  • Patent number: 10159801
    Abstract: Assembly for a drug delivery device and drug delivery device An assembly for a drug delivery device (1) is described comprising an activation member (6A) adapted and arranged to be axially moved in a delivery direction for triggering a dose delivery operation of the assembly, a first interaction member (17) and a second interaction member (18) which are adapted and arranged to mechanically cooperate with one another during a dose delivery operation of the assembly and to be rotated with respect to one another during the dose delivery operation, wherein the assembly is configured such that movement of the activation member (6A) in the delivery direction brings the interaction members (17, 18) into mechanical contact for generating a friction between the interaction members (17, 18), wherein an amount of friction controls a relative rotational speed of the interaction members (17, 18) during a dose delivery operation. Furthermore, a drug delivery device comprising the assembly is described.

  • Patent number: 9962500
    Abstract: The invention faces the technical problem of providing a tight connection between a tube and an dispense interface, while at the same time the biocompatibility of the connection can be improved. The technical problem is solved by an apparatus comprising a tube configured to guide a medium and a dispense interface. The tube comprises a first opening and a second opening, while the dispense interface comprises a recess. The recess has a first opening and a second opening and the tube is at least in part inserted into the recess. The tube is permanently affixed to the dispense interface by a combination of an interference fit and an adhesive, such that the interference fit prevents the adhesive from contaminating the medium.

  • Patent number: 9789258
    Abstract: The present invention is directed at a dose setting mechanism for a drug delivery device, comprising an outer sleeve and an inner sleeve located at least partially within the outer sleeve wherein the outer sleeve is connected to the inner sleeve. To reduce noise excitations of the dose setting mechanism, at least one intermediate element is at least partially located in a clearance between the inner sleeve and the outer sleeve in such way that it reduces the relative movement of the inner sleeve and the outer sleeve along a play between the inner sleeve and the outer sleeve. The invention is further directed to a pen-type injector equipped with a respective dose setting mechanism.
