以下に実施の形態を、図面を用いて具体的に説明する。以下の説明においては、生理食塩水を収容した輸液パックを、液体パックの一例として説明する。また、富加とは、混合物において特定物質の割合を高めた状態をいう。本明細書においては、液体に水素を富加するとは、液体に分子状態の水素を添加することにより含まれる水素の濃度を所定値以上にすることをいう。図1は水素富加装置1の構成例を示す説明図である。水素富加装置1は水素発生部11、配管部12、収納部13を含む。なお、液体パックは、輸液ではなく注射液が入ったものでも良い。
Embodiments will be specifically described below with reference to the drawings. In the following description, an infusion pack containing physiological saline will be described as an example of a liquid pack. In addition, richness refers to a state in which the ratio of a specific substance in the mixture is increased. In the present specification, enriching hydrogen in a liquid means that the concentration of hydrogen contained in the liquid is increased to a predetermined value or more by adding molecular hydrogen to the liquid. FIG. 1 is an explanatory diagram showing a configuration example of the
実施の形態2は、各収納部13に水素ガスを供給する第5配管125に減圧弁12Bを設けた形態に関する。図6は水素富加装置1の構成例の一部を示す説明図である。図6に示していない構成は、実施の形態1と同様である。図6に示すように各第5配管125には第3オンオフ弁129の上流(水素発生部11に近い側)に、減圧弁12Bが設けてある。減圧弁12Bは一次側から流入したガスの圧力を下げて、二次側から流出する機能を備える弁である。本実施の形態の水素富加装置1では、水素発生部11に近い側(図6において左側)が一次側であり、第3オンオフ弁129側(図6において右側)が、二次側である。減圧弁12Bは、水素発生部11で発生させた水素を減圧して、収納部13に供給する。減圧弁12Bは2次側から流出する水素の圧力を所定の幅で変更できる可変型が望ましい。
The second embodiment relates to a mode in which a pressure reducing valve 12B is provided in a
実施の形態3は水素富加装置1を水素水生成システムにて使用する形態に関する。図7は水素水生成システムの構成例を示す説明図である。水素水生成システムは、水素富加装置1、ウォーターサーバ2を含む。水素富加装置1は、上述の実施の形態とほぼ同様な構成であるが、水素富加部15を含む点で異なる。以下の説明では、主に水素富加部15について説明する。ウォーターサーバ2は外部タンク21、内部タンク22を含む。
The third embodiment relates to a mode in which the
今回開示された実施の形態はすべての点で例示であって、制限的なものでは無いと考えられるべきである。本発明の範囲は、上記した意味では無く、特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。 The technical features (components) described in each embodiment can be combined with each other, and a new technical feature can be formed by combining them.
The embodiments disclosed herein are illustrative in all respects and should not be considered as restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
