Example Embodiment

[0014] The hood and body airtight cover can be made of airtight medical plastic. The visual field window can be made of plexiglass or transparent medical plastic to be tightly sealed with the hood, or the whole hood can be made of transparent medical plastic. The check valve is set in The forehead of the hood is better. When the guard enters the contaminated area, connect the hose to the indoor and outdoor air source port, or directly connect the hose to the equipped compressed air bottle, and the hood and body airtight cover follow the exhalation Or the inhalation air pressure changes, adjusted by the pressure reducing valve, so that the air pressure is maintained between 0-50mm water column, to ensure that the hood and body airtight cover always maintain positive pressure.

[0015] The adhesive film of the check valve adopts medical latex film. When the human body inhales, the adhesive film completely covers and seals the outlet of the inner exhaust hood, and the airway is block...

Abstract

A positive-pressure ventilating whole-body isolation system for preventing the respiratory infection of infectious disease features that a check valve is arranged at upper half of sealed helmet, a flexible air inlet tube is connected between compressed air source and the sealed helmet and sealed clothing of body, said helmet has a transparent window for eyes, and said sealed clothing has exhaust holes. Its advantages are good ventilation and now ay that bacteria come in the isolating clothing.

Description

Technical field: [0001] The invention belongs to the technical field of health protection. Background technique: [0002] At present, although the clinical medical staff who are in direct contact with SARS patients are all wearing protective clothing, and the existing protective clothing can apparently isolate the medical staff from the polluted environment, but there is a fatal shortcoming that the medical staff still need to breathe. Although the air in the polluted environment has been improved in the structure or number of layers of the mask, due to the high density of viruses in the polluted area, the need for medical staff to work in the polluted area for a long time, and the strong infectivity of the SARS virus, many Medical staff were cross-infected. Invention content: [0003] The technical problem to be solved by this invention is: [0004] Provide a positive pressure ventilation whole-body isolation system in which the breathing air source of the person to be ...
