Abstract

The invention provides a breathing control device and breathing mask equipment with the same. The breathing control device comprises a cavity, and one or more valve components, wherein one or more gas conveying openings as well as a mask vent communicated with a breathing mask are formed in the cavity; the valve components are arranged in one or more of the gas conveying openings, matched with the gas conveying openings to form a gas inlet and a gas outlet, and used for communicating the gas inlet with the mask vent when pressure in the cavity is lower than or equal to the atmosphere, and communicating the gas outlet with the mask vent when the pressure in the cavity is higher than the atmosphere; the cross section area of the gas inlet is larger than that of the gas outlet; the gas outlet is used for keeping the pressure in the cavity to be higher than the atmosphere when a patient expires. The breathing control device has the advantages that the positive pressure function of an expiring phase is realized, so as to avoid discomfort of the patient caused by continuous positive pressure; during use, the breathing control device and the breathing mask equipment are not required to be connected with a positive pressure gas supply device, pipeline and the like, so that the patient can move conveniently, and needs not to carry the positive pressure gas supply device while going out.

Description

technical field [0001] The invention relates to the technical field of breathing masks, in particular to a ventilation control device for a breathing mask and a breathing mask equipment with the ventilation control device. Background technique [0002] At present, the methods for treating obstructive sleep apnea-hypopnea syndrome (OSAHS) mainly include surgery, oral appliance and continuous positive airway pressure (CPAP). [0003] The most commonly used surgical method is uvulopalatopharyngoplasty and its modified operation, which is used for upper airway oropharynx obstruction (including hypertrophy of pharyngeal mucosal tissue, narrow pharyngeal cavity, uvula hypertrophy, low soft palate, tonsil hypertrophy) ) and apnea-hypopnea index (AHI) <20 times / hour. Due to the need for surgery, this method has low patient acceptance, and no matter how long the surgical tissue is, it will cause recurrence of the disease, and it is impossible to perform another operation afterwar...
