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.

2. A method of blocking readings by a noninvasive optical physiological sensor, the method comprising:
-
providing a sensor cover comprising; a first cover portion attachable to the sensor and configured to block certain wavelengths of light to reduce a likelihood of a false measurement by the sensor when the sensor is active; and a second cover portion that protrudes from the sensor to facilitate removal of the sensor cover; and removably attaching the sensor cover to the sensor, 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. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)
