By the way, those that can prepare and supply dialysate for each blood purifier (ie each dialysis patient) are called personal dialysis machines. The term “dialysis treatment system” is used as a generic term.

  By the way, it is necessary to wash and disinfect the flow path through which clean water and dialysate flow in the dialysis treatment system from the viewpoint of hygiene maintenance. For example, chlorine-based disinfection such as sodium hypochlorite is used as the disinfectant. A cleaning agent is used. In order to perform disinfection after washing with the washing water, conventionally, a disinfectant solution is supplied to the dialysate supply device, and the dialysate supply device flows from the dialysate supply device to a dialysis monitoring device ( For example, see Patent Document 1).

That is, by distributing the disinfectant solution along the flow path of clean water or dialysate in the dialysate supply device, the dialysis monitoring device, and the piping connecting them, the flow path of the dialysate and the like (specifically In this case, the inner wall of the flow path was disinfected, thereby disinfecting the entire flow path of clean water and dialysate.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The dialysis treatment system according to the first embodiment is capable of preparing a dialysis stock solution (A stock solution and B stock solution) or preparing a dialysis solution (A solution and B solution). As shown in FIG. The apparatus is mainly composed of a clean water generating device 1, a dialysate supply device 6 (a dialysate supply device for a large number of people), a supply device 2 comprising a dissolving device 7 and a personal dialyzer 8, and a control means 9. .

  The clean water generating apparatus 1 includes a module 3 (purification filter) having a filter membrane and the like, a storage tank 4 having a predetermined capacity, and a heater 5 (heating means) disposed in the storage tank 4. 3, the raw water introduced from the supply path L1 is passed through and filtered, so that clean water (RO water) can be generated. The obtained clean water reaches the storage tank 4 through the flow path L2, and is stored in a predetermined amount in the storage tank 4.

  From the storage tank 4, the 1st circulation flow path which consists of flow paths L3 and L4 is extended, and the pump P1 is connected to the upstream of the flow path L3. As a result, the clean water stored in the storage tank 4 can be circulated through the first circulation channel while being heated by the heater 5. For example, hot water (hot water disinfectant) of 80 ° C. or higher can be generated. it can. That is, in this embodiment, hot water is used as the hot water disinfectant. In addition, the 1st circulation flow path and the heater 5 comprise the hot water disinfection liquid production | generation means of this invention.

  From the flow path L3 constituting the first circulation flow path, the clean water generated by the clean water generating apparatus 1 is supplied to each supplied apparatus 2 (the dialysate supply apparatus 6, the dissolving apparatus 7 and the personal dialysis apparatus 8). A water supply path L5 for supply is connected. However, at the time of dialysis treatment, clean water is supplied from the water supply path L5 to each supply device 2 while circulating through the first circulation flow path, and at the time of disinfection, the heater 5 circulates through the first circulation flow path. The heated hot water disinfectant is supplied to each supply target device 2 from the water supply path L5. The clean water generated by the clean water generating device 1 is used when preparing the dialysate in the supply target device 2 or preparing a dialysis stock solution, or cleaning the flow path of each supply target device 2. Also used as water.

  The dissolving device 7 includes a clean water flow path L9 communicating with the water supply path L5, a water supply path L5, an electromagnetic valve V for opening and closing the flow path L9, and a flow path L10 for dialysis undiluted solution, and the supplied clean water A dialysis stock solution having a predetermined concentration is prepared by dissolving a powdery dialysis drug. The stock solution for dialysis produced by the dissolving device 7 is supplied to the dialysate supply device 6, where it is further diluted with clean water to obtain a dialysate having a predetermined concentration. In the figure, L5a indicates a waste liquid line branched from the water supply path L5 in the vicinity of the dissolving device 7, and an electromagnetic valve V is connected to the middle of the waste liquid line L5a.

