This invention relates to a method for sterilizing a medical unit comprising at least two connections for insertion into a fluid flow of a medical unit where a sterilizing medium flows through the unit. Medical units of this type are e.g. medical filters, in particular dialyzers. A high degree of sterility is here required. This is accomplished through the following steps: a. inserting the unit into a system under pressure- tight coupling of the two connections to a feed conduit and discharge conduit of the system under atmospheric conditions; b. passing the sterilizing medium from the system through the unit for a given period; c. germproof closing of the two connections in the coupled state, without the same being opened, on completion of the sterilization operation. d. removing said unit from said system as a sterile unit with closed connections. All steps, including the removal of the unit, are therefore carried out in a system where the sterility obtained is constantly maintained. This "inline sterilization" guarantees a high degree of sterility of the medical units treated. This invention also relates to a technical apparatus for carrying out the method (FIG.1).
