Description

Technical Field

[0001] This utility model relates to the field of dressing patch technology, and in particular to an anti-adhesion antibacterial hydrocolloid dressing patch. Background Technology

[0002] In the field of wound care, dressings are key medical products for protecting wounds and promoting healing. They are widely used in everyday abrasions, postoperative wounds, chronic ulcers, and other scenarios. Their core requirements are not only to isolate external bacteria and keep the wound moist, but also to adapt to the care needs of wounds in different locations. Appropriate external force is needed to keep the two ends of the wound close together to reduce wound tension and accelerate tissue regeneration and healing. With the upgrading of nursing concepts, dressings that combine anti-adhesion, antibacterial, and healing-aiding functions have become an important direction for improving the quality of wound care.

[0003] Existing wound dressing patches use breathable non-woven fabric or film as the base material and are fixed to the skin around the wound by adhesive edges. They can only achieve wound isolation and basic moisturization. Some wound dressing patches integrate hydrocolloid layers, antibacterial ingredients, etc. The hydrocolloid layer can absorb wound exudate to form a gel and maintain a moist healing environment, while the antibacterial ingredients are used to inhibit bacterial growth.

[0004] However, existing wound dressings are not effective at closing the wound. Traditional adhesive dressings rely solely on edge adhesion for simple fixation, which cannot provide a continuous and stable force to close the wound ends. Especially in active areas such as joints, the wound is prone to separation due to skin traction, thus prolonging the healing time. Utility Model Content

[0005] Given that existing wound dressings are insufficient in their ability to close up wounds, and that traditional adhesive dressings rely solely on edge adhesion for simple fixation, they cannot provide a continuous and stable force to close up both ends of the wound. Especially in active areas such as joints, the wound is prone to separation due to skin traction, thus prolonging the healing time. Therefore, this utility model was proposed.

[0006] Therefore, the purpose of this invention is to fix both ends of the wound with adhesive strips and, together with the toothed fixation patch and unidirectional locking fixation strap, provide a continuous and stable closing force for the wound, reduce wound tension, prevent wound separation due to movement, and accelerate the healing process. It is especially suitable for joints and other easily stretched areas. The hydrocolloid layer can absorb exudate to form a gel, maintaining a moist environment on the wound surface. The breathable dressing patch ensures that the wound is breathable while forming a sealed protection with the fixation patch to isolate external pollution.

[0007] To solve the above technical problems, the present invention provides the following technical solution: an anti-adhesion antibacterial hydrocolloid dressing patch, comprising a fixing patch and a fixing connecting piece on one side of the fixing patch, wherein a breathable dressing patch is provided on one side of the fixing connecting piece; The limiting component includes two limiting connecting blocks installed on one side of the fixed patch, and two limiting connecting grooves are opened on the inner side of each limiting connecting block; The restraint assembly includes two adhesive strips mounted on one side of the fixing patch, and each adhesive strip has two fixing straps on one side.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides an anti-adhesion antibacterial hydrocolloid dressing patch, including a fixing patch 1 and a fixing connecting piece 2 on one side of the fixing patch 1. A breathable dressing patch 3 is provided on one side of the fixing connecting piece 2, including two limiting connecting blocks 8 installed on one side of the fixing patch 1. Two limiting connecting grooves 9 are opened inside each limiting connecting block 8. A dressing hole 6 is opened on the fixing patch 1. A hydrocolloid layer 4 is provided on one side of the breathable dressing patch 3, and one end of the hydrocolloid layer 4 is located inside the dressing hole 6. An auxiliary patch 7 is provided on one side of the fixing patch 1. One end of the auxiliary patch 7 is attached to the fixing connecting piece 2. One end of each fixing strap 12 is inserted into the inner side of the corresponding limiting connecting groove 9. Multiple fixing holes 10 are opened on the fixing patch 1. One end of each fixing strap 12 passes through the corresponding fixing hole 10 and is placed between the fixing patch 1 and the breathable dressing patch 3.

