A medical concept conceived and advocated by Dr. Yutaka Horiguchi, Director of Horiguchi Clinic, part of the Medical Corporation Kenshokai. It refers to “a treatment that safely supplies large amounts of electrons to the human body transdermally (via transdermal electron supply) for the purpose of antioxidant therapy.”
Reduced Electron Therapy® is a registered trademark held by the Medical Corporation Kenshokai under Class 44, “Medical Practice; Provision of Medical Information.”
All Reduced Electron Therapy devices manufactured by Reltech are equipped with a transdermal electron supply function.

The internal designation for Reltech products equipped with a function that safely supplies large amounts of electrons to the human body through the skin for antioxidant purposes (transdermal electron supply function).
There are two types of reducing electron therapy devices: (1) medical devices and (2) electron supply devices; (2) electron supply devices are not classified as medical devices under the Pharmaceutical and Medical Devices Act.
The reduced-electron therapy device is a unique product developed in-house by Reltech, and has been continuously developed, improved, and manufactured for over 20 years.

A treatment in which the human body is insulated from the ground and a negative high voltage is applied to it. Direct current is typically used.
There are two types of medical devices for potential therapy (potential therapy devices): (1) direct current (DC) potential therapy devices and (2) alternating current (AC) potential therapy devices. Reltech’s potential therapy devices are of type (1), while most potential therapy devices from other manufacturers are of type (2 ).

The goal of antioxidant therapy is to safely supply large amounts of electrons to the human body through the skin.
Note that oxidation refers to the loss of electrons, while reduction (antioxidation) refers to the gain of electrons.

An internal term used by Reltech to collectively refer to its proprietary technologies designed to safely deliver large amounts of electrons to the human body through the skin for antioxidant purposes (transdermal electron delivery function); this technology is applied to Reltech’s reducing electron therapy devices.

In the case of Lertech medical devices, a tingling sensation may be caused by a very weak current in the µA range, or by a sharp jolt resulting from the discharge of a charged weak current (static electricity).

CAM (Complementary and Alternative Medicine)
A general term for medical practices that complement standard treatments based on Western medicine or serve as alternatives to such treatments. In Japan, treatments provided on a self-pay basis (those not covered by medical insurance) are effectively considered complementary and alternative medicine.
Even if a treatment is highly advanced, if the scientific evidence supporting it is insufficient, it is classified as complementary and alternative medicine rather than standard treatment, and is therefore not covered by medical insurance.

Standard of Care
A treatment recommended for patients with a given disease based on scientific evidence that it is the “best available treatment” at present, or a treatment that is widely practiced in general
In Japan, this is essentially synonymous with treatments covered by health insurance

Medical devices that may be used only under a physician’s supervision
A physician may use such a medical device on a patient only after diagnosing the patient and determining that treatment with that medical device is necessary.

Microcurrent refers to the extremely weak currents (measured in µA) that constantly flow through the human body as part of its natural bioelectric activity.
Since microcurrent is generally considered effective for treating injuries and pain, medical devices and beauty devices that utilize microcurrent are now on the market and widely available.

An international standard for quality management systems aimed at maintaining the safety and quality of medical devices (Medical devices – Quality management systems – Requirements for regulatory purposes). It is used as the basis for quality management practices in medical device regulations around the world.
This standard is intended for organizations in the medical device industry engaged in the design, manufacture, installation, and ancillary services of medical devices, as well as the design, development, and provision of related services. The standard is structured as an extension of ISO 9001, with additional requirements necessary to ensure the safety, effectiveness, and quality of medical devices.
