Fluid conduit connector apparatus
View Patent ↗A fluid conduit connector apparatus that approximates pneumatic characteristics of a removed pneumatic system component when a fluid conduit is removed from a pneumatic system. The fluid conduit connector apparatus includes a port portion having a valve disposed therein. The valve closes to provide a reduced fluid orifice when a fluid conduit is removed from the port. The reduced fluid orifice is configured to provide pneumatic characteristics of the device being disconnected.
1. A fluid connector apparatus adapted for use with a pneumatic compression apparatus for applying compression treatment to a user of the pneumatic compression apparatus, the pneumatic compression apparatus having a pneumatic characteristic when the fluid connector apparatus is in fluid communication with to the pneumatic compression apparatus and fluid is being delivered through the fluid connector apparatus, the connector apparatus comprising:
a first connector including a first plurality of fluid ports each having proximal ends and distal ends, at least one of the fluid ports comprising a coupling port having a port seat therein defining a fluid orifice, the first connector being adapted for nondestructive, releasable connection with a second connector at a distal end of the first connector;
a fluid conduit for each of the fluid ports configured for connecting to the pneumatic compression apparatus, each fluid conduit being connected to a proximal end of a respective one of the fluid ports, a first of the fluid conduits being connected to the coupling port;
a coupling fitting connected to the first fluid conduit and removably mated with the coupling port thereby to connect the first fluid conduit to the coupling port; and
a valve disposed in the coupling port for movement relative to the coupling port, the valve being arranged in the coupling port for operatively engaging the coupling fitting when the coupling fitting is mated with the coupling port of the first connector so that movement of the coupling port and coupling fitting into mating connection is transmitted by the operative engagement of the coupling fitting with the valve to move and hold the valve away from the fluid orifice, the valve being disengaged from the coupling fitting when the coupling fitting and first conduit are removed from the coupling port of the first connector, the valve moving upon removal of the coupling fitting from the coupling port into engagement with the port seat to reduce a dimension of the fluid orifice without completely closing the fluid orifice to approximate the pneumatic characteristic of the pneumatic compression apparatus when the fluid connector apparatus is in fluid communication with the pneumatic compression apparatus and fluid is being delivered through the fluid connector apparatus.
2. A fluid connector apparatus as set forth in claim 1 wherein the valve includes a valve seat, the valve seat being engaged with the port seat when the coupling fitting is removed from the coupling port of the first connector and being spaced from the port seat when the coupling fitting is mated with the coupling port of the first connector.
3. A fluid connector apparatus as set forth in claim 2 wherein the port seat and valve seat are constructed to permit fluid flow through the fluid orifice, around the valve seat and past the port seat when the valve seat engages the port seat.
4. A fluid connector apparatus as set forth in claim 3 wherein at least one of the port seat and the valve seat has a slot therein sized and arranged to permit fluid flow past the valve seat and port seat when the valve seat engages the port seat.
5. A fluid connector apparatus as set forth in claim 4 wherein the slot is in the valve seat.
6. A fluid connector apparatus as set forth in claim 5 wherein the valve seat has plural slots sized and arranged to permit fluid flow past the valve seat and port seat when the valve seat engages the port seat.
7. A fluid connector apparatus as set forth in claim 6 further comprising a gasket disposed between the first and second connectors to facilitate fluid sealing between the first and second connectors.
8. A fluid connector apparatus as set forth in claim 1 in combination with said second connector and having a second plurality of fluid conduits, the second connector being adapted for connection to the first connector at a location remote from the connection of the coupling fitting to the first connector.
9. A fluid connector apparatus as set forth in claim 8 wherein the first connector includes a locking arm extending therefrom, the locking arm being adapted to releasably retain the first connector to the second connector.
10. A fluid connector apparatus as set forth in claim 9 wherein the second connector includes a slot for engaging the locking arm.
11. A fluid connector apparatus as set forth in claim 1 further comprising a pressurized fluid source.
12. A fluid connector apparatus as set forth in claim 1 wherein the coupling fitting includes an engagement portion that engages the valve upon connection of the coupling fitting with the coupling port and moves the valve away from the valve seat opening a fluid connection between the coupling fitting and said at least one of the fluid ports.
