Abstract

The utility model relates to an integral type oxygen face guard, including the face guard body, the front side lower extreme of face guard body be provided with the mixed cavity of admitting air, the lower extreme of the mixed cavity of admitting air be connected with the intake pipe, the lateral wall of the mixed cavity of admitting air on open and to have mixed inlet port, the mixed cavity of admitting air, face guard body and intake pipe be the integrated into one piece structure. The utility model adopts an integral structure without other parts, and directly connecting the oxygen tube, thereby solving the problems of more parts of the original oxygen mask and inconvenient and easy loss in installation.

Description

Integral type oxygen mask
Technical Field
The utility model relates to an oxygen mask field especially relates to an integral type oxygen mask.
Background
The oxygen mask is a common medical article, and is required to be connected with an oxygen tube when in use, but pure oxygen is supplied for breathing of a patient to cause oxygen poisoning, and the oxygen and air are required to be mixed in the oxygen mask, so a mixing space is required to be arranged at an air inlet of the oxygen mask.
Disclosure of Invention
The utility model aims to solve the technical problem that an integral type oxygen mask is provided, adopt the structure of integral type, do not have other spare part, the lug connection oxygen hose can, solved original oxygen mask spare part many, the inconvenient problem of losing easily of installation.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an integral type oxygen face guard, includes the face guard body, the front side lower extreme of face guard body be provided with the air intake mixing cavity, the lower extreme of air intake mixing cavity be connected with the intake pipe, the lateral wall of air intake mixing cavity on open and to have mixed inlet port, air intake mixing cavity, face guard body and intake pipe be the integrated into one piece structure.
Furthermore, the diameter of the mixed air inlet hole is 4-8 mm.
Furthermore, the lower part of the air inlet mixing cavity is hemispherical, and the mixing air inlet is arranged on the side wall of the lower part of the air inlet mixing cavity.
Has the advantages that: the utility model relates to an integral type oxygen mask, simple structure adopts the structure of integral type, does not have other spare part, the lug connection oxygen hose can, it is many to have solved original oxygen mask spare part, installs the inconvenient problem of losing easily, and oxygen and air mixing are also more swift moreover.
Drawings
FIG. 1 is a perspective view of the present invention;
fig. 2 is a side view half-section structure diagram of the utility model.
The figure is as follows: 1. the mask comprises a mask body, 2, an air inlet mixing cavity, 3, a mixing air inlet, 4 and an air inlet pipe.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-2, the utility model discloses an embodiment relates to an integral type oxygen face guard, including face guard body 1, face guard body 1's front side lower extreme be provided with air intake mixing cavity 2, air intake mixing cavity 2's lower extreme be connected with intake pipe 4, air intake mixing cavity 2's lateral wall on open and to have mixed inlet port 3, air intake mixing cavity 2, face guard body 1 and intake pipe 4 be the integrated into one piece structure.
The diameter of the mixed air inlet hole 3 is 4-8mm, and the size of the mixed air inlet hole 3 can be set according to oxygen masks with different sizes.
The lower part of the air inlet mixing cavity 2 is hemispherical, the mixing air inlet 3 is arranged on the side wall of the lower part of the air inlet mixing cavity 2, so that the mixing air inlet 3 is in an oblique state, when oxygen enters the air inlet mixing cavity 2, external air can be sucked into the air inlet mixing cavity 2 from the mixing air inlet 3 due to the Venturi principle, and the concentration of the mixed oxygen is about 55% -60%.
The utility model discloses simple structure adopts the structure of integral type, does not have other spare part, and the lug connection oxygen hose can, has solved original oxygen mask spare part many, installs the inconvenient easy problem of losing, and oxygen and air mixing are also more swift moreover.
