Abstract

Abstract An arrangement for protecting of organs of respiration has a closing element adapted to close the user's nose and mouth, a filtering element communicating with said closing element so that when the user performs inspiration ambient air passes through said filtering element and is cleaned by the latter to be inspirated in cleaned condition, and a device for urging air to flow to and to pass through the filtering element. The device includes an urging element which is actuated in response to the inspiration performed by the user. The device may be formed as a deformable container which is mounted on the user's thorax so that when the user performs inspiration and the volume of thorax increases, the container is deformed and thereby forcedly urges air to the filtering element. The device may also be formed as an impeller driven by an electric motor which is actuated in response to the user's inspiration. The actuation of the electric motor may be performed by a similar deformable container, or by a flap-type switch actuated under the action of inspiration.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 181 words
An arrangement for protecting organs of respiration, comprising a closing element adapted to close the user's nose and mouth; a filtering element communicating with said closing element so that ambient air can pass through said filtering element to be cleaned therein and thereafter supplied in cleaned condition into said closing element to be aspirated by the user; means for forcedly urging the ambient air to flow and to pass through said filtering element, said means including an urging element actuated in response to the inspiration performed by the user, and formed as a deformable container which has an inner chamber including one way valve means providing one way flow of ambient air into said chamber and an outlet connected with said filtering element; and means for mounting said deformable container on the user's thorax so that when the user performs inspiration and the volume of thorax increases, said container is deformed and the volume of said inner chamber decreases whereby the ambient air which enters said inner chamber of said container is urged to flow to and through said filtering element.
Claim 2
Dependent Claim 181 words
An arrangement for protecting organs of respiration, comprising a closing element adapted to close the user's nose and mouth; a filtering element communicating with said closing element so that ambient air can pass through said filtering element to be cleaned therein and thereafter supplied in cleaned condition into said closing element to be aspirated by the user; means for forcedly urging the ambient air to flow and to pass through said filtering element, said means including an urging element actuated in response to the inspiration performed by the user, and formed as a deformable container which has an inner chamber including one way valve means providing one way flow of ambient air into said chamber and an outlet connected with said filtering element; and means for mounting said deformable container on the user's thorax so that when the user performs inspiration and the volume of thorax increases, said container is deformed and the volume of said inner chamber decreases whereby the ambient air which enters said inner chamber of said container is urged to flow to and through said filtering element.
Claim 3
Dependent Claim 54 words
An arrangement as defined in claim 1; and further comprising a rigid member which is displaced in response to the increases of the volume of the user's thorax, secured to and in abutting relation against said deformable container so as to deform the latter and to thereby reduce the volume of said inner chamber.
