Abstract
Methods and apparatus are disclosed for testing the integrity of a tube set used in a cycler for peritoneal dialysis comprising a closable housing for at least a portion of the tube set and an air pump for subjecting the housing to an underpressure or an overpressure, and clamps for clamping portions of the tube set passing into the housing. The method includes subjecting the housing to a first overpressure with the clamps closed whereby a first pressure leakage is observed, subjecting the housing to a second overpressure with the clamps open whereby a second pressure leakage is observed, and comparing the first and second pressure leakages so that action can be taken based upon that comparison.
