Airbed type device for automatic monitoring breath, heartbeat, and turn over of human body, and monitoring method

Abstract

An air cushion type automatic monitor for the respiration, palpitation and turn-over of human body and its monitor method are disclosed. Said monitor method includes such steps as receiving the pressure signals generated by respiration, cardiac rhythm and turning body over, removing interference signals by microprocessor, using differential algorithm to judge wave peaks and wave valleys, judging the relative information according to the amplitudes and variation speed of peak and valley, statistics of respiration and ardiac rhythm frequencies, and alarming.

Description

technical field [0001] The invention relates to a human body vital information monitoring device and a monitoring method thereof, in particular to an automatic monitoring device and a monitoring method for automatically realizing the human body's breathing, heartbeat and turning over. Background technique [0002] Breathing, heartbeat and turning over monitoring are very important for children and sick people. For example, the various organs of newborns are not yet fully developed, and their ability to adapt to the environment is relatively weak, and they are prone to high fever or suffocation that is life-threatening. In addition, it is easy for a child to fall off the bed when turning over while sleeping, and he will turn over and crawl when he wakes up, which is also very dangerous, so others need to be constantly supervised. Similarly, patients with some diseases also need others to constantly monitor their breathing, heartbeat and turning over. Also, when the patient ...

AI Technical Summary

Problems solved by technology

However, sound waves attenuate rapidly in the air, making monitoring very difficult; infrared rays are difficult to penetrate clothes and bedding; lasers can overcome these shortcomings to achieve accurate detection, but laser monitoring requires accurate positioning and specific parts related to breathing and heartbeat from time to time, which gives the The application of technology has brought great difficulties; there are also precedents of using microwave radar to monitor infant breathing abroad, but due to the safety of microwave, the large size of the detection device, the problem of power supply, the limitation of performance and price ratio, and the immaturity of the basic principle of detection, etc. Due to the existence of problems, the application research of microwave radar in the field of biomedicine is not extensive.

In addition, the current respiratory monitoring technology is to directly attach the sensor to the human body. Since the sensor generally has a metal component, this has an impact on X-ray chest X-ray and CT imaging.
