Abstract:
1. A medical connector comprising: a body having an inlet port, a cavity, an outlet port through a male luer portion of the body, and a fluid path from the inlet port through the cavity to the outlet port; an elastic cup comprising a perimeter sealingly coupled to the body, the elastic cup configured to protrude into the cavity thereby creating a fluid volume of the cavity wherein the fluid path is through the fluid volume; a retractable post extending through the fluid path in the male luer sealing a tip of the male luer thereby closing the fluid path when the connector in not activated, the retractable post configured to contact the elastic cup; and barb arms extending along the exterior of the male luer and connected to the retractable post; wherein when the connector is activated, movement of the barb arms relative to the male luer results in the retractable post being forced away from the tip of the male luer thereby opening the fluid path through the medical connector and deforming the elastic cup into the cavity thereby decreasing the fluid volume of the cavity.
