Patent ID: 8333198

Claim:
An oxygen breathing circuit that provides low pressure oxygen, the oxygen breathing circuit comprises: a first tube that is a fluid tight conduit, the first tube includes a distal elbow and a proximal flexible tubular extension, a distal end portion of the elbow includes a distal connector and a proximal end portion of the flexible tubular extension includes a proximal connector, the distal connector is adapted to couple to a proximal end portion of a patent airway maintaining device, the flexible tubular extension has a cross-sectional diameter that does not substantially reduce during flexing, the flexible tubular extension connected to a proximal end portion of the elbow and terminates in the proximal connector, the flexible tubular extension has an abbreviated length, the elbow, proximal connector and distal connector fabricated of a medical grade non-metallic material, the flexible tubular extension connected to the elbow and the second connector; a second tube connected to the first tube, the second tube has a first terminal end external to the first tube and an opposed second terminal end that is in proximity to the first connector; a breathing bag that couples to the second connector and is in fluid communication with the patent airway maintaining device, the breathing bag includes a pressure release valve; and a third tube that couples an external source of oxygen to the second tube, the external source of oxygen supplying low pressure oxygen to the first tube, the first tube, second tube and third tube constructed for low flow resistance.
