Parallel inspiration and expiration breathing training device

Abstract

The invention provides a parallel inspiration and expiration breathing training device. The parallel inspiration and expiration breathing training device comprises an outer barrel, an outer screw sleeve and an end cover, wherein the outer screw sleeve is coaxially mounted in the outer barrel, a first air hole is formed in one end of the outer screw sleeve, a second air hole is formed in the otherend of the outer screw sleeve, a convex ring is arranged on the outer wall of the first air hole end of the outer screw sleeve, a third air hole is formed in the convex ring, a step is arranged at theposition, close to the second air hole, of the outer screw sleeve, so that the diameter of an inner cavity of the outer screw sleeve at the second air hole end is smaller than that at the first air hole end, one end of the outer barrel is mounted at one end of the convex ring of the outer screw sleeve through a first axial limiting device, so that the outer cylinder and the outer screw sleeve canrotate relative to each other, and the other end of the outer barrel is open. The parallel inspiration and expiration breathing training device is simple in structure and convenient to use, and can realize the inspiration training, inspiration training and mixed breathing training at the same time aiming at inspiration difficulty, expiration difficulty and mixed breathing difficulty, and meanwhile, the inspiration resistance and expiration resistance can be independently and continuously adjusted.

Description

technical field [0001] The present invention relates to a parallel type inhalation and exhalation respiratory trainer. Background technique [0002] With the aggravation of air pollution and the aging of the population structure, the prevalence of respiratory diseases has been increasing year by year, becoming a major issue affecting the public health of residents across the country. Respiratory diseases can easily lead to dyspnea, which can lead to hypoxia and induce heart and brain diseases. Different respiratory diseases can cause different dyspnea, and dyspnea caused by respiratory organ lesions manifests in three forms: inspiratory dyspnea caused by larynx and tracheal stenosis, and exhalation caused by bronchial asthma and obstructive lung disease Mixed dyspnea due to diseases such as chronic dyspnea, pneumonia, pulmonary fibrosis, and pneumothorax. [0003] In order to solve human breathing difficulties caused by respiratory diseases, on the one hand, active treatme...

AI Technical Summary

Problems solved by technology

The weak point of this type of breathing trainer: (1) need the columnar cylinder cavity that float is housed to be placed vertically when in use; (3) The adjustment of inhalation resistance is discontinuous; (4) Most of them are large in size and heavy in weight, so they are not easy to carry

In addition, there are a small number of products such as PowerBreathe breathing trainer, Shengchang SC-A breathing trainer, utility model patent 201520499638.4, etc. Although there is no body position requirement, they can only do inhalation training, and the structure is complicated
