Abstract
An effluent receiver 32 associated with a mask 12 of the type provided with a face portion 22 adapted to be spaced away from the face of the wearer to provide a breathing cavity 26 between the wearer's face and mask. Sealing means 24 associated with the face portion 22 provides a seal to prevent the ingress or egress of gases into or out of the breathing cavity 26. The effluent receiver 32 can be readily assembled to the face protion and is normally associated with a one way valve 42 which prevents the backflow of effluents and/or ambient gases from the receiver 32 to the mask. The parts are so designed that the effluent receiver can be readily assembled. The overall design provides protection for the wearer from ambient gases while permitting a controlled elimination of effluents.
Claims12
A breathing device comprising:
- a face portion which is adapted to be spaced away from the face of a wearer of the breathing device to provide a breathing cavity within the interior of the face portion, said face portion being provided with inlet means for directing breathing gases into said breathing cavity, exhaust means for directing exhaust gases from said breathing cavity, said face portion further including an aperture therein adapted to be located adjacent the chin of the wearer
- sealing means interconnected with the face portion and capable of providing a seal to prevent the ingress of ambient gases into the breathing cavity of the egress of breathing gases from the breathing cavity other than through said inlet means, said exhaust means and said aperture, said sealing means being adapted to contact the bridge of the nose, cheeks, and chin of the wearer;
- a disposable effluent receiver comprising a container having one end removably secured to the exterior of the face portion and fluidically connected to said aperture;
- and
- one-way valve means operatively mounted for permitting effluent material and/or gases to flow in one direction from the breathing cavity into the effluent receiver and for preventing the effluent material and/or gases within the receiver from flowing in the other direction into the breathing cavity.
