Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail, and the explanation of the invention is not limited.
See Fig. 1, Fig. 2, a kind of peritoneal dialysis tube placing operation latch closure, comprise axis 3, axis 3 is provided with the center through hole passed through for peritoneal dialysis pipeline (abdomen is managed thoroughly), the upper and lower two ends of axis are respectively equipped with blade 1 and lower blade 2, and blade 1 and lower blade 2 are equipped with equally distributed perforation;
The axial wall of axis is provided with in the shape of a spiral around the aperture 5 of distribution, and slip is successively through aperture;
Connecting line 5 through center through hole through blade 1 and the corresponding perforation of lower blade 2, in center through hole up and down.
