Description

Technical Field

[0001] This utility model belongs to the field of catheter positioning technology, and more specifically, it relates to a neck catheter fixation component for dialysis. Background Technology

[0002] Generally, dialysis patients need to undergo dialysis 3 times a week at the medical center. Each treatment usually takes 3-5 hours and usually uses a dialysis central venous catheter (i.e., an indwelling catheter). This method can reduce the number of needle pricks and reduce the patient's pain.

[0003] Currently, there is no standardized device or method for securing temporary dialysis tubing in the neck. Clinical nurses typically use adhesive tape to attach the tubing to the skin around the patient's ear or neck based on their experience. However, this method, along with existing fixation devices, has issues such as poor safety, a high risk of infection for the patient, and an inability to effectively secure the dialysis tubing. Utility Model Content

[0004] The purpose of this invention is to provide a neck catheter fixation component for dialysis, which aims to solve the problem of the inability to effectively fix the dialysis catheter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: providing a neck catheter fixation assembly for dialysis, comprising: An adsorption membrane, wherein a through-hole is provided in the middle of the adsorption membrane to avoid the conduit; the adsorption membrane is used to adhere to the skin of the neck; A positioning sleeve is located outside the through hole and below the adsorption membrane; A connecting tube extends upward from the inner edge of the positioning sleeve and passes through the through hole; the connecting tube is used to limit the guide tube. A limiting sleeve is located on the side of the adsorption membrane away from the positioning sleeve. The limiting sleeve is threadedly connected to the connecting pipe, and the limiting sleeve and the positioning sleeve cooperate to clamp and position the connecting pipe.

[0006] In one possible implementation, a reinforcing ring is attached to the adsorption membrane, the reinforcing ring being located outside the through hole; the limiting sleeve and the positioning sleeve are distributed on both sides of the reinforcing ring.

[0007] In one possible implementation, the connecting tube and the positioning sleeve are integrally formed.

[0008] In one possible implementation, the inner surface of the positioning sleeve is provided with a disinfection ring.

[0009] In one possible implementation, the inner side of the positioning sleeve is provided with a relief groove to accommodate the disinfection ring, and the disinfection ring is adhered to the relief groove.

[0010] In one possible implementation, the disinfection ring extends from the positioning sleeve into the inner cavity of the connecting tube.

[0011] In one possible implementation, the disinfection ring has multiple pores for adsorbing and storing liquid.

[0012] In one possible implementation, the limiting sleeve, the positioning sleeve, and the connecting tube are all made of transparent material.

[0013] In one possible implementation, the inner side of the connecting tube is provided with a plurality of positioning posts, which cooperate to position the conduit.

[0014] In one possible implementation, an adhesive ring is detachably connected to the inner side of the positioning sleeve.

[0015] The advantages of the dialysis neck catheter fixation assembly provided by this utility model are as follows: Compared with the prior art, in this utility model, the through hole is opened in the middle of the adsorption membrane, and the positioning sleeve is set below the adsorption membrane. The connecting tube extends upward from the inner edge of the positioning sleeve and passes through the through hole. The limiting sleeve is located on the side of the adsorption membrane away from the positioning sleeve.

[0016] In practical applications, the adsorption membrane is adhered to the skin of the neck, and then the limiting sleeve is threadedly connected to the connecting tube.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1 The present invention provides a neck catheter fixation assembly for dialysis. The neck catheter fixation assembly for dialysis includes: an adsorption membrane 1, a positioning sleeve 2, a connecting tube 7, and a limiting sleeve 3. The adsorption membrane 1 has a through hole in its center to allow the catheter to pass through; the adsorption membrane 1 is used to adhere to the skin of the neck. The positioning sleeve 2 is located outside the through hole and below the adsorption membrane 1. The connecting tube 7 extends upward from the inner edge of the positioning sleeve 2 and passes through the through hole; the connecting tube 7 is used to limit the catheter. The limiting sleeve 3 is located on the side of the adsorption membrane 1 away from the positioning sleeve 2; the limiting sleeve 3 is threadedly connected to the connecting tube 7, and the limiting sleeve 3 cooperates with the positioning sleeve 2 to clamp and position the connecting tube 7.

