Abstract

In a method for preparing a liquid for a medical procedure by mixing at least two liquid components, batches of liquid are successively prepared for continuous withdrawal for use in the medical procedure. The pro-portioning is done using a continuous measurement method A mixing chamber (7), a system (1) and a device (2) for preparing a liquid for a medical procedure are also disclosed, as well as use of such system (1) and device (2). Further a method and a mixing chamber for proportioning components of a liquid for a medical procedure are disclosed.
