Abstract

This utility model belongs to the field of medical device technology, specifically relating to an exercise device suitable for pulmonary function rehabilitation. Existing respiratory trainers mostly use corrugated air delivery tubes, which have many internal grooves, easily accumulating dirt and grime, making cleaning and disinfection difficult, and increasing the risk of cross-infection for pulmonary function rehabilitation patients. This device consists of a respiratory trainer body and an air delivery assembly. In the air delivery assembly, the first tube of the steering tube is sealed and inserted into the connecting tube of the trainer body, with a limiting structure ensuring stable connection; the second tube is tilted upwards and sealed to an axially sliding extension tube, allowing for height adjustment to meet the needs of different patients. The mouthpiece is detachably connected to the upper end of the extension tube. This device has a simple internal structure, is easy to clean and disinfect, and effectively reduces the risk of cross-infection; the sealing design between components ensures efficient and stable gas delivery; the tilted design of the second tube facilitates patient observation of the trainer body, providing a practical and reliable solution for pulmonary function rehabilitation training.
