STRAW FOR KEEPING A PREDETERMINED DOSE OF LIQUID-BASED SUBSTANCE, AND INJECTION DEVICE AND METHOD IMPLEMENTING SAME

摘要

The straw comprises a tube (11) and a stopper (12) fixed facing the tube (11) and comprising a male connection end piece (29) configured so that a syringe needle (44) having a female connection end piece (45) with a standardized frustoconical internal surface can be coupled to said stopper (12) via engagement of the female connection end piece (45) of the needle on the male connection end piece (29) of the stopper (12). The injection device comprises such a straw (10) and a syringe needle (44). The method for emptying the straw involves the step of driving the dose of liquid-based substance (21) contained in the straw (10) toward the stopper (12).
