Regarding the technical means of our inventors, several preferred embodiments are described in detail below in conjunction with the drawings, in order to provide a thorough understanding and approval of the present invention.

Hereinafter, an embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a schematic configuration of a dialysis system 100 including a hydrogen-dissolved water generator 1 of the present embodiment. The hydrogen-dissolved water generator 1 is a device for generating hydrogen-dissolved water in a dialysis system 100 that uses a dialysate prepared with hydrogen-dissolved water.

The dialysis system 100 includes a reverse osmosis membrane processing device 2, a hydrogen-dissolved water generating device 1, a dialysate preparation device 5, and a dialysis device 6.

The reverse osmosis membrane treatment device 2 purifies the raw water through reverse osmosis treatment, and supplies it to the hydrogen-dissolved water generator 1. Although tap water is generally used as raw water, other water, such as well water, ground water, etc., can be used in addition to this.

The reverse osmosis membrane treatment device 2 includes a water softening treatment device 21, an activated carbon treatment device 22 and a reverse osmosis membrane module 23. The water softening treatment device 21 removes hardness components such as calcium ions and magnesium ions from the raw water to soften the water. The activated carbon treatment device 22 has activated carbon as a fine porous substance, and adsorbs or removes chlorine and the like from the water supplied from the water softening treatment device 21. The reverse osmosis membrane module 23 separates the water supplied from the activated carbon treatment device 22 into treated water purified by the reverse osmosis membrane and concentrated water containing impurities. The treated water purified by the reverse osmosis membrane module 23 is sent to the hydrogen-dissolved water generator 1. On the other hand, the concentrated water that failed to pass through the reverse osmosis membrane is discharged to the outside of the reverse osmosis membrane treatment device 2.

The hydrogen-dissolved water generator 1 hydrogenates the water purified by the reverse osmosis membrane treatment unit 2 to generate hydrogen-dissolved water. The hydrogen-dissolved water generator 1 includes a hydrogen-dissolved water generator 3 for generating hydrogen-dissolved water (hydrogen-containing water) in which hydrogen gas is dissolved. In this embodiment, the electrolytic cell 4 is applied as a part of the hydrogen water generator 3. The details of the electrolytic cell 4 will be described later. The hydrogen-dissolved water produced by the hydrogen water producing unit 3 is sent to the dialysate preparation device 5 as dialysate preparation water.

The dialysate preparation device 5 uses the dialysate preparation water supplied from the hydrogen water generating unit 3 to, for example, dilute a liquid dialysis agent to prepare a dialysate. The dialysate prepared by the dialysate preparation device 5 is sent to the dialysis device 6.

The dialysis device 6 includes a dialysate supply device 61 and a dialyzer 62. The dialysate supply device 61 sends out the dialysate supplied from the dialysate preparation device 5 to the dialyzer 62. The dialyzer 62 is, for example, an artificial kidney including a dialysis membrane 62a composed of a porous membrane such as hollow fibers, and causes the dialysate supplied from the dialysate preparation apparatus 5 via the dialysis membrane 62a to act on the blood of the patient H undergoing dialysis treatment. Remove metabolic waste and water.

The patient H and the dialyzer 62 are connected through blood circuits 63 and 64. The blood circuit 63 sends the blood collected from the patient H to the dialyzer 62. The blood circuit 63 is provided with a pump 65 for sending blood. The blood circuit 64 returns the blood from which metabolic wastes and the like have been removed by the dialyzer 62 to the patient H.

The hydrogen-dissolved water generating device 1 includes, in addition to the above-mentioned hydrogen water generating unit 3, a collection unit 11 for collecting the exhalation of the patient H, a detection unit 12 for detecting the hydrogen contained in the exhalation of the patient H, and a In the control unit 13 that controls the hydrogen water generating unit 3.

The collection unit 11 is attached to the nose and the corner of the mouth of the patient H, collects the breath of the patient H, and sends it to the detection unit 12.

The detection unit 12 detects the amount of hydrogen contained in the breath of the patient H, and outputs a corresponding electric signal to the control unit 13. The detection unit 12 can employ a known hydrogen gas detector or the like. In the form of adopting the detection unit 12 capable of detecting hydrogen gas from the breath of the patient H, etc., the collection unit 11 is unnecessary.

The control unit 13 is composed of, for example, a CPU (Central Processing Unit) that executes various arithmetic processing, information processing, and the like, and a memory that stores programs and various information in charge of the operation of the CPU. The control unit 13 is responsible for the control of each unit of the hydrogen-dissolved water generator 1.

