Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical technology, and in particular to an adjustable-size CVC dressing protection device for children's legs. Background Technology
[0002] CVC dressings are medical dressings used to protect the position of central venous catheters. They are commonly used in patients undergoing long-term intravenous therapy, infusions, and nutritional support. A CVC is a catheter inserted deep into a blood vessel through the skin, often used for patients requiring long-term infusions or blood draws. The main function of a CVC dressing is to protect the CVC site, preventing bacteria or external contaminants from entering the insertion site, reducing the risk of infection, and maintaining catheter stability. This includes ensuring CVC stability, preventing catheter displacement or slippage, protecting the skin in the insertion area, reducing discomfort caused by friction or improper fixation, and providing moisture and protection to the wound at the CVC insertion site, promoting wound healing.
[0003] However, in existing technologies, pediatric central venous catheters are generally placed in the femoral vein, which is located in the groin, close to the vulva and urethra. This makes it easy for children to come into contact with the insertion site of the CVC when urinating. If not properly managed or protected, urine and other bodily fluids may contaminate the catheter and its surrounding area, causing infection, which is a defect. Utility Model Content
[0004] The purpose of this invention is to address the technical problem in existing solutions where pediatric central venous catheters are typically placed in the femoral vein, which is located at the root of the thigh, close to the vulva and urethra. This makes it easy for children to come into contact with the insertion site of the CVC when urinating. If not properly managed or protected, this could lead to contamination of the catheter and its surrounding area by urine and other bodily fluids, causing infection. Therefore, this invention proposes an adjustable-size pediatric leg CVC dressing and protection device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable-size CVC dressing protection device for children's legs, including a waterproof ring, a support frame fitted at one end of the waterproof ring, a pad fixedly connected inside the support frame, the outer surface of the pad located inside the waterproof ring, two first mounting holes opened at both ends of the pad, four second mounting holes opened on the outer surface of the support frame, two first mounting holes forming a group, adjusting members embedded in the inner wall surfaces of the two groups of first mounting holes, and the outer surfaces of the two adjusting members near their ends embedded inside the four second mounting holes.
[0006] Furthermore, springs are fixedly connected to one side surface of each of the two adjusting members, and one end of each spring is fixedly connected to the inner wall surface of the support frame.
[0007] Furthermore, pressure plates are fixedly connected to both ends of the two adjusting members, and the two pressure plates are arranged opposite to each other.
[0008] Furthermore, the outer surfaces of both pressure plates are provided with multiple grooves, which are equidistantly distributed.
[0009] Furthermore, a viewing window is provided on the outer surface of the waterproof ring, and a transparent protective film is embedded inside the viewing window.
[0010] Furthermore, a rubber pad is fixedly connected to one side surface of each of the two adjusting components, and one side surface of the two rubber pads is attached to the outer surface of the waterproof ring.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, during use, the pediatric CVC dressing is placed at the femoral vein. The waterproof ring is placed on the patient's leg and moved to the CVC dressing location. The two ends of the two adjusting members are pressed, and the two adjusting members slide inside the two first mounting holes and two second mounting holes respectively, squeezing the two springs. The two springs compress their stroke, absorbing kinetic energy, and causing the two adjusting members to move away from the waterproof ring. Then, one end of the waterproof ring is pulled, and the support frame is pushed towards the patient's leg, compressing the diameter of the waterproof ring so that the inner wall surface of the waterproof ring wraps the CVC dressing and adheres to the outer surface of the patient's leg. Then, the two adjusting members are released, and the two springs push the two adjusting members to reset. The two adjusting members clamp and fix the outer surface of the waterproof ring through the pad, which can prevent the CVC dressing from getting wet when the patient urinates, thus avoiding contamination of the CVC dressing and effectively preventing bacteria from entering the body through the moist dressing, reducing the risk of infection.
[0013] 2. In this utility model, pressing two pressure plates and two adjusting parts facilitates the application of force. Multiple equidistantly distributed grooves evenly increase friction, preventing hand slippage and ensuring stability during operation. The transparent protective film inside the viewing window provides a direct view of the placement of the central venous catheter, allowing for timely feedback in case of problems. Two rubber pads prevent friction between the outer surface of the waterproof ring and the adjusting parts, preventing wear of components due to friction between the waterproof ring and the adjusting parts when adjusting the diameter of the waterproof ring, thus ensuring the service life and strength of the components.

[0019] 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.
