Description

本発明は、血液浄化システムに関する。   The present invention relates to a blood purification system.

血液浄化療法は、患者の血液を体外に取り出し、この血液を血液浄化器で浄化した後、再び体内に戻す治療方法であり、その代表例としては透析療法が挙げられる(特許文献1)。透析療法では、患者血液と透析液を血液浄化器の半透膜を介して接触させ、物質の濃度差により生じる拡散現象を利用して患者血液中から不要物質を透析液側に排出させる。拡散現象のみでは除去できない大分子量の不要物質についてはろ過により排除を行う。透析療法の他、難治性の自己免疫疾患に対して多様な血液浄化療法が保険適応対象となっている。例えば、患者血液から白血球を除去することにより、潰瘍性大腸炎、クローン病、慢性関節リウマチなどの症例を劇的に改善することができる(特許文献2)。これらの血液浄化療法に使用する多様な血液浄化器は、上述した拡散、ろ過といった物質分離の特性の他、吸着性を利用して物質分離を行うものもある。   Blood purification therapy is a treatment method in which a patient's blood is taken out of the body, this blood is purified with a blood purifier, and then returned to the body. A typical example is dialysis therapy (Patent Document 1). In dialysis therapy, patient blood and dialysate are brought into contact with each other through a semipermeable membrane of a blood purifier, and unnecessary substances are discharged from the patient blood to the dialysate side using a diffusion phenomenon caused by a difference in substance concentration. Unnecessary large molecular weight substances that cannot be removed only by diffusion are removed by filtration. In addition to dialysis therapy, various blood purification therapies for intractable autoimmune diseases are covered by insurance. For example, by removing leukocytes from patient blood, cases such as ulcerative colitis, Crohn's disease, and rheumatoid arthritis can be dramatically improved (Patent Document 2). Various blood purifiers used for these blood purification treatments also use the adsorptivity to separate substances in addition to the above-described substance separation characteristics such as diffusion and filtration.

血液浄化療法は、患者血液を体外に取り出し、この血液を血液浄化器で浄化した後、再び体内に戻すという治療の態様上、その治療時間は少なくとも1時間以上、通常は数時間、治療によっては数十時間を要する。特に、長時間の治療を要する血液浄化療法の例として、持続緩徐式血液浄化法が挙げられる(特許文献3)。持続緩徐式血液浄化法には、持続的血液ろ過法、持続的血液透析法、または持続的血液ろ過透析法などの各種の治療態様があり、救急・集中治療領域において、重篤な循環器系の合併症を有する腎疾患や多臓器不全等の治療に適用される。いずれも、「持続緩徐式」といわれる通り、通常、一回の治療に数日から長い場合は1週間以上の時間をかけながら、徐々に血液浄化が行われる。   In blood purification therapy, the patient's blood is taken out of the body, the blood is purified with a blood purifier, and then returned to the body. The treatment time is at least 1 hour, usually several hours, depending on the treatment. Dozens of hours are required. In particular, as an example of blood purification therapy that requires long-term treatment, there is a continuous slow blood purification method (Patent Document 3). Continuous slow blood purification methods include various treatment modes such as continuous hemofiltration, continuous hemodialysis, or continuous hemodiafiltration. It is applied to the treatment of renal diseases with multiple complications and multiple organ failure. In both cases, as it is said to be “sustained and slow”, blood purification is usually carried out gradually over a period of one week or more if a single treatment is performed for several days to a long time.

ところで、血液浄化治療を行う血液浄化装置は、透析液などの浄化液が貯留された浄化液バッグを有し、浄化液バッグは、装置の支柱に吊るされ、当該浄化液バッグから血液浄化器に浄化液が供給されて、血液浄化治療が行われている。よって、血液浄化治療中に、浄化液バッグが空になると、新しい浄化液バッグに交換する必要がある。   By the way, a blood purification apparatus that performs blood purification treatment has a purification liquid bag in which a purification liquid such as dialysate is stored, and the purification liquid bag is suspended from the column of the apparatus, and the blood purification apparatus is connected to the blood purification apparatus. Purified liquid is supplied and blood purification treatment is performed. Therefore, when the purification solution bag becomes empty during the blood purification treatment, it is necessary to replace it with a new purification solution bag.

