Abstract

Devices and methods for assembling a luer lock fitting (e.g., fitting for use in a hemodialysis and/or a peritoneal dialysis machine) may include a luer lock tool comprising a tool base including a grip portion adjacent a tool portion, the grip portion having an outer diameter and an internal cavity. The tool portion may have an internal cavity and may be configured to selectively receive and retain a male luer lock fitting at a first end of the cavity. A tool cap may have an outer diameter and an internal cavity. The tool cap may include a recessed portion at an end configured to selectively receive and retain a female luer lock fitting. The tool cap internal cavity may be configured to receive at least a portion of the tool portion of the tool base.

A luer lock tool, comprising:

a tool base including a grip portion adjacent 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;

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.
