I. Yujian RYD-IIE Warm DC Drug Introduction Apparatus Product Overview

This apparatus utilizes a pulsating DC electric field to directionally deliver drug ions and charged particles through the skin to the affected area of the body for therapeutic purposes. It features four output channels, allowing for simultaneous use on multiple individuals or multi-site treatment for a single patient.

II. Structural Composition

The apparatus consists of a main unit, leads, and electrode pads.

III. Scope of Application

This product provides analgesic and anti-inflammatory effects for conditions such as hyperosteogeny, lumbar muscle strain, sprains and contusions, and joint pain. It also features pulsating DC drug iontophoresis functionality. However, the body may easily develop adaptability.

IV. Contraindications

Acute suppurative inflammation, hemorrhagic tendencies, malignant tumors, thrombophlebitis, active pulmonary tuberculosis, individuals with cardiac pacemakers, pregnant women, local foreign bodies, the cardiac region, the lower abdomen of pregnant women, and individuals intolerant to electric current.
