20090012479 | Injection Device with an End of Dose Feedback Mechanism - An injection device with a dose delivering mechanism being adapted to provide a non-visual, e.g. audible and/or tactile, feedback signal when a set dose has been at least substantially injected. A first and a second part of the injection device are adapted to perform a relative rotational movement with respect to each other. The relative rotational movement causes at least two parts of the injection device to abut or engage, and this abutment or engagement causes the non-visual feedback signal to be generated. A very distinct and precise feedback is provided as compared to prior art axial solutions because the generation of the feedback signal is initiated by the relative rotational movement. Feedback signal may be generated by a change in a rotational velocity of at least one part, e.g. by changing the pitch of a threaded portion or by engaging a non-rotating part and a rotating part, thereby causing the non-rotating part to start rotating. May alternatively be generated by building up and releasing a tension. The injection device is suitable for injecting insulin. | 01-08-2009 |

20090054851 | DOSE SETTING ELEMENT FOR AN INJECTION DEVICE AND HAVING A DOSE SETTING LIMITING MECHANISM - A dose setting element for an injection device, comprising a first part being adapted to rotate during setting of a dose, and a second part being adapted to engage with the first part.

Keeps track of the total dose set since a cartridge was inserted. When the second part has been rotated a predefined number of times is abuts a stop, thereby preventing further dose setting. Prevents setting of a dose beyond an amount remaining in the cartridge. It is not necessary that part of the limiting mechanism travels a distance corresponding to the total dose due to the two separate parts. This allows the dose setting element and injection device to be small as compared to prior art dose limiting mechanisms. Further, an injection device comprising the dose setting element.

20090062748 | Injection Device Having a Gearing Arrangement - An injection device with a gearing arrangement providing a gearing ratio between axial movement of an injection button and axial movement of a piston rod. The injection device comprises a dose setting member being operable to set a dose by rotating the dose setting member relatively to a housing, about a rotational axis.

Thereby the space which it is necessary to accommodate to the gearing arrangement inside the housing is reduced. This provides the possibility of using this space for other purposes, such as additional electronic components, designing the injection device in a manner which is appropriate for other purposes, e.g. with a relatively flat cross section, or reducing the overall size of the injection device. According to one aspect of the invention, the gearing arrangement comprises at least one gear wheel having a rotational axis which is non-parallel to, e.g. substantially perpendicular to, the rotational axis of the dose setting member. According to another aspect of the invention, the gearing arrangement comprises a driving spindle being provided with a threaded portion having a first pitch, and the piston rod is provided with a threaded portion having a second pitch.

20090254048 | Injection control device with gearing mechanism - An injection control device having a metered/controlled injection rate, that is proportional to the rate of withdrawal/injection—suitable for cosmetic as well as other applications—is described. For an injection mode, after the cannula is advanced into an object, the cannula is withdrawn to create a tract or tunnel within the targeted area.

The automatic metering system incorporates a syringe activating mechanism coupled to a gearing system which is capable of proportioning the deposition (or sucking) rate to the retraction/injection rate of the cannula. Accordingly, more consistent and uniform distribution (or harvesting) of material can be achieved with less cannula passes as well as requiring less dependence on the skills of the practitioner of this device. | 10-08-2009 |
