<p>A needle assembly 10 comprises a needle device 11 having a needle base 14 and a hollow needle 12, having a free end 13 which is sharpened or pointed, protruding from the base, with a passageway 15 extending along the needle. An opening 17 to the passageway is provided in proximity to the sharpened end or point of the needle. A needle guard comprising an elongate protective sheath 20 is provided around the needle base and the needle such that the sharpened end of the needle is protected by the sheath. An elongate opening 24 extends along the sheath and the needle can pass through it. First hinge components 30 are located on the sheath. Second hinge components 16 are provided on the base. The first and second hinge components co-operate with each other such that the needle guard is pivotal from a primary position in which the sharpened needle end or point is protected by the sheath, to a secondary position in which the needle point is exposed for use. <IMAGE></p> |
