A device for administering an injectable product in doses including a casing having a receptacle for a container which contains the product and accommodates a piston such that the piston can advance towards an outlet for delivering a selected product dosage, a dosing member, with which a dosing movement can be performed relative to the casing for selecting the product dosage, a drive unit, which can be coupled to the casing and the dosing member such that the drive unit can be adjusted relative to the casing from a dosing starting position to a dosing end position by the dosing movement of the dosing member, an operating mechanism which causes the drive unit to perform a delivering movement by which the piston is advanced towards the outlet, and a restoring spring, which is secured in a tensioned state and is coupled to the drive unit by a release for causing a restoring movement of the drive unit towards its dosing starting position.

Device for administering an injectable product in doses

An administering device with an osmotic drive for administering an injectable product includes a housing with a first chamber containing a solvent, a second chamber containing a solution and a product chamber for accommodating the product. A semi-permeable membrane is disposed between the first chamber and the second chamber. The second chamber is adjoined by a delivery means for delivering product out of the product chamber. A triggering device for triggering the osmotic drive includes an impermeable separating means between the first chamber and the second chamber. The delivery means is slidable relative to the housing along a longitudinal axis of the housing.

Administering device with an osmotic drive

The present invention is an injection device for injecting a fluid product from a reservoir includes a casing having at least two casing portions. The device also includes a mounting for the reservoir such as an ampoule containing the fluid product to be administered, wherein one casing portion at least partially surrounds the reservoir. An activating element for triggering fluid product administering is provided. The at least one casing portion surrounding the reservoir is movable relative to the other casing portion or parts, such that by moving the movable casing portion, the reservoir and/or an injection needle connected to the same is accessible from the outer side of the casing, in order to be replaced.
