Thereby, the liquid-receiving container 14 is hermetically accommodated in the housing section 13. [ The content of the accommodating portion 13 is, for example, 350 mL, and the internal pressure is 0.3 MPa (3 bar). In this case, it is very suitable for accommodating the liquid pack 14 of 250 mL in capacity in the accommodating portion 13. Incidentally, in the configuration shown in Fig. 1, the storage section 13 is provided in two, but it may be three or more in one contribution.

Next, a method for generating hydrogen in the hydrogen generator 11 will be described. Magnesium hydride as a raw material is a compound that is chemically bonded to hydrogen between metal atoms of magnesium and has a property of reacting with water according to the hydrolysis reaction shown in the following formula (1) to decompose while releasing hydrogen. According to the hydrolysis reaction represented by the formula (1), hydrogen of 15.2 [wt%] of magnesium hydride is generated.

MgH ₂ + 2H ₂ O? Mg (OH) ₂ + 2H ₂ ? (One)

It is also preferable to add citric acid as a catalyst. By adding citric acid, it becomes possible to speed up the chemical reaction of the formula (1). The necessary amount of citric acid is mixed with magnesium hydride in advance. Magnesium hydride and citric acid cause a chemical reaction in the following formula (2) to generate hydrogen.

_{3MgH 2 + 2C 6 H 8 O} 7 → Mg 3 (C 6 H 5 O 7) 2 + 6H 2 ... (2)

Subsequently, the order of hydrogen addition to the liquid-receiving pack 14 by the hydrogen addition device 1 will be described. Fig. 2 is a flowchart showing a procedure of hydrogen addition by the hydrogen addition device 1. Fig. First, all the on-off valves (the first on-off valve 127 to the third on-off valve 129) are turned off (step S1). The liquid receiver 14 is stored in the storage unit 13 (step S2). A magnesium hydride mixture of citric acid in the body portion 111 of the hydrogen generator (11) (MgH ₂₎ to set a predetermined amount (step S3). Way valve 126 is operated to make the first pipe 121 and the second pipe 122 communicate with each other (step S4). More specifically, water (H ₂ O) is injected into the first pipe 121, water in an amount sufficient for the hydrolysis reaction of magnesium hydride is injected into the syringe, water is injected from the open end of the first pipe 121 do. The water injected from the first pipe 121 passes through the three-way valve 126 and the second pipe 122 and is injected into the main body 111 of the hydrogen generating portion 11. When the injection of the predetermined amount of water is finished, the three-way valve 126 is operated to quickly complete the fully closed state (step S5). Accordingly, hydrogen generated in the first pipe 121 and the third pipe 123 from the pipe of the second pipe 122 does not go out. As the reaction progresses, the pressure in the main body 111 rises. When the internal pressure of the main body 111 reaches a predetermined value in the pressure gauge 114, the three-way valve 126 is operated and the second piping 122 and the third piping 123 are communicated with each other (step S6). The on-off valve is turned on (step S7). More specifically, the first on-off valve 127, the second on-off valve 128, and the third on-off valve 129 are turned on in this order. It is determined whether or not the time required for addition has elapsed and the pressure has reached a predetermined value (step S8). If it is determined that the time required for addition has not elapsed (NO in step S8), the determination is continued. It is further determined whether or not the pressure gauge 114 provided between the third on-off valve 129 and the accommodating portion 13 has reached a predetermined value (YES in Step S8) Off valve is turned off (step S9). Specifically, the third on-off valve installed in the fifth pipe 125 connected to the accommodating portion 13 in which the fluid pack 14 to be taken out is accommodated is closed. And takes out the liquid pack 14 (step S10).

