Abstract

An injection device for aesthetic medicine, for administering a fluid material beneath the skin of a person by means of a syringe. The injection device includes a motor system with a motor configured to drive a first piston, and at least a syringe cover adapted to be mounted on the motor system and to accommodate a syringe comprising at least a syringe barrel for accommodating the filling material, a syringe needle and a second piston located in the syringe and drivable by the first piston for ejecting a quantity of fluid material out of the syringe. The motor system is cable-free and electrically actuated.

Claims

1. An injection device for aesthetic medicine, for administering a fluid material beneath the skin of a person by means of a syringe, the injection device being configured for cordless manual control and comprising:

an electrically actuated motor system comprising a motor configured to drive a first piston, at least one power source, and a gear box; and

at least one syringe cover adapted to be mounted on the motor system and to accommodate a syringe comprising at least a syringe barrel housing the fluid material, a syringe needle and a second piston located in the syringe and drivable by the first piston for ejecting a quantity of fluid material out of the syringe,

wherein the syringe cover is provided with an activator controlling the motor system and the motor system comprises an electronic command circuit equipped with a front activation control switch adapted to cooperate with the activator of the syringe cover for controlling the motor system depending on a user'"'"'s operation of the syringe cover.

2. The injection device of claim 1, wherein the electronic command circuit of the motor system comprises a rear activation control switch adapted to be operated directly by the user for controlling the motor system.

3. The injection device of claim 1, wherein the electronic command circuit of the motor system comprises means for choosing a location on the syringe cover and/or the motor system for controlling the injection device.

4. The injection device of claim 1, wherein the electronic command circuit of the motor system comprises a control menu with input means for a menu-supported, user-controlled operation of the syringe.

5. The injection device of claim 1, wherein the electronic command circuit of the motor system is configured to automatically recognize the syringe cover amongst the set of syringe covers currently mounted on the motor system and to automatically select adequate parameters of injection.

6. The injection device of claim 1, wherein the motor, the at least one power source and the gear box of the motor system are arranged in the assembled state of the device in a non-linear manner with respect to each other.

7. The injection device of claim 1, wherein the injection device comprises a set of different syringe covers adapted to be mounted on the motor system, each syringe cover of the set of different syringe covers being adapted to house one or more types, sizes, and shapes of syringes, and the set of syringe covers comprising different syringe covers designed such as to allow use of the injection device in combination with different types, sizes, and shapes of syringes, as well as different kinds of injection materials.

8. The injection device of claim 1, wherein the syringe cover is configured to accommodate at least parts of the syringe, the syringe cover having an opening at a distal end allowing for penetration of the syringe needle.

9. The injection device of claim 1, wherein the syringe cover is configured to enable an exchange of a syringe needle of the syringe in an assembled state of the syringe cover with the motor system.

10. The injection device of claim 1, wherein the syringe cover is provided with a distal end configured to prevent an accidental expulsion of a syringe needle.

11. The injection device of claim 1, wherein the syringe cover is provided with locking means.

12. The injection device of claim 11, wherein the locking means comprises locking verification means which are configured to enable an operation of the injection device and an actuation of the motor system only if the syringe cover is correctly mounted on the motor system.

13. The injection device of claim 1, wherein the fluid material comprises a dermal filler.

14. The injection device of claim 1, wherein the fluid material comprises botulinum toxin.

15. The injection device of claim 1, further comprising a rotation locking system for rotationally locking a syringe having a luer lock fitting.

16. The injection device of claim 1, wherein the rotation locking system comprises a distal end of the syringe cover, the distal end of the syringe cover including a pair of locking projections extending radially inward from an inner surface of the distal end of the syringe cover, the locking projections configured to engage a portion of the luer lock fitting, thereby minimizing rotational movement of the luer lock fitting within the syringe cover.

17. The injection device of claim 1, wherein the front control switch is further adapted to control a speed of a motor of the motor system in response to pressure applied to the syringe cover.

18. An injection device for aesthetic medicine, for administering a fluid material beneath the skin of a person by means of a syringe, the injection device being configured for cordless manual control and comprising:

an electrically actuated motor system comprising a motor configured to drive a first piston, at least one power source, and a gear box; and

at least one syringe cover adapted to be mounted on the motor system and to accommodate a syringe comprising at least a syringe barrel housing the fluid material, a syringe needle and a second piston located in the syringe and drivable by the first piston for electing a quantity of fluid material out of the syringe,

wherein the syringe cover is provided with an activator controlling the motor system and the motor system comprises an electronic command circuit equipped with a front control switch and a rear control switch.

19. The injection device of claim 18, wherein the rear control switch is adapted to turn the motor system on and off.

20. The injection device of claim 19, wherein the front control switch is adapted to cooperate with the activator of the syringe cover to control a speed of a motor of the motor system depending on a user'"'"'s operation of the syringe cover.
