The stop valve (116) prevents fluid flowing out of the end (111; 311) of the connector body (112, 114; 300) unless a complementary end of a separate device (not shown), typically a Luer lock connector, engages the end of the connector body and opens the stop valve (116). To facilitate manufacture and assembly, the one-way valve (118) and the stop valve (116) can be formed as parts of a single piece of elastomeric material, the parts being hingedly connected so that the one-way valve part (118) can be folded over to be fitted directly into the end of the stop valve part (116). A further possibility, also applicable when only a stop valve (116) is provided, is that the connector body (300) may be formed in one piece with a folding, snap fit closure (312). ## Claims ### Claim 1 A medical connector comprising a connector body having first and second apertures in fluid communication via a fluid flow conduit, a one-way valve disposed in the connector body to allow fluid to flow from the first aperture, through the fluid flow conduit and out of the second aperture, but not to allow fluid to flow from the second aperture and through the fluid flow conduit to the first aperture, and a stop valve which prevents fluid flowing out of the second aperture of the connector body unless a complementary end of a separate device engages the second aperture and opens the stop valve, wherein inside the connector body, the one-way valve is fitted directly into an end of the stop valve in a manner providing a fluid tight seal between these valves; and wherein the one-way valve and the stop valve are formed as parts of a single piece of elastomeric material, said valves being hingedly connected such that the one-way valve is folded over and fitted directly into the end of the stop valve. ### Claim 2 (depends on 1) The connector according to claim 1 wherein the end of the stop valve into which the one-way valve is fitted is formed with a recess and a periphery of the one-way valve seats in that recess. ### Claim 3 (depends on 2) The connector according to claim 2 wherein the recess is configured so that the one-way valve is fully counter sunk into the end of the stop valve. ### Claim 4 (depends on 1) The connector according to claim 1 wherein the one-way valve part and the stop valve part are additionally connected by a strap portion of the elastomeric material, said strap being folded over such that the one-way valve fits into the end of the stop valve. ### Claim 5 (depends on 1) The connector according to claim 1 wherein the one-way valve is a duck bill valve. ### Claim 6 (depends on 1) The connector according to claim 1 wherein the stop valve is a swabable entry port valve. ### Claim 7 (depends on 1) The connector according to claim 1 wherein the connector body is formed of only two body parts. ### Claim 8 (depends on 1) The connector according to claim 1 wherein the connector body is formed in one piece with a folding, snap fit closure. ### Claim 9 (depends on 1) The connector according to claim 1 wherein the first aperture is within a male end of the connector which is configured as a male Luer lock connector portion and the second aperture is within a female end of the connector which is configured as a female Luer lock connector portion and provides a swabable entry port for attachment of a complementary needleless device. ### Claim 10 (depends on 1) A three-way tap arterial blood sampling device incorporating the sampling connector according to claim 1.
