Abstract

Claims (24)

1 . A sensor cable comprising:

a conductor set of insulated wires, each of the insulated wires in the sensor cable comprising a conductive core disposed within an insulation layer;

a drain line;

an inner jacket extending immediately around the insulation layer of each of the insulated wires in the sensor cable and the drain line, the inner jacket having flat surfaces on at least two elongated sides of the inner jacket; and

an outer jacket extending around the inner jacket, the outer jacket having a flat outer surface on at least two elongate sides of the outer jacket,

wherein one of the at least two elongated sides of the outer jacket has no more than one groove formed on its flat outer surface, the no more than one groove extending along an entire length of the outer jacket and along a center of the flat outer surface on the one of the at least two elongated sides of the outer jacket, the no more than one groove comprises a flat bottom and two walls, the two walls having planar sections that are slanted relative to the flat bottom,

wherein at least two wires of the conductor set are positioned between the flat outer surfaces on opposite sides of the inner jacket; and

a flex circuit comprising a plurality of pads configured to electrically connect to a sensor, the plurality of pads comprising at least three pads that are linearly arranged and regularly spaced, the conductor set and the drain line being soldered at first ends to the plurality of pads.

2 . The sensor cable of claim 1 , in combination with the sensor, the sensor being electrically connected to the plurality of pads and comprising an emitter configured to emit light and a detector configured to detect the light after attenuation by tissue.

3 . The sensor cable of claim 1 , in combination with the sensor, the sensor being electrically connected to the plurality of pads and comprising an emitter configured to emit light and a detector configured to detect the light after attenuation by tissue, the sensor being configured to wrap around a fingertip of a user.

4 . The sensor cable of claim 1 , in combination with the sensor, the sensor being electrically connected to the plurality of pads and configured to receive a control signal from a first wire of the conductor set and transmit a data signal to a second wire of the conductor set via the plurality of pads, the control signal being configured to control an operation of the sensor, the data signal comprising sensor data generated by the sensor.

5 . The sensor cable of claim 1 , wherein the conductor set includes a total of at least four wires.

6 . The sensor cable of claim 1 , wherein the conductor set and the drain line are configured to electrically connect to a patient monitor at second ends of the conductor set and the drain line opposite to the first ends.

7 . The sensor cable of claim 1 , wherein the drain line is configured to drain electrical charge from the inner jacket.

8 . The sensor cable of claim 1 , wherein the drain line is not surrounded by a wire insulation like the wire insulation that generally surrounds each wire of the conductor set.

9 . The sensor cable of claim 1 , wherein wire insulations of the conductor set are color coded to separately visually identify individual wires of the conductor set from one another.

10 . The sensor cable of claim 1 , wherein a first wire of the conductor set and a second wire of the conductor set are positioned within the inner jacket at a common distance from the no more than one groove.

11 . The sensor cable of claim 1 , wherein the inner jacket and the outer jacket comprise PVC.

12 . The sensor cable of claim 11 , wherein the inner jacket comprises co-extruded conductive PVC, and the outer jacket comprises semi-pressure extruded PVC.

13 . The sensor cable of claim 11 , wherein the inner jacket is conductive.

14 . The sensor cable of claim 1 , wherein the conductor set and the drain line are electrically connected to the plurality of pads on a common side of the flex circuit.

15 . The sensor cable of claim 1 , wherein the plurality of pads comprise at least four pads that are linearly arranged and regularly spaced.

16 . The sensor cable of claim 1 , wherein the two walls are symmetrical relative to the flat bottom.

17 . The sensor cable of claim 1 , wherein the plurality of pads are electrically connected to the sensor.
