Description

The present invention relates to a dissolution device for dissolving a dialysis powder to obtain a dialysis stock solution.

The dialysate used for the treatment of patients with renal failure in hospitals is generally classified into bicarbonate type and acetic acid type, and among them, the bicarbonate type dialysate does not contain sodium bicarbonate (hereinafter, It is prepared by mixing water with two types of agents, agent A) and sodium bicarbonate (hereinafter referred to as agent B). In recent years, from the viewpoint of improving transportability, attempts have been made to dissolve these powders A and B (hereinafter referred to as "dialysis powder") immediately before dialysis treatment or during dialysis treatment.

That is, the undiluted solution prepared by dissolving the dialysis powder (the A undiluted solution in which the A agent is dissolved or the B undiluted solution in which the B agent is dissolved) is preferably used for treatment as soon as possible after the dissolution from the viewpoint of cleanliness. In particular, since the components of the B stock solution may change over time, it is not preferable to leave the B stock solution for a long time. Therefore, it is necessary to prepare the A stock solution and the B stock solution immediately before the dialysis treatment. Furthermore, if the A stock solution or the B stock solution is insufficient during dialysis treatment, it is necessary to additionally prepare each stock solution.

As described above, since a dissolution operation is required for each dialysis treatment, various dissolution devices for dissolution have been conventionally proposed. For example, Patent Documents 1 to 3 disclose a dissolution apparatus having two dissolution tanks, and with such a configuration, a dialysate stock solution is sent from one dissolution tank to the dialysis apparatus side during dialysis treatment. While the dialysis powder is added to the other dissolution tank, the dialysis powder can be additionally dissolved.

As shown in FIG. 5, the water supply line L1 is provided with a valve V1 composed of a solenoid valve or the like, and by opening the valve V1, water can be supplied into the first dissolution tank 2. There is. Then, after supplying a predetermined amount of water from the water supply source to the first dissolution tank 2 and accommodating it, a predetermined amount (specified amount) of the dialysis powder is first dissolved with respect to the amount of the water. By putting it in the tank 2, a predetermined amount and a predetermined concentration of undiluted solution for dialysis can be obtained.

Valves V2, V3, and V4 made of solenoid valves and the like are arranged in the connection line L4, and by opening these valves V2, V3, and V4, the liquid in the first dissolution tank 2 is brought into the open state. 2 It is possible to transfer it into the melting tank 3. The second melting tank 3 according to the present embodiment is a tank having a relatively smaller capacity than the first melting tank 2, and is connected to the first melting tank 2 by an overflow line L5.

Further, in the first dissolution tank 2, in addition to the water supply line L1 and the connection line L4, the connection line L2 is connected. One end of the connection line L2 is connected to the first melting tank 2, and the other end is connected to the connection portion b (position between the valve V2 and the valve V3) in the connection line L4. Further, the base end of the liquid feeding line L3 is connected to the connection portion a (position between the arrangement portion of the pump P1 and the connection portion b) in the connection line L2. The liquid feeding line L3 is provided with a pump P2 and a valve V5 made of a solenoid valve or the like. A connection line L6 in which a valve V6 composed of a solenoid valve or the like is arranged is connected between the liquid feeding line L3 and the connection line L4.

In the liquid feeding line L3, a pump P2 is arranged in the middle thereof, and the tip thereof is connected to a dialysate supply device B (see FIG. 4), and a dialysate undiluted solution prepared by the dissolution device 1 is supplied to the dialysate. It is said that the liquid can be sent to the device B. The dialysate supply device B prepares a dialysate by diluting the undiluted solution for dialysis sent from the dissolution device 1 to a predetermined concentration, and as shown in FIG. 4, a plurality of dialysate devices A via a pipe. It is connected to the. Therefore, the stock solution for dialysis produced by the dissolution device 1 is made into a dialysate having a predetermined concentration by the dialysate supply device B, and is sent to each dialysis device A for dialysis treatment.

The liquid level detecting means 9 includes a sensor arranged in the first dissolution tank 2, and can continuously and in real time detect the liquid level of the undiluted solution for dialysis contained in the first dissolution tank 2. is there. The liquid level detecting means 9 according to the present embodiment is composed of a magnetostrictive linear displacement sensor having a floating means that floats on the liquid surface of the liquid contained in the first dissolution tank 2 and can move up and down. It is possible to detect the liquid level (that is, the liquid level) by continuously and in real time detecting the position of the means.

