Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of suffocation first aid devices, in particular to a simple respirator. Background Art
[0002] The shortcomings of current emergency measures for choking, such as the traditional Heimlich maneuver, are as follows: 1. It requires training and learning to master. 2. Excessive force may cause organ damage, rib fractures, internal organ damage, etc. 3. If the force is not enough, the foreign body cannot be expelled, which may endanger life. 4. In case of choking and breathing difficulties, it is necessary to call for help in time, otherwise it may cause excessive panic and tension.
[0003] The principle of similar anti-suffocation products is to generate negative pressure through a specific device, and then connect the respiratory tract with the negative pressure cavity to achieve the purpose of clearing the obstruction. The structures used for pumping negative pressure are mainly piston-type and hand-pull accordion-type. Among them, the piston type has a long stroke and a slightly slow effect; the hand-pull accordion type has a short stroke and a fast effect, but most of them are roughly made, poorly sealed, and the grip part is too small, which does not conform to the principles of ergonomics.

A mounting groove is provided at the center of the lower side of the handle pull ring, and a vent hole is provided at the uppermost end of the mounting groove. A small one-way valve is clamped in the middle of the mounting groove. An annular clamping groove is provided at the lower end of the mounting groove. An annular clamping joint provided at the upper end of the organ body is clamped in the annular clamping groove. The organ body is a circular organ-shaped airbag, and vent holes are provided at the upper and lower ends. The vent hole at the upper end is located in the annular clamping joint, and the small one-way valve is connected with the inner cavity of the organ body and the vent hole on the handle pull ring; a large The one-way valve mounting hole has a circular sealing ring mounting groove on the lower side. The large one-way valve is inserted into the central mounting hole of the upper base from the lower side. After the circular sealing ring is installed in the mounting groove on the lower side of the upper base, the upper base is placed into the inner cavity at the lower end of the organ body.
