Abstract

Arrangement for hypodermic injections, of the type usable only once, characterized in that it is constituted by a solid tubular needle in its rear part to a coupling sleeve in plastic, to which it forms an interior space open at the rear, in which a cap associated with a syringe carrying the injectable liquid is applied, so that the aforementioned cap and sleeve have on their opposing faces annular reliefs protruding to determine relative positions between needle and syringe, both elements being initially independent, so that for a first inoperative coupling position, corresponding to the nailing phase of the needle, the mentioned sleeve and sleeve are pressed in until, through elastic effect, antagonistic reliefs are inserted, while for the second operating position, pressure is applied again the mentioned elements until obtaining an irremovable insertion of both r antagonistic ellipses, whereby the needle, at its rear end, reaches and perforates an elastic sealing gasket located at the mouth of the syringe, whereby the liquid runs along the needle itself for the subsequent injection by actuating the needle. Plunger of the syringe. (Machine-translation by Google Translate, not legally binding)
