Abstract

The invention provides a miniaturized low-power consumption breath mechanical parameter test device, which comprises a data acquisition unit and a data processing and display unit. In the test device, a combined type air flow-air pressure sensor which integrates an air flow-pressure test is designed according to two basic parameters of air flow and air pressure in breath mechanical parameters, sothat the pressure and the air flow can be measured simultaneously; related signals are acquired in a mode of weak capacitance detection mode, so the volume and power consumption of the device are reduced; and the signals of the breath mechanical parameters are acquired by combining with a signal amplifying circuit, an analog / digital (A / D) digital-to-analogue conversion circuit, a data acquisitioncircuit, a breath mechanical parameter computing unit, a liquid crystal display (LCD) display and the like, so that the acquisition, amplification and calculation of the breath mechanical parameters are realized. By the miniaturized low-power consumption breath mechanical parameter test device, the requirements of low power consumption and small volume are met, the real-time online detection of the breath mechanical parameters also can be realized, and the portable requirement is met.

Description

technical field [0001] The invention relates to a device for testing respiratory mechanical parameters, which belongs to the technical field of physiological parameter index testing in biomedical research. Background technique [0002] Respiration is the general process of gas exchange between the human body and the external environment. Respiratory Mechanics studies the mechanical problems of the respiratory system from the viewpoint and method of engineering. The study of respiratory mechanics is hoped to contribute to the understanding of respiratory physiology, and then to monitor the state of the human body. Respiratory mechanics parameters are important physiological parameters for evaluating lung function, and then evaluating respiratory function and human state. Therefore, the measurement of respiratory mechanical parameters plays an important role in the research and evaluation of lung function. Respiratory mechanics testing is different from pulmonary function t...
