Description

Technical Field

[0001] The utility model relates to the technical field of oxygen cylinders, in particular to a portable emergency breathing assist device. Background Art

[0002] A portable oxygen cylinder is an oxygen cylinder that can be carried with you. It compresses oxygen into the tank through a pressurizing instrument, forming a small device with the characteristics of small size, large capacity, easy to carry, and high pure oxygen concentration. Generally speaking, portable oxygen cylinders are filled with oxygen with a purity of more than 95%, which is convenient for people to use for emergency treatment and daily health care. For example, after long hours of work or intense physical exertion, you can use a portable oxygen cylinder to replenish oxygen, so that the body can replenish energy through oxygen and restore physical strength.

[0003] Existing oxygen cylinders release gas by pressing, but due to the high pressure in the cylinder, long-term pressing causes sore fingers. At the same time, in an emergency, continuous oxygen supply is required to ensure the user's breathing, and the existing intermittent oxygen supply by pressing causes untimely oxygen supply, affecting the safety of the user. Therefore, a portable emergency breathing assist device is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a portable emergency breathing assistance device, including a gas cylinder, the upper end of the gas cylinder is connected to a pressing block, the surface of the pressing block is sleeved with a wrapping cover, the upper end of the gas cylinder is fixed with a connecting block, the surface of the connecting block is rotatably connected to a rotating frame, the upper end of the pressing block is provided with oblique teeth, the bottom of the rotating frame is rotatably connected to an inclined plate, and a spring is fixed between the rotating frame and the inclined plate.

[0006] Preferably, a connecting column is fixed on the surface of the connecting block, a rotating groove is provided on the surface of the rotating frame, and the connecting column is rotatably connected to the rotating groove.

[0007] Preferably, a guide groove is provided on the surface of the rotating frame and the guide groove is communicated with the rotating groove.

[0008] Preferably, the wrapping cover is made of elastic material, an air outlet pipe is fixed on the surface of the pressing block, and the air outlet pipe is connected to the wrapping cover.

[0009] Preferably, the guide groove is in an "eight" shape and the end with a smaller opening is connected to the rotation groove.

[0010] Preferably, the rotating frame is arc-shaped and the curvature of the rotating frame is consistent with the curvature of the inner edge of the gas cylinder.

[0011] Compared with the related art, the portable emergency breathing assist device provided by the utility model has the following beneficial effects:

[0012] The utility model changes the position of the oblique teeth by rotating the frame, and the spring fixes the angle of the oblique teeth, so that the oblique teeth can press the pressing block downward, thereby ensuring that oxygen can flow out continuously and avoiding oxygen waste caused by excessive pressing.
