Patent number: 6997911Abstract: The invention relates to: A medication delivery device and a method of making such a device. The object of the present invention is to provide a handy medication delivery device that may be easily adjusted to the different needs of a given user in different situations and to the different needs of different users, and which is economic from a production point of view. The problem is solved in that it comprises a basis module (1) and one or more replaceable modules (2, 3, 4, 5, 6), each of which is adapted to cooperate mechanically and/or electronically with the basis module to provide a specific function, and the basis module includes resources that are jointly used by the replaceable modules. This has the advantage of providing a rational concept for economically supplying high quality, mass-produced devices capable of being customized to individual users' needs for functionality by avoiding the duplication of key components.Type: GrantFiled: May 29, 2001Date of Patent: February 14, 2006Assignee: Novo Nordisk A/SInventor: Lars Peter Klitmose

Patent number: 6796970Abstract: 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).Type: GrantFiled: June 4, 1998Date of Patent: September 28, 2004Assignee: Novo Nordisk A/SInventors: Lars Peter Klitmose, Henrik Andersen, Preben Broskov Nielsen, John Thrane Hansen
