DiaSens is an optical sensor that utilizes optical spectrophotometric method for light absorbance measurement.
For its operation DiaSens uses ultraviolet light that is absorbed by molecules present in spent dialysate and the reduction of substances concentration in the dialysate is linearly related to their concentration in blood thus allowing estimating the concentration of urea in blood.
DiaSens measures both Kt/V and URR values directly without any separate calculation and does not require patient body volume for its work.
As opposed to other methods that measure Kt/V value once every 25 minutes DiaSens makes measurements every 6 seconds allowing the treatment map to be created. Information provided by the treatment map is essential for estimation of the treatment quality and stability.
