A medicament delivery device is provided having a proximal part and a distal part, the proximal part being arranged to accommodate a medicament container, an information carrier reader arranged to the distal part, provided with at least one antenna, an information carrier arranged to the proximal part, provided with an antenna, an attachment arrangement for attaching the proximal part to the distal part, which attachment arrangement is designed such that said information carrier may assume at least two different positions when the proximal part is attached to the distal part, wherein said at least one antenna of said information carrier reader is arranged such that it is capable of reading information from said information carrier in any of the different positions that the information carrier may assume.

The present invention relates to a medicament injector including an applicator with a cartridge-accepting receptacle. The medicament injector includes interchangeable, pre-filled medicament-containing cartridges. Each cartridge includes at least one barrier member having a closed position in which access to the medicament is inhibited. The barrier member is moveable from the closed position to an open position, in which the medicament is accessible via the applicator, when the cartridge is inserted into the cartridge-accepting receptacle. The barrier member is moves back to the closed position when the cartridge is removed from the cartridge-accepting receptacle. 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.

A drug injecting implement equipped with a sliding attachment unit includes a main body having an accommodating space formed on the inside thereof, and equipped with a handle, an insertion needle having a solution flow pathway for a drug solution to flow therethrough, and of which one side is secured inside the main body while the other side extends outside the main body, an image measuring unit disposed on the main body, and of which one portion is formed in elongated fashion, a sliding attachment unit having an open topped accommodating unit for accommodating a separate drug container on the inside thereof, and which slides selectively on the side surface of the main body and a solution injecting unit provided on the main body and which is adapted such that the drug solution accommodated inside the drug container is injected into the human body via the insertion needle.

Container holder assembly for use in a medicament delivery device, comprising a tubular body elongated in an axial direction, said tubular body having a proximal end and an opposite distal end, and a retaining member releasably arranged to said tubular body for securing an elongated container placed inside the tubular body, wherein said retaining member comprises a resilient structure capable of exerting an axial force on said container in said tubular body for holding the container in a fixed position inside the tubular body and thereby avoiding displacement or breakage of the container and wherein a distal end of said container protrudes from a distal end of said tubular body.

A medicament delivery device is provided having a proximal part and a distal part, the proximal part being arranged to accommodate a medicament container, an information carrier reader arranged to the distal part, provided with at least one antenna, an information carrier arranged to the proximal part, provided with an antenna, an attachment arrangement for attaching the proximal part to the distal part, which attachment arrangement is designed such that said information carrier may assume at least two different positions when the proximal part is attached to the distal part, wherein said at least one antenna of said information carrier reader is arranged such that it is capable of reading information from said information carrier in any of the different positions that the information carrier may assume.

The present invention relates to drug delivery systems that cannot be reloaded or reused and further include a passive safety shield system. The drug delivery devices described herein comprise a drug container comprising at least one bellow, wherein the at least one bellow comprises a first surface and an opposing second surface, wherein the first surface is comprised of a first Belleville spring and the opposing second surface is comprised of a second Belleville spring, wherein the second Belleville spring has a higher spring rate than the first Belleville spring; or a drug container extending between distal and proximal ends, and comprises a continuous change in cross section from proximal end to distal end; a needle, wherein the needle is in liquid communication with the drug container; a plunger extending between a proximal end and a distal end, wherein the plunger is in communication with the drug container and where upon axial movement of the punger, the drug container is compressed; a main body extending between a proximal end and a distal end and comprising an inner body and an outer body, wherein the inner body houses the plunger and the drug container and the outer body is capable of sliding over the inner body and extending past the needle; and a spring located between the inner body and the outer body for urging the outer body to slide over the inner body and extend past the needle.

Embodiments included herein are directed towards a fluid dispensing apparatus. Embodiments may include a housing including a vial containing pre-dosed medication. The apparatus may further include an injection needle contained within a removable needle cap, the injection needle having a drug contact end and a patient contact end, the injection needle configured to puncture at both ends. The apparatus may also include a hinge operatively connecting the housing and the injection needle, wherein the hinge provides movement from a first position wherein the drug contact end is not in contact with the pre-dosed medication to a second position where the drug contact end is in contact with the pre-dosed medication. The apparatus may further include an opening associated with a proximal end of the housing configured to receive the removable needle cap.
