This product,ezono™3000,is a revolutionary and innovative portable ultrasound system designed especially for both anesthesiologists and hospital nursing requirements. The core part is a highly flexible hardware platform combined with powerful functions. A board touch screen provides users with a safe and efficient experience of operation. The design of one-piece handle endows the whole machine comfortable feeling and meet the needs of mobile work. At the same time, the device is lightweight, while its start-up time is less than 20 seconds and the battery can last for 2 hours when fully charged. Equipped with the patented cue card, it can, therefore, speed up the reading speed of the curve. The multimedia learning and work flow tools also help to pick up the reading speed in the above research. In this process, a clearer image quality will also be obtained. In addition, the touch screen system and the icon-based user interface design can significantly reduce the complexity of the operation.
