The invention relates to a flow limiting device. The flow limiting device may include a male luer connector portion and a female luer connector portion. The male luer connector portion may define a cavity and a first lumen in fluid flow communication with the cavity. The female luer connector portion defines a second lumen and an extension in fluid flow communication with the second lumen. The extension includes a first end, a second end, an outer surface, and a channel. A channel is defined on the outer surface. The channel is helically disposed about an outer surface of the extension and extends between the first end and the second end. The extension is configured to be at least partially disposed within the cavity. The channel and an inner surface of the cavity define a fluid passageway in fluid flow communication with the first lumen and the second lumen. 本发明涉及一种流量限制装置，该流量限制装置可以包括公鲁尔连接器部分和母鲁尔连接器部分。公鲁尔连接器部分可以限定空腔和与该空腔流体流动连通的第一管腔。母鲁尔连接器部分限定第二管腔和与该第二管腔流体流动连通的延伸部。延伸部包括第一端、第二端、外表面和通道。通道限定在外表面上。通道围绕延伸部的外表面螺旋地设置
