Patent ID: 7476131

Claim:
A pulse oximetry cable assembly comprising: a cable having a first pair of wires and a second pair of wires, wherein the first and second pairs of wires are surrounded by an outer shield and the second pair of wires are surrounded by an inner shield; and an insulative piece, wherein the insulative piece comprises a printed circuit board configured to maintain spatial separation between the first and second pairs of wires, the insulative piece comprising: a first side and a second side, wherein the first pair of wires are coupled to conductive members located on the first side of the insulative piece and the second pair of wires are coupled to conductive members located on the second side of the insulative piece, the conductive members comprising solder pads and traces coupled to the solder pads, wherein the traces and solder pads are configured to spatially separate the first pair of wires from the second pair of wires, the traces being configured to route emitter signals carried on the first pair of wires away from detector signals carried on the second pair of wires; and inner shield traces and outer shield traces, wherein the inner shield is coupled to the inner shield traces and the outer shield is coupled to outer shield traces, the inner shield traces being configured to encompass detector contacts on the printed circuit board and the outer shield traces being configured to encompass emitter contacts on the printed circuit board.