[0020] Example 1
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: an adjustable-size CVC dressing protection device for children's legs, including a waterproof ring 1, a support frame 2 fitted at one end of the waterproof ring 1, a pad 3 fixedly connected inside the support frame 2, the outer surface of the pad 3 located inside the waterproof ring 1, two first mounting holes 11 opened at both ends of the pad 3, four second mounting holes 12 opened on the outer surface of the support frame 2, two first mounting holes 11 forming a group, an adjusting member 4 embedded in the inner wall surface of both groups of first mounting holes 11, the outer surfaces of the two adjusting members 4 near both ends embedded inside the four second mounting holes 12, a spring 7 fixedly connected to one side surface of the two adjusting members 4, and one end of the two springs 7 fixedly connected to the inner wall surface of the support frame 2.
[0022] In this embodiment, during use, the pediatric CVC dressing is placed at the femoral vein. The waterproof ring 1 is placed on the patient's leg and moved to the CVC dressing location. The two ends of the two adjusting members 4 are pressed, and the two adjusting members 4 slide inside the two first mounting holes 11 and the two second mounting holes 12 respectively, squeezing the two springs 7. The two springs 7 compress their stroke, absorbing kinetic energy, and causing the two adjusting members 4 to move away from the waterproof ring 1. Then, one end of the waterproof ring 1 is pulled, and the support frame 2 is pushed towards the patient's leg, compressing the diameter of the waterproof ring 1 so that the inner wall surface of the waterproof ring 1 wraps the CVC dressing and adheres to the outer surface of the patient's leg. Then, the two adjusting members 4 are released, and the two springs 7 push the two adjusting members 4 back to their original position. The two adjusting members 4 are clamped and fixed to the outer surface of the waterproof ring 1 by the pad 3, which can prevent the CVC dressing from getting wet when the patient urinates, thus avoiding contamination of the CVC dressing and effectively preventing bacteria from entering the body through the moist dressing, reducing the risk of infection.
[0023] Example 2
[0024] like Figure 1-4 As shown, pressure plates 5 are fixedly connected to both ends of the two adjusting parts 4. The two pressure plates 5 are arranged opposite each other. Multiple grooves 10 are opened on the outer surface of the two pressure plates 5. The multiple grooves 10 are evenly distributed. A viewing window 8 is opened on the outer surface of the waterproof ring 1. A transparent protective film 9 is embedded inside the viewing window 8. Rubber pads 6 are fixedly connected to one side surface of the two adjusting parts 4. One side surface of the two rubber pads 6 is attached to the outer surface of the waterproof ring 1.
[0025] In this embodiment, pressing the two pressure plates 5 and the two adjusting parts 4 facilitates the application of force. Multiple equally spaced grooves 10 uniformly increase friction, preventing slippage and ensuring stability during operation. The transparent protective film 9 inside the viewing window 8 provides a direct view of the placement of the central venous catheter, allowing for timely feedback in case of problems. The two rubber pads 6 prevent friction between the outer surface of the waterproof ring 1 and the adjusting parts 4, thus preventing wear of components due to friction between the waterproof ring 1 and the adjusting parts 4 when adjusting the diameter of the waterproof ring 1, ensuring the service life and strength of the components.
[0026] Working principle: such as Figure 1-4As shown, during use, the pediatric CVC dressing is placed on the femoral vein. The waterproof ring 1 is placed on the patient's leg and moved to the CVC dressing area. By pressing the two pressure plates 5, the two adjusting pieces 4 are pressed. The two adjusting pieces 4 slide inside the two first mounting holes 11 and the two second mounting holes 12 respectively, squeezing the two springs 7. The two springs 7 compress their stroke, absorbing kinetic energy, and causing the two adjusting pieces 4 to move away from the waterproof ring 1. Then, one end of the waterproof ring 1 is pulled, and the support frame 2 is pushed towards the patient's leg, compressing the diameter of the waterproof ring 1 so that the inner wall surface of the waterproof ring 1 wraps around the CVC dressing and conforms to the patient's leg. The outer surface of the device is fitted together, and then the two adjusting parts 4 are released. The two springs 7 push the two adjusting parts 4 to reset. The two adjusting parts 4 clamp and fix the outer surface of the waterproof ring 1 through the pad 3. Multiple equally spaced grooves 10 evenly increase the friction force to prevent slippage and ensure stability during operation. The placement of the central venous catheter can be seen intuitively through the transparent protective film 9 inside the viewing window 8. Problems can be reported in time. The two rubber pads 6 prevent the outer surface of the waterproof ring 1 from rubbing against the adjusting parts 4, and prevent the waterproof ring 1 from rubbing against the adjusting parts 4 when adjusting the diameter of the waterproof ring 1, which would cause wear of the parts.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
