A connector assembly includes first and second mating connectors that can be joined to make a fluid connection. The connectors are constructed to discriminate improper connectors so that no fluid tight connection can be formed with improper connectors. The connector assembly can be used with a system for compression therapy to prevent deep vein thrombosis.

1. A medical connector assembly for preventing sealing connection with a non-permitted, substantially uniform internal diameter conduit having an end face, the connector assembly comprising a first connector having a floor and a coupling portion, the coupling portion projecting outward from the floor, the coupling portion including a sealing surface and a non-sealing surface, the non-sealing surface being located closer to a free end of the first connector than the sealing surface, the non-sealing surface being sized and shaped to hold the non-permitted conduit off of the sealing surface and prevent sealing therewith, and a bleed passage located generally adjacent the floor for bleeding fluid out of the connector assembly, the bleed passage being disposed to extend between the floor of the first connector and the non-permitted conduit when the non-permitted conduit is attached to the coupling portion. 2. A connector assembly as set forth in claim 1 wherein the bleed passage is positioned to extend past the end face of the conduit when the conduit is fully inserted onto the first connector. 3. A connector assembly as set forth in claim 1 further comprising at least one stand-off rib projecting outwardly from the floor for engaging the end face of the conduit and spacing the end face of the conduit, the bleed passage being at least partially defined between the rib and the floor. 4. A connector assembly as set forth in claim 3 further comprising a plurality of ribs spaced generally circumferentially about the coupling portion. 5. A connector assembly as set forth in claim 4 further comprising connecting segments extending between adjacent ribs. 6. A connector assembly as set forth in claim 5 wherein the connecting segments comprise a surface that is beveled to facilitate fluid flow, the beveled surface defining a portion of the bleed passage. 7. A connector assembly as set forth in claim 1 wherein the first connector comprises a housing including the floor. 8. A connector assembly as set forth in claim 7 wherein the bleed passage is formed in the first connector. 9. A connector assembly as set forth in claim 8 wherein the bleed passage opens radially outward of the coupling portion at a first opening, extends axially through the housing floor and opens from the first connector on a side of the floor opposite the first opening. 10. A connector assembly as set forth in claim 1 further comprising a second connector having at least one sealing member and a receptacle including an inner end, an open outer end, the sealing member being located in the receptacle nearer to the open outer end than to the inner end. 11. A connector assembly as set forth in claim 10 wherein the second connector is sized and shaped for receiving a portion of the first connector therein. 12. A connector assembly as set forth in claim 10 further comprising a tube wherein the first connector is connected to a first end of the tube. 13. A connector assembly as set forth in claim 12 wherein the second connector is connected to the second end of the tube. 14. A connector assembly as set forth in claim 1 in combination with a compression therapy device controller for controlling the supply of fluid from a source of pressurized fluid to a compression therapy device, the controller comprising a housing and a fluid port in the housing, the connector assembly being adapted for connection to the fluid port. 15. A connector assembly as set forth in claim 1 wherein the connector assembly comprises a first connector assembly, the first connector assembly further comprising: a second connector including a sealing member;a tube set including a tube and a third connector at one end of the tube having a sealing member adapted to engage the non-sealing surface and sealing surface of the first connector upon connection of the first and third connectors; anda second connector assembly comprising a fourth connector having a floor and a coupling portion, the coupling portion including at least one sealing surface and at least one non-sealing surface, the non-sealing surface being located closer to a free end of the fourth connector than the sealing surface, the non-sealing surface being sized and shaped to hold the non-permitted conduit off of the sealing surface and prevent sealing therewith, and a bleed passage located generally adjacent the floor for bleeding fluid out of the second connector assembly, the non-sealing surface of the fourth connector being adapted to engage the sealing member of the second connector upon connection of the second and fourth connectors. 16. A connector assembly as set forth in claim 15 in combination with a system for providing vascular compression comprising a controller and a compression therapy device, the controller including said first connector assembly and the compression therapy device including said second connector. 17. A connector assembly as set forth in claim 1 wherein the bleed passage is at least partially defined by the floor of the first connector and the end face of the non-permitted conduit when the non-permitted conduit is attached to the coupling portion.
