Abstract
The equipment consists, on the one hand, of a metallic adaptor (2) having an upstream end (10) which can be connected to the syringe and a downstream end (9) which can be connected to a disposable cannula (1), the said cannula (1) defining at least two channels (5, 6) for distribution of fluid, and the said adaptor (2) comprising a corresponding number of supply channels (18, 19) which can be brought into correspon-dence, for communication of fluid, with the said distri-bution channels (5, 6). According to the invention, the cannula (1) is made of moulded plastic material, the distribution channels (5, 6) are of constant cross-section at least over almost the whole of their length, and tubular sleeves (25, 26), connected to the said supply channels (18, 19), project from the downstream end face (37) of the said adaptor (2), the relative position and the dimensions of the said tubular sleeves (25, 26) being such that they are designed to be received, each one, in the upstream end of a distribution channel (5, 6).
