Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dressing change kit for infants and young children with long-term leakage at the deep vein catheterization site. Background Technology

[0002] Central venous catheterization refers to a treatment method in which a catheter is inserted into a deep large vein or central vein through a relatively superficial vein. Central venous catheterization is frequently used in various emergency situations, major surgeries, especially cardiac surgeries that require long-term monitoring of medication, blood draws, and laboratory tests; and in situations involving continuous hemodialysis, long-term blood transfusions, intravenous infusions, and long-term medication.

[0003] Central venous catheterization is essential for ensuring critically ill patients receive the necessary blood gas and electrolyte tests, monitor central venous pressure, and administer medications safely and effectively. It plays a crucial role in the resuscitation, treatment, and monitoring of critically ill patients, significantly improving the success rate of resuscitation efforts.

[0004] Currently in clinical practice, young children with severe edema require nutritional management and hemodialysis. After the insertion of a central venous catheter, some catheters that cannot be cut are exposed, and there is also a lot of leakage. This leads to problems such as frequent dressing changes at the catheter insertion site, repeated skin tearing and damage, and the inability to fix the exposed catheter due to its excessive length. The dressing change kits currently available in clinical practice cannot solve this problem. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dressing change kit for infants and young children with long-term leakage at the deep vein catheter insertion site. It aims to improve the problems in the existing technology where, after a child has a deep vein catheter inserted, some catheters that cannot be cut are exposed, resulting in a lot of leakage, frequent dressing changes at the insertion site, repeated skin tearing and damage, and excessively long exposed catheters that cannot be fixed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dressing change kit for infants and young children with persistent oozing from deep vein catheterization sites includes a dressing bag, an inner wall of which is equipped with a sterilization pack, a skin protective dressing, an exposed catheter dressing, and a sterile gauze cover. Elastic strips are fixedly connected to both the front and back sides of the sterile gauze cover. The inner wall of the dressing bag also includes a hemostatic component for the puncture site where there is continuous bleeding. As a further description of the above technical solution: The hemostatic assembly includes a stretchable adhesive tape, the outer surface of which is placed on the inner wall of the dressing bag. A pressable circular plate is fixedly connected to the bottom of the stretchable adhesive tape, an oil-based antibiotic is fixedly connected to the bottom of the pressable circular plate, and a highly absorbable dressing is fixedly connected to the bottom of the oil-based antibiotic. As a further description of the above technical solution: The exposed catheter dressing is made of polyurethane, and the sterile gauze cover is made of sterile cotton. As a further description of the above technical solution: The oil-based antibiotic is composed of an oil matrix and an antibiotic, and the pressable disc is made of polycarbonate plastic. As a further description of the above technical solution: A dialysis catheter is fixedly connected to the left side of the sterile gauze cover. The dialysis catheter is made of polyvinyl chloride. As a further description of the above technical solution: The elastic adhesive tape is made of elastic fabric, and the bottom of the highly absorbent dressing comes into direct contact with the human body.

[0007] As a further description of the above technical solution: The disinfection pack consists of an alcohol bag or an iodine bag, and the skin protective dressing is made of a natural polymer material. As a further description of the above technical solution: The middle part of the skin protective dressing is fixedly connected to two quick-adhesive patches, and the adjacent sides of the two quick-adhesive patches are adhered to each other.

[0008] This utility model has the following beneficial effects: 1. In this utility model, the operator passes the skin protection dressing through the deep vein catheter and sticks it to the skin around the insertion site to prevent bleeding from damaging the skin and further prevent the catheter fixation dressing from damaging the skin during repeated dressing changes.

[0009] 2. The long strip-shaped catheter fixation film is relatively small in area when fixing catheters that cannot be cut, making it easy to replace and operate, and reducing damage to the skin from repeated tearing.

[0010] 3. A sterile gauze cover is used to fix the interface of the deep vein catheter for dialysis or infusion. Both ends are made of elastic material to facilitate wrapping and fixation, reducing the risk of infection caused by catheter exposure.

