine, they can only wait for the ambulance to arrive. If the arrest is more than 8 minutes, it is too late; if the pacing or defibrillation treatment can be performed in time, some patients may recover immediately. Therefore, in order to prevent and promptly rescue stroke patients, reduce mortality, and improve the quality of care and rescue, various cardiac monitoring systems have emerged. For example, "a portable personal care system for human heart patients" disclosed in Chinese Patent No. CN201210441707, "Cone Remote Monitoring and Diagnosis System Based on Wireless Communication Technology" disclosed in CN200910030595 is two examples. However, both of these monitoring techniques have a common flaw, that is, they can only be used for remote monitoring and transmission display processing. It is still necessary to obtain real-time data from the monitoring service center or control center before taking a first aid plan and then implementing rescue services. Can not rescue in time, to win the best time to rescue.
