1. A sensor, comprising:
- a sensor body comprising a first portion and a second portion, wherein at least one of the first portion and the second portion comprises an alignment feature;
at least one sensing element disposed on the sensor body; and
a sliding clip adapted to slide along the sensor body to bias the first portion towards the second portion, wherein the sliding clip is adapted to apply a pressure to a patient'"'"'s tissue sufficient to overcome the patient'"'"'s venous blood pressure but not sufficient to overcome the patient'"'"'s arterial blood pressure, and wherein the sliding clip is generally U-shaped and configured to be disposed along the alignment feature.

Abstract
A clip-style sensor is provided that includes a sliding clip, such as a flat spring that slides along the sensor to provide a closing force for the sensor. When the sliding clip is engaged, the sensor is secured to the patient. The sensor may be placed on a patient'"'"'s finger, toe, ear, and so forth to obtain pulse oximetry or other spectrophotometric measurements.
