Convenient vital capacity rehabilitation training device for respiratory medicine department

Abstract

The invention discloses a convenient vital capacity rehabilitation training device for the respiratory medicine department. The device comprises an expiration cover, a metering end shell, a screw core, a balance weight disc, an air blowing cushion shell, an inserting opening, a filter element fixing disc, filter element cotton, activated carbon and a water dissolving layer, the metering end shellis arranged at the front end of the expiration cover, a display screen is arranged on the upper surface of the metering end shell, a connecting ring is connected to the front end of the metering end shell, a training end shell is installed at the front end of the connecting ring, the filter element fixing disc is fixed to the tail end of the rear side of the filter element shell, the filter element cotton is arranged on the inner side of the filter element shell, the activated carbon is arranged on the front side of the filter element cotton, and the water dissolving layer is installed on thefront side of the activated carbon. Through the training end shell and an anti-skid rubber pad, the surface of a rubber material is subjected to groove processing, the rubber material can be attachedto fingers more easily, the anti-skid effect is achieved, a detachable fixed ring and the training end shell are arranged, and the whole body can be separated to facilitate cleaning of internal structures through a threaded structure detaching mode.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training devices, in particular to a convenient vital capacity rehabilitation training device for respiratory medicine. Background technique [0002] Vital capacity is the volume of air that can be exhaled 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. Lung capacity is closely related to human breat...

Problems solved by technology

[0004] The purpose of the present invention is to provide a convenient lung capacity rehabilitation training device for respiratory medicine, which solves the problem that the replacement cost of the existing respiratory port contact parts is relatively high, and the training time is controlled by the user. The use efficiency and actual effect are low. The overall structure cannot be disassembled to clean and maintain the interior. The overall volume cannot be changed. The portability is poor, and the training effect cannot be reflected. It needs to be tested separately. If it is used for too long, water vapor will easily condense on the inner wall, which is not convenient for training. Questions with different adjustment difficulty levels
