Description

Medical isolation protection sterile cap

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medical isolation protection sterile cap.

Background

In the process of resisting the novel coronavirus infection pneumonia, in order to resist the invasion and infection of viruses, medical care personnel must wear medical protective masks and goggles or protective masks, and the like. Studies have shown that hospital-acquired stress injuries have a 5.4% incidence, with 34.5% being device-related stress injuries, and the risk of stress injuries for those using medical devices is 2.4 times that of non-users. It is seen that the incidence of stress injuries caused by medical devices is high.

The existing medical protective mask has the advantages that the bendable plastic material adopted at the nose clip is high in hardness, the surface area of the frenulum contacting the skin is small, the pressure is high, the protective mask needs to be taken down once after one hour to two hours, the pressure of the skin compression part is relieved, but the skin (the nose wing part, the face part, the back of the ear and the top of the head) stressed by the protective mask is easy to suffer from ischemic necrosis due to strong infectivity of diseases and long working time of medical staff, the problem that the visual field is affected by fogging of the lens after the goggles are worn is caused, the operation is inconvenient and the like, meanwhile, the possibility that the protective mask is not tightly worn and the skin is not tightly attached is caused, the airtightness is poor, and novel coronavirus is sucked from the gap to cause infection.

Secondly, in the process of resisting the novel coronavirus infection pneumonia, wearing and taking off the protective clothing is a necessary basic operation technology for medical workers, but the process of wearing and taking off the protective clothing is complicated, the operation steps are multiple, a medical protective mask needs to be worn firstly in the first step of wearing the protective clothing, a disposable aseptic cap needs to be worn in the second step, medical goggles need to be worn in the third step, the medical protective clothing needs to be worn again, and the like; twenty complex steps such as medical protective clothing, medical protective mask goggles and the like need to be taken off when coming out from a polluted ward, and the operation is improper during the procedure, so that the risk of potential pollution of medical staff is caused.
