METHOD OF TREATING PUS POCKETS AND IRRIGATING SOLUTION ACTIVITY TESTER Russian patent published in 2010 - IPC G01N21/00 G01N21/78 

FIELD: medicine.

SUBSTANCE: substance of the method consists in pus substratum sampling, analysed for irrigating solution reaction, and pus pocket washing with the most effective irrigating solution. The irrigating solution is analysed for efficacy in test tubes of greater surface roughness in the bottom, 1/5 filled with pus substratum. The test tubes are 3/5 filled with the irrigating solutions then, placed in a chamber and video filmed by a digital video camera transferring an image through an interface to a data processor which compares colour of the bottom filled with pus substratum and the appropriate reference colours of the irrigating solution images stored in the memory of the data processor. If the colour of the filmed image is matched with a reference colour of one of the irrigating solutions, video recording is stopped. Then time during which pus substratum moves up completely over the irrigating solution is fixed. The solution with faster pus substratum effect time is considered to be effective and used for irrigating the pus pocket of a patient to ensure a pure water effect. In the process of treatment, the irrigating solution is introduced for a period of time not smaller than time during which pus substratum moves in a test tube. An irrigating solution activity tester comprises a chamber with placed test tubes and a digital video camera connected to a data processor. The chamber has ports arranged on the same optical axis and comprising a lighter and a digital video camera. The data processor accommodates a data record and storage unit, a preset area selection unit, a comparator unit, and a timer; a heating and temperature control unit is connected to the chamber. The test tubes are marked at 1/5 and 3/5, while a lower quarter of an internal surface of the test tubes has greater roughness, than the other.

EFFECT: more effective and faster pus substratum removal from a cavity.
