析時間を決定することができないという欠点がある。In the conventional artificial dialysis system described above, it is not possible to continuously check the effect of dialysis during dialysis, so a certain period of time (for example, 5
~6 hours) and the disadvantage is that it is not possible to determine the appropriate dialysis time for each individual patient.

して構成される。The artificial dialysis system with a dialysate component sensor of the present invention includes a dialyzer that purifies blood with dialysate through a dialysis membrane, a dialysate supply device that supplies dialysate to the dialyzer, and a dialysate that is collected after use. In an artificial dialysis system that is equipped with a waste fluid tank that stores the dialysate, a blood pump device that flows blood into the dialyzer, and a safety device that monitors the dialysis status, it is possible to continuously measure the concentration of components in the dialysate waste immediately after use. It is configured with a sensor section that measures the temperature.
以下、本発明について図面に基づき説明する。 Hereinafter, the present invention will be explained based on the drawings.

透析中の患者の状態をモニターする。1 is a living body, and blood flows through a blood flow path 3 in the direction of the arrow and advances to a dialyzer 4 by the drive of a blood pump 2 . The dialysate is sent by the dialysate supply device 5 to the dialyzer 4 through the dialysate channel 6, and blood purification by dialysis is performed. The purified blood is returned to the veins. The component concentration of the used dialysate waste liquid is measured by the sensor unit 7 and then supplied to the waste liquid tank 8 . 9 is a safety device;
Monitor the patient's condition during dialysis.

ある。As explained above, the present invention measures the component concentration of dialysate waste immediately after passing through a dialyzer during dialysis.
The effect of dialysis can be confirmed continuously, and conditions such as dialysis time can be determined according to the dialysis efficiency of each individual patient. This saves dialysis time and the amount of dialysate supplied.
Effects such as reducing the physical and mental burden on the patient can be obtained. Furthermore, the condition of the patient undergoing dialysis can be grasped and dealt with at any time. Furthermore, compared to the case where a sensor is provided in the blood flow path, there is an effect that the blood returning to the living body does not come into contact with foreign substances.
