Abstract

A pair of separate conduits, each having an internal seal zone, may be joined by the method which comprises sealingly joining the ends of the conduits together; thereafter adding an antiseptic into the area of the joined conduits between internal seals formed in the zones; and then opening said internal seals without separating the conduits to permit internal fluid flow through the joined conduits.

Claims

1. In a connector member having a lumen carried on the end of a first conduit for sealingly connecting with the lumen of another connector member carried on the end of another conduit, the improvement comprising:

first aperture means communicating between the exterior and the interior of said connector member, bacteria-blocking, hydrophobic filter means positioned in said first aperture means, a source of antiseptic in flow communication with said first aperture means, said source of antiseptic being capable of passing an antiseptic through said filter means, and closure means for releasably sealing the interior of said first conduit without disrupting said sealing connection with the other connector member.

2. The connector member of claim 1 in which said antiseptic is chlorine gas.

3. The connector member of claim 1 in which said source of antiseptic is an ampule, separable from said first aperture means, providing pressurized chlorine gas.

4. The connector member of claim 3 in which said ampule includes a strong acid, and an alkali carbonate salt and an alkali hypochlorite salt separated from said acid by a wall to generate pressurized chlorine gas and carbon dioxide upon breaking of said wall.

5. The connector member of claim 1 in which said first aperture means is coverable at its outer end with a hinged cap member openable and closeable over said first aperture means.

6. The connector member of claim 5 wherein said releasable closure means includes jaw means for pinching shut said first conduit, and sliding means carried on said connector member to move between a first, jaw-closing position to seal said first conduit and a second position in which said jaw means are open, said sliding means being positioned to be incapable of moving into said second position unless said hinged cap member is in its closed position, to prevent the application of antiseptic while said jaw means are open.

7. The connector member of claim 1 in which said first aperture means communicates with first longitudinal channel means defined within said connector member and extends from said first aperture means toward the forward end of said connector member which joins with said other connector member, said first channel means communicating at its forward end with the connector member interior.

8. The connector member of claim 7 in which second aperture means communicates between the exterior and the interior of said connector member, said second aperture means communicating with said connector member interior adjacent its rearward end but forward of said jaw means.

9. The connector member of claim 8 in which said second aperture means is located at a longitudinal position on said connector member between its ends, and second longitudinal channel means defined within said connector member and extending from said second aperture means toward the rearward end of said connector member, to provide venting of the interior of said connector member and drainage of liquid from the end of said connector member.

10. The connector member of claim 1 in which said first conduit communicates with the peritoneal cavity of a patient and said other connector member and conduit communicates with a receptacle for peritoneal dialysis solution.

11. In a connector member having a lumen carried on the end of a first conduit for sealingly connecting with the lumen of another connector member carried on another conduit, the improvement comprising:

first aperture means communicating between the exterior and the interior of said connector member, bacteria-blocking filter means positioned in said first aperture means, and closure means for releasably sealing the interior of said first conduit without disrupting said sealing connection with the other connector member, said first aperture means being coverable at its outer end with a hinged cap member openable and closeable over said first aperture means, said closure means including jaw means for pinching shut the conduit, and sliding means carried on said connector member to move between a first jaw-closing, sliding position to seal said first conduit and a second sliding position in which said jaw means can open, said sliding means being positioned to be incapable of moving into said second sliding position unless said hinged cap member is in its closed position to prevent the application of antiseptic while said jaw means are open, and first aperture means communicating with first longitudinal channel means within said connector member and extending from said first aperture means toward the forward end of said connector member which joins with said other connector member, said first channel means communicating at its forward end with the connector member interior, whereby antiseptic in flow communication with said first aperture means can pass into the connector member interior to a location adjacent said forward end.

12. The connector member of claim 11 in which second aperture means communicates with a connector member interior adjacent its rearward end but forward of said jaw means.

13. The connector member of claim 12 in which said second aperture means is located at a longitudinal position on said connector member between its ends, and second longitudinal channel means within said connector member extending from said second aperture means toward the rearward end of said connector member, to provide venting of the interior of said connector member and facilitate drainage of liquid from the end of said connector member.

14. The connector member of claim 13 in which said first conduit communicates with the peritoneal cavity of a patient, and said other connector member and conduit communicates with a receptacle containing peritoneal dialysis solution to be infused in said cavity.

15. The connector member of claim 14 having a source of chlorine gas antiseptic in flow communication with said first aperture means, said source of chlorine gas being capable of passing chlorine gas through said filter means.

16. The connector member of claim 15 in which said source of antiseptic is an ampule, separable from said first aperture means, which includes a strong acid and a rupturable cartridge containing an alkali carbonate salt and an alkali hypochlorite salt, to generate pressurized chlorine gas and carbon dioxide upon breaking of said cartridge.

17. The connector member of claim 16 in which second aperture means communicates between the exterior and the interior of said connector member, said second aperture means communicating with said connector member interior adjacent its rearward end forward of said jaw means.
