Embodiment Construction

[0061] Figure 1 shows a device for dosing a fluid formulation such as insulin, osteoporosis formulations or growth hormones. The device is constructed as an elongated injection pen. It includes a housing, in which the proximal housing section 2 can be seen. A cover 4 covers the distal housing section. The device is in the initial state, ie before or after the dosage of the formulation to be administered is adjusted. A dosing member 18 for adjusting the dosage of the preparation and a dose display with window 7 can be seen. This window is formed as an opening of the housing section 2 and is covered by a transparent cover, eg a magnifying glass; the window 7 can in principle also simply be an opening through which the dose scale can be read out. The dose regulated by means of the dosing member 18 . In the initial state of Figure 1, the dose display shows a dose of "zero". A disc-shaped steering element 30 constitutes the proximal and distal sides of the device.

Abstract

A medicine administering device comprises a housing (1, 2), a first transporting member (11), a second transporting member (12), which is threaded in the first member, a dosing arrangement with an indicator drum (17), a coupling (20-22) between the second transporting member and the display drum and an activation element (30), with which the second transport element is turned relative to the activation element.

Description

technical field [0001] The present invention relates to a device for administering a fluid preparation (Produkt), which may be a pharmaceutical, diagnostic or cosmetic preparation. The present invention is preferably used for automatic drug delivery, but it is not so limited, and medically trained personnel can also administer the drug through the device. Background technique [0002] During the administration of the active ingredient by persons without medical training, eg by themselves, the drug delivery device used must be simple but also safe to operate. In particular, it must be ensured that in devices of this type that can adjust the dose of the item to be injected, the adjusted dose can be displayed with certainty. In the treatment of diabetes, which is the preferred field of application of the present invention, it is also noted that insulin itself may damage the vision of the person being injected, so the adjusted dose should be particularly clear and should be rea...