The liquid level detecting means 9 may be capable of continuously and in real time detecting the liquid level of the stock solution for dialysis (which may be supplied water or solution) contained in the first dissolution tank 2. For example, it may be either a contact type or a non-contact type, and may be configured by a magnetostrictive linear displacement sensor by a floating means as in the present embodiment, or an ultrasonic sensor or the like. Further, in the present embodiment, the liquid level detecting means 9 is arranged only in the first dissolution tank 2, but it may be arranged in the second dissolution tank 3 together with the first dissolution tank 2. ..

Further, the liquid level detecting means 9 is electrically connected to the notifying means 10.

It is composed of lights and the like. That is, when the liquid level detected by the liquid level detecting means 9 is lower than a predetermined height and it is predicted that the undiluted solution for dialysis will be insufficient, the notification means 10 notifies the additional powder for dialysis. An undiluted solution for dialysis can be additionally prepared by adding it to a worker such as a medical worker and additionally dissolving it.

Next, the operation for melting by the melting device 1 according to the present embodiment will be described.
First, before the dialysis treatment (the night before the treatment, etc.), as shown in FIG. 6, a predetermined amount (the number of prepared dissolution bags) of the dialysis powder is charged into the second dissolution tank 3 and stored. Then, by closing the valves V3 to V6 while keeping the valves V1 and V2 open, water is supplied from the water supply source to the first dissolution tank 2, and the supplied water is circulated by driving the pump P1. Let me.

After that, as shown in FIG. 7, the valves V1, V3, and V4 are opened and the valves V2, V5, and V6 are closed, and the water supply from the water supply source and the driving of the pump P1 are continuously performed. The water in the first melting tank 2 is sent to the second melting tank 3. As a result, water is sent to the dialysis powder prepared in the second dissolution tank 3 in advance and dissolved, and the dissolution solution (the solution in the process of becoming the dialysis stock solution) is first passed through the overflow line L5. It will be sent to the melting tank 2.

Then, when a predetermined amount of water is supplied, as shown in FIG. 8, the valves V3 and V4 are opened and the valves V1, V2, V5 and V6 are closed, and the water supply from the water supply source is stopped. By continuously driving the pump P1, the stock solution for dialysis is circulated between the first dissolution tank 2 and the second dissolution tank 3. As a result, the prepared dialysis stock solution can be agitated, and a dialysis stock solution having a uniform concentration can be obtained.

As described above, in the state where the stock solution for dialysis is contained in each of the first dissolution tank 2 and the second dissolution tank 3, as shown in FIG. 9, the valves V1 to V4 and V6 are closed while the valves V5 are opened. By driving the pump P1 and the pump P2 in this state, the undiluted solution for dialysis in the first dissolution tank 2 can be supplied to the dialysate supply device B via the solution feeding line L3, and the dialysate having a predetermined concentration can be supplied. Can be supplied to each dialysis apparatus A to perform dialysis treatment.

After that, when the liquid level of the stock solution for dialysis in the first dissolution tank 2 reaches a predetermined height by the liquid level detecting means 9, the notification means 10 notifies the additional charging. In this case, as shown in FIG. 10, the valves V1, V2, V4, and V6 are opened and the valves V3 and V5 are closed to supply water from the water supply source, while the pump P2 is continuously driven. By doing so, the stock solution for dialysis in the second dissolution tank 3 is sent to the dialysate supply device B instead of the first dissolution tank 2.

Therefore, a predetermined amount (the number of additional charging bags) of the additional dialysis powder can be charged into the first dissolution tank 2, and the charged dialysis powder is dissolved by water supply from the water supply source. It will be. By driving the pump P1, the solution in the process of becoming a stock solution for dialysis can be circulated. As a result, the stock solution for dialysis is continuously sent from the second dissolution tank 3 instead of the first dissolution tank 2, and an additional powder for dialysis can be added and dissolved in the first dissolution tank 2. it can.

