人工透析器を利用した血液透析を行うに当たり、腎不全等の患者の血液中の水 分や老廃物を除去する目的で使用する透析装置は、血液の体外循環回路上のポン プで血液流量を一定に調整し、透析液は人工透析装置内のポンプによりシングル パス方式にて一定量に調整し、血液と透析液は人工透析器の半透膜を介して正又 は逆方向に流れることにより、血液中の水分や老廃物を除去する方法によってい た。又 水分や老廃物の除去量は血液流量と透析液流量が関与している。 When performing hemodialysis using an artificial dialyzer, the dialysis machine used to remove water and waste products from the blood of patients with renal failure, etc., uses a pump on the extracorporeal circulation circuit to change the blood flow rate. By adjusting the dialysate to a constant amount by the single-pass method with the pump in the artificial dialyzer, the blood and dialysate flow in the forward or reverse direction through the semipermeable membrane of the artificial dialyzer. , By removing water and waste products from the blood. Further, the flow rate of blood and the flow rate of dialysate are involved in the removal amount of water and waste products.

従来の人工透析器を利用した血液透析の場合、血液流量及び透析液流量は、装 置内のポンプによりシングルパス方式によって一定に調整されている為、人工透 析器の十分な性能を導き出すことに至っていない。 人工透析器の性能を導き出すために、半透膜を介した血液と透析液において人工 透析器を通過した老廃物を含有して飽和状態になっていない透析液を利用し、人 工透析器より流出する透析液を再循環させることにより人工透析器を利用した老 廃物の除去量を増加させる。 In the case of hemodialysis using a conventional artificial dialyzer, the blood flow rate and the dialysate flow rate are constantly adjusted by the single-pass method by the pump inside the equipment, and therefore sufficient performance of the artificial dialyzer should be derived. Has not reached. In order to derive the performance of an artificial dialyzer, a dialysate that is not saturated because it contains waste products that have passed through the artificial dialyzer in blood and dialysate through a semipermeable membrane is used. By recirculating the outflowing dialysate, the amount of waste removed using the artificial dialyzer is increased.

【課題を解決する為の手段】 この目的を達成するために、考案は次のような構成をしている。 すなわちこの考案に係る透析装置は、人工透析器を利用した血液透析を行う際に 、人工透析器内に流入する透析液ラインと流出するラインにポンプを備えたバイ パスラインを設け、ポンプの回転により流量とバイパスラインの透析液を調整す ることにより、人工透析器内に流入する透析液流量を血液流量の変化に伴い調整 制御出来るようにしたことを特徴とする。[Means for Solving the Problems] In order to achieve this object, the invention has the following configuration. That is, when performing hemodialysis using an artificial dialyzer, the dialyzer according to the present invention is provided with a bypass line equipped with a pump for the dialysate line flowing into the artificial dialyzer and a line flowing out of the artificial dialyzer, and the pump is rotated. By adjusting the flow rate and the dialysate in the bypass line, the flow rate of dialysate flowing into the artificial dialyzer can be adjusted and controlled as the blood flow rate changes.

この考案の実施例を図面１を参照しながら説明する。 Ｃ１のポンプにより腎不全の患者の血液流量を変化させた時、透析液側バイパス 回路内のポンプを制御出来る装置である。 例えば、Ｃ１のポンプにより血液は−１から−１へと流れ、血液流量を２０ ０ｍｌ／ｍｉｎに、ポンプＡ１により透析液は−１から−１へと流れ、透析 液流量を５００ｍｌ／ｍｉｎに設定し（血液除水量は０ｍｌ／ｍｉｎとする）、 ポンプＢは停止状態とする。人工透析器の半透膜を介した血液・水分及び老廃物 の除去が低下した時、人工透析器に流入する透析液量を血液流量に適応した透析 液流量になるようにポンプＢ１の回転数を制御する。この時の透析流量は−１ ライン流量＝−１ライン流量で、−１ライン流量＋−１ライン流量＝− １ライン流量＝−１ライン流量となるように流れる。 例では、血液流量・透析液流量の変化は同時に行っているか、血液流量・透析 液流量の一方の変化のみでも老廃物の除去効率は上がるが同時に行った方がさら に効率が上がる。 利用範囲中において図２のような透析装置のタイプもあるので、上記の実施例に 限るものではない。An embodiment of this invention will be described with reference to FIG. It is a device that can control the pump in the dialysate side bypass circuit when the blood flow rate of a patient with renal failure is changed by the C 1 pump. For example, the pump of C 1 causes blood to flow from -1 to -1, the blood flow rate to 200 ml / min, the pump A 1 to cause dialysate flow from -1 to -1, and the dialysate flow rate of 500 ml / min. (The amount of water removed from the blood is set to 0 ml / min), and the pump B is stopped. When the removal of blood, water and waste products through the semi-permeable membrane of the artificial dialyzer is reduced, rotate the pump B 1 so that the volume of dialysate flowing into the artificial dialyzer becomes a dialysate flow rate adapted to the blood flow rate. Control the number. The dialysis flow rate at this time is -1 line flow rate = -1 line flow rate, and -1 line flow rate + -1 line flow rate = -1 line flow rate = -1 line flow rate. In the example, the blood flow rate and dialysate flow rate are changed at the same time, or only one of the blood flow rate and the dialysate flow rate is changed, but the removal efficiency of waste products is improved, but the efficiency is further improved when they are changed at the same time. Since there is a type of dialysis device as shown in FIG. 2 within the range of use, the present invention is not limited to the above embodiment.
