Description

Technical Field

[0001] This utility model relates to medical supplies, and more specifically to a wound fixation device. Background Technology

[0002] Currently, when people accidentally fall or cut themselves on sharp objects, small wounds can be directly covered with adhesive bandages (sterilized adhesive tape). Longer wounds generally require sutures to promote healing and prevent infection. However, suturing requires a visit to a medical facility by a doctor, and the sutures must be removed after a period of time. This not only necessitates multiple trips to the medical facility but also increases pain during suturing and suture removal. Furthermore, suturing takes a considerable amount of time and presents numerous challenges.

[0003] Therefore, some manufacturers have developed a wound fixation device, as disclosed in US Patent Publication No. US2016 / 0220252A1. This device mainly includes a first patch, a second patch, and a tensioning member. The first patch is adhered to one side of the wound and has a first fixing seat. The second patch is adhered to the other side of the wound and has a second fixing seat. One end of the tensioning member is fixed to the first fixing seat, and the other end passes through the second fixing seat. The outer surface of the tensioning member has multiple cones, allowing any cone to be positioned with the second fixing seat. By pulling the tensioning member, the first and second patches are pulled closer together, thus closing the wound. This product's design is indeed suitable for longer wounds, eliminating the need for suturing at a medical facility and reducing pain during suturing and suture removal.

[0004] However, the aforementioned structure can only tighten in one direction and cannot loosen in the opposite direction. The wound can only be loosened by directly cutting the tightening element. For patients with slow wound healing (such as diabetic patients), it may be discovered that the wound has not yet healed after directly cutting the tightening element. This would waste the device, requiring the purchase of a new product to re-adhere and tighten the wound. Furthermore, this device tightens in stages, which may result in the wound being too tight, causing wound deformation, or too loose, causing future scarring. In other words, this device has the problem of not being able to achieve the optimal tightness for wound closure.

[0005] Furthermore, while Taiwan Patent No. M587989 can resolve the issues of the aforementioned US Patent Publication No. US2016 / 0220252A1, it still has the following problems:

[0006] 1. The case uses too many screws, which takes a lot of time to assemble and users to adjust. Each screw is adjusted individually with different distances, resulting in crooked and unsightly joints.

[0007] 2. If a single screw is used, it is usually placed in the middle. The two sides are far away from the screw. Because the first adhesive sheet 20 and the second adhesive sheet 30 are relatively soft, when adjusting the screw, there will be deformation problems in the middle of the screw and the ends on both sides. Therefore, the middle part has been adjusted to the predetermined position, but the two sides are not yet in the predetermined position. This results in the wound in the middle being joined together, but the wounds on both sides not yet joined together.

[0008] 3. The wound is located between the first adhesive sheet 20 and the second adhesive sheet 30, which means it is exposed to the outside and easily affected by external impacts or by dirt and water stains, causing greater damage to the wound. Utility Model Content

[0070] To provide a better understanding and appreciation of the features and characteristics of this utility model, the following preferred embodiments are provided in conjunction with the accompanying drawings:

[0071] Please see Figures 1A to 3D A preferred embodiment of the present invention provides a wound fixation device 100, which includes a bottom protective film 10, a first adhesive sheet 20, a second adhesive sheet 30, a screw 40, an upper plate 60, and a top protective film 50, wherein:

[0072] In this embodiment, the bottom protective film 10 is a release paper, which allows the first adhesive sheet 20, the second adhesive sheet 30, and the top protective film 50 to be separably adhered together.

[0073] In this embodiment, the first adhesive sheet 20 includes a first fixing piece 21, a first adhesive 22, a first fixing seat 23, a first slider 25, and a second slider 26. The first fixing piece 21 is an elongated thin sheet. The first adhesive 22 is fixed to the bottom surface of the first fixing piece 21. The first fixing seat 23 is integrally connected to the top surface of the first fixing piece 21 and protrudes, and has a through pivot hole 231. The first slider 25 is integrally connected to the top surface of the first fixing piece 21 and protrudes, and has a first sliding groove 251. The second slider 26 is integrally connected to the top surface of the first fixing piece 21 and protrudes, and has a second sliding groove 261. The first slider 25 and the second slider 26 are symmetrically disposed on both sides of the first fixing seat 23. The first adhesive 22 of the first adhesive sheet 20 is adhered to the top surface of the bottom protective film 10 in a peelable manner.

[0074] In this embodiment, the second adhesive sheet 30 includes a second fixing piece 31, a second adhesive 32, a second fixing seat 33, a third slider 35, and a fourth slider 36. The second fixing piece 31 is an elongated thin sheet. The second adhesive 32 is fixed to the bottom surface of the second fixing piece 31. The second fixing seat 33 is integrally connected to the top surface of the second fixing piece 31 and protrudes, and has a through screw hole 331. The third slider 35 is integrally connected to the top surface of the second fixing piece 31 and protrudes, and has a third groove 351. The fourth slider 36 is integrally connected to the top surface of the second fixing piece 31 and protrudes, and has a fourth groove 361. The second adhesive 32 of the second adhesive sheet 30 is peelably adhered to the top surface of the bottom protective film 10, and the second adhesive sheet 30 is parallel to the first adhesive sheet 20.

