The user experienced a pinch clamp leakage problem.This is a ltc (long term care) pharmacy.The issue was discovered at pharmacy during routing testing.During routine pump testing, 2 tube sets showed evidence of leaking through closed clamps-one while threaded in a pump (top clamp only), one while hanging attached to liter bag (both upper & lower roller clamps engaged).Over the course of several hours, all fluid in both source bags slowly leaked past the clamps and the bags emptied.This was after the pump test was completed but the tubing was still attached to source bags.Test was with 1000ml bags of ½ ns (normal saline).No patient was involved in the event.
