Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a catheter fixator. Background Technology

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. Through diffusion / convection, substances are exchanged to remove metabolic waste, maintain electrolyte and acid-base balance, and remove excess water. The entire process of returning the purified blood to the body is called hemodialysis. During intrajournal dialysis, a temporary dialysis catheter is generally used and is inserted through the jugular vein.

[0003] Currently, most temporary cervical catheter fixation methods involve using homemade ropes to loop and secure them to the head, or using tape to stick them to the skin. These methods are prone to getting dirty and are unsightly, easily causing patients to feel ashamed or embarrassed. Furthermore, improper fixation can easily lead to the catheter shifting or being pulled out, resulting in poor fixation. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A catheter fixator includes a fixing mechanism and a clamping mechanism. The fixing mechanism includes a hanging ear, the inside of which is provided with a groove. A support bar is movably engaged inside the groove. A connecting rod is fixedly connected to the rear end of the hanging ear. A connecting surface is provided on the rear side of the connecting rod. The clamping mechanism is fixedly connected to the rear side of the connecting surface.

[0006] A further improvement of the present invention is that the clamping mechanism includes a support block and an outer clamping plate. A slot is provided on the rear side of the support block. A fixing block is fixedly connected to the outer side of the rear side of the support block. A rotating shaft is movably engaged inside the outer clamping plate. The rotating shaft is movably hinged to the inner side of the fixing block. A torsion spring located inside the fixing block and the outer clamping plate is movably installed on the outside of the rotating shaft.

[0007] A further improvement of this utility model is that the ear hook is designed in an arc shape that fits the ear root.

[0008] A further improvement of this utility model is that the support bar is made of an elastic alloy.

[0009] A further improvement of this utility model is that the ear loop is made of silicone.

[0010] A further improvement of this utility model is that the slots are symmetrically arranged on the left and right sides of the support block.

[0011] A further improvement of this utility model is that the outer clamping plate is arranged in an arc shape to match the slot.

[0012] A further improvement of this utility model is that a lever is fixedly connected to the outer side of the outer clamping plate.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides a catheter fixator, which has a support strip inside the ear loop. The support strip is made of elastic alloy. The elastic alloy has the property of restoring its shape after deformation. It is used in conjunction with the arc-shaped ear loop to lock into place at the root of the ear. The support strip clamps and fixes the catheter. The temporary catheter is fixed to the rear side of the docking surface by the tube clamping mechanism. The device is easy to use, easy to put on and take off. It can also be well hidden at the root of the ear, making it more aesthetically pleasing and providing a modesty effect for the patient.

[0015] 2. This utility model provides a catheter fixator. By moving the lever outward, the lever rotates outward along the inner side of the fixing block and twists the torsion spring. The temporary catheter is then secured in the slot. After the lever is released, the outer clamp rotates inward under the restoring force of the torsion spring and is secured in the slot. This fixes the temporary catheter in the slot, making it easier to fix and disassemble the temporary catheter and improving the convenience of use. Attached Figure Description

[0022] The present invention will now be described in further detail:

[0023] like Figures 1 to 5 As shown, this utility model provides a catheter fixator, including a fixing mechanism 1 and a clamping mechanism 2. The fixing mechanism 1 includes a hanging ear 11, the inside of which is provided with a slot 12. A support bar 13 is movably engaged inside the slot 12. A docking rod 14 is fixedly connected to the rear end of the hanging ear 11. A docking surface 15 is provided on the rear side of the docking rod 14. The clamping mechanism 2 is fixedly connected to the rear side of the docking surface 15.

[0024] The ear loop 11 has an internal support strip 13, which is made of elastic alloy. Its deformation recovery property, combined with the arc-shaped ear loop 11, allows it to be locked at the ear root. The support strip 13 clamps and fixes it in place. The temporary catheter is fixed to the rear side of the docking surface 15 by the clamping mechanism 2. The whole system is easy to use, convenient to wear and remove, and can be well hidden at the ear root, making it more aesthetically pleasing and providing a sense of modesty for the patient.

