Abstract

The invention discloses a wireless respiration monitoring device, comprising a monitoring circuit, a piezoelectric film sensor and an antenna, wherein the control circuit is respectively and electrically connected with the piezoelectric film sensor and the antenna. In the wireless respiration monitoring device, the piezoelectric film sensor is used for sensing respiratory movement and converting the respiratory movement into corresponding charge signals, the control circuit is used for processing the charge signals to obtain a corresponding monitoring result, and the antenna is used for transmitting the monitoring result out. Because the piezoelectric film sensor adopted in the invention has the favorable characteristics of high response speed, high sensitivity and good linearity, the accuracy and the correctness of respiration signals are guaranteed; and in addition, because the antenna is used for transmitting the monitoring result out and cables or other transmission lines are avoided being used, the wireless respiration device provided by the invention has a simple structure and is easy to produce and manufacture.

Description

technical field [0001] The invention relates to the fields of packaging technology and sensor technology, in particular to a wireless respiration monitoring device. Background technique [0002] There are three traditional respiratory monitoring methods: the first is the impedance sensing method, the electrode sheet is attached to the human chest, a low-frequency current flows through the thorax, and the current change is used to collect the respiratory signal by the ups and downs of the thorax; the second is The first is capnography, which uses the amount of carbon dioxide exhaled by the human body to detect breathing; the third is the thermal sensing method, which collects respiratory signals through temperature changes caused by exhalation and inhalation. [0003] Among them, the second method requires nasal intubation, which has certain risks in clinical operation, and the current detection equipment is mainly imported, and the price is very high, so the first and second...