[0011] 4. In this invention, the highly absorbent dressing comes into direct contact with the human body, rapidly absorbing blood and exudate. Medical personnel apply pressure to the compression plate, further reducing bleeding. The surface oil contains antibiotics to prevent infection at the puncture site and reduce exudate. It keeps the puncture site dry, promoting wound healing. Furthermore, the dressing is relatively small and can be directly fixed to the skin's protective membrane for easy replacement.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Reference Figure 2 and Figure 3This utility model provides an embodiment of a dressing change kit for infants with long-term seepage at deep vein catheter sites. The kit includes a dressing bag 1, which holds various medications. The inner wall of the dressing bag 1 has a sterilization pack 2 for disinfecting the wound and stabilizing it. The inner wall of the dressing bag 1 also has a circular, hollow, adhesive-backed skin protective dressing 3. The dressing 5 directly protects the catheter and stabilizes it. The inner wall of the dressing bag 1 also has a sterile gauze cover 10, which is the outermost layer protecting the internal structure and ensuring its stability. Elastic strips 11 are fixedly connected to both the front and back sides of the sterile gauze cover 10 to improve patient comfort. Finally, the inner wall of the dressing bag 1 has a hemostatic component for the puncture site where there is continuous bleeding.

[0016] Reference Figure 2 and Figure 4 The hemostatic component includes adhesive tape 6, the outer part of which is placed on the inner wall of the dressing bag 1. The adhesive tape 6 is elastic, and a pressable round plate 7 is fixedly connected to the bottom of the adhesive tape 6. The pressable round plate 7 can be pressed to press against the wound to reduce blood seepage. An oil-based antibiotic 8 is fixedly connected to the bottom of the pressable round plate 7. The oil-based antibiotic 8 can form a protective film on the skin surface to prevent moisture loss and at the same time help the antibiotic to be released slowly, exert antibacterial effect, and prevent infection. A highly absorbent dressing 9 is fixedly connected to the bottom of the oil-based antibiotic 8. The highly absorbent dressing 9 comes into direct contact with the human body and can quickly absorb blood and exudate from the puncture site, keep the local area clean and dry, and form a gel-like substance to prevent blood and exudate leakage and help wound healing.

[0017] Reference Figures 1 to 3The exposed catheter dressing 5 is made of polyurethane, which secures the CVC catheter, preventing displacement, twisting, or dislodgement, ensuring smooth medical procedures such as infusion and blood collection, and guaranteeing the continuity and effectiveness of treatment. The sterile gauze cover 10 is made of sterile cotton, which cushions the patient area, thus stabilizing it. The oil-based antibiotic 8 consists of an oil matrix and antibiotics. The oil matrix forms a uniform and delicate protective film on the skin surface, effectively preventing moisture loss, while the antibiotics provide antibacterial protection to the wound, reducing wound ulceration. The pressable round plate 7 is made of polycarbonate plastic, which has high resilience, making it easy to rebound. The left side of the sterile gauze cover 10 is fixedly connected to the dialysis catheter 12, which is directly fixed to the wound and is the catheter for dialysis. The dialysis catheter 12 is made of polyvinyl chloride, which has the characteristics of low cost and good flexibility. The elastic adhesive tape 6 is made of elastic fabric, which can stretch and contract with body movement and has moderate stickiness. The bottom of the highly absorbent dressing 9 is in direct contact with the human body, and its strong absorption of blood and exudate can reduce blood seepage at the wound site. The disinfection pack 2 consists of an alcohol bag or an iodine bag, both of which are used to disinfect the wound. The skin protective dressing 3 is made of a natural polymer material, which conforms to the human body and thus stabilizes it. The middle part of the skin protective dressing 3 is fixedly connected to two quick-adhesive patches 4. The adjacent sides of the two quick-adhesive patches 4 are adhered to each other. The quick-adhesive patches 4 allow the skin protective dressing 3 to close quickly and fix it to the catheter.

[0018] Working principle: The operator first disinfects the patient's puncture site with a sterilization pack, then removes the previous supplies and applies the exposed catheter dressing to the patient's catheter to reduce external bacterial contamination. The catheter is then passed through the hole in the skin protective dressing. The sterilization pack is then placed on top, and an elastic strip is used to ensure that the sterile gauze cover fits tightly against the puncture site. This allows the catheter to be placed inside the sterile gauze cover, providing a place for the catheter to rest. This achieves fixation of the catheter, which cannot be cut, and also prevents catheter displacement, thereby reducing the risk of increased exudation and infection caused by catheter position changes.

[0019] Medical staff apply a highly absorbable dressing directly to the puncture site, allowing it to absorb any oozing blood. Applying pressure to a compressible plate further reduces bleeding at the puncture site. Combined with the effects of the oil-based antibiotics, this accelerates wound healing, effectively stopping bleeding at the puncture site. Furthermore, it significantly reduces the risk of infection caused by blood oozing, creating a favorable environment for healing at the deep vein replacement site and promoting the patient's recovery. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
