Description

Shoulder-carried reusable filter for sterilizing and breathing gas for medical staff

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a shoulder-carried reusable filter for inhaled gas disinfection and exhaled gas for medical staff.

Background

In the process of preventing and resisting infectious diseases of the respiratory system, the main measures are as follows:

the method comprises the following steps of: once the epidemic situation is discovered, the virus propagation path is blocked by rapidly adopting the conditions of home, distance between people, shutdown and production halt, no trip and even city sealing, but the economic loss is huge.

The environment is eliminated and killed: the disinfectant is sprayed to rooms, restaurants, places, streets and the like to kill viruses attached to objects and air so as to kill infectious sources, but the space for killing the environment is limited, and the effect is not thorough.

Vaccine injection and drug: the antigen produced by the inactivated virus is injected into human body to stimulate the immune system of the body to produce antibody, so that the human body can generate immunity to the virus invading into the human body without being damaged. Although the method is effective, firstly, the time for preparing the vaccine is long, and most of the vaccine is completely prepared and hardly plays a real role in time; secondly, the variation of the virus is rapid, so that the single target point and the single action mechanism of the vaccine and the western medicine have limited effect.

Fourth, protecting the mask: in the field of prevention and treatment of infectious diseases of the respiratory system, the way of wearing the mask is the most common, practical and effective method at present. However, the method only blocks the transmission path of the virus, but cannot directly kill the virus, especially for the near-body personnel of the patient, the virus is only blocked outside the mask or the protective clothing, and the risk of infection caused by virus breakthrough protection still exists even if the mask or the protective clothing is carelessly damaged. In the epidemic prevention process, tens of thousands of medical staff are infected and hundreds of medical staff are responsible, which indicates that the incidence rate of infection prevention of the mask and the protective clothing is not 100%. Moreover, the mask is disposable, short in service time and large in consumption.

Recent studies have considered that conventional mask products are neither economical nor environmentally friendly, and the ideal solution is to develop a recyclable mask. The purpose is realized by researching and developing a novel charging mask by scientific research personnel of Israel institute of technology. The charging mask is similar to the common N95 mask in appearance, and is reported by the Lu Tuo corporation in 2020, 6 months and 17 days. Once the power supply is connected, the heating device in the mask can raise the surface temperature of the mask to 70 ℃, and after half an hour, bacteria and viruses on the surface of the mask can be killed and eliminated at high temperature, but cannot be used during charging.

The charging disinfection mask is mainly used for solving the problem of repeated use, cannot be used in an electrified mode, can seriously scald the skin, and still has no disinfection effect during wearing. Therefore, the effect of preventing virus infection is still to block the transmission path and can not kill virus during wearing the mask. There is still a risk of infection to medical personnel examining and treating infected patients.

In summary, at present, there are some defects and deficiencies in the measures for preventing respiratory infectious diseases at home and abroad, especially for the near-body personnel of patients. The research adopts the method of disinfecting the inhaled air and filtering the exhaled air for medical staff, effectively kills infectious viruses and simultaneously effectively filters the exhaled air, thereby playing the roles of effectively killing viruses, blocking the transmission path and preventing the medical staff from being infected.
