Kangyuan Medical Technology (Dalian) Co., Ltd. was established in November 2016. It is committed to the research and development and production of a new generation of specific and high-efficiency blood purification adsorption materials, new nano-antibody screening and preparation, and new nano-antibody-based clinical diagnostic reagents. The project started construction in 2018. It is an overall contract for a multi-storey building multi-layer purification workshop, with a total construction area of 6,300 square meters, and the purification level covers ABCD level. The project is to be completed under the preconditions of construction difficulty on multiple floors, multiple disciplines, and multiple interfaces at the same time, and the purification level requires a high degree of difficulty.
