The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model embodiment provides a convenient disassembly and assembly type catheter fixing clip, such as... Figure 1-5 As shown, it includes a receiving belt 1; fixing belts 2 located at both ends of the receiving belt 1; and a fixing body located on the receiving belt 1. The fixing body includes: a first fixing seat 3 located on the receiving belt 1; a second fixing seat 4 hinged to the side of the first fixing seat 3; a lower groove and an upper groove with a semi-circular cross-section respectively opened on the opposite side of the first fixing seat 3 and the second fixing seat 4, the lower groove and the upper groove fitting together to form a cylindrical cavity for fixing the conduit; a plurality of return springs 5 ​​are provided at the top of the inner cavity of the upper groove, and a damping strip is integrated inside the return spring 5; a rubber fastening ring 6 is provided on the other side of the plurality of return springs 5, the fastening ring 6 is arc-shaped; a set of guide blocks 7 are symmetrically arranged on both outer walls of the fastening ring 6, and the two guide blocks 7 slide with the upper groove.

[0026] It should be noted that traditional catheter fixation methods are difficult to adapt to catheters of different diameters, resulting in poor fixation effects and the risk of catheter dislodgement or displacement, affecting treatment outcomes and posing safety hazards. Furthermore, the installation and removal processes are cumbersome, requiring additional tools or equipment, causing inconvenience to medical staff. This solution, through the design of a reset spring 5 and an arc-shaped rubber fastening ring 6 within the upper groove, can automatically adapt to catheters of various diameters and provide additional fixing force, ensuring that the catheter will neither slip nor shift during fixation, significantly improving the stability and adaptability of the fixation. Simultaneously, installation is achieved using a fixing strap 2 with male and female hook and loop fasteners 15 and 16. These hook and loop fasteners have strong adhesive force; users simply need to wrap the fixing strap 2 around the object to be fixed and attach the hook and loop fasteners to quickly and firmly fix the catheter clamp in the desired position. This installation method is not only simple and quick, but the reusability of the hook and loop fasteners also allows users to easily remove and re-fix the catheter clamp when needed, providing greater flexibility and convenience.

[0027] Specifically, in this embodiment, the solution mainly includes a receiving belt 1; fixing belts 2 located at both ends of the receiving belt 1; and a fixing body located on the receiving belt 1. The fixing body mainly consists of a first fixing seat 3 and a second fixing seat 4 located on the receiving belt 1. These two fixing seats are connected by a hinge, allowing them to rotate relative to each other. On the opposite sides of the first fixing seat 3 and the second fixing seat 4, a semi-circular lower groove and an upper groove are designed respectively. When it is necessary to fix the conduit, the user first places the conduit in the lower groove, and then closes the second fixing seat 4, so that the upper groove and the lower groove fit tightly together. In this way, the two grooves are combined to form a complete cylindrical chamber, which firmly fixes the conduit in it.

[0028] To improve the stability and adaptability of the fixation, multiple return springs 5 ​​are installed at the top of the inner cavity of the upper groove. In addition, the other end of the return spring 5 is connected to an arc-shaped rubber fastening ring 6. This fastening ring 6 slides with the upper groove through the guide blocks 7 on both sides, and can move stably within a certain range. When the catheter is placed into the cylindrical cavity, under the action of the return spring 5, the fastening ring 6 will automatically move towards the catheter and fit tightly against the outer wall of the catheter, providing additional fixing force for the catheter.

[0029] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the fixing body also includes: fastening pads 8 disposed at the ends of both sides of the lower groove; the upper surfaces of the two fastening pads 8 are provided with several anti-slip protrusions 9.

[0030] In this embodiment, when the catheter is placed in the lower groove and the upper groove and lower groove are tightly fitted together to form a complete cylindrical cavity as the second fixing seat 4 is closed, the fastening pad 8 is in direct contact with the catheter, and through the several anti-slip protrusions 9 provided on its upper surface, it effectively prevents the catheter from sliding or shifting during the fixing process.

[0031] These anti-slip protrusions 9 not only increase the friction between the fastening pad 8 and the catheter, but also provide additional support points for the catheter through their tiny protruding structure, thereby further improving the firmness and stability of the fixation.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a fixing rod 10 is provided on the side of the second fixing seat 4 away from its hinge end. A connecting spring 11 is provided on the outer wall of the fixing rod 10. A damping strip is provided inside the connecting spring 11. A fixing buckle 12 is provided on the side of the connecting spring 11 away from the fixing rod 10.

[0033] In this embodiment, the fixing rod 10 serves as a support and connection, and the connecting spring 11 has a built-in damping strip, which gives the connecting spring 11 a certain damping effect during the extension and contraction process, thereby increasing the stability and buffering performance of the fixation. When the second fixing seat 4 is closed, forming a complete cylindrical cavity with the first fixing seat 3 to fix the conduit, under the action of the elastic force of the connecting spring 11, the fixing buckle 12 is tightly engaged with the first through hole 13 on the first fixing seat 3. In this way, the second fixing seat 4 is firmly locked in the closed position, and the conduit is also steadily fixed in the cylindrical cavity.

[0034] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, the first fixing seat 3 has a first through hole 13 on the side opposite to the fixing rod 10, and the outer wall of the first fixing seat 3 has a second through hole 14 that communicates with the first through hole 13.

[0035] In this embodiment, as the retaining buckle 12 moves, it gradually approaches and eventually enters the first through hole 13 on the first fixing seat 3 to form a tight engagement; during this process, the elastic force of the connecting spring 11 ensures that the retaining buckle 12 can be firmly locked in the second through hole 14, thereby realizing a stable connection and locking between the second fixing seat 4 and the first fixing seat 3.

