[0033] like Figures 1 to 5 As shown, an embodiment of this utility model provides a multi-lumen connection tube for abdominal suction, including a suction main tube 1, one end of which is connected to the output end of a suction device; suction branch tubes 2, one end of which is connected to the outer end of a drainage tube placed in a human wound; and a connector 3, one side of which is connected to the other end of the suction main tube 1, and the other side of which is connected to the other end of the suction branch tubes 2. Multiple suction branch tubes 2 are provided. The suction main tube 1 and the suction branch tubes 2 are connected by the connector 3. The connector is made of a rigid material and can provide some support for the suction main tube and the suction branch tubes, thereby facilitating a sealed connection between the suction main tube and the suction branch tubes. By setting the connector, the suction main tube and multiple sets of suction branch tubes can be connected, enabling multi-lumen suction in conjunction with a single suction device. This facilitates tube management and fixation, reduces the risk of tube slippage, reduces the use of suction devices, saves bedside space, facilitates bedside operations for medical staff, and improves work efficiency.

[0034] like Figures 2 to 4As shown, the connector 3 includes a connecting box 4 connected to the main suction tube 1. The connecting box 4 is a box with an open top. A connecting box cover 5 connected to the top opening of the connecting box 4 is connected to the suction branch tube 2. The connecting box cover 5 completely closes the top opening of the connecting box 4. A first connecting sleeve 7 is provided at the bottom of the connecting box 4. The first connecting sleeve 7 is connected to the inside of the connecting box 4. The outer wall of the first connecting sleeve 7 is provided with multiple annular protrusions. One end of the main suction tube 1 is sleeved on the first connecting sleeve 7 and sealed to the connecting box 4. The protrusions on the first connecting sleeve 7 can increase the sealing at the connection with the main suction tube 1. The multiple protrusions can also appropriately increase the friction between the main suction tube 1 and the first connecting sleeve 7, making the connection between the main suction tube 1 and the first connecting sleeve 7 more secure and preventing the main suction tube 1 from easily falling off the first connecting sleeve 7. The connector is formed by the combination of the connecting box and the connecting box cover. The connecting box and the connecting box cover adopt a separable design, which facilitates cleaning of their interiors, making them easy to clean and disinfect. They can be reused multiple times, improving resource utilization.

[0035] The connecting box 4 is a cylindrical structure with flat sides and a smooth, rounded, convex center. An elliptical cavity is formed in the center of the connecting box 4, which connects the main suction tube 1 and multiple suction branch tubes 2. The flat sides of the connecting box 4 increase its contact area with the human body, facilitating fixation and improving stability. Multiple fixing slots 9 are formed on the top wall of the connecting box 4. Multiple second connecting sleeves 10 are provided on the top of the connecting box cover 5. The second connecting sleeves 10 are fixedly connected to the connecting box cover 5 and are internally interconnected. The side wall of the cylinder 10 is provided with a clearance groove 14, which is a fan-shaped through groove inclined relative to the vertical plane. The outer side wall of the second connecting sleeve 10 is provided with a sealing cover 16, which covers the clearance groove 14 and is fixedly connected to the edge of the clearance groove 14. The sealing cover 16 is made of elastic material and has good elasticity, allowing for a certain degree of deformation. A sealing baffle 15 is embedded inside the clearance groove 14. By setting the sealing baffle 15, in conjunction with the clearance groove 14 and the sealing cover 16, the sealing baffle 15 slides into the clearance groove 14 during use, sealing the groove. The side wall of the baffle 15 is in contact with the inner wall of the clearance groove 14, and the sealing baffle 15 is also inclined relative to the vertical plane. The sealing baffle 15 contacts the sealing cover 16, so that the sealing baffle 15 completely closes the second connecting sleeve 10. When the suction branch pipe 2 is not needed, the corresponding second connecting sleeve 10 can be automatically closed by the sealing baffle 15, thereby preventing contamination in the pipeline and liquid leakage. When the suction branch pipe 2 is connected to the second connecting sleeve 10, the suction branch pipe 2 enters the second connecting sleeve 10 and applies a pushing force to the sealing baffle 15, forcing the inclined... The obliquely arranged sealing baffle 15 moves down along the inner wall of the clearance groove 14 and pushes up the sealing cover 16 to deform it. After the sealing baffle 15 is completely withdrawn from the second connecting sleeve 10, the suction branch pipe 2 can continue to enter the second connecting sleeve 10. After the suction branch pipe 2 passes the sealing baffle 15, the sealing baffle 15 exerts a squeezing force on the suction branch pipe 2 under the elastic force of the sealing cover 16, thereby increasing the stability between the suction branch pipe 2 and the second connecting sleeve 10 and reducing the risk of pipe detachment. One end of the suction branch pipe 2 is embedded in the second connecting sleeve 10 and sealed to it.

