FIG. 2 is a schematic view of the appearance of the protective garment;

FIG. 3 is a schematic view of a nasal mask;

in the figure: the nose mask comprises a window 1, a first vent hole 2, a second vent hole 3, a third vent hole 4, a fourth vent hole 5, a pocket 6, an air suction pipe 7, an air expiration pipe 8, a bandage 9, a nose mask 10, a filter screen 11, an inner bayonet 12, an inner inserting interface 13, an outer bayonet 14 and an outer inserting interface 15.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

One sealing arrangement for the vent of fig. 1:

when the outer bayonet 14 is arranged to be plugged into the inner bayonet 12, the hole diameter is tightly matched, and the filter screen 11 is arranged in the outer bayonet 14.

The aperture of the inner bayonet 12 is smaller than the aperture of the non-woven fabric reserved in the first ventilating hole 2 of the protective clothing.

The inner bayonet 12 props against the non-woven fabric of the first vent hole 2 from the inside, and the outer bayonet 14 presses the non-woven fabric of the vent hole to be plugged into the inner bayonet 12 for close connection.

The plug-in connection 13 is used for connecting the suction pipe 7.

Except the above inner and outer bayonet pressing sealing modes, the vent hole and the plug port can also be fixed by other modes such as a built-in filter screen and non-woven fabric integrated hot melting sealing fit, the filter screen can also be detachably mounted, and the plug port and the air suction pipe can also be directly inserted, screwed by screw threads and plugged by a fire hydrant.

Example 1

Stay for a short time in a work environment needing protection:

the protective clothing is the disjunctor clothing with hood, and the head support is worn overhead, wears the protective trousers of disjunctor clothing in proper order, and the protective clothing covers the head support, and the tight front driving fit zip fastener of protective clothing is strained to the hood, dresses the completion. The air in the cavity between the protective clothing and the body is exchanged with the outside through the vent holes.

This embodiment is suitable for use in a work environment requiring protection for a short period of time without the use of a nasal mask or air delivery device.

Example 2

The head support is worn on the head, the bandage 9 bypasses the head support to tightly bind the nose mask 10 on the head cover, protective trousers and protective clothes are worn, the air suction pipe 7 is inserted into the inner insertion interface 13 of the first vent hole 2, and the air expiration pipe 8 is inserted into the inner insertion socket of the second vent hole 3. The head support is covered on the head hood, the chest sealing zipper of the protective suit is tightened, the blower is put into the pocket 6, and the blower is connected with the external inserting interface 15 of the first vent hole 2 and the external inserting interface of the third vent hole 4 through the blast pipe. And finishing wearing.

When in inspiration, the air sent by the blower is filtered by the filter screen 11 of the first vent hole 2 to reach the nasal cavity, and when in expiration, the air is discharged through the second vent hole 3; the air of the blower enters the cavity between the protective clothing and the body through the filter screen of the third vent hole 4, and the air discharges sweat through the far-end fourth vent hole 5.

The nasal mask 10 separates the breathing air passage from the air within the hood window 1, preventing condensation of water vapor on the window.

When the protective clothing is taken off, the blast pipes externally connected with the first vent hole 2 and the third vent hole 4 are sequentially pulled out; opening the chest zipper; an air suction pipe 7 connected with the first vent hole 2 in an inscribed mode and an air expiration pipe 8 connected with the second vent hole 3 in an inscribed mode are pulled out; taking off the head cover and protecting the clothes and trousers; the straps 9 are unfastened, the nose mask 10 is removed, the head support is removed and the vent screen 11 is replaced as necessary.

The first vent hole 2, the second vent hole 3, the third vent hole 4 and the fourth vent hole 5 are respectively marked with a plurality of vent holes for the convenience of explanation, and the marks shown in figure 2 are not fixed positions and can also be arranged at other places of a hood, a jacket and trousers.

Example 3

This example followed the dressing procedure of example 2.

The isolation area that need wear protective clothing work is generally limited to fixed places such as laboratory or hospital ward, can utilize indoor air-cooler, connects the air supply pipe of No. three air vents 4 with the air-cooler at the working gap, and cold wind gets into the cavity between protective clothing and the health through No. three air vents 4 filter screens, and the sweat is discharged from No. four air vents 5 of distal end, pulls out the blast pipe after the health resumes and continues work.

It should be noted that in examples 2 and 3, air is introduced from the third vent hole 4, and the exhaust from the fourth vent hole 5 should not be limited to the fixed position shown in fig. 2, and any ventilation scheme for circulating air between the protective suit and the body cavity is within the scope of the present technology.

The air supply devices shown in the above examples 2 and 3 can be multifunctional machines with sterilization, oxygenation and the like besides the single-function portable hair dryer and the air cooler, the common hair dryer is mature and low in cost, the air cooler only needs to be simply transformed and provided with the air supply pipes, the implementation is easy, the problems that medical staff and health staff sweat, and the diaper is uncomfortable to wear can be solved, and the effect is obvious. The portable auxiliary air supply device can be placed on the waist of the user together with the pocket 6 or the waist bag, and the user can carry the portable auxiliary air supply device on the north, and the portable auxiliary air supply device is not limited to the position of the pocket 6 shown in the figure.

Example 4

For the protective clothing needing to wear the mask and the goggles separately, a head support and a nose mask are not needed, the protective clothing is only provided with a plurality of vent holes, an air supply pipe of the air supply device is connected with an external insertion interface of the third vent hole 4, air enters a cavity between the protective clothing and the body through a vent hole filter screen, and the air discharges sweat through the fourth vent hole 5 at the far end.
