PROBLEM TO BE SOLVED: To provide a medical device that can sufficiently suppress blood clot from generating in blood extracorporeally circulating in an extracorporeal circulation circuit.SOLUTION: The medical device comprises a blood circuit 1 including an artery side blood circuit 1a and a vein side blood circuit 1b and allows blood of a patient to extracorporeally circulate from an end of the artery side blood circuit 1a to an end of the vein side blood circuit 1b, and a dialyzer 2 interposed between the artery side blood circuit 1a and the vein side blood circuit 1b of the blood circuit 1 to purify the blood flowing in the blood circuit 1. The medical device being provided with coagulation decomposing means 10 that is mounted at a predetermined position of a blood flow pass of the blood extracorporeally circulating in the blood circuit 1 to decompose coagulation of red corpuscles by oscillating ultrasonic waves with respect to the blood in the blood flow pass.SELECTED DRAWING: Figure 1 |
