Description

TECHNICAL FIELD The present invention relates to a hydrogen gas delivery device capable of delivering a sufficient amount and concentration of hydrogen gas without using a suction device such as a cannula.

Hydrogen is said to have effects such as recovery from fatigue, rejuvenation, and beautiful skin by removing active oxygen in the body that causes aging and disease by its reducing power when taken into the body. In recent years, it has been discovered that hydrogen suppresses inflammation and active oxygen that occur in the body and promotes energy metabolism in cells, and is expected to play an active role in the prevention and treatment of various diseases. In addition, medical research on hydrogen is underway and is attracting attention.

Conventionally, as a method for introducing hydrogen into the human body, a method of directly inhaling hydrogen gas by attaching a hydrogen gas suction device such as a nasal cannula (Patent Document 1) or a gas suction mask (Patent Document 2) to the face has been proposed. there is

A hydrogen gas suction device described in Patent Document 1 includes a container for generating hydrogen gas, a connecting tube, and a nasal cannula. The generated hydrogen gas flows into the connecting tube, forms fine bubbles through fine through-holes formed in the porous material accommodated in the second container, and forms water that fills the second container. A part of it dissolves in the water and moves upward, then flows into the nasal cannula through the intermediate tube and is sucked into the user's nasal cavity.

Further, the hydrogen gas inhaler described in Patent Document 2 is composed of a main body, an operation part, a malfunction prevention device, and a cap. When the hydrogen gas inhaler is used, the hydrogen gas inhalation pipe is connected to the pipe connection part installed in the main body, and further leads to the inhaler (inhalation mask) worn by the user. Inside the hydrogen gas inhaler where the hydrogen gas generating agent and the reaction liquid are mixed, hydrogen gas is generated and stored in the upper part of the main body, and passes through the hydrogen gas inhalation pipe to the inhaler (inhalation mask) worn by the inhaler. ) to send hydrogen gas.

However, the hydrogen gas suction devices (hydrogen gas inhalers) described in Patent Documents 1 and 2 require a nasal cannula or a gas suction mask to be attached to the user's face, and are not suitable for use because they are medical procedures. Due to restrictions, it was not possible to use it easily. In addition, since a tube that supplies hydrogen gas is connected between a hydrogen gas suction device such as a nasal cannula or a gas suction mask and the hydrogen generator (or hydrogen storage container), the user can move freely. There was also the problem of not being able to Furthermore, there is also the problem that it is necessary to periodically purchase the hydrogen gas suction device as a consumable item.

A cylindrical inner nozzle for blowing out the forced air from the tip along the axial direction is provided so that the flow velocity of the air blown out from the outer nozzle is higher than the flow velocity of the hydrogen gas discharged from the hydrogen gas discharge nozzle. is configured to

Hydrogen gas is released in the axial direction from the hydrogen gas release nozzle, and air is blown out along the axial direction from the cylindrical outer nozzle installed coaxially outside the hydrogen gas release nozzle, coaxially between the hydrogen gas release nozzle and the outer nozzle. Air urged by the air blown out from the outer nozzle is blown out along the axial direction from the arranged cylindrical inner nozzle. In this way, a cushioning space is formed between the released hydrogen gas flow and the air flow with a high flow velocity on the outside to form an air flow, thereby suppressing the acceleration of the hydrogen gas and preventing its diffusion. can be done. As a result, a sufficient amount and concentration of hydrogen gas can be supplied to a user at a predetermined distance without using a suction device such as a nasal cannula.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 schematically shows the external configuration of a hydrogen gas delivery device 100 according to an embodiment of the present invention, and FIG. 2 shows the triple nozzle configuration and hydrogen gas delivery state of this hydrogen gas delivery device 100. .

As shown in FIG. 1, the hydrogen gas discharge device 100 according to the present embodiment includes a triple nozzle 10 for blowing out air and hydrogen, a hydrogen gas supply means 20, an air supply means 30 for blowing out air, and a control means. 40.

