NONINVASIVE PHYSIOLOGICAL SENSOR COVER
First Claim
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 configured to cover the noninvasive physiological sensor in a first configuration;
the sensor cover comprising a pattern with a dark portion preventing, in the first configuration, measurement of one or more physiological parameters by the noninvasive physiological sensor while the noninvasive physiological sensor is active; and
wherein the removal 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 noninvasive 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. In certain embodiment, the sensor cover has a pattern that allows it to be more easily seen on a surface such as a floor. Further, embodiments of the sensor cover prevent contamination of the sensor. Additionally, embodiments of the sensor cover can prevent damage to the sensor.

15. A method of preventing a noninvasive physiological sensor having a detector for measuring a physiological variable, the method comprising:
-
providing a sensor cover with a pattern, the pattern configured to block light; and attaching the sensor cover to the noninvasive physiological sensor, the pattern covering the detector to prevent the detector from receiving light, wherein blocking the light prevents the detector from taking a measurement, and the sensor cover removable from the detector. - View Dependent Claims (16, 17, 18, 19, 20)
