[0033] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments and in conjunction with the accompanying drawings.

[0034] As Figures 1-6 shown, an anti-blocking drainage tube includes:

[0035] A three-way joint 1, which is provided with a first interface, a second interface and a third interface;

[0036] A drainage tube head 2, one end of which is provided with a drainage port, and the other end is provided with a connection joint, and the connection joint is adapted to be connected to the first interface of the three-way joint 1;

[0037] Two extension tubes 3, the extension tubes 3 are adapted to communicate with the second interface of the three-way joint 1 or the third interface of the three-way joint 1;

[0038] A switching valve 4, the switching valve 4 is installed on the three-way joint 1, and the switching valve 4 is adapted to be rotated so that the first interface of the three-way joint 1 is selectively connected to the second interface or the third interface;

[0039] Two needleless connectors 5, the needleless connectors 5 are installed on the three-way joint 1, the needleless connectors 5 are provided with a main pipeline communicating with the second interface or the third interface and a branch pipeline communicating with the main pipeline, and a connection port is provided on the branch pipeline;

[0040] The connection port of the needleless connector 5 is adapted to introduce compressed gas.

[0041] In this embodiment, as Figures 1-2 shown, the drainage tube head 2 is used for drainage. When a blockage occurs during the drainage process, the switching valve 4 can be used to switch the drainage direction to another extension tube 3 to ensure the continuity and uninterruptibility of the drainage process. At the same time, the air outlet of the machine capable of providing compressed gas is inserted into the connection port of the needleless connector 5 corresponding to the blocked extension tube 3, and the blocked part is dredged through the air flow pressure, so as to effectively solve the possible blockage problem during the drainage process and ensure the normal operation of the drainage.

[0042] In some embodiments, the number of the needleless connectors 5 and the extension tubes 3 is not limited to two and can be set according to specific requirements. For example, the extension tubes 3 can be installed as needed. When there is only one needleless connector 5, first use the extension tube 3 communicating with the needleless connector 5. After blockage, use the switching valve 4 to switch to the extension tube 3 not communicating with the needleless connector 5. After switching, use compressed gas to dredge the original extension tube 3, and then switch back to the original extension tube 3 after dredging.

[0043] Specifically, as Figures 1-2 shown, a disposable seal is provided on the connection port of the needleless connector 5, and the disposable seal can effectively avoid contamination and maintain the sterile state inside the needleless connector 5. When in use, it is necessary to tear off the disposable seal and insert the air outlet pipe of the machine providing compressed gas into the connection port.

[0044] Specifically, as Figures 1-2 shown, the connection joint of the drainage tube head 2 is a Luer joint.

[0045] In this embodiment, the Luer joint has the advantages of reliable sealing performance and easy disassembly. It can effectively prevent liquid leakage and ensure the safety of drainage.

[0046] Specifically, as Figures 1-2 shown, a conical inclined surface structure is provided at one end of the drainage tube head 2 close to the drainage port.

[0047] In this embodiment, the conical inclined plane structure is conducive to guiding and smoothly inserting into the body, reducing the resistance and discomfort during the insertion process. The inclined plane structure makes the front end of the drainage tube head present a smooth transition, avoiding damage to human tissues by the edge.

[0048] Specifically, as Figures 1-2 shown, the extension tube 3 is a transparent tube.

[0049] In this embodiment, as Figures 1-2 shown, the transparent tube can clearly observe the liquid flow situation inside the tube, such as the flow rate, color, and whether there is blockage, etc., which is convenient for real-time monitoring and diagnosis. In some embodiments, the extension tube 3 can also be a translucent tube.

[0050] Specifically, as Figures 1-2 shown, the anti-blockage drainage tube further includes a flow rate adjustment component, and the flow rate adjustment component is installed on the pipeline of the drainage tube head 2, and the flow rate adjustment component is suitable for adjusting the drainage flow rate of the drainage tube head 2.

[0051] Specifically, as Figures 1-6 shown, the flow rate adjustment component can be the following structure, including:

[0052] Two fixed disks 71, the fixed disks 71 are fixed on the drainage tube head 2, and six arc-shaped grooves are evenly arranged along the circumferential direction on the fixed disks 71;

[0053] Two control disks 72, six linear grooves are evenly arranged along the circumferential direction on the control disks 72;

[0054] Six adjusting blades 73, each adjusting blade 73 is hinged with a cylindrical pin, and the cylindrical pins sequentially pass through the linear grooves and the arc-shaped grooves;

[0055] The ends of the six adjusting blades 73 are suitable for continuously splicing around the center of the fixed disk 71 to form a flow limiting hole;

[0056] The control disk 72 is suitable for being rotated, and drives the six adjusting blades 73 to slide along the arc-shaped grooves and the linear grooves through the cylindrical pins to adjust the size of the flow limiting hole.

[0057] In this embodiment, as Figures 1-6 shown, the flow rate adjustment component is installed on the pipeline of the drainage tube head 2, and the purpose is to adjust the flow rate of the drained liquid as needed. It can accurately control the drainage flow rate, and it is convenient to adjust the appropriate drainage rate according to different conditions and treatment requirements. Through the adjustment of the flow limiting hole, interference to the entire pipeline system is avoided.

[0058] The fixed disk 71 is fixed on the pipeline, and the control disk 72 can rotate. The cylindrical pins of the six adjusting vanes 73 are simultaneously inserted into the arc-shaped grooves of the fixed disk 71 and the straight grooves of the control disk 72. When the control disk 72 rotates, the vanes 73 will slide under the action of the two groups of grooves, thereby changing the size of the flow-limiting aperture formed at their ends. The smaller the flow-limiting aperture, the greater the resistance to fluid passage, and the smaller the flow rate, and vice versa.

[0059] During use, the size of the flow-limiting orifice can be adjusted by rotating the rotation control part on the control disk 72, and the flow rate change on the drainage pipeline can be observed until the ideal flow rate is achieved. When it is necessary to accelerate or slow down the drainage, just adjust it again.

[0060] In some embodiments, the number of the fixed disk 71 and the control disk 72 is not limited to two and can be set according to specific requirements. The number of the adjusting vanes 73 used is also not limited to six.

[0061] Specifically, as Figure 4 shown, a rotation control part is also provided on the outer circumferential surface of the control disk 72.

[0062] In this embodiment, as Figure 4 shown, the rotation control part facilitates manually operating the rotation of the control disk 72, thereby adjusting the aperture size of the flow-limiting orifice of the flow rate adjustment assembly.

[0063] The above specific embodiments further elaborate on the technical problems solved, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit 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.
