1. A partially opaque sensor cover for use with a pulse oximeter sensor, the partially opaque sensor cover comprising:
- a partially opaque portion attachable to the sensor and configured to block optical readings by the sensor; and
a tab portion that protrudes from the sensor to facilitate removal of the partially opaque sensor cover,wherein the sensor comprises;
a light source configured to emit light from one or more emitters of the sensor; and
a detector configured to receive at least a portion of the light emitted by the one or more emitters after the light has passed through a tissue site, andwherein the partially opaque portion at least partially prevents the detector from receiving light during sensor activation.

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.

8. A method of blocking readings by a pulse oximeter sensor, the method comprising:
-
providing a removable sensor cover comprising; a first portion attachable to the sensor, the first portion covering optical components of the sensor such that the first portion reduces the likelihood that the sensor will generate a false measurement when the sensor is active and not proximate a physiological measurement site; and a tab portion that protrudes from the sensor to facilitate removal of the removable sensor cover; and attaching the removable sensor cover to the sensor, wherein the optical components of the sensor comprise; a light source configured to emit light from one or more emitters of the sensor; and a detector configured to receive at least a portion of the light emitted by the one or more emitters after the light has passed through a tissue site. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A sensor cover for use with a pulse oximeter sensor, the sensor cover comprising:
-
a rectangular planar portion that extends beyond at least one border of a pulse oximeter sensor to provide a tab; and an additional portion configured to cover optical components of the sensor when adhesively coupled to the sensor, wherein the sensor cover is configured to reduce a likelihood of a false measurement by at least partially preventing light from reaching a detector of the optical components when the sensor is active but not proximate a measurement site, and wherein the sensor cover is configured to be removed to no longer cover the optical components when the sensor is proximate the measurement site. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
