rebreathing device

Abstract

The invention discloses a rebreathing device. Including: breathing device, gas connecting pipe, intake pipe, gas storage tank, regulating device and main controller; the breathing device is covered on the user's face to cover the mouth and nose of the user; the breathing device is connected to the intake pipe through the gas connecting pipe The first end of the air inlet pipe; the second end of the air intake pipe is provided with two air outlets: an air storage port and a straight-through port; the air intake pipe leads to the external air of the rebreathing device through the straight-through port; the air intake pipe leads to the air storage tank through the air storage port; The air box is used to store the gas exhaled by the user; the regulating device is located at the second end of the intake pipe; the regulating device receives the regulating signal of the main controller, and adjusts the opening of the gas storage port and the straight-through port according to the regulating signal of the main controller. The invention utilizes self-rebreathing to increase the carbon dioxide level of the patient, effectively improves the breathing state of the patient in the sleep state, eliminates sleep apnea, and improves the user's comfort.

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 ...
