Asclepius Hydrogen-Oxygen Generator: How Was a National Innovative Class III Medical Device Certified?

In the global field of hydrogen-oxygen medicine, the Asclepius Hydrogen-Oxygen Generator is a name that cannot be overlooked. When consumers are faced with the growing array of hydrogen-oxygen devices on the market, a fundamental question arises: What exactly is the Asclepius Hydrogen-Oxygen Generator, and what sets it apart from ordinary hydrogen generation equipment?

In essence, the Asclepius Hydrogen-Oxygen Generator is a Class III medical device certified by China's National Medical Products Administration (NMPA) not a household appliance or industrial-grade machine. Its introduction has moved hydrogen-oxygen medicine from the research laboratory into standardized clinical practice. This article offers an in depth examination of the device from three perspectives: its technical positioning, development journey, and core patents. It is written for readers who are exploring hydrogen-oxygen therapy, considering purchasing related equipment, or concerned about product safety and regulatory compliance.

What Is a Class III Medical Device, and Why Is the Hydrogen-Oxygen Generator Classified as Such?

At its core, the Asclepius Hydrogen-Oxygen Generator is a Class III medical device. Under China's medical device classification system, devices that employ hydrogen generation technology for human inhalation are regulated as Class III the highest risk tier. This category encompasses devices that are implanted in the body, used to sustain life, or carry potential hazards that demand stringent oversight.

  • Risk drives classification:Hydrogen is flammable, and as the smallest molecule in existence, it readily crosses cell membranes and exerts clear biological effects. For this reason, regulators place it in the same highest-risk category as cardiac stents and artificial joints, ensuring rigorous safeguards for long-term use. The Asclepius Hydrogen-Oxygen Generator, for instance, underwent comprehensive evidence-based validation before it was finally approved.
  • Extremely rigorous review standards:Securing Class III certification is no small achievement. Asclepius Meditec, the developer behind the device, spent more than a decade navigating the full spectrum of evidence-based validation from cellular and animal studies through to human clinical trials and successfully cleared multiple rigorous testing regimes, including biocompatibility, electrical safety, and electromagnetic compatibility.

How Did Asclepius Medical Break Through the Safety Bottleneck of Traditional Water Electrolysis Technology?

Traditional water electrolysis technology is predominantly used in industrial applications such as hydrogen energy production and metal welding. The core materials employed in these systems including ion-exchange membranes and strong-alkaline electrolytes pose long-term health risks if directly applied for human inhalation. The Asclepius Hydrogen-Oxygen Generator represents a fundamental breakthrough in overcoming these safety challenges.

  • "Zero air cavity" and multi-layered explosion-proof design:To mitigate the inherent flammability and explosiveness of hydrogen, the Asclepius Hydrogen-Oxygen Generator incorporates an innovative air cavity design that minimizes instantaneous pressure buildup in the event of combustion or explosion, and is further safeguarded by multiple flame arrestors. According to the review opinion issued by the Center for Medical Device Evaluation of China's National Medical Products Administration (NMPA) on the registration application for the Asclepius Hydrogen-Oxygen Inhalation Device, the applicant submitted sufficient safety validation data, the product's risk control measures were deemed acceptable, the overall benefits outweighed the risks, and registration was ultimately approved.

 

# (6) Research on Hydrogen Combustion and Explosion Safety

In accordance with the requirements of item B5.3 of the Basic Requirements Checklist for Safety and Effectiveness of Medical Devices, a study on combustion and explosion risks was conducted. This included a simulation study on the distribution of hydrogen concentration in the surrounding environment during prolonged use, as well as ignition damage assessments. Additionally, the hydrogen concentration in patients' exhaled breath was measured after 8 hours of continuous treatment. Risk control measures—including airtightness verification—were implemented throughout. Collectively, these studies demonstrate that the residual risk of hydrogen combustion and explosion is acceptable.

# (7) Research on Nebulization Performance

In accordance with the requirements of item B11.1 of the Basic Requirements Checklist for Safety and Effectiveness of Medical Devices, a study was conducted to evaluate the particle size distribution of the aerosol generated by the nebulization module. This module is designed to atomize water, thereby humidifying the hydrogen-oxygen gas mixture for patient inhalation.



"Membrane-Free, Alkali-Free" National Innovative Technology

This is the core technological moat that sets the Asclepius Hydrogen-Oxygen Generator apart from all imitative products. It entirely forgoes the industrial-grade AEC (alkaline electrolysis) and PEM (proton exchange membrane) technological routes. On March 7, 2017, the Center for Medical Device Evaluation of the China Food and Drug Administration (CFDA) issued the "Public Notice of Special Approval Application Review Results for Innovative Medical Devices (2017, No. 2)," in which the "Hydrogen-Oxygen Inhalation Device" was included on the special approval list for innovative medical devices with Shanghai Asclepius Meditec Co., Ltd. named as the applicant.
