Abstract

A CPAP mask, within which is disposed a membrane that effectively separates air and carbon dioxide within a face mask into two air chambers, and a one-way air escape valve plate is fitted to an air vent at one end of the face mask. Accordingly, when air is input into the CPAP mask through a CPAP (Continuous Positive Airway Pressure) ventilator, one portion of the air expels the CO₂ exhaled by the patient through the one-way air escape valve plate, while the other portion of the air is inhaled by the patient, thereby enabling the patient to inhale fresh air with each respiration.

Claims

1. A CPAP mask, comprising:

a face mask, a top end of the face mask is provided with an upper cover, a lower portion of the upper cover is provided with an air vent, and a one-way valve plate is embedded in the air vent;

a membrane, the membrane is connected to an inner side of a through hole of the face mask, thereby separating the face mask into two air chambers, and one end of the membrane is provided with a vent outlet;

a forehead fixing mount installed to an upper portion of the face mask, two sides of a center of the forehead fixing mount are respectively provided with a position fixing slot, and the position fixing slots are Internally provided with different positioned position fixing holes;

a fixed lining, a front edge of the fixed lining is provided with two fastening clasps, and the fastening clasps are respectively fixedly clasped into the position fixing slots of the forehead fixing mount, fixedly clasping of the fastening clasps into the different positioned position fixing holes within the position fixing slots is determined according to the width of the forehead a patient.

2. The CPAP mask in accordance with claim 1, wherein a front side of a bottom portion of the face mask is provided with the through hole, and a rotating head is connected within the through hole;

the rotating head is connected to a pipe attachment and, the pipe attachment is connected to a CPAP (Continuous Positive Airway Pressure) ventilator.

3. The CPAP mask in accordance with claim 1, wherein the face mask is provided with clamping holes to enable clasps of a fixing ring to fixedly clasp therein, and a silica gel lining is fixed to the fixing ring.

4. The CPAP mask in accordance with claim 1, wherein clamping holes of the upper cover of the face mask enable clamping pieces of an angle adjuster at a bottom portion of the forehead fixing mount to fixedly clamp therein.

5. The CPAP mask in accordance with claim 1, wherein two sides of the through hole are respectively provided with a fastening mount to enable belt fasteners to be inserted therein.

6. The CPAP mask in accordance with claim 1, wherein two sides of the forehead fixing mount are respectively provided with a fastening mount to enable belt fasteners to be inserted therein.
