The invention relates to a method for setting up a fluid treatment apparatus using a single, and always accessible, reader of information relating to replaceable components which are to be mounted on the apparatus to perform the fluid treatment. It is also disclosed a fluid treatment apparatus having the always accessible reader. The reader can also be relied on to enter information other that those relating to the replaceable components, such as commands for the apparatus, patients' related information, etcetera.

Fluid processing medical apparatus and method for setting-up a fluid processing medical apparatus

A method is disclosed for determining a parameter (D, K, Kt/v, Cbin) indicative of the effectiveness of an extracorporeal blood treatment carried out using a membrane exchanger. The method includes the steps of flowing through the exchanger a treatment liquid having a concentration characteristic (Cd) and of varying the value of the characteristic (Cd) upstream of the exchanger for a time at the end of which the characteristic (Cd) is returned to a nominal value. A plurality of values adopted by the characteristic (Cd) downstream of the exchanger in response to the upstream variation is measured and stored in memory. The area (Sout) of a downstream perturbation region is determined, which is bounded by a baseline and a curve representing the variation of the measured values with respect to time. Then, the parameter (D, K, Kt/v, Cbin) indicative of the effectiveness of the treatment is calculated using the area (Sin) beneath the upstream curve and an area beneath an upstream curve.

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.

Method for the determination of a significant parameter of the progess

A device and method are provided for controlling the balance of fluids during an extracorporeal blood treatment session, according to which treatment, a certain quantity of liquid is withdrawn from the blood which is compensated for by the injection of a substitute liquid into the extracorporeal circuit. A recirculation circuit is provided and pressure is monitored. A pressure deviation within the recirculation circuit reflects a change in the balance between the quantity of liquid withdrawn from the blood and the quantity of liquid injected into the blood, and injection and/or withdrawal rates are altered to obtain a desired balance. The device and method are especially applicable to haemofiltration, haemodiafiltration and plasmapheresis.

The invention is a method for checking the operation of at least one sensor situated in a dialysis liquid circuit of an artificial kidney. The method includes causing a reference liquid of known characteristics to circulate in the extracorporeal blood circuit, taking a measurement to check at least one characteristic of the dialysis liquid by means of the sensor, calculating the theoretical value of at least one characteristic of the reference liquid on the basis of the measurement, comparing the calculated theoretical value with the known value of the said characteristic of the reference liquid, concluding that the sensor is working properly after the measurement has been taken when the calculated theoretical value is substantially equal to the known value. A device for the application of this method is also disclosed.