[0022] The beneficial effects of the dialysis neck catheter fixation assembly provided by this utility model are as follows: Compared with the prior art, in this utility model, the through hole in the dialysis neck catheter fixation assembly is opened in the middle of the adsorption membrane 1, and the positioning sleeve 2 is set below the adsorption membrane 1. The connecting tube 7 extends upward from the inner edge of the positioning sleeve 2 and passes through the through hole. The limiting sleeve 3 is located on the side of the adsorption membrane 1 away from the positioning sleeve 2.

[0023] In practical applications, the adsorption membrane 1 is adhered to the skin of the neck, and then the limiting sleeve 3 is threadedly connected to the connecting tube 7. Finally, the positioning sleeve 2, in conjunction with the limiting sleeve 3, clamps the adsorption membrane 1, thereby achieving the positioning of the connecting tube 7 with the help of the adsorption membrane 1. After the connecting tube 7 is positioned, the position of the catheter is determined. The structure of this application is relatively simple, easy to use, and can achieve stable positioning of the catheter, avoiding problems such as catheter misalignment. More importantly, it can be used multiple times, saving costs.

[0024] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 A reinforcing ring 6 is attached to the adsorption membrane 1, and the reinforcing ring 6 is located outside the through hole; the limiting sleeve 3 and the positioning sleeve 2 are distributed on both sides of the reinforcing ring 6. The adsorption membrane 1 is relatively thin and is prone to plastic deformation. The reinforcing ring 6 is bonded or integrally formed on the adsorption membrane 1. At this time, the limiting sleeve 3 and the positioning sleeve 2 are clamped on both sides of the reinforcing ring 6, and the reinforcing ring 6 is positioned on the skin with the help of the adsorption membrane 1.

[0025] In practical applications, the positioning sleeve 2 is first initially positioned at a designated location, and the catheter is passed through the connecting tube 7. Then, the adsorption membrane 1 is accurately adhered to the skin of the neck, ensuring that the through-hole precisely avoids the catheter. At this point, the adsorption membrane 1 covers and effectively limits the positioning sleeve 2. When it is necessary to position and fix the connecting tube 7, the limiting sleeve 3 is installed on the side of the adsorption membrane 1 away from the positioning sleeve 2 and threadedly connected to the connecting tube 7. As the limiting sleeve 3 is tightened, the limiting sleeve 3 and the positioning sleeve 2 cooperate to gradually clamp the reinforcing ring 6, making the connecting tube 7 more securely fixed in the predetermined position, thereby ensuring the stability and reliability of the entire system and providing a solid foundation and guarantee for related medical or experimental operations.

[0026] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 The connecting tube 7 and the positioning sleeve 2 are integrally molded. This design makes the entire assembly more structurally stable, reducing potential loosening or displacement issues caused by component connections. The integrally molded connecting tube 7 and positioning sleeve 2 work together more effectively, ensuring the stability and safety of the catheter during fixation. Simultaneously, this integrated design facilitates manufacturing, improves production efficiency, and reduces production costs. Furthermore, during long-term use, the integrally molded structure better resists various external forces, reducing the likelihood of damage or failure, thus providing a more reliable guarantee for dialysis treatment.

[0027] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 The inner surface of the positioning sleeve 2 is equipped with a disinfection ring 5. The disinfection ring 5 has a certain height, and its design prevents external bacteria from entering the body through gaps and surgical openings in the neck. The disinfection ring 5 stores a certain amount of disinfectant. When the neck catheter needs to be fixed and disinfected, the absorbent membrane 1 is first adhered to the neck skin. Then, the connecting tube 7 extends upwards from the inner edge of the positioning sleeve 2 and passes through the through-hole. The catheter is then placed inside the connecting tube 7. At this time, the disinfection ring 5 on the inner surface of the positioning sleeve 2 functions, and the disinfectant continuously disinfects the area where the catheter contacts the neck skin and the surrounding area, preventing external bacteria from entering. Over time, the disinfectant will gradually evaporate or be consumed. New disinfectant can be added to the disinfection ring 5 through a specific filling port to ensure the durability of the disinfection effect. After the limiting sleeve 3 is threadedly connected to the connecting tube 7, it works with the positioning sleeve 2 to clamp the reinforcing ring 6, thereby firmly fixing the entire dialysis neck catheter fixation assembly to the neck. This achieves both fixation and ensures the hygiene and safety of the neck catheter fixation site through the disinfection ring 5.

