<p>A blood clarification device wherein a means for measuring blood pressure (34) comprises (a) a needle-detector (40) which is much thinner than the puncture needle (42) and capable of being smoothly inserted into a blood vessel (38) from outside through an inner aperture of the puncture needle, (b) an insertion aperture (46), for allowing fluid-tight insertion of the needle-detector (40), positioned on a wall of the blood supply passage in the vicinity of the puncture needle (42), and (c) a pressure transducer (34) for detecting the blood pressure inside the blood vessel (38) transmitted thereto via the needle-detector (40). In a blood clarification apparatus of the present invention, blood pressure inside a blood vessel is transmitted to a pressure transducer (34) via a needle-detector (40) during dialysis/filtration operation and blood pressure of a patient is detected continuously and automatically by the pressure transducer (34). 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. <IMAGE></p> |
