Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically, to a dialysis catheter dressing. Background Art
[0002] Hemodialysis, one of the primary renal replacement therapies for patients with renal failure, relies on draining blood from the patient's body through a dialyzer composed of numerous hollow fibers. Within the dialyzer, the blood exchanges substances with a solution containing electrolytes similar to those in the body (dialysate). Through diffusion, ultrafiltration, adsorption, and convection, the dialyzer removes metabolic waste and maintains electrolyte and acid-base balance. This process is crucial to maintaining the patient's life and health.
[0003] However, hemodialysis places high demands on the reliability and stability of vascular access. Because some patients' upper limb vascular conditions are poor, establishing a long-lasting and stable native arteriovenous fistula is impossible. Therefore, hemodialysis catheters are required to establish vascular access. These catheters must remain in the patient's body for extended periods, making their maintenance and management particularly crucial.
[0004] During catheter use, a dressing is often applied near the catheter to prevent infection and maintain its position. This dressing is not only waterproof but also provides some protection from external contamination or damage. However, traditional dressings present several challenges, such as awkward operation, poor retention, and skin irritation. Therefore, there is a need to develop new, specialized dressings for dialysis that address these issues. Utility Model Content

[0035] The dialysis catheter dressing 100 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0036] like Figure 1 and Figure 2 As shown, a dialysis catheter dressing 100 according to an embodiment of the present invention includes an dressing body 10 , a plurality of adhesive bodies 20 and a plurality of sealing bodies 30 .
[0037] Specifically, the side of the applicator body 10 facing the user's skin is provided with an antibacterial layer 11 coated with a volatile antibacterial substance. Multiple adhesive bodies 20 are spaced around the periphery of the applicator body 10 to secure the applicator body 10 to the user's skin. Seals 30, made of elastic material, are each positioned at the connection between the adhesive body 20 and the applicator body 10 to enhance the seal between the applicator body 10 and the user's skin. A fastener 40 is provided on the side of the applicator body 10 facing away from the seals 30 to secure the dialysis catheter.
[0038] In other words, if Figure 1As shown, the dialysis catheter patch 100 according to an embodiment of the present invention is mainly composed of an applicator body 10, a plurality of adhesive bodies 20 and a plurality of sealing bodies 30. Among them, an antibacterial layer 11 is provided on the side of the applicator body 10 facing the user's skin. The antibacterial layer 11 can be coated with a volatile antibacterial substance, which can further prevent the patient from being infected and ensure the safety of the patient's use. In the present utility model, the applicator body 10 is breathable and can prevent dust from entering. The antibacterial layer 11 on the applicator body 10 contains an antibacterial agent, which can prevent infection. A plurality of adhesive bodies 20 are spaced apart and arranged around the periphery of the applicator body 10, and the adhesive bodies 20 have an anti-allergic effect. The adhesive body 20 is mainly used to fix the applicator body 10 on the user's skin, which is convenient for fixing the applicator body 10 and easy to use.
[0039] The sealing body 30 can be made of elastic material, and each sealing body 30 is respectively arranged at the connection position between the adhesive body 20 and the application body 10, thereby increasing the sealing between the application body 10 and the user's skin and reducing the influx of external bacteria. Figure 2 As shown, a fixing member 40 is provided on the side of the dressing body 10 facing away from the sealing body 30. The dialysis catheter is fixed by the fixing member 40 to prevent the dialysis catheter from shifting, thereby further ensuring treatment safety.
[0040] It should be noted that the core requirements of hemodialysis technology are to effectively remove metabolic waste from the patient's body, maintain electrolyte and acid-base balance, and ensure the safety and comfort of the treatment process. However, in the existing technology, the use and maintenance of hemodialysis catheters are plagued by a series of problems.
[0041] First, due to poor vascular conditions in some patients, vascular access requires hemodialysis catheters. However, prolonged indwelling of catheters can lead to infection, primarily because the skin near the catheter is susceptible to contamination by external bacteria, and traditional dressings may not provide adequate protection. Furthermore, poor dressing fixation can cause the catheter to shift or fall out, further increasing the risk of infection.
[0042] Secondly, the design and operation of existing dressings can also affect patient comfort. For example, some dressings require finger pressure to stop bleeding, which not only increases the patient's pain but also makes it difficult to control the pressure, potentially resulting in poor hemostasis. Furthermore, the large number of dressing components and complex structure make it difficult for patients to put on and take off clothes daily, increasing the risk of the dressing accidentally falling off.
[0043] Third, the risk of infection during hemodialysis is also a significant concern. Because dialysis treatments require frequent procedures, patients and healthcare workers face a high risk of infection, particularly blood-borne infections such as hepatitis B and C. This not only impacts patient outcomes but also potentially increases medical costs and the burden on society.
[0044] To address these shortcomings of the existing technology, the present invention aims to provide a more advanced and practical dialysis dressing. By improving the dressing's materials and design, this new dressing enhances its skin fit and retention, effectively preventing catheter infection and displacement. Furthermore, the present invention aims to simplify the dressing's operation and replacement process, alleviating pain and inconvenience for patients. Furthermore, by optimizing the operating procedures and disinfection measures during hemodialysis, the invention aims to reduce the risk of infection and improve the safety and effectiveness of treatment.
[0045] Therefore, according to the dialysis catheter patch 100 of the embodiment of the present invention, an adhesive body 20 is provided on the periphery of the patch body 10 to fix the patch body 10 on the patient's skin, which is very convenient to use. An antibacterial layer 11 coated with a volatile antibacterial substance is provided on the patch body 10, which can further prevent the patient from being infected and ensure the safety of the patient's use. At the same time, by providing a sealing body 30, the sealing performance of the dialysis catheter patch 100 is improved, and the influx of external bacteria is reduced. The dialysis catheter can be fixed by a fixing member 40 to prevent the dialysis catheter from shifting, further ensuring the safety of treatment. The dialysis catheter patch 100 has a simple overall design, is easy to use, is comfortable, and has high reliability.
