In some embodiments, the coupling portions cannot be reconnected to each other after being disconnected from each other. ## Claims ### Claim 1 A single-use aseptic fluid coupling device, comprising: a male fluid coupling comprising a male valve in an open position; a female fluid coupling comprising a female valve in an open position, wherein the female fluid coupling is releasably coupled to the male fluid coupling to define an open fluid flow path therethrough; and a member removably attached to the male and female fluid couplings to prevent the male and female fluid couplings from being rotated relative to each other and from being moved longitudinally relative to each other, wherein the member comprises a longitudinal rib that mechanically engages the male and female fluid couplings to prevent the male and female fluid couplings from being rotated relative to each other, wherein the single-use aseptic fluid coupling device is configured to require movement of the male and female fluid couplings away from each other to reconfigure the male and female valves from the open positions to closed positions, wherein the member is removable from the male and female fluid couplings to allow the male and female fluid couplings to be uncoupled from each other, and wherein, after the male and female fluid couplings are uncoupled from each other, the male and female fluid couplings cannot redefine the open fluid flow path therethrough by being recoupled. ### Claim 2 (depends on 1) The single-use aseptic fluid coupling device of claim 1, wherein the male fluid coupling comprises: a male housing defining an internal space and a longitudinal axis, and wherein the male valve comprises a male coupling valve member within the internal space and slidable relative to the male housing along the longitudinal axis of the male housing from the open position to the closed position. ### Claim 3 (depends on 1) The single-use aseptic fluid coupling device of claim 1, wherein the female fluid coupling comprises: a female housing defining an internal space and a longitudinal axis; a stem fixedly coupled to the female housing and extending along the longitudinal axis of the female housing, the stem having a front surface facing a male coupling valve member of the male valve, the stem defining an open bore extending longitudinally and one or more lateral openings; and an elastomeric seal disposed on the front surface of the stem such that the male coupling valve member is abutting the elastomeric seal. ### Claim 4 (depends on 1) The single-use aseptic fluid coupling device of claim 1, wherein, while the member is removably attached to the male and female fluid couplings, the member locks the male and female fluid couplings in their respective operable configurations. ### Claim 5 (depends on 1) The single-use aseptic fluid coupling device of claim 1, wherein uncoupling of the male and female fluid couplings from each other first requires unattachment of the member from the male and female fluid couplings. ### Claim 6 A single-use aseptic fluid coupling device, comprising: a male fluid coupling comprising a male valve in an open position; a female fluid coupling comprising a female valve in an open position, wherein the female fluid coupling is releasably coupled to the male fluid coupling to define an open fluid flow path therethrough; and a member removably attached to the male and female fluid couplings to prevent the male and female fluid couplings from being rotated relative to each other and from being moved longitudinally relative to each other, wherein the member comprises a circumferential rib that mechanically engages the male and female fluid couplings to prevent the male and female fluid couplings from being moved longitudinally relative to each other, wherein the single-use aseptic fluid coupling device is configured to require movement of the male and female fluid couplings away from each other to reconfigure the male and female valves from the open positions to closed positions, wherein the member is removable from the male and female fluid couplings to allow the male and female fluid couplings to be uncoupled from each other, and wherein, after the male and female fluid couplings are uncoupled from each other, the male and female fluid couplings cannot redefine the open fluid flow path therethrough by being recoupled. ### Claim 7 (depends on 1) The single-use aseptic fluid coupling device of claim 1, wherein the member is a tear-away sleeve. ### Claim 8 (depends on 1) The single-use aseptic fluid coupling device of claim 1, wherein, while the member is removably attached to the male and female fluid couplings, the member is not longitudinally slidable nor rotatable relative to the male and female fluid couplings. ### Claim 9 A single-use aseptic fluid coupling device, comprising: a male fluid coupling;
