Description

Breath exercise device Technical Field The invention relates to the technical field of medical appliances, in particular to a respiratory exercise device. Background In the field of respiratory rehabilitation therapy, there is a class of devices for respiratory exercises of patients designed to allow the user to take a repeat breath through a closed or semi-closed system of pipes, and generally equipped with visual movements and scales to indicate the volume of a single breath. The core function of such devices is to assist the patient in exercising the respiratory muscle groups by providing a controlled respiratory resistance or target volume. However, this type of device has some problems in use, and when the user continues to breathe, the exhaled gas will re-enter the device system and circulate with the gas mixture that remains therein. This process inevitably results in a gradual build-up of carbon dioxide content in the gaseous environment inside the device, with a corresponding decrease in oxygen concentration. The use of such a closed cycle mode for a long period of time may cause insufficient oxygen to be inhaled by the user, thereby posing a potential risk. To cope with this drawback, there are two common solutions, one of which is to strictly limit the time of single continuous use, and only meet the extremely short respiratory training requirement, which severely restricts the continuity and effect of training, and the other is to provide auxiliary inhalation holes on the device pipeline, so that the outside air can partially infiltrate during the respiratory process to dilute the carbon dioxide in the system and supplement oxygen. However, when the outside air is introduced, the tightness of the breathing circuit is also damaged, so that the capacity calculation is deviated, only rough estimation of the breathing capacity can be realized, and the measurement accuracy is greatly reduced. To this end, a respiratory exercise apparatus is provided that solves the above-mentioned problems.
