Split septum needle free connector and post needle free connector with sleeve septum fuse concept

A method for regulating delivery of a medical fluid, the method comprising, by a fluid connector assembly:

• providing a first member, the first member comprising an internal volume fluidly connecting a proximal end and a distal end thereof;
• receiving, at an opening at the proximal end of the first member, the medical fluid;
• receiving, at the distal end of the first member, a septum preventing the medical fluid from passing therethrough;
• receiving, at the septum, a second member, the second member comprising a post and an aperture extending through the post;
• receiving, at the post, a sleeve covering the aperture in a covered configuration and exposing the aperture in an uncovered configuration;
• and
• forming, based on a displacement of the sleeve into the uncovered configuration by the septum, a fluid pathway that causes the medical fluid that enters the proximal end of the first member to pass through the aperture in a coupled configuration, wherein engagement of the sleeve against a proximal end of the septum resists separation of the first member and the second member in the coupled configuration.
