It is a medical device designed for rehabilitation training after thoracic surgery, which can assist patients with deep breathing and cough training so as to restore the physiological function of the lung. Due to the pain of postoperative wounds, many patients, especially elderly patients, will resist rehabilitation training. This device is designed to assist the training and alleviate the pain during it while combining fun to ease psychological discomfort.
