Zusammenfassung:An osmotic actuator (110) for a wearable injection device (100) is disclosed, which osmotic actuator comprises a pressure chamber (150) having one or more outlets (152) and containing a draw solution containing dissolved inorganic salt, one or more osmotic membranes (130), and a cavity (140) containing water, and wherein the one or more osmotic membranes (130) form at least a part of one or more internal surfaces of the pressure chamber (150), wherein the water is in contact with at least a part of one or more external surfaces of the one or more osmotic membranes (130), and wherein the dissolved inorganic salt in the draw solution comprises one or more of the following: CaBr2, CaCl2, ZnBr2, ZnCl2, ZnI2 or LiBr. Furthermore, a wearable injection device (100) comprising such an osmotic actuator (110) and the use of such inorganic salts in a draw solution are disclosed.
