Title: Dialysis connector with retention and feedback features

Abstract: Apparatuses and methods for providing audio, visual and/or tactile feedback during assembly of two mating medical fluid connectors and a retention force are provided. The invention includes a first connector defining a first lumen and a second connector defining a second lumen. The first and second connectors are threaded together to enable the first lumen to initially communicate fluidly with the second lumen after the first and second connectors are engaged. The first connector defines a first engaging member and the second connector defines a second engaging member, the engaging members mating to provide (i) feedback indicating that a mating of the first and second connectors is at least substantially complete and (ii) a retention force tending to hold the first and second connectors together. An improved apparatus for releasing a sealed disinfectant is also provided.
