Abstract

A sideport connector for an IV catheterization system is disclosed in which a secure connection can be maintained with standard Y-shaped sideport connectors, such as a septum-type connector. The connector of the present invention comprises a clip having a collar which slidably and, optionally, rotatably engages the septum in order to prevent accidental disengagement. The clip is prevented from disengaging motion by, preferably, a ratchet-pawl mechanism. In another embodiment, the clip can be mounted on the branch of the Y-shaped sideport. The connector also comprises a needle shield or, optionally, a cap to prevent self-injection and contamination.

Claims

1. A sideport connector for removably connecting a first fluid supply tube to a second fluid supply tube, wherein said second fluid supply tube terminates in an end connector having a hub, said sideport connector comprising:

a sideport body defining at least a first and a second influent port, and at least one effluent port, said influent ports and said effluent port being in fluidic communication with one another, said first influent port being adapted to couple with the first fluid supply line and said second influent port being configured to engage the end connector of said second fluid supply line;

a housing connected to said sideport body;

a clip comprising a forward latch configured to engage the end connector hub of the second fluid supply tube, the clip being slidably connected to said housing to move in a direction generally parallel to the second fluid supply tube; and

an interengaging element preventing said latch of said clip from moving away from said second effluent port.

2. A connector for removably connecting a first fluid supply tube to a port of a second supply tube, the port including a septum cap for receiving an intravenous needle, said connector comprising:

an adapter having a tubular body defined between a forward end and a rear end, said rear end being configured to receive an end of the first fluid supply tube;

an intravenous needle connected to said forward end of said tubular body, said intravenous needle communicating with an interior of said tubular body such that said tubular body communicates with the port of the second fluid supply tube with said intravenous needle inserted through the septum cap and into the port;

a support arm cantilevered radially outwardly from said adapter;

a clip comprising a forward latch configured to engage the septum cap, the clip slidably connected with said support arm to move in a direction parallel to a longitudinal axis of said adapter, said clip pivotably connecting to said adapter to move said forward latch radially outwardly away from said forward end of said adapter; and

an interengaging element maintaining said clip from sliding away from said forward end of said adapter.

3. The connector of claim 2, wherein said support arm comprises a housing to which said clip is slidably engaged.

4. The connector of claim 3, wherein said interengaging element comprises a plurality of ratchet teeth positioned on said clip, and a pawl positioned in said housing of said support arm, said pawl being flexibly biased against and slidable over said teeth to permit said latch of said clip to slide towards said housing, said pawl cooperating with said teeth to prevent said latch from sliding away from said housing.

5. A connector for removably connecting a first fluid supply tube to a port of a second fluid supply tube, the port including a septum cap for receiving an intravenous needle, said connector comprising:

an adapter having a tubular body defining an internal lumen defined between a forward end and a rear end, said rear end being configured to receive an end of the first fluid supply tube;

an intravenous needle connected to said forward end of said tubular body, said intravenous needle communicating with said internal lumen;

a housing connected to said adapter;

a clip comprising a forward latch configured to engage the septum cap, said clip slidably connected to said housing to move in a direction parallel to a longitudinal axis of said internal lumen; and

an interengaging element preventing said clip from sliding away from said forward end of said adapter.

6. The connector of claim 5, wherein said forward cap of said clip is adapted to frictionally engage the septum cap on the port in order to prevent disengagement of said adaptor from the port.

7. The connector of claim 5, wherein said interengaging element comprises a plurality of ratchet teeth positioned on said clip, and a pawl positioned in said housing, said pawl being flexibly biased against and slidable over said teeth to permit said latch of said clip to slide towards said housing, said pawl cooperating with said teeth to prevent said latch from sliding away from said housing.

8. The connector of claim 5, wherein said clip is flexible.

9. The connector of claim 5, further comprising a needle shield mounted on said adapter and partially surrounding said intravenous needle for preventing self-injection and contamination.

10. The connector of claim 9, wherein said needle shield has an elongated, generally semi-circular shape disposed about said intravenous needle with said needle shield attached to said adapter proximate to said forward end.

11. The connector of claim 5, further comprising a needle cap surrounding said needle and removably mounted on said adapter.

12. The connector of claim 11, wherein said adapter is provided with an annular groove and said needle cap comprises an open mouth which is press fit onto said groove of said adapter in order to selectively mount said cap on said adapter whereby the intravenous needle is protected.

13. The connector of claim 12, wherein said needle cap further comprises a finger grip.

14. A sideport connector for removably connecting a first fluid supply tube to a second fluid supply tube, the second fluid supply tube terminating in a hub at a distal end with an intravenous needle projecting from the hub opposite said second fluid supply tube, said sideport connector comprising:

a sideport body defining at least a first and a second influent port, and at least one effluent port, said influent ports and effluent port being in fluidic communication with one another, said first influent port being adapted to couple with said first fluid supply line, said second influent port including a septum cap for receiving the intravenous needle of the second fluid supply line;

a housing connected to said sideport body;

a clip comprising a latch configured to engage the hub of the second fluid supply tube proximal of the needle, said clip being slidably connected to said housing to move in a direction generally parallel to the second fluid supply tube; and

an interengaging element maintaining said clip in a manually selected position on said sideport body.

15. The sideport connector of claim 14, wherein said sideport body generally has a Y-shape.

16. The sideport connector of claim 14, wherein said interengaging element includes a plurality of ratchet teeth positioned on said clip and a pawl connected to said sideport body, said pawl being flexibly biased against and slidable over said teeth to permit said latch to slide towards said second influent port, said pawl cooperating with said teeth to prevent said latch from sliding away from said second influent port.

17. The sideport connector of claim 14, wherein said clip is flexible.

18. The sideport connector of claim 14, wherein said housing defines an aperture through which said clip extends, said clip being configured to slide through said aperture.

19. The sideport connector of claim 18, wherein said interengaging element includes a plurality of ratchet teeth positioned on said clip, and a pawl connected to said housing and positioned within said aperture, said pawl being flexibly biased against and slidable over said teeth to permit said latch of said latch to slide towards said housing, said pawl cooperating with said teeth to prevent said latch from sliding away from said housing.
