ITO SW-1000: High-Power Continuous & Pulsed Shortwave Diathermy System
Operating at 27.12 MHz with up to 400W peak pulsed power, automatic resonance inductive tuning, touch display, and multi-joint articulated electrode arms for deep volumetric clinical heating.
• Biophysical Physics: High-Frequency Dielectric & Eddy Current Heating
High-Frequency Electromagnetic Depolarization
Shortwave energy at 27.12 MHz causes rapid oscillation of dipolar water molecules and ions within biological tissues millions of times per second. This molecular friction produces uniform, deep volumetric endogenous heat in vascular muscular and articular structures.
Pulsed Athermal & Thermal Selectivity
Continuous mode delivers vigorous thermal heating for chronic joint capsulitis and contractures. Pulsed mode allows high peak pulse power (400W) with long cooling intervals, enabling deep sub-thermal or mild-thermal healing in subacute injuries.
Key Clinical Innovations & Advantages
Continuous & Pulsed Modes
100W continuous for deep heating; up to 400W peak pulsed power with adjustable pulse repetition rates and widths.
Automatic Impedance Matching
Internal microprocessor dynamically matches applicator circuit impedance to patient tissues, maximizing energy transfer efficiency.
Capacitive & Inductive Fields
Supports both condenser disc plates for planar heating and inductive coil applicators for selective muscle and tendon warming.
Heavy-Duty Mechanical Arms
Counterbalanced multi-joint positioning arms hold heavy electrodes firmly in place throughout treatment.
