Hat-based oximeter sensor
View Patent ↗A method for use and an improved oximeter sensor substrate that is conforming to the shape of the patient's forehead. In one embodiment, the present invention is an oximeter sensor, having a substrate with a shape similar to a shape of at least a portion of a patient's forehead and including a section adapted to substantially fit over a portion of a forehead of a patient; an emitter disposed on the substrate at a position located on the section; and a detector disposed on the substrate at a distance from the emitter. In one embodiment, the substrate includes a hat that holds the emitter and the detector in a spaced-part manner against the patient's forehead.
1. A pulse oximetry sensor comprising:
a stocking cap;
a substrate disposed on the stocking cap;
an emitter disposed on the substrate;
a detector disposed on the substrate; and
a cable disposed on the substrate, wherein the cable extends from the substrate at an angle not in-line with an imaginary axis extending through the emitter and the detector, and wherein the cable extends through an open portion of the stocking cap configured to be proximate to a top of the stocking cap when the stocking cap is applied to the patient.
2. The sensor of claim 1 , wherein the cable is disposed on the substrate in a substantially orthogonal direction relative to the axis.
3. The sensor of claim 1 , wherein the cable is disposed on the substrate such that the cable substantially bisects the emitter and the detector.
4. The sensor of claim 3 , wherein the substrate comprises a T-shape.
5. The sensor of claim 1 , wherein the sensor is adapted to operate in a reflectance mode.
6. The sensor of claim 1 , wherein the substrate is adapted to be used on a patient's forehead.
7. The sensor of claim 1 , wherein the stocking cap comprises a neonatal stocking cap.
8. The sensor of claim 1 , wherein the substrate comprises an adhesive layer adapted to attach the substrate to the headcovering.
9. A headcovering comprising:
a neonatal stocking cap; and
a pulse oximetry sensor, wherein the pulse oximetry sensor comprises:
a substrate;
an emitter disposed on the substrate;
a detector disposed on the substrate; and
a cable disposed on the substrate, wherein the cable extends from the substrate through an open portion of the neonatal stocking cap configured to be proximate to a top of the neonatal stocking cap when the neonatal stocking cap is applied to the patient.
10. The sensor of claim 9 , wherein the substrate is conformable to a forehead-contacting surface of the headcovering.
11. The sensor of claim 9 , wherein the substrate is adapted to be attached to the headcovering.
12. The sensor of claim 9 , wherein the substrate comprises an adhesive layer adapted to attach the substrate to the headcovering.
13. The sensor of claim 9 , wherein the cable is secured by a portion of the neonatal stocking cap.
