Medical positive pressure breathing hood

Abstract

The invention provides a medical positive pressure breathing hood, and belongs to the field of medical product manufacturing. The medical positive pressure breathing hood comprises a spherical transparent hood body, an air inlet pipe and an exhaust baffle; a wearing opening is formed in the bottom of the transparent hood body, a sealing skirt plate is arranged at the edge of the wearing opening, the exhaust baffle is installed at the top of the transparent hood body, a filtering net is arranged in the exhaust baffle, a dispersion pipe is arranged in the transparent hood body, a plurality of air inlet nozzles facing the human nose and mouth are formed in the dispersion pipe, one end of the air inlet pipe is inserted into the transparent hood body, and an air inlet fan is arranged at the other end of the air inlet pipe; and the air inlet pipe is inserted into the transparent hood body and is connected with the dispersion pipe. According to the medical positive pressure breathing hood, the introduced air is sprayed at the human mouth and nose, breathing is more fresh and natural, the water mist corresponding to the face on the transparent hood body can be effectively dried to avoid blocking the sight; and in addition, the exhaust gas generated by the medical positive pressure breathing hood is discharged through the top of the transparent hood body, and the heat in the hood can betaken away.

Description

technical field [0001] The invention relates to medical device manufacturing technology, in particular to a medical positive pressure breathing hood, which belongs to the technical field of medical product manufacturing. Background technique [0002] Severe infectious diseases, especially infectious diseases that can be transmitted through the air or contact (such as SARS and Ebola, etc.), always pose a threat to human society. Since front-line rescuers need direct contact with pathogens, wearing protective equipment is particularly important to protect the safety of personnel. As a kind of respiratory and contact protective equipment, the positive pressure protective hood can provide a much higher protection factor than ordinary masks and hoods. It can not only completely isolate personnel from the polluted environment, but also provide a clean environment for the interior by purifying the ambient air. Flowing air for greater safety and comfort. [0003] However, most of ...
