The utility model relates to the technical field of connecting pipes, and discloses a sterile connecting
pipe which comprises a body, a tightening ring is connected to the outer edge of the body in a clamped mode, an installation hole is formed in the middle of the tightening ring, a clamping spring and a clamping pin are connected to the inner wall of the installation hole in a sleeved mode, a pressure applying ring is fixedly connected to the outer edge of the clamping pin in a sleeved mode, a clamping hole is formed in the outer edge of the body, and the clamping hole is communicated with the clamping spring. The inner wall of the body is fixedly sleeved with a
butt joint pipe, a sealing ring is fixedly assembled on the inner wall of the body, and a
butt joint groove is formed in the end, located on the inner wall of the body, of the
butt joint pipe. By means of the body, the tightening ring and the butt joint pipe structure,
medical staff can directly make the butt joint pipe be in butt joint with the inner wall of the body in the process of butt joint of an infusion tube, and due to the fact that
silica gel materials have the characteristics of
toughness and elasticity, the infusion tube with the large
diameter can also be in butt joint with the body; in this way, the effect that infusion tubes with different diameters can be in butt joint through the connecting tube is achieved, and the infusion efficiency of medical workers on patients is improved.
