FIELD: medicine.SUBSTANCE: invention refers to medical equipment, namely to a device and method for easy collection, dilution, mixing and dosing an analysis fluid in an isolated system. A sample suction and dosing unit comprises a container and a sampler. The container comprises a sealed chamber, limited at least from one side with a permeable element. The sealed chamber contains a fluid. The sampler has an open-ended passage. At least a portion of the passage extends from a first end comprising a capillary passage adsorbing the sample by a capillary action. The sampler contains a penetration unit penetrating inside the above permeable element so that the above passage is connected with the above sealed chamber after the permeable element has been perforated. The above canal is connected with the sealed chamber to allow for mixing the sample and fluid medium and dosing the mixed sample with the fluid medium from the device from the capillary passage. The method for sample suction and dosing with the use of the above device comprises the following stages: suction of a fluid sample into the above capillary passage, penetration into the above permeable element to interlock with the permeable element so that the above passage is connected with the sealed chamber, for actuation of the permeable element as a piston rod for mixing the sample and fluid medium and dosing of the mixed sample and fluid from the device through the capillary passage.EFFECT: present invention may be used in a combination with a number of testers for chemical, biochemical or biomedical qualitative or quantitative analysis within clinical and hygienic studying.24 cl, 23 dwgИзобретение относится к медицинской технике, а именно к устройству и способу легкого сбора, разбавления, перемешивания и дозирования жидкостей для анализа в изолированной системе.
