Abstract
The utility model relates to a medical protective article, in particular to a disposable respiratory tract isolation oxygen supply protective hood which is used for protecting and isolating medical care personnel and respiratory tract infectious disease patients. The breathing mask comprises a transparent mask body, wherein the mask body is of a double-layer structure, an outer layer is a supporting layer, an inner layer is a breathing layer, the bottoms of the inner layer and the outer layer are combined, and the upper interlayer space is inflated; the bottom of the hood is provided with an annular inflatable support ring, and a chest and back fixing belt is arranged below the annular inflatable support ring; the outer wall of the head cover is provided with a one-way/two-way breather valve and is communicated to the inside of the breathing layer. The novel medical hood is comfortable to wear, good in breathability and clearer in visual field during work, and the novel medical hood not only can be used as a protection of medical workers, but also can be used for isolating and protecting infectious disease patients.
Description
Technical Field
The utility model relates to a medical protective article, in particular to a disposable respiratory tract isolation oxygen supply protective hood which is used for protecting medical care personnel and respiratory tract infectious disease patients and supporting isolation and oxygen supply.
Background
The existing protective articles have defects and deficiencies, such as N95 mask is poor in breathability and incapable of realizing oxygen therapy after being worn for a long time, and if pressure wounds exist, the protective eye cover is prone to fogging in the cover, pressure sores are prone to being caused after being worn for a long time, and the protective eye cover is inconvenient to wear when being worn with glasses.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a disposable respiratory tract isolation oxygen supply protection hood.
The purpose of the utility model is realized through the following ways: a disposable respiratory tract isolation oxygen supply protective hood comprises a transparent hood body, wherein the hood body is of a double-layer structure, the outer layer is a supporting layer, the inner layer is a breathing layer, the bottoms of the inner layer and the outer layer are combined and inflated in an upper interlayer space; the bottom of the hood is provided with an annular inflatable support ring, and a chest and back fixing belt is arranged below the annular inflatable support ring; the outer wall of the head cover is provided with a one-way/two-way breather valve and is communicated to the inside of the breathing layer.
As a further optimization of the scheme, the supporting layer and the breathing layer are made of polyethylene transparent materials.
As a further optimization of the scheme, the air inflation valve arranged on the outer wall of the supporting layer is used for inflating between the supporting layer and the breathing layer.
As a further optimization of the scheme, the air pressure value between the supporting layer and the breathing layer is 20-30cmH2O。
As a further optimization of the scheme, the inflation valve has the functions of a pressure reducing valve and a pressure gauge.
As a further optimization of the scheme, the chest and back fixing belt is formed by connecting shoulder straps and chest straps.
As a further optimization of the scheme, the sealing ring is characterized in that an annular sealing skirt edge is fixed at the bottom of the annular inflatable supporting ring, and an elastic rubber band is arranged on the inner ring of the sealing skirt edge.
The utility model discloses disposable respiratory tract isolation oxygen suppliment protection hood, it is comfortable, the gas permeability is better to wear, and the during operation field of vision is more clear, and this kind of hood not only can regard as medical personnel's protection to use, can use infectious disease patient to keep apart protection and oxygen therapy to use moreover.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings:
FIG. 1 is a schematic structural view of the present invention;
in the figure, a supporting layer 1, a breathing layer 2, an inflation valve 3, an annular inflation supporting ring 4, a shoulder strap 5, a chest strap 6, a one-way/two-way breathing valve 7, a sealing skirt 8 and an elastic rubber band 9.
Detailed Description
As shown in fig. 1, the utility model discloses disposable respiratory tract is kept apart oxygen suppliment and is protected hood, it includes transparent hood, the hood is bilayer structure, the skin is supporting layer 1, the inlayer is for breathing layer 2, supporting layer 1 and breathing layer 2 are made for polyethylene transparent material, the inlayer bottom combines and aerifys in upper portion intermediate layer space, supporting layer 1 and breathing layer 2 between aerify through the inflation valve 3 of the installation of supporting layer 1 outer wall, inflation valve 3 have relief pressure valve and manometer function, face guard skin side device inflation valve and relief pressure valve and configuration manometer effective control skin pressure play the plasticity and stereotype effect. The air pressure value between the supporting layer 1 and the breathing layer 2 is 20-30cmH2And O. The outer wall of the head cover is provided with a one-way/two-way breather valve 7 and is communicated to the inside of the breathing layer 2. The two-way breather valve is used during normal protection, the one-way breather valve is used when respiratory infectious disease patients need oxygen supply, and the breather valve is directly externally connected with an oxygen input pipe and supplies oxygen through an oxygen supply channel.
The bottom of the hood is provided with an annular inflatable support ring 4 and a sealing ring, and the structure of the hood is that manual inflation is adopted in an inflatable air bag made of plastic materials, a sealing structure is formed at the neck of the hood, and the supporting function is achieved; the sealing ring is characterized in that an annular sealing skirt edge 8 is fixed at the bottom of the annular inflatable supporting ring 4, an elastic rubber band 9 is arranged on the inner ring of the sealing skirt edge 8 made of a plastic film, and the neck is sealed by the sealing ring after the head of a user is sleeved into the head cover. The chest and back fixing belt is arranged below the head cover to prevent the head cover from being separated in the using process. The chest and back fixing belt is formed by connecting a shoulder belt 5 and a chest belt 6.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions thought by the inventive work within the technical scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
