ABSTRACT:
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.
