Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a ring-shaped tension reducer, which is particularly suitable for the healing of circular wounds, such as those resulting from abdominal plastic surgery. Background Technology
[0002] Tension reducers are commonly used for continuous tension reduction in postoperative wounds, which can reduce scarring and promote wound healing. Abdominal plastic surgery often preserves the umbilicus by stretching the abdominal skin and creating a new umbilicus. However, the scar between the new skin and the old umbilicus tissue requires the use of tension reducers to achieve a tension-reducing effect and improve surgical outcomes. Existing tension reducers are not suitable for the circular wounds created in abdominal plastic surgery. Patients need to cut existing tension reducers to the appropriate shape, which is inconvenient. Furthermore, wrinkles and curling can occur during application, affecting the adhesive adhesion and resulting in unsatisfactory tension reduction. Utility Model Content
[0003] In order to solve the technical problems existing in the prior art, the embodiments of this utility model provide a ring-shaped tension reducer, which is suitable for circular wounds generated in abdominal wall plastic surgery and can achieve a good tension reduction effect.
[0004] An embodiment of this utility model provides an annular tension reducer. The annular tension reducer includes: an annular substrate, including a first substrate and a second substrate disposed opposite each other in a horizontal direction; an annular adhesive layer disposed on the bottom surface of the annular substrate, the annular adhesive layer including a first adhesive layer and a second adhesive layer disposed opposite each other in a horizontal direction; and a plurality of closing components disposed on the top surface of the annular substrate for connecting the first substrate and the second substrate; wherein the first substrate and the second substrate are spaced apart by a first distance, the first substrate has a first groove, and the second substrate has a second groove disposed opposite to the first groove; wherein the first adhesive layer and the second adhesive layer are spaced apart by a second distance, the first adhesive layer has a third groove corresponding to the first groove, and the second adhesive layer has a fourth groove corresponding to the second groove.
[0005] In some embodiments, the width of the first groove, the second groove, the third groove, and the fourth groove is 1 mm to 10 mm, and the depth is 1 mm to 10 mm.
[0006] In some embodiments, the first distance and / or the second distance is 1 mm to 15 mm.
[0007] In some embodiments, the annular tension reducer further includes a backing paper disposed on the top surface of the annular substrate.
[0008] In some embodiments, the backing paper is provided with a tearing handle for separating the backing paper.
[0009] In some embodiments, the annular tension reducer further includes release paper disposed on the bottom surface of the annular adhesive layer.
[0010] In some embodiments, the backing paper and / or the release paper are made of glassine paper, PP, PET or PE material.
[0011] In some embodiments, the annular substrate is made of TPU, PU, or nonwoven fabric.
[0012] In some embodiments, the annular adhesive layer is made of hydrocolloid.
[0013] In some embodiments, the plurality of closure components are arranged in an alternating manner.
[0014] In some embodiments, each closure component includes a pull rod and a snap fastener that engages with the pull rod.
[0015] In some embodiments, the buckle is provided with a latch for locking the pull rod.
[0016] In some embodiments, the pull rod and the buckle are made of PA material.
[0017] In some embodiments, the buckle is provided with a tensioning channel and a retraction channel. When the pull rod is in the tensioning channel, the pull rod can move unidirectionally along the tensioning channel. When the pull rod is in the retraction channel, the pull rod can move bidirectionally along the retraction channel.
[0018] In some embodiments, the thickness of the annular substrate is 0.2 mm to 1.5 mm, and the thickness of the annular adhesive layer is 0.2 mm to 0.8 mm.
[0019] In the annular tension reducer according to an embodiment of the present invention, a first substrate and a second substrate are spaced apart by a first distance. The first substrate has a first groove, and the second substrate has a second groove opposite to the first groove. A first adhesive layer and a second adhesive layer are spaced apart by a second distance. The first adhesive layer has a third groove corresponding to the first groove, and the second adhesive layer has a fourth groove corresponding to the second groove. During use, these grooves are located around the wound, preventing the annular adhesive layers from being squeezed together when the product shrinks, thus preventing the annular adhesive layers from failing. The first distance between the first substrate and the second substrate, and the second distance between the first adhesive layer and the second adhesive layer, prevents abdominal folds from affecting the adhesion of the annular adhesive layer when the body switches between sitting and lying down, specifically reducing the probability of the annular adhesive layer detaching from the skin after folding, thereby improving the tension reduction effect. Attached Figure Description
[0020] Other features and advantages of this utility model will be better understood through the following detailed description of optional embodiments in conjunction with the accompanying drawings, in which the same reference numerals denote the same or similar parts, wherein:
[0021] Figure 1 A schematic diagram of the structure of a ring-shaped tension reducer according to an embodiment of the present invention is shown; and
[0022] Figure 2 It shows Figure 1 Exploded view of the annular tension reducer of the embodiment shown. Detailed Implementation
[0023] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways of implementing and using the present invention, and are not intended to limit the scope of the present invention. In the description, the structural positions of the various components, such as upper, lower, top, bottom, etc., are not absolute but relative. These directional descriptions are appropriate when the various components are arranged as shown in the figures, but these directional descriptions also change accordingly when the positions of the various components in the figures change.