More specifically, the control unit 13 controls the hydrogen water generating unit 3 based on the electrical signal input from the detection unit 12, that is, the detection result of the detection unit 12. For example, when hydrogen gas is detected in the breath of the patient H, it can be confirmed that the hydrogen added by the hydrogen water generator 3 is absorbed by the dialysate and blood throughout the body of the patient H. Therefore, the hydrogen water generator 3's actions are weakened or stopped.

On the other hand, if hydrogen is not detected in the breath of the patient H, it can be confirmed that the hydrogen has not spread throughout the body of the patient H. Therefore, for example, the operation of the hydrogen water generating unit 3, that is, the generation of hydrogen-dissolved water is continued. In this case, the control unit 13 may also control the operation of the hydrogen water generating unit 3 to increase the dissolved hydrogen concentration.

Therefore, according to the hydrogen-dissolved water generator 1, it is possible to appropriately control the production of hydrogen-dissolved water used for the preparation of the dialysate in accordance with the hydrogen delivered to the body of the patient H.

In the present hydrogen-dissolved water generating device 1, it is preferable that the detecting unit 12 detects the amount of hydrogen per unit volume of exhalation, and the control unit 13 controls the hydrogen water generating unit 3 based on the amount of hydrogen detected by the detecting unit 12 . For example, the control unit 13 calculates the amount of hydrogen gas per unit volume of exhalation and compares it with a first threshold set in advance, thereby appropriately controlling the hydrogen water generator 3. The first threshold value can be defined by, for example, statistically processing information related to the transition of the symptoms of the patient H (hereinafter, the same applies to the second threshold value to the sixth threshold value). In such a configuration, the hydrogen water generator 3 can be appropriately controlled in accordance with the concentration of hydrogen gas in the breath.

In addition, as the amount of the above-mentioned hydrogen, in addition to mass, volume, molecular weight, etc. may also be used. In addition, the control unit 13 may be configured to calculate the amount of hydrogen contained in the breath exhaled by the patient H per unit time.

In addition, in the present hydrogen-dissolved water generator 1, the control unit 13 may be configured to control the hydrogen-water generator 3 based on the amount of hydrogen per unit volume of exhalation. For example, the control unit 13 controls the hydrogen water generator 3 by calculating the average value of the amount of hydrogen per unit volume of the exhalation and comparing it with a preset second threshold value. The control unit 13 preferably calculates a moving average value for each fixed period of time as the form of the above average value. In such a configuration, the hydrogen water generator 3 can be appropriately controlled without being affected by slight fluctuations in the concentration of hydrogen in the breath.

In addition, in the present hydrogen-dissolved water generating device 1, the control unit 13 may be configured to control the hydrogen water generating unit 3 based on the cumulative value of the amount of hydrogen detected by the detecting unit 12. For example, the control unit 13 calculates the cumulative value of the amount of hydrogen gas detected by the detection unit 12 and compares it with a preset third threshold value, thereby controlling the hydrogen water generating unit 3. In such a configuration, the hydrogen water generator 3 can be appropriately controlled based on the hydrogen gas accumulated in the body of the patient H.

In the present hydrogen-dissolved water generating device 1, it is preferable to further include a notification unit 14 that notifies the amount of hydrogen gas. The notification unit 14 uses, for example, a speaker device that outputs a sound signal and the like, in addition to an LED that outputs a light signal and the like. The notification can also use both light and sound signals. The operation of the notification unit 14 is controlled by, for example, the control unit 13. By providing the notification unit 14 in the hydrogen-dissolved water generating device 1, the doctor, nurse or patient H can know through the notification unit 14 that hydrogen has reached the body of the patient H.

FIG. 2 shows the electrolytic cell 4 constituting the hydrogen water generating unit 3. The electrolytic cell 4 electrolyzes water to generate hydrogen molecules. By dissolving the hydrogen molecules in water, hydrogen-dissolved water that is water to which the first hydrogen is added is generated.

The electrolysis tank 4 includes an electrolysis chamber 40, and a first power supply body 41 and a second power supply body 42 are provided in the electrolysis chamber 40. The first power supply body 41 and the second power supply body 42 are installed in the electrolysis chamber 40.

A diaphragm 43 is provided between the first power supply body 41 and the second power supply body 42. The electrolysis chamber 40 is divided into a first electrode chamber 40 a provided with a first power supply body 41 and a second electrode chamber 40 b provided with a second power supply body 42 by a diaphragm 43.

The polarities of the first power supply 41 and the second power supply 42 and the voltage applied to the first power supply 41 and the second power supply 42 are controlled by the control unit 13.

The current supply line between the power supply bodies 41 and 42 and the control unit 13 is provided with a current detector. The current detector detects the electrolysis current supplied to the first power supply body 41 and the second power supply body 42 and outputs an electric signal corresponding to the value to the control unit 13.

