    摘要: An apparatus for blood dialysis composed at least of a hemodialyzer (a) whereby blood is brought into contact with a dialysate via a semipermeable membrane and thus purified; a blood circulation system (b) composed of a blood circuit in the arterial side whereby blood is taken out from a patient and flown into the hemodialyzer and another blood circuit in the venous side whereby the blood flown out from the hemodialyzer is returned to the patient; a dialysate supplying/discharging system (c) for supplying and discharging the dialysate composed of a dialysate-supply line for supplying the dialysate to the hemodialyzer and a dialysate-discharge line for discharging the dialysate flown out from the hemodialyzer, and a means (d) of controlling the back-filtration speed. Owing to this constitution, individual steps from the preparation of the dialysis (treatment) to the completion of the treatment and the change from a specific step to the next step can be safely, surely and quickly carried out in most cases. Moreover, a series of therapeutic procedures (i.e., blood collection, initiation of blood dialysis, collection and completion) can be automated.

    摘要: A method and apparatus for monitoring and measuring the filter blood volume by dilution techniques in real time, wherein the filter may be in use or off line during the measurements. The system includes a method and apparatus for measuring or monitoring the volume of a blood side of a filter by employing one of a bolus in the blood side upstream of the filter; a change of the filtration rate in the filter; and a bolus on the dialysate side, wherein the filter blood volume is calculated from the obtained data.

    摘要: A system for measuring the rate of ultrafiltration through a semipermeable membrane of a first fluid flowing across one surface of said membrane at a first pressure into a conductive second fluid flowing across the other surface of the membrane at a second pressure wherein the flow of the second fluid across the membrane is stopped, the pressure differential across the membrane is maintained at a constant level, the amount of second fluid displaced by the ultrafiltrating first fluid is passed between two electrodes across which a constant voltage is maintained, and the rate of increasing current flow between the electrodes is used to determine ultrafiltration rate.
