[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model

[0031] Please refer to Figures 1-7 , the present utility model provides the following technical solutions: a new drainage tube interface device

[0032] Embodiment 1: In order to solve the problem that in the prior art, at the end of drainage, adhesion will form at the interface of the drainage tube, making it difficult to rotate and remove the drainage tube from the indwelling catheter 1, increasing the operation difficulty and time, and then affecting the treatment process of the patient. Therefore, the following solution is disclosed. Specifically refer to Figures 1-3 And Figure 6 And Figure 7 As shown in, it includes an indwelling catheter 1 and a drainage bag connecting tube 2. A first connecting ring 3 is fixedly connected to the bottom of the indwelling catheter 1, and a second connecting ring 4 is fixed to the top of the drainage bag connecting tube 2

[0033] It further includes: buckles 5 are arranged on the outer side of the lower end of the indwelling catheter 1, an annular protrusion 6 is fixedly arranged on the outer side of the upper end of the drainage bag connecting tube 2, card blocks 8 are fixedly connected to the inner wall of the first connecting ring 3 at equal angles, card slots 7 are arranged on the outer side of the second connecting ring 4 at equal angles, the second connecting ring 4 and the first connecting ring 3 are in an insertion connection, the card slots 7 are arranged in an "L" shape, and the card blocks 8 and the card slots 7 are in a clamping connection; abutting blocks 9 are arranged in the second connecting ring 4 at equal angles, and a first spring 10 is installed between the bottom of the abutting block 9 and the inner wall of the second connecting ring 4. The top of the abutting block 9 extends into the inside of the card slot 7, and the abutting block 9 and the second connecting ring 4 are in a sliding connection, and the top end of the abutting block 9 is in contact with the side surface of the bottom of the card block 8

[0034] Insert the second connecting ring 4 on the drainage bag connecting tube 2 into the first connecting ring 3 on the indwelling tube 1. At this time, the clamping block 8 is snapped into the clamping groove 7. Then, rotate the drainage bag connecting tube 2 clockwise, so that the clamping block 8 moves in the clamping groove 7 and presses against the abutting block 9. After that, when the clamping block 8 moves from one side of the abutting block 9 to the other side, the abutting block 9 resets under the elastic force of the first spring 10 and positions the clamping block 8, thus completing the docking of the drainage bag connecting tube 2 and the indwelling tube 1. At the same time, the annular convex part 6 can be grasped and fixed by the buckle 5. Then, when it is necessary to separate the drainage bag connecting tube 2 from the indwelling tube 1, just rotate the drainage bag connecting tube 2 counterclockwise, so that the clamping block 8 slides and resets in the clamping groove 7. Then, pull down the drainage bag connecting tube 2 forcefully, so that the clamping block 8 is separated from the clamping groove 7, and at the same time, the buckle 5 is separated from the annular convex part 6, thus facilitating the separation of the drainage bag connecting tube 2 from the indwelling tube 1, making it easy to replace the drainage bag connecting tube 2, and it is not easy to fall off and leak liquid.

[0035] Embodiment 2: Different from Embodiment 1, in this embodiment, by using the provided sealing ring 11, the sealing performance of the connection position between the first connecting ring 3 and the second connecting ring 4 can be improved to prevent liquid leakage. Specifically, refer to Figure 1 and Figure 6 As shown, below the opposite surfaces of the three buckles 5, there are all convex blocks that fit with the annular convex part 6, and a sealing ring 11 is embedded and installed below the clamping groove 7 on the outer side of the second connecting ring 4;

[0036] When the second connecting ring 4 on the drainage bag connecting tube 2 is inserted into the first connecting ring 3 on the indwelling tube 1, the sealing ring 11 on the outer side of the second connecting ring 4 will closely fit with the inner wall of the first connecting ring 3, thereby improving the sealing performance of the connection position between the first connecting ring 3 and the second connecting ring 4 and preventing liquid leakage.

[0037] Embodiment 3: Different from Embodiment 2, in this embodiment, by inserting the movable block 13 into the corresponding limiting groove, the firmness of the docking between the drainage bag connecting tube 2 and the indwelling tube 1 can be improved. Specifically, refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 7As shown, movable blocks 13 are all slidably connected inside the annular convex part 6, and a third spring 17 is installed between one end of the movable block 13 and the inner wall of the annular convex part 6. A moving plate 15 is connected inside each of the three buckles 5, and a driving block 18 penetrates through one side above the inside of each of the three buckles 5. Sliders are fixed on the sides of the driving block 18 and the moving plate 15, and a second spring 12 is installed between the end of the slider and the inner wall of the buckle 5. Limiting grooves are formed below the opposite surfaces of the three buckles 5, and a guiding block 14 is slidably connected to the inner wall of the limiting groove. The movable block 13 is arranged in a "T" shape, and one end of the movable block 13 penetrates through the inside of the annular convex part 6, and the positions of the three movable blocks 13 correspond to the positions of the three limiting grooves one by one. The guiding block 14 is connected to the moving plate 15 through a connecting plate 16. Both ends of the connecting plate 16 are hingedly connected to the bottom of the moving plate 15 and one end of the guiding block 14 respectively. The moving plate 15 is slidably arranged inside the buckle 5, and the top of the moving plate 15 is inclined. The driving block 18 is slidably connected to the buckle 5, and the end of the driving block 18 is in contact with the inclined surface of the moving plate 15;

[0038] When the buckle 5 moves from above the annular convex part 6 to below, the movable block 13 will be squeezed and retracted into the annular convex part 6. Then, when the position of the movable block 13 corresponds to the limiting groove, the movable block 13 is reset under the elastic force of the third spring 17, so that it is inserted into the corresponding limiting groove, further improving the firmness of the butt joint between the drainage bag connecting pipe 2 and the indwelling catheter 1. Then, when the drainage bag connecting pipe 2 needs to be replaced, by pressing the driving block 18, the driving block 18 squeezes the moving plate 15 and prompts it to move downward. At the same time, the connecting plate 16 rotates and pushes the guiding block 14 to move, so that the guiding block 14 squeezes the movable block 13, and then the movable block 13 is separated from the limiting groove, which can release the limitation of the buckle 5 and the annular convex part 6. Then, when the driving block 18 is released, the driving block 18 and the moving plate 15 are reset under the elastic force of the second spring 12, and at the same time, the connecting plate 16 drives the guiding block 14 to reset.
