A cassette for use with an injector has a housing, and a cassette identification arrangement (cassette ID) defining a code containing information about the cassette that is detectable and decipherable by an injector. The cassette may further have a sleeve movably disposed within the housing, for holding a drug container, and a locking arrangement for interlocking the sleeve with the housing. The cassette may further have an aperture in the housing, and a cassette cap for removing a needle shield of the drug container. The cassette may have an anti-bending structure to prevent bending or flexing of the cassette cap. The injector may have a processor for controlling operational parameters of the injector and a detector communicatively coupled with the processor for detecting and communicating the cassette ID to the microprocessor to decipher the code defined therein. Also, a method of injecting a drug into a patient with an injector, wherein the sequence of actions performed by the user are controlled. Still further, a method of treating a patient in need thereof wherein a cassette containing a drug is provided and administered to the patient using an injector.

The invention is related to a manifold comprising at least two valve receptacles, further comprising a fluid groove arrangement comprising at least two fluid grooves, wherein a first fluid groove of the at least two fluid grooves has a starting point near a first valve receptacle of the at least two valve receptacles and an end point near a second valve receptacle of the at least two valve receptacles and wherein a second fluid groove of the at least two fluid grooves has a starting point near a second valve receptacle of the at least two valve receptacles. The invention is further related to an apparatus comprising a manifold of the aforementioned kind and further comprising an inner body of a dispense interface.

A method and system for detecting information related to a drug reservoir. The method includes transmitting energy at a coded material disposed on a drug reservoir, where the energy has at least one predefined characteristic. The coded material identifies information related to the drug reservoir. The coded material modifies the energy and emits the modified energy to a receiver. The method further includes receiving at the receiver the modified energy. The method further includes determining information related to the drug reservoir based on the modified energy as the drug reservoir is loaded into a drug delivery device.

A revolving multi-cartridge syringe device includes a needle and two or three revolving holders, each for receiving a cartridge containing medical fluid to be injected. The holders can be pre-loaded with the cartridges, with a first cartridge placed in a loaded position ready to dispense. After fluid in the first cartridge is injected into a patient, a second holder and cartridge are revolved into the loaded position, without breakdown of the syringe. The process can be repeated with a third cartridge. The engagement of each cartridge with the needle and retraction from the needle are implemented by sliding a sliding actuator in either a first direction or a second, opposite, direction, depending on which action is desired. Thus, injection and reloading of the cartridges can be easily actuated by the user through manipulation of a single slidable actuator, without requiring withdrawing the needle from the mouth area to reload.

A medicament delivery device is shown for the administration of one or more drug agents. The device has a priming mode and a drug delivery mode for administering delivery of the one or more drug agents. The device comprises a controller configured to set the device in a priming mode when one or more predetermined states of the device are identified and to disable the drug delivery mode during said predetermined state(s). When states of the device are different from said predetermined states, the controller can set the device in the drug delivery mode. A priming mode may still be enabled through a user interface.

An auto-injector with an interlock mechanism for defining an operation sequence of the auto-injector in a manner to allow a lateral trigger button to be operated only when a proximal end of the auto-injector is pressed against an injection site.

The invention is related to a dispense interface for a drug delivery device for delivering at least two drug agents, wherein the dispense interface is configured to be coupled to a cartridge holder of the drug delivery device, wherein the cartridge holder is configured to hold at least two cartridges, wherein the dispense interface comprises at least two inlet channels, each comprising a fluid inlet opening, wherein each fluid inlet opening is configured to receive fluid from a respective cartridge of the at least two cartridges when the dispense interface is axially coupled to the cartridge holder, an outlet channel comprising a fluid outlet opening, a valve structure configured to be selectively moved into any one of a plurality of positions, wherein in at least one position the valve structure selectively permits or prevents fluid flow from any of the at least two inlet channels to the outlet channel. The invention is further related to a drug delivery device for delivering at least two drug agents comprising a dispense interface of the aforementioned kind.

The invention is related to a dispense interface (402) for a drug delivery device for delivering at least two drug agents, wherein the dispense interface (402) is configured to be coupled to a cartridge holder of the drug delivery device, wherein the cartridge holder is configured to hold at least two cartridges (416, 418), wherein the dispense interface (402) comprises at least two inlet channels (404, 406), each comprising a fluid inlet opening (408, 412), wherein each fluid inlet opening (408, 412) is configured to receive fluid from a respective cartridge of the at least two cartridges (416, 418) when the dispense interface (402) is axially coupled to the cartridge holder, an outlet channel (424) comprising a fluid outlet opening (426), a valve structure (420) configured to be selectively moved into any one of a plurality of positions, wherein in at least one position the valve structure (420) selectively permits or prevents fluid flow from any of the at least two inlet channels (404, 406) to the outlet channel (424). The invention is further related to a drug delivery device for delivering at least two drug agents comprising a dispense interface (402) of the aforementioned kind.

Described is a needle assembly reuse prevention mechanism comprising a barrier movable between a retracted position and an extended position, a spring coupled to the barrier, a pin formed on the barrier, and a slot receiving the pin. When in the extended position, the barrier substantially covers an opening of a needle assembly storage compartment. The spring forces the barrier in a first direction. The slot has at least one abutment face for abutting the pin and preventing movement of the barrier in the first direction.
