AUTO INJECTOR WITH A ROTATABLE RELEASE SHAFT
First Claim
1. An auto injector with a housing for accommodation ofa syringe with a needle, the syringe being movably positioned in the housing between a first position in which position the needle is accommodated inside the housing and a second position in which position the needle protrudes outside the housing,a driver positioned laterally in relation to the syringe and configured for applying a force to the syringe thereby moving the syringe from the first position to the second position,a first injection lock configured in a locked state for preventing syringe movement from the first position to the second position andan injection trigger member configured for releasing the first injection lock to an unlocked state by user operation of the injection trigger member in which unlocked state the first injection lock does not prevent the driver from moving the syringe from the first position to the second position,characterized in that the first injection lock comprisesa rotatable release shaft configured for rotation between a first angular position in which position the shaft prevents movement of the syringe from the first position to the second position and a second angular position in which position the shaft does not prevent movement of the syringe from the first position to the second position.

Abstract
A disposable auto injector (10) having a housing for accommodation of a syringe (18) with a needle movably positioned in the housing between a first position in which the needle is inside the housing and a second position in which the needle protrudes outside the housing, a driver (22) positioned laterally in relation to the syringe and configured for applying a force to the syringe thereby moving the syringe from the first position to the second position, a first injection lock configured in a locked state for preventing syringe movement from the first position to the second position and an injection trigger member (16) configured for releasing the first injection lock to an unlocked state wherein the first injection lock comprises a rotatable release shaft (34) configured for rotation between a first angular position in which it prevents movement of the syringe from the first position to the second position and a second angular position in which position does not prevent movement of the syringe from the first position to the second position.

2. An auto injector with a housing for accommodation of
a syringe with a needle, the syringe being movably positioned in the housing between a first position in which position the needle is accommodated inside the housing and a second position in which position the needle protrudes outside the housing, a driver configured for applying a force to the syringe thereby moving the syringe from the first position to the second position, characterized in that the auto injector further comprises a rotatable release shaft rotatably mounted in the housing between at least three angular positions, for control of the sequence of operation of the auto injector.
