Abstract

The utility model relates to the technical field of medical instruments, and discloses a fistulization tube nutrition pump tube connector which comprises a connector body, a nutrition tube connector is installed at the top end of the connector body, a screw fistulization tube connector is arranged at the bottom end of the connector body, and the nutrition tube connector is connected with the screw fistulization tube connector. A fixing plate is arranged on the outer wall of the connector body. According to the utility model, through the arrangement of the straight-mouth fistulization tube joint, the screw-mouth fistulization tube joint and the connecting block, the straight-mouth fistulization tube joint is fixed through the threads of the connecting block, so that the straight-mouth fistulization tube can be connected with the straight-mouth fistulization tube joint, the straight-mouth fistulization tube is further connected with the nutrition tube, and the straight-mouth fistulization tube joint is screwed out from the connecting block; when the screw fistulization tube connector is used, the screw fistulization tube can be directly connected with the screw fistulization tube connector, so that the screw fistulization tube is connected with the nutrition tube, the problem that a common clinical fistulization tube is not matched with the nutrition tube connector is solved, and meanwhile the requirement that the screw fistulization tube and a straight fistulization tube are connected with the nasal feeding nutrition tube is met.
