Method And System For Self Regulation Of Sensor Component Contact Pressure
First Claim
1. A sensor, comprising:
- a light emitting component comprising a first patient-contacting surface and a first opposing surface;
a light detecting component comprising a second patient-contacting surface and a second opposing surface and capable of detecting light energy emitted by the light emitting component incident upon the second patient-contacting surface;
a backing layer; and
a generally collapsible material positioned generally between the backing layer and at least one of the first opposing surface or the second opposing surface, wherein the generally collapsible material maintains a pressure above a first threshold when not collapsed and collapses to maintain pressure below a second threshold when the sensor is applied.

Abstract
A method and system for regulating contact pressure of a sensor is provided. In accordance with an embodiment, a sensor includes a collapsible material capable of regulating the localized component contact pressure exerted on a tissue between a threshold which ensures proper contact between the sensing component and monitoring site but which minimizes incidents of excessive localized pressures which could result in tissue damage over prolonged use. This localized contact pressure range is maintained over a wide range of sensor application pressures. In one embodiment, a window is provided in the sensor and a colorimetric indication of the compression or expansion of the collapsible material may be determined through the window.
