Abstract

A reusable sensor is disclosed for producing a signal indicative of at least one physiological parameter of tissue. The sensor can include a sensor housing that has a distal opening, a wire lumen, and a proximal opening. The distal opening can include a lumen extending through the body of the sensor housing and the wire lumen can be located on the outside of the sensor housing. The sensor can also include a first component located on a top surface of the sensor housing and along the pathway of the wire lumen. The sensor can also include a second component located on the bottom surface of the sensor housing opposite of the first component. The second component can also be located along the pathway of the wire lumen. The sensor can also include a wire coaxially disposed within the wire lumen and connecting the first component and second component.

Claims

1. A reusable sensor for measuring a signal indicative of at least one physiological parameter of tissue, the sensor comprising:

a reusable circuit including one or more light emitting source configured to emit light of at least two different wavelengths and at least one light detector configured to detect the light after it has been attenuated by body tissue;

an elastomer sensor housing comprising a finger lumen sized and shaped to fit a finger, the sensor housing having a distal opening and a wire lumen;

wherein the sensor housing is disposed about a portion of the one or more light emitting source and the at least one light detector and configured to surround and enclose a finger,

wherein the sensor housing includes an opening on a top surface of the sensor housing configured to allow a portion of the emitted light to be visible from the top surface of the sensor housing, and

wherein the wire lumen that extends through the body of the sensor housing, along a topside of the sensor housing; and

a wire, wherein the wire is disposed within the wire lumen and provides a connection between the light emitting source and the light detector.

2. The reusable sensor of claim 1, wherein the sensor housing has a rubber or an elastomeric material.

3. The reusable sensor of claim 1, wherein the wire lumen and the wire have a portion that deviates from a centerline of the sensor at an angle that is between 1 and 45 degrees.

4. The reusable sensor of claim 1, wherein the wire lumen is contained within the sensor housing.

5. The reusable sensor of claim 1, wherein the wire lumen extends from the sensor housing.

6. The reusable sensor of claim 1, wherein a proximal opening is internally connected with a proximal end of the finger lumen.

7. The reusable sensor of claim 1, wherein a top and bottom surface of the sensor housing is compressed at a proximal end of the sensor.

8. The reusable sensor of claim 1, wherein the detector is located on a bottom portion of the sensor housing and protrudes from the sensor housing.

9. The reusable sensor of claim 1 wherein an emitter is located on a top portion of the sensor housing.
