TENS EMS Combo Unit | Professional Digital Stimulator | TOP-RANK
Medical-grade TENS EMS combo unit for pain management and muscle re-education. Dual-channel isolation, 20+ preset modes, and MCU-controlled waveform stability. FDA/CE certified.
Product Overview
This is a dual-output electrical stimulation device combining Transcutaneous Electrical Nerve Stimulation (TENS) and Electronic Muscle Stimulation (EMS). It is designed as a portable clinical tool for outpatient rehab and home-use chronic pain therapy. We supply these as OEM units for medical device brands requiring a stable PCB platform with customizable firmware.
Key Features
Isolated Dual-Channel Logic
Unlike single-circuit splitters, this unit uses two independent output stages. This means the intensity of Channel A can be adjusted without affecting the load on Channel B. This hardware isolation is critical for treating two different anatomical sites simultaneously without impedance interference.
MCU Waveform Integrity
Cheap stimulators suffer from "voltage droop" as the battery drains. Our units integrate a voltage step-up regulator. Whether the battery is at 90% or 10%, the pulse amplitude remains constant, ensuring the patient receives the exact prescribed therapeutic dose.
Tactile Switch Reliability
Membrane switches fail over time due to mechanical fatigue. We use high-cycle tactile internal switches rated for 100,000+ presses. The buttons provide clear haptic feedback to the user, preventing accidental rapid-intensity jumps.
Applications
- Pain Management: Chronic back pain, arthritis, and post-operative recovery.
- Muscle Rehab: Prevention of disuse atrophy and muscle re-education after injury.
- Physical Therapy Clinics: Portable alternative to bulky desktop stimulation stations.
OEM & Private Label
We manufacture the PCB and housing in our China and Vietnam facilities.
- Software Customization: We can program custom pulse sequences, timing limits, and lock-out modes for clinical trials.
- Housing & UI: Custom silk-screened logos, localized LCD languages, and custom-colored ABS casings.
- Bundling: Total supply chain integration including lead wires, electrode pads, and carrying cases.
Certifications
- Regulatory: FDA 510(k), CE (MDR), and UKCA.
- Systems: ISO 13485 and MDSAP audited.
- QC Protocols: Every unit undergoes a 100% functional load test using a simulated 500 Ohm skin impedance to verify pulse amplitude and timing accuracy.
FAQ
Q: Why do some units feel like "stinging" instead of a smooth pulse?
A: This is usually caused by waveform distortion or high-frequency noise in the PCB layout. We use an asymmetrical biphasic pulse with a net-zero DC component to eliminate the ion accumulation on the skin that causes stinging.
Q:Can the device be powered by a USB port?
A:For Li-ion versions, USB is used for charging only. The device is not powered directly by the USB 5V line during use to ensure the high-voltage pulse circuit remains isolated from the mains power supply for patient safety.