The control unit 13 controls the DC voltage applied to the first power supply body 41 and the second power supply body 42 based on the electrical signal output from the current detector, for example. More specifically, the control unit 13 performs feedback control on the DC voltage applied to the first power supply 41 and the second power supply 42 so that the electrolysis current detected by the current detector becomes a predetermined desired value. For example, when the electrolysis current is too large, the control unit 13 reduces the above-mentioned voltage, and when the electrolysis current is too small, the control unit 13 increases the above-mentioned voltage. Thereby, the electrolysis current supplied to the first power supply body 41 and the second power supply body 42 is appropriately controlled.

Hydrogen and oxygen are generated by electrolyzing water in the electrolysis chamber 40. For example, hydrogen gas is generated in the second electrode chamber 40b on the cathode side, and hydrogen-dissolved water in which the hydrogen molecules are dissolved is generated, and the hydrogen-dissolved water is supplied to the reverse osmosis membrane module 23 of the reverse osmosis membrane treatment device 2. In addition, the hydrogen-dissolved water produced with such electrolysis is also called "electrolyzed hydrogen water", and the dialysis treatment using electrolyzed hydrogen water is also called "electrolyzed water dialysis". On the other hand, oxygen is generated in the first electrode chamber 40a on the anode side.

As the separator 43, for example, a solid polymer film made of a fluorine-based resin having a sulfonic acid group is used as appropriate. The solid polymer membrane uses electrolysis to move oxonium ions generated in the first electrode chamber 40a on the anode side to the second electrode chamber 40b on the cathode side as a raw material for hydrogen generation. Therefore, no hydroxide ions are generated during electrolysis, and the pH of the hydrogen-dissolved water does not change.

In this embodiment, the control unit 13 is preferably configured to control the amount of hydrogen supplied to the first power supply body 41 and the second power supply body 42 for electrolysis based on the amount of hydrogen per unit volume of the exhaled breath detected by the detection unit 12 The current to make the dissolved hydrogen concentration of the hydrogen-dissolved water increase or decrease.

More specifically, when the amount of hydrogen per unit volume of the expiration detected by the detection unit 12 is less than a preset threshold, the control unit 13 will supply to the first power supply 41 and the second power supply 42 The electrolysis current is controlled to be larger. On the other hand, when the amount of the hydrogen gas is greater than the preset threshold value, the control unit 13 controls the current for electrolysis supplied to the first power supply body 41 and the second power supply body 42 to be small.

In addition, when the average value or the cumulative value of the hydrogen gas amount detected by the detection unit 12 is less than a preset threshold value, the control unit 13 may be configured to supply the power supply to the first power supply body 41 and the second power supply body 42. The electrolysis current is controlled to be larger. On the other hand, when the average value or cumulative value of the amount of hydrogen is greater than a preset threshold, the control unit 13 can control the current supplied to the first power supply body 41 and the second power supply body 42 for electrolysis to be small. .

In addition, the control unit 13 may be configured to control the current for electrolysis supplied to the first power supply body 41 and the second power supply body 42 based on the combination of the average value and the cumulative value of the amount of hydrogen per unit volume of exhalation. It's bigger.

FIG. 3 shows the processing process of the hydrogen-dissolved water generating method 500 used in the hydrogen-dissolved water generating device 1. The hydrogen-dissolved water production method 500 is executed in a dialysis treatment using a hydrogenated dialysate, and includes a production step S1, a detection step S21, S22, and a control step S3, S4, and S5.

In the production step S1, the hydrogen-dissolved water is produced by the hydrogen-water production unit 3. During the execution of dialysis treatment, in principle, the generation of hydrogen-dissolved water is continued.

In the detection step S21, the collection unit 11 attached to the corner of the mouth of the patient H collects the breath of the patient H during dialysis. In the detection step S22, the detection unit 12 detects the hydrogen contained in the breath collected in the detection step S21. In the control steps S3 and S4, the control unit 13 controls the hydrogen water generator 3 based on the detection result (the presence or absence of hydrogen) in the detection step S22. That is, when hydrogen gas is detected from the breath (Yes in S3), it can be judged that the hydrogen gas has spread throughout the body of the patient H, and therefore the operation of the hydrogen water generator 3 is weakened or stopped (S4). For example, in the control step S4, the control unit 13 weakens or cuts off the current used for electrolysis.

On the other hand, when hydrogen is not detected from the breath (No in S3), the operation of the hydrogen water generator 3 is controlled (S5) to increase the dissolved hydrogen concentration, and the process returns to S21. For example, in the control step S5, the current used by the control unit 13 for electrolysis increases.

