Description

Protective clothing

Technical Field

The invention relates to the technical field of protective articles, in particular to protective clothing.

Background

The protective clothing is a main barrier for isolating harmful substances such as germs, dust, liquid and the like and protecting the safety of a wearer. However, existing protective garments, particularly medical protective garments, suffer from various disadvantages, such as:

1) not totally enclosed, when the staff dressed, facial exposure was outside, need cooperate gauze mask and goggles to use together, but gauze mask and goggles can not wrap up the face that exposes completely, caused the protection short slab, easily caused the invasion of virus, bacterium, dust etc. and increased the infection risk, increased the personnel's of dressing psychological pressure. In addition, the two sides of the nose wing of the mask can not be completely attached to the nose wing, and the left gap can lead part of air to be inhaled into a human body without being filtered in the breathing process, so that the protection function is reduced.

2) The protective clothing cap, the mask and the goggles are overlapped, and the wearing process is complex and clumsy. If the mask and the goggles are not worn tightly enough, the air tightness is not good; the protective mask is difficult to wear, the problems of headache, dizziness and the like easily occur, the problems of high local temperature, poor air permeability, unsmooth blood flow and the like can be caused after the protective mask is worn for a long time, serious tightening marks (particularly the impression of goggles), allergy, facial skin injury and the like can be caused, once the facial skin is injured, the protective barrier of the protective mask can be lost, and the risk of exposure infection is increased. Moreover, the wearing process of the existing protective clothing is complicated, time and labor are wasted, and the relative positions of the hat, the mask and the goggles can be changed in the using process, particularly when the protective clothing works in a polluted area, and if the protective clothing is not processed correctly in time, the safety risk can be increased.

3) Existing non-fully enclosed protective clothing tends to expose the operator's hair, which also increases the risk of infection, and is why many medical personnel have to cut short hair or even "shave" hair. This can also cause significant psychological stress on healthcare workers, particularly female healthcare workers.

4) The goggles are easy to generate water mist, and the sight of an operator is influenced, so that diagnosis and treatment operations are influenced.

5) The goggles are costly to use, resulting in waste and large amounts of medical waste.

6) The traditional protective clothing is the normal pressure protective clothing, the internal and external pressure of the protective clothing is the same, and bacteria, viruses, dust and the like are difficult to completely prevent from entering the interior of the protective clothing, so that the protective effect is influenced.

7) The traditional non-totally enclosed protective clothing is difficult to comprehensively and carefully check whether air leakage exists at the sealing and connecting positions, whether quality defects exist in materials and the like. And in the wearing and use process of the wearing person, if the conditions such as damage and leak occur, the condition can not be found in time, the infection risk of the wearing person is increased, and the psychological pressure can be caused.