上述のように血液浄化治療は、患者血液を体外に取り出し、この血液を血液浄化器で浄化した後、再び体内に戻すという血液浄化療法の原理上、その治療時間は少なくとも1時間以上、通常は数時間、治療によっては数十時間を要する。このため、一回の治療中に浄化液バッグを複数回交換する必要がある。特に、上述の持続緩徐式血液浄化療法では、数日から長い場合は1週間以上の時間をかけて治療を継続するため、治療途中に多数回の浄化液バッグの交換が必要になる。この結果、医師や看護師の負担が大きく、特に、夜間等の交換では負担が増す。また、夜間でも交換が可能なように看護師を常駐配置しなければならず、人件費が高くなり、病院経営における血液浄化治療の高コスト化の原因となっている。   As described above, the blood purification treatment takes the patient's blood outside the body, purifies the blood with a blood purifier, and then returns it to the body again. It takes several hours and several tens of hours depending on the treatment. For this reason, it is necessary to exchange the cleaning solution bag a plurality of times during one treatment. In particular, in the above-mentioned continuous slow blood purification therapy, the treatment is continued over a period of one week if it is several days or longer, so that it is necessary to change the purification solution bag many times during the treatment. As a result, the burden on doctors and nurses is large, and the burden increases especially when exchanging at night. In addition, nurses have to be resident so that they can be replaced at night, which increases labor costs and increases the cost of blood purification treatment in hospital management.

本発明はかかる点に鑑みてなされたものであり、長時間の血液浄化治療における浄化液バッグの交換による医師や看護師の負担を軽減し、血液浄化治療の低コスト化を実現することをその目的とする。   The present invention has been made in view of the above points, and reduces the burden on doctors and nurses due to replacement of the purifying fluid bag in long-term blood purification treatment, and realizes cost reduction of blood purification treatment.

通信手段4は、例えば血液浄化装置1と浄化液生成装置2にそれぞれ、情報通信のインターフェイスとなる通信部110、111を有している。通信部110、111は、互いに有線、或いは無線により通信できる。有線の場合には、血液浄化装置1と浄化液生成装置2が連結、離脱可能になるように、情報線が通信部110、111間で連結、離脱できるようになっている。通信手段4は、浄化液バッグ50の浄化液の液量が所定の下限閾値以下になったときに、浄化液生成装置2の浄化液が浄化液補充回路3を通じて浄化液バッグ50に補充されるように、血液浄化装置1と浄化液生成装置2との間で信号のやり取りを行う。   The communication unit 4 includes, for example, communication units 110 and 111 that serve as interfaces for information communication in the blood purification device 1 and the purification liquid generation device 2, respectively. The communication units 110 and 111 can communicate with each other by wire or wirelessly. In the case of a wired connection, the information line can be connected and disconnected between the communication units 110 and 111 so that the blood purification device 1 and the purification liquid generating device 2 can be connected and disconnected. The communication means 4 replenishes the purifying liquid bag 50 with the purifying liquid of the purifying liquid generating device 2 through the purifying liquid replenishing circuit 3 when the amount of the purifying liquid in the purifying liquid bag 50 becomes a predetermined lower limit threshold or less. As described above, signals are exchanged between the blood purification apparatus 1 and the purification liquid generation apparatus 2.

具体的には、血液浄化装置1の制御装置14が、重量計80による浄化液バッグ50の重量をモニタリングし、浄化液バッグ50の浄化液の液量が所定の下限閾値以下になったときに、当該浄化液の液量低下情報が制御装置14から通信部110に出力される。通信部110は、当該液量低下情報を浄化液生成装置2側の通信部111に送信し、通信部111は、当該情報を制御装置95に出力する。制御装置95は、当該液量低下情報に基づいて、チューブポンプ100を駆動させ、浄化液生成装置2から浄化液バッグ50への浄化液の補充を行う。また、浄化液バッグ50の浄化液の液量が所定の上限閾値になったときには、当該浄化液の液量上限情報が制御装置14から通信部110に出力される。通信部110は、当該液量上限情報を浄化液生成装置2側の通信部111に送信し、通信部111は、当該情報を制御装置95に出力する。制御装置95は、当該液量上限情報に基づいて、チューブポンプ100を停止させ、浄化液生成装置2から浄化液バッグ50への浄化液の補充を停止する。   Specifically, when the control device 14 of the blood purification device 1 monitors the weight of the purification solution bag 50 by the weight scale 80, and the amount of the purification solution in the purification solution bag 50 becomes a predetermined lower limit threshold or less. The liquid amount reduction information of the purification liquid is output from the control device 14 to the communication unit 110. The communication unit 110 transmits the liquid amount reduction information to the communication unit 111 on the purification liquid generating device 2 side, and the communication unit 111 outputs the information to the control device 95. The control device 95 drives the tube pump 100 based on the liquid amount lowering information, and replenishes the purification solution bag 50 from the purification solution generator 2. In addition, when the amount of the cleaning liquid in the cleaning liquid bag 50 reaches a predetermined upper limit threshold, the upper limit information of the cleaning liquid is output from the control device 14 to the communication unit 110. The communication unit 110 transmits the liquid amount upper limit information to the communication unit 111 on the purification liquid generating device 2 side, and the communication unit 111 outputs the information to the control device 95. The control device 95 stops the tube pump 100 based on the liquid amount upper limit information, and stops the replenishment of the purifying liquid from the purifying liquid generating device 2 to the purifying liquid bag 50.

