Abstract

A filling device and method, particularly for two-component sealants such as fibrin sealants, which enables two fluids to be separately and directly filled to the reservoirs of a dual syringe fluid applicator from two storage containers, which can be standardized, sealed, sterilized bottles. The device has a connector which engages with the fluid applicator, is keyed to orient the applicator'"'"'s fluid reservoirs in a predetermined manner and holds the containers in side-by-side alignment with the applicator. Two fluid conduits whose downward ends may be pointed to pierce seals on the bottles, extend between the applicator and the bottles and can each have a transverse reach to accommodate the girth of the bottles. The bottles may be tilted by the device to enable the conduits to draw maximal fluid from a lowermost point of the bottle. Tilting can be effected by a downward movement of the device supporting the applicator which movement can introduce the fluid conduits into the bottles. A shroud can enclose and seal the bottles and permit the apparatus complete with fluid applicator to be introduced into a sterile environment. Additionally embodiments for use with a single vial are also disclosed.

Claims

1. A connector for connecting a fluid dispensing instrument to a single container of fluid having a longitudinal axis, the connector comprising:

a) a body having a bottom and a top, said top having an outer perimeter and an outlet port within said perimeter, said bottom having an inlet port connected to said outlet port wherein said inlet port is connected to said outlet port by a bore in said body;

b) a collar extending from said perimeter, said collar being adapted to detachably receive said dispensing instrument;

c) a tube is connected to said inlet port and having an end distal to said inlet port for extending into said container, said end having an opening for drawing fluid; and

d) a hood extending from said body and including a base, an exterior surface, and a support surface extending inwardly from the exterior surface and above the base;

said support surface having a generally laterally extending slot relative to the longitudinal axis, said slot slidably and releasably receiving a neck of said single container, said hood having a length sufficient to enclose the container when received by said support surface such that once the container is received within said hood, fluid in the container can be drawn into said dispensing instrument through the distal end of the tube and the connector substantially encloses the container.

2. The connector as recited in claim 1 wherein said collar, said body, and said hood are formed of thermoplastic materials.

3. The connector as recited in claim 2 wherein said thermoplastic is selected from the group consisting of polycarbonate, polystyrene, polypropylene, polytetrafluoroethylene, acrylonitrile butadiene-styrene, and acrylic.

4. The connector as recited in claim 1 wherein said collar, said body, and said hood are formed as a single thermoplastic member.

5. The connector as recited in claim 1 wherein said tube is formed of a metallic material.

6. The connector as recited in claim 1 wherein said collar is keyed to said dispensing instrument such that said dispensing instrument may be fitted to said connector in only one orientation.

7. The connector as recited in claim 1 wherein said hood comprises a resilient material and is sized such that when said container is positioned within said hood, said hood resiliently conforms to fit and secure said container in place.

8. The connector as recited in claim 1 wherein said hood further comprises a locking member adapted to secure said container to said connector.

9. The connector as recited in claim 8 wherein said locking member comprises resilient plastic joined to said hood and extends radially inward from said hood such that when said container is positioned within said locking member, said locking member secures said container in place.

10. The connector as recited in claim 8 wherein said locking member is an o-ring fitted within said hood.

11. The connector as recited in claim 1 wherein said outlet port comprises a circular shape.

12. The connector as recited in claim 1 wherein said bore is tapered.

13. The connector as recited in claim 1 wherein said collar is capable of making a Luer lock with said dispensing instrument.

14. The connector as recited in claim 1 wherein said connector further comprises a tubular air vent attached to said connector wherein said air vent further comprises a first opening, a second opening, and a conduit connecting said first opening to said second opening and said first opening is positioned such that when said container is locked to said hood, said first opening is situated inside said container and said second opening is externally situated on said connector such that positive air pressure is supplied said container reducing any vacuum forces created within said container during drawing.

15. The connector as recited in claim 1 wherein said distal end of said tube has a pointed tip adapted to sealably pierce a cap of said container.

16. The connector as recited in claim 1 wherein said hood is adapted to allow the container to tilt relative to the connector.

20. The connector of claim 1 wherein the support surface is a first support surface and the hood further includes a second support surface which extends radially inward from the exterior surface and is spaced below the first support surface.

34. The connector of claim 1 wherein said support surface is inclined to support the container in a non-vertical position.

17. A connector for connecting a fluid dispensing instrument to a single container of fluid comprising:

a) a body having a bottom and a top, said top having an outer perimeter and an outlet port within said perimeter, said bottom having an inlet port connected to said outlet port wherein said inlet port is connected to said outlet port by a bore in said body;

b) a collar extending from said perimeter, said collar being adapted to detachably receive said dispensing instrument;

c) a tube is connected to said inlet port and having an end distal to said inlet port for extending into said container, said end having an opening for drawing fluid; and

d) a hood extending from said body and including a base, an exterior surface, and a support surface extending inwardly from the exterior surface and above the base;

said support surface adapted to slidably and releasably receive said single container, and adapted to support the single container suspended above at least a portion of the base, said hood having a length sufficient to enclose the container when received by said support surface such that once the container is received within said hood, fluid in the container can be drawn into said dispensing instrument through the distal end of the tube and the connector substantially encloses the container.

19. The connector of claim 17 wherein the single container is suspended above an underside of the base.

21. The connector of claim 17 wherein said collar, said body, and said hood are formed of thermoplastic materials.

22. The connector of claim 17 wherein said collar, said body, and said hood are formed as a single thermoplastic member.

23. The connector of claim 17 wherein said tube is formed of a metallic material.

24. The connector of claim 17 wherein said collar is keyed to said dispensing instrument such that said dispensing instrument may be fitted to said connector in only one orientation.
