Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, a medical isolation protective hood for improving comfort and safety comprises an outer hood body 1, a breathing mask body 2, a forehead fixing band 3, an ear side fixing band 4 and a neck fixing band 5; the breathing mask body 2 is hermetically arranged at the front part of the outer mask body 1 in a penetrating way, one end of the breathing mask body 2 is positioned at the outer side of the outer mask body 1, and the other end of the breathing mask body 2 is positioned at the inner side of the outer mask body 1; the forehead fixing band 3 is positioned at the top end inside the outer cover body 1, the ear side fixing band 4 is positioned inside the outer cover body 1 and connected to the breathing mask body 2, and the neck fixing band 5 is positioned at the bottom of the outer cover body 1; the side part or the rear part of the outer cover body 1 is provided with a filtering air window 6, and a filtering material interlayer is embedded in the filtering air window 6.
As for the position of the filter louver 6, it is basically possible to do without affecting the position of the line of sight and the breathing, and in practical design, the filter area of the filter louver 6 is as large as possible, so that the air flow velocity through the filter louver 6 can be faster, and the lower the pressure difference across the filter louver 6, the higher the comfort during breathing.
The forehead fixing band 3 can be adjusted according to the size of the head circumference of the wearer, so that the outer cover body 1 is fixed with the head of the wearer; the ear side fixing belt 4 can also be adjusted according to the size of the head circumference of the wearer, and is used for fixing the breathing mask body 2 on the face of the wearer and accurately covering the mouth and nose of the wearer, and the ear side fixing belt 4 can adopt an annular fixing belt structure or a triangular fixing belt structure; the neck fixing band 5 is used for fixing the lower part of the outer cover body 1 on the neck of a wearer, and the tightness of the neck fixing band 5 can be adjusted in a magic tape mode.
The inner mask opening of the breathing mask body 2 is used for buckling the mouth and nose part of a wearer, the surface of the inner mask opening of the breathing mask body 2 is provided with a cotton coating layer, and a silica gel ring is arranged between the cotton coating layer and the inner mask opening of the breathing mask body 2; a buckle cover 7 is arranged at the outer end cover opening of the breathing mask body 2, and a filtering material interlayer is embedded in the inner layer of the buckle cover 7; a partition plate 8 is arranged at the middle front part of the breathing mask body 2, and a one-way exhaust valve 9 is arranged on the partition plate 8; the breathing mask body 2 at the rear side part of the clapboard 8 is provided with a one-way inhalation valve 10, a filtering material interlayer is embedded in the one-way inhalation valve 10, and the air inlet port of the one-way inhalation valve 10 is communicated with the outside of the mask body 1 through a filtering air window 6.
When a wearer exhales, only the one-way exhaust valve 9 is opened, the one-way inhalation valve 10 is in a closed state, and exhausted air exhaled by the wearer firstly enters the outer side of the partition plate 8 through the opened one-way inhalation valve 10 and then is exhausted out of the mask after passing through the filtering material interlayer embedded in the inner layer of the buckle cover 7. In the actual design, the volume of the exhaust area between the inner side of the partition plate 8 and the mouth and nose should be reduced as much as possible so as to reduce the storage amount and the retention time of the exhaust in the area and avoid the phenomenon of oxygen deficiency and dizziness caused by long-time wearing of a wearer. When a wearer inhales, only the one-way air suction valve 10 is opened, the one-way exhaust valve 9 is in a closed state, and air outside the hood enters the breathing mask body 2 through the filtering material interlayer embedded in the one-way air suction valve 10, so that the air suction smoothness is ensured, and the air suction safety is also ensured.
The temperature and humidity adjusting cover is characterized in that a temperature and humidity adjusting belt zone 11 is arranged at the top of the outer cover body 1, an insert piece type drying agent and an ice bag are arranged in the temperature and humidity adjusting belt zone 11, the humidity inside the outer cover body 1 is adjusted through the insert piece type drying agent, and the temperature inside the outer cover body 1 is adjusted through the ice bag. After the wearer finishes wearing the medical isolation protective hood, the inserted sheet type drying agent and the ice bag in the temperature and humidity adjusting belt zone 11 can be taken out, the inserted sheet type drying agent can be replaced with new one, the old inserted sheet type drying agent can be reused after dehydration, and the ice bag is directly put into the freezer and is continuously used for the next time.
And an adhesive connection mode, an opening gland connection mode or an inserting plate connection mode is adopted between the filtering transom 6 and the outer cover body 1.
The selection of the filtering material interlayer can be selected according to the standards set by the health management department, or can be selected higher than the standards, if the filtering material interlayer is used in an operating room, the standards can be higher than the standards, if the filtering material interlayer is used in a non-operating room, the standards can be lower than the standards, but the air permeability standard cannot be reduced.
The embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications without departing from the scope of the present invention are intended to be included in the scope of the present invention.
