Device Story

ezFit Digital Heating TENS (HR-661/UC-101) combines transcutaneous electrical nerve stimulation (TENS) and thermal therapy for pain management. Device features two independent output channels for use with two or four electrode pads. Inputs include user-selected settings for electrical stimulation and thermal intensity. System utilizes thermoelectric electrode pads to provide controlled heat (36°C–42°C) to skin; automatic thermal control prevents injury. Powered by 3.6V Ni-H rechargeable batteries or AC-DC adapter. Operated by user via large LCD panel. Output provides electrical pulses and/or thermal heat to target areas. Clinical benefit includes symptomatic relief of chronic intractable pain and temporary relief of minor aches, pains, and muscle spasms.

Clinical Evidence

No clinical data. Evidence consists of bench testing including software validation, waveform and output study, and skin temperature study to demonstrate safety and effectiveness.

Technological Characteristics

Dual-channel TENS and powered heating pad. Thermoelectric electrode pads with automatic thermal control (36°C–42°C). Powered by 3.6V Ni-H batteries or AC-DC adapter. Large LCD interface. Conforms to ISO 14971, IEC 60601-1, and IEC 60601-1-2 standards.

Indications for Use

Indicated for symptomatic relief and management of chronic intractable pain (TENS) and temporary relief of minor aches, pains, and muscle spasms (heating therapy).

Regulatory Classification

Identification

A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain.

to use a single channel connecting to two electrode pads or using both channels with four electrode pads simultaneously. With large LCD panel. It is powered by 3.6V(1.2V x 3)Ni-H Rechargeable Batteries or AC-DC adaptor.

The ezFit Digital Heating TENS(Model No.: HR-661/ UC-101) is a TENS (Transcuntaneus Electrical Nerve Stimulator) that employs a combination application of previously well known electrical and temperature treatment modalities for pain relief and rehabilitation. The system is based on a combination of thermal transfer (Powered heating pads - 21 CFR 890.5740) and conventional TENS - 21 CFR 882.5890) therapy.

When used in either Compress heat function only or Compress heat function plus TENS , An electronically controlled thermoelectric electrode pads can provide automatic thermal control with a Range of 36℃ - 42℃ . The Dual output can be adjusted to provides thermal heat to the skin between 40 and 42 °C for at least 10 minutes as therapeutic heating. This automatic thermal control mechanism also avoid skin from thermal injury.
