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 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).

An attachment for a syringe for spraying mixtures of fluids, comprising: (a) an adapter having an upstream end for being connected to the syringe, a downstream end, and two supply channels extending therethrough for receiving respective fluids; (b) a disposable cannula molded of a plastic material and connected to the downstream end of said adapter, said cannula defining two longitudinally-extending distribution channels for communicating respectively with the two supply channels of said adapter to distribute the respective fluids from an upstream end of said cannula to a downstream end of said cannula, said distribution channels converging at the downstream end of said cannula to mix the fluids distributed therethrough; (c) at least one tubular outlet sleeve connected to a respective one of said two supply channels and extending outwardly from a downstream end face of said adapter, said tubular outlet sleeve received in a corresponding one of said two distribution channels for promoting the passage of fluid from the one of said two supply channels to the one of said two distribution channels; and (d) at least one inlet passage communicating with a respective one of said two supply channels at an upstream end face of said adapter for directing fluid downstream through the respective one of said two supply channels.
