Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What is claimed is:

1. A luer lock tool, comprising:

a tool base including a grip portion adj cent a tool portion, the grip portion having an outer diameter and an internal cavity, and the tool portion having an internal cavity and being configured to selectively receive and retain a male luer lock fitting at a first end of the cavity; and

a tool cap having an outer diameter and an internal cavity, the tool cap including a recessed portion at an end configured to selectively receive and retain a female luer lock fitting; wherein the tool cap internal cavity is configured to receive at least a portion of the tool portion of the tool base.

2. The luer lock tool according to claim 1, wherein the tool base and the tool cap are configured to engage together such that a central axis of the tool base and a central base of the tool cap are coaxial when the tool base and the tool cap are engaged.

3. The luer lock tool according to any of claims 1-2, wherein the recessed portion of the tool cap is configured to contact a flange of the female luer lock fitting, the recessed portion having a plurality of protrusions and recesses configured to engage with corresponding recesses and protrusions of the flange.

4. The luer lock tool according to any of claims 1-3, wherein the tool portion of the tool base is configured to contact the male luer lock fitting, the tool portion having a plurality of protrusions and recesses configured to engage with corresponding recesses and protrusions of the male luer lock fitting.

5. The luer lock tool according to claim 2, wherein one of the tool base and the tool cap are configured to remain stationary and the other of the tool base and the tool cap are configured to rotate about the respective central axis.

6. The luer lock tool according to claim 2, wherein the tool base and the tool cap are configured to rotate in opposite directions about the respective central axis.

7. The luer lock tool according to any of claims 1-6, wherein identification markings are disposed on at least one of the grip portion outer diameter of the tool base and the tool cap outer diameter.

8. The luer lock tool according to any of claims 1-7, wherein a plurality of notches are disposed on at least one of the grip portion outer diameter of the tool base and the tool cap outer diameter.

9. The luer lock tool according to any of claims 1-8, further comprising an ejection mechanism configured to selectively eject at least one of the male luer lock fitting and the female luer lock fitting.

10. The luer lock tool according claim 9, wherein the ejection mechanism includes a rod and a spring, disposed coaxially at least partially in the tool portion cavity and the grip portion cavity of the tool base.

11. The luer lock tool according to claim 10, wherein the spring is disposed adjacent a ledge in the grip portion cavity of the tool base and a cap is coupled to an end of the rod, the cap and the end of the rod being disposed external to the tool base.

12. The luer lock tool according to any of claims 10-11, wherein the ejection mechanism is configured to compress the spring such that the rod is configured to eject at least one of the male luer lock fitting and the female luer lock fitting out of the recessed portion end of the tool cap.

13. The luer lock tool according to any of claims 1- 12, wherein when the tool base and the tool cap are engaged, the tool portion of the tool base is disposed adjacent the recessed portion of the tool cap.

14. The luer lock tool according to any of claims 1-13, wherein the tool base outer diameter and the tool cap outer diameter are equal.

15. A method for assembling a male luer lock fitting and a female luer lock fitting by a luer lock tool, the method comprising:

inserting the male luer lock fitting in a tool portion of a tool base, the tool base including a grip portion adjacent a tool portion, at least a portion of the tool portion configured to selectively receive and retain the male luer lock fitting;

inserting the female luer lock fitting in a recessed portion of a tool cap, the recessed portion being configured to selectively receive and retain the female luer lock fitting;

engaging the tool base and the tool cap by inserting the tool portion of the tool base in an internal cavity of the tool cap such that the tool portion of the tool base is adjacent the recessed portion of the tool cap and a central axis of the tool base is coaxial with a central axis of the tool cap, and the male luer lock fitting is receivable into the female luer lock fitting; and rotating one of the tool base and the tool cap about the respective central axis while holding the other of the tool base and the tool cap stationary, such that the male luer lock fitting and the female luer lock fitting are locked together by the rotation of the one of the tool base and the tool cap.

16. The method according to claim 15, further comprising ejecting the locked male luer lock fitting and the female luer lock fitting by an ejection mechanism.

17. The method according to claim 16, wherein the ejection mechanism includes a rod and a spring, the rod and the spring disposed at least partially in an internal cavity of the tool base and an internal cavity of the tool cap and coaxial to the tool base and the tool cap, and a first end of the rod and the spring being external to the tool base.

18. The method according to claim 17, wherein the spring extends externally along the rod, and the spring is compressed between the first end of the rod and a ledge in an internal cavity of the tool base, a second end of the rod being disposed at least partially in the internal cavity of the tool cap such that the rod pushes the locked male and female luer lock fitting out of the recessed portion of the tool cap.

19. The method according to any of claims 15-18, wherein protrusions of the male luer lock fitting engage in recesses of the tool portion of the tool base, and recesses of the male luer lock fitting engage in protrusions of the tool portion of the tool base.

20. The method according to claim 19, wherein protrusions of a flange of the female luer lock fitting engage in recesses of the recessed portion of the tool cap, and recesses of the flange of the female luer lock fitting engage in protrusions of the recessed portion of the tool cap.
