In this product, the designers transform the rigorous testing and examining technique to user-friendly design, thus changing the cold and stiff appearance of the medical device and avoiding patients from feeling fearful and uneasy. Displacement design, the space between the keyboard and base, provides physicians with sufficient room and makes operation process more comfortable. The individualized user-defined keys can be endowed with functions as per specific requirements of physicians, enabling operations to accommodate habits of different physicians.
