The pharmaceutical injection device includes a main body case, a cartridge holder, a latching receiver, a driver, and an interface component. The cartridge holder has a holding space and a holder latching component. The holding space is capable of holding a pharmaceutical cartridge. The latching receiver latches or releases the holder latching component according to whether the cartridge holder is closed or open. The driver automatically releases the latching of the latching receiver and the holder latching component. The interface component manually releases the latching of the latching receiver and the holder latching component by moving the latching receiver upon being subjected to external pressure. The driver or the interface component releases latching between the latching receiver and the holder latching component.

An autoinjector apparatus is disclosed which comprises a single-use cassette and an autoinjector. The cassette comprises a housing and a sleeve movably disposed in the housing. A syringe may be disposed in the sleeve and secured therein with a lock cap. The lock cap is affixed to a distal end of the sleeve and contacts the distal end of the syringe. A shield remover extends through an opening in a proximal end of the housing for removing a needle shield which covers a needle of the syringe. A cassette identification arrangement is provided on a surface of the housing to enable the autoinjector to identify the cassette. The autoinjector is provided with a detector for reading the cassette identification arrangement.

The invention relates to an injection device comprising a housing, a needle connection (55) for attaching a needle (61) to a cartridge (7) received in the housing (2), an injection drive mechanism (9), an electronic control system for controlling the injection drive mechanism (9) and a needle sensing feature for detecting the attachment of a needle (61) to the cartridge (7). The needle sensing feature includes a slider (13) comprising a magnetic part and an electromagnetic sensor (203) arranged within the housing (2), such that the magnetic part can move between positions remote from the electromagnetic sensor (203) and a position in the vicinity of the electromagnetic sensor (203), when the slider (13) is in its retracted position, wherein the electromagnetic sensor (203) is caused to generate a signal indicative of a needle (61) being attached to the cartridge (7).

A pen-like syringe system includes: a syringe holder for receiving a syringe having a syringe barrel and a plunger guided for movement in the barrel; and a drive housing connected to the syringe holder. To provide an ergonomic syringe system which allows advantageous operation of the system and guarantees safe and focused injection or drawing of a substance the drive housing includes an electric delivery device operated by an integrated power supply for applying pneumatic pressure or negative pressure to the plunger, with the delivery device connected via a drive channel to the plunger and actuatable by a button arranged on the syringe system; and the pen-like syringe system has a vent duct with a first end, which is connected to the drive channel, and a second end, which is connected to the surroundings via an opening, with the opening closable by pressing the button.

Disclosed is an injection device for injecting of a dose of a medicament that includes a housing having a body and a container part configured to accommodate a medicament container and detachably connectable to the body, a drive mechanism arranged in the body and operable to expel the dose of the medicament from the medicament container, a machine-readable identification on or inside one of the body and the container part, and a detector arrangement operable to detect a mechanical connection between the body and the container part. The machine-readable identification is electrically connected to the detector arrangement, is readable by an electronic module of an add-on device connectable to the injection device and is indicative of the mechanical connection between the body and the container part.

A cassette including: a cartridge holder including a first end, a second end having a holder opening, and a holder columnar space located between the first end and the second end and capable of accommodating a drug cartridge, drug cartridge including: a cylinder including a first end at which an injection needle is insertable/extractable, a second end at which a cylinder opening is located, and a cylinder columnar space located between the first end and the second end; a drug placed in the cylinder columnar space; and a gasket being placed in the cylinder columnar space; a cassette cap capable of opening and closing the holder opening, the cassette cap including a first end having a cap opening that is opposed to the holder opening, a second end having a piston insertion opening, and a cap columnar space located between the first end and the second end.
