Biochemical protective hood

Abstract

The invention discloses a biochemical protective hood which comprises a transparent protective hood, a retaining cap, a control and filtering device, and a waistband; an exhaust pipeline is arranged on the top of the transparent protective hood; the retaining cap and the transparent protective hood are rotatably connected through a free ball and a spheroidal groove matched with each other; the control and filtering device comprises a shell; an air intake cavity and an air discharging cavity are formed in the shell; and a sterilizing device is arranged above the shell. The biochemical protective hood has the following benefits: 1, closed type protection is safe and reliable; 2, as the air inflow is greater than the air displacement, the air flowing under the positive air pressure in the protective hood is fresh and does not form fog; 3, the biochemical protective hood realizes modular type multimedium filtering, and is wide in protective usage and high in filtering precision; 4, the free ball enables the hood and the retaining cap to move freely so as to provide excellent technical support for a working staff during operation; 5, an ultraviolet flat sterilizer is arranged to ensurethat the air entering the protective hood is absolutely safe; and 6, the action of the free ball enables the free movement of the protective hood and the retaining cap not to interfere with each other.

Description

technical field [0001] The invention belongs to the technical field of biochemical protection devices, and in particular relates to a biochemical protection head cover. Background technique [0002] The 2019 novel coronavirus, tentatively named 2019-nCoV coronavirus, is a new strain of coronavirus discovered in humans in 2019. Symptoms of the virus are generally fever, fatigue, dry cough, and gradual dyspnea. In severe cases, acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and coagulation dysfunction. Human-to-human transmission of the virus has been confirmed, and the incubation period is contagious. In the medical ward with high density of bacteria and viruses, close-range safety protection of medical staff is very necessary. The existing means of protection for personnel are usually wearing multi-layer masks, multi-layer protective clothing and goggles. However, several layers of protection Masks, airtight protective c...

Problems solved by technology

In the medical ward with high density of bacteria and viruses, close-range safety protection of medical staff is very necessary. The existing means of protection for personnel are usually wearing multi-layer masks, multi-layer protective clothing and goggles. However, several layers of protection Masks, airtight protective clothing, and sweat mist make the already difficult operation worse. These protective equipment have great protection risks and inconvenience in work, which has brought great inconvenience to medical staff. and injury and life safety
