摘要:
A blood treatment device, in particular a dialysis machine, which permits both single-needle and dual-needle operation. The device has a blood treatment unit, in particular a dialyzer that has an inlet connected to a feed line and an outlet connected to a return line. The feed line has two parallel line branches with a positive displacement pump being connected into the first and second line branches. To produce a fluid connection between the outlet of the dialyzer and one of the two pumps, a connection line is provided. For dual-needle operation, the feed and return lines are connected to an arterial and a venous needle. For single-needle operation, the feed and return lines are brought together and connected to a common needle. The connection line permits single-needle operation without great changes to the structure of the blood treatment device.
摘要:
A method and device for controlling an extracorporeal blood treatment apparatus, which can be operated as a hemodialysis apparatus, hemofiltration apparatus or hemodiafiltration apparatus, are disclosed. The method and device make provision, apart from balancing the fluids as a function of the weights of the containers, for the measurement of the weight reduction or increase of at least one of the containers in the time interval in which the pump assigned to the respective container performs a preset number of revolutions or pump strokes. The change in the weight of the container for a half or one pump revolution can be determined. The delivery rate of the respective pump is ascertained from the measured weight reduction or increase in the specific time interval, thereby permitting the precise determination of the actual delivery rate of one or more pumps. The actual delivery rates of all the pumps are preferably monitored.
