Embodiment 1

[0028] Example 1: A flexible respiratory monitoring device based on temperature sensing

[0029] This embodiment is a flexible breathing monitoring device based on temperature sensing. The basic principle is to use the temperature resistance effect of the nano-metal strip to monitor the temperature difference in the exhaled and inhaled gas to monitor the respiratory signal. The temperature of the exhaled gas is close to the temperature of the lungs of the human body, while the temperature of the inhaled gas is close to room temperature. The respiratory signal can be monitored by monitoring this temperature change through the temperature sensor, so that the waveform diagram reflecting the breathing behavior can be obtained. The amplitude of the waveform diagram reflects the exhalation The absolute value of the gas temperature also reflects the breathing amplitude, and the Fourier transform is performed on the waveform to obtain the breathing frequency, and the breathing informat...

Embodiment 2

[0046] Example 2: A flexible respiratory monitoring device based on humidity sensing

[0047] This embodiment is a flexible respiratory monitoring device based on humidity sensing. The basic principle is to use the optical fiber film with a micro-nano structure and chemical modification to be sensitive to the water vapor content in the environment to monitor the humidity change in the exhaled and inhaled gas, and to monitor the respiratory signal. Monitoring (Kang, Y., Ruan, H., Wang, Y., Arregui, F.J., Matias, I.R., & Claus, R.O. (2006). Nanostructured optical fiber sensors for breathing airflow monitoring. Measurement Science and Technology, 17(5), 1207.). From this, the waveform diagram reflecting the breathing behavior can be obtained. The amplitude of the waveform diagram reflects the relative value of the exhaled gas humidity, and also reflects the breathing amplitude. Fourier transform is performed on the waveform diagram to obtain the respiratory frequency and the breat...

Abstract

The invention relates to a flexible respiratory monitoring device and belongs to the fields of extendable flexible electronic devices and health monitoring. The flexible respiratory monitoring device is technically characterized in that a flexible respiratory monitoring sensor is utilized for monitoring a respiratory signal; the flexible respiratory monitoring device is directly and comfortably attached onto skin; a respiratory signal analysis module is utilized for acquisition, transmission, processing and feedback of the signal. The flexible respiratory monitoring device utilizes a system composed of the flexible respiratory monitoring sensor, the respiratory signal analysis module and an electrode to conformably and conveniently monitor respiratory behavior characteristics (frequency and amplitude) of a user, in particular to an apnea event; a mask, a nose plug and other physical supports are not needed, so that the negative effect of respiratory monitoring on the life quality of the user is reduced in a small scale, in a lightweight manner and to a maximum extent; a sensing function layer of the flexible respiratory monitoring sensor adopts a flexible extendable structure, and a biocompatible thin film is adopted as package and base layers, so that the safety and the comfort in the use process are ensured.

Description

technical field [0001] The invention relates to a flexible breathing monitoring device, which can be used but not limited to the detection of sleep-disordered breathing. Background technique [0002] Respiration is an activity of gas exchange between the human body and the outside world, and its frequency and depth are basic physiological indicators reflecting the health status of the human body. Sleep-disordered breathing is a disease in which breathing disorders such as apnea, shallow breathing, and irregular breathing occur during sleep. The direct consequence of apnea is excessive carbon dioxide in the body, decreased blood oxygen saturation, and decreased PH value in the body. If the apnea is not relieved for a long time, it may lead to permanent brain damage and even death. The latest interpretation rules of the American Academy of Sleep Medicine on respiratory events point out that the mouth and nose thermal sensor should be used to judge apnea. When the breathing de...
