Pressure-regulating connector for infusion

A connector for connecting a container containing a medical fluid to a vascular access device, the connector comprising:

• an upper housing comprising an inlet at a proximal end and an inner surface defining a first internal chamber;
• a lower housing coupled to the upper housing, and comprising an outlet at a distal end, and an inner surface defining a second internal chamber for circulation of the medical fluid into the outlet;
• and
• a slider positioned at least partially in the first and second internal chambers, the slider comprising a head portion and a stem portion, the head portion forming a plurality of radially extending vanes, and the stem portion having a distal end forming a plug;
• and
• wherein the slider is reciprocally movable between an open position and a closed position, wherein the plug is spaced apart from the inner surface of the lower housing to allow the medical fluid to flow through the outlet when the slider is in the open position, and wherein the plug is engaged against the inner surface of the lower housing to resist the medical fluid from flowing through the outlet when the slider is in the closed position.
