Abstract: For the purpose of obtaining medical preparations by means of a printing technique, a specimen cylinder is provided with a syringe cone segment that can be separated from a cylinder segment. After the syringe cone segment has been removed, a filtering device with a filter which is held so as to be sealed relative to the inner wall of the specimen cylinder projects beyond its holder and beyond the cylinder segment in an operational position of the filtering device and can be pressed onto a specimen carrier in a simple manner.

Abstract: For the purpose of obtaining medical preparations by means of a printing technique, a specimen cylinder (1) is provided with a syringe cone segment (2) that can be severed from a cylinder segment (2), so that preferably after the syringe cone segment has been removed a filtering device (6) with a filter (8) which is held so as to be sealed relative to the inner wall (7) of the specimen cylinder (1) projects by a surface (9) axially over its holder (5) and over the cylindersegment (2) in an operational position of the filtering device (6) and can be pressed onto a specimen carrier in a simple manner.

Abstract: A method for preparing and preserving a personal cell bank, including the step of adding a preserving agent to a test material.

Abstract: A method and apparatus for collecting and separating cells, particles or the like from body fluid or the like for microscopic diagnosis is disclosed. Fluid is sucked by capillary action through a fluid-permeable surface (17) which holds back the cell material to be investigated. An apparatus suitable for this purpose comprises a filter container (2) having an upper and a lower opening, the lower opening of which is covered by a fluid-permeable cell carrier element (10), at least one filter segment (11) and a suction insert (12) being arranged in the filter container (2).

Abstract: A device for urinalysis, in particular for microscopic quantitative analysis of urinary sediment, consists of a cylindrical specimen container with an opening at the top and a pipette tip at the bottom end, a tubular plunger inserted into this specimen container and moveable therein in a leakproof manner, both parts consisting of transparent material, a stopper for the specimen container at the top end and a sealing cap for the pipette tip, a single-stage or multi-stage filter arrangement being located in the plunger close to the bottom end.

Abstract: An apparatus for the recovery of cell material from body fluids is described which consists of a filter with a filter material arranged in one or more layers and not soluble in cell-fixing liquids, such as isopropanol. The filter material consists of a single textured or crimped filament yarn. Preferably, the filaments of the filament yarn are made of synthetic polymers. In contrast to the known apparatus, consisting essentially of a filter cartridge which contains as filter material synthetic fibers dissolvable in alcohol or in an alcohol-water mixture, the use of the apparatus of this invention produces a cell sample which is not interspersed with particles of the filter material. Besides, the present invention permits to achieve very low cell losses, and cell damage does not occur. Body fluids from which cell material may be recovered with the apparatus according to this invention are for example, urine, liquor, pleural effusions or fluids from the abdomen area.

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.

Abstract: A device for collecting cell material from a body cavity includes a guide tube and a cell sampler which is retractable into the guide tube, which has a front portion and a back portion. The cell sampler has the shape of an inflatable balloon which is retractable into itself and pulled over the end of the front portion of the guide tube. The device also has an inflation means for introducing gas into the sampler to inflate it. Retraction means, which passes through the guide tube and is connected with the inner wall of the balloon-type cell sampler, has been provided for retracting the cell sampler into the guide tube.

Abstract: A polymer carrier for scientific, analytical or diagnostic examinations. The carrier consists of a soluble polymer in which the materials to be examined and/or required for examinations are incorporated and which is fully dissolved for complete release of said materials.
