Anti-falling self-sealing joint assembly for medical liquid passage

The invention discloses an anti-falling self-sealing connector assembly for a medical liquid passage. The anti-falling self-sealing connector assembly comprises a liquid outlet connector pipe, a liquid inlet connector pipe and a guide inserting needle. A second sealing plug and a third sealing plug are arranged at a front end opening and a tail end opening of the liquid inlet connector pipe respectively, and a conical sleeve is arranged in the center of the second sealing plug. A first sealing plug is arranged at the open end of the liquid outlet connector pipe. According to the invention, the liquid outlet joint pipe is matched with the butt joint connecting piece to be in butt joint with the liquid inlet joint pipe, and the conical sleeve in the liquid inlet joint pipe penetrates and extends into the inner cavity of the liquid outlet joint pipe to realize communication, so that the liquid outlet joint pipe is automatically separated from the liquid inlet joint pipe when a liquid passage of a patient is sudd
