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 o

Embodiment Construction

[0020] As shown in Figure 1, the air cushion type human respiration, heartbeat and stand-up automatic monitoring device system composition diagram of the present invention, wherein: 1, air cushion, 2, human body, 3, bed, 4, gas conduit, 5, air pressure sensor, 6, signal Conditioning circuit, 7, microprocessor, 8, alarm transmitting part, 9, alarm receiving part.

[0021] Figure 2 shows the air pressure waveform with human respiration, heartbeat and turning over.

[0022] The air pressure sensor (5) is connected to the air cushion (1) through the gas conduit (4), and the microprocessor (7) can obtain the air cushion (1) due to the breathing, heartbeat and turning over of the human body (2) through the air pressure sensor signal conditioning circuit (6). The generated air pressure information is de-noised by compound filtering to obtain the air pressure waveform shown in Figure 2, and then the peak and trough in the air pressure waveform are judged by the difference algorithm, a...

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 ...
