Abstract:
Disclosed is a transfilling device ( 1 ) for transfilling a liquid drug from a cartridge ( 3 ) to a flexible reservoir ( 4 ). The transfilling device ( 1 ) includes a support unit ( 111 ) and a plunger ( 113 ), the support unit ( 111 ) configured to receive the cartridge ( 3 ), the plunger ( 113 ) being insertable into the cartridge ( 3 ), wherein the plunger ( 113 ) is displaceable relative to the support unit ( 111 ) along an advancement direction ( 2 ) between a plunger retracted position, where the plunger ( 113 ) is in a most distal position relative to the support unit ( 111 ), and a plunger advanced position, where the plunger ( 113 ) is in a most proximal position relative to the support unit ( 111 ), wherein the plunger ( 113 ) is configured to push a piston ( 32 ) of the cartridge ( 3 ) from a piston retracted position to a piston advanced position by displacing the plunger ( 113 ). The transfilling device ( 1 ) further includes a transfer cannula ( 12, 12 ′), wherein the transfer cannula ( 12, 12 ′) is configured to penetrate a flexible reservoir septum ( 41 ) with a cannula outlet end ( 122 ) and to penetrate a cartridge septum ( 31 ) with a cannula inlet end ( 121 ) and thereby to fluidly couple the flexible reservoir ( 4 ) with the cartridge ( 3 ). The transfilling device further includes a reservoir locking unit ( 13 ), wherein the reservoir locking unit ( ) is configured to releasably mechanically couple the support unit ( 111 ) to the flexible reservoir ( 4 ) and wherein the coupling of the reservoir locking unit ( 13 ) is designed such that the coupling is released in the plunger advanced position.

Claim (Index 14):
Method for transfilling a liquid drug from a cartridge to a flexible reservoir the method including:\n Providing a transfilling device; Releasable coupling a support unit of the transfilling device to the flexible reservoir by a reservoir locking unit; Receiving the cartridge in the support unit; Fluidly coupling the cartridge to the flexible reservoir by a transfer cannula, the transfer cannula penetrating a flexible reservoir septum with a cannula outlet end and penetrating a cartridge septum with a cannula inlet end; Displacing a plunger relative to the support unit along an advancement direction from a plunger retracted position, where the plunger is in a most distal position relative to the support unit to a plunger advanced position, where the plunger is in a most proximal position relative to the support unit; By displacing the plunger pushing a piston of the cartridge from a piston retracted position to a piston advanced position, thereby transfilling the liquid drug from the cartridge to the flexible reservoir; Releasing the coupling of the support unit to the flexible reservoir