  The personal dialysis machine 8 discharges the dialysate containing waste products and the like discharged from the flow path L11 communicating with the water supply path L5, the electromagnetic valve V that opens and closes the flow path L11, and the dialyzer K (blood purifier). The dialysis fluid is prepared by mixing a stock solution for dialysis having a predetermined concentration with the supplied clean water, and then supplying the dialysis fluid to the dialyzer K. The dialyzer K is connected to a blood circuit (not shown), and can dialyze the blood of the patient flowing through the blood circuit.

  The dialysate supply device 2 can prepare a dialysate having a predetermined concentration using the clean water supplied from the clean water generating device 1, and measures the amount of clean water supplied from the water supply path L5. The water metering cylinder 6a to be introduced while having a relatively large capacity storage tank 6b. Two mixing chambers (not shown) are connected in series in the flow path between the water metering cylinder 6a and the storage tank 6b, and dialysis stock solutions (B stock solution and A stock solution) are introduced from each of them and mixed with clean water. The dialysate having a predetermined concentration can be prepared.

  Further, a flow path L6 extends from the storage tank 6b, and as shown in FIG. 2, the flow path L6 is connected to a plurality of dialysis monitoring devices 10 via the flow path L8. On the other hand, this flow path L6 constitutes a second circulation flow path together with the flow path L7, so that the hot water disinfecting liquid sent from the dialysate supply device 6 can be circulated in the second circulation flow path. It is configured. In addition, the code | symbol G in the figure has shown the non-return valve.

  Furthermore, a pump P3 and a heater 11 as a heat retaining means are connected to the flow path L7 constituting the second circulation flow path, and a waste liquid path L7a extending from between the heater 11 and the check valve G is connected to the flow path L7. Is connected to an electromagnetic valve V. During the dialysis treatment, the pump P3 is operated, so that the dialysate sent from the dialysate supply device 6 reaches the dialysis monitors 10 from the flow path L6 while circulating.

  Therefore, since the second circulation channel includes a channel (specifically, the channel L6) through which the dialysate flows during dialysis treatment, the channel is used in the circulation process of the hot water disinfectant during disinfection. Can be sterilized and disinfected. Further, the hot water disinfectant is heated by the heater 11 while being sterilized by circulating through the second circulation channel, and is configured to be maintained at a predetermined temperature (about 80 ° C. or higher). Thereby, it can avoid that the hot water as a hot-water disinfection liquid becomes low temperature with the passage of time, and a disinfection action (sanitization effect) will deteriorate.

  A plurality of (5 in the present embodiment) monitoring apparatuses 10 for dialysis are installed in accordance with dialyzers K (blood purifiers) for performing dialysis treatment on patients, and dialysate prepared by the dialysate supply means 2 is used. The dialysate K is supplied to each dialyzer K. The dialysate sent through the flow path L8 is supplied to the dialyzer K, and the dialysate K containing the wastes and the like is removed to the outside by the purification action of the dialyzer K. It is configured to be discharged.

  The control means 9 is electrically connected to the clean water generating device 1 and each supplied device 2 to detect the operating state of these devices, and at the time of disinfection with the hot water disinfectant, the operation of the clean water generating device 1 is performed. And information (control signal or the like) for linking the operation of each supplied apparatus 2 with each other. Thereby, the timing which transfers to the washing | cleaning process by a clean water from a dialysis treatment and the disinfection process by a hot-water disinfection liquid can be controlled, and automation of a system can be aimed at.

Next, a method for disinfecting the dialysis treatment system will be described.
When all the dialysis treatments of the plurality of dialysis monitoring devices 10, the dialysate preparation operation by the dialysate supply device 6, the dissolution operation by the dissolution device 7, and the dialysis treatment by the personal dialysis device 8 are completed, the end signal is a control means. 9, it is recognized that the transition to the disinfection operation is possible, and a control signal is transmitted from the control means 9 to the clean water generating apparatus 1 to instruct the generation of the hot water disinfectant.

