Abstract
In some examples, a sensor holder device is described. The sensor holder device may include a rigid body, a set legs attached to the rigid body, a sensor guiding structure, a sensor retaining structure, and an electrical trace. The sensor retaining structure may be sized to accommodate a sensor wire. The electrical trace may extend proximate the sensor retaining structure and along one of the legs.
Claims15
A biosensor holder device, comprising:
- a body;
- a set of printed circuit board (PCB) mounting features attached to the body and extending from one side of the body;
- a sensor guiding opening on a side of the body, wherein the body comprises a groove that extends from the sensor guiding opening and is sized to accommodate a sensor;
- and
- an electrically conductive material extending between the groove and a distal end of a first PCB mounting feature of the set of PCB mounting features,
- wherein the sensor guiding opening is configured to receive a first portion of the sensor and guide the first portion of the sensor below the body and into the groove,
- wherein the groove is configured to retain a second portion of the sensor below the body, and
- wherein the electrically conductive material is positioned in the groove to electrically couple with the second portion of the sensor.

A wearable monitoring device comprising:
- a sensor having a distal portion and a proximal portion;
- a printed circuit board having sensing circuitry mounted thereon;
- a housing containing the printed circuit board and the proximal portion of the sensor, wherein the housing comprises a substantially planar bottom surface to allow the wearable monitoring device to be placed on a person's skin;
- a sensor holder contained inside the housing that is electrically and mechanically coupled to the printed circuit board, the sensor holder comprising a top surface and a bottom surface, wherein the bottom surface faces the substantially planar bottom surface of the housing of the wearable monitoring device;
- a groove in the bottom surface of the sensor holder in which the proximal portion of the sensor is retained;
- electrical contacts associated with the groove electrically interfacing with electrodes on the proximal portion of the sensor, wherein the electrical contacts are electrically coupled to the printed circuit board;
- and
- wherein the distal portion of the sensor is configured to extend substantially perpendicular to the substantially planar bottom surface of the housing into the person's skin, and wherein the sensor bends to extend substantially horizontally inside the housing and into the groove.
