Problems solved by technology

[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 are cross-infected

Embodiment Construction

[0016] The hood can be made of airtight medical plastic, and the viewing window can be made of plexiglass or transparent medical plastic to be tightly sealed with the hood, or the whole hood is made of transparent medical plastic, and the check valve is located on the forehead of the hood. Well, when the protective personnel enter 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 air pressure in the hood changes with the exhalation or inhalation, through decompression The valve is adjusted to keep the air pressure between 0-50mm water column to ensure that the hood always maintains a positive pressure.

[0017] The film of the check valve adopts medical latex film. When the human body inhales, the film completely covers and seals the outlet of the inner exhaust hood, and the airway is cut off to form the isolation of the gas inside and outside the hood. It is pushed ope...

Abstract

The disposable positive pressure breathing isolation system as one medical protecting apparatus consists of sealed helmet with non-return valve in the upper part, breathing inlet hose to the helmet connected via reducing valve to the oxygen source, eye shield of transparent material in the helmet, and inside self-adhesive layer in the position corresponding to shoulders. The present invention has the beneficial effects of cutting off respiratory tract infection route to the medical workers by means of no use of the pollutant air, matching with available isolating utensils, low cost for being once used only, and making the user comfortable, cool and no fog formed in the eye shield.

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 disposable positive pressure ventilation respiratory isolation system that separates the breathing air source of...
