Patent Images
1. A sensor covering system for a noninvasive optical physiological sensor, the sensor covering system comprising:
- a noninvasive optical physiological sensor comprising;
sensing components including a light-emitting component and a light-detecting component;
a flexible substrate; and
an adhesive layer formed on a side of the flexible substrate; and
a sensor cover comprising;
a cover portion configured to cover at least one of the sensing components while the noninvasive optical physiological sensor is active so as to block light from the one or more emitters from being received by the detector, the cover portion being at least partially opaque,wherein the cover portion is configured to attach to the adhesive layer of the noninvasive optical physiological sensor,wherein at least a portion of the cover portion protrudes from the noninvasive optical physiological sensor and extends past the noninvasive optical physiological sensor to facilitate removal of the sensor cover, andwherein the sensor is a pulse oximeter sensor.

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.
