Abstract:
1. A sampling connector for use as an adaptor for a three-way tap arterial blood sampling device, which sampling connector comprises at least two apertures in fluid communication via a fluid flow conduit and a one-way valve disposed to allow fluid to flow from a first aperture, through the fluid flow conduit and out of a second aperture, but not to allow fluid to flow into the second aperture and through the fluid flow conduit to the first aperture, characterized in that the first aperture is within a male end and the second aperture is within a female end and said male end of the sampling connector is a luer lock connector with an altered taper or altered dimensions so as to fit firmly or jam when connected to a female sampling port of the sampling device, such that the sampling connector is reversibly connectable to the sampling device and is difficult to disconnect from the sampling device by fitting firmly or jamming when connected to a sampling port of a sampling device, and such that the one-way valve is configured to prevent the introduction of a separate fluid through the second aperture and the first aperture to a body cavity, wherein in use a user is impeded from removing the sampling connector.
