Good Catch
A leak has been spotted from the silicone tubing of the pump boot at the point of the connector (inlet or outlet). This has now occurred on 3 separate occasions with 2 different LOT numbers. When spotted on the inlet to the pump air entrained into the circuit.
When spotted on the outlet prime was leaking/squirting out of the hole.
All 3 leaks were spotted prior to bypass. Subsequent inspection of sterile sets have identified more potentially damaged silicone boots. 2 separate batch/lot no's were involved.
