Connecting device, in particular between a receptacle with a stopper capable of being perforated and a syringe
First Claim
1. Device (1) for connection between, on the one hand, a first receptacle (2) comprising a neck (2a) obturated by a visco-elastic stopper (3) capable of being perforated, and, on the other hand, a second receptacle (4) comprising a muff joint (male element) (4a), said device comprising a means (5) for perforating the stopper, comprising on the side opposite the perforating end (5a) of said perforating means, on the one hand, a faucet (female element) (6) for tight join with the muff joint (4a) of the second receptacle (4), and, on the other hand, a filtering chamber (7) isolated with respect to the outside by a filter (8), two independent channels (9, 10) being made in the perforating means (5) for establishing communication between the inside of the first receptacle (2) and the faucet (6) and the filtering chamber (7) respectively, in the position where the perforating means (5) perforates the stopper (3), said device further comprising means (11) for displacing with guidance the perforating means (5), constituted at least by a skirt (12) making an internal bore (12a), means (13) for fastening the skirt (12) on the neck (2a) of the first receptacle (2) in a fastened position in which the internal bore (12a) opens out on the stopper (3), with means (14) for sealing the internal bore (12a) with respect to the outside, a plunger (15) on which is fixed the perforating means (5), to slide by simple pressure from an inactive position in which the perforated end (5a) is spaced apart from the stopper (3), and a perforating position in which said perforating end (5a) has traversed the stopper (3), characterized in that the device further comprises means (16) for definitively stopping the plunger (15) in the perforating position, comprising a member (17) for clipping on the plunger, and a complementary stop member (18) on the skirt, the clipping member comprisinga plurality of teeth (17) distributed about the axis of the plunger (15), which are elastic in order to be returned centrifugally or centripetally, and the complementary stop member consisting of an annular flank (18) against which said teeth (17) are blocked.

Abstract
A connecting device (1) between a first receptacle (2) and a second receptacle (4) comprising a muff joint (4a), the device comprising an apparatus (5) for perforating a stopper, including a faucet (6) and a filtering chamber (7) isolated from outside by a filter (8), two independent channels (9, 10) being provided in the perforating apparatus (5) for communicating the inside of the first receptacle (2) with the faucet (6) and the filtering chamber (7) respectively, the device further comprising an element (11) for displacing with guidance the perforating apparatus (5), an element for fastening (13) the skirt (12) on the neck (2a), a plunger (15) mounted in the internal bore (12a) on which the perforating apparatus (5) are fixed, for sliding by simple pressure, and an element (16) for definitively stopping the plunger (15).
