Abstract

An automated insertion assembly includes a first dermal perforation assembly configured to releasably engage a first subdermal device. A first actuation assembly is configured to drive the first dermal perforation assembly into a user'"'"'s skin to a first depth and drive the first subdermal device into the user'"'"'s skin to a second depth. The second depth is greater than the first depth.

Claims

1. An automated insertion system comprising:

a cartridge assembly comprising;

a toothed track;

a toothless groove; and

at least one dermal perforation assembly having an interior passage configured to releasably engage at least a portion of a subdermal device therein; and

an actuation assembly configured to drive the at least one dermal perforation assembly a predetermined distance, the actuation assembly comprising;

a drive gear set comprising an uppermost gear, the drive gear set for engaging the cartridge assembly;

an actuator; and

a torsion spring,

wherein when an uppermost gear of the drive gear set is engaged with the toothed track of the cartridge assembly, the actuator is raised and the torsion spring is wound, and

wherein when the uppermost gear of the drive gear set is seated in the toothless groove the torsion spring has stored energy to drive the at least one dermal perforation assembly the predetermined distance.

2. The automated insertion system of claim 1 wherein the subdermal device is chosen from the group consisting of a cannula assembly and a probe.

3. The automated insertion system of claim 1 wherein the at least one dermal perforation assembly comprising:

a first insertion needle assembly for at least partially encapsulating at least a portion of the subdermal device.

4. The automated insertion system of claim 1 wherein the actuation assembly comprising:

an actuator for providing mechanical energy sufficient to drive the at least one dermal perforation a predetermined distance.

5. The automated insertion system of claim 4 wherein the actuator is a spring-based actuator.

6. The automated insertion system of claim 4 wherein the actuation assembly comprising:

one or more gear assemblies for at least partially coupling the actuator to the at least one dermal perforation assembly.

7. The automated insertion system of claim 4 wherein the actuation assembly comprising:

one or more linkage assemblies for at least partially coupling the actuator to the at least one dermal perforation assembly.

8. The automated insertion system of claim 1 further comprising:

at least two dermal perforation assemblies comprising a first dermal preformation assembly and a second dermal perforation assembly, the at first and second dermal perforation assemblies configured to releasably engage a first subdermal device and a second subdermal device respectively; and

a second actuation assembly configured to drive the second dermal perforation assembly.

9. The automated insertion system of claim 8 wherein the second subdermal device is chosen from the group consisting of a canular assembly and a probe.

10. The automated insertion system of claim 8 wherein the second dermal perforation assembly comprising:

a second insertion needle assembly for at least partially encapsulating at least a portion of the second subdermal device.

11. The automated insertion system of claim 8 wherein the second actuation assembly comprising:

a second actuator for providing mechanical energy sufficient to drive the second dermal perforation assembly a predetermined distance.

12. The automated insertion system of claim 11 wherein the second actuator is a spring-based actuator.

13. The automated insertion system of claim 11 wherein the second actuation assembly comprising:

one or more gear assemblies for at least partially coupling the second actuator to the second dermal perforation assembly.

14. The automated insertion system of claim 11 wherein the second actuation assembly comprising:

one or more linkage assemblies for at least partially coupling the second actuator to the second dermal perforation assembly.

15. The automated insertion system of claim 8 wherein the first actuation assembly and the second actuation assembly are a single actuation assembly.