According to the present hydrogen-dissolved water production method 500, the production of hydrogen-dissolved water used for the preparation of dialysate can be appropriately controlled based on the hydrogen delivered to the body of the patient H.

FIG. 4 shows a hydrogen-dissolved water generating method 500A as a modification of the hydrogen-dissolved water generating method 500 of FIG. 3. Regarding the parts not described below in the hydrogen-dissolved water generating method 500A, the treatment process of the above-mentioned hydrogen-dissolved water generating method 500 can be adopted.

In the hydrogen-dissolved water production method 500A, the control steps S31 and S32 are applied in addition to the control steps S3, S4, and S5 of the hydrogen-dissolved water production method 500. In the control steps S3, S31, S32, S4, and S5, the control unit 13 calculates the amount of hydrogen gas per unit volume of exhalation based on the detection result in the detection step S22 to control the operation of the hydrogen water generator 3.

That is, when hydrogen gas is detected from the breath in the control step S3 (YES in S3), the process proceeds to the control step S31. In the control step S31, the control unit 13 calculates the amount of hydrogen per unit volume of the breath based on the detection result in the detection step S22. Then, when the amount of hydrogen is equal to or greater than the first threshold value (YES in S32), the process proceeds to S4. It can be configured to return to S21 after executing S4.

On the other hand, when the amount of hydrogen is less than the first threshold value (No in S32), after shifting to S5, it returns to S21. In the hydrogen-dissolved water production method 500A, the control unit 13 controls the operation of the hydrogen-water production unit 3 according to the concentration of hydrogen in the breath, and therefore can appropriately control the production of the hydrogen-dissolved water used for the preparation of the dialysate.

FIG. 5 shows a hydrogen-dissolved water production method 500B as a modification of the hydrogen-dissolved water production method 500A of FIG. 3. Regarding the parts that are not described below in the hydrogen-dissolved water generating method 500B, the treatment process of the above-mentioned hydrogen-dissolved water generating method 500A and the like can be adopted.

In the hydrogen-dissolved water production method 500B, the control steps S33 and S34 are applied instead of the control steps S31 and S32 of the hydrogen-dissolved water production method 500A. In the control steps S3, S33, S34, S4, and S5, the control unit 13 calculates the average value of the amount of hydrogen per unit volume of exhalation based on the detection result in the detection step S22, and controls the operation of the hydrogen water generator 3 .

That is, when hydrogen gas is detected from the breath in the control step S3 (YES in S3), the process proceeds to the control step S33. In the control step S33, the control unit 13 calculates the average value of the amount of hydrogen per unit volume of the breath based on the detection result in the detection step S22. Then, when the average value of the amount of hydrogen is equal to or greater than the second threshold value (YES in S34), the process moves to S4. On the other hand, when the average value of the amount of hydrogen is less than the second threshold value (No in S34), after moving to S5, it returns to S21. In the hydrogen-dissolved water production method 500B, the operation of the hydrogen-water generator 3 is controlled based on the average value of the hydrogen concentration in the exhalation. Therefore, it is not affected by the slight fluctuation of the hydrogen concentration in the exhalation, and can be appropriately Control the generation of hydrogen-dissolved water used in the preparation of dialysate

FIG. 6 shows a hydrogen-dissolved water generating method 500C as another modification of the hydrogen-dissolved water generating method 500A of FIG. 3. Regarding the following unexplained parts of the hydrogen-dissolved water production method 500C, treatment processes such as the above-mentioned hydrogen-dissolved water production method 500A can be used.

In the hydrogen-dissolved water production method 500C, the control steps S35 and S36 are applied instead of the control steps S31 and S32 of the hydrogen-dissolved water production method 500A. In the control steps S3, S35, S36, S4, and S5, the control unit 13 calculates the cumulative value of the amount of hydrogen per unit volume of exhalation based on the detection result in the detection step S22, thereby controlling the operation of the hydrogen water generator 3 .

That is, when hydrogen gas is detected from the breath in the control step S3 (YES in S3), the process proceeds to the control step S35. In the control step S35, the control unit 13 calculates the cumulative value of the hydrogen gas amount based on the detection result in the detection step S22. Then, when the cumulative value of the amount of hydrogen is equal to or greater than the third threshold (YES in S35), the process proceeds to S4. On the other hand, when the cumulative value of the amount of hydrogen is less than the third threshold (No in S36), after shifting to S5, it returns to S21. In the hydrogen-dissolved water production method 500C, the operation of the hydrogen-water production unit 3 is controlled based on the cumulative value of the amount of hydrogen. Therefore, the hydrogen dissolved in the preparation of the dialysate can be appropriately controlled based on the hydrogen accumulated in the body of the patient H The generation of water.
