Description

Technical Field

[0001] This utility model relates to the field of skin tension reducers, and in particular to a skin tension reducer for the maxillofacial region. Background Technology

[0002] For wounds or surgical incisions in the maxillofacial region, if traditional suture needles and sutures are used to close them, it will not only cause secondary damage to the skin tissue, but also cause the suture insertion point to be subjected to changing tension, which can easily lead to continuous tension on the wound during the healing process and cause scarring.

[0003] Currently, tension-reducing devices are being used clinically to address the issue of scarring after wound healing. However, the serrated bars on existing tension-reducing devices are difficult to remove from the locking mechanism, requiring the entire device to be removed for dressing changes, making operation inconvenient. Secondly, existing tension-reducing devices are generally designed for wounds on larger, flat areas such as the arms or legs, and their large size makes them unsuitable for facial wound treatment. Furthermore, the patches on both sides of existing tension-reducing devices rely mainly on adhesive tape to adhere to the skin surface, which is prone to failure when exposed to water without waterproofing, causing the device to detach. Additionally, existing tension-reducing devices lack operational guidance when tightening the serrated bars, easily leading to over-tightening in some areas, resulting in excessive traction on the skin for extended periods and potentially causing adverse effects such as tension blisters. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a skin tension reducer for the maxillofacial region, which solves the problems of the existing tension reducers having a thorn that is not easy to remove from the lock, a large size that makes it difficult to use for facial wound treatment, easy to fall off when wet, and lack of operation guidance.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0006] A skin tension reducer for the maxillofacial region includes a first patch and a second patch that adhere to both sides of a wound. Both the first and second patches have a waterproof protective membrane, and the waterproof protective membranes of the first and second patches have several closing components. Each closing component includes a ratchet mounted on the waterproof protective membrane of the second patch and a fixing block mounted on the waterproof protective membrane of the first patch. The surface of the ratchet has several ratchet teeth evenly distributed along its length. The fixing block has a first through hole, and the first through hole has a protrusion integrally formed with the fixing block. The protrusion divides the first through hole into a locking structure that communicates with each other and a non-locking structure that facilitates the removal of the ratchet from the fixing block. The locking structure includes two locking blocks installed in the first through hole and engaging with the ratchet teeth.

[0007] In one embodiment of this utility model, the first patch and the second patch are both made of hydrocolloid, and the distance between the first patch and the second patch is about 5mm to 7mm. The total width of the first patch and the second patch is about 22 to 26mm. The first patch and the second patch in this technical solution are made of hydrocolloid to achieve an adhesive effect.

[0008] In one embodiment of this utility model, the waterproof protective film is an ultra-thin polymer material, and the side of the waterproof protective film facing the first patch and the second patch that does not contact the first patch or the second patch is provided with acrylic adhesive. In this technical solution, the acrylic adhesive on the waterproof protective film can ensure that the hydrocolloid is completely sealed after bonding.

[0009] In one embodiment of the present invention, the closing component is made of a polymer material, the spacing between two adjacent closing components is about 4mm to 6mm, and a plurality of closing components are evenly installed on the waterproof protective film of the first patch and the second patch along the length direction of the first patch and the second patch.

[0010] In one embodiment of the present invention, the ratchet teeth of the ratchet are provided with a tightening position mark, which includes scale lines, color printing, or irregular shape of the ratchet teeth at that position.

[0011] As described above, the skin tension reducer for the maxillofacial region according to this utility model has the following beneficial effects:

[0012] This invention incorporates both locking and unlocking structures within the fixing block. When dressing changes are needed for the central wound, the thorn can be pulled out of the fixing block by moving it from the locking structure to the unlocking structure, thus exposing the central wound for dressing changes. The tension reducer in this invention is smaller than conventionally used tension reducers, making it suitable for wounds on the face and other areas with smaller skin areas. Furthermore, this invention covers the first and second patches with a waterproof protective film, preventing direct contact between moisture and the patches and reducing the probability of adhesion failure. The invention also marks the recommended tightening length on the thorn teeth of the thorn. During use, as long as the operator observes that the fixing block is within the marked color or scale range, it indicates that the tightness is within the appropriate range, avoiding skin damage caused by over-tightening.

