Patent ID: 7900633

Claim:
An oxygen breathing circuit that provides low pressure oxygen to a patient at risk to hypoxia, the oxygen breathing circuit comprises: a patent airway maintaining device; 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 couples to a proximal end portion of the patent airway maintaining device, the flexible tubular extension axially and radially flexible and has a cross-sectional diameter that does not substantially reduce during axial flexing, the flexible tubular extension is fixedly 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 being fabricated of a substantially rigid medical grade non-metallic material, the flexible tubular extension fixedly 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.