Further, as shown in FIG. 2, the triple nozzle 10 includes a hydrogen gas discharge nozzle 11 that discharges hydrogen gas supplied from the hydrogen gas supply means 20 along the axial direction from the tip, and an outer side of the hydrogen gas discharge nozzle 11. and is coaxially arranged between the cylindrical outer nozzle 12 that blows air supplied from the air supply means 30 along the axial direction from the tip, and the hydrogen gas discharge nozzle 11 and the outer nozzle 12. , and a cylindrical inner nozzle 13 for blowing out the air urged by the air blown out from the outer nozzle 12 from the tip along the axial direction. In this embodiment, the triple nozzle 10 further includes a spiral airflow forming means 14 provided at the tip between the outer nozzle 12 and the inner nozzle 13 to form a spiral airflow. A screw fin, for example, is used as the spiral airflow forming means 14 . By providing the spiral airflow forming means 14, it is possible to enhance the straight-ahead performance of the airflow and the hydrogen gas flow. In the triple nozzle 10 , the tip of the hydrogen gas discharge nozzle 11 is arranged behind the tip of the inner nozzle 13 , and the tip of the inner nozzle 13 is arranged behind the tip of the outer nozzle 12 . Thereby, diffusion of hydrogen gas can be suppressed. Further, the rear end side of the inner nozzle 13 is communicated with the outside air, and when the air is blown out from the outer nozzle 12 at high speed, the air inside the inner nozzle 13 is pulled and blown out from the tip, and at the same time, it is biased, A medium-velocity airflow (cushion space) having a flow velocity higher than that of hydrogen gas and lower than that of high-speed air is formed between the hydrogen gas and high-velocity air.

The hydrogen gas supply means 20 consists of a hydrogen gas generator. For this hydrogen gas generator, for example, a device that generates hydrogen by electrolysis of water is used. Hydrogen gas generators are a safe and convenient alternative to high pressure gas cylinders of hydrogen and are generally more cost effective to utilize. When a hydrogen gas generator is used, it is possible to produce hydrogen gas with a purity of 99.999% by electrolyzing a required amount of water when required. As the hydrogen gas supply means 20, a commercially available small hydrogen gas cylinder or a hydrogen storage alloy canister may be used.

The air supply means 30 supplies air to the outer nozzle 12, and can be a blower fan, an axial fan, or a compressor. A blower fan is used as the air supply means 30 in this embodiment. The air flow supplied from the blower fan is rectified, so hydrogen gas can be delivered in a nearly straight line, and the high air velocity suppresses the decrease in concentration due to diffusion of hydrogen gas. can.

The control means 40 controls the hydrogen gas supply means 20 and the air supply means 30, and uses, for example, a microcomputer. The overall operation of the hydrogen gas suction device 100 is controlled according to the control program. In this embodiment, the control means 40 releases hydrogen gas from the hydrogen gas release nozzle 11 and blows air from the outer nozzle 12 when the user turns on the power. The operation of the hydrogen gas supply means 11 and the air supply means 12 is controlled so that the flow velocity of the air discharged from the hydrogen gas discharge nozzle 11 is higher than the flow velocity of the hydrogen gas discharged from the hydrogen gas discharge nozzle 11 . The control means 40 is also configured to control the hydrogen gas generation process of the hydrogen gas supply means 20 .

With such a configuration, when using the hydrogen gas discharge device 100 , hydrogen gas is discharged from the hydrogen gas discharge nozzle 11 of the triple nozzle 10 and air is blown out from the outer nozzle 12 . As a result, as shown in FIG. 2, an axial high-speed airflow having a velocity higher than the flow velocity of the hydrogen gas is formed outside the hydrogen gas flow. It becomes a high-speed spiral air flow that goes straight to Air from the inner nozzle 13 is energized by this high-speed spiral air flow, and a medium-speed air flow having a flow speed higher than the flow speed of the hydrogen gas and lower than the flow speed of the high-speed air flow is generated between the hydrogen gas flow and the high-speed spiral air flow. formed between A sufficient amount and concentration of hydrogen gas can be delivered to a predetermined distance while suppressing the diffusion of hydrogen gas by these high-speed spiral airflow and medium-speed airflow.

