Description

Double-layer composite positive pressure medical protective clothing

Technical Field

The utility model belongs to the technical field of protective clothing, and particularly relates to positive pressure three-stage medical protective clothing which can be used for health protection of general people in special environments such as epidemic areas, sand storm, haze and dust, or immune protection of susceptible people on daily commute.

Background

The three-level medical protection requires that the protective clothing worn by medical personnel can strictly prevent water, blood stain, splash and body fluid, effectively isolate bacteria, viruses, dust and the like in the environment of a ward area, particularly deal with various virulent viruses spread by air and aerosol, and more requires that the medical personnel wear the three-level medical protective clothing with high protection requirements, but the three-level medical protective clothing widely used at present is generally non-positive pressure disposable protective clothing and cannot stop occupational exposure. For the bacterium virus in isolated ward environment, medical personnel often need to wear the disposable isolation clothes of one deck, the disposable protective clothing of one deck, wear panorama protective face mask or goggles, the medical gauze mask of two-layer high face that hides that ties hard is worn to the mouth, two-layer latex gloves are worn to the hand, wear the high-order cover of latex glove on the cuff again, the trouser legs mouth then ties and embolias in boots or the shoe cover, this can reach the protection requirement certainly, but the long-time work protection of 6-8 hours even more than 10 hours that comes with it, lead to medical personnel to generally bear following misery and inconvenience:

1. the medical staff is sultry and easy to sweat due to the fact that heat cannot be effectively dissipated, and the body feeling is poor;

2. the bridle of the mask is tightly pressed on the cheek and the nose bridge for a long time with high strength, so that the mild skin of the face of the medical staff is subjected to blood stasis and edema, the impression is deep purple, the severe skin is allergic and inflamed, even the skin is broken to bleed, and the pain is difficult to endure;

3. protective masks and goggles are easy to gather water mist and even condense into water drops, which causes obvious visual impairment for medical care personnel;

4. when the shoes are worn for a long time, particularly in a high-temperature environment, the shoes are often experienced with chest tightness, oxygen deficiency and dyspnea.

In order to solve the problems, domestic individual manufacturers (such as camel TUORen) put forward positive pressure medical protective clothing to the market, but the positive pressure medical protective clothing is not widely popularized and used, and the reasons are mainly that:

1. the use cost is very high: the existing marketed positive pressure medical protective clothing is also disposable protective clothing, can not be repeatedly used for many times, the price of the marketed positive pressure medical protective clothing is often 15-20 times that of the common disposable medical protective clothing, and the comprehensive cost of disposable use is very high by calculating the flat use cost of each thousands of fan systems;

2. poor gas transmission dispersivity: local concentrated gas transmission is generally adopted in the internal near-body space of the protective clothing, the evacuation uniformity is poor, and obvious local somatosensory discomfort can be generated after the protective clothing is worn for a long time;

3. voice communication presents obstacles: the head of a medical worker wearing the protective clothing is positioned in the window hood sealed by positive pressure, the mask is arranged, and the continuous wind noise generated by the air transmission of the fan is added, so that obvious obstacles are caused to the voice communication of the doctor and the patient;

4. the auxiliary function is insufficient: including difficulty in identifying the identity of the wearer after wearing the protective clothing and inconvenience in carrying articles with the wearer.

Aiming at the defects or flaws of the existing disposable medical protective clothing and the disposable positive pressure medical protective clothing, the utility model provides the double-layer composite positive pressure medical protective clothing which can relieve the pain of medical staff caused by wearing the disposable protective clothing and a mask, can provide powerful support for voice communication, visual identification and carry-on articles, can be cleaned and disinfected by a medical cleaning and disinfecting machine after being used, can be repeatedly used, and has obvious safety, comfort, economy and environmental protection.
