A medicament delivery device comprising: a first component, and a second component arranged concentrically with the first component, wherein the second component is configured to move axially relative to the first component from a first position to a second position, wherein one of the first component and the second component has a radially extending flash, wherein the other one of the first component and the second component has a chamfer aligned with and facing the flash when the second component is in the first position, and wherein one of the chamfer and the flash is configured to contact and subsequently pass the other one of the chamfer and the flash when the second component is moved from the first position towards the second position to thereby facilitate movement of the second component.

An autoinjector having a housing for receiving a product container, a propelling member, a drive for automatically discharging a liquid product, a needle-guard spring for pretensioning a needle-guard sleeve, a grid with a multiplicity of latch elements arranged along the longitudinal direction, and an engagement element which, by engagement in the grid, blocks a discharging movement of the propelling member. A control element of the autoinjector interacts with the engagement element via a control cam such that, when the control element moves in the distal direction by the needle-guard spring, the engagement element is brought into engagement with the grid. Since the force of the needle-guard spring is used for the engagement, the engagement element can be mounted without specific elastic force acting in an engagement direction, and can also be mounted in an articulated manner and/or in a manner limited to pure guidance in the engagement direction.

An injection device for in vivo delivery of an agent includes a tubular body defining a lumen that extends along a central axis that is oriented along a longitudinal direction. A distal end of the lumen is occluded and the tubular body defines at least one side-port extending from the lumen to an outer surface of the tubular body. The at least one side-port is elongated along the outer surface of the tubular body.

A pen needle shield assembly comprising a hub fixed to a needle cannula, and a movable shield surrounding the hub, the movable shield comprising an upper portion having an outer diameter, a lower portion having an outer diameter greater than the outer diameter of the upper portion, and a distal opening, wherein the movable shield moves from a first position where the needle cannula is retracted in the movable shield prior to use, to a second position where the needle cannula is extended out of the movable shield through the distal opening for medication delivery and to a third position where the needle cannula is retracted in the movable shield and locked to prevent further use.

The present invention relates to a medicament injector including an applicator with a cartridge-accepting receptacle, and interchangeable, pre-filled medicament-containing cartridges. Each cartridge includes a barrier member having a closed position in which access to the medicament is inhibited. The barrier member is movable from the closed position to an open position, in which the medicament is accessible via the applicator for administration, when the cartridge is inserted into the receptacle. The barrier member is moves back to the closed position when the cartridge is automatically removed from the receptacle once the medication is delivered. This allows for plurality of pre-filled medicament cartridges to be selected on demand via a need-based scenario for quick assembly with the medicament injector for use in various clinical scenarios to reduce the bulk, errors, complexity, and steps in medicament delivery while increasing the versatility, safety, and speed of medicament delivery in time critical situations.

Disclosed is a device for the parenteral delivery of a medication, such as a drug. The device includes upper and lower housings in which the upper housing is configured to move relative to the lower housing as a result of application of an external force to permit the user of the device to control the rate at which the drug is administered.

Described is a medicament delivery device (1), comprising a body (2), a container carrier (7) for retaining a medicament container within the body (2) and being slidably disposed in the body (2), a sleeve (6) slidably coupled to body (2), and a piston rod (11) coupled to the body (2) and the container carrier (7). The piston rod (11) and the container carrier (7) provide a feedback as 10 the container carrier (7) moves from a first position (P1) to a second position (P2) relative to the body (2).

A drug delivery device configured to provide a dose of medicament is disclosed. The drug delivery device includes a main housing, a syringe arranged in the main housing, and a pneumatic power pack arranged in the main housing. The pneumatic power pack includes a pressurized gas source storing pressurized gas, a valve for the pressurized gas source, a sleeve having an inner wall, and a plunger. The sleeve is configured to receive pressurized gas released from the pressurized gas source. The plunger is in sliding gas-tight engagement with the inner wall of the sleeve. Upon activation of the valve, the valve releases the pressurized gas, and the released pressurized gas flows into the sleeve and propels the plunger in a distal direction with respect to the sleeve and the syringe, so as to eject medicament from the syringe.

AUTO-INJECTOR ASSEMBLY The auto-injector assembly (100) includes a housing (102), a syringe assembly (202) to store a predetermined volume of a drug to be administered, a needle guard (212) to surround the syringe assembly (202) such that a portion of the needle guard (212) is adapted to extend out of the housing (102) in an initial state and to retract into the housing (102) when the portion is pressed on to an injection site, a spring holder (218) to hold a dose delivery spring (216) in a compressed state, locking unit (220) to keep the spring holder (218) in a locked state, and a plunger (222) engaged with the spring holder (218) and adapted to move towards the syringe assembly (202) when the spring holder (218) is unlocked. A position of engagement of the plunger 222) with the spring holder (218) is adapted to change for controlling a travelling distance of the plunger (222) within the housing (102) based on the predetermined volume of the drug in the syringe assembly (202).
