Abstract
A blood clarification device wherein a means for measuring blood pressure comprises (a) a needle-detector which is much thinner than the puncture needle and capable of being smoothly inserted into a blood vessel from outside through an inner aperture of the puncture needle, (b) an insertion aperture, for allowing fluid-tight insertion of the needle-detector, positioned on a wall of the blood supply passage in the vicinity of the puncture needle, and (c) a pressure transducer for detecting the blood pressure inside the blood vessel transmitted thereto via the needle-detector. In a blood clarification apparatus of the present invention, blood pressure inside a blood vessel is transmitted to a pressure transducer via a needle-detector during dialysis/filtration operation and blood pressure of a patient is detected continuously and automatically by the pressure transducer. A counterplan such as control of water-removing-rate or supplying-supplementary-fluid-rate based on the detected blood pressure is automatically carried out, so that safety of dialysis/filtration operation can be effectively improved.
