Targeted oxygen supply device for dynamic sitting posture breathing area of person

Abstract

The invention discloses a targeted oxygen supply device for a dynamic sitting posture breathing area of a person. The device comprises a main body; the main body is of a hollow cavity structure; an oxygen inlet communicated with an inner cavity of the main body is formed in the main body; an oxygen outlet supporting plate is arranged on the face, opposite to the oxygen inlet, of the main body; the oxygen outlet supporting plate comprises a first mounting plate and a second mounting plate which are spliced with each other; the oxygen outlet supporting plate is outwards provided with at least four oxygen outlets communicated with an inner cavity of the oxygen outlet supporting plate; the oxygen outlets are distributed in a matrix mode; and a matrix is in bilateral symmetry with the splicing line of the first mounting plate and the second mounting plate as a symmetry axis. Through reasonable arrangement of a component structure, on the basis of capturing a human body breathing area in a sitting posture state and on the basis of determining an oxygen supply target area, full-coverage oxygen supply of the breathing area is realized, the accessibility of oxygen supply is improved, and a multi-oxygen-outlet coupling mode is adopted, so that the oxygen concentration distribution of the breathing area is more uniform, the oxygen consumption is saved by 65%, and meanwhile, a non-direct-contact oxygen supply mode can also reduce the influence of wearing the oxygen supply device on the physical and psychological reaction of the person.

Description

technical field [0001] The invention belongs to the field of oxygen supply, relates to an oxygen supply device, in particular to a targeted oxygen supply device for a dynamic sitting breathing area of ​​a person. Background technique [0002] In the room where the air conditioner is running, it is often necessary to keep the doors and windows closed to ensure the effect of the air conditioner; the respiration of the indoor personnel consumes oxygen and releases carbon dioxide; oxygen content drops. Being in a state of hypoxia for a long time will cause discomfort, drowsiness, unresponsiveness, and decreased work efficiency, which will affect people's physical and mental health, especially in offices and other places where people are dense and need enough oxygen to ensure work efficiency. Oxygen preparation mainly consumes electric energy. If the process of oxygen preparation to act on the human body is considered, it is a relatively difficult choice to consider the supply s...

AI Technical Summary

Problems solved by technology

Distributed oxygen supply needs to be used with specific devices, such as nasal cannula, breathing mask, etc. This method has a good oxygen supply effect and relatively low oxygen consumption, but it will restrict personnel activities and cause a foreign body sensation on the face during use; diffuse type Oxygen supply is to directly send high-concentration oxygen into the room through the terminal device to increase the oxygen content in the room. This oxygen supply method requires room airtightness and ventilation, and has high operating costs, large oxygen consumption, and poor oxygen supply effect. And other issues
