[0002] Medical PFA tubing anti-bending structure is a functional structure used in medical settings to protect PFA tubing. Its core function is to prevent PFA tubing from bending, deforming, or becoming blocked due to external pressure or excessive bending during use, movement, or storage, thus ensuring the smooth transport of fluid within the tubing.

[0003] Existing PFA tubing anti-bending structures for medical use often lack effective positioning and angle limiting structures. The tubing is prone to excessive bending due to external forces or its own weight, which can obstruct fluid transport. Furthermore, the lack of flexible angle adjustment makes it difficult to adapt to the routing requirements of tubing in different medical scenarios, increasing the medical risks caused by tubing bending and affecting the safety and stability of the treatment process.

[0004] Therefore, a bend-resistant structure for medical PFA tubing is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A bend-resistant structure for medical PFA tubing includes a limiting structure 1, a tubing body 3 being snapped into the inner wall of the limiting structure 1, a rotating plate 4 being provided on the front side of the limiting structure 1, a rotating block 5 being provided on the inner wall of the rotating plate 4, a mounting bracket 6 being provided on the right side of the rotating block 5, and a mounting mechanism 2 being provided on the rear side of the mounting bracket 6. The inner wall of the mounting mechanism 2 is snapped into the surface of the tubing body 3. The mounting mechanism 2 includes a locking block 201, a rubber pad 202 being fixedly connected to the inner wall of the locking block 201, and a limiting tooth 203 being fixedly connected to the rear side of the locking block 201.

[0029] In this embodiment: by setting up an installation mechanism 2, the installation mechanism 2 can form a stable clamping connection with the pipeline body 3 through the cooperation of the locking block 201, the rubber pad 202, and the limiting tooth 203. The rubber pad 202 can buffer the clamping pressure to avoid damage to the surface of the pipeline body 3, while increasing the friction with the pipeline body 3 to prevent slippage. The limiting tooth 203 can further improve the clamping firmness, ensuring that the pipeline body 3 maintains the preset position after adjustment, effectively limiting excessive bending of the pipeline body 3, ensuring smooth fluid delivery, and adapting to the fixation of the pipeline body 3 in medical scenarios. For safety requirements, a limiting structure 1 is set up to provide initial snap-fit ​​positioning for the pipe body 3. The cooperation of the rotating plate 4 and the rotating block 5 realizes the angle adjustment function of the installation mechanism 2. The installation angle can be flexibly adjusted according to the routing requirements of the pipe body 3, so that the pipe body 3 is arranged within a reasonable bending range. The mounting bracket 6 provides stable support for the installation mechanism 2. The overall structure works together to adapt to different routings of the pipe body 3 according to the actual use scenario, avoiding excessive bending of the pipe body 3 due to disordered bending, and improving the reliability of the pipe body 3.

[0030] Specifically, such as Figure 1 , Figure 5 As shown, the inner wall of the rubber pad 202 is in contact with the surface of the pipe body 3, and the inner wall of the limiting tooth 203 is in contact with the surface of the pipe body 3.

[0031] Specifically, such as Figure 2 , Figure 6 As shown, a connecting block 7 is fixedly connected to the right side of the rotating block 5, and the right side of the connecting block 7 is fixedly connected to the left side of the mounting bracket 6.

[0032] Specifically, such as Figure 3 As shown, a fixing plate 8 is fixedly connected to the front side of the card block 201, and an insert block 9 is fixedly connected to the front side of the fixing plate 8.

[0033] In this embodiment: both the rubber pad 202 and the limiting tooth 203 are in contact with the surface of the pipe body 3. The rubber pad 202 avoids wear on the pipe body 3 through flexible contact, and the limiting tooth 203 enhances the snap-fit ​​stability through multi-point contact. The dual function ensures that the pipe body 3 is fixed reliably. The connecting block 7 on the right side of the rotating block 5 is fixed with the mounting bracket 6, providing a stable connection support for the installation mechanism 2 and preventing the installation mechanism 2 from shaking when adjusting the angle. The fixing plate 8 on the front side of the locking block 201 cooperates with the insertion block 9 to realize the quick installation of the installation mechanism 2 and the mounting bracket 6, improve the assembly accuracy of the overall structure, and facilitate user use.