Then, when a predetermined amount of water is supplied, as shown in FIG. 11, the valves V2, V4, and V6 are opened and the valves V1, V3, and V5 are closed, and the water supply from the water supply source is stopped. By continuously driving the pumps P1 and P2, the undiluted solution for dialysis is continuously sent from the second dissolution tank 3, and the undiluted solution for dialysis in the first dissolution tank 2 is circulated and stirred. A dialysis stock solution having a uniform concentration can be obtained.

In the state where the undiluted solution for dialysis is contained in the first dissolution tank 2 as described above, as shown in FIG. 12, the valves V1 and V6 are closed while the valves V2 to V5 are open, and the pumps P1 and P2 are closed. By driving, the undiluted solution for dialysis in the first dissolution tank 2 can be supplied to the dialysate supply device B via the solution supply line L3, and the dialysate having a predetermined concentration is supplied to each dialysate device A. Can be used for dialysis treatment. At this time, a part of the dialysis stock solution in the first dissolution tank 2 is transferred to the second dissolution tank 3, and the dialysis stock solution is sent to a state of overflowing at the overflow line L5.

After that, as shown in FIG. 9, the valves V1 to V4 and V6 are closed while the valves V5 are open, and the pumps P1 and P2 are driven to drive the first dissolution tank 2 via the liquid feed line L3. The stock solution for dialysis can be sent to the dialysate supply device B, and the dialysate having a predetermined concentration can be supplied to each dialysis device A to perform dialysis treatment. As a result, the stock solution for dialysis additionally dissolved in the first dissolution tank 2 can be supplied to the dialysate supply device B, so that the dialysis treatment by each dialysis device A can be continuously performed.

As described above, the dissolving apparatus 1 according to the present embodiment sends the dialysis stock solutions of the first dissolving tank 2 and the second dissolving tank 3 to the plurality of dialysis apparatus A sides for performing the dialysis treatment on the patient during the dialysis treatment. Along with the liquid, an additional dialysis powder can be added into a predetermined amount (in this embodiment, a bag unit (the number of bags) containing the dialysis powder) to dissolve the dialysis powder, which is a so-called batch. It is supposed to consist of a melting device called a formula.

Here, as shown in FIG. 5, the housing portion of the melting device 1 according to the present embodiment includes an input means 4, a storage means 5, a setting means 6, a prediction means 7, and a display means 8. It is configured to have. The input means 4 is composed of an operation switch, a touch panel, or the like that can be input-operated by the operator, and in the present embodiment, the total amount of the dialysis powder required for dialysis treatment can be input. ing.

The display means 8 is composed of a liquid crystal monitor or the like capable of performing various displays related to the melting operation, and in the present embodiment, the display means 8 is composed of a touch panel that also serves as the input means 4 and the display means 8. In addition to the touch panel that also serves as the input means 4 and the display means 8, the input means 4 and the display means 8 may be separately provided.

The storage means 5 can store the timing of adding the additional dialysis powder during the past dialysis treatment as the actual input timing, and in the present embodiment, it corresponds to the treatment schedule of the patient in a medical facility such as a hospital. It is configured to store the actual input timing for each specific treatment day (specifically, for each day). That is, since dialysis patients usually receive dialysis treatment on fixed days of the week (for example, Monday, Wednesday, and Friday), medical staff also perform fixed work on each day of the week. Therefore, the consumption amount and flow rate of the dialysis stock solution and dialysate are almost constant depending on the day of the week (each specific treatment day corresponding to the patient's treatment schedule). Therefore, if the actual input timing is memorized for each day of the week, additional dialysis powder is added. It is possible to accurately predict the timing of adding the agent.

The setting means 6 adds the number of additional dialysis powders to be added and the addition of the dialysis powders to be added at each additional addition timing based on the total amount of the dialysis powders input by the input means 4. The amount and can be set automatically. For example, in the display means 8, when a specific day of the week (for example, Monday) is selected on the menu screen as shown in FIG. 13 and the total amount of dialysis powder required for that day is input, the prepared dissolution amount (before treatment) is input. The number of bags to be dissolved in advance), the number of times the dialysis powder is added (the number of additions), and the amount of the dialysis powder to be added at each additional timing (the number of bags at the time of addition) are automatically assigned. It is configured to be set and displayed by the display means 8 as shown in FIG.

