How to Use
- Prepare the treatment area: Clean the skin and apply a generous layer of ultrasound coupling gel.
- Set up the device: Connect the 3 MHz probe, switch on the unit, set the treatment time, and select Continuous or Pulsed mode.
- Adjust the intensity: Begin with a low intensity and increase gradually according to the recommended treatment protocol.
- Begin treatment: Place the probe flat against the gel-coated skin and keep it moving slowly in circular or overlapping motions throughout the session.
- Finish the session: Reduce the intensity to zero, switch off the device, clean the probe, and store it in a cool, dry place.
Contraindications
Do not use this device:
- During pregnancy, or over the abdominal or pelvic area during pregnancy.
- Over or near implanted electronic devices, including pacemakers.
- Over malignant tumors or suspected cancerous tissue.
- Over areas with deep vein thrombosis (DVT) or active thrombophlebitis.
- Over open wounds, broken skin, or active infections.
- Over the eyes, heart, spinal cord, or reproductive organs.
- Over the growth plates in children or adolescents.
- If normal sensation is impaired in the treatment area without professional assessment.

Frequently Asked Questions (FAQs)
Q1. How is a 3 MHz ultrasound different from a 1 MHz ultrasound?
A 3 MHz ultrasound is generally used for superficial tissues up to approximately 2–3 cm beneath the skin, whereas a 1 MHz ultrasound is more suitable for deeper tissues. The appropriate frequency depends on the treatment area and therapeutic objective.
Q2. Is this device suitable for treating small joints?
Yes. A 3 MHz therapeutic ultrasound is commonly used for superficial structures such as the wrist, fingers, ankle, elbow, and other small joints under appropriate professional guidance.
Q3. Can I use this device after a sports injury?
Therapeutic ultrasound may be included as part of a rehabilitation program for certain sports-related soft tissue injuries. The appropriate treatment timing and settings should be determined by a qualified healthcare professional.
Q4. Can this device be used for tendon and ligament rehabilitation?
Yes. It is commonly used during supervised rehabilitation programs involving superficial tendons and ligaments, depending on the individual's condition and treatment plan.
Q5. Does this device require regular calibration or servicing?
Regular inspection of the probe, cable, and controls is recommended. If the device is not functioning correctly or has been damaged, it should be inspected and serviced by a qualified technician.
Q6. Can I use the device immediately after applying pain relief gel or cream?
Use only an ultrasound coupling gel or a coupling medium specifically recommended for therapeutic ultrasound. Ordinary creams, lotions, or cosmetic gels should not be used unless advised by a healthcare professional.
Q7. Can this device be shared between multiple users?
Yes, provided the probe is cleaned properly after each session, and appropriate hygiene practices are followed before using it on another person.
Q8. Is therapeutic ultrasound the same as a TENS machine?
No. Therapeutic ultrasound uses high-frequency sound waves to deliver energy into soft tissues, whereas TENS uses low-voltage electrical stimulation. They work through different mechanisms and may be used for different rehabilitation goals.
Q9. How long should I wait before treating the same area again?
Treatment frequency depends on the individual's condition and rehabilitation plan. Follow the schedule recommended by your physiotherapist or healthcare professional rather than repeating sessions too frequently.
Q10. Can this device replace physiotherapy sessions?
No. This ultrasonic therapy machine for pain relief is intended to complement a physiotherapy or rehabilitation program and should not replace professional medical evaluation or treatment.
