FIG. 1 is a side view of a medical positive pressure respirator hood according to an embodiment of the present invention;
FIG. 2 is a block diagram of a medical positive pressure respirator hood according to an embodiment of the present invention.
Detailed Description
The medical positive pressure respirator hood of the present invention can be made of, but is not limited to, the following materials, for example: organic glass, plastic, aluminum alloy, stainless steel, tetrafluoroethylene, polycarbonate, rubber, steel wire corrugated pipe, filter fiber, spray fiber, silica gel sheet, spring, fan and the like.
FIG. 1 is a side view of a medical positive pressure respirator hood according to an embodiment of the present invention; and is shown with reference to figure 2.
The medical positive pressure respirator hood of the embodiment of the invention comprises: a spherical transparent cover body 1, an air inlet pipe 2 and an exhaust baffle plate 4; the exhaust baffle plate 4 is positioned right above the top of the head of the human body, so that excessive heat can be conveniently exhausted, and hot air is prevented from being accumulated in the transparent cover body.
The bottom of the transparent cover body 1 is provided with a wearing opening, and the edge of the wearing opening is provided with a sealing skirt board 6; the sealing panels are typically used to adhere to the inside of the protective garment.
Usually, a fixing strap is arranged outside the sealing skirt board 6 to facilitate fixing on the human body.
The exhaust baffle 4 is arranged at the top of the transparent cover body 1, and a filter screen is arranged in the exhaust baffle 4; the filter screen is mainly used for exhausting the air in the transparent cover body 1; and a small amount of air entering the transparent cover body 1 enters after passing through the filter screen.
A dispersion pipe 10 is arranged in the transparent cover body 1, and a plurality of air inlet nozzles 11 facing to the mouth and the nose of a human body are arranged on the dispersion pipe 10; in general, the dispersion pipe 10 is disposed at the bottom of the transparent cover 1 in a circular arc shape.
Generally, the orientation of each air inlet nozzle 11 is adjustable so as to conveniently face the corresponding transparent cover body of the neck, mouth and nose, forehead or face of the human body.
One end of the air inlet pipe 2 is inserted into the transparent cover body 1, and the other end of the air inlet pipe is provided with an air inlet fan 3; the air inlet pipe 2 is inserted into the transparent cover body 1 and connected with the dispersion pipe 10.
In the use process, because the effect of inlet fan 3, a large amount of fresh air is introduced in the translucent cover body 1 through intake pipe 2, has higher pressure in the translucent cover body 1 relative to the outside air, and excessive waste gas and heat are discharged through exhaust baffle 4 under the positive pressure effect simultaneously.
