Definitions
- the present invention relates to Luer connectors.
- the International Organisation for Standardisation (ISO) by its Intemational Standard ISO 594 part 1 and part 2 deals with conical fittings with a 6% (Luer) taper for syringes, needles and certain other medical equipment. It covers conical fittings made of rigid and of semi-rigid materials.
- Luer connectors are used in particular in medical applications where it is desired to interconnect together male and female connector parts made from plastics material.
- the interconnecting male and female parts are tapered and so dimensioned according to the Luer standard so that different products from different suppliers will always fit together; the male part being received as a friction fit within the female part or by the lock fitting (ISO 594/2).
- guide-wires are sometimes passed through Luer connectors which have a configuration at their free leading end of a J-shape. It has been known for the space or trap to allow the end of the guide-wire to snag against the shoulder.
- the female part of a Luer connector is formed with at least one abutment at or adjacent the distal end of the interior of the female part for limiting longitudinal movement of a mating male part within said female part when said male and female parts are interconnected said abutment extending around a portion only of the periphery of said interior.
- Figure 1 is a perspective view, partly broken of a barrel portion of a medical stopcock ;
- Figure 2 is a side view of the medical stopcock of Figure 1
- Figure 3 is a longitudinal cross-section on the line A-A of Figure 2;
- Figure 4 is a plan cross-section on the line B-B of Figure 2.
- a barrel 2 forming part of a medical stopcock has a hollow interior. Extending radially outwardly from the outward facing surface of the barrel 2 are three spaced hollow spigots 4, 6 and 8. As is known, spigots 6 and 8 act as inlets and will be connected to a tube through which medical liquid will flow from a source (not shown). The remaining spigot 4 is an outlet spigot which will be connected to a tube for conducting the medical liquid from the stopcock towards a patient or other destination.
- the hollow spigots 4, 6 and 8 each communicate with the interior of the barrel 2 and the hollow interior of both inlet spigots 6 and 8 is tapered and dimensioned to comply with the Luer standard for mating with a Luer male part.
- each inlet spigot 6, 8 there is formed at least one abutment 10 which will effectively limit the length of engagement between a Luer male part and the interior of the inlet 6, 8.
- the male part will be prevented from being forced longitudinally within the female Luer part 6, 8 to produce high tensile stress.
- the abutment 10 extends around only a portion of the periphery of the interior and thereby offers very little resistance to the flow of fluid passing through the stopcock. Furthermore, should the free end of a mating male part not engage the abutment 10, then the resulting space between said free end and the abutment 10 would not act as a trap for air and would offer less chance of snagging the free end of a guide-wire. Trapped air is a particular danger in medical applications carrying with it the risk of air emboli. A risk also occurs in pressure monitoring applications since due to the presence of trapped air the user may receive a false reading and may therefore be mislead into reacting incorrectly in critical life threatening situations.
- the abutment could consist of several small ribs which will permit the use of guide wires through the Luer inlets and avoid formation of trapped air as well as negative effects on fluid flowing through the stopcock.
- a medical stopcock as described in the above embodiment provides a good flowpath which reduces the risk of the entrapment of air bubbles and "pockets" of drugs and turbulence in the flow of fluid therethrough and makes it possible to use guide-wires with a reduced risk of snagging.
