    摘要: The device for controlling the rotation speed of electric motors comprises an adjustable frequency generator (2) generating an output signal (s.sub.1) having a frequency which can be adjusted in relation to the desired speed (v.sub.d), a pulse generator (3) having a pre-determined period controlled by the adjustable frequency generator in such a way as to generate a control signal (s.sub.2) comprising a series of pulses at the adjustable frequency set by the frequency generator (2). The control signal (s.sub.2) is provided to a control unit (5) for the motor (6) whose rotation speed is to be controlled. The control unit thus provides a supply to the motor (6) corresponding to the control signal pulses. FIG. 1.

    摘要: A method for determining a significant parameter (Cb, D, K, Kt/V) of the progress of an extracorporeal blood treatment carried-out using a membrane exchanger, includes the steps of successively circulating three treatment fluids through the exchanger. Each fluid has a characteristic Cd linked to at least one of the significant parameters of the treatment (Cb, D, K, Kt/V). The value of the characteristic in the first fluid upstream of the exchanger is different from the value of the characteristic in the second fluid upstream of the exchanger, the latter being itself different from the value of the characteristic in the third fluid upstream of the exchanger. Two values for each of the three treatment fluids are measured, respectively upstream and downstream of the exchanger, and at least one value of at least one significant parameter of the progress of the treatment (Cb, D, K, Kt/V) is calculated from the measured values.

    摘要: A method and apparatus are disclosed for flushing a blood treatment apparatus. The blood treatment apparatus has a first compartment and second compartment separated by a semipermeable membrane substantially impermeable to gas. A flushing circuit is set up by connecting an inlet of the blood treatment apparatus to a flushing liquid source and an outlet of the blood treatment apparatus to a discharge pipe. Liquid is circulated through the flushing circuit in pressure waves. These pressure waves dislodge air bubbles adhering to an inner wall of the blood treatment apparatus and discharge the air bubbles in the flushing liquid.

    摘要: A filtration device includes an ultrafilter having an inlet chamber, an outlet chamber, and an ultrafiltration membrane separating the inlet chamber from the outlet chamber. An inlet line flow connects the inlet chamber to a source of dialysis liquid. Pressure sensors determine pressure values on opposite sides of the membrane, and a controller calculates a transmembrane pressure therefrom and compares the calculated transmembrane pressure with a predetermined threshold value. If the threshold value is reached, the controller emits a threshold signal to either warn an operator or alternatively to automatically divert flow to bypass the ultrafilter.

    摘要: A sampling system for a blood treatment circuit is disclosed, and is designed to collect a sample representative of all waste liquid discharged from a blood treatment apparatus during a treatment session. The circuit includes a feed line for supplying fresh treatment liquid to the blood treatment apparatus and a discharge line for evacuating waste liquid. A withdrawal line connects the discharge line to a collecting container, and a flow meter in each of the discharge line and the withdrawal line measures liquid flow. A controllable flow restrictor such as a valve is provided in the withdrawal line. A controller selectively opens the flow restrictor each time a predetermine volume is measured in the discharge line and closes the flow restrictor each time another predetermined volume is measured in the withdrawal line.

    摘要: A device for measuring the quantity of ultrafiltrate eliminated during a dialysis treatment. The device comprises two vessels of a known capacity wherein the ultrafiltrate coming from a pump is alternately received and then discharged by means of valves. The device further comprises two level measuring sensors which each emit a signal each time the ultrafiltrate attains a predetermined level in the corresponding vessel. Such sensors are connected to a processing and count control mechanism for analyzing the above-mentioned signals and for establishing the quantity of ultrafiltrate eliminated by the pump.
