Description

Technical Field

[0001] The present invention relates to the technical field of lung function detection, and in particular to a portable lung function detector and a working method thereof. Background Art

[0002] Appropriate exercise can speed up the patient's physical recovery, but excessive exercise or insufficient exercise will affect the patient's health. Patients with lung disease need to monitor their breathing data at all times during exercise to determine whether the intensity of the rehabilitation exercise is appropriate. Doctors intervene in the patient's rehabilitation exercise based on the patient's breathing data during exercise, which helps the patient's physical recovery.

[0003] The pulmonary function testers in the prior art are complex in structure and inconvenient to carry. They are not equipped with anti-drop and sealed breathing masks for patients in motion, which makes it impossible for the traditional pulmonary function testers to cooperate with patients in motion to monitor their breathing. At the same time, the pulmonary function testers in the prior art usually adopt the basic principle of impedance training. When patients use the pulmonary function testers in the prior art to perform breathing training, they need to work hard to resist the impedance set by the device to increase the inspiratory muscle strength, thereby increasing the strength and tolerance of the respiratory muscles. However, the lung function status of different users or the same user at different times may be different. The existing pulmonary function testers usually set the impedance based on experience, and the procedure for setting the impedance is complicated. Elderly patients do not understand how to operate it at all, which often leads to ineffective breathing training results. Summary of the invention
