Product overview
The U1 is a handheld ultrasound therapy device with a pistol-grip body, a colour screen and a round treatment head at the top. Rated acoustic output is 15.0 W, adjustable in ten steps, and the acoustic working frequency is 1.0 MHz with a collimated beam and pulsed modulation.
The treatment head has an effective radiating area of 10.0 cm2 and an effective ultrasound intensity of 2.5 W/cm2 or less. Treatment time is adjustable from 0 to 30 minutes. Design points include high peak pulse energy output for penetration into deeper tissue, all-digital dynamic matching to keep the acoustic output stable, high electro-acoustic conversion efficiency so that high output is reached with a low temperature rise, and no-load protection so that output stops automatically when the treatment head leaves the body.
A built-in rechargeable lithium-ion battery of 3000 mAh at 7.4 V makes the unit independent of a mains supply. The body measures 155 mm long x 205 mm wide x 50 mm high. The specific scope of application is the one stated in the product registration certificate, and the operating procedure and parameter settings are carried out as set out in the instructions for use.
