Abstract:
A medicament delivery device (10) for the administration of one or more drug agents is described. The device (10) has a priming mode (920, 945) and a drug delivery mode (947) for administering delivery of the drug agents. The device includes a controller (700) operative for controlling the device (10) to perform a priming operation, and a user interface (74) for activation of the priming operation. The controller (700) is operative to perform the priming operation by way of a plurality of intermittent doses of medicament, the number of intermittent doses being dependent on the activation of the user interface (74).
Abstract:
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.

Wherein, the metered dose inhaler apparatus comprises dose counter means (207) operable in response to the electrical actuation signal to index the dose counter.
Abstract:
A medicament delivery device is shown for the administration of one or more drug agents. The device comprises a medicament cartridge retainer for holding a medicament cartridge. A dispense interface can be attached to an attachment of the device for facilitating fluidic communication from the device. Further, an interface sensor is configured to provide an output indicative of whether the dispense interface is attached to the attachment. The device also comprises a piston rod for driving a bung of the medicament cartridge, and a drive train for advancing the piston rod to the bung. A controller is configured to control the drive train to advance the piston rod towards the bung when the output of the interface sensor indicates that the dispense interface is not on the attachment. The controller is further configured to disable advancement of the piston rod when the output of the interface sensor indicates that the dispense interface is at least partially on the attachment.
Abstract:
Disclosed herein are methods and systems for detecting information related to a drug reservoir (320, 1000, 1002, 1006, 1008). According to one example disclosed herein, a method includes a detector feature (100, 500, 600, 700, 904) determining an electrical property related to a coded material (120, 502, 606, 708, 900) for a drug reservoir (320, 1000, 1002, 1006, 1008), wherein the coded material (120, 502, 606, 708, 900) comprises at least one circuit (122, 400, 800, 802, 804a-e, 902, 906, 908). The at least one circuit (122, 400, 800, 802, 804a-e, 902, 906, 908) may be printed onto the drug reservoir (320, 1000, 1002, 1006, 1008). The method further includes determining information related to the drug reservoir (320, 1000, 1002, 1006, 1008) based at least on the determined electrical property.
Abstract:
A metering valve (1) for a pressurised dispensing container comprising a metering chamber (5); an inlet (9) to the metering chamber and a separate outlet (10) to the metering chamber; one or more sealing members (7, 8) for sealing the inlet (9) to the metering chamber (5) and the outlet (10) to the metering chamber (5). The one or more sealing members (7, 8) are static and the metering chamber (5) is rotatable between a first position, in which the inlet (9) to the metering chamber is open and the outlet (10) to the metering chamber is closed, and a second position, in which the inlet (9) to the metering chamber is closed and the outlet (10) to the metering chamber is open.
Abstract:
Many of those having diabetes take a combination of slow and fast acting types of insulin. It is important that different forms of medicament do not become confused and that the patient does not receive an incorrect medicament. In order to meet the appropriate standard, certain dimensional restrictions are placed upon the cartridge. A medicament cartridge (2, 2') that meets the requirements of this standard and permits more ready discrimination between medicament cartridges having different contents is provided. The medicament cartridge (2, 2') of the present invention is provided with an electrical element (12) having specified electrical properties located on an external face of a displaceable plunger (6, 6').
Abstract:
A medicament delivery device is presented for the administration of one or more drug agents, wherein the device comprises a retainer for holding a medicament cartridge. The retainer is moveable between an open and closed position. A position sensor for generating a position output is indicative of whether the retainer is in the open or closed position. Further, a cartridge sensor generates a cartridge output indicative of whether the retainer is holding a medicament cartridge. A controller controls a predetermined operation of the device in dependence on the output of the position sensor and on the output of the cartridge sensor.
Abstract:
A method (900, 1000) and system (100, 700) for detecting information related to a drug reservoir (400, 800). The method (900, 1000) includes transmitting energy (103) at a coded material (120) disposed on a drug reservoir (400, 800), where the energy (103) has at least one predefined characteristic. The coded material (120) identifies information related to the drug reservoir (400, 800). The coded material (120) modifies the energy (103) and emits the modified energy (105) to a receiver (107, 707). The method (900, 1000) further includes receiving at the receiver (107, 707) the modified energy (105). The method (900, 1000) further includes determining information related to the drug reservoir (400, 800) based on the modified energy (105) as the drug reservoir (400, 800) is loaded into a drug delivery device (600, 1100).
Abstract:
A computerized electro-mechanical drug delivery device (10) configured to deliver at least one dose of two or more medicaments. The device comprises a control unit (300). An electro-mechanical drive unit (500, 600) is operably coupled to the control unit and a primary reservoir (90) for a first medicament and a secondary reservoir (100) for a fluid agent, e.g. a second medicament. An operator interface (60) is in communication with the control unit (300). A single dispense assembly (200) is configured for fluid communication with the primary (90) and the secondary (100) 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 (860), the control unit (300) 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.
