Medical Devices and Medical Equipment Design MyLab 9 Ultrasound system by Fabio Rezzonico MyLab 9 ultrasound system provides a full range of diagnostic services. A new design with improved ergonomic, simple yet effective user interface, and a clever use of volumes are the main features of this work. Usability has been improved by redesigning the keyboard zone, making it simple and immediate. Huge efforts focused on improving probes shape and ergonomics, to lower the pain in clinicians which use them keeping the same position over time; their innovative design allows different grips, reducing musculo-skeletal strain up to 70%, for better user experience and comfort during practice.
