Description

Non-integrated full-isolation protective clothing

Technical Field

The invention relates to the technical field of sanitary protection equipment, in particular to virus protective clothing.

Background

At present, the new coronary pneumonia is more and more severe and has extremely high infectivity, and the current research shows that the transmission path of the new coronary pneumonia is mainly divided into the following two points. First, the transmission of human-to-human respiratory droplets, pathogens from virus carriers through the secretions and droplets discharged during coughing, sneezing, and speaking, into the mucosal surfaces of susceptible people, infecting them with the virus. Secondly, contact transmission, namely, after the healthy people contact the object with the secretion of the infected person, the virus is transmitted through touching the mouth, the nose or the eyes. Therefore, protection measures should be taken against the novel coronavirus to cut off the transmission path. However, since medical staff are treating patients and around them for a long time, they are more likely to be infected with viruses, and conventional disinfection and sterilization cannot effectively prevent viruses from invading human bodies. Medical personnel often use isolation protective clothing to protect. There are protective clothing of more forms among the prior art, for example CN202010155567.1 one kind can prevent medical personnel by the medical protective clothing of disjunctor of viral infection, it is specific disclose a reasonable in design, it is convenient and comfortable to dress, the hood of this protective clothing, protective trousers, gloves and shoe cover adopt disjunctor structure, can effectually prevent that the virus from soaking from the seam crossing of protective clothing, the effectual risk that medical personnel are infected that has reduced, the medical personnel's security performance has been improved and medical personnel can be prevented the medical protective clothing of disjunctor of viral infection. However, the protective clothing has the following defects that the head of the protective clothing still needs to be provided with the mask, only part of the head of the protective clothing is made of transparent materials, and if the head cover is provided with the protective clothing, the relative position between the head and the head cover is not fixed and is very uncomfortable, and the protective clothing is still inconvenient to observe the surrounding environment and is more inconvenient for surgical operation. CN201711351605.5 medical multifunctional protective clothing and a using method thereof disclose another kind of medical protective clothing, although the design of the protective clothing with better air permeability is completed, the sealing performance of the protective clothing cannot be ensured by adopting a zipper type matching mode, the wearing difficulty of the protective clothing is increased, and the zipper type matching disassembly and installation are difficult to combine together under the condition that the protective clothing and the protective clothing are completely separated. In addition, the protective clothing of most integral type design among the prior art adopts malleation protective clothing, it is convenient to wear, comfortable, the interior air flow of clothes is sultry not like CN03217138.2 a ventilation safety isolation clothes provides one kind, can conveniently wear isolation clothes and urinate, still can remove the trouble safety isolation clothes of wearing gauze mask and isolation glasses from, but adopt the connection design of integral type and use compressed air source and one-way exhaust, must have the life short, the problem that use cost is high, isolation clothes inevitable is in little inflation state all the time simultaneously, there is more inconvenience in the course of the work. In summary, the present invention aims to provide a non-integrated full-isolation protective garment, which is convenient to use, breathable, comfortable, cheap in manufacturing cost and recyclable.

Disclosure of Invention

The invention aims to provide a non-integrated full-isolation protective garment, which is convenient to wear and work after being worn, is comfortable for a user, and can not cause the problems of poor working state and further working accidents caused by the problems of dryness, heat, vexation and the like caused by air impermeability because of great visual interference caused by wearing the isolation garment. In order to solve the problems, the invention adopts the following technical scheme:

4. The air inlet and the air outlet of the protective clothing are filtered by the anti-virus filter element, and the air outlet filtering is also particularly important in the virus prevention and treatment process, because in the virus prevention and treatment process, doctors are always in a high-risk environment, are in long-time contact with patients and are in an environment with virus aggregation for a long time, and have higher infection risk, particularly aiming at the current manmade coronavirus which is abused frequently, the infection is easy, the virus latency period is long after the infection, and under the condition that symptoms are not obvious in the latency period, medical workers are infected with the virus without knowing, and the virus is easily carried to a safe environment or is spread to other patients or colleagues. By using the protective clothing, the situations can be avoided, and not only other people but also the user can be isolated.

5. The hood of protective clothing adopts new-type support, and the support also acts as second floor air filter simultaneously, and the softness is ventilated between new-type in the use to can fix hood and head, make the head be in suitable position in the hood, the sight is wide not limited, is in the hood and feels comfortable.

6. Shoes and gloves are independently connected, and the replacement can be carried out when the shoes and gloves are broken, and the replacement cost is low due to the adoption of a common design scheme.

7. The design of non-integral type is kept apart entirely makes its disinfection convenient, and the staff gets into the disinfection room after finishing work and wholly disinfect can, and the disinfection is convenient further to make the improvement of wearing the frequency of taking off, can take off when eating, going to the lavatory, has avoided because fear of extravagant protective clothing or fear behaviors such as fasting, urine suffocated that the troublesome disinfection of fear leads to.

8. The technical scheme of the invention has low manufacturing cost, good use freedom degree and comfort level and can be recycled for many times.
