摘要： The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle and a reservoir. The needle is configured to project from a distal end of the housing. The reservoir is disposed in the housing and has a flexible wall. The medicament delivery device further comprises a dispensing member and a biasing member. The dispensing member is disposed in the housing and the biasing member is configured to bias the dispensing member to move in an arcuate path relative to the housing such that the dispensing member moves across the flexible wall of the reservoir to dispense medicament from the reservoir when the reservoir contains medicament.

摘要： An autoinjector includes a case adapted to hold a medicament container having a needle, a needle shroud telescopically coupled to the case, and a plunger rotationally and slidably disposed in the case. The needle shroud is movable between a first extended position relative to the case in which the needle is covered and a retracted position relative to the case in which the needle is exposed. The plunger is rotatable relative to the case between a first rotational position in which the plunger is engaged to the case and a second rotational position in which the plunger disengages the case. The needle shroud is operably coupled to the plunger. When the needle shroud translates from the first extended position to the retracted position, the plunger rotates from the first rotational position to the second rotational position.

摘要： The invention refers to a medical device for supporting health control. In order to provide safe access to a dose helper functionality, the device has a first storage means arranged to store an initial data matrix with at least one initial parameter set containing at least two initial data entries for one parameter of the dose helper functionality; receiving means arranged to receive initialization data and/or security data, preferably from a second storage means, for example provided by a hardware key; selecting means operable to select based at least in part on the initialization data one data entry for each initial parameter set as initial data or one initial parameter template containing a reference to one data entry for each initial parameter set as initial data; and first activation means arranged to activate, preferably based at least in part on the security data, execution of the dose helper functionality based on the selected initial data. The invention further refers to a respective medical system, a method for providing such information, a respective computer program and a respective computer program product.

摘要： A needle assembly for use with a drug delivery device comprises a cap releasably secured to the drug delivery device and a blocking member. The blocking member comprises a disinfectant swab and a user graspable portion. The blocking member is configured to be physically moved with respect to the needle assembly by a user. The needle assembly is configured such that in an initial position, the blocking member blocks the cap from being removed from the drug delivery device and movement of the blocking member from the initial position causes the disinfectant swab to contact a septum of a cartridge retained within the drug delivery device.

摘要： According to the invention, an auto-injector for administering a dose of a liquid medicament (M) comprises of a substantially cylindrical housing arranged to contain a pre-filled syringe filled with the medicament (M), a needle shroud slibably arranged with respect to the housing and adapted to rest on the skin of a patient receiving an injection, a releasable drive means arranged within the housing that is capable of, upon release, translating the needle shroud in a proximal direction (P) towards a safe position (PS) and a rotating collar rotatably arranged within the housing. The needle shroud in the safe position (PS) surrounds the injection needle after the injection has been carried out. The rotating collar engages the needle shroud in a manner that forces the rotating collar to rotate within the housing when the needle shroud is translated in the proximal direction (P).

摘要： A supplementary device configured to be releasably attached to a drug delivery device. The supplementary device comprises a housing having a channel configured to slidably receive the drug delivery device; a first alignment feature to ensure a specific alignment of the supplementary device relative to the drug delivery device and restrict rotational movement of the supplementary device around a drug delivery device; and a second alignment feature to prevent sliding movement of the supplementary device relative to the delivery device once attached thereto. The second alignment feature comprises a moveable securing member biased towards the drug delivery device, and a release member operable to move the securing member out of engagement with the drug delivery device.
