Samples were returned for evaluation.
Customer returned (2) loose 3/10cc insulin syringes.
Customer states stopper came away from the plunger rod.
The returned syringes were examined and neither syringe exhibited the stopper separated; no damage was observed on the barrel.
One syringe exhibited a broken thumbpress.
Sample was forwarded to manufacturing (holdrege) on 7 september 2018 for further review.
On11sep2018, holdrege received two (2) loose 0.
3ml, 8mm syringes from an unreported batch number.
All samples are decontaminated per hstr-17 prior to being evaluated.
Upon evaluation by qe ah, similar findings to those documented during initial investigation performed at bd franklin lakes were noted.
The damage to the sample exhibiting the broken plunger rod (missing the thumb-press) was noted to have multiple stress points within the material resulting in the device being rendered inoperable for the end user.
Additionally, during the device evaluation, it was noted that one returned sample was noted to have adhesive run-off onto the syringe hub, resulting in a difficult to remove shield.
Probable root cause for this defect is likely a missed cannulation for the part prior to this hub during manufacturing on the needle lines.
When this type of event occurs, adhesive from one part, which does not get applied, can be applied in addition to the normal amount of adhesive of the subsequent part.
(b)(4) was initiated by the (b)(4) plant to address shield difficult to remove the associated root cause(s).
Based on the samples/photo(s) received the investigation concluded: confirmed: bd was able to duplicate or confirm the customer¿s indicated failure - broken plunger.
Unconfirmed: bd was not able to duplicate or confirm the customer¿s indicated failure - stopper separation.
Root cause cannot be determined for the stopper separation issue at this time as the issue is unconfirmed.
Probable root causes: for broken plungers dry barrels (insufficient silicone) from the prep dial that result from a silicone gun not firing.
Insufficient silicone leads to difficulty exercising the plunger, and can thereby result in broken plungers.
Plunger screw jams that would damage plungers, i.
E.
, they break plungers.
Bowed plungers that do not get seated, and get broken off at the delrin wheel.
Dhr could not be performed as the lot number was not provided.
Severity: s_1__; occurrence: a complaint history check could not be performed for the defect/condition reported since the lot number was not provided.