[0036] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, a male hook and loop fastener 15 is provided on the upper surface of the end of one of the fixing straps 2; a female hook and loop fastener 16 that is tightly engaged with the male hook and loop fastener 15 is provided on the lower surface of the end of the other fixing strap 2.

[0037] In this embodiment, when it is necessary to fix the catheter in a certain position, the catheter is first placed into the cylindrical cavity formed by the first fixing seat 3 and the second fixing seat 4, and the second fixing seat 4 is closed to ensure that the catheter is firmly fixed; then, the user wraps the end of the fixing strap 2 with male hook and loop fastener 15 around the object to be fixed, such as the patient's limb, hospital bed, operating table, etc., and tightly attaches the male hook and loop fastener 15 to the female hook and loop fastener 16 provided on the other fixing strap 2;

[0038] Because of the strong adhesive force between the male hook and loop fastener 15 and the female hook and loop fastener 16, they can quickly and firmly bond together, thus securing the catheter clamp in the desired position. This design not only simplifies the fixing process but also improves the reliability and convenience of fixing. The reusability of the hook and loop fasteners also means that users can easily remove and re-fix the catheter clamp when needed without damaging the fixing band 2 or the hook and loop fasteners. This provides users with greater flexibility and convenience, enabling the catheter clamp to adapt to different usage scenarios and needs.

[0039] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, several first heat dissipation holes 17 are provided through the edges of both sides of the two fixing straps 2, and the several first heat dissipation holes 17 are distributed along their length direction.

[0040] In this embodiment, the design of the first heat dissipation hole 17 also enhances the breathability of the fixing strap 2, allowing users to experience a more comfortable use when using the tube fixing clip for a long time.

[0041] In a further preferred embodiment of this utility model, such as Figure 4-5 As shown, a second heat dissipation hole 18 is provided through both sides of the receiving belt 1.

[0042] In this embodiment, the second heat dissipation holes 18 opened on both sides of the upper edge of the receiving strap 1 effectively improve the heat dissipation performance of the guide clamp and the user comfort by providing unobstructed heat release channels and enhancing breathability.

[0043] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the fixing strap 2 is made of elastic material.

[0044] In this embodiment, the elastic material also gives the fixation strap 2 good adaptability and comfort. No matter how the user's body shape or fixation position changes, the elastic fixation strap 2 can be flexibly adjusted to ensure that the catheter fixation clip is always kept in the correct position, while reducing discomfort to the user.

[0045] Working Principle: The main structure of this device consists of a first fixing seat 3 and a second fixing seat 4 mounted on the receiving belt 1. These two fixing seats are connected by a hinge, allowing them to rotate relative to each other. On the opposite sides of the first fixing seat 3 and the second fixing seat 4, there are semi-circular lower and upper grooves, respectively. When it is necessary to fix the conduit, the user first places the conduit in the lower groove. Then, the second fixing seat 4 is closed, so that the upper groove and the lower groove fit tightly together, forming a complete cylindrical chamber, which firmly fixes the conduit in it. In order to improve the stability and adaptability of the fixation, multiple return springs 5 ​​are set at the top of the inner cavity of the upper groove. The other end of the return spring 5 is connected to an arc-shaped rubber fastening ring 6. This fastening ring 6 slides with the upper groove through the guide blocks 7 on both sides, and can move stably within a certain range. When the conduit is placed into the cylindrical chamber, under the action of the return spring 5, the fastening ring 6 will automatically move towards the conduit and fit tightly against the outer wall of the conduit, providing additional fixing force for the conduit. It is suitable for fixing conduits of different diameters.

[0046] During the process of placing the conduit into the lower groove and closing the second fixing seat 4, the fastening pad 8 comes into direct contact with the conduit; the several anti-slip protrusions 9 on the upper surface of the fastening pad 8 effectively prevent the conduit from sliding or shifting during the fixing process; these anti-slip protrusions 9 not only increase the friction between the fastening pad 8 and the conduit, but also provide additional support points for the conduit through their tiny protrusion structure, thereby further improving the firmness and stability of the fixation;

[0047] Meanwhile, when the second fixing seat 4 is closed and forms a complete cylindrical cavity fixing conduit with the first fixing seat 3, the elastic force of the connecting spring 11 causes the fixing buckle 12 to be tightly engaged with the first through hole 13 on the first fixing seat 3; as the fixing buckle 12 moves, it gradually approaches and eventually enters the first through hole 13 to form a tight engagement, thereby firmly fixing the second fixing seat 4 in the closed position.

[0048] To secure the catheter clamp in a specific location, such as a patient's limb, a hospital bed, or an operating table, the user first inserts the catheter into the cylindrical cavity formed by the first fixing seat 3 and the second fixing seat 4, and then closes the second fixing seat 4. Subsequently, the end of the fixing strap 2 with the male Velcro 15 is wrapped around the object to be secured, and the male Velcro 15 is tightly attached to the female Velcro 16 on the other fixing strap 2. Due to the strong adhesive force between the male Velcro 15 and the female Velcro 16, they can quickly and firmly bond together, thereby securing the catheter clamp securely in the desired position.

[0049] To enhance user comfort and product heat dissipation, the fixing strap 2 and the receiving strap 1 are respectively designed with a first heat dissipation hole 17 and a second heat dissipation hole 18. These heat dissipation holes not only enhance the product's breathability but also provide unobstructed heat release channels, allowing users to experience a more comfortable user experience when using the catheter clamp for extended periods. In addition, the elastic material gives the fixing strap 2 good adaptability and comfort. Regardless of changes in the user's body shape or fixing position, the elastic fixing strap 2 can be flexibly adjusted to ensure that the catheter clamp is always kept in the correct position, while reducing user discomfort.
