Problems solved by technology

However, since the respiratory signal is a low-frequency signal, it is easily affected by factors such as heart beating, blood flow, and motion interference. Among them, the impact of motion headroom caused by body motion is particularly significant, which will affect the accuracy of the calculation of the respiratory frequency value

Abstract

The invention provides a wearable respiration measurement device and a respiration measurement method. The wearable respiration measurement device comprises a respiration sensor and a chest belt connected with the respiration sensor, wherein the chest belt is used for binding the respiration sensor onto the chest of a user; the respiration sensor is composed of a packaging case and a pressure detecting unit arranged inside the packaging case; the pressure detecting unit is composed of a substrate, a piezoelectric sensing element, a single processing device, a pressing unit and a first deformation piece. Through the micro-pressure model technology, the wearable respiration measurement device can convert tension generated by the chest during respiration into transverse force perpendicular tothe chest, and by precisely collecting micro pressure sensors, can obtain precise respiration frequency and amplitude through circuit processing.

Description

technical field [0001] The invention relates to the technical field of wearable equipment and the technical field of physiological parameter measurement, in particular to a wearable respiration measurement device and a respiration measurement method. Background technique [0002] The existing respiratory frequency measurement methods include differential pressure airflow detection method, thermal element detection method, biological impedance detection method and so on. [0003] The principle of the differential pressure airflow detection method to measure the respiratory frequency is that when the human body is exhaling and inhaling, the pressure in the airtight breathing mask worn at the nostrils will change, and the air pressure sensor converts the pressure change into a voltage signal. Change output, the respiratory rate is obtained by identifying the change of the voltage signal. This method requires that the breathing mask worn at the nostril must be airtight, and som...
