Air Leakage During Aspiration – Catheter Hub Assembly

Catheters are connected to a partially filled syringe, a negative pressure is applied by pulling on the syringe plunger, visual inspection is performed to detect any bubbles forming in the syringe.

Test Procedure

Catheter hubs assemblies are connected to the syringe to form a leak proof connection while sealing all valves that are intended to open during aspiration. A known volume of water is drawn into the syringe. While the syringe nozzle is pointing downward, the plunger is withdrawn to the maximum capacity, and held for a defined period of time. This is to verify that no bubbles are forming in the syringe, therefore testing the seals efficiencies.
