Abstract: Drug delivery device with electronically controlled and axially displaceable piston drive member (10) adapted to engage a loaded cartridge piston. The piston drive member is moveable between a proximal loading position in which a cartridge can be received and a distal loaded position in engagement with the piston. A proximity sensor (11,12) provides a varying output indicative of a varying distance between the piston drive member and the piston. A controller (30) coupled to the proximity sensor is configured to control movement of the piston drive member from the loading position to the loaded position and stop movement when the controller based on input from the proximity sensor system determines that the loaded position has just been reached. By this arrangement it is prevented that a drug-filled cartridge is pressurized during the loading and initializing procedure.

Abstract: The present invention provides an apparatus comprising a housing and a flexible reservoir adapted to contain a fluid and having a septum member formed from a needle-penetratable self-sealing material. The flexible reservoir is arranged within the housing in combination with mounting means arranged within or formed by the housing, wherein the mounting means engages the septum member to thereby mount the flexible reservoir relative to the housing. In this way a secure fixation between the reservoir and the housing is provided without having to interfere with the general flexibility of the reservoir, e.g. substantially the entire flexible reservoir apart from the outlet/mounting means may be arranged free to move relative to the housing, this allowing the reservoir to be emptied to a high degree.

Abstract: A microtitration system comprises a plurality of well and a frame-like holder with apertures for receiving the wells. Each well has a bottom wall and a side wall extending upwardly therefrom so as to define an upper open end, and a depression or groove is formed in an outer surface of the well side wall at a position spaced from the bottom wall. Each aperture of the holder is at least partly defined by a resilient aperture defining means, which is adapted to enter into locking engagement with the depression or groove of a well received in the aperture. The dimensions and the shape of each aperture are such that when a well is inserted into the aperture, the aperture defining means is engaging with the outer surface of the well side wall and is pressed radially outwardly in relation to a central axis of the well till the aperture defining means may snap into locking engagement with the depression or groove formed in the side wall of the well.
