A hollow medical needle is disclosed which includes: a hub part having an inner cavity connectable to a syringe; and a puncture part extending out toward an axial distal-end side of the hub part, by forming, at a distal end of the hub part, a puncture index part that includes a step perpendicular to an axial direction and is visible when abutting against a rubber stopper when the rubber stopper of a vial container is punctured by the puncture part, a position of an insertion terminal end substantially coincident with an outer surface of the rubber stopper is set at a fixed position when the puncture part is punctured into the rubber stopper.

The invention relates to a safety assembly for preventing needle stick injury with a needle having a proximal end fixed to a tip of a medical container and a pointed distal end, the safety assembly having: an attachment ring fixed to the tip of the container and a safety device to cover at least the distal end of the needle, the safety device attached to the attachment ring. The safety assembly has an attachment ring having an inner ring and an outer ring to be snapped onto each other, the inner ring having an inner recess for applying glue between the inner ring and the tip, and the inner ring and outer ring having mutually engaging elements preventing any rotation of the outer ring relative to the inner ring.

An assembly for an injection or infusion device includes i) a cartridge being closed by a septum and the surface of the septum being sterile and covered by a first continuous flexible strip, and ii) a fluid path unit comprising a cartridge holder and a fluid path compartment comprising a needle in an interior, the needle is configured to penetrate the septum of the cartridge through a passage in the fluid path compartment. The passage is closed by a second continuous flexible strip keeping the interior of the fluid path compartment in a sterile condition. The cartridge is inserted into the cartridge holder aligning the septum with the passage and sandwiching both strips between the septum and the fluid path compartment. Both strips may be simultaneously removable from the cartridge and fluid path compartment thereby, establishing a sterile connection between the septum and the interior of the fluid path compartment.

A stopper for use in a cartridge or syringe of a medical device .sub.[SL6]is configured to be disposed within a container closure system. The stopper comprises a shell comprising a closed end and an open end with sidewalls extending between the closed end and the open end along a longitudinal axis of the shell. The open end defines a cavity and the sidewalls define an exterior surface sized and shaped to fit inside the container closure system. An insert is configured to be inserted into the cavity, receive a force from a plunger rod, and distribute the force to the shell in order to advance the shell into the container closure system. The closed end of the shell in the cavity defining a convex surface configured to be contacted and deflected by the insert upon insertion into the cavity includes an elastic and/or plastic deformable material.

An auto-injector for hypodermic delivery of medication includes a first subassembly releasably coupled to a second subassembly. The first subassembly includes a cartridge holder configured to receive a medication cartridge, an injection needle through which medication can pass from the medication cartridge, and a needle shield movable between an extended position enclosing the needle and a retracted position in which a proximal end of the needle is not enclosed by the needle shield. The second subassembly includes a movable plunger rod positioned within a housing. Movement of the needle shield in a proximal direction from the retracted position to the extended position following administration of the medication automatically releases the first subassembly from the second subassembly. The released first subassembly is locked with the needle shield in the extended position. A new first subassembly containing an unused dosage of medication may be inserted and releasably connected to the second subassembly.

An injection device configured for attachment to the skin of a patient using an adhesive layer includes a release liner covering the adhesive layer thereby preventing skin attachment. The release liner comprises a sheet of material where a first surface contacts the adhesive layer, and an aperture defining a passage for a film connected to a first sterile barrier film located within the injection device. An end of the film is connected to a second surface of the sheet of material that is opposite to the first surface, and the release liner is covered by a strengthening sheet connected to the second surface and covering the aperture and the end of the film.

An injection device configured for attachment to the skin of a patient includes a housing and a skin adhesive layer attached to an external surface of the housing for attaching the injection device to the skin of a patient. A release liner covering the skin adhesive layer prevents the injection device from attaching to the skin. A film with one end connected to a surface inside of the housing forms a removable sterile barrier and the other end connected to an external surface of the release liner without contacting the skin adhesive layer. The housing, skin adhesive layer and release liner each include a notch defining a passage for the film so that the second end of the film can extend from the interior to the exterior of the housing.

The present disclosure relates to a medicament delivery device comprising: a housing configured to receive a cartridge containing a medicament; an injection needle having a proximal end and a distal end; an injection needle holder to which the injection needle is fixed, the injection needle holder being moveable relative to the housing between a rest position and a use position; and an injection needle cap detachably connected to the injection needle holder and enclosing the proximal end of the injection needle. The medicament delivery device is configured such that pushing the injection needle cap towards the cartridge causes the injection needle holder to move from the rest position in which the distal end of the injection needle is spaced from the cartridge towards the use position in which the distal end of the injection needle can engage the cartridge.

A medicament injection device is provided. The device includes a main body configured to receive a medicament cartridge sealed with a penetrable holder. The device can further include a needle holder holding a needle, a needle sleeve arranged to be axially movable with respect to the main body, and a retainer coupled to the needle holder and to the needle sleeve. The retainer can be axially movable with respect to the main body along the main axis of the device. Upon displacement of the needle sleeve and the retainer by a predefined distance towards a proximal end of the main body, the needle holder and the needle can be displaced axially towards the proximal end of the main body and decouple from the retainer. The needle sleeve can be configured to disengage from the needle holder upon displacement of the needle sleeve.

A cartridge for use with a beneficial agent delivery device having a fillable reservoir. The cartridge includes a reconstitution, unit dose package having first and second compartments, and a fitment. The first compartment contains at least a first constintuent of the beneficial agent. The second compartment contains at least a second constituent of the beneficial agent. The fitment is disposed on the package for interfacing the package to the fillable reservoir.