In addition, although citric acid is previously mixed with magnesium hydride, it is not limited thereto. Instead of injecting water, a citric acid aqueous solution may be injected. Here, the injection of water or a citric acid aqueous solution by a syringe will be described with reference to the drawings. 3A, 3B and 3C are explanatory diagrams showing the order of injection of water or citric acid aqueous solution by the syringe. First, the syringe 3 and a required amount of water (H ₂ O) or citric acid aqueous solution (H ₂ O, C ₆ H ₈ O ₇ ) are prepared (FIG. When water is injected into the main body 111, a necessary amount of a mixture of magnesium hydride (MgH ₂ ) and citric acid (C ₆ H ₈ O ₇ ) is added. When the citric acid aqueous solution is injected, a necessary amount of magnesium hydride is added. The plunger 31 of the syringe 3 is pushed out toward the distal end. The tip of the needle 33 of the syringe 3 is immersed in a water or citric acid aqueous solution and the plunger 31 is pulled out from the syringe 32 to suck the aqueous solution of water or citric acid. Water or a citric acid aqueous solution is contained in the syringe 32 (Fig. 3B). The needle 33 of the syringe 3 is inserted from the tip of the first pipe 121 and then the plunger 31 is extruded to inject water or a citric acid aqueous solution into the main body 111 (Fig. For efficient operation, it is preferable to prepare each of magnesium hydride, citric acid, and water in an amount suitable for hydrolysis in advance. A mixture of magnesium hydride and citric acid, or magnesium hydride alone, is prepared to fill the required amount in an envelope formed of a water-permeable material such as a tea bag. Prepare a water or citric acid solution in a bottle in the required amount. Then, when a single batch of water is injected into one pack of a mixture of magnesium hydride and citric acid, metering of magnesium hydride and the like is not necessary every time, and the efficiency of the operation becomes possible. Incidentally, the concentration of the citric acid aqueous solution is preferably about 15 percent in the range from 0 deg. C to room temperature. When the concentration is about 15%, the chemical reaction of equation (1) is faster.

Next, a change with time in dissolved hydrogen concentration in the case where the solution pack 14 is left under an atmospheric pressure environment will be described. 4 is a graph showing an example of a change with time in dissolved hydrogen concentration. The vertical axis indicates dissolved hydrogen concentration, and the unit is ppm. The abscissa is the elapsed time after being left in an atmospheric pressure environment, and the unit is minutes. In the example shown in Fig. 4, a total of four physiological saline solution drip packs of Company A, Company B, Company C, and Company D were used as examples of the liquid receiver 14. Further, hydrogen was added to each of the drip packs, and the dissolved hydrogen concentration was set to about 1.57 ppm of the saturated concentration at atmospheric pressure, and then it was placed under an atmospheric pressure environment. Thus, the dissolved hydrogen concentration of each drip pack at elapsed time 0 is about 1.57 ppm. As shown in Fig. 4, at the time when 60 minutes passed, the dissolved hydrogen concentration in any drip pack was about 1.15 ppm. In addition, at 155 minutes, the dissolved hydrogen concentration was about 0.4 to 0.7 ppm. It is considered from the various treatments so far that the concentration of dissolved hydrogen is about 0.3 to 0.5 ppm so that the effect of the treatment is considered to be effective so that the dissolved hydrogen concentration of the drip pack is increased to the saturation concentration just before the start of the drip, Minute, a sufficient effect is expected.

Next, the relationship between the addition time of hydrogen and the dissolved hydrogen concentration of the liquid pack 14 will be described. 5 is a graph showing an example of the relationship between the addition time of hydrogen and the dissolved hydrogen concentration of the fluid pack 14. As shown in FIG. 5, the vertical axis represents the dissolved hydrogen concentration of the liquid pack 14, and the unit thereof is ppm. The abscissa represents the elapsed time from the addition start, that is, the addition time, and the unit is minutes. 5 shows the relationship between the additional time and the dissolved hydrogen concentration for each of the different internal pressures of the accommodating portion 13. As shown in Fig. The liquid-receiving pack 14 used for measurement is the above-described physiological saline solution dispensing pack of Company A.

As shown in FIG. 5, when the internal pressure was 0.02 MPa, the dissolved hydrogen concentration was about 0.5 ppm at the elapsed time of 120 and the dissolved hydrogen concentration was about 0.8 ppm at the elapsed time of 240 minutes.

When the internal pressure was 0.05 MPa, the dissolved hydrogen concentration was about 0.8 ppm at the elapsed time of 120 minutes, and the dissolved hydrogen concentration was about 0.9 ppm at the elapsed time of 240 minutes.

