1. A sensor covering system for a noninvasive physiological sensor, the sensor covering system comprising:
- a noninvasive physiological sensor comprising sensing components including a light-emitting component and a light-detecting component; and
a sensor cover comprising;
an opaque substrate;
a first adhesive layer formed on a first side of the opaque substrate, the first adhesive layer configured to attach to the noninvasive physiological sensor; and
a second adhesive layer formed on a second side of the opaque substrate, the second adhesive layer configured to attach to a tissue site;
wherein, in a first configuration, the sensor cover covers at least one of the sensing components while the noninvasive physiological sensor is active, the sensor cover preventing measurement of one or more physiological parameters by the noninvasive physiological sensor in the first configuration;
wherein the removal of at least a portion of the sensor cover in a second configuration allows the noninvasive physiological sensor to actively measure the one or more physiological parameters in the second configuration.

Abstract
A sensor cover according to embodiments of the disclosure is capable of being used with a non-invasive physiological sensor, such as a pulse oximetry sensor. Certain embodiments of the sensor cover reduce or eliminate false readings from the sensor when the sensor is not in use, for example, by blocking a light detecting component of a pulse oximeter sensor when the pulse oximeter sensor is active but not in use. Further, embodiments of the sensor cover can prevent damage to the sensor. Additionally, embodiments of the sensor cover prevent contamination of the sensor.
