How to find the right Diathermic Devices AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Diathermic Devices
- Regulatory clearance
- Buy only a unit cleared or approved as a medical device for your market (for example FDA-cleared in the US or CE-marked as a medical device in the EU). Diathermy deposits deep heat in tissue. An uncleared unit has no verified output control or safety cutoffs.
- Operating frequency
- Shortwave diathermy should run on the 27.12 MHz ISM band. This is the band clinical shortwave diathermy is allocated to. Off-band devices risk interference and are a sign of a non-medical product.
- Pulsed vs continuous output
- Choose a unit with a pulsed mode and adjustable pulse rate and duration if you need non-thermal or low-thermal treatment, and continuous mode for deep heating. The treatment goal decides which mode you need. Not every unit offers both.
- Applicator type
- Match the applicator to the target: induction drum or coil for muscle, capacitive plates for joints and fat-poor areas. Each applicator heats different tissue depths and types. The wrong one heats superficial tissue instead of the target.
- Safety features
- Look for automatic tuning, a treatment timer with automatic shutoff and a patient emergency-stop switch. These features prevent burns and detuning-related overheating during unattended minutes of a session.
Brands that matter
- Enraf-Nonius: Long-established clinical physiotherapy maker with a shortwave diathermy range.
- Mettler Electronics: US maker of clinical electrotherapy and diathermy units for rehab clinics.
What to avoid
- Consumer gadgets marketed as diathermy that carry no medical-device clearance
- Used units without service history, calibration or a working emergency stop
- Any use on patients with pacemakers, metal implants or electronic implants (these are standard contraindications)
Questions
Is diathermy the same as a TENS or ultrasound machine?
No. Diathermy heats deep tissue with high-frequency electromagnetic energy. TENS stimulates nerves electrically, and therapeutic ultrasound uses sound waves.
