Method: the complaint ojr412 junior cannula was received and was visually inspected.Results: visual inspection of the returned cannula showed that the right tube had detached from the cannula.Evidence of adhesive was present on the external surface of the tube as well as on the interior of the cannula tube joint.Conclusion: the observed damage was most likely caused by an excessive pulling force.All optiflow junior cannulae are 100% leak and occlusion tested after final assembly and any cannula that fails is discarded.In addition, a tube tensile strength test is carried out and if the tube breaks before the load of 10 newtons is reached the entire batch is scrapped.Samples are also taken from each run and pull tested to check glue joint strength at the cannula/tube joint, as well as the swivel grip joint.The user instructions illustrate in pictorial format the correct set-up and proper use of the optiflow junior 2 cannula.They also state the following: do not wrap, insulate, stretch or crush the tubing as this may impair the performance of this product or compromise safety (including potentially causing patient harm).
