Postoperative lung rehabilitation training device for cardiothoracic surgery

Abstract

The invention relates to the field of medical rehabilitation instruments. The cardiothoracic surgery postoperative lung rehabilitation training device comprises a cylindrical shell, a bent pipe is arranged at the top of the shell, one end of the bent pipe is communicated with the top of the shell, and the other end of the bent pipe is connected with an air blowing nozzle; a transverse partition plate is fixedly arranged in the middle of the interior of the shell and divides the shell into an expiration chamber located on the upper portion and a buoyancy driving chamber located on the lower portion. A first lifting cap is arranged in the expiration chamber, the first lifting cap is in a cylinder shape with the upper end open and the lower end closed, the first lifting cap and the expiration chamber form vertical sliding fit, and sealing is formed between the side wall of the first lifting cap and the side wall of the expiration chamber. Expiration impedance is constructed through buoyancy, the stability of the expiration impedance can be guaranteed, and meanwhile the device is small in structure and convenient to carry.

Description

technical field [0001] The invention relates to the field of medical rehabilitation equipment, in particular to a pulmonary rehabilitation training device after cardiothoracic surgery. Background technique [0002] In the actual working process of cardiothoracic surgery, in order to assist the recovery of lung function after the patient has completed the surgical treatment, in addition to drug treatment, it is often necessary to cooperate with certain physical therapy. One of the common ways is to improve the function of the respiratory muscles by increasing the expiratory resistance. In terms of increasing the resistance to exhalation, the commonly used method in the prior art is to use springs to resist resistance. When the exhalation pressure reaches a level sufficient to overcome the spring force, the air outlet of the instrument is turned on to realize exhalation; If the air pressure is not enough to overcome the spring force, the air outlet of the device will be close...

Problems solved by technology

This causes the impedance it can provide to fluctuate, making accurate settings impossible. For patients in the middle and late stages of rehabilitation, this fluctuation blocking has little impact on rehabilitation training. However, for patients in the early stage of rehabilitation, due to physical Relatively weak, this kind of fluctuating impedance is not conducive to the precise formulation of treatment plans, and has a greater adverse effect on treatment

For this reason, in the prior art, there is also a solution to provide expiratory resistance through counterweights. However, most of these counterweight rehabilitation devices are complex in structure and bulky, and are not easy to carry.