例えば血液浄化装置1と浄化液生成装置2には、各々にキャスター115が設けられ、各々が独立して移動できる。   For example, the blood purification apparatus 1 and the purification liquid production apparatus 2 are each provided with a caster 115, and each can move independently.

次に、以上のように構成された血液浄化システムAの動作の一例を説明する。持続緩除式の血液浄化処理において、チューブポンプ30、60、61、71が稼働する。これにより、患者の血液が、採血穿刺部20から採血流路21を通って血液浄化器10の一次側41に送られる。また、透析液である浄化液が浄化液バッグ50から浄化液供給流路51を通って血液浄化器10の二次側42に送られる。血液浄化器10では、浸透圧により、一次側41の血液中の不要物質が中空糸膜40を通過し、二次側42に流入して血液が浄化される。浄化された血液は、返血流路23を通って返血穿刺部22から患者に戻される。また、血液浄化器10の二次側42において不要物質を取り込んだ浄化廃液は、浄化廃液排出回路53を通って浄化廃液バッグ52に収容される。また、補液バッグ70からは、補液が補液回路13を通じて返血回路23の血液中に供給され、血液浄化器10で減少した分の血中の水分が補充される。   Next, an example of operation | movement of the blood purification system A comprised as mentioned above is demonstrated. The tube pumps 30, 60, 61, 71 operate in the continuous gradual blood purification process. Thereby, the blood of the patient is sent from the blood collection puncture unit 20 to the primary side 41 of the blood purifier 10 through the blood collection channel 21. In addition, a purification solution that is a dialysis solution is sent from the purification solution bag 50 to the secondary side 42 of the blood purification device 10 through the purification solution supply channel 51. In the blood purifier 10, unnecessary substances in the blood on the primary side 41 pass through the hollow fiber membrane 40 by the osmotic pressure and flow into the secondary side 42 to purify the blood. The purified blood is returned to the patient from the blood return puncture unit 22 through the blood return channel 23. Further, the purified waste liquid that has taken in unnecessary substances on the secondary side 42 of the blood purifier 10 is stored in the purified waste liquid bag 52 through the purified waste liquid discharge circuit 53. Further, from the replacement fluid bag 70, the replacement fluid is supplied into the blood of the blood return circuit 23 through the replacement fluid circuit 13, and the reduced amount of water in the blood is replenished by the blood purifier 10.

