Pressure-regulating and adjusting connector for infusion

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

• a housing comprising a proximal end, a distal end defining an outlet, and an inner surface defining an internal chamber comprising a fluid channel disposed in the internal chamber, wherein the fluid channel extends from the proximal end to the distal end, and the fluid channel comprises an inner surface defining a lumen of the fluid channel, the inner surface comprising a threaded profile extending at least partially along the inner surface;
• and
• a slider disposed and supported in the internal chamber and sleeved over the fluid channel, the slider comprising an inner wall, an outer wall, and an internal compartment defined between the inner wall and the outer wall, and an aperture through the inner wall
• wherein the slider is reciprocally movable between (i) an open position when the medical fluid applies a fluid pressure less than or equal to a predetermined threshold to the internal compartment, and where the slider is fluidly coupled to the fluid channel to allow the medical fluid to flow along the threaded profile to the outlet, and (ii) a closed position when the medical fluid applies a fluid pressure greater than the predetermined threshold to the internal compartment, and where fluid connection between the slider and the fluid channel is blocked,
• wherein the slider is movable while maintaining the blocked fluid connection between the slider and the fluid channel in the closed position.

• a housing comprising a proximal end, a distal end defining an outlet, an outer surface, and an inner surface defining an internal chamber comprising a fluid channel disposed in the internal chamber, wherein the fluid channel extends from the proximal end to the distal end, and the housing further comprises an opening extending through the inner and outer surfaces thereof;
• a pressure adjuster mounted in the internal chamber and rotatably actuatable via the opening to adjust a pressure of the medical fluid;
• and
• a slider disposed and supported in the internal chamber and sleeved over the fluid channel, the slider comprising an inner wall, an outer wall, and an internal compartment defined between the inner wall and the outer wall, and an aperture through the inner wall
• wherein the internal compartment is configured to receive the medical fluid to move the slider between (i) an open position when the medical fluid applies a fluid pressure less than or equal to a predetermined threshold, and where the slider is fluidly coupled to the fluid channel to allow the medical fluid to flow to the outlet, and (ii) a closed position when the medical fluid applies a fluid pressure greater than the predetermined threshold, and where fluid connection between the slider and the fluid channel is blocked,
• wherein the slider is movable while maintaining the blocked fluid connection between the slider and the fluid channel in the closed position.