When the internal pressure was 0.1 MPa, the dissolved hydrogen concentration was about 0.9 ppm at the elapsed time of 120 minutes, the dissolved hydrogen concentration was about 1.3 ppm at the elapsed time of 210 minutes, and the dissolved hydrogen concentration was about 1.4 ppm at the elapsed time of 240 minutes.

When the internal pressure was 0.2 MPa, the dissolved hydrogen concentration was about 0.8 ppm at the elapsed time of 30 minutes, the dissolved hydrogen concentration was about 1.1 ppm at the elapsed time of 60 minutes, the dissolved hydrogen concentration was about 1.3 ppm at the elapsed time of 120 minutes, At the elapsed time of 240 minutes, the dissolved hydrogen concentration became about 1.5 ppm.

When the internal pressure was 0.3 MPa, the dissolved hydrogen concentration was about 1.1 ppm at the elapsed time of 60 minutes, the dissolved hydrogen concentration became about 2 ppm at the elapsed time of 150 minutes, and the elapsed time from 120 minutes to about 1.7 ppm.

From the above results, when the internal pressure is 0.3 MPa, the dissolved hydrogen concentration becomes about 1.7 ppm at an elapsed time of 120 minutes, which is a value exceeding about 1.57 ppm of the saturated concentration at normal pressure, .

Next, a calculation example of a necessary amount of magnesium hydride or the like when the internal pressure is 0.3 MPa is shown. The conditions of calculation are as follows. The content of the main body portion 111 of the hydrogen generating portion 11 is made 300 mL. The number of the accommodating portions 13 is two, and the content of each of them is 350 mL. The total volume of the piping portion 12 connecting the main body portion 111 and the accommodating portion 13 is 100 mL. From the above conditions, the content of hydrogen addition device 1 becomes 1100 mL. Then, in each of the two storage units 13, a liquid pack 14 of 250 mL in volume is stored. Then, the content of the space that needs to be filled with hydrogen becomes 600 mL.

The volume of hydrogen required to maintain the internal pressure of 0.3 MPa is 1800 mL, three times the volume of 600 mL, since the atmospheric pressure is approximately 0.1 MPa.

The molecular weight of magnesium hydride is 26.32, the molecular weight of hydrogen is 2.0, and the molecular weight of citric acid is 192.12. 1 mole of gas is 22.4 L. From the above-mentioned formulas (1) and (2), two moles of hydrogen are generated per mole of magnesium hydride. Therefore, hydrogen generated in 1 g of magnesium hydride is obtained by the following formula (3).

22.4 (L) x 2 / 26.32 = about 1.7 (L) = about 1700 (mL) ... (3)

Since about 1700 mL of hydrogen is generated in 1 g of magnesium hydride, the required amount of magnesium hydride for generating 1800 mL of hydrogen is obtained from the following formula (4).

1800/1700 x 1 = about 1.05 (g) ... (4)

From the above formula (2), since the amount of citric acid is required to be 2 moles with respect to 3 moles of magnesium hydride, the required amount of citric acid relative to 1.05 g of magnesium hydride is obtained from the following formula (5).

1.05 / (3 x 26.32) x (2 x 192.12) = about 5.12 (g) ... (5)

In addition, although the required amount of water for 1.05 g of magnesium hydride is obtained from the formula (1), a larger amount of water than the theoretical value is required in an actual reaction. 15 times as much water as magnesium hydride is required in a weight ratio. Thus, the required amount of water is about 15.75 mL.

To summarize the above, 1.05 g of magnesium hydride, 15.75 mL of water, and 5.12 g of citric acid are required to fill 600 mL of internal volume with hydrogen of 0.3 MPa. With respect to each amount, it is acceptable to have a sufficient amount of margin.

As described above, when the dissolved hydrogen concentration is about 0.3 to 0.5 ppm, it is considered that there is a therapeutic effect. Therefore, when the liquid adding pack 14 is taken out of the containing section 13 in the hydrogen addition device 1, And the hydrogen generating portion 11 is made to function so as to be 0.3 ppm. Preferably, the dissolved hydrogen concentration of the solution pack 14 is 0.5 to 2 ppm.

