DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present disclosure, the drawings required for use in the embodiments will be briefly introduced below. It should be understood that the following drawings only show certain embodiments of the present disclosure and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without creative work.

[0029] It should be noted that when the present invention is used, the release layer is at the bottom layer and the waterproof layer is at the top layer. Figure 1-5 All are displayed with the release layer facing up.

[0030] At the same time, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description. Therefore, they cannot be understood as limitations on the present disclosure. At the same time, the present application is described based on the inner and outer rings of the fan-shaped ring, with the inner ring close to the center and the outer ring away from the center. At this time, the outer ring and the inner ring are considered to be parallel, that is, the inner ring surface and the outer ring surface are also considered to be parallel to each other in the present disclosure.

[0031] like Figure 1-7 As shown, the present disclosure provides a three-dimensional nail duct patch, including a nail duct patch body 1. The nail duct patch body 1 is a composite layer structure composed of multiple layers of different materials. The upper surface (uppermost layer) of the nail duct patch body 1 is a waterproof layer 11. The material of the waterproof layer 11 is a waterproof PU film. The lower layer of the waterproof layer 11 is a foam absorption layer 12. The foam absorption layer 12 is soft and has high patient comfort. The lower layer of the foam absorption layer 12 is a silicone gel layer 13. The material is porous silicone gel, which is a common type on the market and plays a bonding role. The lower layer of the nail duct patch body 1 is a release layer 14. The release layer 14 adopts release paper. When in use, the release layer 14 is directly torn off, and the uppermost silicone gel layer 13 is adhered to the skin and the metal bone needle. At this time, the nail duct patch body 1 will form a three-dimensional structure, which can fix the metal bone needle and seal the space where the metal bone needle and the skin are connected, reducing the risk of infection.

[0032] In a specific embodiment, the thickness of the foam absorption layer 12 in the nail channel patch body 1 is 2 mm. The foam absorption layer is a soft polyurethane foam material. The nail channel patch body 1 is used in contact with the skin, and the soft material is highly comfortable.

[0033] In another specific embodiment, the nail patch body 1 is constructed in an irregular sector ring shape, including an inner ring surface and an outer ring surface, wherein the inner ring surface is close to the inner ring of the sector ring shape, and the outer ring surface is close to the outer ring of the sector ring shape. Figure 1 As shown, a portion of the nail channel sticker body 1 in the direction from the outer ring to the inner ring is cut off to form an irregular fan-shaped nail channel sticker body 1. The purpose of designing it to be irregular is that when the nail channel sticker body 1 is used, the metal bone needle needs to be wrapped so that the part that fits the skin does not overlap. When the wrapping is completed, the extra part in the direction of the inner ring surface that is cut off can be conveniently adhered to the outer surface of the other end, as shown in the attached figure. Figure 6 shown.

[0034] In another specific embodiment, the bottom release layer 14 of the nail patch body 1 also includes two parts, such as Figure 2 As shown, the left side is the left release paper 141, and the right side is the right release paper 142. The two release papers are overlapped and arranged in an alternating manner. The dotted line represents the boundary of the left release paper 141 covered by the right release paper 142, and the corresponding solid line represents the boundary of the right release paper 142. Figure 3 As shown in FIG. 1 , it is a cross-sectional view of the nail channel sticker body 1 in the AA direction. In the AA cross-sectional view, the left release paper 141 and the right release paper 142 of the release layer 14 are overlapped, so it is a double-layer structure. In the partial cross-sectional view in the BB direction, the right release paper 142 is on top. This design can better protect the inner layer material from being polluted by the external environment. Figure 5 As shown, when in use, first tear off the right release paper 142, and then tear off the left release paper 141, so that the porous silicone gel is partially exposed, and then the skin and the metal bone needle are adhered, which is easy to operate.

[0035] In another specific embodiment, in order to facilitate the use of the three-dimensional nail sticker, the nail sticker body 1 is also provided with two fold lines, such as Figure 3 In the irregular fan ring shown, a first fold line 15 is set at 1 cm from the inner ring of the irregular fan ring, and a second fold line 16 is set at 1 cm from the outer ring of the irregular fan ring. Figure 6 In the three-dimensional structure, the first crease line 15 and the second crease line 16 are the creases for wrapping the bone needle and fitting the skin respectively, and the composite layer structure between the first crease line 15 and the second crease line 16 is not filled with porous silicone gel, corresponding to Figure 3 The composite layer structure between the first crease line 15 and the second crease line 16 in the irregular fan ring is a foam absorption layer when exposed, which will not stick to the metal bone needles, avoiding mis-sticking and affecting the overall adhesive sealing effect.

[0036] In another preferred embodiment, the main adhesive parts of the three-dimensional nail road sticker are the first adhesive part 17 and the second adhesive part 18, see the attached Figure 2 and attached Figure 6 The first adhesive part 17 is a composite layer structure between the first fold line 15 and the inner ring surface as described above, and the second adhesive part 18 is a composite layer structure between the second fold line 16 and the outer ring surface, and for the convenience of use and better fitting, the first adhesive part 17 and the second adhesive part are machine-cut into patches during preparation. When using the three-dimensional nail channel patch of this embodiment, after tearing off the right release paper 142 and the left release paper 141, the four patches of the first adhesive part 17 surround and adhere to the metal bone needle, and the patch will form a through hole, and the metal bone needle passes through the middle. This part completely wraps and adheres the metal bone needle, which can prevent the metal bone needle and bacteria near the through hole from invading. The six patches of the second adhesive part 18 adhere to the skin to form a fitted plane. After the adhesion is completed, the nail channel patch body is a three-dimensional structure, which closes the small space where the skin contacts the bone needle, better fixes the metal bone needle, and greatly reduces the risk of infection at the nail hole.

[0037] One way to use the present disclosure is:

[0038] After the patient completes the orthopedic surgery, the fracture is fixed by external fixation. The metal bone needle is placed into the bone shaft for connection. The metal bone needle is exposed outside the skin. At this time, the three-dimensional nail patch disclosed in the present invention is used to wrap and fix the bone needle. Figure 5 As shown in the figure, the right release paper 142 and the left release paper 141 of the release layer 14 are torn off in turn to expose the silicone gel layer, and the left and right ends of the nail channel patch body 1 are glued together around the metal bone needle. The extra part will be glued to the outer surface of the other end, and the patch of the first adhesive part 17 is glued to the metal bone needle, and the patch of the second adhesive part 18 is glued to the skin. The state after the gluing is completed is as shown in the attached figure. Figure 7 As shown, while fixing the metal bone needle, the small space where the metal bone needle contacts the skin is sealed, which greatly reduces the risk of infection for the patient. In addition, the adhesive part has strong adhesion but is easy to tear off, which is convenient for changing dressings and observing the condition of the patient's affected area.

[0039] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work. Therefore, any technical solution that can be obtained by a technician in the technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
