Abstract

Provided are a ventilation control device and breathing mask equipment with the same. The ventilation control device comprises a cavity, an air inlet valve and an air outlet valve; the cavity is provided with an air inlet, an air outlet and a mask vent opening, and the mask vent opening is used for being ventilated with a breathing mask; the air inlet valve is arranged at the air inlet, and when the pressure in the cavity is smaller than or equal to the atmospheric pressure, the air inlet valve is opened; the air outlet valve is arranged at the air outlet, and when the difference of the pressure in the cavity and the atmospheric pressure is larger than or equal to the first preset value, the air outlet value is opened. By means of the ventilation control device, the positive pressure function of the expiratory phase is achieved, and the discomfort caused by continuous positive pressure to a patient is avoided; the ventilation control device does not need to be connected with a positive pressure gas supply device such as a CPAP respirator, a pipeline and the like in use, and the patient can move conveniently; when the patient goes out, the patent does not need to carry the positive pressure gas supply device, and the patient can wear the breathing mask equipment with the ventilation control device to conduct treatment at any time. In addition, 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] 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...
