Description

本発明は透析システムに関し、詳しくは透析液を供給する透析液供給手段と、複数の透析用監視手段とを備えた透析システムに関する。   The present invention relates to a dialysis system, and more particularly, to a dialysis system including a dialysate supply means for supplying dialysate and a plurality of dialysis monitoring means.

従来、複数の患者に対して同時に人工透析治療を行うため、複数台の透析用監視手段を備えるとともに、各透析用監視手段に透析液を供給する透析液供給手段を備えた透析システムが用いられている。
各透析用監視手段において透析治療を行う時間は患者の体調や病状等によって異なるため、全ての透析用監視手段が一斉に透析治療を終了することはない。
そこで、一部の透析用監視手段で透析治療が終了した場合には、他の透析用監視手段で透析治療が行われていても、この透析用監視手段のみを洗浄して各透析用監視手段の稼働率を向上させるようにした透析システムが知られている。（特許文献１）
この特許文献１の透析システムでは、各透析用監視手段のそれぞれに、透析液供給手段を経ることなく洗浄液を供給する洗浄液供給源と、水を供給する水供給源とが接続され、透析用監視手段での透析治療が終了したら、該透析用監視手段に洗浄液を供給して洗浄し、さらに洗浄成分が残留しないように水洗により十分にすすぎ流すようになっている。
実公平６−２８１２８号公報 Conventionally, in order to simultaneously perform artificial dialysis treatment for a plurality of patients, a dialysis system including a plurality of dialysis monitoring means and a dialysis fluid supply means for supplying a dialysis fluid to each dialysis monitoring means has been used. ing.
Since the time for performing dialysis treatment in each dialysis monitoring means varies depending on the physical condition or medical condition of the patient, all the dialysis monitoring means do not end dialysis treatment at the same time.
Therefore, when dialysis treatment is completed by some dialysis monitoring means, even if dialysis treatment is being performed by other dialysis monitoring means, only this dialysis monitoring means is washed and each dialysis monitoring means is cleaned. There is known a dialysis system that improves the operation rate of the dialysis machine. (Patent Document 1)
In the dialysis system disclosed in Patent Document 1, a cleaning liquid supply source for supplying a cleaning liquid and a water supply source for supplying water are connected to each of the dialysis monitoring means without passing through the dialysis liquid supply means. When the dialysis treatment by the means is completed, the washing means is supplied to the dialysis monitoring means for washing, and the washing component is rinsed sufficiently so that no washing components remain.
No. 6-28128

しかしながら、上記特許文献１の透析システムの場合、上記水供給源から各透析用監視手段に個別に水を供給するための通路では、透析用監視手段が透析治療を行っている間は水が停滞するため、水が静置されることで配管内にバイオフィルム等の雑菌が発生して繁殖するおそれがあった。特に、上記水供給源が透析治療を実施する透析室とは別室に設置された場合、給水のための通路が長くなることから、雑菌の温床となるおそれがあった。
このような問題に鑑み、透析治療が終了した透析用監視手段ごとに洗浄および消毒を実施することが可能であって、各透析用監視手段を個別に洗浄するために設けた洗浄用の配管内で雑菌が発生し繁殖することを回避することが可能な透析システムを提供するものである。 However, in the case of the dialysis system disclosed in Patent Document 1, in the passage for supplying water individually from the water supply source to each dialysis monitoring means, water stagnates while the dialysis monitoring means is performing dialysis treatment. For this reason, there is a possibility that germs such as biofilms are generated in the piping and propagated by allowing the water to stand. In particular, when the water supply source is installed in a separate room from the dialysis room where dialysis treatment is performed, the passage for water supply becomes longer, which may cause a hotbed of various bacteria.
In view of such problems, it is possible to carry out cleaning and disinfection for each dialysis monitoring means for which dialysis treatment has been completed, and in the piping for cleaning provided to individually wash each dialysis monitoring means The present invention provides a dialysis system capable of avoiding the generation and propagation of various bacteria.

以下、図示実施例について説明すると、図１は本発明にかかる第１実施例の透析システム１を示し、この透析システム１は複数の患者に同時に透析治療を行うよう構成されている。

