20090254035 | INJECTION DEVICE COMPRISING SEVERAL COUPLING MECHANISMS - An injection device including a drive unit, a delivery unit, a dosing unit, a trigger for triggering an injection, a first coupling mechanism between the drive unit and the delivery unit, and a second coupling mechanism between the dosing unit and the drive unit, wherein the drive unit is tensioned by a rotation of the dosing unit and when the drive unit is tensioned the first coupling mechanism is disengaged and the second coupling mechanism is engaged, and wherein when an injection is triggered first the first coupling mechanism is engaged and then the second coupling mechanism is disengaged. In some embodiments, the device may include a third coupling mechanism which only releases the delivery unit after the engagement and disengagement which follow a triggering. | 10-08-2009 |
20090254044 | INJECTION DEVICE WITH AN AUTOMATICALLY RESETTABLE DOSE LIMITATION UNIT - An injection device for administering a substance from a replaceable container containing the substance, the device including a dosing unit for setting an amount of the substance to be administered, a delivery element, a dose limitation unit operably coupled to the delivery element, and a spring element, wherein the dose limitation unit prevents the setting of a last dose that exceeds a remaining amount of substance available in the container and wherein, when the product container is replaced, the dose limitation unit is automatically reset to a position corresponding to the amount of product available by the spring element moving the delivery element into an end position. | 10-08-2009 |
20100238038 | SERVICE LIFE TIMER FOR A DEVICE FOR ADMINISTERING A PRODUCT IN DOSES - An injection device including at least one sensor for detecting an operating process of the injection device, an electronic circuit connected to the sensor for establishing the beginning and elapsed time of a service life, based on one or more sensor signals, and an output device connected to the circuit for providing a signal indicating the end of the service life. The invention encompasses a method for determining a service life of an injection device, wherein the beginning of the service life is established by one or more sensors for detecting an operating process of the device, a signal is generated which signals the end of the service life, and at least one of an optical, acoustic or tactile output device is associated with the injection device for providing a signal which indicates the end of the service life. | 09-23-2010 |
20110054412 | DUAL-FUNCTION SPRING - An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder. | 03-03-2011 |
20110077595 | BRAKE FOR INJECTION DEVICES - A brake mechanism for an injection device for generating a braking action on a moving, e.g. rotating, part or component of the injection device. | 03-31-2011 |
20120111186 | DEVICE FOR THE DOSED ADMINISTRATION OF A FLUID PRODUCT, ADAPTED FOR THE REPLACEMENT OF A CONTAINER - A device for administering a fluid product, the device including a first housing part provided with a receiver for the product, a second housing part detachably connectable to the first housing part, a piston rod held such that it can be displaced for the exertion of an emptying movement, an actuatable or releasable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element displaceably connected to the second housing part and coupled to the first housing part such that it is displaced, by a movement of the housing parts in relation to each other when the housing parts are separated into a decoupling position wherein the piston rod is decoupled from the coupling input element. | 05-10-2012 |
20120197213 | INJECTION DEVICE COMPRISING SEVERAL COUPLING MECHANISMS - An injection device including a drive unit, a delivery unit, a dosing unit, a trigger for triggering an injection, a first coupling mechanism between the drive unit and the delivery unit, and a second coupling mechanism between the dosing unit and the drive unit, wherein the drive unit is tensioned by a rotation of the dosing unit and when the drive unit is tensioned the first coupling mechanism is disengaged and the second coupling mechanism is engaged, and wherein when an injection is triggered first the first coupling mechanism is engaged and then the second coupling mechanism is disengaged. In some embodiments, the device may include a third coupling mechanism which only releases the delivery unit after the engagement and disengagement which follow a triggering. | 08-02-2012 |
20120245532 | INJECTION DEVICE COMPRISING A DOSING MECHANISM FOR LIMITING A DOSAGE SETTING - An injection device including a dosage setting element and a first element which is coupled to the dosage setting element and can be rotated relative to another, second element when a dosage is being set and is rotationally fixed relative to the second element when a dosage is being delivered, wherein the first element and the second element are coupled via a coupling member, and a stop abutment, wherein when a dosage is being set, the coupling member performs a movement toward a stop position, wherein the coupling member prevents a dosage from being set when it is in the stop position. | 09-27-2012 |
