Method and device for the determination of the presence of microorganisms in body liquors.

摘要

The invention pertains to a method for the determination of the presence of microorganisms in body liquors and to a diagnosis column for performing this method. Body liquor is allowed to flow through the column packed with a sorbent, and trapped microorganisms are then cultivated in a culture medium which is charged directly into the column. After activation, the culture medium is sucked off from the column, and the presence of microorganisms is determined by known methods in the column. The diagnosis column is made from a biocompatible material, has a smooth inner surface advantageously provided with longitudinal ribs (6), its jacket consisting of a cylindrical body (1) and conical terminals (5), and is packed with a sorbent (4) placed between partitions (2, 3) from a porous material, which advantageously have various porosity, whereas the volume ratio of the cylindrical body (1) to that of the conical terminals (5) is in the range of 1:0,3 to 1:5, and the total inner volume is 30 to 300 ml. The partition (2) at the outlet terminal is advantageously formed from several layers having different porosities.
