Non-invasive physiological sensor cover
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.
1. A method of providing a sensor cover for a noninvasive physiological sensor, the method comprising:
providing 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 a used adhesive layer of a noninvasive physiological sensor comprising sensing components including a light-emitting component and a light-detecting component;
a second adhesive layer formed on a second side of the opaque substrate, the second adhesive layer configured to allow coupling of the noninvasive physiological sensor to a patient;
a window formed on the opaque substrate, the window aligned over the light-detecting component of the noninvasive physiological sensor, wherein the window allows light to reach the light-detecting component; and
an opaque adhesive cover, wherein the opaque adhesive cover overlays the second adhesive layer and the window, the opaque adhesive cover preventing the light-detecting component from detecting light in a first configuration; and
attaching the sensor cover to the used adhesive layer of the noninvasive physiological sensor, the noninvasive physiological sensor cover removable from the sensor,
wherein, in the 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, and
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.
2. The method of claim 1 , wherein the removable portion of the sensor cover in the second configuration comprises the opaque adhesive cover.
3. The method of claim 1 , wherein the window comprises a light-permeable material.
4. The method of claim 1 , wherein the window comprises a cutout of the opaque substrate.
5. A sensor cover for a noninvasive physiological sensor, the 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 a used adhesive layer of a noninvasive physiological sensor comprising sensing components including a light-emitting component and a light-detecting component;
a second adhesive layer formed on a second side of the opaque substrate, the second adhesive layer configured to allow coupling of the noninvasive physiological sensor to a patient;
a window formed on the opaque substrate, the window aligned over the light-detecting component of the noninvasive physiological sensor, wherein the window allows light to reach the light-detecting component; and
an opaque adhesive cover, wherein the opaque adhesive cover overlays the second adhesive layer and the window, the opaque adhesive cover preventing the light-detecting component from detecting light in a first configuration,
wherein, in the 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, and
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.
