Description

Technical Field

[0001] The present invention relates to the technical field of medical care products, and in particular to a microreactor for in-situ generation of hydrogen and oxygen by electrocatalytic decomposition of body fluids. Background Art

[0002] Oxygen is the only final electron acceptor in living organisms, and no substance in the body can replace this gas. Without oxygen, aerobic cells will lose their ability to continuously accept electrons, and energy metabolism will not proceed smoothly.

[0003] Hydrogen molecular medicine is an emerging research field that has developed in the past decade. Hydrogen has the properties of anti-inflammatory and reducing oxidative stress, and has been used to relieve muscle fatigue and chronic inflammation. Hydrogen can diffuse rapidly in the human body and has been proven to be used for human treatment without causing any adverse reactions, but it requires long-term inhalation of hydrogen to work. The hydrogen inhalation equipment currently used is bulky and difficult to meet the needs of daily life and work; on the other hand, when hydrogen is inhaled, it enters the body through the respiratory system and disperses in the body, making it difficult to gather at the target site (such as the eyes), and the effect on the target site is poor.

[0004] Therefore, it is necessary to develop a device that can generate hydrogen and oxygen in situ at the target site. The generated hydrogen acts directly on the target site. The high hydrogen concentration in the target site is more conducive to the anti-inflammatory effect of hydrogen, and the generated oxygen helps the energy metabolism of cells.