そして、本実施例の透析システム１において、上記透析液供給手段３、熱水供給手段４、浄水供給手段５は、透析用監視手段２により人工透析が実施される透析室とは別室に設置されており、上記透析液通路７および熱水通路９は建物の壁や天井裏、床下などの内部空間Ｗに敷設された配管として構成されている。 Hereinafter, the illustrated embodiment will be described. FIG. 1 shows a dialysis system 1 according to a first embodiment of the present invention. The dialysis system 1 is configured to simultaneously perform dialysis treatment on a plurality of patients.
The dialysis system 1 includes a plurality of dialysis monitoring means 2, a dialysis fluid supply means 3 for supplying a dialysis fluid to each dialysis monitoring means 2, and the dialysis treatment in each dialysis monitoring means 2 after completion of dialysis treatment. Hot water supply means 4 for supplying hot water for washing individually, purified water supply means 5 for supplying purified water to the dialysate supply means 3 and hot water supply means 4, and the dialysis monitor means 2 for dialysis A three-way valve 6 is provided as switching means for switching and supplying either liquid or hot water, and each operation is controlled by a control means (not shown).
The dialysate supply passage 3 is connected to a dialysate passage 7 through which the dialysate is circulated, and the dialysate passage 7 is connected to a dialysate branch passage 8 branched to each of the dialysis monitoring means 2. .
A hot water passage 9 through which hot water flows is connected to the hot water supply means 4, and the hot water passage 9 is branched toward each dialysis monitoring means 2 and provided in each dialysate branch passage 8. A hot water branch passage 10 connected to the three-way valve 6 is connected.
A purified water passage 12 for circulating purified water is connected to the purified water supply means 5, and the purified water passage 12 is branched and connected to each of the dialysate supply means 3 and the hot water supply means 4.
A drainage passage 13 is connected to each dialysis monitoring means 2, and the drainage passages 13 are joined and drained.
In the dialysis system 1 of this embodiment, the dialysate supply means 3, the hot water supply means 4, and the purified water supply means 5 are installed in a separate room from the dialysis room where the artificial dialysis is performed by the dialysis monitoring means 2. The dialysate passage 7 and the hot water passage 9 are configured as pipes laid in an internal space W such as a building wall, a ceiling, or under the floor.

上記透析液供給手段３は、透析液の原液としてのＡ原液を貯留するＡ原液タンク１４と、同じく透析液の原液としてのＢ原液を貯留するＢ原液タンク１５と、洗浄液の原液を貯留する洗浄液タンク１６とを備えている。
透析液供給手段３は上記Ａ原液およびＢ原液と上記浄水供給手段５からの浄水とを混合して透析液を調整し、この透析液を上記透析液通路７および透析液分岐通路８を介して各透析用監視手段２に供給するようになっている。
一方、全ての透析用監視手段２で透析治療が終了した際、透析液供給手段３は上記洗浄液の原液と浄水供給手段５からの浄水とを混合して洗浄液を調整し、この洗浄液を上記透析液通路７および透析液分岐通路８を介して全ての透析用監視手段２に供給し、一斉に透析システム１全体の洗浄を行うことができるようになっている。
上記透析液通路７の下流端には流量調整弁１７および開閉弁１８が設けられており、透析液通路７に透析液が供給されている間、上記開閉弁１８が開放されるとともに、流量調整弁１７が透析液の流量を絞ることで、少量の透析液の排液が常時行われるようになっている。
このように常時透析液を排出することで、透析液通路７内の透析液の流通が停滞することはなく、透析液通路７内での雑菌の発生を防止し、また透析液の成分が透析液通路７内に付着してしまうことを防止できる。 The dialysate supply means 3 includes an A stock solution tank 14 for storing an A stock solution as a dialysate stock solution, a B stock solution tank 15 for storing a B stock solution as a dialysate stock solution, and a cleaning solution for storing a stock solution of a cleaning solution. And a tank 16.
The dialysate supply means 3 mixes the A stock solution and B stock solution with the purified water from the purified water supply means 5 to adjust the dialysate, and this dialysate is passed through the dialysate passage 7 and the dialysate branch passage 8. The dialysis monitoring means 2 is supplied.
On the other hand, when dialysis treatment is completed in all the dialysis monitoring means 2, the dialysate supply means 3 mixes the stock solution of the washing liquid and the purified water from the purified water supply means 5 to adjust the washing liquid. The dialysis system 1 as a whole can be cleaned at the same time by supplying all the dialysis monitoring means 2 via the liquid passage 7 and the dialysate branch passage 8.
A flow rate adjusting valve 17 and an on-off valve 18 are provided at the downstream end of the dialysate passage 7. While the dialysate is supplied to the dialysate passage 7, the on-off valve 18 is opened and the flow rate is adjusted. A small amount of dialysate is always drained by the valve 17 reducing the flow rate of the dialysate.
By constantly discharging the dialysate in this way, the flow of the dialysate in the dialysate passage 7 is not stagnated, the generation of various bacteria in the dialysate passage 7 is prevented, and the components of the dialysate are dialyzed. It can prevent adhering in the liquid passage 7.

