  • Patent number: 11376369
    Abstract: A syringe including a barrel, a plunger moveably arranged within said barrel, and a plunger rod for driving said plunger. A first engagement member is arranged at the plunger rod, such that a longitudinal movement of the plunger rod yields a rotational movement of said first engagement member. The first engagement member includes a grooved surface. A second engagement member is arranged at the barrel to engage with said grooved surface of the first engagement member, wherein the first engagement member is arranged to move relative to the second engagement member, such that feedback is given to a user as the plunger rod is moved relative to the barrel for driving said plunger. The first engagement member is arranged at said plunger rod with a predetermined play there between.

  • Patent number: 11376412
    Abstract: A clamping mechanism (30) for clamping a flexible tube comprises two rotatable bobbins (22, 32), each with a tube-engaging surface portion (24) defining boundaries of a free space through which a tube may extend. The shape of the tube-engaging surface portion (24) changes around the bobbin circumference, such that axial rotation of the bobbins (22, 32) reduces the free space and thereby squeezes the tube. This allows the flow through the tube to be altered dependent on the rotation of the bobbins.

  • Patent number: 11154654
    Abstract: A coupling mechanism for a medication delivery device includes a first part axially fixed relative to a housing and rotatable around a longitudinal axis of the first part, the first part having a gearing engagement to a second part arranged along the longitudinal axis, the gearing engagement having a first frictional resistance. The second part axially moveable along the longitudinal axis, and directly or indirectly in a friction fit engagement with the housing, which has a second frictional resistance. The first frictional resistance being below the second frictional resistance such that a rotation of the first part in a first direction axially longitudinally moves the second part away from the first part and a rotation in a second direction, opposite to the first rotation direction, reduces the axial distance between the first and second part and/or axially moves the second part into coupling abutment with the first part.
