In this paper, we discuss the self-preserving function in the pulsation of circulation systems. Humans and many animals have circulation systems, which send blood with pulsation. However, how the pulsation is supporting the survival capability of them is not studied sufficiently. We propose an artificial circulation system that imitates homeostatic functions of natural blood circulation systems. The proposed system uses mixed fuel solution instead of blood, which is able to exclude the affection of the clotting function of blood platelet. Thus, the proposed system provides easy discussion for the affection of blood pulsation for clotting. As a result of a clotting experiment, we found the phenomena that pulsation helps clotting capability. As a result of energy supply experiment, pulsation helped smooth filtering for pure solution. These results show the importance of pulsation in artificial hearts. Also, the results are applicable to fuel supply systems so as to increase their safety.
