Description

Technical Field

[0001] This utility model relates to the field of fixation clip technology, and more specifically, to a medical catheter fixation clip that can be quickly adjusted. Background Technology

[0002] In modern medical systems, medical catheters have become indispensable key instruments in clinical treatment. From basic intravenous infusion therapy to complex surgical drainage, and then to delicate cardiovascular intervention and neurosurgical anesthesia procedures, medical catheters undertake important missions such as delivering drugs, draining accumulated fluids, and monitoring physiological parameters.

[0003] Currently, the methods used to fix medical catheters in clinical practice have revealed some drawbacks. For example, the simple adhesive tape fixation method, although seemingly simple to operate, has many problems in actual application. On the one hand, the process of applying the adhesive tape is time-consuming and laborious. Medical staff need to carefully measure and cut the tape and ensure that its placement on the patient's skin is accurate, which undoubtedly increases the workload of medical staff in busy clinical work. On the other hand, after the tape is applied, the fixation position and angle of the catheter are also limited, making it difficult to adjust conveniently later. If adjustment is needed, the tape needs to be torn off and reapplied. Repeated application can cause traction damage to the skin and affect the effectiveness of the treatment.

[0004] While some medical catheter clamps address some of the issues associated with adhesive tape fixation, their adjustment mechanisms often suffer from design flaws. For instance, some clamps employ complex knob and bolt structures to adjust catheter position, requiring medical staff to use additional tools and go through multiple cumbersome steps. This significantly impacts treatment efficiency in time-sensitive emergency medical scenarios, such as emergency resuscitation and handling intraoperative emergencies. Therefore, we propose a rapidly adjustable medical catheter clamp. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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. Please see Figures 1-4This utility model provides a technical solution: a medical catheter fixing clip that can be quickly adjusted, including an adhesive patch 1. A support 2 is fixedly installed at the center of the upper surface of the adhesive patch 1. An annular groove 20 is provided inside the support 2. Multiple locking holes 22 communicating with the outside are provided on the annular groove wall of the annular groove 20. An exit hole 21 communicating with the outside is provided at the center of the top wall of the annular groove 20. A turntable 3 is rotatably connected inside the annular groove 20. An annular sliding groove 30 is provided on the annular side of the turntable 3. A sliding column 302 is slidably connected inside the annular sliding groove 30. The sliding column 302 is engaged with the locking holes 22. A spring 301 is fixedly installed between the sliding column 302 and the rear side wall of the annular sliding groove 30. A spring 301 is fixedly installed on the top surface of the turntable 3. A protruding post 31 is fixedly installed, passing through and rotatably connected to the through hole 21. When an external force is applied to the sliding post 302, the sliding post 302 compresses the spring 301 and slides within the annular groove 30, disengaging from the current locking hole 22. The turntable 3 can rotate around the annular groove 20. When the sliding post 302 is aligned with the next locking hole 22, the sliding post 302 is locked into the corresponding locking hole 22 under the action of the spring 301, so that the fixing clamp can be adjusted at multiple angles and stably positioned after adjustment. The size of the turntable 3 is adapted to the size of the annular groove 20, and the size of the protruding post 31 is adapted to the size of the through hole 21. The adapted size of the turntable 3 and the annular groove 20, and the protruding post 31 and the through hole 21, ensures the smoothness and stability of the structure operation.

[0018] In this embodiment, a mounting base 32 is fixedly installed on the top surface of the protruding post 31. A mounting chamber 321 is provided inside the mounting base 32. A mounting hole 322 communicating with the outside is provided on one side wall of the mounting chamber 321, so that the catheter can be inserted into the mounting chamber 321 through the mounting hole 322 to complete the catheter placement operation.

[0019] Specifically, an anti-allergy adhesive layer 10 is provided on the bottom surface of the adhesive patch 1, which reduces the risk of skin allergies in patients and ensures safe use; a release film 11 is provided on the surface of the anti-allergy adhesive layer 10, and a tear-off end 12 is integrally formed on the release film 11. The lower projection of the tear-off end 12 is located outside the lower projection of the adhesive patch 1, allowing medical staff to easily peel off the release film 11 and quickly stick the fixation clip to the appropriate part of the patient, simplifying the installation process.

[0020] Furthermore, a ball head 303 is fixedly installed on the outer end of the sliding column 302. The ball head 303 is hemispherical. The ball head 303 can prevent the thumb from being scratched when squeezing the ball head 303. It also ensures that the ball head 303 can be inserted more smoothly along the locking hole 22. In addition, it reduces the wear when the sliding column 302 is engaged with the locking hole 22 and extends the service life.

[0021] In addition, an elastic rubber plate 33 is fixedly installed on the bottom wall of the snap-fit ​​chamber 321. The elastic rubber plate 33 is made of elastic rubber and can deform under force. After the external force is removed, it can return to its original shape. An extension plate 34 is fixedly installed on the top of the elastic rubber plate 33, and a clamping plate 35 is fixedly installed on the top of the extension plate 34. An anti-slip layer 351 is provided on the upper surface of the clamping plate 35 so that the clamping plate 35 can press the tube against the top wall of the snap-fit ​​chamber 321. At the same time, because the elastic rubber plate 33 is elastic, it can adaptively adjust according to the diameter of the tube, enhance the friction with the tube, and firmly fix the tube. The force of the elastic rubber plate 33 squeezing the tube is less than the force of the tube deformation, so that the clamping plate 35 will not completely flatten the tube, ensuring smoother liquid flow.

[0022] It is worth noting that a cover sleeve 36 is fixedly installed on one side of the card holder 32. The side of the cover sleeve 36 away from the card holder 32 is provided with multiple winding holes 361, which can be used with straps to further fix the conduit, improve the reliability of the fixation, and meet the needs of conduit fixation in different scenarios. When using the quick-adjustable medical catheter clamp of this utility model, medical staff pinch and tear open the end 12, remove the release film 11, and stick the anti-allergy adhesive layer 10 at the bottom of the adhesive patch 1 to the appropriate part of the patient's body to avoid skin allergies. Next, adjust the angle of the catheter fixing clamp. Press the ball head 303 at the outer end of the sliding column 302 with your thumb. The sliding column 302 compresses the spring 301 and is stored in the annular groove 30, disengaging from the current locking hole 22. Rotate the turntable 3, which is rotatably connected to the annular groove 20, to a suitable angle so that the sliding column 302 is aligned with the corresponding locking hole 22. Under the action of the spring 301, the sliding column 302 is locked into the corresponding locking hole 22, realizing multi-angle adjustment and fixing of the fixing clamp. Then, the conduit is fixed and inserted into the snap-fit ​​chamber 321 of the snap-fit ​​seat 32 through the snap-fit ​​hole 322. The elastic rubber plate 33, extension plate 34 and clamping plate 35 on the bottom wall of the snap-fit ​​chamber 321 will adapt to the conduit diameter. The anti-slip layer 351 on the clamping plate 35 increases the friction. The clamping plate 35 presses the conduit against the top wall of the snap-fit ​​chamber 321 to complete the fixing operation. At this time, after squeezing the clamping plate 35 inward, the conduit can move left and right to adjust the fixed part of the conduit. Finally, the conduit can be further fixed by passing the strap through the winding hole 361 on the cover sleeve 36 to meet the needs of different scenarios.
