An assembly for a drug delivery device and an associated drug delivery device are provided. The device has a drug delivery device housing and a medicament contained in the drug delivery device housing. A clutch is established between the dose knob and the dial link to prevent inadvertent proximal axial movement of the lead screw away from the cartridge piston, which can lead to dosing inaccuracies.

A syringe use monitoring device that can attach to a syringe and detect the type of medication being loaded and measure the force applied to the plunger and thus monitor subsequent delivery of medication and delivery pressure as a substance is being injected, and at least one display and/or alarm can indicate normal and/or abnormal conditions so that feedback can be employed during the injection process is provided.

A syringe device for ejecting a dose of a medicament, the syringe device comprising: a dose limiting mechanism arranged to interact with a dose ejecting mechanism to prevent ejection of a dose exceeding a set dose, and a safety mechanism, which is arranged such with respect to the dose ejecting mechanism that, if the dose limiting mechanism fails, the safety mechanism prevents ejection of a dose exceeding the set dose.

A syringe exostructure incudes a main body which removably receives a syringe having a syringe barrel and a syringe plunger. A drive plunger is reciprocatably mounted on the main body, and a plunger bar is slidably received in an axial channel on the drive plunger. The plunger bar is configured to removably couple to the syringe plunger when the syringe is introduced into the main body. A drive pawl assembly is fixed to an upper surface of the drive plunger and transfers forward motion of the drive plunger to the plunger bar as the drive plunger is advanced and disengages from the plunger bar when the drive plunger is retracted. A locking pawl assembly is fixed to the main body and extends through a slot formed in the bottom of the axial channel in the drive plunger. The locking pawl engages the plunger bar and allows the plunger bar to be advanced by the drive plunger as the drive plunger is advanced but prevents the plunger bar from being retracted by the drive plunger as the drive plunger is retracted.

An apparatus has a syringe housing. A plunger has a shaft, wherein the plunger is slidably received within the syringe housing between a first and second position. A Hall sensor is disposed within the shaft and a magnet is fixed proximate the syringe housing.

Method of manufacturing a drug delivery device, comprising the steps of (i) providing a plurality of components which in an assembled state form a processor-controlled drug delivery device, (ii) determining a parameter value for at least one component, (iii) assembling the components to form a drug delivery device, and (iv) storing in the processor memory correction data, the correction data being based on one or more differences between a determined parameter value and a corresponding nominal value.

Disclosed is a method for controlling an auto injector and an auto injector for administering a medicament from a cartridge having a first cartridge end and a second cartridge end and having a cartridge outlet at the first cartridge end, the cartridge comprising a cartridge compartment with a first cartridge subcompartment containing a first medicament component of the medicament and a second cartridge subcompartment containing a second medicament component of the medicament. The auto injector comprises: a housing; a cartridge receiver; a cartridge sensor; a drive module; an orientation sensor; and a processing unit.

Disclosed is an auto injector and a method for administering a medicament. The auto injector comprising: a housing; a cartridge receiver; a drive module coupled to move a plunger rod configured to move a first stopper; a temperature sensor configured to provide a temperature signal indicative of the temperature of the medicament in the cartridge; a processing unit configured to: receive the temperature signal; control the drive module to move the plunger rod from a first plunger rod position to a mix plunger rod position wherein the movement from the first plunger rod position to the mix plunger rod position is based on the temperature signal.

A drive mechanism for an injection device for setting and dispensing of a dose of a medicament includes an inner body fixable inside a housing of the injection device, the inner body including an elongated shaft extending in an axial direction. The elongated shaft includes an outer thread and a blocking structure on an outer circumference. The drive mechanism includes a tubular-shaped display member having an inner thread engaged with the outer thread of the inner body, a dose member axially displaceable between a dose setting position and a dose dispensing position relative to the inner body, and a blocking sleeve axially fixed to the dose member, rotationally fixed to the display member and including at least one blocking element to axially engage with the blocking structure to block an axial displacement of the dose member from the dose setting position towards the dose dispensing position.

A drive and metering apparatus for an injection apparatus for releasing a liquid product, the drive and metering apparatus comprising: a) a housing, b) a dose adjustment member, which is rotatable relative to the housing for adjusting the product dose to be released, c) an actuation member which is displaceable from a non-actuated position, which it assumes while adjusting the product dose to be released, into an actuated position, which it assumes while it releases the product, wherein the displacement of the actuation member into the actuated position triggers a product release and the actuation member comprises an actuation section, which is accessible to a user of the drive and metering apparatus and by means of which the user can displace the actuation member from the non-actuated position into the actuated position, d) wherein the actuation section is arranged distally in relation to the dose adjustment member.
