The structural design solves the problem that the lens rotation and the screen lifting can be synchronized, and the patients on both sides of the bed can be used only by rotating the support arm. The lens and arm can be rotated 270 degrees and the display screen is pushed up and down to facilitate the operation of medical staff, quickly find the injection vein, and reduce patient pain.

The processing technology adopted is based on the concept of environmental protection. This is a perfect combination of function and aesthetics. The overall shape of the product uses a non-chamfered curve, which is round and friendly, reducing its aggressiveness. The overall color is white with medical attributes and dark gray embellishment colors, reflecting the professionalism of the product.
