発明の詳細な説明Detailed description of the invention

本発明は、血液透析に用いられる透析液、とくに所定濃度の透析用原液を調製するための透析用粉末剤溶解装置及びこの透析用粉末剤溶解装置に用いられて好適な溶解槽キットに関する。 The present invention relates to a dialysate used for hemodialysis, particularly a dialysis powder solubilizer for preparing a dialysis stock solution having a predetermined concentration, and a dissolution tank kit suitable for use in the dialysis powder solubilizer.

従来の人工透析に用いられる血液浄化システムは、病院内に設置され、多人数用の血液透析を中央で集中管理できるようにした、いわゆるセントラル透析システムが知られている。このようなセントラル透析システムは、通常、透析液作製・供給装置から供給される透析液を、複数の透析装置に配管を介して導入し、各透析装置に設けられている血液浄化要素(例えば、ダイアライザ)を介して各患者の血液浄化治療を施すように構築されている。ここで、透析液、とくに所定濃度の透析用原液は、精製水製造装置、具体的には例えば逆浸透法精製水製造装置(RO装置)により製造された精製水を希釈水として、透析用粉末剤を溶解することにより調製される。透析用粉末剤は、透析用A粉末剤と透析用B粉末剤の二種類があり、透析用粉末剤溶解装置もそれぞれを専用で溶解する透析用A粉末剤溶解装置と、透析用B粉末剤溶解装置の二種類が必要である。 The blood purification system used for conventional artificial dialysis is known as a so-called central dialysis system, which is installed in a hospital and enables centralized management of hemodialysis for a large number of people. In such a central dialysis system, the dialysate usually supplied from the dialysate preparation / supply device is introduced into a plurality of dialysis machines via a pipe, and a blood purification element (for example, for example) provided in each dialysis machine is provided. It is constructed to administer blood purification treatment for each patient via a dialyzer). Here, the dialysate, particularly the stock solution for dialysis having a predetermined concentration, is a powder for dialysis using purified water produced by a purified water production apparatus, specifically, for example, a reverse osmosis method purified water production apparatus (RO apparatus) as diluted water. It is prepared by dissolving the agent. There are two types of dialysis powders, dialysis A powder and dialysis B powder, and the dialysis powder solubilizer also has a dialysis A powder solubilizer that exclusively dissolves each, and a dialysis B powder. Two types of melting equipment are required.

近年、通院による透析に代えて、またはこれとともに、在宅による透析が実施され始めている。在宅透析は、通院時間を削減することができるだけではなく、自分の生活スタイルに合わせて都合の良い時間に透析スケジュールを組むことができる等の利点がある。このような在宅透析に用いられる血液浄化装置は、畳1畳分程度の広さに設置することができ、各家庭に整備されている電源及び上下水道を用いることができる。 In recent years, home-based dialysis has begun to be performed in place of or in conjunction with outpatient dialysis. Home dialysis has the advantages of not only reducing hospital visits, but also allowing dialysis schedules to be set at convenient times according to one's lifestyle. The blood purification device used for such home dialysis can be installed in an area of about 1 tatami mat, and the power supply and water and sewage systems provided in each home can be used.

ところで、在宅透析においても、透析用A粉末剤溶解装置及び透析用B粉末剤溶解装置により、それぞれの溶解装置によって、透析用粉末剤と希釈水とを所定の混合比率で混合し、透析用粉末剤を希釈水で溶解することにより、所定濃度の透析用原液をバッチ方式で調製する必要がある。そして、バッチ方式で透析用原液を調製し、透析に使用した後は、透析用粉末剤溶解装置内において、透析用原液を調製するための溶解槽、この溶解槽から透析用原液を給水するための配管等を洗浄及び消毒する必要があるところ、このような洗浄及び消毒の煩は、在宅透析を推進する障害の一つとなっている。 By the way, also in home dialysis, the dialysis powder and the diluted water are mixed at a predetermined mixing ratio by the dialysis A powder dissolving device and the dialysis B powder dissolving device, respectively, and the dialysis powder is used. It is necessary to prepare a stock solution for dialysis having a predetermined concentration by a batch method by dissolving the agent in diluted water. Then, after preparing the stock solution for dialysis by the batch method and using it for dialysis, a dissolution tank for preparing the stock solution for dialysis and water for supplying the stock solution for dialysis from this dissolution tank in the powder solution for dialysis. Where it is necessary to clean and disinfect the pipes and the like, such troublesome cleaning and disinfection is one of the obstacles for promoting home dialysis.

