Technical Field

[0001] The utility model relates to a medical device, in particular to a breathing trainer for lung cancer patients. Background Art

[0002] Lung cancer is one of the common malignant tumors in my country. Surgery is currently an effective measure to treat lung cancer. Surgical trauma will affect the patient's lung function. The patient may experience symptoms such as chest tightness, cough, and difficulty breathing after surgery, which will affect the patient's quality of life. The respiratory function of lung cancer patients is significantly reduced after surgery. Coupled with the pain in the incision after surgery, patients often dare not cough or cough ineffectively, which can easily lead to atelectasis and aspiration pneumonia, thereby affecting lung function. Therefore, respiratory function exercises are needed before and after surgery.

[0003] At present, the Chinese patent with the announcement number CN213131808U discloses a breathing trainer, which includes a first airway shell and a second airway shell. The first airway shell and the second airway shell are symmetrically assembled. A socket is provided at the bottom of the second airway shell, and a suction nozzle is inserted into the socket. The suction nozzle and the first airway are connected by a hose. Small balls are provided in the first airway shell and the second airway shell. Respiratory rehabilitation training is completed by inhaling into the suction nozzle.
