Abstract

Devices having various features to prevent the disconnection of connectors used in medical treatments are disclosed. The devices can prevent disconnection of luer connectors that are incompletely mated.

Claims

1. A connection device, comprising:

a male luer and a female luer, the female luer having a wing extending axially along the female luer and protruding radially from the female luer;

a threaded luer lock configured to prevent the male and female luers from separating; and

a flexible disconnection prevention device having an opening formed therein, the flexible disconnection prevention device being configured to prevent the luer lock from rotating when the wing of the female luer is positioned in the opening of the disconnection prevention device, or to prevent the male and female luers from separating in the event the luer lock rotates.

2. The device of claim 1, wherein the opening of the disconnection prevention device is configured to engage the male luer such that the male luer and female luer are prevented from separating.
