A device history record (dhr) review revealed no discrepancies that may have contributed to a complaint of this reported condition.
All quality assurance testing performed during manufacturing was acceptable.
The quality assurance review of the visual, physical and dimensional evaluation results indicated that the product met specification requirements.
In addition, all dhr are reviewed for accuracy prior to product release.
A sample consisting of one used uvc catheter, which came inside a generic plastic bag was returned for evaluation.
The sample shows signs of use; remains of blood.
Under water testing was performed and a leak below the strain relief was identified in the catheter.
Magnified pictures were taken and a tear/hole was observed.
Based on the fishbone diagram, the possible causes were identified as: machine malfunction, unintentional customer misuse, product inspection inadequacy or not performed, or a sharp object was used that came into contact with the catheter are all possibilities.
Sharp objects should not be used with a catheter.
It is important to consider that the instructions for use warn: exercise caution when using sharp instruments near the catheter.
Do not use instruments with sharp or rough edges directly on the catheter since even a minor cut could tear or break the catheter.
Do not pinch or bend the catheter back to temporarily occlude the catheter.
This causes increased stress on the catheter which can lead to a leak or break.
Do not use clamps on umbilical vessel catheters] and continues, do not use alcohol, acetone, or alcohol containing antiseptics directly on the catheter.
Carefully check antiseptic solutions for alcohol or acetone.
These substances may cause irreversible damage to the polyurethane which can lead to a leak or break.
Ensure gloves or other surfaces which have alcohol on them are completely dry before touching or manipulating the catheter.
There are a number of alternatives on the field like exposure to chemical agents, proximity to heat sources or manipulation per se, that may lead to tubing tear.
Moreover, the condition found in this sample caused a leak which would be identified during assembly operations, since manufacturing performs 100% pressure testing during production.
Based on the available information, it can be concluded that product was manufactured according to specifications; therefore the most probable root cause can be considered as unintentional misuse; most likely damaged during use caused due to manipulation by the user.
No complaint triggers or trends were identified and no harm was report in this complaint, and therefore no corrective or preventive actions are required.
It must be noted that in-process controls such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection and visual acceptance sampling are in place to prevent nonconforming product from leaving the manufacturing operations.
This complaint will be used for tracking and trending purposes.
If information is provided in the future, a supplemental report will be issued.
