Vital capacity automatic detection and exercise equipment for respiratory medicine department

Abstract

The invention discloses vital capacity automatic detection and exercise equipment for the respiratory medicine department. The vital capacity automatic detection and exercise equipment comprises a bottom plate; the upper surface of the bottom plate is fixedly connected with a sealing fence; piston rings are slidably connected to the inner wall of the sealing fence in an up-down limiting mode, and water storage bottles with downward bottle openings are arranged on the inner walls of the piston rings. Piston plates are slidably connected to the inner wall of the water storage bottle in an up-and-down limiting mode, a through hole is formed in the upper surface of the water storage bottle, and an air blowing pipe is fixedly connected to the upper surface of the water storage bottle through the through hole; the lower space of the water storage bottle and the lower space of the sealing fence are filled with replacement liquid, and the upper surface of the piston ring is fixedly connected with a cylinder. The side face of the cylinder is fixedly connected with a protruding block. Through cooperative use of the structures, the invention can solve the problems that in the actual use process, due to the fact that a traditional device is single in effect and difficult to carry out regular detection when used for detecting the vital capacity, and an existing vital capacity detection device is difficult to use for exercise the vital capacity.

Description

technical field

[0001] The invention relates to the technical field of medical equipment, in particular to an automatic lung capacity detection and exercise equipment for respiratory medicine. Background technique

[0002] Vital capacity is the volume of air that can be exhaled as hard as possible after maximal inhalation. It includes three parts: tidal volume, inspiratory supplementary volume and expiratory supplementary volume. Tidal volume refers to the volume of air inhaled or exhaled by the lungs in one breathing cycle. The maximum volume of air inhaled in addition to the tidal volume is the inspiratory volume, and the maximum volume of air exhaled outside the tidal volume is the expiratory volume. The residual volume is the volume of air remaining in the lungs. There are large individual differences. It is affected by factors such as age, sex, body size, strength of respiratory muscles, and elasticity of the lung and thorax. Generally speaking, the stronger the bod...
