The SONOtrain™ Foreign body is an ultrasound block with 6 different foreign bodies for insertion: Pellets, shard of glass, nail, projectile, loose chippings and splinters of wood can be clearly detected and recognized. Punctures and injections are possible with self-closing injection channels. The material of the SONOtrain™ trainer simulates the feel of real soft tissue for carrying out palpations and injections and shows realistic texture and echogenicity on ultrasound images. The SONOtrain™ trainer is easy to use as a teaching tool for basic training and for improving dexterity and hand-eye coordination skills.
