Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it.

[0030] Please refer to Figures 1 to 3 , a drainage three-way pipe 100 provided in the embodiment of the present utility model includes a three-way pipe body 120 and a universal interface 110. The universal interface 110 is installed at the first end of the three-way pipe body 120; generally, the three-way pipe body 120 has three connection ports, and the universal interface 110 is installed on one of the ports. In this embodiment, the universal interface 110 is used to connect an external indwelling pipe;
[0031] Specifically, the universal interface 110 includes a pipe body, an adjusting member 111, a sleeve 115, and a clamping member 114. The adjusting member 111 is movably arranged on the pipe body and can move along the axial direction of the pipe body. The sleeve 115 is arranged at the end of the pipe body and is coaxially arranged with the pipe body. The clamping members 114 are distributed along the circumference of the pipe body, and a clamping area is formed between the clamping members 114 and the sleeve 115. When the adjusting member 111 moves towards the sleeve 115, it drives the clamping members 114 to converge towards the axial direction of the sleeve 115.
[0032] During use, the indwelling pipe is sleeved outside the sleeve 115, and at least a part of the indwelling pipe is located within the clamping area. By moving the adjusting member 111, it moves along the pipe body. During the process of the adjusting member 111 moving towards the sleeve 115, the adjusting member 111 can make the clamping members 114 converge by extrusion and fix the indwelling pipe on the sleeve 115, so that the indwelling pipes with pipe diameters within the clamping area interval can all be connected to the sleeve 115, thereby enabling the drainage three-way pipe 100 to connect indwelling pipes with different pipe diameters, and further increasing the adaptability of the drainage three-way pipe 100 in connecting indwelling pipes.
[0033] It should be noted that there is a gap between adjacent clamping members 114 to enable the clamping members 114 to have sufficient expansion space when converging.
[0034] Optionally, the pipe body has a threaded section 112 and a straight tube section 113. The adjusting member 111 is in threaded fit with the threaded section 112, and the clamping members 114 are distributed along the circumference of the straight tube section 113.
[0035] Furthermore, the radius of the straight tube section 113 is greater than the radius of the sleeve 115. The straight tube section 113 transitions to the sleeve 115 through a flat plane, and one end of the clamping member 114 is fixed on the flat plane. The clamping member 114 has a bent portion to enable the clamping member 114 to extend away from the axis of the sleeve 115. The radius after the clamping member 114 extends gradually increases and is greater than the inner diameter of the adjusting member 111.
[0036] Specifically, the bent portion makes the clamping member 114 extend away from the sleeve 115, so that the clamping member 114 forms a structure with a gradually changing opening, and the gradually changing opening gradually becomes smaller towards the side of the pipe body, and thus it can be applicable to indwelling pipes with different pipe diameters;
[0037] In addition, the clamping member 114 is installed on the flat plane of the straight tube section 113, enabling the adjusting member 111 to contact the clamping member 114 when moving, so that the clamping member 114 converges inwards.
[0038] Refer to Figure 2 and Figure 3, the adjusting member 111 is threadedly engaged with the threaded section 112 of the pipe body, so that when the adjusting member 111 is rotated, the adjusting member 111 can move along the direction of the pipe body. When it moves a certain distance, the adjusting member 111 can contact the clamping member 114 to form an extrusion effect, thereby driving the clamping member 114 to converge towards the sleeve 115 to form a clamping effect on the indwelling pipe. Further, the clamping members 114 are circumferentially distributed on the straight tube section 113, so that the clamping members 114 uniformly fix the indwelling pipe when clamping the indwelling pipe, improving the connection effect.
[0039] Furthermore, a convex portion is provided on one side of the clamping member 114 close to the axis direction of the sleeve 115. Through the arrangement of the convex portion, the clamping member 114 can further clamp the indwelling pipe during the converging process, so as to improve the clamping effect of the universal interface 110 on the indwelling pipe.
[0040] It should be noted that the drainage three-way pipe 100 further includes a conventional pipe interface 140, and the conventional pipe interface 140 is arranged at the second end of the three-way pipe body 120. The conventional pipe interface 140 is used to connect the drainage pipe. By connecting with the drainage pipe through the conventional pipe interface 140, the drainage three-way pipe 100, the drainage pipe and the indwelling pipe form a passage, so that the effusion in the patient's body can be introduced into the drainage bag.
[0041] It should be further noted that the drainage three-way pipe 100 further includes a first Luer interface 130, and the first Luer interface 130 is arranged at the third end of the three-way pipe body 120. By arranging the first Luer interface 130 at the third end of the three-way pipe body 120, the first Luer interface 130 can be connected to a conventional indwelling pipe, so as to realize simultaneous drainage. In addition, when the first Luer interface 130 is not connected to the indwelling pipe, it is in a closed state.
[0042] In the second aspect, as Figure 4 shown, an embodiment of the present invention provides a drainage device, which includes the drainage three-way pipe 100 of the first aspect, and further includes a drainage pipe 200 and a drainage bag 400. One end of the drainage pipe 200 is connected to the conventional pipe interface 140 of the drainage three-way pipe, and the other end of the drainage pipe 200 is connected to the interface of the drainage bag 400 through a second Luer interface 300.
[0043] Connect the indwelling pipe through the universal interface 110 or the first Luer interface 130 of the drainage three-way pipe 100, connect the drainage pipe 200 to the conventional pipe interface 140, and connect the other end of the drainage pipe 200 to the drainage bag 400 through the second Luer interface 300 to form a drainage passage, so that the effusion in the patient's body can be introduced into the drainage bag 400.
[0044] It should be noted that in this embodiment, the drainage tube 200 is spiral. Through the spiral arrangement of the drainage tube 200, it has a certain telescopic space, avoiding the easy pulling caused when the patient turns over or suddenly gets up, resulting in the drainage tube 200 being extremely easy to separate from the drainage bag 400 due to pulling.
[0045] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
