Patent ID: 8797714

Claim:
A patient monitoring system comprising: a patient monitor configured to display information regarding a patient, wherein the patient monitor comprises a first port; a cable comprising a proximal end and a distal end, and further comprising a cable body that extends between the proximal and distal ends, wherein the proximal end of the cable comprises a first connector configured to electrically couple with the first port of the patient monitor; an electrical interface configured to receive analog signals from a patient parameter sensor; and a first circuit including a front-end processing module configured to condition the analog signals from the patient parameter sensor and convert the analog signals into digital signals, wherein the first circuit is external to the patient monitor, wherein the first circuit is closer to the distal end of the cable than it is to the proximal end of the cable when the system is in an assembled state and the cable is fully extended to limit a distance over which the analog signal is transmitted over the cable, and wherein the first circuit is at a distance of no less than about 3.0 feet from the first connector and no more than about 3.0 feet from the distal end when the system is in an assembled state and the cable is fully extended.
