Embodiment Construction

[0033] figure 1 An injection device for taking a fluid product according to a first embodiment of the present invention is shown. The injection device comprises a product container 1, an injection needle 2 is connected to the product container 1, and the product container 1 is inserted into an elongated housing 3 of the injection device. A piston 4 is arranged in the product container 1 , wherein said piston is movable towards the outlet comprising the injection needle 2 by means of the dispensing device. The dispensing device comprises several elements which together act as a piston rod 5 and move the piston 4 . At the end of the piston rod 5 opposite to the piston 4 , the piston rod 5 presents a circular facing surface 6 .

[0034] for operation figure 1 The operating means of the dispensing device of the injection device shown is formed as a lever 7 comprising a lever arm 8 and a projection 9 . The fulcrum 10 of the rod 7 is arranged laterally on the injection device, a...

Abstract

An injection device for administering a fluid product including operating means (7) pivotable in a radial direction relative to the device about a fulcrum (10) arranged laterally on the device, wherein the operating means includes a protrusion (9) which co-operates with dispensing means (5) for dispensing the product via a surface oblique with respect to a longitudinal axis of the device, such that the dispensing means may be moved in an axial direction relative to the device by pivoting the operating means. In some embodiments, the device may further include a moveable releasing element for releasing a dose, wherein the releasing element projects through an opening, the dimensions of the opening limiting movement of the releasing element in accordance with a predetermined dose amount.

Description

technical field [0001] The present invention relates to injection devices and methods for administering fluid products. More particularly the present invention relates to an injection device comprising manually operated means for dispensing a fluid product, a remaining quantity indicator and a needle guard. Background technique [0002] Conventional injection devices include injection pens for administering various fluids for medical, pharmaceutical and cosmetic purposes, such as insulin, growth hormone, and the like. Generally, they comprise a housing, to which the injection needle is connected, in which are accommodated various means enabling the administration of the fluid product according to the various needs, and a container for containing the fluid product. In general, devices for dispensing a fluid product from a container have a manually actuatable operating device, with which a mechanism can be triggered which discharges the product from the container. Dosing mea...
