[0031] Compared with the related art, the peritoneal dialysis external short tube provided by the utility model has the following beneficial effects:

[0032] The utility model provides an external short tube for peritoneal dialysis. By arranging three pointing blocks on the surface of a connecting tube 1, the connecting tube 1 is rotated so that the three pointing blocks correspond to pointing grooves 4 respectively, thereby expressing the effects of internal connection, half-opening and closing of the connecting tube 1 and the mounting tube 2.

[0033] Second embodiment

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 Based on the peritoneal dialysis external short tube provided in the first embodiment of the present application, the second embodiment of the present application proposes another peritoneal dialysis external short tube. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0035] Specifically, the difference of the peritoneal dialysis external short tube provided in the second embodiment of the present application is that, in the peritoneal dialysis external short tube, a movable groove 6 is opened in the middle of the top of the first pointing block 3, a fixing rod 7 is fixedly installed in the middle of the bottom of the inner cavity of the movable groove 6, a limiting block 9 is fixedly installed on the top of the fixing rod 7, an elastic part 8 is sleeved on the bottom of the outer surface of the fixing rod 7, and a limiting device 5 is sleeved on the outer surface of the limiting block 9.

[0036] The limiting device 5 comprises a marking block 51 , a movable block 52 is fixedly mounted on the bottom of the marking block 51 , a setting hole 53 is opened in the middle of the bottom of the movable block 52 , and a mounting cavity 54 is connected to the top of the setting hole 53 .

[0037] The alignment block 51 is in a triangular block shape, and the movable block 52 is matched with the movable groove 6 .

[0038] The top end of the fixing rod 7 extends to the inside of the setting hole 53 , and the limiting block 9 is arranged inside the installation cavity 54 . The diameter of the limiting block 9 is greater than the diameter of the fixing rod 7 .

[0039] The elastic member 8 is made of spring material, the top end of the elastic member 8 is fixedly connected to the bottom of the movable block 52 , and the bottom end of the elastic member 8 is fixedly connected to the bottom of the inner cavity of the movable groove 6 .

[0040] The three directional blocks have the same structure, and are all provided with a movable groove 6, a fixing rod 7, an elastic member 8, a limit block 9 and a limiting device 5 inside.

[0041] The working principle of a peritoneal dialysis external short tube provided by the utility model is as follows:

[0042] During operation, the user first holds the mounting tube 2 with one hand and rotates the connecting tube 1 with the other hand. The connecting tube 1 drives the pointing block to rotate. When the first pointing block 3 rotates to the bottom of the pointing groove 4, the restoring elastic force of the elastic member 8 pushes the movable block 52 to move upward. The movable block 52 moves upward along the movable groove 6. The movable block 52 drives the marking block 51 to move upward. When the marking block 51 is not restricted by the bottom of the mounting tube 2, the marking block 51 is embedded in the inside of the pointing groove 4 to achieve a restrictive effect.

[0043] When the user rotates the connecting tube 1 again, the marking block 51 of the first pointing block 3 is squeezed by the inclined edge of the pointing groove 4, and as the connecting tube 1 continues to rotate, the first pointing block 3 is squeezed into the interior of the movable groove 6 by the bottom of the mounting tube 2. When the second pointing block 10 and the pointing groove 4 are aligned up and down, the restoring elastic force of the elastic member 8 pushes the movable block 52, so that the marking block 51 is embedded into the interior of the pointing groove 4.

[0044] The same is true for the third pointing block 11 .

[0045] Compared with the related art, the peritoneal dialysis external short tube provided by the utility model has the following beneficial effects:

[0046] The utility model provides an external short tube for peritoneal dialysis, wherein the movable block 52 is pushed upward by the restoring elastic force of the elastic member 8, so that the marking block 51 is embedded in the inside of the pointing groove 4, and when the connecting tube 1 is rotated, the restoring elastic force of the elastic member 8 needs to be overcome, so that there is an obvious pause when the connecting tube 1 is rotated, and at the same time, when the limiting device 5 is embedded in the inside of the pointing groove 4, it is not easy to separate. The device has a simple structure and strong practicality. The connecting tube 1 and the mounting tube 2 are not easy to loosen due to external influences, so that medical accidents caused by accidentally touching the external short tube are avoided, and the safety of the external short tube is improved.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
