Patent ID: 7548771

Claim:
A pulse oximetry sensor adapted for use on a patient's digit, wherein the patient's digit includes a distal portion having a distal bone covered with skin and tissue and wherein the distal portion has a length L as measured from a tip of the digit to a transverse fold of skin located generally at a joint between the distal bone and an adjacent bone, the pulse oximetry sensor comprising: an emitter and a detector adapted to be located on a distal region of the distal portion of the patient's digit when the sensor is properly applied to the patient's digit, wherein the distal region is measured as extending from the tip of the distal portion to a location spaced no more than approximately 30% of the length L from the tip, and wherein approximately 30% of the length L is in the range of approximately 5-7 mm; and a clip-style sensor in which the emitter and detector are disposed, wherein the clip-style sensor is configured such that the tip of the patient's digit abuts a stop within the clip-style sensor when the sensor is properly applied to the patient's digit.
