Abstract

Et blodviskositetsmålingssystem og fremgangsmåte som overvåker det stigende hodet til en fluidkolonne som representerer et levende vesens blod in-vivo for å bestemme blodviskositeten over et skjærområde. Systemet innbefatter et kapillærrør, minst en del av dette er anbrakt i det vaskulære systemet til vesenet, og et stigerør, som har en væske deri, koblet til kapillærrøret. En sensor og tilhørende mikroprosessor er frembrakt for å bestemme endringen i høyden av væsken i stigerøret ved flere punkter langs lengden av røret, fra hvilken viskositeten blir beregnet. _..... ............