[0075] In this embodiment, the screw 40 is integrally formed and sequentially defines a head 41, a pivot portion 42, an external thread portion 43, and a drive portion 44. The outer diameter of the head 41 is larger than the diameter of the pivot hole 231 of the first fixing seat 23; the outer diameter of the pivot portion 42 is smaller than the diameter of the pivot hole 231; the external thread portion 43 has an external thread 431; the outer diameter of the drive portion 44 is smaller than the diameter of the screw hole 331 of the second fixing seat 33, and the drive portion 44 is provided for the user to hold. The head 41 is located outside the first fixing seat 23, while the pivot portion 42 is located inside the pivot hole 231, the external thread 431 of the external thread portion 43 is screwed into the screw hole 331 of the second fixing seat 33 of the second adhesive sheet 30, and the drive portion 44 extends out from the outside of the second fixing seat 33.

[0076] The upper plate 60 is flat and has a first slide rail 61 and a second slide rail 62 at its bottom. The first slide rail 61 is integrally connected to and protrudes from the bottom surface of the upper plate 60, and is used to slide the first slider 25 and the third slider 35. The cross-section of the first slide rail 61 is, but not limited to, T-shaped. The second slide rail 62 is integrally connected to and protrudes from the bottom surface of the upper plate 60, and is used to slide the second slider 26 and the fourth slider 36. The cross-section of the second slide rail 62 is, but not limited to, T-shaped. With the above configuration, the first adhesive sheet 20 and the second adhesive sheet 30 can slide on the first slide rail 61 and the second slide rail 62. In another embodiment, the first adhesive sheet 20 is fixedly connected to the first slide rail 61, and the first adhesive sheet 20 is fixedly connected to the second slide rail 62. That is, the first slider 25 is fixed to the first slide rail 61, and the second slider 26 is fixed to the second slide rail 62. The fixing method can be tight fitting or glue. Therefore, the first slider 25 and the second slider 26 are basically non-functional and can be replaced by other components or methods.

[0077] In this embodiment, the bottom surface of the top protective film 50 has an adhesive 52. The top protective film 50 is adhered to the top surface of the bottom protective film 10 in a peelable manner by the adhesive 52, encapsulating the entire device and preventing water stains and dirt contamination.

[0078] Therefore, the above is an introduction to the components and assembly method of a wound fixation device 100 provided in a preferred embodiment of this utility model. Its usage features will then be described below:

[0079] When you wish to use this utility model, such as Figure 1CAs shown, firstly, the bottom protective film 10 is peeled off from the first adhesive 22 of the first adhesive sheet 20 and the second adhesive 32 of the second adhesive sheet 30, and then the top protective film 50 is peeled off from the bottom protective film 10. This allows the first adhesive 22 of the first adhesive sheet 20 to adhere to one side of the skin of the wound 91, while the second adhesive 32 of the second adhesive sheet 30 adheres to the other side of the skin of the wound 91 (as shown in Figure 4).

[0080] Next, the screw 40 can be rotated in one direction, as shown in Figure 5. The screw 40, through the connection of its external thread 431 and the screw hole 331, generates axial displacement, pushing the second adhesive sheet 30 towards the wound 91. Furthermore, the rotation of the screw 40 through the pivot 42 in place pushes the first adhesive sheet 20 towards the wound 91 through the head 41. In this way, the skin on both sides of the wound 91 is pulled closer, closing the wound 91 (as shown in Figure 6).

[0081] This invention allows wounds to close without the need for sutures, reducing travel time to medical facilities and eliminating the pain associated with suturing and suture removal. Furthermore, by using a linear stepless feed generated by the relative rotation of the external thread 431 and the threaded hole 331 to adjust the relative position between the first adhesive sheet 20 and the second adhesive sheet 30, this invention can precisely position the wound at the optimal tightness of closure, resulting in a more aesthetically pleasing scar after healing.

[0082] In addition, after using this invention for a period of time, if the user wants to observe the healing status of the wound, the screw 40 can be rotated in the opposite direction (as shown in Figure 7) to make the first adhesive sheet 20 and the second adhesive sheet 30 slightly separate. If the wound 91 has completely healed (as shown in Figure 8), the invention can be peeled off the skin. If the wound 91 has not completely healed (as shown in Figure 9), the screw 40 can be rotated again as shown in Figure 5 to pull the first adhesive sheet 20 and the second adhesive sheet 30 closer together to close the wound 91.

[0083] Because this invention can bring the first adhesive sheet 20 and the second adhesive sheet 30 closer together by rotating the screw 40 in the forward direction, and can also move the first adhesive sheet 20 and the second adhesive sheet 30 further apart by rotating the screw 40 in the reverse direction, it can provide a function to observe wound healing for people whose wounds heal slowly (especially for patients with diabetes).

[0084] Because the upper plate 60, the first slide rail 61, and the second slide rail 62 provide a robust and stable structure for the first adhesive sheet 20 and the second adhesive sheet 30, the first adhesive sheet 20 and the second adhesive sheet 30 can move smoothly and steadily in sync, completely closing the skin on both sides of the wound 91 without deformation or unsightly appearance. Moreover, the purpose and effect of this case can be achieved using only one screw, and the assembly and operation are simple and time-saving.

[0085] In addition, the upper plate 60 can provide protection for the wound. It can isolate dirt and foreign objects, and prevent external forces and objects from directly hitting the wound. Moreover, the upper plate 60 does not come into direct contact with the wound, so it has good ventilation and breathability, and will not cause the wound to ulcerate due to prolonged lack of air.

[0086] The above description is merely a preferred embodiment provided by this utility model, and is not intended to limit the scope of implementation of this utility model. All equivalent changes made by those skilled in the art based on this utility model should be included within the scope of this utility model.
