摘要：
An injection port assembly comprises a body having a first mating structure and a second mating structure coupled together. A resilient barrier is received within the body and compressible between a less compressed first position in which fluid flow through the injection port assembly is blocked, to a more compressed second position in which fluid flow through the injection port assembly is permitted. A hollow cannula is coupled to the first mating structure. The hollow cannula has a distal end portion configured to extend through the resilient barrier when the resilient barrier is in the more compressed second position. The hollow cannula is opaque and both the second mating structure and the resilient barrier are transparent, so that any fluid leakage into the internal cavity of the resilient barrier is visible through the resilient barrier and the second mating structure against an opaque background provided by the opaque cannula.
