Description

Isolation protective clothing

Technical Field

The utility model relates to a medical protective equipment technical field, very much relate to an isolation protective clothing.

Background

During epidemic of infectious diseases, medical care personnel and people in close contact with patients with infectious diseases need to wear protective clothing, and in order to ensure the protection effect, the protective clothing generally has good sealing performance, so that blood, body fluid, air dust and bacteria can be effectively resisted. On the other hand, the mouth mask needs to be worn for protecting the mouth and the nose, so that the transmission of viruses can be blocked, and the smooth breathing can be ensured.

Due to the sealing property of the protective clothing, the body of the medical care personnel can not be ventilated with the outside under the wrapping of the protective clothing, and the sweat can be easily drenched. During the epidemic period of the infectious diseases, medical staff usually need long-time high-load work, and the physical strength of the medical staff is more easily consumed by a large amount of sweating. Therefore, how to make the protective clothing have the ventilation function on the basis of ensuring the protection effect becomes a problem to be solved urgently.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a structural design is reasonable, can improve the isolation protective clothing of gas permeability on the basis of guaranteeing the safeguard effect.

In order to solve the technical problem, the utility model discloses a following technical scheme:

an isolation protective garment comprises a protective garment body, and is characterized in that the protective garment body is provided with at least one breathable protective part, and the breathable protective part is positioned on the body at a position corresponding to a joint part of a body; the breathable protection part comprises an outer water-resistant layer, a filtering layer and an inner moisture-absorbing layer which are all breathable, and the outer water-resistant layer, the filtering layer and the inner moisture-absorbing layer are sequentially stacked from outside to inside; the filter layer is made of at least one layer of melt-blown non-woven fabric.

Because the protective clothing has good closure under the wearing state, and the position corresponding with the health joint on the protective clothing body can receive the extrusion or pull the deformation when the human body is walked or is moved for air in the protective clothing can outwards be discharged through ventilative guard portion when the extrusion, and when pulling, makes in the outside air can permeate the protective clothing from ventilative guard portion, realizes the breathing freely of protective clothing. And because the filter layer of the air-permeable protection part is made of at least one layer of melt-blown non-woven fabric, in the process that the outside air permeates into the protective clothing, the droplets in the air are adsorbed on the surface of the non-woven fabric by static electricity after being close to the melt-blown non-woven fabric and cannot permeate through the non-woven fabric, and the air-permeable protection part is ensured to have a good protection effect.

Furthermore, the breathable protection parts are provided with a plurality of breathable protection parts which are respectively positioned at the positions corresponding to armpits, groins and/or leg pits on the body.

The protective clothing is provided with a plurality of breathable protective parts, so that the whole protective clothing has a better breathable effect. Furthermore, armpits, groins and leg pits usually have abundant sweat glands, and the breathable protective parts are arranged at the positions, so that sweat can be better improved.

Further, the outer water-resistant layer is made of needle-punched cotton; the inner moisture absorption layer is made of spun-bonded non-woven fabric.

The acupuncture cotton is mainly used for manufacturing the N95 protective mask, is thicker than spun-bonded non-woven fabric, has better strength and is not easy to damage when being extruded or pulled; and the support nature of acupuncture cotton is good, when dragging, more enables the protective clothing inner space increase, makes inside formation local negative pressure, the infiltration of the outside air of being convenient for.

Furthermore, a plurality of breathable protection parts are arranged, wherein a barrier layer is arranged on the inner side of the inner moisture absorption layer of at least one breathable protection part in a laminated mode, and a ventilation port is formed in the barrier layer inwards; the active air exchange device comprises a shell, an air exchange fan, a power supply and a control module for controlling the air exchange fan to rotate are arranged in the shell, and the air exchange fan and the power supply are both connected to the control module; the shell is provided with an air suction port and an air expiration port which are respectively communicated with the air inlet side and the air outlet side of the ventilation fan, and the air suction port is connected with the ventilation port of the blocking layer through a detachable air pipe.

Like this, control ventilation fan through control module and rotate for ventilation fan's air inlet side produces the negative pressure, and then makes also to form the negative pressure between barrier layer and the interior wet layer of inhaling through the trachea connection, and the outside air of being convenient for enters into the protective clothing from ventilative guard portion, realizes fresh air's replenishment, and the air in the protective clothing is outwards discharged through other ventilative guard portions. When the protective clothing is used specifically, the ventilation speed can be adjusted by controlling the rotation speed of the ventilation fan, so that micro-positive pressure is formed in the protective clothing.

Further, the inner moisture absorption layers of the two air-permeable protection parts are internally provided with barrier layers which are arranged in a stacked mode; the shell is internally provided with two ventilation fans in a separated way, and the shell is provided with two groups of air suction ports and air exhaust ports which are respectively arranged corresponding to the ventilation fans; the air suction port corresponding to one of the ventilation fans is connected with the air exchange port of one of the barrier layers through a detachable air pipe, and the air expiration port corresponding to the other ventilation fan is connected with the air exchange port of the other barrier layer through a detachable air pipe.

During operation, fresh air can be inhaled from the external world through a ventilative guard portion in the induction port of a ventilation fan, and the exhaling mouth of another ventilation fan can be through the outside air of discharging in the protective clothing of another ventilative guard portion, just can realize the circulation of the inside and outside air of protective clothing, makes the protective clothing can breathe freely with the external world, improves and dresses the travelling comfort.

Furthermore, the inhalation port corresponding to one of the ventilation fans and the exhalation port corresponding to the other ventilation fan are located at positions far away from each other on the housing.

Thus, the fresh air fed by one air inlet can be prevented from being directly sucked by the other air inlet and discharged.

Furthermore, a binding belt for fixing the shell on the body is further arranged on the shell of the active ventilation device.

Further, the bandage is a waistband.

To sum up, the utility model has the advantages of structural design is reasonable, can improve the gas permeability on the basis of guaranteeing the protecting effect, improves and dresses the travelling comfort.