[0046] According to an embodiment of the present invention, the dressing body 10 includes multiple dustproof layers, which are stacked in sequence, and the antibacterial layer 11 is provided on the dustproof layer facing the user's skin.
[0047] That is to say, if Figure 1 As shown, the dressing body 10 includes multiple dustproof layers, which can be stacked in sequence, and the antibacterial layer 11 is arranged on the dustproof layer facing the user's skin. By setting the dustproof layer, dust in the external environment can be effectively prevented, reducing the risk of infection.
[0048] In some specific embodiments of the present invention, the patch body 10 is a square body, and the antibacterial layer 11 extends along the circumference of the patch body 10. The length of the patch body 10 is 5-10 cm.
[0049] In other words, if Figure 1 As shown, the patch body 10 can be designed as a square body, and the antibacterial layer 11 can extend along the circumference of the patch body 10. By extending a circle of antibacterial layer 11 around the circumference of the patch body 10, a good sterilization effect is achieved during the volatilization of the antibacterial substance in the antibacterial layer 11, thereby preventing bacteria from infecting the patient and improving the safety of the patient's treatment. The length of the patch body 10 can be 5-10 cm. For example, the length of the patch body 10 can be 8 cm, which is of suitable size and convenient for patients to use. Of course, the specific shape and size of the patch body 10 can be specifically set according to actual needs, and will not be described in detail in this utility model.
[0050] In some embodiments of the present invention, the adhesive body 20 is an elastomer. Air holes are provided within the adhesive body 20. The cross-sectional dimensions of the central region of the adhesive body 20 are smaller than the cross-sectional dimensions of the ends of the adhesive body 20. The cross-sectional dimensions of the ends of the adhesive body 20 are 5-10 cm, while the cross-sectional dimensions of the central region of the adhesive body 20 are 3-5 cm.
[0051] That is to say, if Figure 1 As shown, the adhesive body 20 can be made of an elastomer, which makes it easier for the patient to stretch the adhesive body 20 according to their individual needs, thereby improving the adaptability of the dialysis catheter patch 100. Air holes are provided in the adhesive body 20 to facilitate the timely discharge of sweat and other substances from the patient's skin, providing a good environment for the treatment area of the patient's skin. The cross-sectional dimensions of the middle area of the adhesive body 20 are smaller than the cross-sectional dimensions of the two ends of the adhesive body 20. The adhesive body 20 can be roughly configured into a funnel shape with wide ends and narrow middle, which is convenient for patients to use and can also reduce material costs. The cross-sectional dimensions of the two ends of the adhesive body 20 are 5-10 cm, for example, the cross-sectional dimensions of the two ends of the adhesive body 20 are 8 cm. The cross-sectional dimensions of the middle area of the adhesive body 20 are 3-5 cm, for example, the cross-sectional dimensions of the middle area of the adhesive body 20 are 4 cm, which are of appropriate size and convenient for patients to use. Of course, the specific shape and size of the adhesive body 20 can be specifically set according to actual needs and will not be described in detail in this utility model.
[0052] According to one embodiment of the present invention, Figure 1 As shown, there may be four adhesive bodies 20, which are respectively arranged on the four sides of the dressing body 10, and a sealing body 30 is arranged between two adjacent adhesive bodies 20 to ensure the sealing of the dialysis catheter dressing 100 and prevent external bacteria from pouring in.
[0053] According to one embodiment of the present invention, Figure 2 As shown, the fixing member 40 can be a fixing patch, and the dialysis catheter is fixed by the fixing patch, which facilitates the fixation of the dialysis catheter, is convenient to use, has a good fixing effect, and effectively prevents the dialysis catheter from shifting or falling off. Of course, the shape and specific arrangement of the fixing patch can be specifically limited according to actual needs and will not be described in detail in this utility model.
[0054] The dialysis catheter dressing 100 of this invention addresses the issues of poor sealing and fixation in existing hemodialysis dressings. By employing novel materials and designs, it significantly improves the sealing and fixation of the dressing. This not only effectively prevents bacterial intrusion around the catheter, reducing the risk of infection, but also minimizes the possibility of catheter displacement or dislodgement, ensuring safe treatment.
[0055] Secondly, this utility model focuses on enhancing patient comfort. By optimizing the structure and operation of the dressing, the replacement process is simplified, reducing patient discomfort. Furthermore, the reduced number of dressing components and simplified construction make daily dressing and undressing more convenient for patients, further enhancing their comfort.
[0056] In addition, the utility model also reduces the risk of infection during hemodialysis by optimizing the operating procedures and disinfection measures, which helps to ensure the treatment effect of patients and reduce medical costs and social burdens.
[0057] In summary, according to the dialysis catheter patch 100 of the embodiment of the present invention, an adhesive body 20 is provided on the periphery of the patch body 10 to fix the patch body 10 on the patient's skin, which is very convenient to use. An antibacterial layer 11 coated with a volatile antibacterial substance is provided on the patch body 10, which can further prevent the patient from being infected and ensure the safety of the patient. At the same time, by providing a sealing body 30, the sealing performance of the dialysis catheter patch 100 is improved, and the influx of external bacteria is reduced. The dialysis catheter can be fixed by a fixing member 40 to prevent the dialysis catheter from shifting, further ensuring the safety of treatment. The dialysis catheter patch 100 has a simple overall design, is easy to use, is comfortable, and has high reliability.
[0058] Of course, for those skilled in the art, other structures and principles of the dialysis catheter dressing 100 are understandable and achievable, and will not be described in detail in the present invention.
[0059] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention.
