Abstract:
A medical fluid flow set which comprises a flexible tube having a needle hub at an end thereof, said hub carrying a hollow needle having a point, and being of enlarged transverse dimension relative to said needle; a protector tube surrounding at least one of said tube, hub, and needle, said tube being of a length to enclose said needle, said tube defining a retention member at one end to prevent said hub from passing out of said one end, said retention member comprising a plurality of plates attached to an interior surface of said protector tube and extending radially inwardly to define a restricted aperture of a size that permits flexible tubing attached to said needle hub to extend through said aperture, said plates being angled slightly from a direction perpendicular to the protector tube longitudinal axis, whereby said flexible tubing may slide in one direction through the restricted aperture, but is substantially prevented from sliding through the restricted aperture in the direction opposed to said one direction by flexing and gripping of said plates.
