Abstract: The invention relates to a medical injection device having a polymeric housing or housing parts. The housing comprises a moulded outer housing element and a moulded elongated tubular inner housing element. The elongated tubular inner housing element is formed as one unitary element and carries a pointer and one or more projections in predetermined and correlated positions. The pointer points to indicia on a scale drum and the projections engage the scale drum. The outer housing element is moulded over the elongated tubular inner housing element in a 2K moulding to form one single housing component.

Abstract: A damping arrangement (1) for damping radial vibrations in a rotating shaft (2), the damping arrangement (1) comprising at least one first damping element (3), at least one second damping element (4), and a bearing arrangement (5) operably engaging the first damping element (3) and the second damping element (4). The bearing arrangement (5) comprises a first bearing member (6), a second bearing member (7), and a reference (8). The first bearing member (6) is rotatably mounted on the shaft (2) so that radial movement of the shaft (2) is transferred to the first bearing member (6), and is operably connected to the second bearing member (7) by the first damping element (3) and by a first steering structure (9). The first steering structure (9) allows only reciprocating movement of the first bearing member (6), and the shaft (2), in a first radial direction (D1), and the first damping element (3) dampens the reciprocating movement in the first radial direction (D1) with respect to the second bearing member (7).

Abstract: The invention relates to a medical injection device having polymeric housing. The housing comprises a moulded outer housing element and a moulded ring-shaped unitary element. The ring-shaped unitary element carries a pointer and a thread segment in predetermined and correlated positions. The pointer points to indicia on a scale drum and the thread segments guides the scale drum. The outer housing element is moulded over the unitary element to form one single component.

Abstract: The invention relates to a drive mechanism for a medical injection device in which a piston rod (10) has a threaded outer surface and a not circular cross-section and engages a nut assembly (2, 102, 202) having either an internal thread (41, 141, 241) mating the outer thread (11) of the piston rod (10), or a shape mating the non-circular cross section of the piston rod (10). The nut assembly (2) comprises a first part (30, 130, 230) and a second part (40, 140, 240), which are connected by a hinge allowing the first part (30, 130, 230) and the second part (40, 140, 240) to tilt relatively to each other in a non-axial plane.