[0024] Figure 1 A schematic diagram of the structure of an annular tension reducer 100 according to an embodiment of the present invention is shown; and Figure 2 It shows Figure 1 Exploded view of the annular tension reducer 100 of the embodiment shown.
[0025] like Figure 1 and Figure 2As shown, the annular tension reducer 100 includes an annular substrate 10, an annular adhesive layer 20, and a plurality of closing components 30. The annular substrate 10 includes a first substrate 11 and a second substrate 12 disposed opposite each other in a horizontal direction. The annular adhesive layer 20 is disposed on the bottom surface of the annular substrate 10, and includes a first adhesive layer 21 and a second adhesive layer 22 disposed opposite each other in a horizontal direction. The plurality of closing components 30 are disposed on the top surface of the annular substrate 10. The first substrate 11 and the second substrate 12 are spaced apart by a first distance D1. The first substrate 11 has a first groove 111, and the second substrate 12 has a second groove 121 disposed opposite to the first groove 111. The first adhesive layer 21 and the second adhesive layer 22 are spaced apart by a second distance D2. The first adhesive layer 21 has a third groove 211 corresponding to the first groove 111, and the second adhesive layer 22 has a fourth groove 221 corresponding to the second groove 121.
[0026] In use, the annular tension reducer 100 is attached to the skin around a circular wound, such as that created during abdominal plastic surgery. The first groove 111, the second groove 121, the third groove 211, and the fourth groove 221 form a space to surround the circular wound, which can prevent the annular adhesive layer 20 from being squeezed together when the product shrinks, thus preventing the annular adhesive layer 20 from failing.
[0027] In some embodiments, the thickness of the annular substrate 10 is 0.2 mm to 1.5 mm, and the thickness of the annular adhesive layer 20 is 0.2 mm to 0.8 mm. The annular substrate 10 is made of an elastomer material, such as TPU or PU, or it can be made of a non-woven fabric material. The annular adhesive layer 20 is made of a hydrocolloid, or it can be made of other medical adhesives. The annular substrate 10 is adhered to the annular adhesive layer 20 by the adhesiveness of the annular adhesive layer 20, the first substrate 11 is adhered to the first adhesive layer 21, and the second substrate 12 is adhered to the second adhesive layer 22. The annular adhesive layer 20 is made of a hydrocolloid, which can reduce the foreign body sensation when the closure component 30 is applied to the skin around the wound, and can be applied to the human body for more than 7 days without adverse symptoms such as allergic reactions.
[0028] In some embodiments, the width of the first groove 111, the second groove 121, the third groove 211, and the fourth groove 221 is 1 mm to 10 mm, and the depth is 1 mm to 10 mm. The shape of the first groove 111, the second groove 121, the third groove 211, and the fourth groove 221 can be any shape, such as rectangular, trapezoidal, or arc-shaped, and the embodiments of this utility model do not limit this.
[0029] In some embodiments, the first distance D1 between the first substrate 11 and the second substrate 12 is 1 mm to 15 mm, for example, the first distance D1 is 5 mm, 10 mm, 15 mm, etc.; the second distance between the first adhesive layer 21 and the second adhesive layer 22 is 1 mm to 15 mm, for example, the second distance D2 is 5 mm, 10 mm, 15 mm, etc. In some embodiments, the first distance D1 and the second distance D2 are substantially the same.
[0030] In some embodiments, the annular tension reducer 100 further includes a backing paper 40 disposed on the top surface of the annular substrate 10. The backing paper 40 may be a paper backing, such as glassine paper, or may be made of materials such as PP, PET, or PE. The thickness of the backing paper 40 is 0.01 mm to 0.9 mm.
[0031] In some embodiments, the backing paper 40 is substantially annular and includes a first backing paper 41 and a second backing paper 42 disposed opposite each other in a horizontal direction. The first backing paper 41 is disposed on the top surface of the first substrate 11, and the second backing paper 42 is disposed on the top surface of the second substrate 12.
