Patent number: 8357120Abstract: The present invention relates to an injection device comprising a torsion spring operatively connected to a dose setting member being adapted to set a dose to be ejected from the injection device. A rotatably mounted display member adapted to display the dose to be ejected in accordance with a setting of the dose setting member is also provided. The rotatably mounted display member is adapted to be rotated over an angle corresponding to at least one revolution of the display member. The display member may be implemented as a dose indicator barrel having numerals arranged along a helical path on an outer surface thereof, or alternatively, as a counting device having two or more display wheels having numerals arranged on an outer surface thereof.Type: GrantFiled: October 20, 2005Date of Patent: January 22, 2013Assignee: Novo Nordisk A/SInventors: Claus Schmidt Moller, Tom Hede Markussen, Christian Peter Enggaard

Patent number: 8348905Abstract: A mechanical injection device for injecting apportioned doses of a liquid drug. The injection device comprises a dose setting assembly comprising a cap and a cap receiving part, adapted to abut or engage with the cap when the cap is mounted on the injection device, and an injection assembly. Mounting and/or dismounting of the cap on/from the injection device causes the dose setting assembly to set a dose. Thereby a correct dose of drug is automatically set during a cap on/cap off cycle. Since such a cycle is normally performed between two subsequent injections, the number of steps required to be performed by the user is reduced.Type: GrantFiled: January 23, 2009Date of Patent: January 8, 2013Assignee: Novo Nordisk A/SInventors: Bo Radmer, Kristian Glejbøl, Jonas Torry-Smith, Tom Hede Markussen, Lars Morten Bom, Christian Peter Enggaard, Sara Juana Niemann, Martin Ebro

Publication number: 20110098658Abstract: An injection device (1) for injecting predetermined doses of liquid drug is disclosed. The injection device (1) comprises a dose setting mechanism and an injection mechanism. A torsion spring (12) is connected to the dose setting mechanism and to the injection mechanism in such a manner that energy is stored in the torsion spring (12) during dose setting, and the energy is released during injection, the stored energy being used for causing the set dose to be injected. A first mode defining element (8) and a second mode defining element (9) are angularly movable relative to each other in response to operation of the dose setting mechanism. They are also axially movable relative to each other between a first position in which the dose setting mechanism can be operated to set a dose and a second position in which the injection mechanism can be operated to inject a set dose.Type: ApplicationFiled: February 6, 2009Publication date: April 28, 2011Applicant: Novo Nordisk A/SInventors: Christian Peter Enggaard, Tom Hede Markussen, Freddy Michelsen, Morten Sørensen

Publication number: 20110034902Abstract: An injection device (1) for delivering a predetermined fixed dose of liquid drug, the device (1) comprising a housing (2), a first and second tubular members (7, 10). The first tubular member (7) and the housing are engaged via a first track (8) and a first protruding part (9), and the first and second tubular members (7, 10) are engaged via a second track (11) and a second protruding part (12). The first track (8) comprises a first portion (8a) which the first protruding part (9) travels during setting of the dose, and the second track (11) comprises a first portion (11a) which the second protruding part (12) travels during setting of the predetermined fixed dose. The first 10 portions (8a, 11a) of the first (8) and second (11) tracks are shaped in such a manner that the second tubular member (10) is prevented from rotating during setting 15 of a dose. The second tubular member (10) is rotationally locked to a piston rod (13), and rotation of the piston rod (13) during dose setting is thereby prevented.Type: ApplicationFiled: December 19, 2008Publication date: February 10, 2011Inventor: Tom Hede Markussen

Patent number: 7740618Abstract: A ratchet-free and gear-free one-to-one mechanism for setting a dose in a syringe device comprising a dose setting member adapted to be rotated along a piston rod with a threaded outer surface so as to set a dose to be ejected. During dose setting the piston rod is locked such that rotational movement of the dose setting member does not result in rotational movement of the piston rod. During dose ejection the piston rod and the dose setting member are locked in relation to each other such that translational movement of the dose setting member causes relative rotational and translational movement of the piston rod.Type: GrantFiled: October 13, 2005Date of Patent: June 22, 2010Assignee: Novo Nordisk A/SInventor: Tom Hede Markussen

Publication number: 20090137964Abstract: An injection device (1) with an End-of-Content mechanism. The End-of-Content mechanism comprises a track (91) and a track follower each coupled directly or indirectly to the housing and the dose setting member (20) . When setting a dose, the housing and the dose setting member is rotated relatively to each other thereby also rotating the track-follower in the track a distance corresponding to the size of the set dose. This relative rotation is summarized and stored in the position of the track follower in the track. The housing containing the mechanism is preferably equipped with a transparent (71) area through which a user can inspect the position of the track follower in the track and thereby get a visible warning when the drug reservoir in the injection device is about to be emptied.Type: ApplicationFiled: May 18, 2006Publication date: May 28, 2009Applicant: Novo Nordisk A/SInventors: Christian Peter Enggaard, Tom Hede Markussen, Martin Von Bulow, Claus Schmidt Moeller

Publication number: 20080243087Abstract: A mechanism for preventing setting of a dose, which exceeds the amount of a medicament in a reservoir in an injection device. The device comprises a threaded piston rod, a limiter and a driver. The three elements are arranged such that during dose setting, the limiter is moved towards an end-of-contend position, wherein dose setting is limited. The invention comprises an accumulative and a non-accumulative embodiment. The invention further relates to a mechanism for prevention ejection of a dose exceeding the set dose.Type: ApplicationFiled: July 17, 2006Publication date: October 2, 2008Applicant: Novo Nordisk A/SInventors: Christian Peter Enggaard, Claus Schmidt Moller, Tom Hede Markussen
