Portable residual gas dispersion lung function tester

Abstract

The invention provides a portable residual gas diffusion lung function tester, which comprises a main machine, a gas diffusion module, a gas diffusion module, a gas diffusion module, a gas diffusion module, a gas diffusion module, a gas diffusion module, a gas diffusion module and a gas diffusion module, and is characterized in that the main machine is of a box-type structure; the power supply module, the sucking pump and the gas analyzer are all in circuit connection with the main control board; the testing gas cylinder is filled with high-pressure testing gas used for dispersing residual gas, and a pressure reducing device is arranged at an outlet of the testing gas cylinder; the first outlet end of the testing head is connected with the testing gas cylinder through a pipeline through the pressure reducing device, the second outlet end of the testing head is connected with the gas analyzer through a pipeline, and the testing head is in control connection with the main control board at the same time; the operation terminal is in control connection with the main control board; and the sucking pump is connected to the rear end of the gas analyzer through a pipeline. The equipment is convenient to move and carry, and can be used in high-altitude field environments such as plateau, and the applicability is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a portable diffused residual air lung function tester. Background technique [0002] Respiration provides oxygen for life activities, and external oxygen needs to undergo two processes of external respiration and internal respiration to combine with hemoglobin in the body. Among them, external respiration refers to the physical breathing movement of the lungs, the process of bringing fresh air from the outside into the alveoli. Internal respiration refers to the process in which oxygen in the alveoli diffuses from the alveoli to the capillaries through the alveolar-capillary membrane to reach the blood, and combines with the hemoglobin in the red blood cells. Therefore, clinical respiratory function tests include external breath determination (ie, ventilatory function test) and internal breath test (ie, diffusing residual gas test). External breath determination is rela...

Problems solved by technology

In addition, because the existing test equipment is generally laboratory equipment, the test requires a variety of gas analyzers, must work in a laboratory environment, and has strict requirements on the ambient atmospheric pressure, so it cannot be applied to tests in high altitude areas, even in Doesn't work correctly in lab environments at high altitudes