血液浄化処理中、重量計80により浄化液バッグ50内に浄化液の液量がモニタリングされる。そして、浄化液バッグ50内の浄化液の液量が所定の下限閾値以下になると、その液量低下情報が通信部110から通信部111に送られる。浄化液の液量低下情報を受信した浄化液生成装置2では、チューブポンプ100が駆動し、混合タンク93の浄化液が浄化液供給流路51に送られる。浄化液供給流路51では、チューブポンプ60により血液浄化器10側への流れが制限されているため、浄化液供給流路51に流入した浄化液は、浄化液バッグ50内に流入する。なお、このとき、例えばチューブポンプ60は稼働し続けており、血液浄化処理が中断されない。そして、浄化液バッグ50内の浄化液の液量が所定の上限閾値になったときに、当該液量上限情報が通信部110から通信部111に送られ、チューブポンプ100が停止される。これにより、浄化液生成装置2から血液浄化装置1への浄化液の供給が停止され、浄化液バッグ50への浄化液の補充が終了する。   During the blood purification process, the weight of the purification liquid is monitored in the purification liquid bag 50 by the weight meter 80. Then, when the amount of the purifying liquid in the purifying liquid bag 50 becomes equal to or less than a predetermined lower threshold, the liquid amount lowering information is sent from the communication unit 110 to the communication unit 111. In the purified liquid generating apparatus 2 that has received the liquid amount reduction information of the purified liquid, the tube pump 100 is driven, and the purified liquid in the mixing tank 93 is sent to the purified liquid supply channel 51. In the purification liquid supply flow path 51, the flow toward the blood purifier 10 side is restricted by the tube pump 60, so the purification liquid that has flowed into the purification liquid supply flow path 51 flows into the purification liquid bag 50. At this time, for example, the tube pump 60 continues to operate, and the blood purification process is not interrupted. Then, when the amount of the purification liquid in the purification liquid bag 50 reaches the predetermined upper limit threshold, the liquid amount upper limit information is sent from the communication unit 110 to the communication unit 111, and the tube pump 100 is stopped. Thereby, supply of the purification liquid from the purification liquid production | generation apparatus 2 to the blood purification apparatus 1 is stopped, and replenishment of the purification liquid to the purification liquid bag 50 is complete | finished.

本実施の形態によれば、血液浄化装置1に浄化液生成装置2を接続して、浄化液バッグ50を交換せずに自動で浄化液の補充を行うことができる。これにより、血液浄化治療中に人が浄化液バッグ50を交換する必要がなく、長時間の血液浄化治療における医師や看護師の負担を軽減し、血液浄化治療の低コスト化を実現できる。   According to the present embodiment, it is possible to automatically replenish the purifying liquid without replacing the purifying liquid bag 50 by connecting the purifying liquid generating apparatus 2 to the blood purifying apparatus 1. This eliminates the need for a person to replace the cleaning solution bag 50 during blood purification treatment, reduces the burden on doctors and nurses in long-time blood purification treatment, and realizes cost reduction of blood purification treatment.

また、本実施の形態によれば、浄化液補充回路3が浄化液回路12における浄化液バッグ50とチューブポンプ60との間に接続されている。これにより、チューブポンプ60が浄化液回路12の血液浄化器10側への流れを制限するので、例えば浄化液補充回路3を浄化液バッグ50に直接接続しなくても浄化液回路12に接続して、浄化液を好適に補充できる。この結果、従来から用いられていた構造の浄化液バッグ50をそのまま使用できる。また、チューブポンプ60と浄化液バッグ50との間が閉鎖系になっているので、チューブポンプ60を稼働させ、所定量の浄化液を血液浄化器10に供給しながら、浄化液バッグ50に浄化液を補充することができる。したがって、血液浄化処理を中断せずに浄化液の補充を行うことができるので、血液浄化治療の時間を短縮し、患者への負担も低減できる。なお、浄化液補充回路3は、必ずしも浄化液回路12における浄化液バッグ50とチューブポンプ60との間に接続されている必要はなく、浄化液バッグ50に直接接続されていてもよい。また、血液浄化処理を一旦中断して浄化液の補充を行ってもよい。   Further, according to the present embodiment, the purification liquid replenishment circuit 3 is connected between the purification liquid bag 50 and the tube pump 60 in the purification liquid circuit 12. As a result, the tube pump 60 restricts the flow of the purifying fluid circuit 12 toward the blood purifier 10, so that, for example, the purifying fluid replenishing circuit 3 is connected to the purifying fluid circuit 12 without being directly connected to the purifying fluid bag 50. Thus, the cleaning liquid can be suitably replenished. As a result, the purifying solution bag 50 having a conventionally used structure can be used as it is. Further, since the space between the tube pump 60 and the purifying fluid bag 50 is a closed system, the purifying fluid bag 50 is purified while the tube pump 60 is operated and a predetermined amount of purifying fluid is supplied to the blood purifier 10. The liquid can be replenished. Therefore, since the purification solution can be replenished without interrupting the blood purification treatment, the time for blood purification treatment can be shortened and the burden on the patient can be reduced. The purification liquid replenishment circuit 3 is not necessarily connected between the purification liquid bag 50 and the tube pump 60 in the purification liquid circuit 12, and may be directly connected to the purification liquid bag 50. Further, the blood purification process may be temporarily interrupted to replenish the purification liquid.

