Fluid connector assembly with neutral fluid displacement that limits connector damage

A fluid connector assembly, comprising:

• an internal volume formed between a housing and a connector, the housing comprising an inlet port of the fluid connector assembly, and the connector comprising an outlet port of the fluid connector assembly and a post, the post having a closed distal end positioned in the internal volume, a post opening positioned proximally to the closed distal end, and a fluid channel extending between the post opening and the outlet port;
• and
• a compressible member comprising a distal end having a slit and an inner surface forming a cavity, the compressible member positioned within the internal volume with the post within the cavity;
• wherein, in an expanded position of the compressible member configured to resist a fluid flow through the compressible member and the post opening, the distal end is positioned within the inlet port with the slit closed and the inner surface of the compressible member is engaged against the post opening, and in a compressed position of the compressible member configured to permit the fluid flow through the slit, the cavity, and the post opening, the distal end of the compressible member is displaced into the internal volume of the housing such that the slit is open and the inner surface of the compressible member is spaced apart from the post opening.

A fluid connector assembly, comprising:

• a housing comprising an internal volume and an inlet port;
• a first connector comprising a first connector post and an outlet port, the first connector post having a closed distal end, a post opening positioned proximally to the closed distal end, and a first fluid channel extending between the post opening and the outlet port, wherein the first connector is coupled to the housing such that the closed distal end is positioned within the internal volume of the housing;
• a compressible member comprising a distal end having a slit and an inner surface forming a cavity, the compressible member positioned within the internal volume of the housing with the post within the cavity of the compressible member;
• and
• a second connector configured to detachably couple with the housing, the second connector comprising a second connector post forming a second fluid channel,
• wherein, when the second connector is detached from the housing, the compressible member is in an expanded position with the distal end positioned within the inlet port with the slit closed and the inner surface of the compressible member engaged against the post opening to resist a fluid flow through the compressible member and the post opening, and when the second connector is coupled to the housing the second connector post extends through the inlet port to engage against and displace the distal end of the compressible member into the internal volume such that the compressible member is in a compressed position with the slit open and the inner surface of the compressible member spaced apart from the post opening to permit the fluid flow through the second fluid channel, the slit, the cavity, and the post opening.
