Automated insertion assembly
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.
1. An automated insertion system comprising:
a cartridge assembly comprising:
a toothed track; 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 having a gear for engaging the toothed track of the cartridge assembly;
an actuator; and
a spring;
wherein movement of the actuation assembly relative to the cartridge assembly while the gear of the drive gear set is engaged with the toothed track of the cartridge assembly causes the spring to store potential energy; and
wherein the spring is configured to convert the potential energy to drive the actuator 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 comprises:
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 cartridge assembly further comprises:
a toothless track;
wherein the gear is configured to be seated in the toothless track after the spring has stored the potential energy.
5. The automated insertion system of claim 1 , wherein the spring is a torsion spring.
6. The automated insertion system of claim 1 , wherein the spring is configured to drive the actuator through the drive gear set.
7. The automated insertion system of claim 1 , wherein the at least one dermal perforation assembly comprises:
a first dermal perforation assembly and a second dermal perforation assembly, the first and second dermal perforation assemblies configured to releasably engage a first subdermal device and a second subdermal device, respectively.
8. The automated insertion system of claim 7 , wherein the second subdermal device is chosen from the group consisting of a cannula assembly and a probe.
9. The automated insertion system of claim 7 , wherein the second dermal perforation assembly comprises:
a second insertion needle assembly for at least partially encapsulating at least a portion of the second subdermal device.
10. The automated insertion system of claim 7 , further comprising:
a second actuation assembly configured to drive the second dermal perforation assembly.
11. The automated insertion system of claim 10 , wherein the second actuation assembly comprises:
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 10 , wherein the first actuation assembly and the second actuation assembly are a single actuation assembly.
14. An automated insertion system comprising:
a cartridge assembly comprising:
a toothed track; and
a first dermal perforation assembly having an interior passage configured to releasably engage at least a portion of a first subdermal device therein;
a second dermal perforation assembly having an interior passage configured to releasably engage at least a portion of a second subdermal device therein; and
an actuation assembly configured to drive the first dermal perforation assembly and the second dermal perforation assembly a predetermined distance, the actuation assembly comprising:
a drive gear set having a gear for engaging the toothed track of the cartridge assembly;
an actuator; and
a spring;
wherein movement of the actuation assembly relative to the cartridge assembly while the gear of the drive gear set is engaged with the toothed track of the cartridge assembly causes the spring to store potential energy; and
wherein the spring is configured to convert the potential energy to drive the actuator to drive the first dermal perforation assembly and the second dermal perforation assembly the predetermined distance.
15. The automated insertion system of claim 14 , wherein the first subdermal device is a cannula assembly.
16. The automated insertion system of claim 14 , wherein the second subdermal device is a probe.
17. The automated insertion system of claim 14 , wherein the first subdermal device is a cannula assembly and the second subdermal device is a probe.
18. The automated insertion system of claim 14 , wherein the spring is a torsion spring.
19. The automated insertion system of claim 14 , wherein the cartridge assembly further comprises:
a toothless track;
wherein the gear is configured to be seated in the toothless track after the spring has stored the potential energy.
20. The automated insertion system of claim 19 , wherein the gear is an uppermost gear of the drive gear set.
