ABSTRACT:
A modified Foley type catheter has a pressure sensor near the insertion end, an inflatable balloon, a temperature sensor, a light emitter, and a blood oxygen level detector near the light emitting means, all molded into the catheter tube wall. The oxygen level sensor is arranged to receive light energy from tissue illuminated by the light source. All required electrical conductors, and fiber optics elements if used, are molded into the catheter wall and terminate in a connector near the access end. The balloon has a fluid supply conduit, or channel, molded into the catheter wall and it terminates in a connector nipple near the access end. A pulse detector means is derived from the association of the oxygen level sensor and the required external signal processor. All associated external signal processor and output indicators means currently exist for observation and recording. Rewiring for suitable connector association with the novel catheter is well established in the art.
