Assembly of a needle (1) and a fluid supply device (7b), the needle (1) being provided with needle coupling means (2), the supply device (7b) being provided with a nozzle (9b), the needle coupling means (2) comprising a standardized construction with standardized internal dimensions according to the Luer standard, the needle coupling means (2) further comprising a projection (5), which renders fitting the needle (1) to a supply device with a nozzle (7a) arranged for cooperation with needle coupling means having standardized construction and dimensions according to the Luer standard impossible, the nozzle (7b) of the supply device (9b) being lengthened relative to a standardized nozzle (9a), such that the needle coupling means (2) with projection (5) can still be coupled to the lengthened nozzle (9b). The invention further relates to a needle (1), a syringe (7b), a method for performing an intraneural puncture and a method for preparing an insertion device for intraneural administration.

L'invention concerne l'assemblage d'une aiguille (1) et d'un dispositif d'apport de fluide (7b), et elle est caractérisée en ce que l'aiguille (1) est dotée de moyens de couplage d'aiguille (2), en ce que le dispositif d'apport (7b) est pourvu d'une buse (9b), en ce que les moyens de couplage (2) sont de structure standard et comprennent des dimensions intérieures standardisées correspondant à la norme Luer, en ce que ces moyens de couplage (2) comprennent encore une partie saillante (5), laquelle rend normalement impossible l'ajustement de l'aiguille (1) sur un dispositif d'apport doté d'une buse (7a) agencée pour coopérer avec les moyens de couplage d'aiguille de structure et dimensions standards selon la norme Luer, mais en ce que la buse (9b) du dispositif d'apport (7b) est allongée par rapport à une buse standard (9a), de façon que les moyens de couplage d'aiguille (2) comprenant la partie saillante (5) puissent toujours être couplés à la buse allongée (9b). L'invention concerne en outre une aiguille (1), une seringue (7b), un procédé d'exécution d'une ponction intraneurale, ainsi qu'un procédé de préparation d'un dispositif d'introduction, destiné à une administration intraneurale.
