Abstract

An exemplary sensor includes a sensor pad defining a perimeter, a light source, a light detector, and an adhesive layer. The light source is configured to generate near-infrared light and transmit the near-infrared light through part of a patient's body. The light detector is configured to receive the near-infrared light generated by the light source after it has traveled through part of the patient's body. The light received by the light detector indicates an amount of oxygen in the part of the patient's body through which the near-infrared light traveled. The adhesive layer is offset relative to the sensor pad to, for example, allow a clinician to easily remove the sensor from the patient.

First claim

The invention claimed is:

1. A sensor assembly comprising:
a generally planar sensor pad having a perimeter, said sensor pad having a top side and a bottom side wherein said bottom side is configured to be toward a patient's skin and said top side is configured to be away from the patient's skin when said sensor is applied to the patient, and wherein said bottom side is substantially free of adhesive;
a light source disposed on the sensor pad and configured to transmit light thr…