[0034] Specifically, such as Figure 2 , Figure 3 As shown, the surface of the insert 9 is inserted into the inner wall of the mounting bracket 6, and the front side of the fixing plate 8 is in contact with the rear side of the mounting bracket 6.

[0035] Specifically, such as Figure 3 As shown, a knob 10 is movably connected to the inner wall of the mounting bracket 6, and the surface of the knob 10 is threadedly connected to the inner wall of the insert block 9.

[0036] In this embodiment: by setting the insert 9, the insert 9 is inserted into the inner wall of the mounting bracket 6 during use. Combined with the contact between the fixing plate 8 and the mounting bracket 6, the mounting mechanism 2 can be quickly positioned and installed. The knob 10 on the inner wall of the mounting bracket 6 is threadedly connected to the insert 9, which can further tighten the mounting mechanism 2 after insertion, preventing the mounting mechanism 2 from loosening and falling off during use. The two work together to improve the ease of disassembly and assembly of the mounting mechanism 2 (facilitating the replacement of mounting mechanisms 2 of different specifications) and the reliability of fixation.

[0037] Specifically, such as Figure 4 As shown, the inner wall of the mounting bracket 6 has a mounting hole 11 for use with the knob 10, and the inner wall of the mounting bracket 6 has a slot 12 for use with the insert block 9.

[0038] Specifically, such as Figure 6 As shown, a rotating shaft 13 is fixedly connected to the surface of the rotating block 5, and the surface of the rotating shaft 13 is rotatably connected to the inner wall of the rotating block 5.

[0039] Specifically, such as Figure 6 As shown, the inner wall of the rotating shaft 13 is threaded with a bolt 14, and the bottom of the bolt 14 is in close contact with the top of the rotating block 5.

[0040] Specifically, such as Figure 6 As shown, the inner wall of the rotating shaft 13 is provided with a threaded groove 15 for use with the bolt 14, and the inner wall of the rotating plate 4 is provided with a rotating hole 16 for use with the rotating shaft 13.

[0041] In this embodiment: the mounting hole 11 on the inner wall of the mounting bracket 6 facilitates the rotation of the knob 10 on the inner wall of the mounting bracket 6 through the mounting hole 11; the slot 12 on the inner wall of the mounting bracket 6 facilitates the insertion of the plug 9 into the inner wall of the mounting bracket 6 through the slot 12; the rotating shaft 13 is provided to fix the position of the rotating block 5 during use, facilitating the subsequent rotation of the rotating block 5 on the inner wall of the rotating plate 4 through the rotating shaft 13, which facilitates angle adjustment; the bolt 14 is provided to limit the rotation angle of the rotating shaft 13 during use, facilitating the appropriate angle limit between the limiting structure 1 and the mounting mechanism 2; the threaded groove 15 on the inner wall of the rotating shaft 13 facilitates the rotation of the bolt 14 on the inner wall of the rotating shaft 13 through the threaded groove 15; and the rotating hole 16 on the inner wall of the rotating plate 4 facilitates the rotation of the rotating shaft 13 on the inner wall of the rotating plate 4 through the rotating hole 16.

[0042] Working Principle: During the use of the limiting structure 1, the installation mechanism 2, through the cooperation of the locking block 201, rubber pad 202, and limiting tooth 203, can form a stable locking connection with the pipeline body 3. The rubber pad 202 can buffer the locking pressure to avoid damage to the surface of the pipeline body 3, while increasing the friction with the pipeline body 3 to prevent slippage. The limiting tooth 203 can further improve the locking firmness, ensuring that the pipeline body 3 maintains the preset position after adjustment, effectively limiting excessive bending of the pipeline body 3, ensuring smooth fluid delivery, and adapting to the requirements of medical scenarios for pipelines. To ensure the safety of the fixed body 3, a limiting structure 1 is set up. The limiting structure 1 provides initial snap-fit ​​positioning for the pipe body 3. The cooperation of the rotating plate 4 and the rotating block 5 realizes the angle adjustment function of the installation mechanism 2. The installation angle can be flexibly adjusted according to the direction requirements of the pipe body 3, so that the pipe body 3 is arranged within a reasonable bending range. The mounting bracket 6 provides stable support for the installation mechanism 2. The overall structure works together to adapt to different directions of the pipe body 3 according to the actual use scenario, avoiding excessive bending of the pipe body 3 due to disordered bending, and improving the reliability of the pipe body 3.
