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.