  When the clean water generator 1 receives the control signal, the pump P1 is driven to circulate the clean water in the storage tank 4 in the first circulation channel, and the heater 5 is operated to heat the circulated clean water. By using hot water, a hot water disinfectant is produced. At this time, since the dialysate supply device 6, the dissolving device 7 and the personal dialyzer 8 are stopped, the circulating clean water and hot water disinfectant do not flow to these devices.

  When a sensor (not shown) detects that the hot water disinfectant circulating through the first circulation channel has reached a predetermined temperature (for example, 80 ° C.) or higher, a signal is transmitted to the control means 9. Each supplied device 2 starts the disinfection operation (or the electromagnetic valve V is opened) when receiving the signal, and the hot water disinfectant is supplied to each supplied device 2 via the water supply path L5. .

  In the dialysate supply device 6, after the water metering cylinder 6a is driven to store the hot water disinfectant in the storage tank 6b, the hot water disinfectant flows in the upper part of the storage tank 6b through an overflow line (not shown) or the like. In addition to being sterilized, it is discharged from the flow path L6. Thereby, the flow path through which the clean water and the dialysate flow in the dialysate supply device 6 can be sterilized by the heat of the hot water disinfectant. Similarly, in the personal dialysis machine 8, by opening the valve V, the hot water disinfectant flows through the flow path through which clean water or dialysate flows, such as the flow path L11 and the discharge path L12. It can be sterilized by disinfection with the heat of the disinfectant.

  However, in an apparatus having a flow path with poor heat resistance inside (dissolution apparatus 7 in the present embodiment), the electromagnetic valve V of the flow path L9 is closed and the electromagnetic valve V of the waste liquid path L5a is opened, and the waste liquid path L5a. The hot water disinfectant is discharged from the outside and is not introduced into the dissolving device 7. Thus, even if the hot water disinfectant is discharged from the waste liquid path L5a, the water supply path L5 up to the junction of the waste liquid path L5a can be disinfected. If there is no flow path with poor heat resistance in the dissolution apparatus 7, the hot water disinfectant is passed through the flow path in the dissolution apparatus 7 (the flow path through which clean water and the dialysis stock solution circulate) to disinfect. It is preferable to configure as described above.

  On the other hand, in the disinfection of the flow path L6 that communicates the dialysate supply device 6 and the dialysis monitoring device 10, the dialysis monitoring device 10 is stopped to block the inflow from the flow path L8 and in the flow path L7. The pump P3 is driven with the electromagnetic valve V opened. As a result, the hot water disinfectant in the storage tank 6b reaches the flow path L6, flows through the flow path L7, and is then discharged to the outside from the waste liquid path L7a. When the hot water disinfectant in the storage tank 6b reaches the flow path L6 and the flow path L7, and the flow paths are replaced from the washing water to the hot water disinfectant, the electromagnetic valve V is closed to form the second circulation flow path. .

  Then, the heater 11 is operated while driving the pump P3, and the hot water disinfectant is circulated in the second circulation channel. In the circulation process of the hot water disinfectant, the flow path (flow path L6) through which the dialysate flows during dialysis treatment is disinfected, and the hot water disinfectant is heated by the heater 11 to a predetermined temperature (about 80 ° C. or higher). ). When the disinfection of the flow path L6 as described above is completed, the dialysis monitoring apparatus 10 is driven, and the hot water disinfectant is caused to flow into the dialysis monitoring apparatus 10 from the flow path L8. As a result, the flow path through which the dialysate flows in the dialysis monitoring apparatus 10 can be sterilized.

  According to the above embodiment, since disinfection with hot water disinfectant, even if the hot water disinfectant remains in the flow path, there is no effect on the human body, and safety during dialysis treatment can be improved. Since the hot water disinfecting liquid is generated by the clean water generating apparatus 1, the hot water disinfecting liquid is sent to the supplied apparatus 2 through the water supply path L5, and the supplied apparatus 2 is disinfected, so that the disinfection operation can be automated. Can be easy.