本実施の形態によれば、浄化液バッグ50に重量計80を設け、通信手段4が、重量計80により検出された浄化液バッグ50の浄化液の液量に基づいて、浄化液生成装置2の浄化液が浄化液バッグ50に補充されるように、血液浄化装置1と浄化液生成装置2との間で情報の通信を行うので、浄化液バッグ50への浄化液の補充を適切なタイミングで好適に行うことができる。   According to the present embodiment, the purification liquid bag 50 is provided with the weight meter 80, and the communication unit 4 determines the purification liquid generator 2 based on the amount of the purification liquid in the purification liquid bag 50 detected by the weight meter 80. Since the information is communicated between the blood purification device 1 and the purification solution generator 2 so that the purification solution 50 is replenished in the purification solution bag 50, the purification solution is replenished to the purification solution bag 50 at an appropriate timing. Can be suitably performed.

血液浄化装置1と浄化液生成装置2には、各々にキャスター115が設けられており、各々が独立して移動可能であるので、血液浄化装置1と浄化液生成装置2を切り離して個別に移動させることができる。これにより、必要に応じて血液浄化装置1と浄化液生成装置2を着脱することができる。   The blood purification apparatus 1 and the purification liquid generation apparatus 2 are each provided with a caster 115 and can be moved independently of each other, so that the blood purification apparatus 1 and the purification liquid generation apparatus 2 are separated and moved individually. Can be made. Thereby, the blood purification apparatus 1 and the purification liquid production | generation apparatus 2 can be attached or detached as needed.

なお、浄化液生成装置2における浄化液の生成は、例えば混合タンク93の液量が低下したときに適宜行われてもよいし、浄化液バッグ80に浄化液を補充するときに行われてもよし、その両方であってもよい。   Note that the generation of the purification liquid in the purification liquid generator 2 may be performed as appropriate when, for example, the amount of liquid in the mixing tank 93 is reduced, or may be performed when the purification liquid bag 80 is replenished with the purification liquid. Okay, both.

以上の実施の形態において、図2に示すように血液浄化システムAが、浄化廃液バッグ52の浄化廃液を浄化液生成装置2に回収するために、血液浄化装置1の浄化液回路12と浄化液生成装置2とを接続する浄化廃液回収回路120をさらに有していてもよい。浄化廃液回収回路120は、例えば浄化液生成装置2に設けられた浄化廃液タンク121から浄化廃液排出流路53に接続されている。浄化廃液回収回路120は、浄化廃液バッグ52とチューブポンプ61との間に接続されている。浄化廃液回収回路120には、チューブポンプ122が設けられている。浄化廃液バッグ52には、バッグ内の浄化廃液の液量を検出する浄化廃液検出部としての重量計123が設けられている。重量計123による計測結果は、制御装置14に出力される。   In the above embodiment, as shown in FIG. 2, the blood purification system A collects the purification waste liquid in the purification waste liquid bag 52 in the purification liquid generator 2, so that the purification liquid circuit 12 and the purification liquid of the blood purification apparatus 1 are used. You may further have the purification waste liquid collection circuit 120 which connects the production | generation apparatus 2. FIG. The purified waste liquid recovery circuit 120 is connected to the purified waste liquid discharge channel 53 from, for example, a purified waste liquid tank 121 provided in the purified liquid generator 2. The purified waste liquid recovery circuit 120 is connected between the purified waste liquid bag 52 and the tube pump 61. The purified waste liquid recovery circuit 120 is provided with a tube pump 122. The purification waste liquid bag 52 is provided with a weighing scale 123 as a purification waste liquid detection unit that detects the amount of the purification waste liquid in the bag. The measurement result by the weigh scale 123 is output to the control device 14.

