Medical care channel for atomizing, spraying and disinfecting by using protective gas and disinfectant

Abstract

The invention discloses a medical care channel for atomizing, spraying and disinfecting by using protective gas and disinfectant. The medical care channel is composed of a gate, a box body, an interval sealing isolation plate, a protective gas spraying and recycling system, a disinfectant spraying and recycling system, a channel monitoring room and an intelligent control circuit system, and is suitable for medical workers wearing bubble type positive pressure medical protective clothing to pass. When a pollution area is formed, the medical workers firstly close an electric respirator, start amicro oxygen tank carried in the protective clothing to supply oxygen, and communicate a one-way exhaust valve pipe opening in the protective clothing with a protective clothing one-way exhaust pipe in the channel box body to form an expiration discharge passage independent of the internal space of the sealed channel box body; then the channel system uses nitrogen as the protective gas to spray and discharge oxygen, and uses 70% -75% ethanol as the disinfectant to atomize, spray and disinfect; and finally, the nitrogen is used for spraying and drying, and the sprayed nitrogen and ethanol are synchronously recycled, so that the medical care channel provides support equipment guarantee for improving the safety, comfort and convenience of the medical workers wearing the protective clothing inhospitals.

Description

technical field [0001] The invention relates to the field of medical anti-epidemic equipment, in particular to a medical and nursing channel between a hospital polluted area and a clean area, which uses protective gas and disinfectant for atomized spraying and disinfection. Background technique [0002] In order to treat dozens of severe infectious diseases of Class A and Class B such as novel coronavirus pneumonia, atypical pneumonia (SARS), and human infection of highly pathogenic avian influenza, prevent the virus from passing through air droplets (aerosols), contact, blood, Secretions, excreta, contaminated clothing, etc. are transmitted. Now the infectious disease departments of the hospital are all planned and constructed according to the "three areas and two channels", that is, by setting up two or three access controls, the medical offices, changing clothes, etc. Physically cut off rooms and passages such as rooms and infectious disease rooms to form clean areas, pot...

Problems solved by technology

[0005] 3. It is not suitable for the passage of medical staff wearing air bubble positive pressure medical protective clothing: In order to overcome the shortcomings of existing medical protective clothing, the invention patent No. 202010154267.1 published by the China Patent Office is to solve the current medical The best solution for the safety, comfort and economy (repeatable use) of protective clothing. However, the current medical and nursing channels in the hospital are not equipped with corresponding spray disinfection facilities. of medical staff cannot perform full-body disinfection when they leave the contaminated area

[0006] Due to the above-mentioned limitations of the existing medical and nursing channels, it not only causes a greater workload and pain for the medical staff, but also increases the management difficulty of the hospital's epidemic prevention and safety management, forcing the hospital to use only disposable medical supplies. Protective clothing, resulting in an increase in medical waste, increased environmental pressure, and high costs
