This is attributed musculoskeletal disorders. This is attributed to the combination of sustained pinching and to the combination of sustained pinching and pushing needed during some ultrasound pushing needed during some ultrasound procedures. In order to alleviate the need for procedures. In order to alleviate the need for the sonographer to apply a sustained force, the sonographer to apply a sustained force, we developed a design that can apply a force we developed a design that can apply a force for the duration of the procedure. The design for the duration of the procedure. The design consists of an arc attached over the consists of an arc attached over the echocardiogram bed connected to a echocardiogram bed connected to a transducer by a arm. Movement is possible transducer by a arm. Movement is possible via a slider over the arc, a ball and socket via a slider over the arc, a ball and socket joint, a hinge joint, and a rotating joint where joint, a hinge joint, and a rotating joint where the transducer is attached. The sonographer the transducer is attached. The sonographer locks the arm in place to sustain a force and locks the arm in place to sustain a force and performs the detailed movements necessary.performs the detailed movements necessary.Eighty percent of sonographers suffer from Eighty percent of sonographers suffer from musculoskeletal disorders.