[0028] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1The inner side of the positioning sleeve 2 is provided with a relief groove to accommodate the disinfection ring 5, and the disinfection ring 5 is adhered within the relief groove. The relief groove is mainly designed to accommodate the disinfection ring 5, preventing excessive pressure between the disinfection ring 5 and the skin. The presence of the relief groove also facilitates the replacement and maintenance of the disinfection ring 5. After a period of use, the disinfection ring 5 can be easily removed from the relief groove for replacement, ensuring the continued effectiveness of disinfection. In addition, the design of the relief groove makes the entire dialysis neck catheter fixation assembly more compact and reasonable, and the presence of the disinfection ring 5 will not affect the normal operation and installation of other components.

[0029] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 The disinfection ring 5 extends from the positioning sleeve 2 into the inner lumen of the connecting tube 7. By extending the disinfection ring 5 upwards, bacteria can be prevented from entering the body through the gap between the positioning sleeve 2 and the catheter, thus preventing infection. Simultaneously, the disinfection ring 5 can be made of materials with good disinfection properties and harmless to the human body, such as polymer materials containing silver ions. This allows it to continuously release bactericidal substances as it extends to the gap between the positioning sleeve 2 and the catheter, further enhancing its inhibitory effect on bacteria and effectively ensuring the safety and hygiene of the dialysis treatment process. Furthermore, the extension length of the disinfection ring 5 can be designed and adjusted according to actual needs to ensure optimal disinfection effects in different usage scenarios, providing more reliable protection for patients' dialysis treatment.

[0030] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 The disinfection ring 5 contains multiple pores for adsorbing and storing liquids. These pores serve two purposes: adsorbing the disinfectant solution and absorbing any fluids such as blood that may flow out. The even distribution of these pores ensures that the disinfectant solution fully contacts all areas of the neck skin during disinfection, improving the disinfection effect. Simultaneously, when blood or other fluids flow out, the pores quickly absorb them, preventing fluid accumulation on the neck skin surface and reducing the risk of infection. Furthermore, the size and shape of the pores are carefully designed to effectively adsorb and store liquids without compromising the structural strength and stability of the disinfection ring 5, ensuring its reliability and safety during use.

[0031] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1The limiting sleeve 3, positioning sleeve 2, and connecting tube 7 are all made of transparent material. This design allows medical staff to clearly observe the position and status of the internal catheter when using the dialysis neck catheter fixation assembly, facilitating timely detection of catheter displacement and other issues, thus more effectively ensuring the safety and stability of dialysis treatment. Simultaneously, the transparent material does not obstruct the normal use of the catheter and does not affect its function. Furthermore, the transparent material facilitates cleaning and disinfection of the entire fixation assembly, maintaining its hygiene and providing better protection for the patient's treatment.

[0032] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 The connecting tube 7 has multiple positioning posts 4 on its inner side, which work together to position the catheter. These positioning posts 4 ensure the stability of the relative position between the catheter and the connecting tube 7. These positioning posts 4 are evenly distributed on the inner wall of the connecting tube 7, and their shape and size are carefully designed to fit tightly against the outer wall of the catheter. When the catheter is inserted into the connecting tube 7, the positioning posts 4 automatically contact specific positions on the catheter, preventing the catheter from shaking or moving within the connecting tube 7. This precise positioning function not only improves the safety and stability of dialysis treatment but also reduces friction and wear between the catheter and the connecting tube 7, extending the catheter's lifespan. Furthermore, the design of the positioning posts 4 facilitates catheter positioning and adjustment by physicians during dialysis procedures, improving operational convenience and efficiency.

[0033] For some embodiments of the dialysis neck catheter fixation assembly provided in this application, please refer to... Figure 1 An adhesive ring 8 is detachably connected to the inner side of the positioning sleeve 2. The adhesive ring 8 is snapped onto the positioning sleeve 2 and has an adhesive film. Replacing the adhesive ring 8 strengthens the adhesion between the positioning sleeve 2 and the skin. Specifically, when the adhesive ring 8 needs to be replaced, simply remove the original adhesive ring 8 from the inner side of the positioning sleeve 2 and then snap the new adhesive ring 8 into the corresponding position on the positioning sleeve 2. The adhesive film on the new adhesive ring 8 has different adhesive properties or materials, providing a more suitable adhesion effect according to different patients' skin conditions or usage needs. This further improves the stability and comfort of the entire dialysis neck catheter fixation assembly, avoiding problems such as weak adhesion or skin allergies that could affect the normal progress of dialysis treatment.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
