The invention relates to a device for the dosed delivery of a fluid, in particular an infusion fluid. Said device comprises a housing (1), which has a fluid chamber and a pressurised medium chamber (3), by means of which the exterior of a flexible wall (4) of the fluid chamber is impinged by a pressurised medium. The aim of the invention is to provide a re-usable infusion pump using simple means. To achieve this, the housing (1) consists of two housing parts (6, 7) that can be detachably interconnected, one housing part containing the pressurised medium chamber (3) and the other holding the fluid-tight infusion bag (2) that is configured as an interchangeable fluid chamber. The housing part (6) containing the pressurised medium chamber (3) is sealed off from the housing part (7) that holds the infusion bag (2) by a membrane (5) and is connected to a pressurised gas source (11).
