摘要： A dose setting device for a delivery system has a piston rod (6, 9) which successively presses a piston (2) into a cylinder ampoule (1). Doses are set by rotating a second part (9) of the piston rod (6, 9) in relation to a first part (6). The two parts are connected by mating threads so that the total length of the piston rod (6, 9) is increased proportional to the angle of rotation, and a point (18) on the second part is moved away from a stop position fixed in relation to a housing (5) The set dose is delivered when the point (18) is moved back to the stop position. The first part (6) can be axially displaced but not rotated in the housing (5), and the second part (9) can both rotate and be axially displaced. The first part (6) is maintained in abutment with the piston (2) and the second part (9) is coupled to be rotated by a dose setting wheel (20). An injection push button (10) is movable between a projecting position and a pressed home position and has elements (13) acting on the second part (9) to press this part to its stop position.

摘要： In a displacement system for controlled infusion of a liquid from a cartridge comprising a tubular vessel (1), which is at a rear end closed by a piston (3) which may be forced by a piston rod (8) moving into the vessel (1) in the axial direction thereof to press out the liquid through an outlet (2) arranged at a front end of the vessel (1), the piston rod (8) is provided as a flexible incompressible construction which is by a piston rod guide (9) behind the rear end of the cartridge deflected away from the axis of this cartridge, preferably 180.degree.. The piston rod guide (9) has a guiding track comprising a curved part and linear parts at each end of the curved part ensuring that the piston rod is guided along a length (a) in the direction of the axis of the cartridge which length (a) is longer than the distance (b) between the two axes of the piston rod parts projecting from the piston rod guide. The guiding track is further elaborated to the very shape which the curved part of the piston rod will spontaneously adopt when its end portions are kept parallel.

摘要： In a syringe dosing mechanism a threaded spindle (1) and a nut (3) cooperates so that relative rotation thereof moves the nut (3) along the spindle (1). The nut (3) has two intersecting bores (12, 15). The first bore (15) has an inner thread (7) matching the outer thread (2) of the spindle (1) and the second bore (12) is smooth and fits slidingly over the spindle (1). The nut (3) is tiltable between a first and a second position. In the first position the threaded bore (15) is coaxial with the spindle (1) and in the second position the smooth bore (12) is coaxial with the spindle (1). The nut (3) is at a first side hinged to a piston rod (6)so that exertion of a force by the nut (3) on the piston rod (6) in a direction (10) by which an injection is performed will tilt said nut (3) into its first position. A piston withdrawal member acts at a second side of said nut diametrically opposite said first side so that the nut (3) is tilted to its second position when the withdrawal member applies a force (13) to said nut (3).
