Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a breathing trainer. Background Art

[0002] A respiratory trainer, also known as a breathing trainer, is mainly used in medicine to help patients who have undergone abdominal or thoracic surgery improve their breathing depth and duration. A respiratory trainer can be divided into a three-ball device or a single-ball device according to its structure. It is mainly composed of a folded hose, an inhalation port, a fixing frame, a filter and a resistance ball. The folded hose is made of polystyrene, the inhalation port is made of plastic, the fixing frame is made of polystyrene, the filter is made of polyurethane, and the resistance ball is made of ABS.

[0003] There are already some breathing trainers on the market. For example, a Chinese patent with authorization announcement number CN205235290U and publication date of May 18, 2016 discloses a breathing trainer, which includes: a plurality of vertical cavities arranged side by side, piston balls and suction pipes respectively arranged in each cavity; the top of each cavity is connected to the main airway through a suction hole, and the bottom is respectively provided with ventilation holes connected to the outside; an adjustment plate is respectively provided at each ventilation hole to adjust the opening of the ventilation hole; an intake port is provided on the main airway, and the intake port is connected to the intake pipe in a detachable manner, preferably by a threaded connection; the application can adjust the opening of the ventilation hole by adjusting a movable adjustment plate at the ventilation hole and adjusting the step angle of the ventilation plate, thereby adjusting the suction force to adapt to the training difficulty of different people and better meet the training needs of the user.

[0004] Regarding the above-mentioned technology, the inventor believes that the adjustment plates provided at multiple ventilation holes in the application will greatly increase the suction pressure compared with traditional products, resulting in poor use effect; at the same time, when adjusting the opening of the ventilation holes, changing the suction pressure will also cause the pressure of the air entering the cavity to increase, thereby affecting the rise of the piston ball. In actual operation, it is difficult to stably control the adjustment range, which is inconvenient to use. Utility Model Content
