DEVICE FOR INTERFACING A FLUID INJECTION INSTRUMENT WITH A PUNCTURABLE FLASK AND METHOD FOR USE THEREOF

摘要

The invention concerns an interfacing device (1) intended to connect a fluid injection instrument to a puncturable flask (2), comprising: - a base (10) suitable for connecting the interfacing device (1) to the fluid injection instrument, - an attachment means (20) for attaching the base (10) to the puncturable flask (2), arranged at a distal end (1a) of the interfacing device (1), characterised in that the attachment means (20) has a divergent proximal end (21) forming a shoulder and a convergent distal end (22) suitable for facilitating the penetration of the attachment means (20) into the puncturable flask (2).
