Introduces the myocardial protective fluid filled in the reservoir 52 into the heat exchanger 53 via the liquid sending line 60, cools it, returns it to the reservoir 52 via the injection line 62 and the circulation line 65, and circulates between them. Meanwhile, the switching valve 58 was opened as necessary to inject the patient into the coronary artery via the injection line 63. However, since the circulation path of the myocardial protective solution extends over the entire area of the injection line 62 and the circulating line 65 provided from the machine side to the operator side, the cooling efficiency of the myocardial protective solution was poor. Thus, the present invention has conducted intensive studies in order to solve the above problems, and as a result, has arrived at the following invention.
