Lung function recovery training device

Abstract

The invention discloses a lung function recovery training device which comprises a piston cylinder, a piston, a piston rod and a self-adjusting resistance-increasing mechanism, the piston is in sliding sealing fit in the piston cylinder, the piston rod is fixedly connected to the second end of the piston, the self-adjusting resistance-increasing mechanism is fixedly installed on the outer wall of the piston cylinder, and the self-adjusting resistance-increasing mechanism is fixedly connected to the second end of the piston. The self-adjusting resistance-increasing mechanism is arranged in parallel with the piston cylinder, two or more air outlet holes are distributed in the cylinder wall of the piston cylinder in the axial direction of the piston cylinder, and the air outlet holes are in fluid communication with resistance-increasing assemblies, with different resistances, of the self-adjusting resistance-increasing mechanism through pipelines. By arranging a piston, a piston barrel and a spring, the lowest resistance can be provided for a user, the training requirement of a patient with poor respiratory capacity is met, by arranging a first-stage resistance increasing barrel, gas is introduced into a resistance increasing airbag on a first movable plate to expand, so that the resistance increasing airbag is attached to the inner wall of the first-stage resistance increasing barrel, and the advancing resistance of a piston rod is increased; the training intensity is automatically improved.

Description

technical field [0001] The present invention relates to the technical field of lung training. Specifically, it is a pulmonary function recovery training device. Background technique [0002] When people breathe normally, they need the coordination and cooperation of multiple muscles in the human body. When a patient with lung disease is cured, it is necessary to perform lung rehabilitation training to promote lung rehabilitation. [0003] Most of the existing rehabilitation training devices are bulky and inconvenient to carry. Secondly, the training intensity of the training device needs to be manually adjusted, which is inconvenient, and one adjustment is often unable to accurately adjust to the appropriate training intensity, resulting in a change in the training effect. In a rehabilitation training, as the training progresses, the patient's physical fitness gradually declines, and continuous manual adjustment is required, which brings more inconvenience. SUMMARY OF THE...

Problems solved by technology

[0003] Most of the existing rehabilitation training devices are large in size and not easy to carry. Secondly, the training intensity of the training device needs to be manually adjusted, which is inconvenient. However, one adjustment often cannot accurately adjust to the appropriate training intensity, resulting in a change in the training effect. Poor, it needs to be adjusted many times. In a rehabilitation training, as the training progresses, the patient's physical fitness gradually declines, and continuous manual adjustments are required, which brings more inconvenience.
