Abstract:
An apparatus is disclosed, comprising a detector unit comprising a detector configured to detect an actuation action performable via the detector unit to an actuation button of a medical device to cause the medical device to eject at least a portion of a medicament comprised in the medical device. The detector is configured to detect the actuation action based on a detection of a force and/or a touch applied to the detector unit as part of the actuation action. The apparatus further comprises an electric unit connected to the detector and configured to store and/or provide information related to the detected actuation action. Furthermore, an according method and a computer program for controlling this method are disclosed.
Abstract:
Some aspects of the present disclosure relate to a drive mechanism for a drug delivery device. The drive mechanism includes: a piston rod to operably engage with a piston of a cartridge to displace the piston in a distal direction during a dose dispensing action, at least one actuation member mechanically coupled with the piston rod to induce a distally directed displacement of the piston rod when actuated by a user, a control to ascertain at least one predefined condition of use, and at least one interlock member coupled with the control to mechanically obstruct displacement of the piston rod if the condition of use is not fulfilled.
Abstract:
A peristaltic pump comprises a tube for transporting a material, wherein the tube is arranged linearly along a longitudinal axis. The peristaltic pump further comprises a pump head for causing a squeezing of the tube, wherein the pump head is rotatable about a rotation axis.

Abstract:
A reservoir assembly comprising a reservoir housing, a piston, and a locking plug, both movably arranged inside the reservoir housing; wherein the volume between the piston and the locking plug defines a reservoir cavity. The reservoir assembly further comprising a reservoir outlet; and an actuator configured to act on the piston; wherein the locking plug is configured to be movable from a first position to a second position; wherein in the first position the reservoir outlet is not in fluid communication with the reservoir cavity. The reservoir assembly further comprising an interlock configured to prevent movement of at least one of the locking plug and the piston; wherein the interlock having a locked position and an unlocked position.
Abstract:
The present invention relates to a method of testing the mechanical integrity of a cartridge (10) containing a medicament and being arranged inside a drug delivery device (20). The invention also relates to a testing arrangement and to a respective drug delivery device, wherein the method comprises the steps of: acoustically stimulating the cartridge (10), measuring of the cartridge's (10) acoustic response (60) to the acoustic stimulation (32), comparing the acoustic response (60) with a standard response (62) of an intact cartridge (10), and determining the mechanical integrity of the cartridge (10) on the basis of the comparison.
Abstract:
The invention relates to a drive mechanism (9) for a needle insertion arrangement (1), the drive mechanism (9) comprising:—an actuator (5),—a needle retainer (7) adapted to retain an injection needle (2) and linearly movable in a distal direction (D) and a proximal direction (P) for moving an injection needle (2),—a cam (17) arranged on or coupled to the needle retainer (7),—a guide curve (16) adapted to be rotated by the actuator (5) about an axis (12) aligned in the distal direction (D) and the proximal direction (P) and adapted to engage the cam (17), wherein the guide curve (16) comprises a sloped section (16.2) such that the needle retainer (7) is moved on rotation of the guide curve (16).
Abstract:
A drive assembly for a medication delivery device is provided, comprising a piston rod which is movable from a start position to an end position for medication delivery and resettable from the end position to the start position. The drive assembly further comprises a guide member, being in engagement with the piston rod, and an impeding element for impeding a movement of the guide member during a reset of the piston rod and thereby impeding the reset of the piston rod. Furthermore, a medication delivery device comprising the drive assembly is disclosed.
Abstract:
The present invention relates to a disposable delivery assembly for a drug delivery device to dispense a liquid medicament, the delivery assembly comprising: a disposable injector comprising an injection needle, a flexible tube and an injector fluid coupling, wherein the injection needle is in fluid communication with the fluid coupling via the flexible tube, a disposable cartridge comprising a reservoir at least partially filled with the liquid medicament and comprising a cartridge fluid coupling in fluid communication with the reservoir, wherein the injector and the cartridge are mechanically interconnected in an undeployed configuration, in which the injector fluid coupling and the cartridge fluid coupling are disconnected, and wherein the cartridge is displaceable relative to the injector into a deployed configuration, in which the injector fluid coupling and the cartridge fluid coupling are in fluid communication.
