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

We claim:

1 . A pedestal for a physiological characteristic sensor assembly, the pedestal comprising:
a first side opposite a second side, with a sidewall that interconnects the first side and the second side, and a first end opposite a second end; 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; and a recess defined in the sidewall at the second end, the recess having a first portion in communication with a second portion, the first portion having a first length that is less than a second length of the second portion along a perimeter of the sidewall, the first portion having a first height and the second portion having a second height defined between the first side and the second side of the pedestal, the second height less than the first height, and the second portion being positionable to apply a force to the physiological characteristic sensor.

2 . The pedestal of claim 1 , wherein the at least one post comprises two posts that are spaced apart on the first side, and each of the posts have a plurality of sides to couple the pedestal to the physiological characteristic sensor.

3 . The pedestal of claim 1 , wherein the recess extends along an axis that is substantially perpendicular to a longitudinal axis of the pedestal.

4 . The pedestal of claim 3 , wherein the recess is substantially symmetric about the longitudinal axis.

5 . The pedestal of claim 1 , wherein the first portion has a first width and the second portion has a second width, and the first width is greater than the second width.

6 . A pedestal for a physiological characteristic sensor assembly including a physiological characteristic sensor, the pedestal comprising:
a first side opposite a second side, with a sidewall that interconnects the first side and the second side, and a first end opposite a second end, and a longitudinal axis defined along the pedestal from the first end to the second end; at least one post that extends outwardly from a surface of the first side adjacent to the first end to couple the pedestal to a physiological characteristic sensor of the physiological characteristic sensor assembly, the at least one post being configured to form an interference fit with the physiological characteristic sensor in a first position in which the physiological characteristic sensor is coupled to the pedestal; and a recess defined in the sidewall at the second end, the recess having a first portion in communication with a second portion, the recess extending from the first side to the second side along an axis that is perpendicular to the longitudinal axis of the pedestal, wherein the first portion has a length that is less than a length of the second portion along a perimeter of the sidewall, the length of the first portion and the length of the second portion defined perpendicular to the axis of which the recess extends, and wherein the second portion is configured to be positionable over the physiological characteristic sensor to apply a force to the physiological characteristic sensor in a second position in which the physiological characteristic sensor is uncoupled from the pedestal and deployed onto an anatomy.

7 . The pedestal of claim 6 , wherein the at least one post comprises two posts that are spaced apart on the first side, and each of the posts have a plurality of sides to couple the pedestal to the physiological characteristic sensor.

8 . The pedestal of claim 6 , wherein the recess is symmetric about the axis of which the recess extends.

9 . The pedestal of claim 6 , wherein the first portion has a first height along the axis of which the recess extends and the second portion has a second height defined between the first side and the second side of the pedestal along the axis of which the recess extends, and the second height is less than the first height.

10 . The pedestal of claim 6 , wherein the first portion has a first width and the second portion has a second width, and the first width is greater than the second width such that the first portion is recessed into the sidewall, with the first width and the second width defined by the sidewall and perpendicular to the axis of which the recess extends.

11 . The pedestal of claim 6 , wherein the at least one post comprises at least two posts.

12 . The pedestal of claim 11 , wherein the at least two posts are rotated relative to one another.

13 . The pedestal of claim 11 , wherein each of the at least two posts define a plurality of points of contact to form the interference fit with the physiological characteristic sensor in the first position in which the physiological characteristic sensor is coupled to the pedestal, and wherein each of the plurality of points of contact of each of the at least two posts is in contact with a corresponding surface of the physiological characteristic sensor in the first position.

14 . The pedestal of claim 6 , wherein the recess defines at least one first contact surface along the length of the first portion at the second side and at least one second contact surface along the length of the second portion at the second side, and wherein the second portion is configured to be positionable over the physiological characteristic sensor such that the at least one first contact surface and the at least one second contact surface to apply a force to the physiological characteristic sensor in the second position in which the physiological characteristic sensor is uncoupled from the pedestal and deployed onto the anatomy.

15 . A pedestal for a physiological characteristic sensor assembly, the pedestal comprising:
a first side opposite a second side, with a sidewall that interconnects the first side and the second side, and a first end opposite a second end; 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; and a recess defined in the sidewall at the second end, the recess having a first portion in communication with a second portion, the first portion having a first length that is less than a second length of the second portion along a perimeter of the sidewall, the first portion having a first width and the second portion having a second width, the first width greater than the second width, and the second portion being positionable to apply a force to the physiological characteristic sensor.

16 . The pedestal of claim 15 , wherein the at least one post comprises two posts that are spaced apart on the first side, and each of the posts have a plurality of sides to couple the pedestal to the physiological characteristic sensor.

17 . The pedestal of claim 15 , wherein the recess extends along an axis that is substantially perpendicular to a longitudinal axis of the pedestal.

18 . The pedestal of claim 17 , wherein the recess is substantially symmetric about the longitudinal axis.

19 . The pedestal of claim 15 , wherein the at least one post comprises at least two posts.

20 . The pedestal of claim 19 , wherein each of the at least two posts define a plurality of points of contact to form an interference fit with the physiological characteristic sensor in a configuration in which the physiological characteristic sensor is coupled to the pedestal, and wherein each of the plurality of points of contact of each of the at least two posts is in cont
