SYSTEM AND METHOD FOR REDUCING MOTION ARTIFACTS IN A SENSOR
First Claim
1. A sensor, comprising:
- a sensor body; and
a generally low-friction coating on an exterior surface of the sensor body;
wherein the exterior surface is configured to be placed away from a tissue of a patient, and wherein the low-friction coating comprises a material having a coefficient of static friction of generally less than one (1) with respect to cotton, linen, and/or hemp, and/or combinations thereof.

Abstract
Embodiments disclosed herein may include a patient sensor which has a low-friction exterior coating. In an embodiment, the exterior surface of the sensor may come into contact with external items, such as, for example, bed linens, clothing, unintended parts of the patient'"'"'s body, or other people. The low-friction coating disposed on the exterior of the sensor may include a material having a relatively low coefficient of friction with respect to these external items. In an embodiment, the low-friction material may include, for example, a fluoropolymer, a polypropylene, or a polyethylene. Additionally, in an embodiment, an internal surface of the sensor that is in contact with the patient may have a relatively high-friction coating, such as an adhesive. In an embodiment, a stack of adhesive layers may be disposed on the internal surface around one or more light emitting and/or detecting optics.