The prediction means 7 predicts the timing of adding the additional dialysis powder during the dialysis treatment to be performed as the predicted input timing based on the actual input timing (time in the present embodiment) stored in the storage means 5. It is possible. Specifically, among the actual input timings stored in the storage means 5, the latest input timing (if the day of dialysis treatment is from now on is Monday, the one of last Monday) is set as the predicted input timing, and the day after that. On each dialysis treatment day, the actual input timing is sequentially overwritten and saved, and the actual input timing stored in the storage means 5 is updated (stored information is updated) for each dialysis treatment day.

Further, the method of predicting the predicted input timing by the predicting means 7 is not limited to the above, for example, a plurality of actual input timings during the past dialysis treatment are stored in the storage means 5, and the average value or the like is calculated. Even if the predicted loading timing is used, or if the consumption pattern (consumption tendency) of the undiluted solution for dialysis is constant for each day, the predicted loading timing is predicted based on the consumption pattern. Good.

If the storage means 5 does not store the actual input timing, such as when using this device for the first time or when performing a trial run, for example, one course (a unit of treatment performed in one day at a specific medical facility). It is assumed that it will take 30 minutes for preparation work, 30 minutes for blood return work, and 30 minutes for liquid replacement, and consider the start time of blood treatment and the number of patients (number of beds) for each course. By doing so, it is possible to predict the injection timing of the dialysis powder even if the actual injection timing is not stored.

In addition, if the total amount (number of bags) of dialysis powder on that day increases temporarily in the dissolution process, it is assumed that one patient has changed for each number of bags, and the actual data up to that point is for dialysis. The consumption tendency of the dialysis stock solution may be created by matching the consumption rate of the stock solution to predict the injection timing of the dialysis powder, and when the total amount (number of bags) of the dialysis powder increases permanently. Assuming that one patient is changed for each number of bags, the consumption tendency of the dialysis stock solution may be created by matching the consumption rate of the dialysis stock solution, and the timing of adding the dialysis powder may be predicted.

As described above, the display means 8 can display various indications related to the melting operation, and particularly in the present embodiment, as shown in FIG. 14, the display means 8 is configured to be able to display the predicted input timing predicted by the predictor 7. ing. Further, as shown in the figure, the display means 8 according to the present embodiment displays the number of additions and the amount of addition set by the setting means 6 together with the predicted input timing predicted by the predicting means 7. However, in the present embodiment, the predicted charging timing displayed by the display means 8 is set to "time", but it may be in another form in which the charging timing is known, for example, the elapsed time from the start of melting. It may be displayed as a predicted input timing.

Further, the prediction means 7 according to the present embodiment corrects the predicted input timing from the next time onward based on the additional input timing notified by the notification means 10, and causes the display means 8 to display the corrected predicted input timing. It is configured to get. For example, as shown in FIG. 17, the time difference (Δt) between the actual additional input timing notified by the notification means 10 and the predicted input timing predicted by the prediction means 7 at that time is calculated (S1), and the next time. By shifting the subsequent predicted input timing by the time difference (Δt) (S2), the predicted input timing is sequentially corrected, and the corrected predicted input timing is displayed on the display means 8.

Furthermore, in the present embodiment, the number of additions or the amount of addition set by the setting means 6 can be arbitrarily changed, and the prediction means 7 modifies the prediction input timing in response to the change. The display means 8 can display the corrected predicted input timing. For example, as shown in FIG. 15, when the additional amount of the dialysis powder in the first round is changed from 10 bags to 8 bags, the additional amount in the final round (the fourth round in the figure) is corrected accordingly. In addition to displaying, the predicted input timing for the second and subsequent times is shifted and displayed. Further, as shown in FIG. 16, it is also possible to reduce the amount of dialysate powder added at one time to 8 bags and increase the number of times of addition to 5 times.

When the additional amount (number of bags) is changed in this way, as shown in FIG. 19, the storage means 5 stores the tendency of consumption of the dialysis stock solution over time in the past dialysis treatment. Then, for example, as shown in FIG. 18, the amount of the dialysis stock solution generated from the changed number of bags is calculated (S1), and the time when the dialysis stock solution is consumed is stored in the storage means 5 (data (S1). After predicting (S2) from (the tendency of consumption of the undiluted solution for dialysis over time), the predicted charging timing after the number of bags is changed is corrected (S3), so that the corrected predicted charging timing is displayed on the display means 8. Will be displayed.