そして、血液浄化処理中、重量計123により浄化廃液バッグ52内の浄化廃液の液量がモニタリングされる。浄化廃液バッグ52内の浄化廃液の液量が所定の上限閾値以上になると、その液量増加情報が、通信部110から通信部111に送られる。浄化廃液の液量増加情報を受信した浄化液生成装置2では、チューブポンプ122が稼働され、浄化廃液バッグ52の浄化廃液が浄化廃液排出流路53、浄化廃液回収回路120を通じて浄化廃液タンク121に送られる。なお、このとき、チューブポンプ61は稼働し続けており、例えば血液浄化処理が中断されない。そして、浄化廃液バッグ52内の浄化廃液の液量が所定の下限閾値になったときに、当該液量下限情報が通信部110から通信部111に送られ、チューブポンプ122が停止される。これにより、血液浄化装置1から浄化液生成装置2への浄化廃液の回収が停止される。   During the blood purification process, the weight of the purified waste liquid in the purified waste liquid bag 52 is monitored by the weight scale 123. When the amount of the purified waste liquid in the purified waste liquid bag 52 becomes equal to or greater than a predetermined upper limit threshold value, the liquid amount increase information is sent from the communication unit 110 to the communication unit 111. In the purified liquid generating apparatus 2 that has received the information on the increase in the amount of the purified waste liquid, the tube pump 122 is operated, and the purified waste liquid in the purified waste liquid bag 52 is transferred to the purified waste liquid tank 121 through the purified waste liquid discharge channel 53 and the purified waste liquid recovery circuit 120. Sent. At this time, the tube pump 61 continues to operate, and for example, the blood purification process is not interrupted. When the amount of the purified waste liquid in the purified waste liquid bag 52 reaches a predetermined lower limit threshold, the lower limit liquid amount information is sent from the communication unit 110 to the communication unit 111, and the tube pump 122 is stopped. Thereby, collection | recovery of the purification waste liquid from the blood purification apparatus 1 to the purification liquid production | generation apparatus 2 is stopped.

かかる例によれば、浄化廃液バッグ52の浄化廃液の回収を自動で行うことができるので、浄化廃液バッグ50を交換する必要がなく、長時間の血液浄化治療における医師や看護師の負担を軽減できる。   According to such an example, since the purification waste liquid in the purification waste liquid bag 52 can be automatically collected, there is no need to replace the purification waste liquid bag 50, and the burden on doctors and nurses in the long-time blood purification treatment is reduced. it can.

また、浄化廃液回収回路120が、浄化液回路12における浄化廃液バッグ52とチューブポンプ61との間に接続されている。これにより、チューブポンプ61が浄化廃液排出回路53の浄化廃液バッグ52側への流れを規制するので、浄化廃液回収回路120を浄化廃液バッグ52に直接接続しなくても浄化廃液排出回路53に接続して、浄化廃液を好適に回収できる。この結果、従来から用いられていた構造の浄化廃液バッグ52をそのまま使用できる。また、チューブポンプ61と浄化廃液バッグ52との間が閉鎖系になっているので、チューブポンプ61を稼働させ、浄化廃液を血液浄化器10から排出しながら、浄化廃液バッグ52から浄化廃液を回収できる。したがって、血液浄化処理を中断せずに洗浄廃液の回収を行うことができるので、血液浄化治療の時間を短縮し、患者への負担も低減できる。なお、浄化廃液回収回路120は、必ずしも浄化液回路12における浄化廃液バッグ52とチューブポンプ61との間に接続されている必要はなく、浄化廃液バッグ52に直接接続されていてもよい。また、血液浄化処理を一旦中断して浄化廃液の回収を行ってもよい。   Further, the purified waste liquid recovery circuit 120 is connected between the purified waste liquid bag 52 and the tube pump 61 in the purified liquid circuit 12. As a result, the tube pump 61 regulates the flow of the purified waste liquid discharge circuit 53 toward the purified waste liquid bag 52, so that the purified waste liquid recovery circuit 120 can be connected to the purified waste liquid discharge circuit 53 without being directly connected to the purified waste liquid bag 52. Thus, the purification waste liquid can be suitably recovered. As a result, the purification waste liquid bag 52 having a structure conventionally used can be used as it is. Further, since the space between the tube pump 61 and the purification waste liquid bag 52 is a closed system, the purification waste liquid is collected from the purification waste liquid bag 52 while the tube pump 61 is operated and the purification waste liquid is discharged from the blood purifier 10. it can. Therefore, since the washing waste liquid can be collected without interrupting the blood purification treatment, the time for blood purification treatment can be shortened and the burden on the patient can be reduced. The purified waste liquid recovery circuit 120 does not necessarily need to be connected between the purified waste liquid bag 52 and the tube pump 61 in the purified liquid circuit 12, and may be directly connected to the purified waste liquid bag 52. Further, the blood purification treatment may be temporarily interrupted to collect the purification waste liquid.