  Moreover, since the hot water disinfection liquid is generated by heating the heater 5 while circulating the clean water generated by the clean water generator 1 in the first circulation flow path, the hot water disinfection liquid can be generated efficiently. Can do. Further, the control means 9 detects each operation state of the clean water generating device 1 and the supplied device 2, and at the time of disinfection with the hot water disinfectant, the operation of the clean water generating device 1 and the operation of the supplied device 2 are performed. Since information to be linked is transmitted and received, an efficient disinfection operation can be performed.

  In particular, according to the present embodiment, the hot water disinfecting solution generated by the clean water generating device 1 is sequentially sent to the dialysate supplying device 6 and the dialysis monitoring device 10, so that the amount of use of the hot water disinfecting solution is further suppressed. However, the disinfection operation can be performed more efficiently. However, the hot water disinfectant is circulated in the second circulation passage between the dialysate supply device 6 and the dialysis monitoring device 10, and the circulating hot water disinfectant is heated by the heater 11 to be predetermined. Since the temperature is maintained (about 80 ° C. or higher), it is possible to avoid the deterioration of the disinfection action due to a decrease in the temperature of the hot water disinfectant sent to the dialysis monitoring device 10.

Next, a dialysis treatment central system according to a second embodiment of the present invention will be described.
As in the first embodiment, this dialysis treatment system is capable of preparing a dialysis stock solution (A stock solution and B stock solution) or preparing a dialysis solution (A solution and B solution), as shown in FIG. In addition, a clean water generating apparatus 1 having citric acid supply means, a dialysate supply apparatus 6 (dialysis liquid supply apparatus for a large number of people), a dissolving apparatus 7 and a personal dialyzer 8 and a supplied apparatus 2 and control means 9 is mainly composed.

Thereby, citric acid is mixed in the process in which the clean water generated in the module 3 and accommodated in the storage tank 4 circulates in the second circulation channel.

  That is, when the control means 9 instructs the clean water generator 1 to generate the hot water disinfectant, the pump P1 is driven and the clean water in the storage tank 4 circulates through the first circulation flow path. The citric acid is mixed and heated to a predetermined temperature (about 80 ° C. or higher) by the heater 5 to generate hot citric acid water as a hot water disinfectant. Such citric acid hot water is supplied to each supply target device 2 as in the first embodiment, and passes through the flow paths (flow paths through which clean water, dialysate, dialysis stock solution, etc. pass). It will be sterilized and disinfected.

  In this way, citric acid is supplied to the circulating clean water to generate citric acid hot water as the hot water disinfectant, so the calcium carbonate is removed in addition to disinfecting the flow path with a single type of disinfectant. In addition, there is no risk of residual substances that affect the human body such as sodium hypochlorite, and the safety during dialysis treatment can be further improved. In addition, for the disinfection by the heat of citric acid hot water (disinfection by hot water as in the first embodiment), it is detected whether or not the disinfection liquid is flowing by controlling the temperature of the liquid flowing in the flow path. It can be performed.

  As mentioned above, although this embodiment was described, this invention is not limited to these, For example, using the clean water as the to-be-supplied apparatus 2 to which the clean water produced | generated by the clean water production | generation apparatus 1 is supplied.

You may comprise so that driving | operation of each apparatus may be cooperated. In particular, in the second embodiment, the citric acid supply means (pump P2, introduction path L13) is connected to the first circulation flow path (specifically, downstream of the flow path L4). (For example, you may connect to the flow path L2 or L3 or the storage tank 4 etc.). In addition, it is good also as only the flow path 6 which can eliminate a 2nd circulation flow path and can send dialysate to the flow path L8.

  Furthermore, disinfection with a hot water disinfectant such as hot water or hot citric acid may be used in combination with conventional disinfection with sodium hypochlorite or the like. For example, disinfection with a hot water disinfectant is usually used. And may be disinfected with sodium hypochlorite or the like periodically (every few months, etc.).
