[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] like Figures 2 to 9 The nail channel protection composite sticker of the external fixation bracket 02 shown includes an inner sticker 1 and an outer sticker 2, both of which are made of flexible materials, wherein:

[0037] like Figure 2 and Figure 3 As shown in, the inner patch 1 includes a main body 11 and a water-absorbing pad 12 fixed at the bottom of the main body 11, the inner patch 1 is provided with a nail channel hole 13 and a notch 14 extending from the nail channel hole 13 to the edge of the inner patch 1, and the bottom of the main body 11 is provided with an adhesive layer; it should be pointed out here that in the embodiment of the utility model, the inner patch 1 is similar to a band-aid, the main body 11 is a non-woven fabric base tape or a polyethylene film base tape, the adhesive layer is fixed on the main body 11, and the water-absorbing pad 12 is fixed on the adhesive layer; in the embodiment of the utility model, the nail channel hole 13 and the notch 14 penetrate the inner patch 1 in the thickness direction, that is, the nail channel hole 13 and the notch 14 are provided on both the main body 11 and the water-absorbing pad 12, and by such a configuration, the notch 14 can be opened when the patient is provided with nail channel protection so that the screw 01 can enter the nail channel hole 13 along the notch 14, thereby wrapping the skin around the nail channel;

[0038] Please continue to refer to Figure 2 and Figure 3In the embodiment of the utility model, the outer patch 2 includes a first base 21 for covering the body 11 and a second base 22 arranged on the first base 21. Two second bases 22 are arranged opposite to each other. The first base 21 has a channel for the screw 01 to penetrate into the middle of the two second bases 22. The first base 21 covers the inner patch 1 and is bonded to the skin surface where the patient's nail channel is located. The two second bases 22 are bonded to each other and cover the circumferential surface of the screw 01 protruding from the skin surface at a set height. It should be pointed out here that in the embodiment of the utility model, the inventive concept is to cover the inner patch 1 with the first base 21, and to wrap the screw 01 above the nail channel hole 13 with the second base 22. By such a setting, the gap between the nail channel hole 13 and the screw 01 is sealed, avoiding the wound from being infected due to contact with the outside world.

[0039] like Figure 4 As shown in the figure, when the nail channel protection sticker of the external fixation bracket 02 in the embodiment of the utility model is specifically pasted, first, the inner sticker 1 is covered on the skin around the screw 01 as in the above steps, and then the two second bases 22 of the outer sticker 2 are brought close to each other, and the two second bases 22 are respectively located on both sides of the screw 01, and then the two second bases 22 are attached to each other to cover the part of the screw 01 exposed outside the skin, and then the first base 21 is covered on the upper part of the inner sticker 1, as shown in the figure. Figure 4 As shown in the above arrangement, since the periphery of the inner patch 1 is covered by the first substrate 21, the first substrate 21 forms a seal in contact with the skin, and the outside air cannot enter the nail channel along the skin surface. In addition, the second substrate 22 covers the screw 01. Since the second substrate 22 is connected to the first substrate 21, the path for the outside air to enter the nail channel is isolated, thereby reducing the possibility of infection of the wound at the nail channel.

[0040] In the above embodiment, by attaching the outer patch 2 to the inner patch 1, the first substrate 21 on the outer patch 2 covers the inner patch 1, and the second substrate 22 covers the screw 01, thereby blocking the path of outside air entering the nail channel. Compared with the prior art, the wound at the nail channel hole 13 is isolated from the outside world, reducing the possibility of wound infection.

[0041] On the basis of the above embodiments, in the embodiments of the present utility model, the external sticker 2 has a variety of structural forms, which can be split or integrated, such as Figure 2 and Figure 3As shown in the embodiment of the utility model, the outer patch 2 is a split type, and the two second substrates 22 are respectively arranged at one end of the two first substrates 21. Of course, it should be pointed out here that since the second substrate 22 and the first substrate 21 are both flexible, the first substrate 21 and the second substrate 22 can be arranged on the same plane in the initial state, and operated by the nursing staff, that is, at this time, the part attached to the skin covering the inner patch 1 is the first substrate 21, and the parts of the two opposing patches covering the screws 01 are the second substrates 22.

[0042] In other embodiments of the present invention, the external patch 2 is an integrated arrangement, and the two second substrates 22 are symmetrically arranged in the middle of the first substrate 21, and the first substrate 21 has a connecting portion 23 between the two second substrates 22. Through the integrated design, the root of the second substrate 22 is fixed in the middle position, which is convenient for taking out and operating the composite patch. Of course, it should be pointed out here that the connecting portion 23 has a variety of structural forms, which can be as follows: Figure 5 As shown in the figure, the connection part 23 is arranged on one side of the two second substrates 22, and the width of the two second substrates 22 is not less than two-thirds of the width of the first substrate 21. It should be pointed out here that in the embodiment of the present utility model, the material of the connection part 23 is the same as that of the first substrate 21. Figure 6 As shown in , the connecting portion 23 is first pinched together, and then the channel between the two second substrates 22 is passed through the screw 01, and finally the two second substrates 22 are fitted and connected; in addition, it should be pointed out here that in order to further improve the sealing performance, as Figures 2 to 4 As shown in FIG. 1 , when the channel formed at the root of the two second substrates 22 is bonded to the inner sticker 1 , the direction of the channel after bonding is offset from the direction of the notch 14 on the inner sticker 1 to avoid a gap between the notch 14 and the channel.