The hydrogen addition device 1 of the first embodiment exhibits the following effects. It becomes possible to add hydrogen to the liquid pack 14 at a high concentration. For example, when the withstand pressure is 0.3 MPa, it is possible to increase the dissolved hydrogen concentration up to the saturated concentration in about 120 minutes.

The hydrogen addition device 1 can also monitor the pressure of hydrogen by providing a pressure gauge 114 in the main body 111. [ The pressure of hydrogen applied to the liquid receiver 14 is accurately monitored by providing a pressure gauge 114 between the third on-off valve 129 and the storage unit 13. [ The user can reliably raise the dissolved hydrogen concentration of the liquid pack 14 to a desired value by managing the pressure and the addition time. The hydrogen addition device 1 is capable of supplying hydrogen stored in the storage portion 13 to the storage portion 13 by providing the filter portion 12A. Thereby, even after adding hydrogen by the hydrogen addition device 1, the fluid pack 14 can satisfy the sanitary standard that can withstand use in a medical institution. The hydrogen adding device 1 includes a plurality of the accommodating portions 13, so that hydrogen can be added to a plurality of the liquid absorbing pads 14 at the same time.

In addition, water or an aqueous solution of citric acid and hydrogen may pass through the second pipe 122, but only hydrogen may pass through the second pipe 122. That is, a pipe for injecting water or a citric acid aqueous solution may be provided in the opening 112 separately from the second pipe 122. In addition, although the liquid-pouring bag 14 containing the liquid-receiving liquid is described as an example of the liquid pack, the present invention is not limited thereto. It may be a pack of injections containing the injectate. In addition, a beverage pack, a sports drink, juice, coffee, tea or the like may be a beverage pack housed in a film bag.

Embodiment 2

The second embodiment relates to a configuration in which a pressure reducing valve 12B is provided in a fifth pipe 125 for supplying hydrogen gas to each of the accommodating portions 13. 6 is an explanatory view showing a part of the configuration example of the hydrogen adding device 1. Fig. The configuration not shown in Fig. 6 is the same as that in the first embodiment. 6, a pressure reducing valve 12B is provided in each fifth pipe 125 on the upstream side of the third on-off valve 129 (on the side closer to the hydrogen generating unit 11). The pressure reducing valve 12B is a valve having a function of lowering the pressure of the gas introduced from the primary side and flowing out from the secondary side. 6) is on the primary side and the third on-off valve 129 side (on the right in Fig. 6) is located on the side of the hydrogen generating section 11 Side. The pressure reducing valve 12B decompresses the hydrogen generated in the hydrogen generator 11 and supplies it to the storage unit 13. [ It is preferable that the pressure reducing valve 12B is of a variable type in which the pressure of hydrogen flowing out from the secondary side can be changed to a predetermined width.

In the second embodiment, the pressure of hydrogen generated in the hydrogen generator 11 is set to, for example, 0.4 MPa and the pressure in the pressure reducing valve 12B is reduced to 0.3 MPa. The decompressed hydrogen is supplied to the storage portion (13). When it is desired to shorten the time for adding hydrogen to the fluid pack 14, the pressure of the hydrogen supplied to the storage portion 13 may be increased by adjusting the pressure reducing valve 12B.

The hydrogen adding device 1 of the second embodiment exhibits the following effects. By providing the pressure reducing valve 12B, the pressure of the hydrogen generated in the hydrogen generator 11 may be higher than a predetermined value, and it is not necessary to strictly control the pressure, so that the working efficiency increases. In addition, when the hydrogen-added fluid pack 14 is urgently needed, the hydrogen addition can be completed in a shorter time than usual if the pressure of the hydrogen supplied to the storage portion 13 is increased. Further, since the pressure reducing valve 12B is provided for each of the accommodating portions 13, the pressure of hydrogen can be changed for each accommodating portion 13. Thus, the time required for the hydrogen addition for each storage portion 13 can be adjusted.

Embodiment 3

Embodiment 3 relates to a mode in which the hydrogen addition device 1 is used in a hydrogen generation system. Fig. 7 is an explanatory diagram showing a configuration example of a hydrogen-producing system; Fig. The hydrogen generation system includes a hydrogen addition device 1 and a water server 2. The hydrogen addition device 1 is substantially the same as the above-described embodiment, but differs in that it includes the hydrogen addition portion 15. In the following description, mainly the hydrogen addition section 15 will be described. The water server 2 includes an external tank 21 and an internal tank 22.

