A hollow needle (19) is open at its outer end and is slidably mounted to the body (11) for axial movement therein. The needle (19) is movable between a first position in which it extends through said opening (17) such that its outer end extends beyond the body (11) and a second position in which the outer end of said needle is located innermost from said opening (17). A second aperture (21) in the wall of the needle (19) provides communication between the chamber (18) and the lumen of the needle (19) when in the first position. |
