Soft oxygen cabin with self-adjusting cabin body

Abstract

The invention provides a soft oxygen cabin with a self-adjusting cabin body. The soft oxygen cabin comprises the cabin body, a gas incoming assembly and a manual adjusting valve, the cabin body is surrounded to be isolated from the outside and forms an oxygen containing space, the gas incoming assembly communicates or isolates the outside and the oxygen containing space, an opening-closing device is arranged above inner zippers of the cabin body, the cabin body further comprises a soft interlayer, and two sides of the soft interlayer are fixed at the bottom of the inner side of the cabin body respectively. When the oxygen containing space is filled with gas, the soft interlayer is opened to be in a straight state, and when the oxygen containing space is not filled with gas, the soft interlayer is folded and stored; the inner zippers play a role in pressure bearing and sealing respectively, thereby effectively playing a special role respectively. A deflation valve and an emergency valve can automatically adjust over pressure and under pressure states respectively, and suffocation of personnel in the cabin can be prevented effectively in special accidents.

Description

technical field [0001] The invention belongs to the field of oxygen chambers, and relates to an oxygen chamber capable of self-regulating safety. Background technique [0002] The current use of oxygen chambers cannot be widely promoted and applied, mainly because the current oxygen chambers are large in size, complex in structure, expensive, and not safe, requiring personnel with professional knowledge to operate them. Patent No. 201110065138.6 discloses a portable soft air pressure oxygen chamber, which can effectively reduce the occupied volume. However, this scheme has some improvements: the opening and closing device at the opening position uses a double-layer structure of inner and outer zippers for airtightness and ventilation. Using the same structure to achieve two effects has its advantages, but the effect of ventilation and sealing is still not up to the mark. Ideally, the reason is that the connection structure of the two layers is closed by folding. The folding...

Problems solved by technology

However, this scheme has some improvements: the opening and closing device at the opening position uses a double-layer structure of inner and outer zippers for airtightness and ventilation. Using the same structure to achieve two effects has its advantages, but the effect of ventilation and sealing is still not up to the mark. To the ideal, the reason is that the connection structure of the two layers is closed by folding. The folding method can be more effective for sealing, but it cannot be completely sealed. Therefore, the airtight performance of this structure needs to be improved.

At the same time, a support frame is used outside the cabin to support it, and a mattress is set between the two to lay the human body, which leads to a problem that it cannot be stored as a whole in the length direction, and the volume it occupies is still relatively large

At the same time, in the case of low internal air pressure, the above-mentioned patent adopts the gradual introduction of oxygen between the double-layer surfaces to achieve relief. For a long time, or a large pressure difference is required to form a rapid ventilation, which is a safety hazard for the human body
