Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical data processing, and in particular to an abdominal breathing training auxiliary system. BACKGROUND

[0002] Preoperative rehabilitation of thoracic surgery patients is particularly important, especially preoperative respiratory function training. Because atelectasis and respiratory insufficiency are common respiratory complications after thoracic surgery (e.g., lung cancer surgery), preoperative abdominal breathing training is often used to prevent them, usually starting one to two weeks before surgery. Abdominal breathing training is an exercise method that improves breathing depth by regulating diaphragmatic movement. However, there are still some problems in the process of implementing abdominal breathing function training (especially during home rehabilitation from outpatient diagnosis to hospital surgery): 1. Patients have difficulty performing standardized rehabilitation measures during home rehabilitation, and lack timely and effective guidance. For example, the training method is not standardized, such as difficulty in mastering the rhythm and depth of inhalation and exhalation, resulting in poor training effect; it is difficult to grasp the training intensity, such as excessive training intensity or excessive training time leading to patient fatigue, etc. 2. Individual differences and varying degrees of lung function impairment in patients result in different patient responses to training intensity and time, and patients themselves have difficulty in judging and reasonably adjusting. 3. Lack of doctor-patient communication port, lack of guidance, supervision and motivation from medical staff, and lack of real-time communication and feedback with medical staff, resulting in low patient training compliance.

[0003] Currently, methods for detecting the effect of abdominal breathing training include hand position detection, visual observation, respiratory rate detection, body reaction detection, professional equipment detection, and self-feeling detection. However, these methods have certain limitations: hand position detection and visual observation are highly subjective and may interfere with breathing; respiratory rate detection ignores breathing quality and provides only single data; body reaction detection is disturbed by other factors and is difficult to quantify; professional equipment detection is costly and complex to operate; and self-feeling detection relies on personal experience and is prone to misjudgment.

[0004] Currently, there is a lack of a dedicated training auxiliary system for preoperative abdominal breathing training of thoracic surgery patients. Such a device should not only be able to collect, transmit, and analyze real-time data of patients during the breathing training process, but also be able to automatically and objectively evaluate the training method of the patient, in order to overcome the inaccuracy of patient self-feeling and verbal description, and thus better assist the patient in abdominal breathing training and achieve good training results.
