Abstract:
1. A blood testing system for testing the compatibility of blood with different test substances, said system comprising: a plurality of canisters initially containing a corresponding one of the test substances; a plurality of canister holders, each canister holder to hold a single canister; a displacement assembly comprising a drum housing the plurality of canister holders, said displacement assembly moving each of the plurality of canisters to a sampling stage, a reagent adding stage, and an optical detector stage; a blood divider assembly at the sampling stage, said blood divider assembly configured to add a predetermined amount of the blood to each of the plurality of canisters containing the corresponding test substances as the canisters are moved to the sampling stage; a reagent divider assembly at the reagent adding stage, said reagent divider assembly configured to add a predetermined amount of luminescent reagent to each of the plurality of canisters as the canisters are moved to the reagent adding stage; an electro-optical multiplier assembly at the optical detector stage, the electro-optical multiplier assembly configured to measure luminescence of each of the plurality of canisters at a predetermined time period after the luminescent reagent has been added to the corresponding canister; a central controller configured to control the functions of the displacement assembly, the blood divider assembly, the reagent divider assembly and the electro-optical multiplier assembly and to process data received therefrom and assess the compatibility of the blood to each of the test substances; the electro-optical multiplier assembly comprises an electro-optical multiplier, and at least one photosensitive cathode wherein the photosensitive cathode detects luminescence in the optical detector stage, and wherein the electro-optical multiplier transforms the luminescence detected by the photosensitive cathode into a luminescence signal and transmits the luminescence signal to the central controller; a display; the central controller processes the data to assess the compatibility of blood to each of the test substances by receiving the luminescence signal for each of the plurality of canisters, correlates the luminescence signal to the corresponding test substance and generates a compatibility output on the display for each test substance based on the luminescence signal; and the luminescence signal comprises at least 3 luminescence sample measurements for each of the plurality of canisters, and, the central controller generating the compatibility output for each of the test substances by determining a root mean square deviation of each of the at least 3 measurements and generating a neutral compatibility output for the test substance if none of the sample measurements are outside of two times the root mean square, generating a mild compatibility output for the test substance if at least one of the sample measurements are outside of two times the root mean square, and generating a severe incompatibility output for the test substance if at least one of the sample measurements is outside of three times the root mean square; wherein the drum is in cooperative engagement with the blood divider, the reagent divider, and the electro-optical multiplier assembly.
