  • Patent number: 4554073
    Abstract: A device for the uptake, transportation and recovery of cell material present in body fluids, cell-fixing liquids, and mixtures of body fluids and cell-fixing liquids, and also for the transfer of the recovered cell materials to microscope slides. The device comprises a vessel (1) with an inlet (2) and an outlet (3); a removable fiber element (5) is arranged, flush with the wall, in the outlet (3), and comprises fibers which are insoluble in body fluids and cell-fixing liquids and which are arranged lengthwise in the direction of the long axis of the vessel (1) with the formation of through capillaries, such that the capillaries have a smaller diameter than the diameter of the cells. The vessel (1) can be liquid-tightly and gas-tightly closed. Preferably, the fibers of the fiber element (5) are crimped and/or texturized fibers and/or hollow fibers.
