<p>The invention relates to a an injection material designed to be impossible to be reused after it has been used once. It is comprised of a syringe of which the nozzle (9) provided with barbs (12) prolonges a cylindrical mouthpiece (6) with which it is weakly integral. The piston of the syringe (13) is provided with an extension (14) which, when the piston is at the end of the stroke, acts as the pusher thus detaching the nozzle (9) from the mouthpiece (6), and housing it in the cavity (17) (also provided with barbs (18)) of the mandrel of the needle (16), wherein it remains blocked due to the meshing of the barbs (12 and 18). Unusable after a single utilization, syringe and needle of the invention contribute to the prevention of diseases such as AIDS, without extra cost with respect to conventional injection material.</p> |