According to the above embodiment, based on the storage means 5 that can store the timing of adding the additional dialysis powder during the past dialysis treatment as the actual input timing and the actual input timing stored in the storage means 5. Predicting means 7 capable of predicting the timing of adding additional dialysis powder during dialysis treatment to be performed as predicted charging timing, and display means 8 capable of displaying the predicted charging timing predicted by the predicting means 7 are provided. Therefore, it is possible to make the operator know in advance the timing of adding the additional dialysis powder.

In addition, the total amount of dialysis powder required for dialysis treatment can be input, and based on the input total amount of dialysis powder, the number of additional dialysis powders to be added and the number of additional dialysis powders to be added are added. A setting means 6 capable of setting an additional amount of the dialysis powder to be charged at the timing is provided, and the display means 8 can display the number of additions and the additional amount set by the setting means 6 together with the predicted charging timing. Therefore, it is possible to make the operator know in advance the timing of adding the additional dialysis powder along with the number of additions and the amount of addition.

Further, the number of additions or the amount of addition set by the setting means 6 can be arbitrarily changed, and the prediction means 7 corrects the predicted input timing in response to the change, and sets the corrected predicted input timing. Since it can be displayed by the display means 8, it is possible to automatically correct and display the deviation of the predicted input timing due to the change in the number of additions or the amount of addition.

Furthermore, the liquid level detecting means 9 capable of continuously and in real time detecting the liquid level of the dialysis stock solution contained in the dissolution tanks (2, 3) and the dialysis stock solution detected by the liquid level detecting means 9 A notification means 10 capable of notifying the additional injection timing of the dialysis powder based on the liquid level is provided, and the prediction means 7 predicts the next and subsequent additional injection timings based on the additional injection timing notified by the notification means 10. Is corrected, and the corrected predicted input timing can be displayed on the display means 8. Therefore, if the predicted input timing deviates from the actual additional input timing notified by the notification means 10, the deviation is corrected. Can be displayed, and the predicted input timing can be predicted accurately.

In particular, the storage means 5 according to the present embodiment stores the actual input timing for each specific treatment day (every day in the present embodiment) corresponding to the treatment schedule (treatment cycle) of the patient in the medical facility, and is a prediction means. In No. 7, since the predicted input timing for each specific treatment day can be predicted and displayed by the display means, the predicted input timing can be predicted more accurately in the dialysis treatment in which the treatment schedule of the patient is predetermined.

Further, since the predicted charging timing displayed by the display means 8 is the time or the elapsed time from the start of dissolution, it is possible to make the operator more accurately grasp the charging timing of the additional dialysis powder. it can. In the present embodiment, the number of additions and the amount of addition set by the setting means 6 are displayed as a table together with the predicted input timing, so that the timing of addition can be visually grasped. These displays may be displayed as graphs or the like other than tables.

Although the present embodiment has been described above, the present invention is not limited to this, and as shown in FIG. 20, for example, a storage means M for storing a predetermined amount of dialysis powder and a dialysis powder in the storage means M. It may be applied to a dissolving device having a feeder F capable of supplying a predetermined amount of the agent to the dissolving tank T and a weighing scale S capable of measuring the weight of the dialysis powder in the accommodating means M over time. In this case, the additional dialysis powder is charged to the accommodating means M, the actual charging timing is stored, and the predicted charging timing can be predicted and displayed on the display means 8.

Further, the dissolution apparatus 1 according to the present embodiment includes a first dissolution tank 2 and a second dissolution tank 3 for adding and dissolving a dialysis powder, but includes one dissolution tank. Alternatively, it may be applied to those provided with three or more melting tanks. Further, the storage means 5 stores the actual input timing for each day of the week, and the display means 8 displays the predicted input timing for each day of the week, but for each specific treatment day corresponding to the treatment schedule of the patient in the medical facility. If there is, it may be another schedule.

Based on the storage means that can memorize the timing of adding the additional dialysis powder during the past dialysis treatment as the actual input timing and the actual input timing memorized by the storage means, the additional dialysis treatment to be performed in the future. If the dissolution device is provided with a predicting means capable of predicting the timing of charging the dialysis powder as a predicted charging timing and a display means capable of displaying the predicted charging timing predicted by the predicting means, the appearance shape is different. Alternatively, it can be applied to those to which other functions are added.
