The invention discloses a double-riser sealing cover. The double-riser sealing cover mainly comprises a round cover body, an infusion tube, a dosing tube and a film-laminating plate, wherein one end of each of the infusion tube and the dosing tube is connected with the round cover body and the other end of each of the infusion tube and the dosing tube is connected with the film-laminating plate. According to the double-riser sealing cover, water is not permeated completely during sterilization; a dosing hole and an infusion hole are still in an aseptic state after sterilization; the outer surface of a spacer is not required to be disinfected before liquid medicine is injected into or taken out of a container; the problem that crumbs fall off during infusion puncture can be solved; during infusion production, a machine can identify and adjust the direction of the sealing cover conveniently; and a nurse can identify the dosing tube and the infusion tube conveniently when the double-riser sealing cover is used.
