OSACHI was founded in 1981 and has since been engaged in the research, development, manufacturing, and sales of vascular function assessment and pain quantification products. Decades of accumulated expertise have culminated in two flagship products: the arterial stiffness assessment system ArterioVision MS-3000 and the pain quantification system PainVision PS-3100. Both products are widely used in clinical practice and research at medical institutions and research organizations in Japan and abroad. Beyond developing and selling our own products, we also offer ODM product development, contract manufacturing, and customization services tailored to our customers' specific requirements. The design and manufacturing expertise we have built in the fields of pulse wave measurement and pain quantification can be applied to meet the needs of medical device manufacturers and research institutions. We welcome inquiries from the earliest stages of product development.
