Sterilized plastic device for dilution and pressurization of self-breaking syringe

The utility model relates to a sterilizing plastic dilution and pressurizing device used for matching a self destroying injector which can prevent the injection usage. The sterilizing plastic dilution and pressurizing device is formed by the mutual connecting and fixing of a plastic neilsbed (12) molded by integral injection and a plastic elastic flat liquid/air storage cell (8), wherein, the plastic neilsbed (12) is provided with a plastic pinhead (3) and a neilsbed hollow joint (11). A rubber cap (15) close to the body of the needle is sheathed outside the needle pin; an aseptic diluent is perfused into the liquid storage cell with a fixed ration from a hopper perfusion opening (3) after being sterilized by ethylene oxide. The air storage cell omits the perfusion working procedure; then the location of a seal line is sealed by heat pressing; the outside thereof is packaged into a finished product by plastic bag tension seal technology. The sterilizing plastic dilution and pressurizing device belongs to the
