Abstract: To provide a storage tray in which flexible tubes are to be stored and with which the efficiency of work to be performed after priming can be improved. A storage tray that stores a flexible tube to be attached to a medical apparatus, the flexible tube allowing fluid to flow therethrough. The storage tray includes a tray body that is securable to a predetermined portion of the medical apparatus and in which the flexible tube is storable, and a receiving portion that is included in the tray body and is capable of receiving a priming solution, which is used for flushing the flexible tube attached to the medical apparatus, and storing a predetermined volume of priming solution.

Abstract: A blood purification device confirms whether a specific peak is provided by e.g. an ultrafiltration pump, to concentrate the blood or not and also accurately measures a blood re-circulation with a minimum of parameters providing a ratio of re-circulating blood. The blood purification device composed of arterial blood circuit route 1a and venous blood circuit route 1b, blood pump 3, dialyzer 2, water removal pump 8 providing the specific peak in the variation of blood concentration by removing water rapidly, and a detector detecting the specific peak, can measure the blood re-circulation thereby. The re-circulating blood flowing is the blood which was introduced again to arterial blood circuit route 1a after it had been returned to a patient from venous blood circuit route 1b. A first detector 5a installed in the arterial blood circuit route 1a and a second detector 5b installed in venous blood circuit route detector.

Abstract: A blood purification device allows confirming whether a specific peak is provided by a means, such as a ultrafiltration pump, to concentrate the blood or not and also allows measuring certainly and accurately a blood re-circulation with reduction of parameters which can provide a ratio of re-circulating blood. The blood purification device including blood circuit route 1 composed of arterial blood circuit route 1a and venous blood circuit route 1b, blood pump 3, dialyzer 2, water removal pump 8 which can provide the specific peak in the variation of blood concentration by removing water rapidly in a short period of time, and detecting means detecting said specific peak, can measure the blood re-circulation based on the specific peak detected by the detecting means. The re-circulating blood flowing is the blood which was introduced again to arterial blood circuit route 1a after it had been returned to a patient from venous blood circuit route 1b.
