The supplement module for injection devices

Japanese Patent JP6013483

B2

A refill module for use with a plunger assembly and having a housing (30), a syringe subassembly (70), a carrier (120) and at least one latching element (170). The syringe subassembly is shiftable within the housing from a retracted position to an injecting position at which its injection tip projects beyond the housing end. The carrier has a passageway in which a plunger of a plunger assembly is insertable for advancement of a piston (80) of the syringe subassembly. The syringe subassembly is engagable by the carrier to be moved from its injecting position to a point at which the injection tip is retracted within the housing when the carrier shifts from a first axial position to a second axial position. The at least one latching element is shiftable relative to the carrier from a retracted arrangement to a latching arrangement such that a latch surface of the latching element restricts a size of the passageway to prevent plunger withdrawal. The carrier is liftable within the housing to retract the injection tip into the housing when the at least one plunger is retracted and a latch abutment surface of that plunger engages the latch surface. When the carrier reaches the second axial position, the at least one latching element is shiftable to move the latch surface clear of the latch abutment surface to allow withdrawal of the at least one plunger from the passageway without further lifting of the carrier.
