Syringe adapter

1. A syringe adapter for coupling with a syringe, the syringe adapter comprising:

a housing;

a needle-free connector disposed in the housing;

a communication member in slidable engagement with the housing, the communication member slidable, with respect to the housing, between an unactuated state and an actuated state of the syringe adapter;

a cannula extending from the communication member, wherein, in the unactuated state, the cannula is retracted within the needle-free connector and, in the actuated state, the cannula protrudes through and axially beyond the needle-free connector;

a piston element disposed in the needle-free connector, the piston element comprising a piston head and a sealable orifice disposed through the piston head, wherein the sealable orifice is in a sealed state when the piston element is in an uncompressed state and is in an opened state when the piston element is in a compressed state; and

a conduit extending from, and disposed through, the communication member, wherein the conduit is fluidly separated from the needle-free connector when the syringe adapter is coupled with the syringe and in the unactuated state.

2. The syringe adapter of claim 1 , wherein the conduit is in fluid communication with the needle-free connector when the syringe adapter is coupled with the syringe and in the actuated state.

3. The syringe adapter of claim 2 , further comprising a duct extending from, and through, the communication member, wherein the duct fluidly couples the cannula to at least one vent disposed in a filter housing.

4. The syringe adapter of claim 3 , further comprising a filter disposed in the filter housing and a valve disposed between the filter and the cannula, wherein the valve is configured to allow fluid to flow from the at least one vent through the filter to the cannula and is configured to prevent fluid flow from the cannula to the filter.

5. The syringe adapter of claim 4 , further comprising a first fluid path and a second fluid path when the syringe adapter is coupled to the syringe and in the actuated state.

6. The syringe adapter of claim 5 , wherein the first fluid path is configured to provide filtered ambient air into the syringe and the second fluid path is configured to allow fluid from the syringe to flow to an intravenous set coupled to the syringe adapter.

7. The syringe adapter of claim 6 , wherein the first fluid path flows through at least the cannula, the duct, and the at least one vent.

8. The syringe adapter of claim 5 , wherein the second fluid path flows through at least the connection port, the piston element, and the conduit.

9. The syringe adapter of claim 1 , wherein the needle-free connector comprises a connection port sealingly flush with the piston head and the sealable orifice when the syringe adapter is uncoupled with the syringe.

10. A syringe adapter for coupling a syringe to a fluid system, the syringe adapter comprising:

a female connector;

a body in fluid communication with the female connector;

a male connector in fluid communication with the female connector and the body, the male connector configured to couple with a medical device;

a cannula extending axially through the body and out through the female connector; and

a filter housing in fluid communication with the cannula, the filter housing elevated axially beyond the female connector, wherein a first fluid path is formed through the filter housing and the cannula, and a second fluid path is formed through the female connector, the body, and the male connector, the filter housing configured to prevent a filter disposed in the filter housing from contacting fluid in the first fluid path, and wherein a closed system is provided when the male connector is uncoupled from the medical device.

11. The syringe adapter of claim 10 , further comprising a flexible tubing fluidly coupling the filter housing to the cannula.

12. The syringe adapter of claim 11 , wherein the female connector is coupled to the syringe such that the cannula is arranged within a chamber of the syringe.

13. The syringe adapter of claim 12 , further comprising a clip arranged around the syringe and the flexible tubing, the clip configured to secure the flexible tubing to the syringe.

14. The syringe adapter of claim 10 , wherein the medical device is an intravenous set.

15. The syringe adapter of claim 10 , wherein the medical device is a needle-free connector.

16. A syringe adapter for coupling with a syringe, the syringe adapter comprising:

a female connector configured to couple with the syringe;

a body in fluid communication with the female connector;

a male connector in fluid communication with the female connector and the body, the male connector configured to couple with a medical device;

a chamber extending from, and in fluid communication with, the body, wherein the chamber is configured to receive fluid from the syringe for subsequent delivery to the medical device; and

a needle-free connector disposed at, and in fluid communication with, the female connector, wherein the needle-free connector is configured to provide a closed system when the female connector is uncoupled from the syringe,

wherein the chamber is one of a resilient bag, a non-resilient bag and a collapsible plastic container.

17. The syringe adapter of claim 16 , wherein a valve is disposed between the female connector and the needle-free connector.
