A computer-controlled injector, including a housing arranged along a longitudinal axis and configured to receive a cassette assembly, containing a medicament cartridge; the housing includes a cassette assembly receiving volume and a cassette assembly insertion and removal opening communicating with the cassette assembly receiving volume; at least one locking element for locking the cassette assembly with respect to the housing upon axial insertion of the cassette assembly into the housing; and an injection drive mechanism including a computer-controlled motor for driving a piston, forming part of the medicament cartridge, for injecting a medicament, the computer-controlled motor also being operative for operating the at least one locking element for releasing the cassette assembly from the housing.

The present disclosure relates to a method of pairing an electronic data logging device of a drug delivery device with an external electronic device and to a respective drug delivery device. The drug delivery device comprises a housing configured to accommodate the medicament and to receive and/or mechanically engage with the electronic data logging device. The drug delivery device further comprises a first device component and a second device component. The first device component is movable relative to the second device component from a first positional state to a second positional state. The first device component comprises a first outer surface, and the second device component comprises a second outer surface. At least one of the first outer surface and the second outer surface comprises a first code portion of a pairing code for establishing a communication link between the electronic data logging device and an external electronic device.

A Housing for an infusion pump cartridge adapted to enclose a glass vessel having an open proximal end closed by a slidable piston and a distal end provided with a neck is provided. The housing is made of plastic. The proximal end is provided with a pair of bayonet fitting formations integrally formed on the housing and adapted to enable the cartridge to be fastened to an infusion pump and with connection means adapted to be arranged at the distal end of the vessel for connection to an infusion set. The housing consists of a cylindrical base part, which is provided with an inner flange for abutment of the vessel and on which the fitting formations are formed, and a neck part that can be fastened to the base part by means of snap fitting formations for retaining the glass vessel between the base part and the neck part.

An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.

The present invention relates to a drug delivery device (100) comprising a housing (101), a threaded piston rod (102), a rotatable drive tube (103), a drive nut (104) in threaded engagement with the piston rod (102) and being rotationally locked but axially moveable relative to the drive tube (103), and a support member (105) arranged rotationally free on the piston rod (102), the support member (105) being axially locked relative to the housing (101) and arranged to allow the drive tube (103) to move axially. The device further comprises a compression drive spring (106) arranged between the piston rod (102) and the drive tube (103), the compression drive spring (106) being arranged axially between the drive nut (104) and the support member (105).

A method of manufacturing a sensor member comprising the steps of arranging an initial sensor member in a fixed position relative to a material-removing tool, and control the tool to (i) remove material from the carrier alignment portion to thereby create an alignment structure, and (ii) remove material from at least one sensor layer area to thereby create a code segment pattern, each code segment thereby being aligned with the alignment structure.

A pen includes a carpule having a longitudinal axis, a first end with a dispensing opening closable by a closure part, a second end via which at least one stopper can be inserted in the direction of the longitudinal axis, and an interior that is tightly closed by the closure part and the at least one stopper. A pen housing has a central axis, receives the carpule, and has a piston rod that interacts with the at least one stopper and a drive for moving the at least one stopper within the interior of the carpule, wherein the second end of the carpule can be inserted into the housing. The drive element moves the carpule into the housing in the direction of the longitudinal axis, which is arranged coaxially to the central axis of the housing, when the drive is activated; and in the process the piston rod is held in a fixed position with respect to the longitudinal direction of the housing such that the piston rod, which is engaged in the second end of the carpule, moves the at least one stopper within the interior of the carpule in the direction of the first end of the carpule.

Drug delivery device has drive assembly adapted to move a piston rod in a distal direction, the drive assembly comprising a drive spring. A rotatable setting member allows a user to set a dose amount to be expelled, the drive spring being strained during dose setting. User actuated release means is provided for releasing the drive spring to thereby move the piston rod in the distal direction corresponding to the set dose. The setting member can be moved axially between an initial position and a proximal setting position, and between the initial position and a distal expelling position, wherein the setting member cannot be rotated to set a dose when in the initial position, the setting member can be rotated to set a dose when in the proximal position, and a strained drive spring is released when the setting member is moved axially from the initial to the distal position.

An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.

The invention relates to an injection device which includes a handle and a guard which together enclose a movable cartridge which can contain liquid material to be injected, and further enclose a movable injector that includes a needle, the needle being attached to a housing where the housing is attached to the cartridge, the device also including a delivery mechanism whereby the needle is moved from a retracted to an extended position, and independently the volume of the chamber may be adjusted to expel the contents thereof through the needle and into a subject in need thereof. The injection device may be communicatively connected to a control unit so as to provide a dermal injection system.
