Abstract: A needle mounting system and methods for mounting a needle assembly on a needle mount are disclosed. The needle mounting system includes a needle hub having protrusions extending radially inward. A needle mount has a plurality of slots to receive the protrusions. The slots have a first portion that defines a passageway substantially parallel to a longitudinal axis of the needle mount and a second portion substantially perpendicular to the axis. The needle hub and mount provide a method wherein a needle assembly may be mounted on an injection device without completely rotating the needle hub relative to the needle mount.

Abstract: A cartridge for holding a liquid and for use in a medical delivery device has an elongate barrel provided with a central axis and having a first opening at a first end thereof and a second opening at a second end thereof. The first opening is sealed off by a first sealing means provided with a puncturing area to be punctured by a conduit, such as a hollow needle, and the second opening is sealed off by a stopper that is in intimate contact with a general inner surface of the barrel and is movable within the barrel towards the first sealing means. The puncturing area of the first sealing means is located radially outside the general inner surface of the barrel.

Abstract: A drug delivery device comprising a housing (1) with a drug container (2) being provided with delivering means comprising a piston (5) for expelling a drug (4) from the drug container (2). The housing (1) further comprising a displaceable piston rod (6) abutting the piston (5) of the drug container (2) and rotating means being in engagement with the piston rod (6), said rotating means being provided with a one-way mechanism. The one-way mechanism comprises a helical spring (12) wound tightly around an axle (11), one end of said helical spring (12) being fixed in relation to the housing (1), the other end of the helical spring (12) being in a free state.

Abstract: The present invention relates to a medication delivery device comprising a cartridge assembly, a dosing assembly and optionally a needle assembly. The cartridge assembly comprises a cartridge having a stopper adapted to receive a plunger. Furthermore, the cartridge assembly has one end sealed with a pierce able sealing, said end comprising coupling device for engaging a needle assembly, and another end comprising coupling device for engaging the dosing assembly. The dosing assembly comprises a plunger and has coupling device for engaging the cartridge assembly. The cartridge assembly and the dosing assembly are coupled together for delivering selected doses of medication. The device further comprises mechanism for securing that the plunger abuts on the stopper during use of the device, in particular when the dosing assembly is releasable coupled to the cartridge assembly.

Abstract: By a cylinder ampoule (1), comprising a tubular vessel with a membrane (4) sealingly closing one end and a piston (9) closing the other end, liquid stored between said piston (9) and said membrane (4) can be pressed out through an injection needle (7) piercing the membrane (4) when the piston (9) is pressed into the ampoule (1). The tube is made from a plastically deformable material. A pressure foot (10) on which a piston rod (13) is acting abuts the piston (9), carries a spring plate (11) made from a harder material than is the ampoule (1), is mainly perpendicular to the ampoule (1) axis, and has at least one diameter which is larger than the inner diameter of the ampoule (1) so that edges of the plate (11) abutting the inner wall of the ampoule (1) are deflected away from the piston (9) to form an acute angle with said wall.

Abstract: The invention relates to an automatic injection device, which automatically injects a pre-measured quantity of fluid medicine when a tension spring is released. The tension spring moves the ampoule and the injection needle from a storage position to a deployed position when it is released; the content of the ampoule is thereafter expelled by the tension spring forcing a piston forward inside the ampoule. After the fluid medicine has been injected, torsion stored in the tension spring is released and the injection needle is automatically retracted back to its original storage position.

Abstract: A syringe having a dose setting mechanism, a button which can be operated to inject a set dose, a switch operated at a time between the start and completion of injection, and an electronic presentation of parameters such as the size of a set dose and the size of the last dose administered. The syringe also has a stop watch which is reset and started responsive to operation of the switch. The electronic presentation includes an indication of the number of hours elapsed from the activation of the switch, and may also include, for a predetermined period initially following the activation of the switch, a presentation of the number of seconds elapsed. The latter presentation can provide a visual indication to the patient of the length of time, after the injection button has been actuated to inject the dose, that the needle should remain inserted in the skin.