[0036] like Figure 4 and Figure 6As shown, the inner wall of the second connecting sleeve 10 is provided with a sealing flange 11. The sealing flange 11 is an arc-shaped ring structure. The bottom edge of the sealing flange 11 contacts and is fixedly connected to the second connecting sleeve 10. The diameter of the top edge of the sealing flange 11 is smaller than the inner diameter of the second connecting sleeve 10. When the suction branch pipe 2 is inserted into the second connecting sleeve 10 to a certain depth, the port of the suction branch pipe 2 enters the groove between the sealing flange 11 and the second connecting sleeve 10. When the liquid in the suction branch pipe 2 flows through the second connecting sleeve 10, some of the liquid enters the groove, filling the gap between the suction branch pipe 2 and the inner wall of the second connecting sleeve 10, further increasing the sealing of the connection. The bottom of the connecting box cover 5 is also provided with multiple sets of fixing buckles 13. The positions of the fixing buckles 13 and the fixing slots 9 correspond one-to-one, and the fixing buckles 13 and the fixing slots 9 are compatible.

[0037] like Figure 2 As shown, a filter element 6 is installed inside the connecting box 4. The filter element 6 is a box with an open top, and its volume is smaller than that of the connecting box 4. The opening of the filter element 6 has an edge side wall opening that fits against the inner wall. Several sets of filter holes are opened on the side wall and bottom of the filter element 6. There is a gap between the bottom of the filter element 6 and the bottom of the connecting box 4 to prevent the suction main tube from being blocked when the filter element 6 is filled with filler. By setting the filter element 6, the upper end of the filter element 6 blocks the upper opening of the connecting box 4, forcing the liquid in the suction branch tube 2 to flow through the filter element 6 and be filtered through the filter holes on the filter element 6 before entering the suction main tube 1 from the first connecting sleeve 7. This effectively filters the liquid and prevents tissue fragments carried in the liquid from clogging the pipe. At the same time, it can also collect tissue fragments for easy processing.

[0038] The working principle of this utility model is as follows: First, connect one end of the suction main tube 1 to the output end of the suction device. Then, fit the other end of the suction main tube 1 onto the first connecting sleeve 7. Next, insert one end of each of the multiple suction branch tubes 2 into the second connecting sleeve 10. The other end of the suction branch tubes 2 enters the wound and is fixed to the patient's body with medical tape. When the suction device is activated, a negative pressure vacuum is generated at the connection end of the suction main tube 1, causing suction to be generated in the suction main tube 1, connector 3, and suction branch tubes 2. The accumulated fluid in the wound and the necrotic tissue carried in the accumulated fluid are all drawn into the filter element 6 through the suction branch tubes 2. After being filtered by the filter element 6, the accumulated fluid continues to enter the suction main tube 1 and is discharged into the reservoir. Larger tissue fragments accumulate in the filter element 6 and are cleaned during the suction interval or after the suction is completed.

[0039] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
