Patent number: 9095660Abstract: A disposable double pointed injection needle has a needle hub to which a thin needle cannula is permanently fastened and which needle hub can be mounted on to a syringe comprising a dose setting and injection mechanism and a cartridge containing a liquid medicine to be injected subcutaneously into a human body. The needle hub is provided with a safety shield guided on the needle hub. The safety shield is urged in a direction away from the needle hub by a spring located between the needle hub and the safety shield. After injection the shield is moved away from the needle hub by the spring and locked in an irreversible position where the safety shield covers the needle cannula and prevents accidental needle stick injuries.Type: GrantFiled: October 21, 2011Date of Patent: August 4, 2015Assignee: Novo Nordisk A/SInventors: Carsten Gerner Larsen, Lars Stenholt, Anders Molin, Jorn Rex, Bjorn Gullak Larsen

Patent number: 8747363Abstract: A medical device is provided comprising a transcutaneous device unit and a process unit. The transcutaneous device unit may comprise a transcutaneous device for transporting a fluid through a skin portion of a subject, and a mounting surface adapted for application to the skin of the subject. The process unit may comprise a reservoir adapted to contain a fluid drug, the reservoir comprising an outlet means allowing the transcutaneous device to be arranged in fluid communication with an interior of the reservoir, and an expelling assembly for expelling a fluid drug out of the reservoir and through the skin of the subject via the transcutaneous device. The transcutaneous device unit and the process unit further comprise coupling means allowing the reservoir unit to be secured to the transcutaneous device unit in the situation of use. By this arrangement a two-unit system is provided which can be used in a convenient and cost-effective manner.Type: GrantFiled: September 25, 2012Date of Patent: June 10, 2014Inventors: Ole Christian Nielsen, Jim Radmer, Jan Harald Preuthun, Claude Teisen-Simony, Simon Rorvig, Steffen Hansen, Bjorn Gullak Larsen, Claus Schmidt Moller, Philip Albert Sparholt, Erik Winkel Ethelfeld, Henrik Bengtsson

Patent number: 8557179Abstract: The invention provides a device comprising a sealed interior portion with at least one opening covered by a sterilization barrier formed from a non-porous material allowing a sterilization gas to penetrate but prevents germs from penetrating. The size and configuration of the at least one sterilization barrier formed from a non-porous material are adapted to allow at least 50% of the sterilization gas, that would pass between a sterilization gas-containing exterior and the sealed interior portion when a pressure difference is created there between, to pass through the non-porous material.Type: GrantFiled: October 31, 2008Date of Patent: October 15, 2013Assignee: Novo Nordisk A/SInventors: Bjørn Gullak Larsen, Brian Jensen, Ulla Holm Christensen

Publication number: 20120226235Abstract: The invention provides a fluidic system (100) comprising a permeable membrane (152), in which one side of the permeable membrane is in contact with a fluid, this lowering the partial pressure of a gas on the other side of the membrane being by raising the pressure of vapour from the fluid by diffusion from the fluidic system through the permeable membrane. This will aid in expelling a gas from a fluid assembly as well as reducing the likelihood of gas entering into the fluid assembly.Type: ApplicationFiled: August 12, 2008Publication date: September 6, 2012Applicant: Novo Nordisk A/SInventors: Bjørn Gullak Larsen, Steffen Hansen, Kristian Glejbøl, Jens Peter Jensen

Patent number: 8075522Abstract: A disposable double pointed injection needle has a needle hub to which a thin needle cannula is permanently fasten and which needle hub can be mounted on to a syringe comprising a dose setting and injection mechanism and a cartridge containing a liquid medicine to be injected subcutaneously into a human body. The needle hub is provided with a safety shield guided on the outside surface of the needle hub. The safety shield is urged in a direction away from the needle hub by a spring located between the needle hub and the safety shield. The safety shield has a number of protrusions guided in guiding tracks on the outside surface of the needle hub. The guiding tracks are designed such that the safety shield during injection is moved towards the needle hub, and after injection is moved away from the needle hub by the spring and locked in an irreversible position where the safety shield covers the needle cannula and prevents accidental needle stick injuries.Type: GrantFiled: April 1, 2005Date of Patent: December 13, 2011Assignee: Novo Nordisk A/SInventors: Carsten Gerner Larsen, Lars Stenholt, Anders Molin, Jørn Rex, Bjørn Gullak Larsen

Publication number: 20080188810Abstract: The invention provides a pump assembly comprising a suction pump and a safety valve arranged between the pump inlet and a fluid inlet for the assembly. The safety valve comprises an inlet valve and a moveable control member acting on the safety inlet valve, wherein the control member is operatable between an initial position in which the safety inlet valve is closed, and an activated position in which the safety inlet valve is open, and wherein the control member is moved from the initial to the activated position by means of suction action from the pump. By this arrangement the opening of the safety valve is positively controlled by the suction provided by the pump whereas the safety valve is closed during non-operation of the pump.Type: ApplicationFiled: February 24, 2006Publication date: August 7, 2008Applicant: Novo Nordisk A/SInventors: Bjorn Gullak Larsen, Steffen Hansen, Kristian Glejbol, Peter Moller-Jensen, Tue Toft, Niels Hvid, Preben Larsen
