The lot number was not provided, therefore the manufacture date is unk.The terumo reservoir and the tubing which had been attached to the outlet port were returned to sgu for eval.Dimensional analysis of the returned tubing found that the inner diameter of the returned tubing was well below the upper specification limit at all measurement locations, including the end which had been connected to the reservoir.The returned tubing was re-connected to the outlet port of the returned reservoir and a 5kg weight was hung from the tubing for 2 hours.The tubing remained connected securely to the port throughout the duration of the test.The eval summarized above found no evidence to suggest that the issue experienced by the customer was caused by a problem with the tubing.Although the root cause for the disconnection could not be confirmed, inspection of the returned reservoir found that the outlet port has a tapered, conical shape and with less pronounced barbs.
