COMBINED MEASURING SYSTEM TO ANALYSE SUBSTANCES IN BIOLOGICAL FLUIDS AND CARTRIDGES TO PERFORM COMBINED GENERAL CHEMICAL AND SPECIFIC ANALYSES OF BINDING Russian patent published in 2009 - IPC B01L3/00 G01N33/543 

FIELD: instrument making.

SUBSTANCE: set of invention relates to devices to determine the level of analysed substances in biological fluids. Proposed system comprises (a) measuring device with housing, logical circuit arranged in said housing, visual display arranged on said housing and measuring system arranged therein. It comprises also (b) cartridge incorporating at least one test strip to analyse lateral flow. Note here that said test strip incorporates (i) lateral flow transport matrix, (ii) zone of analysing specific binding on transport matrix to take up fluid specimen to produce required reaction, and (iii) zone of general chemical analysis on transport matrix to take up fluid specimen to produce required reaction. Note also that sizes of cartridges are selected to allow arranging analysed biological fluid substances in measuring device so that measuring system in above described zones on test strip. Mind that transport matrix first and second segments are made from different materials and bound so that said segments does not allow the product formed on first segment to contribute into reaction on second segment. Proposed invention covers other versions of aforesaid device.

EFFECT: higher efficiency, accuracy and reliability.
