Method and arrangement for integrity-testing of a tube-set for use in a cycler for peritoneal dialysis
First Claim
1. A method 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 said tube set and pressure means for subjecting said housing to an underpressure or an overpressure, and including clamps for clamping portions of said tube set passing into said housing, said tube set containing air and said method comprisingsubjecting said housing to a first overpressure with said clamps closed, whereby a first pressure leakage can be observed, subjecting said housing to a second overpressure with said clamps open, whereby a second pressure leakage can be observed, and comparing said first and second pressure leakages, whereby action can be taken based upon said comparison.

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.

6. Apparatus 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 said tube set, said apparatus comprising:
-
pressure means for subjecting said housing to an overpressure or an underpressure, clamps for clamping portions of said tube set passing into said housing, whereby when said housing is subjected to a first overpressure with said clamps closed a first pressure leakage can be observed and when said housing is subjected to a second overpressure with said clamps open a second pressure leakage can be observed, and control means for comparing said first and second pressure leakages, whereby action can be taken based on said comparison. - View Dependent Claims (7, 8, 9, 10)
