An injection device (10) comprises an injection solution receptacle (30) and a plunger (70) at least a portion of which is slidably received in the injection solution receptacle (30), wherein the plunger (70) is displaceable relative to the injection solution receptacle (30) in a distal direction in order to expel an injection solution contained in the injection solution receptacle (30) from the injection solution receptacle (30). A first plunger stop mechanism (140) is adapted to stop a displacement of the plunger (70) relative to the injection solution receptacle (30) in the distal direction at a first dosing position (P1). A second plunger stop mechanism (140) is adapted to stop a displacement of the plunger (70) relative to the injection solution receptacle (30) from the first dosing position (P1) in the distal direction at a second dosing position (P2), wherein the first and the second dosing position (P2) of the plunger (70) are selected in such a manner that the plunger (70), upon being displaced relative to the injection solution receptacle (30) between the first and the second dosing position (P2) is adapted to expel a desired dose of the injection solution contained in the injection solution receptacle (30) from the injection solution receptacle (30).

A syringe barrel includes: a barrel body including a nozzle portion at a distal end thereof; and a cap removably mounted to the nozzle portion and configured to seal a distal end opening of the nozzle portion. The cap includes: an inner cap formed of an elastic material and configured to come in liquid tight contact with the nozzle portion in a mounted state in which the cap is mounted to the nozzle portion, and a cylindrical outer cap formed of a material having a higher hardness than the inner cap and fixed around the inner cap. The inner cap includes: a base portion, and a cylindrical wall extending from the base portion in a proximal direction and surrounding the nozzle portion.

A syringe holder includes: a barrel body that holds a syringe; a holder opening; deformation promoting portions; and radial movement-restricting portions. The radial movement-restricting portions are provided close to the deformation promoting portions. Being brought into contact with first portions, the radial movement-restricting portions restrict the syringe from moving in a radial direction with respect to the barrel body.

Described is a catheter patency maintenance device comprising of a flush syringe, an elongate plunger rod with a stopper slidably positioned within the barrel, a cap, disinfectant and a valve movable between an open position and a closed position. The valve may include a valve stem and/or openings in the valve to permit fluid flow. Methods of using the flush syringe assemblies are also described.

An assembly nest for transporting a tubular sub assembly of a drug delivery device on an automated production line, in which the tubular sub assembly includes a tubular body and a cap that is wider than the tubular body. The assembly nest includes a base against which a sub assembly of a drug delivery device is mountable to orientate said sub assembly in a predetermined position; and locking mechanism having a resilient member to urge the locking mechanism into one of: an unlocked position, in which a sub assembly of a drug delivery device can be mounted to the base; or a locked position, in which the locking mechanism engages a mounted sub assembly to retain it in its predetermined position on the base.

Provided are a syringe assembly and a liquid-medicine administration device configured to suppress a variation in a pressure limit of a seal member. In the syringe assembly, the seal member is pressed and held between a pressing surface of a cap and a sealing surface of a distal nozzle portion of a syringe. The seal member is pressed and held in the axial direction in a pressing space over the whole region of an opposing portion between the pressing surface and the sealing surface, and a gap between the pressing surface and the sealing surface in the pressing space is narrowest on the inner peripheral side.

A lock adapter, a syringe assembly, and a prefilled syringe capable of suppressing variation in position on the tip end side of the lock adapter after being subjected to an autoclave sterilization process. The lock adapter is attached to the periphery of a nozzle portion at the tip end of the prefilled syringe and slidable in an axial direction of the nozzle portion. The lock adapter includes: a cylindrical body portion surrounding the periphery of the nozzle portion; and a claw portion protruding to an inner peripheral side from a base end portion of the cylindrical body portion and configured to determine a tip end position of the lock adapter by being caught in an annular rib extending in a circumferential direction of the nozzle portion, in which the claw portion has a circumferential shape when viewed from the axial direction and is integrally connected in the circumferential direction.

The present invention relates to a delivery device for delivering predetermined amounts of fluid, comprising a body (10), a container (16) filled with fluid to be delivered arranged inside said body, said container comprising an opening for expelling said fluid and a wall (18) movable inside said container (16), a threaded plunger rod (46) arranged movable inside said body (10) in the longitudinal direction and in contact with said movable wail (18), a manually operated push means (14, 60) movable in the longitudinal direction capable of, upon operation, move said plunger rod (46) towards said movable wall (18), thereby expelling fluid, and means for transforming a generally linear movement of said push means (14, 60) to a rotational movement of said plunger rod (46).

A multi-cartridge injector includes a plunger having a main brace and a pair of stems, each of the pair of stems having a coupler, a pair of stoppers coupled to each coupler of the pair of stems, a containment unit having a pair of barrels, and a Y-shaped conduit having a pair of branches and a common shaft, and a passageway that extends through the common shaft and the pair of branches, each of the pair of branches being in communication with an interior of one of the pair of barrels.

A closure assembly for a medical device, preferably in the form of a tamper evident closure, having an outer sleeve including an open end and a closed end. A tip cap includes a flow restrictor disposed within the sleeve in accessible relation by the medical device through the open end. An indicator member is removably connected to the tip cap within the sleeve and a retainer member is connected to an interior of the sleeve in an interruptive, disconnecting relation to the indicator member by a snap-fit connection. The indicator member is captured within said hollow interior upon removal of said tip cap from the sleeve through the open end. An end cap may be attached to the sleeve, to define a closed end thereof, by a snap-fit connection similar to, but distinguishable from, the snap-fit connection between the retainer member and the interior of the sleeve.
