Abstract

A modular injection device for administration of dermal filler compositions is provided. The injection device may include a handheld injector unit including a drive unit, the drive unit configured to apply an extrusion force to a fluid; a control unit remote from the injector unit, the control unit configured to control the drive unit; and a cable configured to connect the control unit to the injector unit.

Claims

1. A modular injection system for administration of injectable fluids, the system comprising:

a handheld injector unit including a grippable housing including a distal end having a coupling portion, and a drive unit contained within the housing;

a wrist strap;

a separate portable control unit, remote from the injector unit, the control unit including a controller/processor configured to control the drive unit and configured to be secured to the wrist strap; and

a cartridge, couplable to the coupling portion of the grippable housing, and containing an injectable fluid;

the injector unit including a movable plunger driven by the drive unit and extendable in a distal direction to cause extrusion of the injectable fluid from the cartridge when the cartridge is coupled to the coupling portion.

2. The system of claim 1 wherein the control unit further includes an input device configured to receive user input to program the controller/processor to set an injection rate for the fluid from the cartridge.

3. The system of claim 1 wherein the control unit is removably connectable to the wrist strap.

4. The system of claim 3 wherein the control unit is removably connectable to the wrist strap by magnetic elements.

5. The system of claim 1 further comprising a charging dock configured to receive both the injector unit and the control unit.

6. The system of claim 1 further comprising a cable connecting the control unit to the injector unit.

7. The system of claim 1 wherein the injector unit includes substantially opposing triggers configured to enable ejection of the cartridge from the coupling portion.

8. The system of claim 7 wherein the injector unit housing includes an enlarged distal end defined by substantially opposing, laterally extending flanges and each flange includes one of the substantially opposing triggers.

9. The system of claim 1 wherein the cartridge includes a cartridge ring sealingly engagable with the coupling portion.

10. The system of claim 1 wherein the movable plunger is extendable beyond the distal end of the injector unit housing.

11. The system of claim 1 wherein the control unit is mountable to a user'"'"'s wrist to allow the user to view the control unit while operating the injector unit within the same field of vision.

12. A modular injection system for administration of injectable fluids, the system comprising:

a handheld injector unit including a grippable housing including a distal end having a coupling portion, and a drive unit contained within the housing,

a separate portable control unit, remote from the injector unit, the control unit including a controller/processor configured to control the drive unit;

a cartridge, sealingly couplable to the coupling portion of the grippable housing, and containing an injectable fluid;

the injector unit including a movable plunger driven by the drive unit and extendable in a distal direction beyond the distal end of the grippable housing and into the cartridge to cause extrusion of the injectable fluid from the cartridge when the cartridge is sealingly coupled to the coupling portion;

an input device, on the portable control unit, configured to receive user input to program the controller/processor to cause extrusion of the fluid from the cartridge at a desired injection rate; and

a wrist strap removably connectable to the control unit for enabling the control unit to be coupled to a user'"'"'s wrist during the user'"'"'s operation of the injector unit.

13. The system of claim 12 wherein the control unit is removably connectable to the wrist strap by magnetic elements.

14. The system of claim 12 wherein the injector unit includes substantially opposing triggers configured to enable ejection of the cartridge from the coupling portion.

15. The system of claim 14 wherein the injector unit housing includes an enlarged distal end defined by substantially opposing, laterally extending flanges and each flange includes one of the substantially opposing triggers.

16. The system of claim 12 wherein the control unit when mounted to a user'"'"'s wrist, allows the user to view within the same field of vision the control unit and operation of the injector unit.
