Abstract

A fluid transfer device for transferring fluid between a supply reservoir and a fill reservoir includes a metering reservoir and a manifold that forms at least part of a first channel that is fluidly connected with the metering reservoir. The first channel comprises a first cannula extending from the manifold. The manifold forms at least part of a second channel fluidly connected with the metering reservoir. The second channel comprises a second cannula extending from the manifold. A third channel extends through the manifold and comprises a third cannula having a first end proximate a distal end of the first cannula and a second end proximate a distal end of the second cannula. A first check valve is disposed within the first channel and a second check valve is disposed within the second channel.

Claims

1. A fluid transfer device for transferring fluid between a supply reservoir and a fill reservoir comprising:

a metering reservoir;

a first flow path having a first one-way channel fluidly connected with the metering reservoir and configured to fluidly couple the supply reservoir and the metering reservoir and a second one-way channel fluidly connected with the metering reservoir and configured to fluidly couple the fill reservoir and the metering reservoir;

a second flow path configured to fluidly couple the supply reservoir and the fill reservoir;

a member supporting the first and second one-way channels;

a tray support connected to the member and configured to align the fill reservoir with the second one-way channel; and

a tray slideably connected to the tray support and configured to accommodate the fill reservoir.

2. The fluid transfer device of claim 1, wherein the first one-way channel includes a first cannula and the second one-way channel includes a second cannula.

3. The fluid transfer device of claim 2, wherein the first cannula includes a beveled tip.

4. The fluid transfer device of claim 3, wherein the second cannula includes a beveled tip.

5. The fluid transfer device of claim 2, wherein the first cannula extends in a first direction from the member and the second cannula extends in a second direction from the member, the first direction being generally opposite the second direction.

6. The fluid transfer device of claim 5, wherein the metering reservoir extends from the member generally in the first direction.

7. The fluid transfer device of claim 2 further comprising:

a manifold that supports the first and second cannulas, the manifold forming at least part of the first one-way channel and at least part of the second one-way channel.

8. The fluid transfer device of claim 2, wherein the first cannula has a larger cross sectional area than a cross sectional area of the second cannula.

9. The fluid transfer device of claim 1, further comprising:

a supply support configured to couple the fluid transfer device with the supply reservoir.

10. The fluid transfer device of claim 9, wherein the supply support includes at least one catch proximate the first channel and configured to releasably retain the supply reservoir.

11. The fluid transfer device of claim 10, wherein the at least one catch includes at least two catches spaced different distances from the first channel.

12. The fluid transfer device of claim 9, wherein the supply support includes at least one catch proximate the first channel and configured to non-releasably retain the supply reservoir.

13. The fluid transfer device of claim 9, wherein the supply support is configured to position the first one-way channel within the supply reservoir and the first one-way channel is configured to transfer substantially all of the fluid from the supply reservoir.

14. The fluid transfer device of claim 1, wherein at least one of the tray support and the tray further comprises a safety lock configured to prevent the tray from moving relative to the member when the tray is empty and exposing the second one-way channel.

15. The fluid transfer device of claim 1, further comprising:

a safety reservoir configured to removeably couple with the tray configured to block access to the second one-way channel in an initial position.

16. The fluid transfer device of claim 1, wherein the first one-way channel includes a first cannula, the second one-way channel includes a second cannula and the second flow path includes a third cannula.

17. The fluid transfer device of claim 16, wherein the third cannula is disposed within the first cannula and a first end of the third cannula is curved toward an inner side wall of the first cannula proximate a distal end of the first cannula.

18. The fluid transfer device of claim 16, wherein a second end of the third cannula comprises a beveled tip.

19. A fluid transfer device for transferring fluid between a supply reservoir and a fill reservoir comprising:

a metering reservoir;

a first flow path having a first one-way channel fluidly connected with the metering reservoir and configured to fluidly couple the supply reservoir and the metering reservoir and a second one-way channel fluidly connected with the metering reservoir and configured to fluidly couple the fill reservoir and the metering reservoir; and

a second flow path configured to fluidly couple the supply reservoir and the fill reservoir,

wherein the first one-way channel includes a first cannula, the second one-way channel includes a second cannula and the second flow path includes a third cannula, and

wherein the third cannula is disposed within the first cannula and a first end of the third cannula is curved toward an inner side wall of the first cannula proximate a distal end of the first cannula.
