Abstract

A blood testing system includes a cartridge loadable into a blood analyzer. One cartridge includes a convex top portion with a blood entry port therein. A dispenser transfers blood in a stoppered test tube to the cartridge. One dispenser includes a contoured, stabilizing base configured to mate with the cartridge convex top portion. The dispenser may further include a hub supported by the base, a cannula extending upward from the hub, and a dispensing tip in fluid communication with the cannula depending downward from the hub and inserted into the blood entry port of the cartridge when the dispenser base is mated with the cartridge convex top portion.

Claims

1. A blood testing system comprising:

a blood analyzer;

a cartridge loadable into the blood analyzer, the cartridge including a convex top portion with a blood entry port therein; and

a dispenser for transferring blood in a stoppered test tube to the cartridge,

the dispenser including;

a contoured, stabilizing base configured to mate with the cartridge convex top portion,

a hub supported by the base,

a cannula extending upward from the hub, and

a dispensing tip in fluid communication with the cannula depending downward from the hub and inserted into the blood entry port of the cartridge when the dispenser base is mated with the cartridge convex top portion.

2. The system of claim 1 in which the dispenser base includes spaced front and rear concave arch members connected by spaced side rails.

3. The system of claim 2 in which one or both spaced side rails include an inward undercut feature.

4. The system of claim 2 in which the rails are straight.

5. The system of claim 2 in which the base further includes one or more spokes interconnecting the base with the hub.

6. The system of claim 5 in which there is a spoke extending inwardly from each rail to the hub.

7. The system of claim 1 in which the cannula includes a lower plastic portion and an upper metal portion fit into the lower plastic portion.

8. The system of claim 1 in which the dispensing tip is tapered.

9. The system of claim 8 in which the dispensing tip has an outer diameter proximate the hub slightly smaller than the inner diameter of the blood entry port.

10. The system of claim 1 in which the dispenser base, hub, and dispensing tip are made of plastic.

11. A dispenser for transferring fluid in a stoppered test tube to a cartridge with a convex top portion including a fluid entry port therein, the dispenser comprising:

a contoured, stabilizing base configured to mate with the cartridge convex top portion;

a hub supported by the base;

a cannula extending upward from the hub; and

a dispensing tip in fluid communication with the cannula depending downward from the hub and insertable into the fluid entry port of the cartridge when the dispenser base is mated with the cartridge convex top portion.

12. The dispenser of claim 11 in which the dispenser base includes spaced front and rear arch members connected by spaced side rails.

13. The dispenser of claim 12 in which one or both spaced side rails include an inward undercut feature.

14. The dispenser of claim 12 in which the rails are straight.

15. The dispenser of claim 12 in which the base further includes one or more spokes interconnecting the base with the hub.

16. The dispenser of claim 15 in which there is a spoke extending inwardly from each rail to the hub.

17. The dispenser of claim 11 in which the cannula includes a lower plastic portion and an upper metal portion fit into the lower plastic portion.

18. The dispenser of claim 11 in which the dispensing tip is tapered.

19. The dispenser of claim 18 in which the dispensing tip has an outer diameter proximate the hub slightly smaller than the inner diameter of the fluid entry port.

20. The dispenser of claim 11 in which the dispenser base, hub, and dispensing tip are made of plastic.

21. A dispenser for transferring fluid in a stoppered test tube to a cartridge with a top portion including a blood entry port, the dispenser comprising:

a base formed to seat on the cartridge top portion;

a hub supported by the base;

a cannula extending upward from the hub; and

a dispensing tip in fluid communication with the cannula depending downward from the hub and insertable into the fluid entry port of the cartridge when the dispenser base is seated on the cartridge top portion.

22. The dispenser of claim 21 in which the dispenser base includes spaced front and rear arch members.

23. The dispenser of claim 22 in which the base includes spaced side rails connecting the front and rear arch members.

24. The dispenser of claim 23 in which one or both spaced side rails include an inward undercut feature.

25. The dispenser of claim 23 in which the rails are straight.

26. The dispenser of claim 23 in which the base further includes one or more spokes interconnecting the base with the hub.

27. The dispenser of claim 26 in which there is a spoke extending inwardly from each rail to the hub.

28. The dispenser of claim 21 in which the cannula includes a lower plastic portion and an upper metal portion fit into the lower plastic portion.

29. The dispenser of claim 21 in which the dispensing tip is tapered.

30. The dispenser of claim 29 in which the dispensing tip has an outer diameter proximate the hub slightly smaller than the inner diameter of the blood entry port.

31. The dispenser of claim 21 in which the dispenser base, hub, and dispensing tip are made of plastic.
