Abstract
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.
Claims25
A 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.
(canceled)
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, a fluid port in the housing and a connector assembly for the fluid port having a connector having a floor and a coupling portion, 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 connector than the sealing surface, the non-sealing surface being sized and shaped to hold a non-permitted conduit off of the sealing surface and prevent sealing therewith, and a bleed passage located generally adjacent the floor of the connector for bleeding fluid out of the connector assembly.
(canceled)
A system for providing vascular compression comprising a controller, a tube set, and a compression therapy device, the controller including a first connector assembly including 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 a 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 first connector assembly, the compression therapy device including a second connector including a sealing member, the 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 of the controller upon connection of the first and third connectors, and a 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.
