Abstract

A pedestal for a physiological characteristic sensor assembly and a physiological characteristic sensor assembly is provided. The pedestal includes a first side opposite a second side. The pedestal includes a sidewall that interconnects the first side and the second side. The pedestal also includes a first end opposite a second end. The pedestal includes at least one post that extends from the first side adjacent to the first end to couple the pedestal to a physiological characteristic sensor of the physiological characteristic sensor assembly. The pedestal also includes a recess defined in the sidewall at the second end. The recess has a first portion in communication with a second portion. The first portion has a first length that is less than a second length of the second portion along a perimeter of the sidewall, and the second portion is positionable to apply a force to the physiological characteristic sensor.

First claim

What is claimed is:

1. A physiological characteristic sensor assembly, comprising:
a physiological characteristic sensor including a sensor coupled to a sensor base, the sensor base including a pair of pedestal coupling pockets each defining a plurality of planar surfaces and a pair of introducer coupling slots, each one of the pair of introducer coupling slots in communication with a respective one of the pair of pedestal coupling pockets;
an adhesive patch coupled to the physiological characteristic sensor; and
a pedestal removably coupled to the physiological characteristic sensor, the pedestal including a first side opposite a second side and a first end opposite a second end, with a sidewall that interconnects the first side and the second side and a longitudinal axis defined along the pedestal from the first end to the second end, the pedestal including:
a pair of posts that extend outwardly from a surface of the first side proximate the first end, each of the pair of posts defining a plurality of points of contact to form an interference fit with the sensor base in a first position in which the physiological characteristic sensor is coupled to the pedestal, the pair of posts rotated relative to one another, with each of the plurality of points of contact of each of the pair of posts in contact with a respective one of the plurality of planar surfaces of the pair of pedestal coupling pockets of the sensor base in the first position; and
a removal recess defined through the sidewall at the second end having a first portion in communication with a second portion, the removal recess extends from the first side to the second side along an axis that is perpendicular to the longitudinal axis of the pedestal, the first portion having a first length that is less than a length of the second portion along a perimeter of the sidewall, the first length and the length of the second portion defined perpendicular to the axis of which the removal recess extends, the removal recess defines at least one first contact surface along the first length at the second side and at least one second contact surface along the second length at the second side, and the second portion is configured to be positionable over the sensor base such that the at least one first contact surface and the at least one second contact surface apply a force to the sensor base in a second position in which the physiological characteristic sensor is uncoupled from the pedestal and deployed onto an anatomy.

2. The physiological characteristic sensor assembly of claim 1 , wherein the pair of posts each extend outwardly from the surface of the first side so as to be parallel to the axis of which the removal recess extends.

3. The physiological characteristic sensor assembly of claim 1 , wherein the removal recess is symmetric about the axis of which the removal recess extends.

4. The physiological characteristic sensor assembly of claim 1 , further comprising a sensor introducer coupled to the pair of introducer coupling slots of the sensor base in the first position, the sensor introducer to introduce the sensor into the anatomy.

5. The physiological characteristic sensor assembly of claim 4 , wherein sensor base has a first base side opposite a second base side, the second base side is coupled to the adhesive patch and the first portion of the removal recess is configured to be positionable about the sensor introducer and the second portion of the removal recess is configured to be positionable over the first base side of the sensor base in the second position.

6. The physiological characteristic sensor assembly of claim 1 , wherein the first portion has a first height along the axis of which the removal recess extends and the second portion has a height defined between the first side and the second side of the pedestal along the axis of which the removal recess extends, and the height of the second portion is less than the first height.

7. The physiological characteristic sensor assembly of claim 1 , wherein the first portion has a first width and the second portion has a width defined from a perimeter of the pedestal at the second end, the first width greater than the width of the second portion such that the first portion is indented into the pedestal, with the first width and the width of the second portion perpendicular to the axis of which the removal recess extends.

8. The physiological characteristic sensor assembly of claim 1 , wherein the adhesive patch is couplable to the first side of the pedestal and the adhesive patch defines a pair of coupling bores to receive a respective one of the pair of posts.

9. The physiological characteristic sensor assembly of claim 1 , wherein the physiological characteristic sensor is a glucose sensor.

10. A physiological characteristic sensor assembly, comprising:
a physiological characteristic sensor including a sensor coupled to a sensor base, the sensor base including at least one pedestal coupling pocket defining a plurality of planar surfaces and at least one introducer coupling slot in communication with the at least one pedestal coupling pocket;
an adhesive patch coupled to the physiological characteristic sensor; and
a pedestal removably coupled to the physiological characteristic sensor, the pedestal including a first side opposite a second side and a first end opposite a second end, with a sidewall that interconnects the first side and the second side and a longitudinal axis defined along the pedestal from the first end to the second end, a surface of the first side configured to receive the adhesive patch in a first position in which the physiological characteristic sensor is coupled to the pedestal, the pedestal including:
at least one post that extends outwardly from the surface of the first side near the first end, the at least one post defining a plurality of points of contact configured to form an interference fit with the sensor base in the first position, with each of the plurality of points of contact in contact with a respective one of the plurality of planar surfaces of the at least one pedestal coupling pocket of the sensor base in the first position; and
a removal recess defined through the sidewall at the second end having a first portion in communication with a second portion, the removal recess extends from the first side to the second side along an axis that is perpendicular to the longitudinal axis of the pedestal, the removal recess defines at least one first contact surface along the first length at the second side and at least one second contact surface along the second length at the second side, and the second portion is configured to be positionable over the sensor base such that the at least one first contact surface and the at least one second contact surface apply a force to the sensor base in a second position in which the physiological characteristic sensor is uncoupled from the pedestal and deployed onto an anatomy,
