Abstract
The invention discloses a hard double connector, comprising a base provided with a mixing channel and a transfusion channel. The mixing channel is extended out of the base to form a mixing connector. A circular bump is protruded along the periphery of the mixing connector on the outer wall. The circular bump is provided with an external thread. A clasp is arranged on the outer wall of an end opening of the mixing connector which is provided with a membrane for sealing the mixing channel. The outer diameter of the clasp is not greater than that of the circular bump. When used, the base is welded on a transfusion soft bag, the mixing connected is inserted into the bottom of a syringe body and the clasp on the mixing connector is located on a positioning ring of the syringe body so that the syringe body is fixed on the mixing connector. During mixing, the syringe body is rotated downward so that the bottom of a dosing needle pierces through the membrane and a medicine container in a mixing nozzle is communicated with the transfusion soft bag. When the hard double connector is used, the hard double connector is unnecessary to connect by tubes and to use a handle easy to bend, thereby not only reducing the installation stations of the tubes, but also avoiding the leakage at the welding seam caused by tube welding deficiencies. Meanwhile, the hard double connector is integrally molded and has a wider scope of application.