上記熱水供給手段４は、図２に示すように上記浄水供給手段５に接続された浄水通路１２から浄水が供給される浄水タンク２１と、この浄水タンク２１内の浄水を加熱する加熱手段２２と、浄水タンク２１内から熱水を送液する送液ポンプ２３とを備えている。
上記熱水通路９は図１に示すように末端同士が連通するループ配管となっており、一端が上記浄水タンク２１の下面に接続され、他端は浄水タンク２１の上部に接続されて、浄水タンク２１を含めて循環流路を形成している。
このため上記浄水タンク２１から送液ポンプ２３により送液された熱水は、熱水通路９を流通して再び浄水タンク２１に還流するようになっている。
透析用監視手段２の内部回路を消毒するには、８０℃以上の熱水を１０分間以上流通させることが要求され、このため加熱手段２２は浄水タンク２１内の浄水を熱水通路９内で８０℃以上を維持するように加熱するようになっている。
以上のように、浄水タンク２１内の浄水を加熱手段２２で加熱し、これをループ配管からなる熱水通路９で循環させることで、洗浄用の熱水の温度を所定温度範囲に維持するとともに、熱水を所要時にすぐに使用することができる。また、熱水を使用する場所が熱水供給手段４の設置場所から離れていても、必要な温度の熱水を供給することができる。
なお、熱水通路９から分岐した熱水分岐通路１０は、透析液供給手段２で透析治療を行っている間は、熱水の流通がなく温度の低い浄水が停滞した状態となるため、上記熱水分岐通路１０の全長は極力短くすることが望ましく、熱水分岐通路１０に停滞する浄水の量を極力少なくすることが望ましい。 The hot water supply means 4 includes a purified water tank 21 to which purified water is supplied from a purified water passage 12 connected to the purified water supply means 5 and a heating means 22 for heating the purified water in the purified water tank 21 as shown in FIG. And a liquid feed pump 23 for feeding hot water from the purified water tank 21.
As shown in FIG. 1, the hot water passage 9 is a loop pipe whose ends communicate with each other, one end is connected to the lower surface of the water purification tank 21, and the other end is connected to the upper part of the water purification tank 21. A circulation channel including the tank 21 is formed.
For this reason, the hot water sent from the water purification tank 21 by the liquid feed pump 23 flows through the hot water passage 9 and returns to the water purification tank 21 again.
In order to disinfect the internal circuit of the dialysis monitoring means 2, it is required that hot water of 80 ° C. or higher be circulated for 10 minutes or more. For this reason, the heating means 22 passes the purified water in the purified water tank 21 in the hot water passage 9. Heating is performed so as to maintain 80 ° C. or higher.
As described above, the purified water in the purified water tank 21 is heated by the heating means 22 and is circulated through the hot water passage 9 formed of a loop pipe, thereby maintaining the temperature of the hot water for cleaning in a predetermined temperature range. Hot water can be used immediately when needed. Moreover, even if the place where hot water is used is away from the place where the hot water supply means 4 is installed, hot water having a necessary temperature can be supplied.
Note that the hot water branch passage 10 branched from the hot water passage 9 is in a state where there is no circulation of hot water and the purified water having a low temperature is stagnant during the dialysis treatment by the dialysate supply means 2. The total length of the hot water branch passage 10 is desirably as short as possible, and it is desirable to reduce the amount of purified water stagnating in the hot water branch passage 10 as much as possible.

