An injection endpoint signalling assembly is provided that is adapted and configured for mounting on, and use with, a pre-filled syringe. The injection endpoint assembly is configured to prevent a signalling of an injection endpoint before the plunger of the pre-filled syringe has reached a limit of a permitted extent of a direction of injection travel. The assembly is further configured to enable the signalling of the injection end point when the plunger of the pre-filled syringe has reached the limit of the permitted extent of the direction of injection travel and is prevented from moving in a direction of travel different to the direction of injection travel.

A liquid medicine administration device includes a prefilled syringe and a gasket biasing member assembly. The biasing member assembly includes: a gasket pressing member configured to press a gasket; a flange attachment member attached to the prefilled syringe; a biasing member housed between the pressing member and the flange attachment member; and an operating member including an engagement holding portion. The pressing member includes an engagement portion to be engaged with the flange attachment member. When the engagement holding portion is located at an abutment position, deformation of a deformable portion is inhibited by abutment between the engagement holding portion and an abutment portion of a deformable portion, and engagement between the engagement portion and the attachment member body portion is held.

The invention relates to a drug delivery device comprising: a syringe with a body from which a needle extends and an inner sheath; a piston rod comprising a piston and an actuation head, a support sheath for holding the body. It is envisaged that the support sheath and the actuation head comprise corresponding indicators.

A reduced profile syringe assembly is provided that includes an overall profile that is substantially similar to a profile of a syringe barrel. The syringe assembly includes a plunger rod that is significantly disposed within the syringe barrel when filled for use, with the plunger rod adapted to be retracted from the syringe barrel during dispensing of contents of the syringe barrel.

An injection device includes a syringe barrel for holding medication, a collar positioned on a proximal end of the syringe barrel, a piston assembly including a piston arranged in the syringe barrel, and a rod member extending through the collar to the piston, and a blocking member arranged on the rod member. The piston assembly is movable distally relative to the syringe barrel in a priming stroke. The piston assembly is movable relative to the collar during the priming stroke of the piston assembly such that the blocking member longitudinally abuts the piston assembly and the collar at an end of the priming stroke of the piston assembly.

A medication component mixing system is formed of a first syringe, such as a female syringe, and a second syringe such as a male syringe, wherein the system is configured to mix a female portion and a male portion of the medication. The female syringe and the male syringe mechanically couple to one another in an end-to-end fashion for mixing of the contents of the female and male portions.

This invention relates to a container (1) which is pre-filled or pre-fillable with one or more substances, such as a medical liquid and similar, comprising a squeezable activation compartment (2) intended to contain said one or more substances, a dispensing compartment (3) including a first portion (31) equipped with at least one dispensing member (311, 312, 314) of said one or more substances, and a second portion (32), wherein said second portion (32) of said dispensing compartment (3) and said activation compartment (2) are fluid-dynamically connected, and an activator element (4) arranged inside said container (1).

This invention also relates to a method for dispensing at least one substance by means of a container (1), and to a production method of a container (1).

A drug self-delivery device comprising a body portion containing a drug vial and a needle assembly, where the body portion is slidably engaged to a trigger portion. When engaged by a user pressing the trigger portion against the user's flesh, the needle assembly relative to the drug vial so as to align a needle port with an integral drug delivery port connected to the drug vial thereby allowing fluid flow of medication through the needle. Seals engaged by a penetration spring prevent loss of medication and prevent the need for direct connection between the needle assembly and the drug vial.

A medical syringe barrel and a package thereof can secure a sufficient stroke even for operating a Lure Lock type small capacity syringe, and restrain rattle of the syringe barrel inside the tubular member. A medical syringe barrel includes a tubular barrel section for accommodating an internal-use solution in the interior thereof, a tubular injection nozzle section formed at one end of the barrel section, and a flange section formed at an opening section on the other end of the barrel section to project radially outward. The barrel section includes an intermediate body part having an outer diameter smaller than the outer diameter of the injection nozzle section, and a large outer diameter barrel section having an outer diameter equal to the outer diameter of the injection nozzle section, and the large outer diameter barrel section is formed between the flange section and the intermediate body part.
