Blood tends to coagulate during therapies with extracorporeal circulation like dialysis or surgery with the use of heart-lung-machines. To study the effects of the incipient coagulation and to develop new and continuous supervising methods for blood therapies, a fluid mimicking rheological and acoustical blood properties with nearly the same amount of particles as blood is necessary. We enhanced the International Electrotechnical Commission Doppler blood mimicking fluid recipe to be used at physiological hematocrit values and to mimic incipient plasma coagulation and blood clotting. This paper presents the recipe, acoustical and rheological data of the refined blood mimicking fluid.
