Abstract
An electronic automatic injection device including a housing configured to receive an injection module containing a material to be injected, an electric motor having a rotary drive output, at least one forward driving spring and a multifunctional electric motor driven drive assembly responsive to the rotary drive output of the electric motor and being operative in a first mode of operation, when the injection module includes a prefilled syringe, to enable the at least one forward driving spring to displace the prefilled syringe in a forward direction and in a second mode of operation, when the injection module includes a needleless cartridge, to eject the injectable liquid from the prefilled syringe through a needle.

3. An electronic automatic injection device comprising:
-
a housing configured to receive a prefilled syringe including a needle and containing a material to be injected; an electric motor having a rotary drive output; at least one forward driving spring; and a multifunctional electric motor driven drive assembly responsive to said rotary drive output of said electric motor and being operative; in an initial mode of operation to enable said at least one forward driving spring to displace said prefilled syringe in a forward direction; and in a subsequent mode of operation to eject said injectable liquid from said prefilled syringe through said needle without employing said at least one forward driving spring. - View Dependent Claims (4, 5, 50, 62, 63, 64, 65)

61. A method for injecting a material comprising:
-
providing an injection device configured to receive an injection module containing a material to be injected and including, at least one forward driving spring and a forward driving spring compression assembly operative in response to insertion of said injection module into said device for automatically compressing said forward driving spring; inserting said injection module into device, thereby automatically compressing said forward driving spring; and without any further manipulation of said injection device, thereafter pressing an injection actuation button, which immediately provides injection of said material.