The water leakage sensor 37 is 33 connected to the controller, and when the water leakage sensor 37 detects a water leakage, the controller 33 issues a warning to the effect that water leakage has occurred on the display panel, and controls the controller 33 to emit a warning sound by a separately provided buzzer or the like. Is preferable.

以上の透析用粉末剤溶解装置1は、典型的には自宅に設置される。また、溶解槽5,攪拌ファン9等が密封された溶解槽キット13が、透析患者ないしはその家族等が自宅に定期的に持ち込まれ、または自宅に配送される。患者又はその家族等により、溶解槽キット13のシール材15を破ることによって、消毒済みの攪拌ファン9が取り出される。電動モータ11等の駆動手段が上昇され、コネクタ17に攪拌ファン9が装着される。その後、溶解槽キット13のシール材15から溶解槽5を取り出し、溶解装置1の溶解槽設置部7に装着する。これにより、洗浄・消毒をすることなく、消毒済みの溶解槽5を得ることができる。 The above dialysis powder dissolving device 1 is typically installed at home. Further, the dissolution tank kit 13 in which the dissolution tank 5, the stirring fan 9, etc. are sealed is regularly brought to the home by the dialysis patient or his / her family, or delivered to the home. The disinfected stirring fan 9 is taken out by the patient or his / her family by breaking the sealing material 15 of the dissolution tank kit 13. The driving means such as the electric motor 11 is raised, and the stirring fan 9 is attached to the connector 17. After that, the dissolution tank 5 is taken out from the sealing material 15 of the dissolution tank kit 13 and attached to the dissolution tank installation portion 7 of the dissolution apparatus 1. As a result, the disinfected dissolution tank 5 can be obtained without cleaning and disinfecting.

溶解槽5内には、透析用粉末剤が投入され、給水部27から精製水が投入される。しかる後、攪拌ファン9が下降されて溶解槽5内に挿入され、電動モータ11等を駆動することにより、透析用粉末剤及び希釈水が混合され、粉末剤が溶解され、透析用原液が調製される。この間、ヒータ35が直接または間接的に透析用原液を加熱し、溶解を促進する。 A dialysis powder is charged into the dissolution tank 5, and purified water is charged from the water supply unit 27. After that, the stirring fan 9 is lowered and inserted into the dissolution tank 5, and by driving the electric motor 11 and the like, the dialysis powder and the diluted water are mixed, the powder is dissolved, and the dialysis stock solution is prepared. Will be done. During this time, the heater 35 directly or indirectly heats the dialysis stock solution to promote dissolution.

透析用原液が調製された後、ノズル穴29からノズルを挿入し、透析用原液は透析に供される。溶解槽5から透析用原液がなくなったとき、当該溶解槽5は溶解装置1から離脱され、廃棄される。この際、溶解槽5が可撓性を有していれば、力を加えることにより小さくすることができ、ゴミの嵩を減らすことができる。 After the dialysis stock solution is prepared, a nozzle is inserted through the nozzle hole 29, and the dialysis stock solution is subjected to dialysis. When the dialysis stock solution runs out from the dissolution tank 5, the dissolution tank 5 is separated from the dissolution device 1 and discarded. At this time, if the melting tank 5 has flexibility, it can be made smaller by applying force, and the bulk of dust can be reduced.

本発明は、あらゆる人工透析に用いられる透析用粉末剤溶解装置に適用可能であり、特に在宅透析に用いられて好適なものである。 The present invention is applicable to all dialysis powder dissolving devices used in artificial dialysis, and is particularly suitable for use in home dialysis.