[0024] Example 2 Reference Figure 3-6 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that it includes two adhesive strips 11 installed on one side of the fixing patch 1. Each adhesive strip 11 has two fixing straps 12 on one side. The breathable dressing patch 3 has multiple insertion and fixing slots 5. One end of some fixing straps 12 is located inside the corresponding insertion and fixing slot 5. Each fixing strap 12 has a toothed fixing piece 13 on one side, and one side of each toothed fixing piece 13 is attached to the inner wall of the corresponding limiting connection groove 9. The fixing patch 1 has an anti-adhesion patch 14 on one side, and one end of each adhesive strip 11 is located inside the anti-adhesion patch 14.

[0025] When using, the anti-adhesion patch 14 covers the surface of the adhesive strip 11 on one side of the fixing patch 1 to prevent the adhesive strip 11 from sticking to dust or sticking itself in advance. First, peel off the anti-adhesion patch 14 to expose the adhesive side of the adhesive strip 11. Then, align the fixing patch 1 with the wound position so that the wound is accurately centered at the dressing hole 6 on the fixing patch 1. Press the fixing patch 1 and the adhesive strips 11 on both sides to make the adhesive strips 11 adhere tightly to the skin at both ends of the wound.

[0026] Two adhesive strips 11 correspond to the two sides of the wound respectively, providing a fixed base for subsequent wound closure. At the same time, the fixation patch 1 is initially fixed to the skin surface by the adhesive of its own edge, ensuring that the overall position does not shift and the pulling force is transmitted to the wound. After the adhesive strips 11 are fixed, the fixation strap 12 on one side is pulled. One end of the fixation strap 12 passes through the fixation hole 10 on the fixation patch 1 and is located between the fixation patch 1 and the breathable dressing patch 3. The other end is inserted into the limiting connecting groove 9 of the limiting connecting block 8, and the toothed fixing piece 13 on one side of the fixation strap 12 is attached to the inner wall of the limiting connecting groove 9.

[0027] When the fixing band 12 is pulled, the adhesive strip 11 will pull the skin at both ends of the wound toward the center, reducing wound tension. When the two ends of the wound are pulled to a suitable distance, the fixing band 12 is stopped. The toothed structure of the toothed fixing piece 13 will be locked at the protrusion on the inner wall of the limiting connecting groove 9, preventing the fixing band 12 from retracting. This provides a continuous and stable force to bring the two ends of the wound together, avoiding wound separation due to natural skin tension or human activity.

[0028] In the initial state, the auxiliary patch 7 on one side of the fixation patch 1 is attached to the breathable dressing patch 3 to prevent the breathable dressing patch 3 from sticking to the fixation patch 1 in advance when not in use, which would affect subsequent operations. At the same time, it forms a sealed protection for the hydrocolloid layer 4 on one side of the breathable dressing patch 3, reducing the loss of moisture from the hydrocolloid layer 4 and maintaining its moisturizing performance. After the wound is closed, the auxiliary patch 7 is removed.

[0029] At this point, the breathable dressing patch 3 is no longer constrained by the auxiliary patch 7 and can be attached towards the fixed patch 1. Since the thickness of the hydrocolloid layer 4 is greater than that of the fixed patch 1 and one end is aligned with the dressing hole 6, when the breathable dressing patch 3 is pressed, the hydrocolloid layer 4 will pass through the dressing hole 6 and come into direct contact with the wound surface. The hydrocolloid layer 4 can absorb the exudate from the wound surface and form a gel-like substance, which can maintain a moist healing environment for the wound surface and inhibit bacterial growth through its own antibacterial components, thereby reducing the risk of infection.

[0030] The breathable dressing patch 3 fits tightly to the fixation patch 1, forming an overall seal with the fixation patch 1 through the adhesiveness of its own edges, isolating external dust and bacteria from contacting the wound. The insertion and fixing groove 5 on the breathable dressing patch 3 cooperates with one end of part of the fixation strap 12, further restricting the position of the fixation strap 12, preventing it from shifting during use, and enhancing the wound closing effect.

[0031] The remaining structure is the same as that in Example 1.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