以下、上記構成を有する透析システム１の動作について説明する。
まず、透析液供給手段３においては、浄水供給手段５で清浄化された浄水が供給され、これにＡ原液、Ｂ原液が混合されて各透析用監視装置２で使用される透析液が連続的に調整される。
透析液供給手段３から供給される透析液は透析液通路７を流通し、各透析液分岐通路８を流通して上記透析用監視手段２に供給される。
このとき、透析液通路７の端部に設けた開閉弁１８は開放されており、また流量調整弁１７で流量を絞って常時少量ずつ透析液を排出させることで、透析液通路７内での透析液の停滞を防止するようになっている。
一方、熱水供給手段４では、浄水供給手段５から供給される浄水を上記浄水タンク２１で上記加熱手段２２によって加熱し、送液ポンプ２３により上記熱水通路９に供給している。
熱水通路９はループ配管となっていることから、流通する熱水は熱水通路９を循環して浄水タンク２１に還流し、再加熱されるようになっており、熱水通路９内の熱水の温度が低下せず、所定温度に保温されるようになっている。
その結果、熱水通路９内にバイオフィルム等の雑菌が繁殖することは防止され、また、透析治療が終了した透析用監視手段２に対して順次上記熱水分岐通路１０を介して直ちに熱水を供給することができる。
なお、透析治療を行う間、各三方弁６は透析液通路７と各透析用監視手段２とを接続するよう各透析液分岐通路８を連通させており、熱水分岐通路１０から透析液液分岐通路８への熱水の流入を阻止している。 Hereinafter, operation | movement of the dialysis system 1 which has the said structure is demonstrated.
First, in the dialysate supply means 3, the purified water purified by the purified water supply means 5 is supplied, and the A stock solution and the B stock solution are mixed with the dialysate used in each dialysis monitoring device 2 continuously. Adjusted to
The dialysate supplied from the dialysate supply means 3 flows through the dialysate passage 7 and is supplied to the dialysis monitoring means 2 through each dialysate branch passage 8.
At this time, the opening / closing valve 18 provided at the end of the dialysate passage 7 is opened, and the flow rate is reduced by the flow rate adjustment valve 17 so that the dialysate is always discharged little by little. The stagnation of dialysate is prevented.
On the other hand, in the hot water supply means 4, the purified water supplied from the purified water supply means 5 is heated by the heating means 22 in the purified water tank 21 and supplied to the hot water passage 9 by the liquid feed pump 23.
Since the hot water passage 9 is a loop pipe, the circulating hot water circulates in the hot water passage 9 and returns to the purified water tank 21 to be reheated. The temperature of the hot water does not decrease and is kept at a predetermined temperature.
As a result, it is possible to prevent bacteria such as biofilms from propagating in the hot water passage 9, and to the dialysis monitoring means 2 for which dialysis treatment is completed, immediately through the hot water branch passage 10, Can be supplied.
During the dialysis treatment, each three-way valve 6 communicates with each dialysate branch passage 8 so as to connect the dialysate passage 7 and each monitoring means 2 for dialysis. The inflow of hot water into the branch passage 8 is prevented.

透析治療が終了した透析用監視手段２ごとに洗浄および消毒を実施する場合は、透析治療を終了した透析用監視手段２に対応する三方弁６を切り換えて、熱水分岐通路１０を透析液分岐通路８へ接続する。
これにより、対応する透析用監視手段２と透析液通路７との連通は遮断され、熱水通路９の熱水が熱水分岐通路１０を介して透析用監視手段２に供給され、透析用監視手段２の内部回路を熱水が流通して、透析用監視手段２の洗浄および消毒が行われる。そして、透析用監視手段２の内部回路内を流通した熱水は排液通路１３を介して排出される。
透析用監視手段２の内部回路の洗浄が終了すると、三方弁６を切り換えて透析液分岐通路８を介して透析液通路７の透析液を透析用監視手段２に供給し、再び該透析用監視手段２において透析治療を行うことが可能となる。
そして全ての透析用監視手段２で透析治療が終了すると、上記透析液供給手段３は洗浄液を調整し、全ての透析用監視手段２を対象に洗浄液を用いた洗浄および消毒を行う。 When cleaning and disinfection are performed for each dialysis monitoring means 2 for which dialysis treatment has been completed, the three-way valve 6 corresponding to the dialysis monitoring means 2 for which dialysis treatment has been completed is switched to branch the hot water branch passage 10 to the dialysate branch. Connect to passage 8.
As a result, the communication between the corresponding dialysis monitoring means 2 and the dialysate passage 7 is cut off, and the hot water in the hot water passage 9 is supplied to the dialysis monitoring means 2 via the hot water branch passage 10. Hot water flows through the internal circuit of the means 2 so that the dialysis monitoring means 2 is cleaned and disinfected. Then, the hot water flowing through the internal circuit of the dialysis monitoring means 2 is discharged through the drainage passage 13.
When the cleaning of the internal circuit of the dialysis monitoring means 2 is completed, the three-way valve 6 is switched to supply the dialysis fluid in the dialysis fluid passage 7 to the dialysis monitoring means 2 via the dialysate branch passage 8 and again for the dialysis monitoring. The dialysis treatment can be performed in the means 2.
When the dialysis treatment is completed in all the dialysis monitoring means 2, the dialysis fluid supply means 3 adjusts the cleaning liquid, and performs cleaning and disinfection using the cleaning liquid for all the dialysis monitoring means 2.

なお、本実施例における透析用監視手段１０２、透析液供給手段１０３、熱水供給手段１０４の構成は上記第１実施例のものと同一の構成を有しており、詳細な説明は省略する。 FIG. 3 shows a dialysis system 101 according to a second embodiment of the present invention.

The configuration of the dialysis monitoring means 102, dialysate supply means 103, and hot water supply means 104 in this embodiment is the same as that of the first embodiment, and a detailed description thereof is omitted.

本実施例の透析液通路１０７は、透析用監視手段１０２の台数に応じた数に分岐され、分岐した各透析液通路１０７からそれぞれ１本ずつ透析液分岐通路１０８が分岐されて、各透析用監視手段１０２に接続されている。
