摘要： A medication delivery device is disclosed including a rack-and-pinion plunger drive system. The drive system includes an output drive having a pawled end movably coupled with the ratchet teeth of the plunger, and a pinion drive coupled between the housing, the output drive and an actuator. Actuator is longitudinally movable between dose set and delivery positions. Movement of the actuator causes rotation of the pinion drive along the rack to translate the output drive member with the pawled end that is engaged with the plunger ratchet teeth to distally advance the plunger. The device may include one or more of an end of dose mechanism to limit travel of the actuator, a load brake system to stop travel of the plunger under high input forces, a dose detection system, and a dose selector to vary the amount of dose set.

摘要： A dose setting mechanism is provided that includes a dose knob, a dose selector, a radial projecting rib and a snap element. The radial projecting rib is positioned circumferentially on an inside surface of the dose selector. The snap element includes a protrusion. The protruding rib has a reduced section that allows the protruding rib to move axially relative to the protrusion to initiate dose delivery.

摘要： The present invention relates to a drive mechanism for a drug delivery device, comprising: a piston rod to operably engage with a piston of a cartridge to displace the piston in a distal direction during a dose dispensing action, at least one actuation member mechanically coupled with the piston rod to induce a distally directed displacement of the piston rod when actuated by a user, a control to ascertain at least one predefined condition of use, and at least one interlock member coupled with the control to mechanically obstruct displacement of the piston rod if the condition of use is not fulfilled.

摘要： The fluid delivery pen of the present invention has a reduced dose setting friction mechanism which may produce a sound of higher audibility for each click corresponding to one unit dose set using a dose setting mechanism and also produces a sound of lower audibility than the former for each click when the set dose is reduced using the dose setting mechanism. The fluid delivery pen driving mechanism of the present invention has an indication to an end of dose of fluid in a cartridge.

摘要： Driving and dispensing devices for an injection device are used for administering a liquid product and adjusting a product dose and include a dosage display element with a helical dosage scale; an indication device for indicating a dosage value from the dosage scale; and a dosage element, which can be held by a user and screwed relative to the indication device around a rotational axis (L) and relative to the dispensing member along the rotational axis (L) in order to adjust the dosage to be administered. A bearing element having a thread is in a threaded engagement with a thread of the dosage indication element, and the thread pitch of the thread of the dosage indication element is not the same as the pitch (P1) of the helical scale, and may be greater or smaller than the pitch (P1) of the helical scale.

摘要： A medication injector that has an alert indicator that alerts the user when the medication injector is approaching near the end of its medication supply is disclosed. The alert indicator gives the user an opportunity to make preparations to obtain additional medication for the injector if there is an insufficient amount of medication in the injector to enable the user to dispense the required dosage amount with the next injection. Initially, the alert indicator is not visible to the user, but becomes visible to the user when the injector is near empty.

摘要： A display assembly for a drug delivery device (100) is provided. The display assembly comprises a housing (10) having a proximal end (17), a distal end (16) and a longitudinal axis (x). The display assembly further comprises a display member (120) defining a display member window (122), wherein the display member (120) is rotationally locked to but movable with respect to the housing (10) along the longitudinal axis (x). The display assembly further comprises an indication member (60) comprising indicia (66) and a movable member (110) which is rotationally coupled to the indication member (60). The movable member (110) is further coupled to the display member (120) and rotatable with respect to the housing (10). When the movable member (110) is rotated with respect to the housing (10), the rotating movable member (110) moves the display member (120) axially with respect to the housing (10) to display different indicia (66) through the display member window (122).
