MECHANICAL DEVICE FOR MIXING THE SAMPLE OF THE LIQUID MEDIUM WITH PROCESSING SOLUTION Russian patent published in 2012 - IPC G01N1/18 

FIELD: measurement.

SUBSTANCE: device is comprised of the first and second part. The first part contains the edge piercing the membrane, capillary channel and a hole in the outer surface of the first part. The second part comprises the chamber for processing solution and the membrane closing the chamber for processing solution. Wherein the hole is opened when the first part of the device is initially put into the second part of the device, and the hole is closed when the first part of the device is fully put into the second part of the device. Capillary channel made in the first part of the device is sized for receiving the liquid medium sample. The second part is comprising the chamber for processing solution that can be limited by first and second membranes, wherein the first part gets through the first membrane when the first part is put into the second par in such a way that the content of processing solution chamber is mixed with the content of capillary channel. The tool for piercing the second membrane is made in such a way that the content of processing solution chamber and capillary channel can be forced out of the device. The device can also comprise the plunger with the mechanism for getting through the second membrane in such way that the content of processing solution chamber and capillary channel is forced through the plunger.

EFFECT: increased pressure control in the device when supplying necessary amount of sample into analyzing cartridge.
