Abstract

The appts. is designed for adaptation to a conventional haemodialysis appts. using its blood circulation monitoring system (air detector, etc.), so that haemofiltration can be balanced automatically. This makes it possible to carry out at one point both haemodialysis and balanced haemofiltration. Capacitive measuring of quantities for haemofiltration is applied, and the balancing is carried out without weighing. The appts. is small, light and cheap and dispenses with the weighing system. Direct continuous measurements of the amt. of filtrate takes place and the process eliminates the expense of weighing methods which due to the accuracy and security required are subject to upsets.
