DEVICE AND METHOD FOR AUTOMATIC RESEARCH OF BLOOD SAMPLES Russian patent published in 2009 - IPC G01N33/49 G01N35/10 

FIELD: medicine.

SUBSTANCE: invention concerns the device and the method for automatic research of blood samples. The device for automatic research of blood samples contains a technological position (I) of sampling on which blood gets from the collection (40) by means of an intake, a measuring technological position (II) on which the taken away blood is referred through the aperture (26, 99) located in a measuring part (9, 90) diaphragms (30, 98), thus the measuring part (9, 90) is bridged to an intake, and a reception technological position (III) on which the measuring parts executed in the form of disposable parts (9, 90 are given) and are bridged to an intake. Besides the device for automatic research of blood samples contains the device for intake moving between sampling position (I), measuring position (II) and reception position (III). The intake has a needle part (15) which is executed with possibility of bond with (III) measuring part (90) given on a reception position, or includes a needle part (15) and a head part (46) which is executed with possibility of bond with (III) measuring part given on a reception position (9). On the sampling position (I) blood is entered into a needle part (15), and on a measuring position (II) blood through a head part (46) moves to a measuring part (9). The valve (10) is provided to establish alternate bond with the needle part (15) or with the head part (45). The method for automatic research of blood samples is characterised by that for intake moving the sampling device to the sampling position (I) by means of the first drive (4). The second drive (11) is put in action on a sampling position (I) for lowering of a keeping part (13) and a needle part (15). After immersing of a needle part (15) in blood containing in the collection (40) put in action the third drive (51) reception tanks (50) so that through a needle part (15), a tubular part (16) and the pipeline (14) blood is soaked up in the reception tank (50), and other valve (18) establishes bond between the pipeline (14) and the reception tank (50). Further the lever (3) is move to a reception position (III) by means of actuating of the first drive (4). Thus to the collecting device (7) for extraction of a measuring part (9; 90) is lower of the keeping part (13) moved earlier upwards by means of the second drive (11) by means of actuating of the second drive (11) so, that a measuring part (9; 90) it is tightly bridged to a head part (46) or with a needle part (15). After reception of the measuring part (9) the second drive (11) is put in action for moving of the keeping part (13) and for extraction of a measuring part (9; 90) from the collecting device (7). The lever (3) by means of the first drive (4) is moved to a measuring position (II). And the reception tank (50) is put in action by means of the third drive (51) so that blood constantly proceeds through the aperture (26) of the measuring parts (9; 90) also leaves this part through letting out blood area (31).

EFFECT: simplifying of the device at simultaneous maintenance of more economic researches.
