摘要:
A drug delivery device having a spring element (216) that provides dispense assistance. The drug delivery device includes a variable dose setting mechanism (202), a fixed dose setting mechanism (104), and a mechanical coupling having a spring element. The variable dose setting mechanism is operably coupled to a first reservoir (6) holding a first medicament (1), and the variable dose setting mechanism comprises a dose setter (208). The fixed dose setting mechanism is operably coupled to a second reservoir (5) holding a second medicament. The mechanical coupling operably couples the variable dose setting mechanism and the fixed dose setting mechanism. Further, the variable dose setting mechanism is configured to set a variable dose of the first medicament upon activation of the dose setter, and the fixed dose setting mechanism is configured to set a fixed dose of the second medicament during variable dose setting. Still further, the spring element is configured to store energy during dose setting and to transfer stored energy to the fixed dose setting mechanism to assist with dispense of the fixed dose. 10/236WO
摘要:
The present invention relates to a dose setting mechanism for a drug delivery device and a method of using same. The mechanism comprises a drug delivery device housing, a dose dial sleeve positioned at least partly in the housing and being rotatable during dose setting and dose delivery, a clutch rotatable during dose setting and non-rotatable during dose delivery, and a clutch nut, that is threadedly engaged with the clutch and is splined to the housing to prevent rotation of the clutch nut.
摘要:
A dose setting mechanism for a drug delivery device. The mechanism may comprise a drug delivery device housing. A dose dial component is positioned in the housing and rotatable during dose setting and dose delivery. A split threaded insert is in threaded engagement with the dose dial component. The insert can transform from a first configuration to a second configuration when the dose dial component is rotated. In one dose setting mechanism arrangement, the first configuration may comprise a first open configuration and the second configuration may comprise a second closed configuration.

A drug delivery device comprising: a motor (530) configured to advance a stopper in a cartridge of medicament, the motor comprising an output shaft; a controller; and a motion detection system (522) configured to provide positional feedback to the controller, wherein the motion detection system comprises an optical encoder (534) and at least one element (528) operatively coupled to the output shaft (531) of the motor and configured to rotate with the output shaft such that the at least one element passes through the optical encoder.
摘要:
Various examples of a drug delivery device and corresponding method for sequentially delivering at least two medicaments via a single dispense interface are provided. In one example, the device includes a variable dose setting mechanism operably connected to a first cartridge containing a first medicament, a fixed dose setting mechanism operably connected to a second cartridge containing a second medicament, a dose setter for setting a user settable dose of the first medicament and a fixed dose of the second medicament, and a connecting feature for detachably connecting the variable dose setting mechanism to the fixed dose setting mechanism. During setting of the fixed dose of the second medicament, the rotationally driven variable dose setting mechanism and the fixed dose setting mechanism are connected via the connecting feature, however, during setting of the user settable dose of the first medicament, the rotationally driven variable dose setting mechanism and the fixed dose setting mechanism are not connected.
摘要:
A drug delivery device having a dose limiting system. The drug delivery device includes a first dose setting mechanism (205) operably coupled to a primary reservoir (212) holding a first medicament (214). The first dose setting mechanism includes a first dose setter (208) and is a variable dose setting mechanism. The device further includes a second dose setting mechanism (204) operably coupled to a secondary reservoir (216) holding a second medicament, and the second dose setting mechanism includes a second dose setter (230). Still further, the device includes a dose limiting system (206). The dose limiting system operably couples the variable dose setting mechanism and the fixed dose setting mechanism. Further, the dose limiting system is configured to limit a settable amount of a dose of the second medicament a user can set using the second dose setter based on an amount of a variable dose that a user sets using the first dose setter.
摘要:
A dispense interface component for use with a drug delivery device is provided. The dispense interface component may include a main body (14), a first piercing portion (1208), a second piercing portion (1212), and a biasing element. The main body is configured for connection to the drug delivery device. The first piercing portion is for piercing a first cartridge (1210) contained within the drug delivery device, and the first piercing portion is connected to the main body. The second piercing portion is for piercing a second cartridge (1214) contained with the drug delivery device, and the second piercing portion is connected to the main body. The at least one biasing element (1216) is operably coupled to the main body, wherein the at least one biasing element is configured to, when the load on the at least one biasing element is less than or equal to a threshold load, bias (i) the first piercing portion away from the first cartridge and (ii) the second piercing portion away from the second cartridge.
摘要:
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.
