Description

Improved structure of positive pressure respirator mask

technical field

The utility model relates to an improved structure of a positive pressure respirator mask, in particular to a CPAP mask which can separate air from carbon dioxide so that sleeping patients can breathe fresh air all the time.

Background technique

Continuous Positive Airway Pressure (CPAP) is used for patients with respiratory diseases. When the patient is sleeping, a continuous positive pressure airflow is sent into the patient's airway through a mask to prevent the patient from short-term breathing and cause shortness of breath. Oxygen poses a hazard. However, the commonly used CPAP mask has the defect that the patient exhales too much carbon dioxide and cannot be effectively eliminated in time, which often causes the patient to wake up suddenly, or seriously affects the quality of sleep due to insufficient oxygen content during breathing.

Utility model content

The utility model proposes in order to solve the above problems.

The main purpose of this utility model is to provide an improved structure of a positive pressure respirator mask. A diaphragm is installed in the CPAP mask, which can effectively separate the air from carbon dioxide. To the exhaust valve, when fresh air is input through the CPAP ventilator, part of the air will discharge the carbon dioxide discharged by the patient during breathing through the one-way exhaust valve, and the other part of the air will be absorbed by the patient during inhalation. The patient can breathe fresh air all the time in the CPAP mask. The improved structure of the positive pressure respirator mask includes:

A mask, with an upper cover on the top, and an air hole under the upper cover, and a one-way valve plate embedded in the air hole;

A diaphragm, connected to the inner side of the perforation of the mask, divides the inside of the mask into two air chambers, one end of which has a vent hole;

A forehead fixing seat, which is installed above the mask, has a positioning groove on both sides of the center, and positioning holes in different positions in the positioning groove;

One fixed liner, the front edge has two buckles, the buckles are fastened in the positioning groove of the forehead fixing seat, and the positioning holes at different positions in the positioning groove are determined by the buckle buckle according to the width of the patient's forehead.

The utility model has the advantages of simple structure and convenient use, and can make sleeping patients breathe fresh air all the time, so as to prevent too much CO ₂ from being sucked, affecting the quality of sleep or causing hypoxia.

Detailed ways

The specific embodiment of the utility model is described below in conjunction with accompanying drawing:

Fig. 1, Fig. 2 and Fig. 3 are appearance diagram, exploded view and sectional view of the present utility model respectively, as shown in Fig. 1 to Fig. 3, the improved structure of positive pressure respirator face shield described in the present utility model comprises face shield 10, Diaphragm 20, fixing ring 30, silicone lining 40, forehead fixing seat 50, fixing lining 60, swivel head 70, connecting pipe 80, pipeline joint 90 and other components.

Wherein, there is a perforation 11 on the front side of the bottom of the mask 10, and a buckle 12 is respectively arranged on both sides of the perforation 11. A belt buckle 13 can be inserted in the buckle 12, and a strap (not shown) can be tied on the buckle 13. The top has An upper cover 14, the lower end of the upper cover 14 has an air hole 15, the air hole 15 is embedded with a one-way valve plate 16, and the air port 17 at the bottom of the perforation 11 can be plugged with a plug 18.

The soft diaphragm 20 is connected to the inside of the perforation 11 of the mask 10, and the mask 10 is divided into upper and lower two air chambers A, B (as shown in FIG. 3 ), and one end has a vent 21.

The ring buckle 31 on the front edge of the fixing ring 30 can be fastened in the button hole 19 of the mask 10 .

The silicone lining 40 has a lining hole 41 on its front side for one end of the fixing ring 30 to be embedded.

The forehead fixing seat 50 is provided with an angle adjuster 51 at its bottom, and the clamping blocks 511 on both sides of the angle adjuster 51 are fixed in the clamping holes 141 of the upper cover 14 of the mask 10, and the buckle seats 52 on both sides can be plugged in respectively. There is a buckle 53 on which a strap (not shown) can be bound, and a positioning groove 54 is respectively arranged on both sides of its center, and positioning holes of different positions are arranged in the positioning groove 54 .

The fixed liner 60 has two buckles 61 on its front edge, the buckles 61 are fastened in the positioning groove 54 of the forehead fixing seat 50, and the buckles 61 can be fixed in different positions in the positioning groove 54 according to the width of the patient's forehead in the positioning hole.
