CELL, METHOD AND MOULDING INSTRUMENT THEREFOR Russian patent published in 2009 - IPC G01N21/07 B01L3/00 G01N21/03 G01N33/48 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to a cell for fluid sampling and presentation of a sample for analysis. The cell for fluid sampling and presentation of a sample for analysis comprises an input cavity for receiving a sample of fluid to be analysed, a centrifugating receiving cavity and a receiving cavity for the analysed sample. The centrifugating receiving cavity is communicating with the input cavity so that to prevent spontaneous current from the input cavity to the centrifugating receiving cavity and so that to make it possible to discharge the fluid from the input cavity into the centrifugating receiving cavity by applying centrifugation force to the cell. The receiving cavity for the analysed sample is capillary connected with at least a part of the centrifugating receiving cavity to maintain the sample transportation ensured by capillary effect from the centrifugating receiving cavity into the receiving cavity for the analysed sample test. The input cavity, centrifugating receiving cavity and receiving cavity for the analysed sample are apertured through an external wall of the cell which pass full-width of these cavities respectively. The method for making said consists that it provides the basic material used to mould the cell. It is moulded with using at least one moulding instrument that is arranged so that it passes in said basic material for cell moulding with the input cavity, the centrifugating receiving cavity and the receiving cavity for analysed sample. The moulding instrument is removed through lateral wall of the cell. The moulding instrument for cell moulding is inserted in the basic material to form the cavities therein, and removed from the basic material once the cavities are formed. The moulding instrument comprises the first flange shaped as reciprocating to the input cavity the cells. The second flange is shaped as reciprocating to the centrifugating receiving cavity of the cell, and the third flange is shaped as reciprocating to the receiving cavity for the analysed sample. The second flange forms the centrifugating receiving cavity adjoining the receiving cavity, and has the thickness that prevents capillary fluid transportation from the input cavity into the centrifugating receiving cavity. The third flange forms the receiving cavity for the analysed sample adjoining the centrifugating receiving cavity, and has the thickness that provides capillary fluid transportation from the centrifugating receiving cavity into receiving cavity for the analysed sample.

EFFECT: invention provides for appropriate separation of the sample, as well as reliable and simple manufacturing of the cell.
