Abstract:

A breathing apparatus is operable in self-contained and filtered modes of operation. In the self-contained mode of operation, a breathable gas is delivered to a user from a self-contained source of breathing gas. In a second, filtered mode of operation, a suction source draws ambient air through a filter removing contaminants and delivers filtered ambient air to the user. A method of delivering air to a subject is also provided.

Appl. No.:

13/779950

Inventors:

Mark A. HANSEN - Virginia Beach VA, US

Assignee:

The Osen-Hunter Group - Barborsville VA

International Classification:

B23K 7/00

US Classification:

148194, 266 48, 266 66

Abstract:

A system for performing exothermic operations or oxygen delivery uses a rod and handle configuration to create a flowpath of oxygen. The rod includes cables having stainless steel fibers that burn using the oxygen within a hollow center area. While burning, the rod cuts through material. A sheath covers the covers to contain the gases and prevent unraveling of the cables. The handle attaches to the rod and provides control of the flow of oxygen to the rod. A manifold fixing in place bottles of oxygen connects to the handle and can be fixed to provide different mixtures from different bottles. The rod is disconnected when needed to fix a mask thereto for delivering breathable oxygen to a patient.

US Classification:

12820512

Abstract:

A self-contained respiratory protection system is disclosed. The system includes a center module attachable to one or more cylinders of air, gas or oxygen. A plurality of filters is mountable on the center module. A blower motor also may be mounted on the center module. A hose attaches to a cylinder to provide air to an operator or draws filtered air via the filters on the center module. A first stage regulator converts the air in the cylinder to breathable air for the operator. A second stage regulator transitions between filter mode and supplied air. The system may fit within a backpack.
