Business outline

Kawasumi Laboratories, Inc., a predecessor company of SB-KAWASUMI, developed the first Japanese coil-type dialyzer in 1972 and has contributed to development of the hemodialysis both inside and outside Japan.

At present, there are more than two million patients who need hemodialysis in the world. Along with the increase of lifestyle-related diseases as well as economic development and introduction of social security system in emerging and developing countries, the number of such patients is growing and expected to keep growing in the future.


The kidney is an organ to filtrate waste products, toxins and excessive water from blood and excrete them as urine in order to purify body fluid. As the kidney becomes underactive due to chronic renal failure, etc., metabolic function of the human body declines to impair blood purification. As kidney functions impaired by chronic renal failure will not be recovered, hemodialysis to complement the kidney functions or renal transplantation needs to be conducted.

SB-KAWASUMI has global operations to develop, manufacture and distribute disposable products for hemodialysis, including dialyzers, blood circuits, AVF needles, and physiologic saline.
