Embodiment 1

[0051] Compared with the traditional oxygen supply method, the oxygen-enriched environment in the entire room is realized through oxygen supply. In fact, in a specific working and living environment such as sleep, the oxygen supply only needs to supply oxygen to the mouth and nose area when the person is lying flat or turning over. This embodiment proposes an oxygen supply device for a breathing area in a dynamic sleeping position. The device includes a main body 1 spliced ​​by a first mounting plate 1-1 and a second mounting plate 1-2. The convex surface of the main body 1 is provided with 12 oxygen outlets 2. , each oxygen outlet 2 is arranged in a matrix, and the matrix is ​​symmetrical about the axis 3 with the splicing line of the first mounting plate 1-1 and the second mounting plate 1-2, and the first mounting plate 1-1 and the second mounting plate 1-1 and the second mounting plate 1-1 The angle α between the plates (1-2) is 160°, the structure of the oxygen outlet 2 a...

Embodiment 2

[0057] This embodiment is to verify the effect of Embodiment 1, specifically to carry out a full-scale test on the oxygen supply device of the present invention.

[0058] Carry out a full-scale experiment on the oxygen supply device. The experimental system is divided into an air supply part and an oxygen supply part. The air supply part is composed of a centrifugal fan, a soft connection, and a governor. , gas flow meter and connecting pipe. In order to ensure a uniform flow of oxygen-enriched oxygen at the oxygen outlet, the oxygen-enriched air is uniformly mixed in the static pressure box before being sent into the oxygen outlet, and the oxygen-enriched flow is passed into the 3D printing oxygen outlet through a rubber hose. The air volume of the fan is controlled by the governor, the oxygen flow rate is read through the gas flow meter, and the opening of the valve is changed to control it.

[0059] On the section of the breathing zone at 0.65m from the ground, select 20 r...

Embodiment 3

[0070] This embodiment is to verify the effect of Embodiment 1. Specifically, the schlieren imaging system is used to test the influence of human respiratory airflow and thermal plume on the targeted oxygen supply in dynamic sleeping positions. The experimental system consists of a camera, a light source, a real person and a concave surface. The lens composition, the diameter of the concave lens is 406mm, such as Figure 5 As shown, in the states of exhalation, breath holding and inhalation, the oxygen-enriched flow can still cover the breathing area of ​​the human body in the sleeping position, and the respiratory airflow and thermal plume have little effect on the oxygen supply effect of the targeted oxygen supply system. .

Abstract

Disclosed is an oxygen supply device for a breathing area of a dynamic sleeping posture of a person. The oxygen supply device comprises a main body, and the main body comprises a first mounting plate and a second mounting plate which are spliced with each other; and at least four oxygen outlets are formed in the convex surface of the main body and are arranged in a matrix, and the matrix is bilaterally symmetrical by taking a 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 the human body breathing area in a sleep state and on the basis of determining an oxygen supply target area, full-coverage oxygen supply of the breathing area is realized, and the accessibility of oxygen supply is improved; a multi-oxygen-outlet coupling mode is adopted, so that the oxygen concentration distribution of the breathing area is more uniform, and the oxygen consumption is saved by 42%; and meanwhile, the 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 personnel.

Description

technical field [0001] The invention belongs to the field of oxygen supply, relates to an oxygen supply device, in particular to an oxygen supply device for the breathing area of ​​a person in a dynamic sleeping position. Background technique [0002] Creating a good sleeping environment has a very important impact on improving the work efficiency of personnel and improving the health of personnel. Existing studies have shown that creating a comfortable oxygen environment has a very positive effect on improving people's sleep, especially for hypoxic places caused by factors such as closed indoor places and elevated altitudes. Then, how to create a comfortable indoor oxygen-enriched environment has become an urgent problem to be solved. [0003] In the traditional research on oxygen supply, the oxygen-enriched environment in the whole room is realized through oxygen supply. In fact, in a specific working and living environment such as sleep, the oxygen supply only needs to ...
