Optical-based physiological sensor assembly with disposable barrier layer

摘要

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.

1. A physiological sensor assembly, comprising:
a physiological sensor having at least one light source and at least one optical receiver; and a barrier layer that has a first surface and an opposing second surface, said first surface configured to be removably adhered to a patient's skin and said second surface configured to be removably adhered to the sensor; wherein said adhesion of said barrier layer to the skin is configured to be greater than said adhesion of said barrier layer to said sensor; wherein said barrier layer is configured to allow moisture from the patient's skin to pass through the second surface when said barrier layer is adhered to the patient's skin and the sensor is disposed on said barrier layer.
