Abstract

An apparatus for detecting changes in a property of a liquid/reagent mixture comprises a cartridge having a fluid receiving/dispensing reservoir, one or more fluid-receiving chambers, one or more conduit(s) that permit(s) fluid communication between the fluid receiving/dispensing reservoir and the fluid-receiving chamber(s) and wherein the one or more conduits have a constricted passage for increasing the velocity of fluid flow through said constricted passage and thereby more thoroughly mixing the liquid (e.g., human blood) and a reagent (e.g., protamine).
