[0002] A clamping and fixing structure for catheters is an innovative structural design for securing catheters. It utilizes a unique clamping method to securely secure the catheter, preventing it from shifting or falling out. This structure is easy to operate, quick to install and remove, and improves the safety and stability of catheter use. It is suitable for catheter fixation needs in a variety of fields, including medical and industrial settings.

[0003] In announcement number CN220110248U, the utility model discloses a tube placement fixing structure, which belongs to the technical field of medical devices, including a mounting block, a first splint is provided on the front of the mounting block, a second splint is hinged on the front of the first splint, anti-slip pads are provided in the first and second splints, a limiting component is provided on the back of the second splint, a placement groove is provided on the front of the first splint, the limiting component is overlapped with the placement groove, and a limiting hole is provided on the side of the first splint. The catheter fixing structure, by providing a first splint, a second splint, a fixing frame, a limiting rod, a connecting plate and a limiting hole, further avoids the cumbersome fixing operation of the existing catheter fixing structure by using tape, which not only ensures that it can be conveniently reused during use, but also makes the operation process of fixing the catheter more convenient and quick. However, the above-mentioned device structure is relatively simple. When in use, the flow rate of the liquid medicine in the catheter cannot be adjusted as needed, and the device cannot be quickly disassembled during use. For this reason, we propose a clamping fixing structure for the catheter. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a clamping and fixing structure for placing a tube, comprising a fixing seat 1:

[0023] The fixing seat 1 is provided with restraint belts 2 on both the front and rear sides, three sets of clamping seats 4 are provided on the upper and lower ends of the right side of the fixing seat 1, mounting rods 5 are provided on both the front and rear ends of the right side of the fixing seat 1, a cross bar 6 is provided between the right ends of the two sets of mounting rods 5, an adjusting rod 10 is inserted in the middle of the cross bar 6, and a clamping strip 11 is installed on the left end of the adjusting rod 10.

[0024] Velcro 3 is provided at the ends of the two sets of restraints 2 that are away from each other. The Velcro 3 can be used to quickly complete the connection and separation of the restraints 2, making the installation and disassembly process of the entire fixed structure faster and more convenient. Since the position of the Velcro 3 can be adjusted as needed, it can adapt to the different sizes of patients' limbs and provide a more personalized fixation solution.

[0025] Soft pads 12 are provided inside the multiple groups of clamping seats 4 and inside the left side of the clamping strip 11. The soft pads 12 can provide additional cushioning and protection for the tubes to avoid damage or wear to the tubes during the clamping process or use. This is crucial to ensuring the integrity of the tubes and extending their service life. The elastic characteristics of the soft pads 12 can increase the contact area between the clamping seat 4 and the tubes, thereby improving the stability of the entire fixed structure, which helps to reduce shaking or movement of the tubes during use and ensure the safety and reliability of the tubes.

[0026] Both ends of the cross bar 6 are provided with slots, and positioning springs 7 are provided in the slots. The ends away from the two sets of positioning springs 7 are provided with insertion rods 8, and the sides close to the right ends of the two sets of mounting rods 5 are provided with matching slots. By combining the positioning springs 7 and the insertion rods 8, and then inserting the insertion rods 8 into the slots, the positioning springs 7 support the insertion rods 8, which can effectively prevent the cross bar 6 from sliding or loosening during use, thereby improving the stability of the entire fixed structure. This is especially important for medical tubes that need to remain fixed for a long time, such as catheters, endotracheal tubes, etc.

[0027] The two groups of insertion rods 8 are both provided with a connecting block on the right side of the end close to each other, and two groups of matching sliding grooves are opened on the right side of the cross bar 6, and the right ends of the two groups of connecting blocks are connected with adjusting pieces 9. The two groups of adjusting pieces 9 are relatively arranged in an L-shaped structure. The L-shaped structure of the adjusting piece 9 makes it easier for the operator to adjust. The connecting block passes through the sliding groove opened in the cross bar 6, driving the insertion rod 8 to move, thereby moving the insertion rod 8 and disengaging the insertion rod 8 from the slot opened in the mounting rod 5, making it convenient for the operator to disassemble and assemble the cross bar 6.

[0028] The outer side of the adjusting rod 10 is set to a threaded structure, and a threaded hole matching it is opened in the middle position of the cross bar 6, and the left end of the adjusting rod 10 is rotatably installed on the right side of the clamping bar 11. The adjusting rod 10 with a threaded structure allows the operator to accurately adjust the position of the clamping bar 11 by rotation, thereby facilitating the clamping bar 11 to clamp the tube and ensure the stability of the tube.

[0029] Three groups of positioning sleeves 13 are evenly arranged on the upper side of the clamping strip 11, and the right end of the positioning sleeve 13 is provided with an adjusting bolt 14 through a threaded structure. The adjusting bolt 14 on the outside of the positioning sleeve 13 can be used to adjust the flow rate of the liquid medicine in the tube during use, thereby adjusting it according to needs.

[0030] Working principle: Tie the device to the appropriate position with the restraint belt 2, and then fix it with the Velcro 3, set the tube in the two sets of upper and lower opposite card seats 4, and then install the cross bar 6 between the mounting rods 5, and use the positioning spring 7 to drive the insertion rod 8 to fix the cross bar 6, and then rotate the adjusting rod 10 to drive the clamping bar 11 to clamp the tube, and then rotate the adjusting bolt 14 to adjust the flow rate of the liquid medicine in the tube.
