Sensor cable support device including mechanical connectors
A sensor cable support device is described. The sensor cable support device can be used to implemented in wearable monitoring device to support a proximal portion of a sensor cable and electrically connect the proximal portion with a sensing circuitry. A distal portion of the sensor cable is insertable into a person's skin. The sensor cable support device may include a rigid body defining a pair of openings, a set legs attached to the rigid body, and a pair of electrical traces extending between the pair of openings and distal ends of a pair of legs of the set of legs. The pair of openings may be sized and configured to receive a pair of pucks that mechanically retain a sensor cable to the body and electrically connect the sensor cable with the electrical traces.
1. A support device for supporting a sensor cable, the support device, comprising:
a rigid body defining a pair of openings, each opening sized and configured to receive a conductive puck, the rigid body configured to support a proximal end of the sensor cable and electrically connect the sensor cable with sensing circuitry of a monitoring device;
a set of rigid legs connected to the rigid body and extending away from bottom side of the rigid body;
a first electrical trace electrically connecting a first opening of the pair of openings and a distal end of a first leg of the set of rigid legs; and
a second electrical trace electrically connecting a second opening of the pair of openings and a distal end of a second leg of the set of rigid legs.
2. The support device of claim 1 , wherein the set of rigid legs is integral to the rigid body.
3. The support device of claim 1 , wherein the pair of openings extend through the rigid body.
4. The support device of claim 1 , wherein the rigid body comprises conductive plating within the pair of openings.
5. The support device of claim 1 , wherein the first opening is electrically isolated from the second opening.
6. The support device of claim 1 , wherein:
the rigid body and the set of rigid legs have characteristics of having been formed from a first material using an injection molding technique; and
the first and second electrical traces have characteristics of having been formed using a laser direct structuring technique, the first and second electrical traces comprising a second material.
7. The support device of claim 1 , wherein the rigid body is further configured to position distal end of the sensor cable that is insertable into a person's skin.
8. The support device of claim 1 , wherein a groove is formed on the bottom side of the rigid body or on a top side of the rigid body that is opposite the bottom side, the groove sized and configured to accommodate the sensor cable.
9. The support device of claim 8 , wherein the groove defines:
a first region disposed adjacent to the first opening, the first region having a first cross-sectional area and sized to accommodate a first portion of the sensor cable including a first wire; and
a second region disposed adjacent to the second opening, the second region having a second cross-sectional area and sized to accommodate a second portion of the sensor cable including a second wire, the first cross-sectional area different from the second cross-sectional area.
10. The support device of claim 1 , further comprising an electrical guard structure disposed between the pair of openings.
11. The support device of claim 10 , wherein the electrical guard structure comprises a third electrical trace that extends to a distal end of a third leg of the set of rigid legs.
12. The support device of claim 10 , wherein the electrical guard structure comprises a guard opening formed in the rigid body and extending through the rigid body.
