Abstract
A multi-purpose automatic injector, comprising a base unit having a forward end and a rearward end and arranged along a longitudinal axis; a cartridge containing a medicament, the cartridge being coupled adjacent to the forward end of the base unit; a drive assembly attached to the base unit and configured to be actuated by a computerized controller; at least one piercing element configured to be operatively coupled with the drive assembly and configured to be movable by the drive member relative to the cartridge in a reciprocating manner upon receipt of a corresponding signal from the computerized controller.
Claims20
A multi-purpose automatic injector for use with a syringe containing a first medicament and having a needle attached to one end thereof and a plunger inserted into said syringe at another end thereof and being slidably displaceable with respect thereto, comprising:
- a base unit having a forward end and a rearward end and arranged along a longitudinal axis;
- a cartridge containing a second medicament, said cartridge being coupled adjacent to the forward end of said base unit;
- a drive assembly attached to said base unit and configured to be operatively coupled with said syringe;
- wherein, in a first mode of operation, said drive assembly is configured to displace said syringe with said needle relative to said base unit, such that said needle moves relative to said cartridge in a reciprocating manner;
- and in a second mode of operation, said drive assembly is configured to displace said plunger rod relative to said syringe to effect ejection of fluid therefrom.
A multi-purpose automatic injector, comprising:
- a base unit having a forward end and a rearward end and arranged along a longitudinal axis;
- a cartridge containing a medicament, said cartridge being coupled adjacent to the forward end of said base unit;
- a drive assembly attached to said base unit and configured to be actuated by a computerized controller;
- at least one piercing element configured to be operatively coupled with said drive assembly and configured to be movable by said drive member relative to said cartridge in a reciprocating manner upon receipt of a corresponding signal from said computerized controller.
A method of operating a multi-purpose automatic injector, comprising the steps of:
- providing a base unit having a forward end and a rearward end and arranged along a longitudinal axis;
- a cartridge containing a medicament, said cartridge being coupled adjacent to the forward end of said base unit;
- a drive assembly attached to said base unit and configured to be actuated by a computerized controller;
- utilizing an automated algorithm for providing a suitable signal to said computerized controller for:
- first longitudinally displacing at least one piercing element, which is configured to be operatively coupled with said drive assembly, relative to said cartridge so that said at least one piercing element protrudes to a first length from a forward end of said cartridge;
- and subsequently longitudinally displacing said at least one piercing element relative to said cartridge in an incremental manner, so that during at least one of said subsequent displacements of said at least one piercing element relative to said cartridge, said at least one piercing element protrudes from a forward end of said cartridge to a second length, whereas said second length is greater than said first length.