The hydrogen addition apparatus 1 supplies hydrogen generated in the hydrogen generation unit 11 to the hydrogen addition unit 15 through a pipe. The hydrogen addition part 15 is provided with an additional pipe 151 therein. The addition tube 151 is formed of a resin that can permeate hydrogen gas, for example, polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP). The amount of hydrogen generated in the hydrogen generating portion 11 is adjusted so that the internal pressure of the hydrogen adding portion 15 filled with hydrogen is made higher than the normal pressure.

The external tank 21 of the water server 2 accommodates drinking water such as mineral water. The external tank 21 is replaceable. When the stored drinking water is absent, the water tank 2 can be continuously supplied with water by exchanging the external tank 21. The inner tank 22 includes an outlet 221, an inlet 222, a supply pipe 223, and a stop valve 224. The internal tank 22 is provided with a pump (not shown) for circulating water. Further, the inner tank 22 is divided into a partition 225.

The water in the water server 2 circulates in the additive pipe 151 of the hydrogen addition unit 15 by the above-described pump. The water from the outlet 221 at the upper portion of the inner tank 22 of the water server 2 enters the additional pipe 151 from the inlet 152 and exits from the outlet 153. The water from the outlet 153 returns from the inlet 222 to the lower portion of the inner tank 22. Hydrogen is added while water passes through the addition pipe 151.

The supply pipe 223 communicates with the lower portion of the inner tank 22. By opening the exponent valve 224 provided in the supply pipe 223, it is possible to adhere the hydrogen-added water collected under the inner tank 22 to the container such as a cup.

The hydrodynamic water generating system of Embodiment 3 exhibits the following effects. By circulating water in the hydrogen addition portion 15 filled with hydrogen, it is possible to generate hydrogen water at a high concentration. The hydrogen is added to the water through the addition pipe 151 of the hydrogen addition unit 15. [ Therefore, there is no fear that the minute foreign matter or the bacteria will mix with the circulating water.

In addition, in the water server 2, soft drinks such as juice, sports drinks, tea, and tea may be supplied instead of water.

In the hydrogen addition device 1 described above, the switching of the three-way valve 126 and the on-off of the first on-off valve 127 to the third on-off valve 129 have been explained on the assumption that a person performs them, It is not limited. It is also possible to control the on-off of the valve by a control unit such as a computer or a sequencer by using the respective valves as electric valves or solenoid valves. Further, it is also possible to provide a control mechanism for storing a plurality of magnesium hydride, citric acid, water and the like used for hydrolysis in appropriate amounts and automatically injecting a necessary amount in accordance with the internal pressure of the main body 111.

In Embodiments 1 to 3, the hydrogen generating portion 11 generates hydrogen by hydrolysis of magnesium hydride, but it is not limited thereto. Hydrogen may be generated by hydrolyzing other substances, for example, calcium hydride (CaH ₂ ), sodium borohydride (NaBH ₄ ), and metal salts. In the case of calcium hydride, hydrogen is generated by a chemical reaction represented by the following formula (6).

CaH ₂ + 2H ₂ O? Ca (OH) ₂ + 2H ₂ ? (6)

In the case of sodium borohydride, hydrogen is generated by the chemical reaction shown in the following formula (7).

NaBH ₄ + 2H ₂ O → NaBO ₂ + 4H ₂ ... (7)

The necessary amount of calcium hydride or sodium borohydride and water to be added to the hydrogen generating portion 11 when hydrogen is generated may be obtained by using the above-mentioned formula (6) or (7). Further, as in the case of magnesium hydride, a suitable catalyst for promoting the reaction may be used.

As described above, even when calcium hydride or sodium borohydride is used, it is possible to add hydrogen to the liquid or the like contained in the liquid-pouring solution 14 by using the generated hydrogen.

The technical features (constituent elements) described in each embodiment can be combined with each other, and a new technical characteristic can be formed by combining them.

The presently disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and is intended to include all modifications within the meaning and scope equivalent to those of the claims.
