Product Code:

Electrotherapy and ultrasound therapy unit Etius U is intended for carrying out treatment procedures using:

  • wide range of bipolar and unipolar currents
  • using ultrasound therapy and phonophoresis
  • combination method of both above mentioned issues in the standard form and electrophonophoresis

Etius U unit likewise the Etius unit, is equipped with two completely independent treatment electrotherapy channels. Additionally, it has got one ultrasound therapy channel with the possibility of performing treatments using three different types of heads:

  • standard ultrasound therapy with the effective radiating area 1 cm2 or 4cm2, which generates the ultrasound wave with 1 MHz frequency
  • electrophonophoresis with the effective radiating area 4cm2, which generates the ultrasound wave with 1 MHz frequency

Dual functionality of the unit allows you to easily perform combination therapy treatments such as combined therapy or electrophonophoresis for which we designed dedicated preset treatment programs.

Etius U unit may be operated in one of two modes: when output current is stabilized and when output voltage is stabilized. The latter one is suitable for performing treatments without dedicated area and for combined therapy.

Except commonly well-known in physiotherapy currents, Etius U unit offers the application of microcurrents , unipolar sine surge, as well as TENS currents used for spastic paralysis therapy.

The unit has got more than 200 preset treatment programs, additionally, there is a possibility of creating own user-defined procedures. Besides this unique feature, the unit has got implemented handy, easily configurable list of favourite programs, where the user can save the most commonly used treatment programs.

Taking into account the importance of patient comfort, we create the patient’s stop switch that may be used in the case of feeling unwell or uncomfortable while performing treatments.

Also the unit may be applied in electrodiagnostics of nervous-muscle system.
