Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to a positive pressure breathing mask. Background Art

[0002] A respiratory mask is a medical device, usually made of soft material, that covers the patient's mouth and nose to provide oxygen or other respiratory support. It is widely used in medical places such as emergency, operating rooms, and ICUs to help patients breathe or maintain respiratory function.

[0003] Existing positive pressure breathing masks are usually put on the head of a person through a strap, so that the mask body covers the patient's mouth and nose, and then the trachea is inserted into the air inlet pipe on the mask body for assembly, and then oxygen is supplied to the mask body through the trachea to help the patient breathe.

[0004] However, since oxygen will generate a certain amount of pressure on the trachea during the process of being transported through the trachea, the trachea may be displaced away from the intake pipe under the pressure, causing the connection between the trachea and the intake pipe to loosen and separate from the intake pipe, affecting the normal oxygen supply.

[0015] The effects achieved by the above components are: by providing the support plate, the support plate can increase the strength of the frame, reduce the deformation or bulge of the frame when subjected to force, and improve the stability of the frame.

[0016] Preferably, the connecting device includes a rectangular tube, which is fixedly connected to the air intake pipe, a second threaded hole is opened on one side of the rectangular tube, and a bolt is threadedly connected to the inner wall of the second threaded hole.

The trachea is located inside the frame 31 and between the two clamping plates 36. At this time, the two screws 35 are manually rotated to make the two screws 35 move toward each other along the two first threaded holes 32 respectively, so that the two screws 35 drive the two clamping plates 36 to move toward each other. When the two clamping plates 36 move toward each other and squeeze the surface of the trachea at the same time, the two clamping plates 36 clamp and limit the trachea, completing the reinforcement of the trachea, reducing the pressure and displacement of the trachea when delivering oxygen to the mask body 1, causing the connection between the trachea and the air inlet pipe 2 to loosen, causing the trachea to detach from the inside of the air inlet pipe 2 and affect the oxygen supply, thereby improving the stability of the connection between the trachea and the air inlet pipe 2.

[0030] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that the adjacent sides of the two splints 36 are fixedly connected with multiple rubber strips 37, and the multiple rubber strips 37 are arranged at equal distances. By setting the rubber strips 37, the rubber strips 37 can increase the resistance and fit between the splints 36 and the surface of the trachea, reduce the sliding of the trachea when the splints 36 clamp and limit the trachea, and further improve the limiting effect of the trachea. The ends of the two screws 35 away from the splints 36 are fixedly connected with a screw block 39, and the surfaces of the two screw blocks 39 are provided with multiple grooves. By setting the screw block 39, the screw block 39 can increase the contact area between the hand and the screw 35, so that the person can drive the screw 35 to rotate conveniently by manually turning the screw block 39.