[0025] like Figure 4 and Figure 5 As shown, the clamping mechanism 2 includes a support block 21 and an outer clamping plate 25. A slot 22 is provided on the rear side of the support block 21. A fixing block 23 is fixedly connected to the outer side of the rear side of the support block 21. A rotating shaft 24 is movably clamped inside the outer clamping plate 25. The rotating shaft 24 is movably hinged to the inner side of the fixing block 23. A torsion spring 26 located inside the fixing block 23 and the outer clamping plate 25 is movably installed on the outside of the rotating shaft 24.

[0026] By moving the lever 27 outward, the lever 27 rotates outward along the inner side of the fixing block 23 and twists the torsion spring 26. This causes the temporary conduit to be locked in the slot 22. After the lever 27 is released, the outer clamp 25 rotates inward under the restoring force of the torsion spring 26 and locks in the slot 22. This limits and fixes the temporary conduit in the slot 22, making it easier to fix and disassemble the temporary conduit and improving the ease of use.

[0027] like Figure 2 As shown, the ear hook 11 is designed in an arc shape that fits the base of the ear.

[0028] By making the ear loop 11 fit the shape of the ear root, it can be ensured that the ear loop 11 fits snugly at the ear root for wearing and fixation, thus improving the overall aesthetics.

[0029] like Figure 3 As shown, the support bar 13 is made of elastic alloy.

[0030] The support bar 13, made of an elastic alloy such as nickel-titanium alloy or titanium alloy, can deform to clamp the ear loop 11 at the ear root position, ensuring the stability of the fixation.

[0031] like Figure 3 As shown, the ear loop 11 is made of silicone.

[0032] The ear loops 11 are made of silicone, which provides a soft touch to the skin, reducing discomfort, while increasing friction to improve wearing stability.

[0033] like Figure 4 As shown, the card slots 22 are symmetrically arranged on the left and right sides of the support block 21.

[0034] The temporary conduit can be fixed separately by the symmetrically arranged slots 22, ensuring the stability of the fixation.

[0035] like Figure 4 As shown, the outer clamping plate 25 is arranged in an arc shape to match the slot 22.

[0036] The outer clamp 25 is designed in an arc shape to work with the slot 22 to secure the temporary conduit, thereby fixing the temporary conduit in place.

[0037] like Figure 5 As shown, a lever plate 27 is fixedly connected to the outer side of the outer clamping plate 25.

[0038] The setting of the dial plate 27 allows for easy movement of the outer clamp plate 25, thus facilitating the fixing or disassembly of the temporary conduit.

[0039] The working principle of this catheter fixator will be explained in detail below.

[0040] like Figures 1 to 5 As shown, by wearing the fixing mechanism 1 on the ear, the support bar 13 is stretched and deformed, and the ear hook 11 is clipped to the root of the patient's ear. The force generated by the restoration of the support bar 13 clamps the ear. The two temporary catheters are fixed by the clamping mechanism 2 fixed to the rear side of the mating surface 15. By moving the lever 27 outward, the lever 27 drives the outer clamp 25 to rotate the rotating shaft 24 outward along the inner side of the fixing block 23. Since the torsion spring 26 is locked in the outer clamp 25 and the fixing block 23, the outer clamp 25 rotates around the fixing block 23. When the fixed block 23 rotates relative to the torsion spring 26, the outer clamp 25 moves outward, opening the rear side of the slot 22. The temporary catheter is then secured in the slot 22. After the lever 27 is released, the outer clamp 25 rotates inward along the fixed block 23 under the restoring elastic force of the torsion spring 26 and is secured in the slot 22. The temporary catheter is then fixed in the slot 22. The above operation can fix the two temporary catheters in the slot 22 respectively. This makes it easy to fix the catheters while the ear-hook design makes the patient look better and can cover up their private parts.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
