First Claim
Patent Images
1. A physiological sensor assembly, comprising:
- a physiological sensor having at least one light source and at least one optical receiver; and
a substantially transparent to near infrared light barrier layer having a first surface and an opposing second surface, said first surface configured to removably adhere to a patient'"'"'s skin and said second surface configured to removably adhere to the sensor,wherein said barrier layer is configured to allow moisture from the patient'"'"'s skin to pass through the second surface when said sensor is disposed on said barrier layer.

Abstract
A physiological sensor assembly includes a physiological sensor having at least one light source and at least one optical receiver. A substantially transparent barrier layer is disposed between the physiological sensor and the patient'"'"'s skin such that the barrier layer is removably adhered to the physiological sensor and removably adhered to the patient'"'"'s skin.

9. A physiological sensing system, comprising:
-
a physiological sensor having at least one near-infra red light source and at least one optical receiver; a controller/display unit in signal communication with said physiological sensor; and a substantially transparent, non-occlusive film that is removably affixed to said physiological sensor and removably affixed to a patient'"'"'s skin; wherein said film has a surface area larger than a surface area of said physiological sensor to allow moisture from the patient'"'"'s skin to pass through a surface of said film opposite the patient'"'"'s skin when said film is adhered to said patient'"'"'s skin and said sensor is adhered to said film. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A physiological sensor comprising:
-
a sensor pad; at least one light source disposed on the sensor pad; at least one optical receiver disposed on the sensor pad and configured to detect light emitted by the at least one light source; and a non-occlusive barrier layer having a first surface and an opposing second surface, said first surface configured to removably adhere to a patient'"'"'s skin and said second surface configured to removably adhere to the sensor pad, and wherein said barrier layer is configured to allow moisture from the patient'"'"'s skin to pass through the second surface of the barrier layer when the barrier layer is adhered to the patient'"'"'s skin and sensor pad is adhered to the barrier layer. - View Dependent Claims (17, 18, 19)
