The KD-2B Transcutaneous Electrical Nerve Stimulation (TENS) device is a low-frequency electrotherapy instrument. It delivers specific low-frequency pulse currents to the human body through skin electrodes or electroacupuncture stimulation at Ah-shi points, primarily for treating pain-related conditions.

The TENS device features three output channels and can switch between three treatment modes: continuous output, slow intermittent output, and fast intermittent output. The pulse width, frequency, and current intensity are all continuously adjustable.

It outputs three independent low-frequency pulse currents, allowing treatment for three patients or three areas simultaneously;

Offers three treatment states: continuous output, slow intermittent, and fast intermittent;

Pulse width, pulse frequency, and output intensity are continuously adjustable over a wide range, with a locking function to ensure patient safety;

Pulse frequency and output status are displayed;

Time settings can be configured as fixed or variable duration.

This device can be used for various acute and chronic pain conditions: postoperative incision pain, ligament injuries, acute sprains and contusions, dysmenorrhea, joint pain, cervical pain, residual limb pain, epicondylitis, reflex sympathetic dystrophy, etc. It also supports transcutaneous therapy and high-efficiency electroacupuncture treatment.
