Abstract

A dialysis machine has a semipermeable membrane with flow paths on opposite faces of the membrane for dialysate and blood respectively, transducers 40, 70 for providing signals representative of the dialysate and blood pressures and comparator circuit means for providing an alarm signal 312 if the dialysate pressure exceeds the blood pressure so that passage of impurities into the blood is prevented. A bypass for the dialyser may be brought into action at the same time. Further alarm means 324 for indicating lack of blood pressure signal may be provided. The blood pressure transducer may also control a flapper valve for controlling the negative dialysate pressure. <IMAGE>
