Auto-injector comprising a resettable releasing safety device
First Claim
1. An autoinjector comprising:
- a housing;
a receptacle for an active substance, which receptacle, together with a connected injection needle, is displaceable within the housing by spring force for inserting the injection needle into a patient;
a piston displaceable within the receptacle by spring force for expelling the active substance;
a transfer mechanism for transferring the spring force to at least one of the receptacle and piston;
a holding mechanism for holding the transfer mechanism;
a releasing mechanism for causing the holding mechanism to release the transfer mechanism when the releasing mechanism is moved from a first position into a second position; and
a resetting mechanism for moving the releasing mechanism from the first position into the second position without during the move causing the transfer mechanism to be released.

Abstract
An autoinjector including a housing, a receptacle for an active substance, which receptacle, together with a connected injection needle, is displaceable within the housing by spring force for inserting the injection needle into a patient, a piston displaceable within the receptacle by spring force for expelling the active substance, a transfer mechanism for transferring the spring force to the receptacle and/or to the piston, a holding mechanism for holding the transfer mechanism, a releasing mechanism for causing the holding mechanism to release the transfer mechanism when the releasing mechanism is moved from a first position into a second position, and a resetting mechanism for moving the releasing mechanism from the first position into the second position without during the move causing the transfer mechanism to be released.

- 2. An autoinjector for the automatic injection of an active substance, said autoinjector comprising a receptacle for the active substance, which receptacle, together with a connected injection needle, is displaceable within a housing by spring force for the purpose of inserting the injection needle, a syringe piston, which for the purpose of expelling the active substance is displaceable within the receptacle by spring force, a transfer means that transfer the spring force to at least one of the receptacle and syringe piston, a holding means for holding the transfer means, a releasing means for causing the holding means to release the transfer means when the releasing means are brought from a first position into a second position, and selectively actuable resetting means to bring the releasing means from the first position into the second position without causing the transfer means to be released.