FIG. 3 shows, as another embodiment of the hydrogen gas delivery device of the present invention, the configuration of the triple nozzle 10a and the hydrogen gas delivery state in the absence of the spiral airflow forming means 14 shown in FIG.

As shown in FIG. 3, the triple nozzle 10a of this embodiment has a spiral airflow forming means 14 for forming a spiral airflow as shown in FIG. It has the same configuration as the triple nozzle 10 of the embodiment described above, except that is not provided. Since the triple nozzle 10a does not have a spiral airflow forming means for forming a spiral airflow, the air blown out from the outer nozzle 12 travels straight along the axial direction without swirling. The air from the inner nozzle 13 is energized by this straight high-speed air flow, and a medium-speed air flow (cushion space) having a flow speed higher than the flow speed of the hydrogen gas and lower than the flow speed of the high-speed air flow becomes the hydrogen gas flow. and a high velocity air stream. A sufficient amount and concentration of hydrogen gas can be delivered to a predetermined distance while suppressing the diffusion of hydrogen gas by these high-speed airflow and medium-speed airflow.

FIG. 4 shows a configuration example of a triple nozzle 10A and a state of hydrogen gas delivery as still another embodiment of the hydrogen gas delivery device of the present invention.

As shown in FIG. 4, the triple nozzle 10A includes a hydrogen gas discharge nozzle 11A that discharges hydrogen gas supplied from the hydrogen gas supply means 20 along the axial direction from the tip, and an outer tip of the hydrogen gas discharge nozzle 11A. A cylindrical outer nozzle 12A which is installed coaxially with the air supply means 30 and blows out the air supplied from the air supply means 30 along the axial direction from the tip, and is arranged coaxially between the hydrogen gas discharge nozzle 11 and the outer nozzle 12A. and a cylindrical inner nozzle 13A for introducing part of the air supplied from the air supply means 30 from the rear end side face and blowing it from the tip when the air is blown from the air blowing nozzle 12A. In this embodiment, the triple nozzle 10A further includes a spiral airflow forming means 14A provided at the tip between the outer nozzle 12A and the inner nozzle 13A for forming a spiral airflow. In the triple nozzle 10A, the tip of the hydrogen gas discharge nozzle 11A is arranged behind the tip of the inner nozzle 13A, and the tip of the inner nozzle 13A is arranged behind the tip of the outer nozzle 12A. Further, a plurality of openings are provided on the side surface of the inner nozzle 13A on the rear end side. It is designed to slow down the flow.

Further, in this embodiment, the tip of the triple nozzle 10A consisting of the hydrogen gas discharge nozzle 11A, the outer nozzle 12A and the inner nozzle 13A is integrally formed and can rotate within a predetermined angle range with respect to the axis. is configured to For example, as shown in FIG. 4, the rear end of the hydrogen gas discharge nozzle 11A is connected to the hydrogen gas supply means 20 via a flexible tube made of rubber or the like, and the rear end of the outer nozzle 12A is formed in a substantially sectoral shape when viewed from the side. ing. As a result, the tip of the triple nozzle 10A can be vertically rotated within a predetermined angular range, and the orientation of the triple nozzle 10A can be adjusted during use.

