Abstract: A frontloaded injection device that includes a cartridge holder into which a replaceable cartridge containing a fluid is inserted. The cartridge holder includes a closing element such as a pair of claws which are displaceable in a radial direction. The closing element is provided at the front of the injection device and locks the cartridge by gripping at the neck part of the cartridge after the cartridge has been loaded into the cartridge holder from the front of the injection device. The closing element is preferably biased in an outwardly radial direction when the locking element is moved axially out of the cartridge holder.

Abstract: A device for injecting preparations is controlled by a sealed circuit block (10) containing integrated sensors (17, 21, 22, 23 24) which monitors selected parameters. Two pairs of integrated Hall elements (21, 23 and 22, 24) monitors movements relative to a sine formed magnetic field presented along the perimeter of a multipoled magnetized ring (7). The Hall elements in each pair are displaced 180° magnetically relative to each other and the two pairs of Hall elements are displaced 90° magnetically from each other. Each pair is coupled to a differential amplifier (25, 26) to provide a cosine and a sine signal, respectively. The sine signal is divided by the cosine signal to create a tangent signal as an entrance to a table showing the angle of the movement.

Abstract: An injection device for injecting set doses from an ampoule (2) mounted in the device, which doses are set by operation of a dose setting button (7) by which operation elastic torsion rods (14) positioned parallel with the longitudinal axis of the device are twisted. By the dose setting a torque is transmitted from the dose setting button (7) to the rods (14) through gear transmissions comprising a toothing (11) carried by a tubular (8) part coupled to the dose setting button (7) to rotate with this button. The toothing (11) engages pinions (13) fixed to the proximal ends of the torsion rods (14), which are made from a super elastic material, which can stand a deformation larger than 2% without being permanently deformed.

Abstract: An injection needle unit for use on a syringe by patient administrated injections, comprising a hub fitting on the syringe which hub carries a needle having a cross section diameter less than 0,320, the needle being made from a super elastic material defined as a material which can obtain recovered elongation of more than 2% without having permanent deformation in the material. The injection needle can be forced away from its original linear shape and the force by which it seeks to return to this linear shape is used for automatic insertion of the needle.

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: 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.

An outer thread (30) engaging an inner thread (29) in a housing is provided on a part (28) of the piston rod (3) so that rotation of the piston rod (3) will screw this rod and the piston (6) into the ampoule (7). A detent (18) ensures that the piston rod (3) is only rotated in a dose administering direction.

Abstract: A kit for mixing comprises a housing accommodating an ampoule containing a solid and a container containing a solvent which is either pre-pressurized or which may be pressurized when it is desired to mix to the liquid and solid components. A needle unit comprises a first needle, the opposite ends of which pierce rubber membranes closing the ampoule and the container, to establish a transport channel through which pressurized solvent flows from the container to the ampoule. The ampoule is vented through a second needle inserted through the membrane of the ampoule and provided with a micro-filter. In one embodiment, the needle unit is displaceable to cause the ends of the needles to pierce the respective membranes, and locked in place by a spring biased locking mechanism. A branch passage from the needle is connected to a cylinder containing a piston coupled to the locking mechanism. When the ampoule is full, pressure in the branch passage will rise, actuating the piston and releasing the locking mechanism.
