[0002] CVC tube refers to a central venous catheter, which is a type of intravascular tube placed in a large vein to measure central venous pressure, which is used to evaluate circulatory physiological central venous catheter parameters and estimate the amount of body fluid. Because of the purpose of measuring central venous pressure, large amounts of rapid intravenous infusions often occur in surgeries where blood loss may be large, or to maintain blood pressure during emergency treatment. It is also used to establish a good infusion channel for patients who require repeated infusions, avoid the pain of repeated punctures, and prevent the CVC tube from causing harm to the patient due to movement of the tube during infusion. A fixation device is usually provided on the outside of the CVC tube.

[0003] When installing and using existing CVC tubes, firstly, the fixing structure of some CVC tubes is single and unstable in use, which limits the use of the CVC tubes and is not conducive to people's use.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0033] See also Figures 1 to 6 In an embodiment of the utility model, a novel tunnel-type CVC external fixation device comprises a CVC tube body and a base plate 1 movably arranged on the CVC tube body, a tube-penetrating tunnel 2 is provided through the base plate 1, and a receiving cavity 3 is provided inside the base plate 1, and the receiving cavity 3 and the tube-penetrating tunnel 2 are communicated with each other;

[0034] A clamping assembly is provided in the tube-threading tunnel 2 and the accommodating cavity 3, and an adjusting assembly is provided on the top surface of the base plate 1. The adjusting assembly is connected to the clamping assembly, and the clamping assembly can quickly clamp or release the CVC tube body under the action of the adjusting assembly, so that the base plate 1 and the CVC tube body can be switched between a fixed state or a mutually slidable state.

[0035] In the present solution, by cooperating with each other, the clamping assembly and the adjusting assembly can not only quickly switch the fixed and non-fixed states of the CVC tube body, but also make it easier for people to change the position of the base plate 1, thereby adapting to people's needs for the position of the base plate 1, and by utilizing the self-locking function of the adjusting assembly, the CVC tube body and the base plate 1 can be fixed more firmly, thereby ensuring stability during use.

[0036] As a further solution of the utility model, the clamping assembly includes a moving rod 4 slidably arranged inside the accommodating cavity 3, one end of the moving rod 4 extends into the pipe-through tunnel 2 and the other end extends to the outside of the base plate 1;

[0037] An arc-shaped pressing plate 5 is fixedly disposed at one end of the moving rod 4 , and a roller 6 is fixedly disposed at the other end of the moving rod 4 .

[0038] In this embodiment, when the moving rod 4 moves toward the pipe-through tunnel 2, the arc-shaped pressing plate 5 moves along with the moving rod 4, thereby squeezing and fixing the branch pipe 18 inside the pipe-through tunnel 2, so that the base plate 1 and the branch pipe 18 are fixedly connected;

[0039] When the moving rod 4 moves away from the pipe-through tunnel 2, the arc-shaped pressing plate 5 will be separated from the branch pipe 18, so that the base plate 1 can slide on the outer wall of the branch pipe 18, thereby changing the position of the base plate 1 on the branch pipe 18 as needed.

[0040] As a further solution of the utility model, a baffle 7 is fixedly provided on the outer wall of the moving rod 4, and a spring 8 is movably sleeved on the outer wall of the moving rod 4, and two ends of the spring 8 are respectively against the inner wall of the accommodating cavity 3 and a side wall of the baffle 7.

[0041] In this embodiment, due to the presence of the spring 8, the roller 6 always abuts against the worm gear 11 in the absence of external force. When the moving rod 4 moves toward the pipe tunnel 2, the baffle 7 will be driven to further squeeze the spring 8; when the moving rod 4 moves away from the pipe tunnel 2, the spring 8 will drive the moving rod 4 to reset through the baffle 7.

[0042] As a further solution of the utility model, the adjustment assembly includes a cover plate 9 fixedly arranged on the top of the base plate 1, and a rotating shaft 10 is rotatably arranged on the inner side wall of the cover plate 9;

[0043] A worm wheel 11 is fixedly provided on the outer wall of the rotating shaft 10 , and one side wall of the worm wheel 11 abuts against the roller 6 . An oblique block 12 is also provided on one side wall of the worm wheel 11 , and the oblique block 12 corresponds to the position of the roller 6 .

[0044] In this embodiment, since the positions of the oblique block 12 and the roller 6 correspond, when the worm wheel 11 rotates, the oblique block 12 will follow the rotation of the worm wheel 11 and contact the roller 6. Under the action of the oblique block 12, the roller 6 will drive the moving rod 4 to move into the pipe tunnel 2, so that the arc-shaped pressure plate 5 clamps and fixes the branch pipe 18 in the pipe tunnel 2.

[0045] The cover plate 9 is used for rotatably supporting the rotating shaft 10 , and the rotating shaft 10 is used for rotating the worm gear 11 disposed inside the cover plate 9 .

[0046] As a further solution of the utility model, a worm 13 is rotatably provided on the cover plate 9, the worm 13 is meshed with the worm wheel 11, and a knob 14 is fixedly provided at one end of the worm 13;

[0047] The outer wall of the base plate 1 is fixedly provided with a Velcro 15, and the Velcro 15 is used to fix the base plate 1 on the patient's neck.

[0048] In this embodiment, since the worm 13 and the worm wheel 11 are meshed with each other, when the knob 14 is rotated by an external force, the knob 14 will drive the worm 13 to rotate, and the worm wheel 11 will rotate with the rotation of the worm 13;

[0049] Because the worm 13 and the worm wheel 11 have a self-locking function, the stability of the base plate 1 and the branch pipe 18 when they are fixed can be ensured;

[0050] The base plate 1 is fixed to the patient's neck by means of the Velcro 15 fixed to the outer wall of the base plate 1, thereby preventing the CVC tube body from moving.

[0051] As a further solution of the utility model, the CVC tube body includes a diverter 16, one end of the diverter 16 is connected to a retention tube 17, the other end of the diverter 16 is connected to a branch pipe 18, one end of the branch pipe 18 passes through the tube tunnel 2, so that the base plate 1 is sheathed on the outside of the branch pipe 18.

[0052] In this embodiment, one end of the indwelling tube 17 is placed in the vein, and the liquid medicine will enter the shunt 16 through the branch tube 18, and then be input into the human body's vein through the indwelling tube 17 connected to one end of the shunt 16;

[0053] Since one end of the branch pipe 18 passes through the pipe tunnel 2, the base plate 1 will be sleeved on the outer wall of the branch pipe 18 through the pipe tunnel 2, and then the clamping component and the adjustment component are used to switch the base plate 1 and the branch pipe 18 between the fixed or non-fixed state.

[0054] As a further solution of the utility model, a connector 19 is fixedly provided at one end of the branch pipe 18 , and a cap 20 is sleeved on the outer wall of the connector 19 .
