The device further includes a sleeve having an open first end for coupling with a male luer connector, a second end coupled to the housing, and an axis between the first and second ends. The sleeve defines at least one window. The device further includes an arm extending from a bottom of each window toward the first end, and a member extending radially from an inner surface of each arm. Each member has a ramp surface, an engagement surface extending transversely to the ramp surface, and an apex area that transitions between the ramp surface and the engagement surface ## Claims ### Claim 1 A priming device comprising: a housing defining a chamber and an inlet port, wherein the chamber and the inlet port are fluidly coupled, the housing comprising an opening extending from within the chamber to outside the housing and configured to permit a gas to exit the chamber; a sleeve having an open first end configured to couple with a male luer connector, a second end coupled to the housing, and an axis between the first end and the second end, wherein the sleeve defines at least one window; an arm extending from a bottom of each window toward the first end; and a member extending radially from an inner surface of each arm, wherein each member comprises a ramp surface, an engagement surface extending transversely to the ramp surface, and an apex area that transitions between the ramp surface and the engagement surface. ### Claim 2 (depends on 1) The priming device of claim 1, wherein when the priming device is in a priming-ready configuration, the male luer connector is partially inserted into the sleeve and the engagement surface of a member engages a bottom-facing edge of the male luer connector. ### Claim 3 (depends on 1) The priming device of claim 1, wherein when the priming device is in a priming configuration, each arm flexes away from the axis such that a cross-sectional width between the apex areas is at least equal to an outer surface of the male luer connector. ### Claim 4 (depends on 3) The priming device of claim 3, wherein the inlet port is advanced over a portion of a male luer connector stem to fluidly couple the housing with the male luer connector, thereby creating a fluid pathway between the male luer connector and the chamber. ### Claim 5 (depends on 1) The priming device of claim 1, wherein a filter is disposed in the opening. ### Claim 6 (depends on 5) The priming device of claim 5, wherein the filter comprises a hydrophobic filter. ### Claim 7 (depends on 1) The priming device of claim 1, wherein the opening extends through a portion of the housing opposite the inlet port. ### Claim 8 (depends on 1) The priming device of claim 1, wherein the open first end of the sleeve has an inner cross-sectional width configured to receive an outlet port of the male luer connector. ### Claim 9 (depends on 8) The priming device of claim 8, wherein the inner cross-sectional width of the first end is equal to an outer cross-sectional width of the outlet port such that the outlet port is press fit into the sleeve partially toward the second end of the sleeve. ### Claim 10 (depends on 8) The priming device of claim 8, wherein when the priming device is in a priming-ready configuration, the engagement surface of each member contacts an edge of the outlet port to prevent insertion of the male luer connector beyond the member. ### Claim 11 (depends on 1) The priming device of claim 1, wherein the male luer connector comprises: an inlet port, an outlet port, and a body between the inlet port and the outlet port; a luer portion extending from within the body toward the outlet port, wherein a fluid path extends from the inlet port through the body and luer portion; and a post extending through the fluid path in the luer portion. ### Claim 12 (depends on 11) The priming device of claim 11, wherein: in a closed position, the post seals an open tip of the luer portion thereby closing the fluid path; and in an open position, the post is retracted toward the inlet port of the male luer connector and into the luer portion, thereby opening the fluid path. ### Claim 13 (depends on 11) The priming device of claim 11, wherein the inlet port defined in the housing has a thread extending circumferentially outward from an outer surface thereof, the thread configured to engage a mating thread on an inner surface of the outlet port to threadably couple the housing with the male luer connector. ### Claim 14 (depends on 1) The priming device of claim 1, wherein an outer surface of the housing comprises one or more channels between the second end of the sleeve and the opening to increase rigidity of the priming device, and provide increased torsional leverage when coupling or decoupling the sleeve with the male luer connector. ### Claim 15 (depends on 1) The priming device of claim 1, further comprising one or more ribs extending along an outer surface of the housing between the second end of the sleeve and the opening to increase rigidity of the priming device, and provide increased torsional leverage when coupling or decoupling the sleeve with the male luer connector. ### Claim 16 A priming device comprising: a housing defining a chamber and an inlet port fluidly coupled to the chamber, the housing comprising an opening extending through a portion of the housing opposite the inlet port, the opening configured to permit a gas to exit the chamber; a sleeve having an open first end configured to couple with a male luer connector, a second end coupled to the housing; and at least one window defined through the sleeve, the at least one window comprising an arm extending toward the first end and the arm including at least one member extending radially from an inner surface of each arm. ### Claim 17 (depends on 16) The priming device of claim 16, wherein each member comprises a ramp surface, an engagement surface extending transversely to the ramp surface, and an apex area that transitions between the ramp surface and the engagement surface. ### Claim 18 (depends on 17) The priming device of claim 17, wherein when the priming device is in a priming-ready configuration, the male luer connector is partially inserted into the sleeve and the engagement surface of the member engages a bottom-facing edge of the male luer connector. ### Claim 19 (depends on 17) The priming device of claim 17, wherein an axis is defined between the first end and the second end of the sleeve and when the priming device is in a priming configuration, each arm flexes away from the axis such that a cross-sectional width between the apex areas is at least equal to the outer surface of the male luer connector. ### Claim 20 (depends on 16) The priming device of claim 16, further comprising one or more ribs extending along an outer surface of the housing between the second end of the sleeve and the opening to increase rigidity of the priming device, and provide increased torsional leverage when coupling or decoupling the sleeve with the male luer connector.