[0043] In some embodiments of the present invention, Figure 7 and Figure 8 As shown in , the connection part 23 is improved. The connection part 23 is an easy-tear structure arranged on the first substrate 21 along the width direction of the first substrate 21, and the two second substrates 22 are arranged on both sides of the easy-tear structure. It should be pointed out here that the easy-tear part is an easy-tear structure formed by serrations or indentations or holes arranged in an array. Through the arrangement of this structural form, the applicability of the external patch 2 can be improved. When the external patch 2 is attached, it can be torn off according to the set distance as needed, and the other part remains connected, which is conducive to improving the convenience of operation.

[0044] In some embodiments of the utility model, in order to facilitate the storage and attachment of the external patch 2, a fold is provided at the connection between the second substrate 22 and the first substrate 21. The fold is provided to facilitate the neat attachment of the roots of the two second substrates 22, and to reduce the occupied area during packaging, which is beneficial to improving the reliability of the product.

[0045] Of course, it should be pointed out here that in the embodiment of the utility model, the specific shapes of the inner sticker 1 and the outer sticker 2 are not limited, and they can be set according to the position of the screw 01 and the size of the screw 01. In some embodiments of the utility model, the inner sticker 1 and the first substrate 21 are polygonal, circular, elliptical, fan-shaped or oblong structures. It should be pointed out here that the oblong structure is as follows: Fig. 9 As shown in FIG, the first substrate 21 has arc shapes at both ends and a rectangular structure in the middle.

[0046] Please continue to refer to Figure 4 , since the parts of the two second substrates 22 wrapped around the outside of the screw 01 after being attached are redundant, in order to reduce the impact of this part on the human body, in the embodiment of the utility model, the width of the second substrate 22 at the end away from the first substrate 21 is smaller than the width close to the first substrate 21. In addition, when wrapping the screw 01, it is also possible to use a second substrate 22 to wrap around the screw 01 first, and then use another second substrate 22 to wrap around the screw 01 to reduce the space occupied by the second substrate 22 outside the screw 01. In some embodiments of the utility model, please continue to refer to Fig. 9 The second base 22 is triangular or trapezoidal. This arrangement can not only wrap the screw 01, but also reduce the space occupied by the redundant part.

[0047] In addition, in some embodiments of the present invention, the bottom of the first substrate 21 and the surface of the second substrate 22 facing each other are both provided with an adhesive layer. In order to facilitate operation and reduce accidental touch, the adhesive layer is also provided with a release paper (not shown in the figure). When performing the specific bonding operation, the release paper is first torn off and then pasted. For example, when pasting the second substrate 22, the release paper at the root can also be torn off first, and then the rest of the release paper can be torn off while pasting the second substrate 22. In addition, it should be pointed out here that in some embodiments of the present invention, a medical industrial film layer can also be provided on the outer surface of the inner patch 1 to achieve the convenience of replacing the outer patch 2.

[0048] In some embodiments of the present invention, the structure of the water-absorbing pad 12 is also improved, such as Fig.10As shown in the figure, the upper surface of the water absorbent pad 12 is an arc-shaped raised structure. Through this structural improvement, the problem of gaps in the raised edge of the water absorbent pad 12 can be solved. At the same time, the raised structure of the surface of the water absorbent pad 12 increases the thickness of the water absorbent pad 12 and increases the amount of liquid absorbed.

[0049] Please refer to Fig.11 In the embodiment of the utility model, in order to further avoid the secondary processing of the second substrate 22 on both sides of the ingot, as Fig.11 As shown in the figure, the second base 22 has an easy-tear seam 22a arranged parallel to the fold near the fold, and the easy-tear seam 22a is disconnected at the corresponding position of the nail channel hole 13. The position corresponding to the nail channel hole 13 here refers to the width position of the screw 01 wrapped at least half a circle. Through the setting of the easy-tear seam 22a, the easy-tear seam 22a can be torn off after the screw 01 is covered on one side, and the parts on both sides of the screw 01 are wrapped and pasted on the screw 01 to avoid space occupation on both wings. Of course, it should be pointed out here that in the embodiment of the utility model, it can also be achieved by directly cutting without the easy-tear seam 22a, and the above methods all fall within the protection scope of the utility model.

[0050] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