また、本実施の形態によれば、浄化廃液バッグ52に重量計123を設け、通信手段4が、重量計123により検出された浄化廃液バッグ52の浄化廃液の液量に基づいて、浄化廃液バッグ52の浄化廃液が浄化液生成装置2に回収されるように、血液浄化装置1と浄化液生成装置2との間で情報の通信を行うので、浄化廃液液バッグ52からの浄化廃液の回収を適切なタイミングで好適に行うことができる。   In addition, according to the present embodiment, the purification waste liquid bag 52 is provided with the weight scale 123, and the communication means 4 is based on the amount of the purification waste liquid in the purification waste liquid bag 52 detected by the weight scale 123. Since the information is communicated between the blood purification device 1 and the purification liquid generation device 2 so that the purification waste liquid 52 is recovered by the purification liquid generation device 2, the recovery of the purification waste liquid from the purification waste liquid bag 52 is performed. It can be suitably performed at an appropriate timing.

なお、浄化液生成装置2は、浄化廃液タンク121を必ずしも備えている必要はなく、浄化廃液回収回路120から外部の排液ラインに接続できるようになっていてもよい。かかる場合、浄化液生成装置2に回収された浄化廃液は、外部の排液ラインに送られて排液される。   In addition, the purification liquid production | generation apparatus 2 does not necessarily need to be equipped with the purification waste liquid tank 121, and may be connected to the external drainage line from the purification waste liquid collection circuit 120. In such a case, the purified waste liquid collected by the purified liquid generator 2 is sent to an external drain line and drained.

以上の実施の形態において、例えば図3に示すように血液浄化システムAが、浄化液生成装置2から血液浄化装置1の補液バッグ70に補液を補充するために、補液回路13と浄化液生成装置2とを接続する補液補充回路130を有していてもよい。補液補充回路130は、例えば浄化液生成装置2に設けられた補液タンク131から補液回路13に接続されている。補液補充回路130は、補液バッグ70とチューブポンプ71との間に接続されている。補液補充回路130には、チューブポンプ132が設けられている。補液バッグ71には、バッグ内の補液の液量を検出する補液検出部としての重量計133が設けられている。重量計133による計測結果は、制御装置14に出力される。   In the above embodiment, for example, as shown in FIG. 3, the blood purification system A replenishes the replacement fluid to the replacement fluid bag 70 of the blood purification device 1 from the purification fluid generation device 2, and the replacement fluid circuit 13 and the purification fluid generation device. 2 may be provided. The replacement fluid replenishment circuit 130 is connected to the replacement fluid circuit 13 from a replacement fluid tank 131 provided in the purification fluid generator 2, for example. The replacement fluid replenishment circuit 130 is connected between the replacement fluid bag 70 and the tube pump 71. A tube pump 132 is provided in the replacement fluid replenishment circuit 130. The replacement fluid bag 71 is provided with a weight scale 133 as a replacement fluid detection unit that detects the amount of replacement fluid in the bag. The measurement result by the weight scale 133 is output to the control device 14.

そして、血液浄化処理中、重量計133により補液バッグ70内の補液の液量がモニタリングされる。補液バッグ70内の補液の液量が所定の下限閾値以下になると、その液量低下情報が、通信部110から通信部111側に送られる。補液の液量低下情報を受信した浄化液生成装置2では、チューブポンプ132が稼働され、補液タンク131の補液が補液補充回路130及び補液回路13を通じて補液バッグ70に送られる。なお、このとき、例えばチューブポンプ71は稼働し続けており、血液浄化処理が中断されない。そして、補液バッグ70内の補液の液量が所定の上限閾値になったときに、当該液量上限情報が通信部110から通信部111に送られ、チューブポンプ132が停止される。これにより、浄化液生成装置2から血液浄化装置1への補液の供給が停止され、補液バッグ70への補液の補充が停止する。   During the blood purification process, the weight of the replacement fluid in the replacement fluid bag 70 is monitored by the weight scale 133. When the amount of the replacement fluid in the replacement fluid bag 70 becomes equal to or less than a predetermined lower threshold value, the fluid amount decrease information is sent from the communication unit 110 to the communication unit 111 side. In the purifying fluid generating apparatus 2 that has received the fluid lowering information of the replacement fluid, the tube pump 132 is operated, and the replacement fluid in the replacement fluid tank 131 is sent to the replacement fluid bag 70 through the replacement fluid replacement circuit 130 and the replacement fluid circuit 13. At this time, for example, the tube pump 71 continues to operate, and the blood purification process is not interrupted. When the amount of the replacement fluid in the replacement fluid bag 70 reaches the predetermined upper limit threshold, the upper limit fluid amount information is sent from the communication unit 110 to the communication unit 111, and the tube pump 132 is stopped. As a result, the supply of the replacement fluid from the purification fluid generator 2 to the blood purification device 1 is stopped, and the replacement of the replacement fluid to the replacement fluid bag 70 is stopped.

