Connection for extemporaneous injections

Abstract

Abstract 1. A connecting element for extemporaneous injections constituted by the assembly of two pieces (1, 9) in plastic material, preferably translucid or transparent, the first piece (1) being constituted by a tube (2) adapted to receive a supple plastic pipe (4) supplying perfusion or transfusion liquid, and by a plate (5) perpendicular to said tube (2) ; the second piece (9) being constituted by a tube (10) designed to receive a plastic tube (12) wherefrom the perfusion or transfusion liquid flows, and by a plate (13) perpendicular to the tube (10) of the second piece (9) and comprising a hole (14) on its inner face through which flows the liquid issuing from the tube (2) of the first piece (1) towards the tube (10) of the second piece (9), the plate (5) of the first piece (1) comprising, in a position situated substantially along the axis of the tube (10) of the second piece (9) when the two pieces (1, 9) are assembled together, a perforated (7) housing (6) permitting the insertion of a selfclosable cap (8) for injecting extraneous substances, assembly of the two pieces (1, 9) being achieved in permanent and tight manner, while also providing for a tight holding of said self-closable cap (8) inside said housing (6), said connecting element being characterized in that said plate (13) of the second piece (9) comprises, in a position situated substantially opposite the tube (2) of the first piece (1) with respect to the assembly constituted by the two plates (5, 13) when said two pieces (1, 9) are assembled together, a fixed device (15, 16) comprising a slot (16) permitting the closure, by squeezing, of the supple tube (4) supplying the perfusion or transfusion liquid, said supple tube (4) being wedged in said slot (16), the disposition of the self-closable cap (8) with respect to the liquid-supplying tube (10) allows for the extemporaneous injection only in the direction of the access to the venous system of the patient.
