Lot number 2919891 showed shows (b)(4) units, b9575, were manufactured, tested, inspected, and released.Functional testing: the silicone seal was protruding from the y-clave assembled into the b9575 extension set.Engineering findings: silicone seal protrusions of this nature can occur when the y-clave assembly is exposed to high back pressures.High back pressures can be generated with small syringes (10cc and smaller).This type of silicone seal protrusion can be prevented if flushing takes place through the y-clave rather than other sites along the fluid path.
