1. An apparatus comprising:
- a stocking cap capable of being applied to a patient'"'"'s head;
a substrate disposed adjacent the stocking cap;
a light emitter disposed on the substrate;
a light detector disposed on the substrate;
a cable disposed on the substrate, wherein the cable extends from the substrate through an open portion of the stocking cap configured to be proximate to a top of the stocking cap when the stocking cap is applied to the patient; and
a compressible protrusion disposed on the substrate, wherein the compressible protrusion is configured to substantially surround at least one of the emitter or the detector.

Abstract
According to various embodiments, a medical sensor assembly may include compressible light barriers configured to prevent undesired light from being detected. The compressible light barriers may protrude from the surface of the sensor. However, when applied to the tissue, the compressible light barriers may be compressed to the point of being substantially flush with the tissue.

13. A pulse oximetry system comprising:
-
a pulse oximetry monitor; and a sensor assembly capable of being operatively coupled to the monitor, the sensor assembly comprising; a light emitter and a light detector disposed on a substrate; a compressible protrusion disposed on the substrate in an area between the emitter and the detector, wherein the compressible protrusion does not substantially exsanguinate the patient'"'"'s tissue when the sensor is assembly is applied to a patient'"'"'s tissue; and a cable disposed on the substrate, wherein the cable is configured to be coupled to the monitor. - View Dependent Claims (14, 15, 16, 17, 18)

19. A sensor comprising:
-
a sensor body adapted to operate in a reflectance mode; an emitter disposed on the sensor body, wherein the emitter is configured to deliver a first light into a tissue; a detector disposed on the sensor body, wherein the detector is configured to detect the first light; and a compressible protrusion disposed on a tissue-contacting surface of the substrate, wherein the compressible protrusion is configured to reduce the amount of a second light impinging the detector at an incident angle substantially in-line with an imaginary axis connecting the emitter and the detector, and wherein the compressible protrusion has a compression modulus of less than about 2.0. - View Dependent Claims (20, 21, 22, 23, 24, 25)
