Abstract

The invention relates to a ventilation control device and breathing mask equipment with the same. The ventilation control device comprises a cavity, a valve assembly and a silencer, wherein the cavity is provided with one or more air conveying openings and a mask ventilating opening, the air conveying openings are communicated with the mask ventilating opening, and the mask ventilating opening is used for being communicated with a breathing mask; the valve assembly is arranged at least one of the air conveying openings and structured in the mode of keeping the pressure in the cavity higher than barometric pressure in the expiration process; the silencer comprises multiple silencing holes, and the multiple silencing holes are communicated with at least one of the air conveying openings so that air can enter the air conveying openings through the silencing holes and/or air exhausted by the air conveying openings can be exhausted through the silencing holes. The positive pressure function of the expiratory phase is achieved by the ventilation control device, and discomfort, caused by continuous positive pressure, of a patient is avoided; it is unnecessary to connect a positive pressure gas supply device or a pipeline, and therefore the patient can move conveniently; it is unnecessary to carry the positive pressure gas supply device when the patient goes out. The ventilation control device is small in size, convenient to carry and low in cost.

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] Currently, the methods for treating obstructive sleep apnea-hypopnea syndrome (OSAHS) mainly include surgery, oral appliance, continuous positive airway pressure (CPAP) and positive end-expiratory pressure (PEEP) treatment. [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 i...
