<p>The unit consists of a metallic attachment (2), the upstream end (10) of which can be coupled to the syringe while its downstream end (9) can be coupled to a disposable cannula (1), the latter defining at least two fluid supply channels (5, 6). The attachment (2) comprises a corresponding number of inlet channels (18, 19) which can be placed in fluid communication with said supply channels (5, 6). According to the invention, the cannula (1) is made of a moulded plastic material, the supply channels (5, 6) have a constant cross section at least over almost all of their length. The tubular end parts (25, 26), coupled to said inlet channels (18, 19), project from the downstream end face (37) of said attachment (2), their relative position and size making them suitable for being received in the upstream end of a supply channel (5, 6).</p> |
