Description

Technical Field

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

[0002] Preoperative rehabilitation for patients undergoing thoracic surgery is particularly important, especially preoperative respiratory function training. Since atelectasis and respiratory insufficiency are common respiratory complications after thoracic surgery (e.g., lung cancer surgery), they are often prevented by preoperative abdominal breathing training in clinical practice, which usually starts one to two weeks before surgery. Abdominal breathing training is an exercise method that improves breathing depth by regulating diaphragmatic movement. However, in the process of implementing abdominal respiratory function training (especially during the period of home prehabilitation from outpatient diagnosis to hospitalization for surgery), the following problems may still exist: 1. During home prehabilitation, it is difficult for patients to implement standardized rehabilitation measures and lack timely and effective guidance. For example, the training methods are not standardized, such as the rhythm and depth of inhalation and exhalation are not well mastered, resulting in poor training results; the training intensity is difficult to grasp, for example, the training intensity is too high or the time is too long, resulting in patient fatigue. 2. Individual differences in patients and different degrees of lung function damage lead to different responses of patients to training intensity and time, and it is difficult for patients to judge and make reasonable adjustments. 3. There is a lack of communication channels between doctors and patients, a lack of guidance, supervision and motivation from medical staff, and a lack of real-time communication and feedback with medical staff. Patient training compliance is often low.

[0003] At present, the 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 all have certain limitations: hand position detection and visual observation are highly subjective and may interfere with breathing; respiratory rate detection ignores the quality of breathing and the data is single; body reaction detection is interfered by other factors and is difficult to quantify; professional equipment detection is costly and complicated to operate; self-feeling detection relies on personal experience and is prone to misjudgment.

[0004] Currently, there is still a lack of such a dedicated training assistance system for preoperative abdominal breathing training for thoracic surgery patients. This equipment should not only be able to collect, transmit and analyze the real-time data of patients during breathing training, but also be able to automatically and objectively evaluate the patient's training method to overcome the inaccuracy of the patient's self-perception and oral description, so as to better assist the patient's abdominal breathing training and achieve good training results.

[0066] According to the chest breathing movement monitoring signal, the abdominal breathing movement monitoring signal, the mouth exhalation airflow monitoring signal, and the nasal inhalation airflow monitoring signal during the abdominal breathing trainee's practice phase, standard breathing movement characteristic data of the abdominal breathing trainee are obtained;

[0067] The chest respiratory movement monitoring signal, abdominal respiratory movement monitoring signal, oral expiratory airflow monitoring signal and nasal inspiratory airflow monitoring signal of the abdominal breathing trainees during the training stage are compared with the standard respiratory movement characteristic data, and the abdominal breathing training evaluation results of the abdominal breathing trainees are obtained through preset judgment conditions.
