Description

Technical Field

[0001] This utility model relates to the field of skin wound suture device technology, and in particular to a disposable skin suture tension reducer. Background Technology

[0002] The skin wound closure device includes a zipper-type closure mechanism with medical adhesive tape on both sides. Through the interlocking of the zipper-like toothed structure, the one-way sliding buckle gradually tightens the skin on both sides of the wound, reducing wound tension.

[0003] Most existing zipper-type closure devices are designed for one-way tightening and cannot be pulled in reverse. If the closure is too tight and causes local ischemia, the device must be cut off and the operation repeated, which is quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disposable skin suture tension reducer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A disposable skin suture tension reducer includes a first adhesive sheet and a second adhesive sheet arranged symmetrically. Each of the first adhesive sheet and the second adhesive sheet has a peelable isolation sheet at one end. The other ends of the first adhesive sheet and the second adhesive sheet and adjacent sides are respectively provided with a plurality of first buckle components and second buckle components at equal distances. The first buckle components and the second buckle components are arranged symmetrically. Both the first and second snap-fit ​​components include a base. A second lateral fixing block is fixedly installed on one side of the base. A first deformation block, a locking block, and a first lateral fixing block are installed at equal intervals on one end of the second lateral fixing block. A second deformation block is connected to one side between the first deformation block and the locking block. A rack and pinion assembly is fixedly installed on the other side of the base and between the first deformation block and the locking block.

[0006] Furthermore, in a preferred configuration, the lateral fixing block is fixedly connected to the base.

[0007] Furthermore, in a preferred configuration, the rack assembly includes a rack body, on which multiple unidirectional helical teeth are equidistantly arranged on one side of the rack body facing the second fixed block, and the top surface of each unidirectional helical tooth is located at the end away from the locking block. Multiple anti-slip protrusions are equidistantly installed on one end of the rack body and on the side away from the unidirectional helical teeth.

[0008] Furthermore, in a preferred configuration, the locking block is provided with a plurality of locking teeth at equal intervals on the side of the rack assembly that engage with the unidirectional oblique teeth of the rack body.

[0009] Furthermore, in a preferred configuration, a fixing protrusion is installed at one end of the lateral fixing block and between the first deformable block and the locking block, and the end face of the fixing protrusion near the locking block is flush with the end face of the rack body near the locking block.

[0010] Furthermore, in a preferred configuration, a guide hole is provided through the first and second deformation blocks of the lateral fixing block and between the fixing protrusion and the locking block, allowing the rack body to pass through, and the cross-sectional area of ​​the guide hole is consistent with the cross-sectional area of ​​the rack assembly.

[0011] The beneficial effects of this utility model are as follows: In this invention, the first and second snap fasteners are symmetrically arranged, which allows the first and second adhesive sheets to move evenly and smoothly toward the center of the wound and to bring the skin on both sides of the wound toward the wound, thereby reducing skin tension at the wound site and indirectly assisting wound healing. At the same time, if the first and second adhesive sheets are too close together, the distance can be adjusted in the opposite direction. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5A disposable skin suture tension reducer includes a first adhesive sheet 1 and a second adhesive sheet 2 arranged symmetrically. One end of each of the first adhesive sheet 1 and the second adhesive sheet 2 is provided with a peelable isolation sheet 4, and multiple first buckle components 3-1 and second buckle components 3-2 are arranged at equal distances on the other end of the first adhesive sheet 1 and the second adhesive sheet 2 on adjacent sides. The first buckle components 3-1 and the second buckle components 3-2 are arranged symmetrically. Meanwhile, both the first snap-fit ​​assembly 3-1 and the second snap-fit ​​assembly 3-2 include a base 31. A second lateral fixing block 322 is fixedly installed on one side of the base 31. A first deformation block 323, a locking block 325, and a first lateral fixing block 321 are installed at equal distances on one end of the second lateral fixing block 322. A second deformation block 324 is connected to one side between the first deformation block 323 and the locking block 325. A rack assembly is fixedly installed on the other side of the base 31 and between the first deformation block 323 and the locking block 325.

[0016] Furthermore, the lateral fixing block 321 is fixedly connected to the base 31.

[0017] Furthermore, the rack assembly includes a rack body 33, on which multiple unidirectional oblique teeth are equally spaced along the side of the rack body 33 toward the fixed stop 322, and the top surface of each unidirectional oblique tooth is located at the end away from the locking block 325. Multiple anti-slip protrusions 34 are equally spaced along one end of the rack body 33 away from the unidirectional oblique teeth. With the anti-slip protrusions 34, the rack body 33 is not easy to slip when the fingertip grips it and pulls.

[0018] Furthermore, the locking block 325 has multiple locking teeth that mesh with the unidirectional oblique teeth of the rack body 33 at equal intervals on the side near the rack assembly.

[0019] Meanwhile, a fixing protrusion is installed at one end of the lateral fixing block 322 and between the first deformation block 323 and the locking block 325, and the end face of the fixing protrusion near the locking block 325 is flush with the end face of the rack body 33 near the locking block 325.

[0020] Meanwhile, a guide hole is provided through the lateral fixed stop block 321 and the second deformation block 324, and between the fixed protrusion and the locking block 325, for the rack body 33 to pass through, and the guide hole plays a limiting role for the rack assembly.

[0021] In this embodiment, by peeling off the isolation sheet 4 and symmetrically applying the first adhesive sheet 1 and the second adhesive sheet 2 to both sides of the wound, and then pulling the end of the corresponding toothed body 33 one by one, and pressing the fingertip to the anti-slip protrusion 34, the toothed body 33 of the first buckling assembly 3-1 and the locking block 325 of the second buckling assembly 3-2 are locked in one direction, and the toothed body 33 of the second buckling assembly 3-2 and the locking block 325 of the first buckling assembly 3-1 are locked in one direction, driving the first adhesive sheet 1 and the second adhesive sheet 2 to move closer to the center of the wound, and causing the skin on both sides of the wound to move closer to the wound, so as to reduce the skin tension at the wound and indirectly assist the wound healing.

[0022] When the first adhesive piece 1 and the second adhesive piece 2 are too close together, and it is necessary to increase the distance between the first adhesive piece 1 and the second adhesive piece 2, the lateral fixing block 321 and the first deformation block 324 can be pinched at the same time, and the first deformation block 324 can be pressed to move to the side of the lateral fixing block 321. During the movement of the first deformation block 324, the second deformation block 324 and the locking block 325 are driven to move to the side of the lateral fixing block 321. The pressing action forces the locking teeth of the locking block 325 to disengage from the rack body 33. Then, the rack body 33 can be pulled in the opposite direction to achieve the distance adjustment.

[0023] Furthermore, after the pressure is released, the first deformation block 324, the second deformation block 324, and the locking block 325 automatically reset under their own elasticity, and the locking block 325 re-engages with the rack body 33 and locks itself.

[0024] In this invention, the first snap fastener assembly 3-1 and the second snap fastener assembly 3-2, which are symmetrically arranged, can make the first adhesive sheet 1 and the second adhesive sheet 2 move towards the center of the wound evenly and stably, and make the skin on both sides of the wound move towards the wound, so as to reduce the skin tension at the wound and play an indirect auxiliary role in wound healing. At the same time, if the first adhesive sheet 1 and the second adhesive sheet 2 are too close together, the distance can be adjusted in the opposite direction.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
