Solution Overview
Problem
Medical substances stored in containers face deterioration due to oxygen exposure, especially when containers are opened and closed, which complicates long-term preservation and storage, especially for emergencies and disasters.
Innovation Solution
Incorporating a hydrogen-generating substance into the exterior sheet of medical containers that reacts with moisture to produce hydrogen, converting oxygen into harmless water, thereby preventing oxidation and extending the preservation period of medical substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If medical substances are enclosed in airtight containers, then protection from oxidation is improved, but air cannot be removed and small amounts of air enter during enclosing process
Solution Approach 1:
The patent converts the harmful oxygen that enters the container into beneficial hydrogen gas through chemical reaction with the hydrogen-generating substance. The oxygen is transformed into harmless water, turning the oxidation threat into a protective mechanism that actively removes oxygen and generates antioxidant hydrogen.
Solution Approach 2:
The hydrogen-generating substance acts as an intermediary between the introduced oxygen and the medical substance. Instead of oxygen directly oxidizing the medical substance, the intermediary substance reacts with oxygen first, converting it to water and generating hydrogen, thereby protecting the medical substance from direct oxidation.
2Ease of operation
If containers are opened and closed for repeated use, then accessibility is improved, but oxygen exposure increases and accelerates deterioration
Solution Approach 1:
The hydrogen-generating substance provides continuous oxygen removal and hydrogen generation throughout the storage period, regardless of how many times the container is opened. The chemical reaction continues as long as oxygen is present, maintaining continuous protection against oxidation even during repeated access operations.
Solution Approach 2:
The container system automatically protects itself from oxidation through the hydrogen-generating substance that reacts with introduced oxygen. The system serves itself by converting harmful oxygen into protective hydrogen without requiring external intervention, maintaining preservation quality despite repeated opening and closing operations.
3Object-affected harmful factors
If hydrogen-generating substance is added to exterior sheet, then oxidation prevention is improved, but device complexity increases
Solution Approach 1:
The hydrogen-generating substance is merged with the exterior sheet material itself, combining the container structure and the protective function into a single integrated component. This eliminates the need for separate protective devices or systems, maintaining simplicity while providing active oxidation prevention through the chemically active material embedded in the sheet.
Solution Approach 2:
The exterior sheet becomes a composite material combining the structural polymer matrix with dispersed hydrogen-generating substance particles. This composite structure provides both mechanical integrity and chemical protection functions within a single material system, avoiding the need for complex multi-component assemblies.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents oxidation of medical substances, lengthening their usable period and facilitating long-term storage by converting oxygen into water, even when containers are opened and closed repeatedly.
Implementation Method 1
a hydrogen-generating substance for generating hydrogen gas by reacting with moisture (liquid water or water vapor) from the enclosed medical substance
Implementation Method 2
oxygen in the medical container is converted to water which is harmless because the oxygen in the introduced air has high reactivity with the generated hydrogen

AI summary
A hydrogen-generating substance that reacts with moisture (liquid water or water vapor) in a medical substance or moisture in air introduced into a medical container is kneaded into an exterior sheet 40 of the medical container that encloses the medical substance therein. The medical container can be a bag-shaped medical container, a tube-shaped medical container, a medical container with a sealing fastener or the like. The medical substance containing moisture can be blood, an injection solution, a drug solution, a nutrient solution, a replenishment solution (an infusion solution), an instillation solution or the like. A solid preparation is preferably enclosed within the medical container with the sealing fastener. For example, the hydrogen-generating substance to be kneaded can be metal magnesium and is preferably fine-powdered ceramics obtained by firing the mixture of a hydrogen-generating substance and a mineral substance such as calcium.