In the triple nozzle 10A, as shown in FIG. 4, the hydrogen gas is delivered when the hydrogen gas supplied from the hydrogen gas supply means 20 is released along the axial direction from the tip of the hydrogen gas release nozzle 11A. The air supplied from the means 30 is blown axially from the tip of the outer nozzle 12A through the spiral airflow forming means 14A, thereby forming a cylindrical high-speed airflow (spiral airflow). Part of the air supplied from the air supply means 30 is introduced from the rear end of the inner nozzle 13A, and is urged by the high-speed air flow so that the flow speed is higher than the flow speed of the hydrogen gas and lower than the flow speed of the high-speed air flow. A medium-velocity airflow (cushioning space) is formed between the hydrogen gas stream and the high-velocity spiral airflow. A sufficient amount and concentration of hydrogen gas can be delivered to a predetermined distance while suppressing the diffusion of hydrogen gas by these layers of high-speed air flow and medium-speed air flow.

In order to compare the hydrogen gas delivery effect, a comparative experiment was conducted between the hydrogen gas delivery device of the present invention and the hydrogen gas delivery device of the comparative example. FIG. 6 shows the configuration of a comparative experiment between the hydrogen gas delivery device 100 of the embodiment of FIGS. 1 and 2 and a comparative example. each show a configuration using a comparative example. As a comparative example, a blower fan in which a hydrogen gas discharge nozzle was installed at the air outlet was used. As a hydrogen concentration measuring device, a hydrogen gas measuring device UPX4 type (UPI Co., Ltd.) was used.

Experimental conditions: A hydrogen concentration measuring device was installed at a position 200 mm away from the tip of the triple nozzle 10 or the hydrogen gas nozzle. The flow rate of hydrogen gas was set at 100 mL/min, and the flow velocity of the air supplied from the air supply means 30 was set at 2.84 m/s. Table 1 shows the measurement results.

表１に示すように、図２の実施形態の水素ガス送出装置１００を用いた場合、３重ノズル１０の先端から２００ｍｍ離れた位置で、比較的高い水素濃度（１．２２５％）が維持され、水素吸引に適正な水素濃度が得られた（一般的な水素吸引では水素濃度が０．５％～２％である）。比較例では、２００ｍｍ離れた位置での水素濃度が大きく低下することが分かった。即ち、単なる高速空気流で水素を送出（搬送）しても、水素ガスの拡散により水素濃度の低下を抑えることができないことが分かった。

As shown in Table 1, when using the hydrogen gas delivery device 100 of the embodiment of FIG. 2, a relatively high hydrogen concentration (1.225%) is maintained at a position 200 mm away from the tip of the triple nozzle 10 , an appropriate hydrogen concentration was obtained for hydrogen aspiration (typical hydrogen aspiration has a hydrogen concentration of 0.5% to 2%). In the comparative example, it was found that the hydrogen concentration at a position 200 mm away was greatly reduced. In other words, it has been found that even if hydrogen is delivered (conveyed) by a mere high-speed air flow, the decrease in hydrogen concentration cannot be suppressed due to the diffusion of hydrogen gas.

Also, an experiment was conducted on the hydrogen gas delivery effect of the hydrogen gas delivery device 100 having the triple nozzle 10A in the embodiment of FIG. In this case, the hydrogen concentration measuring device was installed at a position separated by 500 mm from the tip of the triple nozzle 10A. The flow rate of hydrogen gas was 100 mL/min, and the flow velocity of the air supplied from the air supply means 30 was 2.84 m/s. The hydrogen concentration was measured to be 1.053%. As a result, when the hydrogen gas delivery device 100 in the embodiment of FIG. 4 is used, a relatively high hydrogen concentration is maintained even at a position 500 mm away from the tip of the triple nozzle 10A, and the hydrogen concentration appropriate for hydrogen suction is maintained.

FIG. 7 shows another usage state of the hydrogen gas suction device 100, in which hydrogen gas is sucked while doing other work near the hydrogen gas discharge device 100 installed on a table or the like. FIG. 8 shows still another use state of the hydrogen gas suction device 100, in which the hydrogen gas released from the hydrogen gas release device 100 installed near the bed is sucked during sleep.