かかる例によれば、補液バッグ70の補液の補充を自動で行うことができるので、補液バッグ70を交換する必要がなく、長時間の血液浄化治療における医師や看護師の負担を軽減できる。   According to this example, since the replacement fluid in the replacement fluid bag 70 can be automatically replenished, it is not necessary to replace the replacement fluid bag 70, and the burden on doctors and nurses in the long-time blood purification treatment can be reduced.

また、補液補充回路130は、補液回路13における補液バッグ70とチューブポンプ71との間に接続されている。これにより、チューブポンプ71が補液回路13の血液回路11側の流れを制限するので、補液補充回路130を補液バッグ70に直接接続しなくても補液回路13に接続して、補液を好適に補充できる。この結果、従来から用いられていた構造の補液バッグ70をそのまま使用できる。また、チューブポンプ71と補液バッグ70との間が閉鎖系になっているので、チューブポンプ71を稼働させ、補液を血液回路11に供給しながら、補液バッグ70に補液を補充できる。したがって、血液浄化処理を中断せずに補液を補充することができるので、血液浄化治療の時間を短縮し、患者への負担も低減できる。なお、補液補充回路130は、必ずしも補液回路13における補液バッグ70とチューブポンプ71との間に接続されている必要はなく、補液バッグ70に直接接続されていてもよい。また、血液浄化処理を一旦中断して補液の補充を行ってもよい。   The replacement fluid replenishment circuit 130 is connected between the replacement fluid bag 70 and the tube pump 71 in the replacement fluid circuit 13. As a result, the tube pump 71 restricts the flow of the replacement fluid circuit 13 on the blood circuit 11 side, so that the replacement fluid replenishment circuit 130 is connected directly to the replacement fluid circuit 13 without being connected directly to the replacement fluid bag 70, and the replacement fluid is preferably replenished. it can. As a result, the replacement bag 70 having a structure used conventionally can be used as it is. In addition, since the space between the tube pump 71 and the replacement fluid bag 70 is a closed system, the replacement fluid bag 70 can be replenished while the tube pump 71 is operated and the replacement fluid is supplied to the blood circuit 11. Therefore, since the replacement fluid can be replenished without interrupting the blood purification treatment, the time for blood purification treatment can be shortened and the burden on the patient can be reduced. Note that the replacement fluid replenishment circuit 130 is not necessarily connected between the replacement fluid bag 70 and the tube pump 71 in the replacement fluid circuit 13, and may be directly connected to the replacement fluid bag 70. Further, the blood purification process may be temporarily interrupted to replenish the replacement fluid.

本実施の形態によれば、補液バッグ70に重量計133を設け、通信手段4が、重量計133により検出された補液バッグ70の補液の液量に基づいて、浄化液生成装置2から補液バッグ70に補液が補充されるように、血液浄化装置1と浄化液生成装置2との間で通信を行うので、補液バッグ70への補液の補充を適切なタイミングで好適に行うことができる。   According to this embodiment, the replacement fluid bag 70 is provided with the weigh scale 133, and the communication means 4 sends the replacement fluid bag from the purified solution generator 2 based on the amount of the replacement fluid in the replacement fluid bag 70 detected by the weight meter 133. Since communication is performed between the blood purification apparatus 1 and the purification liquid generating apparatus 2 so that the replacement fluid is replenished to the replacement fluid 70, the replacement fluid can be suitably supplemented to the replacement fluid bag 70 at an appropriate timing.
