Rebreathing apparatus

Abstract

The invention discloses a rebreathing apparatus, comprising a breathing unit, a gas connecting tube, a gas inlet tube, a gas storage box, a regulator and a master controller; the breathing unit coversthe user's face and particularly covers user's mouth and nose, and is connected with the first end of the gas inlet tube through the gas connecting tube; a gas storage port and a feed-through port are formed at the second end of the gas inlet tube; the gas inlet tube is communicated to the external air through the feed-through port, and is communicated into the gas storage box through the gas storage port; the gas storage box is used for gas breathed out by the user; the regulator is arranged at the second end of the gas inlet tube and receives a regulating signal of the master controller, and regulates openness of the gas storage port and the feed-through port according to the regulating signal of the master controller. The level of carbon dioxide of the patient can be increased by meansof rebreathing, the breathing state of the patient can be improved effectively when the patient is sleeping, sleep apnea is avoided, and the comfort level of the apparatus to users is increased.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a rebreathing device. Background technique [0002] Sleep apnea syndrome (SAS) is a common sleep-disordered breathing disorder. According to recent global epidemiological studies, 15-20% of adults and 5-10% of children suffer from sleep-disordered breathing. According to statistics, the incidence of SAS is about 7%, and with the aging of the population and the increasing degree of obesity, the incidence of SAS tends to increase year by year. Repeated apnea can cause nocturnal hypoxia and hypercapnia, and lead to complications such as hypertension, coronary heart disease, diabetes and cerebrovascular disease, traffic accidents, and even sudden death at night. SAS has become a major disease threatening human public health. However, except for continuous positive airway pressure (CPAP) and partial surgical treatment, there is no other good clinical treatment. [0003] Continuous ...
