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.

A computerized electro-mechanical drug delivery device configured to deliver at least one dose of two or more medicaments. The device comprises a control unit. An electro-mechanical drive unit is operably coupled to the control unit and a primary reservoir for a first medicament and a secondary reservoir for a fluid agent, e.g. a second medicament. An operator interface is in communication with the control unit. A single dispense assembly is configured for fluid communication with the primary and the secondary reservoir. Activation of the operator panel sets a first dose from the primary reservoir and based on the first dose and a therapeutic dose profile, the control unit is configured to determine a dose or range of the fluid agent. Alternatively, the control unit determines or calculates a dose or range of a third medicament. Further, a dispense interface for use with a drug delivery device is disclosed.

The invention relates to a computer-controlled injector, comprising: a housing configured to receive a medicament cartridge; an injection drive mechanism comprising a computer-controlled motor for driving a piston within said medicament cartridge, for injecting the medicament; a data tag attachable to said medicament cartridge; and an electromagnetic detector disposed within said housing and being connectable to the data tag upon mounting of said medicament cartridge into said housing, said electromagnetic detector permitting data to be read from or written to said data tag. The electromagnetic detector is configured to read or write data irrespectively of a rotational orientation of said medicament cartridge within said computer-controlled injector.

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.

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.

Drug delivery devices are configured to inject a drug over an injection time within an acceptable range calculated based on information pertaining to the drug to be injected. In particular, drug delivery devices are described that allow identification of the drug to be injected, calculation or determination of an acceptable range of injection times for the identified drug, determination of a tailored injection time within the acceptable range of injection times, and setting of a delivery speed of a drive such that the drug is expelled over the tailored injection time.

An injector includes a housing and an activation button assembly movably mounted thereto and translatable from an unactuated position to an actuated position. A cartridge door is configured to receive therein a cartridge containing a substance to be dispensed, and is movably mounted to the injector housing between open and closed positions. A deflectable interference member is mounted within the injector housing and, in a resting position, blocks movement of the activation button assembly from the unactuated to the actuated position thereof. The activation button assembly is configured to activate the injector when in the actuated position, and is movable from the unactuated position to the actuated position solely upon deflection of the interference element out of the resting position thereof. The cartridge door, when in the closed position thereof and having the cartridge received therein, deflects the interference element out of the resting position thereof.

A drug delivery device includes a compartment sized to receive a cartridge. The compartment includes a cartridge bay that opens so that a cartridge may be inserted into the cartridge bay and that closes when the cartridge is received by the compartment. The drug delivery device also includes a housing including an expanding assembly. The expanding assembly includes a driver supported from a distal end by a linear stabilizer that includes a bearing configured to push against the housing. The driver is rotated by a motor. The expanding assembly also includes two mid screws threadedly connected to the driver, a plunger driver threadedly connected to the two mid screws, and an anti-rotational guide that prevents rotation of the plunger driver.

A medicament injection device comprising: a needle holder holding a needle, a pivotable cartridge holder, the pivotable cartridge holder being pivotable from an open state to a closed state, wherein the pivotable cartridge holder is arranged to receive a medicament cartridge in the open state, and wherein the needle holder is axially movable towards the pivotable cartridge holder when the pivotable cartridge holder is in the closed state.

An expansion/compression mechanism of a piston rod assembly is composed of a bush shaft, a first cylindrical piston rod that is screwed with the bush shaft, a second cylindrical piston rod that is screwed with the first piston rod, and a piston rod holding member for housing the bush shaft and these piston rods. Therefore, the piston rods move linearly in multiple stages.