[0032] In some embodiments, a third distance D3 is provided between the first backing paper 41 and the second backing paper 42. The third distance D3 between the first backing paper 41 and the second backing paper 42 is 1 mm to 15 mm, for example, 5 mm, 10 mm, 15 mm, etc. In some embodiments, the third distance D3 is substantially the same as the first distance D1 and the second distance D2.
[0033] In some embodiments, the backing paper 40 is provided with tearing handles 43 for separating the backing paper 40. Four tearing handles 43 are shown in the figure, which facilitates tearing the backing paper 40 from any position. There is a partition paper below the tearing handles 43, so that the tearing handles 43 are non-sticky and can be easily separated from the annular substrate 10.
[0034] In some embodiments, the annular tension reducer 100 further includes a release liner 50 disposed on the bottom surface of the annular adhesive layer 20. The release surface of the release liner 50 faces the annular adhesive layer 20. In use, the release liner 50 is peeled off from the annular adhesive layer 20. The release liner 50 can be made of glassine paper, or it can be made of materials such as PP, PET, or PE.
[0035] Because the annular tension reducer 100 is relatively thin and light, wrinkles and curling may occur during bonding. The backing paper 40 can be peeled off after the annular adhesive layer 20 is bonded to the skin, giving the annular adhesive layer 20 a certain structural strength after separation from the release paper 50, preventing product deformation. The backing paper 40 has a light release adhesive on the side adjacent to the annular substrate 20, which can prevent damage to the tightness of the product's adhesion to the skin during peeling.
[0036] In some embodiments, each closure component 30 includes a pull rod 31 and a buckle 32 that cooperates with the pull rod 31. One end of the pull rod 31 is provided with a pull ring 311 for pulling the pull rod 31, and the other end is provided with a base 312 for fixing to the annular base plate 10. The pull rod 31 and the buckle 32 are plastic parts made of PA material, thereby ensuring that the product has a certain structural strength and flexibility.
[0037] In some embodiments, the pull rod 31 is provided with a plurality of toothed grooves 313, and the buckle 32 is provided with a latch 321 for locking the toothed grooves 313 of the pull rod 31. In some embodiments, the buckle 32 is provided with a tensioning channel 322 and a retraction channel 323. When the pull rod 31 is in the tensioning channel 322, the pull rod 31 can move unidirectionally along the tensioning channel 322. When the pull rod 31 is in the retraction channel 323, the pull rod 31 can move bidirectionally along the retraction channel 323, thereby realizing the tensioning and retraction functions of the pull rod 31.
[0038] When using, first peel off the release layer 50, then attach the annular adhesive layer 20 to the skin around the wound, and then adjust each closure component 30 to reduce the tension of the skin around the wound and achieve the effect of tension reduction.
[0039] like Figure 1 As shown, multiple closure components 30 are arranged in an alternating pattern. On one side of the first substrate 11, the pull rod 31 of one closure component 30 is fixed to the first substrate 11, and the latch 32 is fixed to the second substrate 12. Similarly, the pull rod 31 of an adjacent closure component 30 is fixed to the second substrate 12, and the latch 32 is fixed to the first substrate 11. On the other side of the second substrate 12, the pull rod 31 of one closure component 30 is fixed to the second substrate 12, and the latch 32 is fixed to the first substrate 11. Likewise, the pull rod 31 of an adjacent closure component 30 is fixed to the first substrate 11, and the latch 32 is fixed to the second substrate 12.
[0040] By using cross-tension to tighten, tension reduction is achieved with minimal operation, while ensuring even pressure on the skin for optimal results. The grooved design of the hydrocolloid prevents deformation when the product is pulled, and the gap between the two hydrocolloid sheets prevents abdominal wrinkles from affecting the hydrocolloid's fit when switching between sitting and lying positions, effectively reducing the probability of the hydrocolloid detaching from the skin due to wrinkles. The addition of a backing paper design allows the product to be as thin as possible while preventing it from failing due to its own wrinkles when adhering to the skin. The product can achieve a tension reduction range of up to 15mm.
[0041] The technical content and features of this utility model have been disclosed above. However, it is understood that, under the creative concept of this utility model, those skilled in the art can make various changes and improvements to the disclosed concept, all of which fall within the protection scope of this utility model. The description of the above embodiments is illustrative rather than restrictive, and the protection scope of this utility model is determined by the claims.
