Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a tension-reducing adhesive patch. Background Technology

[0002] Tension-reducing dressings are important medical devices used in wound healing. Their main purpose is to counteract the tension of mature skin, thereby preventing problems such as widening, unevenness, permanent depression, and hyperplasia that can occur during the healing of tension-related wounds. This is because a large amount of tender tissue grows during wound healing, and this tender tissue is not covered by skin. Meanwhile, the mature skin on both sides of the wound has significant tension. This tension can widen the wound, leading to the aforementioned problems such as unevenness, permanent depression, and hyperplasia. To avoid these problems, tension-reducing dressings are applied to the skin on both sides of the wound.

[0003] Existing tension-reducing patches only have one patch on each side of the wound. During follow-up examinations, the traction straps connecting the patches need to be loosened or the patches need to be removed directly. Both of these methods release the skin tension at the wound site, which can affect wound healing. In addition, because ordinary patches are quite sticky, removing the patches directly may cause secondary strain on the wound. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a method to reduce adhesive application. This utility model adopts the following technical solution:

[0005] This utility model provides a method for reducing adhesive tape, including:

[0006] The distal patch consists of two distal patches arranged on both sides of the wound. A reinforcing base band is provided on the side of the distal patch closest to the wound. The reinforcing base band is arranged along the length of the distal patch, and the ends of the reinforcing base bands on both sides are connected by a tension structure.

[0007] The near zone patch consists of two patches, each positioned on one side of the wound. The near zone patch is located inside the far zone patch. The near zone patch includes a backing layer, with a gel layer on one side and several barbs on the other side. The barbs on both sides of the backing layer are connected by a loop pull cord.

[0008] Preferably, the traction structure includes two pawls and two racks. The two pawls are respectively fixed to the reinforcing base bands on both sides of the wound, and each of the two pawls is provided with ratchet teeth. The tail of the rack is fixed to the reinforcing base band on one side, and the head of the rack engages with the ratchet teeth on the pawl on the opposite side.

[0009] Preferably, the outer end of the pawl curves upward.

[0010] Preferably, the head of the rack is provided with anti-slip texture.

[0011] Preferably, the gel layer has a release paper on the side opposite to the backing layer.

[0012] Preferably, both the near-field patch and the far-field patch are provided with a plurality of vent holes.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] The present invention provides a distal patch that significantly reduces tension at a distance from the wound, and a proximal patch that gently adheres to the wound to reduce tension. The combination of the distal and proximal patches protects the wound. Attached Figure Description

[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.

[0021] like Figure 1 and 2 As shown, this embodiment discloses a tension-reducing patch, including a distal patch 1 and a proximal patch 4, with the distal patch 1 being farther away from the wound 7 than the proximal patch 4. The distal patch 1 provides strong tension reduction at a greater distance from the wound 7, while the proximal patch 4 provides light tension reduction near the wound 7. The combination of the distal patch 1 and the proximal patch 4 protects the wound 7.

[0022] Two distal patches 1 are placed on either side of the wound 7. A reinforcing base band 2 is located on the side of the distal patch 1 closest to the wound. The reinforcing base band 2 has sufficient strength and is not easily bent. The reinforcing base band 2 is arranged along the length of the distal patch 1, and the ends of the two reinforcing base bands 2 are connected by a traction structure 3. The traction structures 3 at both ends simultaneously pull the two reinforcing base bands 2, causing the skin covered by the distal patch 1 to converge towards the wound 7. The reinforcing base band 2 and the traction structure 3 can be made of materials such as nylon, polyethylene, polypropylene, or polyvinyl chloride. The distal patch 1 is generally a non-woven fabric patch.

[0023] There are two near-zone patches 4, which are respectively arranged on both sides of the wound 7. The near-zone patches 4 are located inside the far-zone patches 1. The near-zone patches 4 include a backing layer 401. A gel layer 402 is provided on one side of the backing layer 401, and several barbs 403 are provided on the other side. The barbs 403 on the two backing layers 401 are connected by a ring pull cord 5.

[0024] The working principle of this utility model is as follows: the distal patch 1 exerts strong tension reduction at a distance from the wound 7, while the proximal patch 4 gently adheres and reduces tension near the wound 7. During wound re-examination, the distal patch 1 and the traction structure 3 remain fixed, and only the proximal patch 4 is manipulated. This avoids the complete release of skin tension at the wound 7. Simultaneously, when manipulating the proximal patch 4, one step is to loosen the ring-shaped pull cord 5, and the other is to completely remove the proximal patch 4. After the wound re-examination is completed, a new proximal patch 4 is applied. Because the proximal patch 4 is made of gel material, its adhesive strength is less than that of ordinary non-woven fabric patches. Therefore, even if the proximal patch 4 is replaced, it will not damage the wound 7. A release paper is provided on the side of the gel layer 402 opposite to the backing layer 401. When the proximal patch 4 is not in use, the release paper covers the gel layer 402.

[0025] like Figure 3 As shown, in this embodiment, the traction structure 3 includes two pawls 301 and two racks 302. The two pawls 301 are respectively fixed to the reinforcing base bands 2 on both sides of the wound, and each pawl 301 is provided with ratchet teeth 303. The tail of the rack 302 is fixed to one side of the reinforcing base band 2, and the head of the rack 302 engages with the ratchet teeth 303 on the opposite pawl 301. The pawl 301 is provided with a through hole for the rack 302 to pass through. After the rack 302 passes through the through hole on the pawl 301, it engages with the ratchet teeth 303.

[0026] In this embodiment, the outer end of the pawl 301 is raised upwards. If too much force is applied, causing the rack 302 to be stretched too much, the pawl 301 can cause the ratchet 303 to release the rack 302, thereby flexibly adjusting the degree of closure of the traction structure 3.

[0027] In this embodiment, the head of the rack 302 is provided with anti-slip texture, which makes it easy to pull the rack 302.

[0028] In this embodiment, both the near-area patch 4 and the far-area patch 1 are provided with a number of ventilation holes 6, which provide good ventilation for the human skin at the patch coverage area.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
