Abstract:
1. An apparatus for controlling a fluid flow rate in a fluid transport line of a medical device comprising: a fluid transport line; a first pump disposed in said fluid transport line for pumping a fluid; a chamber disposed in said fluid transport line for collecting said fluid; a sensor for providing a first value correlated to the amount of fluid in said chamber; a control device configured for (i) receiving a second value representative of the fluid flow rate through the first pump (ii) converting the first value into a fluid flow rate value, and (iii) determining if the second value is accurate by comparing the fluid flow rate value to the second value; and a second pump disposed in said fluid transport line for pumping the fluid and on a side of the fluid transport line opposite to said first pump with respect to said chamber.
