Abstract

Claims (41)

1 . An assembly comprising:

an on-body device comprising:

(1) a glucose sensor assembly comprising:

a proximal section comprising a connector support coupled with a proximal portion of a glucose sensor; and

a distal section comprising a distal portion of the glucose sensor configured to be positioned under a skin surface and in contact with a bodily fluid of a subject;

(2) a housing comprising:

a top portion comprising a top exterior surface and an aperture;

a base portion configured to be adhered to the skin surface of the subject by an adhesive patch; and

a first space defined by the top portion and the base portion; and

(3) sensor electronics positioned within the first space, the sensor electronics comprising a processor, a battery, and a printed circuit board,

wherein the base portion of the housing comprises a recess in a bottom exterior surface, the recess comprising a distal-facing opening, wherein the recess defines a second space different from the first space, and wherein the recess is configured to receive the connector support via the distal-facing opening, and

wherein the connector support of the glucose sensor assembly is disposed in the recess of the base portion such that the glucose sensor is electrically coupled with the sensor electronics by the connector support.

2 . The assembly of claim 1 , wherein the housing further comprises a side wall, and wherein the sidewall is located between the top exterior surface of the top portion of the housing and the bottom exterior surface of the base portion of the housing.

3 . The assembly of claim 2 , wherein the sensor electronics further comprise a wireless communications facility.

4 . The assembly of claim 3 , wherein the housing further comprises a plurality of engagement recesses circumferentially disposed thereon.

5 . The assembly of claim 4 , further comprising an applicator comprising a sharp.

6 . The assembly of claim 5 , wherein the connector support of the glucose sensor assembly is disposed in the recess of the base portion such that the glucose sensor is electrically coupled with the sensor electronics by the connector support when the on-body device and the sharp are in a first position entirely within the applicator,

wherein the applicator is configured to advance the on-body device and the sharp from the first position to a second position such that a distal end of the sharp pierces the skin surface of the subject and the base portion of the housing is adhered to the skin surface of the subject, and

wherein the applicator is further configured to retract the sharp from the second position to a retracted position entirely within the applicator.

7 . The assembly of claim 6 , wherein the recess of the base portion is configured to receive the connector support via the distal-facing opening while the sensor electronics are in the first space.

8 . The assembly of claim 7 , wherein the sharp extends through the aperture of the top portion of the housing when the on-body device and the sharp are in the first position.

9 . The assembly of claim 7 , wherein the aperture of the top portion of the housing is a first aperture, wherein the printed circuit board comprises a second aperture, and wherein the sharp extends through the second aperture when the on-body device and the sharp are in the first position.

10 . The assembly of claim 9 , wherein the plurality of engagement recesses is detachably engaged to the applicator when the on-body device and the sharp are in the first position.

11 . The assembly of claim 7 , wherein the connector support is electrically coupled with the sensor electronics via an interface that is external to the first space, and wherein the interface is disposed within the recess of the base portion.

12 . The assembly of claim 7 , wherein the glucose sensor assembly further comprises a bent section between the proximal section and the distal section, wherein the proximal section and the distal section are approximately perpendicular to each other when the on-body device and the sharp are in the first position.

13 . The assembly of claim 7 , wherein each engagement recess of the plurality of engagement recesses is disposed on the side wall of the housing, and wherein each engagement recess of the plurality of engagement recesses comprises a concave portion.

14 . The assembly of claim 7 , wherein the distal-facing opening comprises a polygonal cross-sectional area, and wherein a shape of the connector support of the glucose sensor assembly corresponds with the polygonal cross-sectional area of the distal-facing opening.

15 . The assembly of claim 7 , wherein the side wall of the housing comprises a first portion and a second portion, wherein the first portion of the side wall is substantially orthogonal to the bottom exterior surface of the base portion of the housing, and wherein the second portion of the side wall is non-orthogonal to the top exterior surface of the top portion of the housing.

16 . The assembly of claim 7 , wherein on-body device is configured to communicate data indicative of a glucose level to a receiver unit.

17 . The assembly of claim 7 , wherein the plurality of engagement recesses is detachably engaged to the applicator when the on-body device and the sharp are in the first position.

18 . The assembly of claim 7 , wherein the connector support comprises a planar surface.

19 . The assembly of claim 7 , wherein the on-body device further comprises an elastomeric sealing member disposed within the recess of the base portion.

20 . The assembly of claim 19 , wherein the elastomeric sealing member is in contact with the connector support.

21 . The assembly of claim 7 , wherein the adhesive patch is coupled with the base portion when the on-body device and the sharp are in the first position, and wherein the adhesive patch comprises a window aligned with the distal-facing opening.

22 . The assembly of claim 7 , wherein the sensor electronics comprise a first set of mating features coupled with a second set of mating features of the glucose sensor assembly.

23 . The assembly of claim 7 , wherein the recess of the base portion contains a first set of mating features coupled with a second set of mating features of the glucose sensor assembly.

24 . The assembly of claim 7 , wherein the housing comprises a single integral unit.

25 . The assembly of claim 7 , wherein the top portion and the base portion form a single over-molded unit comprising a thermoplastic material, and wherein the single over-molded unit seals the sensor electronics within the first space.

26 . The assembly of claim 7 , wherein the top portion and the base portion are coupled by a snap-fit mechanism such that the sensor electronics are sealed within the first space.

27 . The assembly of claim 7 , wherein the top portion and the base portion are welded together such that the sensor electronics are sealed within the first space.
