Connecting device

A connecting device for use in connecting together open ends of two or more medical instruments so as to control a flow of fluid between the medical instruments, said connecting device comprising:

• intermediate conduit means having two or more ports to which open ends of the two or more medical instruments are connectable;
• and,
• a plurality of fluid directing members located inside said intermediate conduit means and movable linearly therein in an end-to-end abutting relationship, so that each of said fluid directing members has a first end and a second end and are arranged along said intermediate conduit means so that said first end and said second end, respectively, of adjacent said fluid directing members abut one another, said fluid directing members being operable for allowing, or restricting, the flow of fluid, via said intermediate conduit means, between two medical instruments when the medical instruments are connected to the ports of said intermediate conduit means, depending upon a linear position of said fluid directing members inside said intermediate conduit means,
• said fluid directing members being movable within said intermediate conduit means from a first position, wherein said fluid directing members act to close all the ports in said intermediate conduit means to fluid flow, to a second position, wherein said fluid directing members allow fluid flow between two of said medical instruments connected to said connecting device, to a third position, wherein all the ports of said intermediate conduit means are closed to fluid flow between said intermediate conduit means and said two medical instruments, the movement of said fluid directing members being a sequential movement, in one direction, from each position to the next.
