MS 2100 was developed based on the theoretical technology of Medacord PVL, Medasonics, Fremont, CA, USA and Colin form PWV/ABI BP-203 RPEII. And the cost of above mentioned equipment is very expensive, they are difficult to be widely distributed, so it holds up necessary regular ABI check-up. Our goal is to serve society with our knowledge and professions.Two decades ago,we partnered with Japanese engineer developed MS 2100 Vital Vision Arterial Stiffness Monitor, monitoring brachial and ankle blood pressure, as well as ABI and ASI index. This equipment is a much more economical choice for hospital and health center. It can be a much more common body examination then Medosonics and Colin. It makes such important examination affordable for lower income class.
