Abstract

This invention consists of an elastic and sliding valvular joint for pre-filled syringes, which comprises a single chamber with an injectable product or two chambers that contain isolated products to be mixed before the injection. Said valvular joint acts as a temporary closure, which prevents the internal chamber from communicating with the outside, or between both internal chambers. Said joint comprises two discoid cooperative elements arranged on the syringe and with its edge against the internal surface: an elastic discoid plug and a sliding receiving discoid seat. The plug acts in a cylindrical cavity; the edge of the discoid seat constitutes a cordon that is thicker and less elastic than the rest of the seat. The plug includes an elastic base from which a hollow open and closing cylinder is formed; the receiving discoid seat includes a central passage tube facing the hollow cylinder, and the elastic base of the plug fits in a removable manner inside a cylindrical cavity of the opening of the central passage tube of the seat. The diameter of the elastic base of the plug is equivalent to the diameter of the receiving discoid seat. When the hollow closing cylinder is inside the central passage tube of the discoid seat, the elastic base of the plug fits inside a circular cavity surrounded by the edge of the discoid seat that forms said cordon. The outer diameter of the hollow closing cylinder is equivalent to the internal diameter of the central passage tube of the receiving discoid seat, offering a calibrated fit.
