Abstract

A female tube connector defining a tapered socket having an open, inner end communicating with the lumen of a tube, and a sealing cap proportioned to close the connector and to seal the tapered socket. The sealing cap comprises a cap body and a tapered projection proportioned to sealingly fit within the tapered socket. The projection is carried by the cap body and extends beyond the cap body by a distance to permit the projection to substantially completely occupy the whole length of the tapered socket when the cap is closing the female connector. The projection has an outer surface that carries an antiseptic material, so that upon such closure the interior of the tube connector can be sterilized between uses.

Claims

1. A female tube connector defining a tapered socket having an open inner end communicating with the lumen of a tube, and a sealing cap proportioned to close said connector and to seal said tapered socket, said sealing cap comprising a cap body and a tapered projection proportioned to sealingly fit within said tapered socket with a luer mating seal, said projection being carried by said cap body and extending beyond said cap, body by a distance to permit said projection to substantially completely occupy and seal the whole length of said tapered socket when said cap is closing said female connector, said projection having an outer surface that carries an antiseptic material.

2. A connector and cap of claim 1 in which said tapered projection comprises a hollow tube having an closed inner end.

3. The connector and cap of claim 2 in which said tapered projection defines a lumen, open at the projection end which extends beyond said cap body.

4. The connector and cap of claim 2 in which said tapered projection defines a lumen which contains an antiseptic.

5. The connector and cap of claim 1 in which said cap is flexibly connected to said connector.

6. The connector and cap of claim 1 in which said connector carries a tube clamp to selectively seal and open said tube at a flexible portion of said tube adjacent to said connector.

7. The connector and cap of claim 1 in which said tapered projection extends at least about 4 mm. outwardly beyond said cap body.

22. A blood handling set which comprises flexible tubing, the flexible tubing having an end carrying a female tube connector and sealing cap of claim 1.

8. A female tube connector defining a tapered socket having an open inner end communicating with the lumen of a tubes and a sealing cap proportioned to close said connector and to seal said tapered socket, said sealing cap comprising a cap body and a tapered projection proportioned to sealingly fit within said tapered socket with a luer mating seal, said projection being carried by said cap body and extending beyond said cap body by a distance to permit said projection to substantially completely occupy the whole length of said tapered socket when said cap is closing said female connector, said tapered projection comprising a hollow tube having an impenetrably closed inner end, and having an outer surface that carries an antiseptic material.

9. The connector and cap of claim 8 in which said tapered projection defines a lumen, open at the projection end which extends beyond said cap body.

10. The connector and cap of claim 8 in which said cap is flexibly connected to said connector.

11. The connector and cap of claim 8 in which said connector carries a tube clamp to selectively seal and open said tube at a flexible portion of said tube adjacent to said connector.

12. The connector and cap of claim 8 in which said tapered projection extends at least about 4 mm. outwardly beyond said cap body.

13. The connector and clamp of claim 12 in which said connector carries a tube clamp to selectively seal and open said tube at a flexible portion of said tube adjacent to said connector.

14. The connector and cap of claim 13 in which said cap is flexibly connected to said connector.

15. The connector and cap of claim 14 in which said tapered projection defines a lumen, open at the projection end which extends beyond said cap body.

16. The connector and cap of claim 15 in which said lumen contains an antiseptic.

23. A blood handling set which comprises flexible tubing, the flexible tubing having an end carrying a female tube connector and sealing cap of claim 8.

17. A female tube connector defining a tapered socket having an open inner end communicating with the lumen of a tube, and a sealing cap proportioned to close said connector and to seal said tapered socket, said sealing cap comprising a cap body and a tapered projection proportioned to sealingly fit within said tapered socket, said projection being carried by said cap body and extending beyond said cap body by a distance to permit said projection to substantially completely occupy the whole length of said tapered socket when said cap is closing said female connector, and further in which said connector carries a tube clamp to selectively seal and open said tube at a flexible portion of said tube adjacent to said connector.

18. The connector and cap of claim 17 in which said tapered projection extends at least about 4 mm. outwardly beyond said cap body.

19. The connector and cap of claim 17 in which said tapered projection has an outer surface that carries an antiseptic material, said tapered projection being proportioned to sealingly fit within said tapered socket with a luer mating seal.

20. The connector and cap of claim 17 in which said tapered projection comprises a hollow tube having an impenetrably closed inner end and a lumen, open at the projection end which extends beyond said cap body.

21. The connector and cap of claim 20 in which said lumen contain an antiseptic.

24. A blood handling set which comprises flexible tubing, the flexible tubing having an end carrying a female tube connector and cap of claim 17.
