Abstract

Claims (22)

1 . A glucose sensor insertion assembly, comprising:

(1) an applicator assembly comprising a housing, an interior, and a distal end;

(2) a sensor electronics assembly releasably retained within the interior of the applicator assembly, the sensor electronics assembly comprising sensor electronics comprising a processor a wireless communications facility, a battery, and a printed circuit board, wherein the wireless communications facility is configured to communicate data indicative of a glucose level to a receiver unit, the sensor electronics disposed within a housing of the sensor electronics assembly, wherein the sensor electronics are configured to electrically couple with a proximal portion of a glucose sensor; and

(3) a removable cap configured to be threadably engaged with the distal end of the applicator assembly,

wherein the housing of the applicator assembly comprises integrally formed grip features,

wherein an end of the removable cap comprises one or more openings configured for passage of a sterilizing gas,

wherein the one or more openings are covered by a gas-permeable seal, wherein the sterilizing gas is ethylene oxide, wherein the gas-permeable seal is configured to permit the passage of the ethylene oxide, and

wherein the interior of the applicator assembly comprises a sterile environment when the removable cap is threadably engaged with the distal end of the applicator assembly.

2 . The glucose sensor insertion assembly of claim 1 , wherein the gas-permeable seal comprises a sterile barrier material.

3 . The glucose sensor insertion assembly of claim 2 , wherein the gas-permeable seal forms a sterile barrier between an interior of the applicator assembly and an exterior of the glucose sensor insertion assembly.

4 . The glucose sensor insertion assembly of claim 3 , wherein the gas-permeable seal comprises a Tyvek material.

5 . The glucose sensor insertion assembly of claim 1 , further comprising an adhesive patch.

6 . The glucose sensor insertion assembly of claim 5 , wherein the ethylene oxide is compatible with the sensor electronics disposed within the housing of the sensor electronics assembly and the adhesive patch.

7 . The glucose sensor insertion assembly of claim 6 , wherein the removable cap comprises a plurality of threads configured for coupling with a complimentary plurality of threads of the applicator assembly.

8 . The glucose sensor insertion assembly of claim 7 , further comprising the glucose sensor, wherein the glucose sensor comprises a distal portion configured to be positioned under a skin surface and in contact with a bodily fluid of a subject.

9 . The glucose sensor insertion assembly of claim 8 , further comprising a sharp, and wherein at least a distal portion of the sharp is configured to receive the distal portion of the glucose sensor.

10 . The glucose sensor insertion assembly of claim 9 , wherein the sensor electronics assembly is configured to be released from the glucose sensor insertion assembly and applied to the subject.

11 . The glucose sensor insertion assembly of claim 10 , wherein the sensor electronics disposed within the housing of the sensor electronics assembly are configured to be electrically coupled with the proximal portion of the glucose sensor prior to application of the sensor electronics assembly to the subject.

12 . The glucose sensor insertion assembly of claim 11 , wherein the printed circuit board comprises an aperture, and wherein the sharp is configured to extend through the aperture.

13 . The glucose sensor insertion assembly of claim 12 , wherein the at least a distal portion of the sharp is configured to pierce the skin surface and position the distal portion of the glucose sensor under the skin surface and in contact with the bodily fluid of the subject.

14 . The glucose sensor insertion assembly of claim 13 , wherein the sharp is configured to be automatically retracted such that the at least a distal portion of the sharp is retracted from the skin surface to a position entirely within the interior of the applicator.

15 . The glucose sensor insertion assembly of claim 14 , further comprising an elastomeric connector comprising a first section, a second section symmetrical to the first section, and a hinge joining the first section and the second section, and wherein the proximal portion of the glucose sensor is configured to be captured between the first section and the second section when the elastomeric connector is in a folded configuration, and wherein the elastomeric connector is configured to establish electrical connectivity between the glucose sensor and the printed circuit board.
