Abstract

The invention discloses an inflatable conjoined positive pressure hood, which includes a hood body and a gown, the hood body is used to wear on the head of a human body, the gown is sealed and connected to the lower end of the hood body, and the gown is provided with an expansion chamber. The volume of the expansion cavity is adjustable so that the inner wall of the gown fits the human body. The technical solution of the invention can ensure a good sealing effect while making the human body comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to an inflatable one-piece positive pressure hood. Background technique [0002] Positive pressure hood is a kind of breathing and contact protective equipment that isolates the human body from the polluted environment while providing purified flowing air for the interior. It is an important protective equipment for front-line rescuers. In the related art, a one-piece positive pressure hood usually includes a hood body and a gown sealedly connected with the hood body. The gown is worn on the upper body or the whole body of the human body. In order to prevent unpurified air from passing Enter the hood body at other positions, usually set elastic cords or laces on the cuffs and hem, and use the elastic cord or laces to tighten the cuffs and hem to achieve a sealing effect. Sealing in this way, if the degree of tightening is not enough, the sealing effect will be poor; if...
