Abstract

Machine de dialyse comportant une membrane pour séparer le sang et le dialysat. Elle comporte : un transducteur de pression de dialysat 40 qui détecte la pression du dialysat passant sur la membrane et engendre un premier signal variant en fonction de cette pression ; un transducteur de pression veineuse 70 qui détecte la pression du sang qui passe sur la membrane et qui engendre un second signal variant en fonction de cette pression; un circuit additionneur et un amplificateur qui engendrent un premier signal de circuit variant en fonction desdits premier et second signaux; et un circuit comparateur et un circuit d'alarme qui, dès que ledit premier signal de circuit dépasse un niveau donné correspondant au dépassement de la pression du sang par la pression du dialysat, déclenchent une alarme.
