A computerized electro-mechanical drug delivery device configured to deliver at least one dose of two or more medicaments. The device comprises a control unit. An electro-mechanical drive unit is operably coupled to the control unit and a primary reservoir for a first medicament and a secondary reservoir for a fluid agent, e.g. a second medicament. An operator interface is in communication with the control unit. A single dispense assembly is configured for fluid communication with the primary and the secondary reservoir. Activation of the operator panel sets a first dose from the primary reservoir and based on the first dose and a therapeutic dose profile, the control unit is configured to determine a dose or range of the fluid agent. Alternatively, the control unit determines or calculates a dose or range of a third medicament. Further, a dispense interface for use with a drug delivery device is disclosed.

In some examples, a medical dispensing device includes a housing and a trigger. A first engager of the device is configured to move axially as the trigger pivots. As the first engager moves, it engages a rod. A maximum proximal position of the rod is defined by a stop. A spring presses the first engager into the trigger such that either the trigger or the first engager rests against a stop limiting rotation of the trigger. A second engager moves axially as the trigger pivots. At the actuated position the second engager, defined by a stop, the second engager limits proximal movement of the rod. An assembly transfers movement of the trigger to the second engager after the trigger has pivoted a threshold amount. A member of the assembly distally moves the second engager. Until it is at the actuated position, the second engager enables the rod to proximally move.

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.

The present invention relates to a medicament delivery device comprising a housing, an actuation mechanism (40) arranged inside said housing, the actuation mechanism comprising a plunger rod (42) arranged to act on a stopper (18) of a medicament container (16); an actuator (84) arranged slidable and connected to the plunger rod (42) for acting on the stopper (18) when said actuator (84) is operated by displacing it in a longitudinal direction of the actuation mechanism (40); an activator (104) rotatably arranged for activating said actuation mechanism and for setting a dose; said activator (104) comprising a generally tubular activator sleeve (148), said activator sleeve (148) comprises protrusions (150) arranged to interact with ledges (90) on said actuator (84) such that said activator sleeve (148) is rotated when said actuator (84) is operated. The invention is characterised in a first audio generating mechanism comprising audio generating elements (94) and said protrusions (150), which protrusions (150) are arranged to cooperate with said audio generating elements (94) for generating an audible signal after said operation for delivering a dose.

An injection device (100) for injection of a medicament from a pre-filled container (10) having a container body (12) for containing the medicament, a needle (16) disposed at a distal end of the container body (12), a removable needle shield (30) and a stopper (22) for expelling medicament from the container (100), the device comprising a housing (110) for housing the container (10), a plunger (142) for driving the stopper (22) of the container (10) in a distal direction to expel the medicament, and a priming mechanism having an operating member (152) which is movable with respect to the housing (110). The priming mechanism is arranged to release the needle shield (30) from the needle (16) and to move the container body (12) in a proximal direction with respect to the plunger (142) upon movement of the operating member (152) from a first position to a second position during an operating sequence of the device.

A needleless injector is provided. The needleless injector includes a loading lever having a working arm part having a lever shaft, a towing member inserted inside the cylinder housing, a link having one end portion pin-coupled to the working arm part and the other end portion pin-coupled to the towing member, an inner cylinder inserted inside the cylinder housing, a spring inserted into the inner cylinder, an actuating head inserted into the inner cylinder in front of the spring and having a catching protrusion configured to be inserted into the slit, and a trigger means having a stopper head part configured to be able to be inserted into the slit of the inner cylinder and detached from the slit. Accordingly, the needleless injector can achieve a reduction in size and thickness by having a simple structure even with a lever for reloading integrally formed therein.

Disclosed is an auto injector for administering a medicament. The auto injector comprising: a housing; a cartridge receiver configured to receive a cartridge assembly comprising a cartridge and a cartridge code feature, the cartridge containing the medicament; a code sensor configured to read the cartridge code feature; a drive module coupled to move a plunger rod; and a processing unit coupled to the code sensor and the drive module. The processing unit being configured to: receive from the code sensor a code signal indicative of the cartridge code feature; control the drive module to move the plunger rod to a first plunger rod position, the first plunger rod position being based on the code signal; receive a trigger event; control the drive module to move the plunger rod to a second plunger rod position following reception of the trigger event.

Injector devices and methods for using them to deliver medicament into a patient's body, e.g., sub-retinally within an eye, are provided. The injector includes a cartridge including a piston slidably disposed within an interior for delivering medicament within the interior through an outlet, and a driver including a plunger coupled to the piston, a source of pressurized fluid, and an actuator member for opening a flow path at least partially between the source and the plunger to advance the plunger and piston to deliver medicament from the interior. One or more sensors are operatively coupled to the plunger to measure displacement of the plunger, a processor is coupled to the sensor(s) for analyzing sensor signals to measure volume of medicament delivered from the interior, and an output device, e.g., one or more LEDs or speakers, provide outputs related to the volume of medicament delivered.

A device for aseptic delivery of biological material from a vial includes a tubular barrel, a filter assembly, and a dispersion assembly. The dispersion assembly is at least partially disposed within the tubular barrel. The dispersion assembly includes a dispersion element, a piston, and a one-way valve. The dispersion element is in fluid communication with the vial to disperse the biological material from the vial. The piston is disposed at the distal end of the dispersion assembly and is in sealing contact with the tubular barrel. The one-way valve forms a fluid passageway in fluid communication with the dispersion element and the tubular barrel. The one-way valve is configured to allow a flow of the dispersed biological material from the dispersion element, through the fluid passageway, and into the tubular barrel, and to prevent a flow of the dispersed biological material from the tubular barrel into the dispersion assembly.
