According to the origin, the source of hydrogen inhalation
equipment is the electrolysis of water, and the electrolysis of
aquatic products started from Japan:
In 1966, Japan issued Medical equipment Certification No. 1 for
drinking devices;
In 1944, the Japanese Ministry of Health and Welfare (equivalent to
the national Ministry of Health) established the "Electrolytic
water Research Committee";
In 1944, the Japanese Cancer Prevention and Treatment Center
published a report "free radicals are the cause of cancer", and
confirmed that water electrolysis can eliminate free radicals in
human body;
In 2007, Professor Ota Sunio from Japan Medical University
published the first hydrogen biology paper "The protective effect
of hydrogen molecules on cerebral ischemia-reperfusion injury" in
Nature Medicine, which confirmed that the hydrogen contained in
electrolytic water was the fundamental reason for its effect.
In December 2016, the Japanese Ministry of Health, Labor and
Welfare announced the inclusion of "hydrogen inhalation treatment
for cardiac arrest syndrome" into the "Class B cash medical
treatment system in Japan".
This ushered in a new era of medical research on hydrogen, and the
equipment for electrolysis of water to produce hydrogen and oxygen
has become increasingly mature and has a large number of users.
