[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1 and Figure 2As shown, a double-head infusion tube comprises: a first infusion tube 1 and a second infusion tube 2, wherein the first infusion tube 1 and the second infusion tube 2 are separated at the upper part and connected as a whole at the lower part.

[0025] A tube clamp is arranged on the upper part of the first infusion tube 1 and the second infusion tube 2, and the tube clamp includes a tube clamp body 3, the interior of the tube clamp body 3 is hollow to form a sliding groove, a through groove 4 is arranged on one side of the sliding groove, and the through groove 4 passes through the tube clamp body 3 and extends from the sliding groove to the outside of the tube clamp body 3.

[0026] like Figure 2 and Figure 5 As shown, a first flow-limiting protrusion 5 is provided at both ends of the sliding groove in the tube clamp body 3, and a liquid infusion tube passage 6 is provided on one side of the first flow-limiting protrusion 5, and the liquid infusion tube passage 6 extends from the top surface to the bottom surface of the tube clamp body 3. The first liquid infusion tube 1 and the second liquid infusion tube 2 are respectively located in the two liquid infusion tube passages 6. Preferably, the first flow-limiting protrusion 5 is a semicircular structure, and its top can abut against one side of the liquid infusion tube.

[0027] like Figure 3 As shown, a sliding block 7 is slidably arranged in the sliding groove, and a second flow-limiting protrusion 8 is arranged at both ends of the sliding block 7. Preferably, the second flow-limiting protrusion 8 is a semicircular structure. The second flow-limiting protrusion 8 interacts with the first flow-limiting protrusion 5 to realize the on-off of the infusion tube. The first flow-limiting protrusion 5 and the second flow-limiting protrusion 8 are respectively located on both sides of the infusion tube. Moving the sliding block 7 can change the distance between the first flow-limiting protrusion 5 and the second flow-limiting protrusion 8. When the two are close to each other, the infusion tube is disconnected, and when the two are far away, the infusion tube is open.

[0028] A toggle block 9 is provided on one side of the sliding block 7, and the toggle block 9 extends from the through slot 4 to the outside of the tube clamp body 3, so that the medical staff can toggle and more easily move the sliding block 7. A friction protrusion 14 is provided on the top surface of the toggle block 9 to increase friction and prevent slipping.

[0029] like Figure 2 and Figure 4 As shown, the top and bottom surfaces of the sliding block 7 are both provided with a T-shaped clamping seat 10. The bottom of the T-shaped clamping seat 10 is fixedly connected to the sliding block 7, and first buckles 11 are provided at both ends. The thickness of the T-shaped clamping seat 10 gradually increases from both ends to the center. The first buckle 11 is a triangular structure.

[0030] A pressing block 12 is provided on the top surface of the T-shaped clamp 10 near the first buckle 11, and the pressing block 12 extends from the openings on the top and bottom surfaces of the tube clamp body 3 to the outside of the tube clamp body 3. The pressing block 12 can press down the cross arm of the T-shaped clamp 10, so that the first buckle 11 moves toward the side of the sliding block 7, so as to break the fit between the buckles.

[0031] A second buckle 13 is provided inside the pipe clip body 3. The second buckle 13 is arranged corresponding to the first buckle 11 and can be mutually clamped. When the first buckle 11 and the second buckle 13 are mutually clamped, the first current-limiting protrusion 5 and the second current-limiting protrusion 8 are mutually close to each other, so that the squeezed infusion tube is disconnected.

[0032] Preferably, a rounded corner is provided at the top end of the pressing block 12 to reduce sharpness.

[0033] During use, the operator moves the sliding block 7 to move to one side in the sliding groove, so that the first current-limiting protrusion 5 and the second current-limiting protrusion 8 are abutted. At this time, the first buckle 11 and the second buckle 13 are clamped, the position of the sliding block 7 is fixed, and one infusion tube passage is realized while the other infusion tube is disconnected. When it is necessary to switch the on-off state, the operator presses the upper and lower pressing blocks 12 by hand, so that the cross arm of the T-shaped card seat 10 is pressed down to release the cooperation between the first buckle 11 and the second buckle 13, and then the sliding block 7 is moved to move to the other side until the first current-limiting protrusion 5 and the second current-limiting protrusion 8 at the other end are in cooperation.

[0034] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