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please see Figure 1 and Figure 2 This utility model provides a skin tension reducer for the maxillofacial region, including a first patch 1 and a second patch 2 that are adhered to both sides of a wound. The first patch 1 and the second patch 2 are made of hydrocolloid material and mainly serve an adhesive function. In this embodiment, please refer to the following for details. Figure 6The spacing between the first patch 1 and the second patch 2 is approximately 6 mm, and the total width of the first patch 1 and the second patch 2 is approximately 24 mm. In contrast, the spacing between the first patch 1 and the second patch 2 of existing conventional tension reducers is approximately 10 mm, and the total width of the first patch 1 and the second patch 2 is approximately 46 mm. It can be seen that the design size of this skin tension reducer is smaller than that of conventional tension reducers, making it suitable for wounds with small skin areas, such as those on the maxillofacial region. Both the first patch 1 and the second patch 2 are provided with a waterproof protective film 3. The waterproof protective film 3 can prevent direct contact between moisture and hydrocolloid, reducing the probability of adhesion failure. The waterproof protective film 3 is made of an ultra-thin polymer material, and the side of the waterproof protective film 3 facing the first patch 1 and the second patch 2 that does not contact the first patch 1 or the second patch 2 is provided with acrylic adhesive. The acrylic adhesive can ensure that the hydrocolloid is completely sealed after bonding.

[0024] like Figures 1 to 5 As shown, the waterproof protective film 3 of the first patch 1 and the second patch 2 is provided with a plurality of closing components 4. The closing components 4 are made of polymer material. The spacing between two adjacent closing components 4 is about 4mm to 6mm. The plurality of closing components 4 are evenly spaced and installed on the waterproof protective film 3 of the first patch 1 and the second patch 2 along the length direction. The closing components 4 include a ratchet 401 installed on the waterproof protective film 3 of the second patch 2 and a fixing block 402 installed on the waterproof protective film 3 of the first patch 1. The ratchet 401 is evenly spaced and installed on the waterproof protective film 3 of the second patch 2 along the length direction of the second patch 2. The fixing block 402 is evenly spaced and installed on the waterproof protective film 3 of the first patch 1 along the length direction of the first patch 1. A pull ring is provided on the side of the ratchet 401 away from the second patch 2. The pull ring is made of flexible material.

[0025] The surface of the ratchet 401 is provided with a plurality of ratchet teeth 5 evenly distributed along its length. A first through hole 7 is provided in the fixing block 402. A protrusion 8 integrally formed with the fixing block 402 is provided within the first through hole 7. The protrusion 8 divides the first through hole 7 into a locking structure 9 and a non-locking structure 10 that facilitates the removal of the ratchet 401 from the fixing block 402. The locking structure 9 includes two locking blocks 901 installed in the first through hole 7 and engaging with the ratchet teeth 5. The non-locking structure 10 includes a second through hole 1001 that facilitates the removal of the ratchet 401 from the fixing block 402. The second through hole 1001 is located within the first through hole 7. Furthermore, the top of the fixing block 402 is also provided with a connection to the first through hole. The third through hole 11 is connected to 7; after the skin tension reducer is assembled, multiple ratchet bars 401 are assembled together with their corresponding fixing blocks 402 to form a closed component 4. When the ratchet teeth 5 on the ratchet bar 401 are engaged with the locking block 901 in the locking structure 9, the closed component 4 is tightened and the skin tension reducer is in working condition. If the ratchet bar 401 is pushed to the non-locking structure 10 on the other side, the ratchet bar 401 can be pulled out to fully expose the wound in the middle, which is convenient for dressing change. The ratchet teeth 5 of the ratchet bar 401 are provided with a tightening position mark 6. The tightening position mark 6 includes, but is not limited to, scale lines, color printing, or making the shape of the ratchet teeth 5 at this position irregular for easy identification.

[0026] Specifically, when using the skin tension reducer, firstly, the first patch 1 is adhered to one side of the wound. After positioning, the second patch 2 is adhered to the other side of the wound. Then, the ratchet 5 on the ratchet 401 engages with the locking block 901 inside the locking structure 9, and each ratchet 401 is tightened. Referring to the suggested position markings on the ratchet 401, ensure that the fixing block 402 is within the marked range on the ratchet 401. This avoids excessive tightening that could cause facial skin damage. The skin wound is closed by the tightening of the ratchet 401 in the closing component 4, avoiding secondary damage to the skin caused by sutures. Figure 1 and Figure 2 The skin tension reducer is in the state where the ratchet 5 on the ratchet bar 401 is engaged with the locking block 901 inside the locking structure 9. If it is necessary to remove the ratchet bar 401 from the fixing block 402, the ratchet 5 on the ratchet bar 401 needs to be pushed to the non-locking structure 10 on the other side. At this time, the ratchet 5 disengages from the two locking blocks 901, and since the pull ring is made of a flexible material, the ratchet bar 401 can be pulled out, thus fully exposing the wound in the middle for easy dressing changes. Please refer to [link / reference needed] for details. Figure 7 .

[0027] In summary, this invention uses adhesive tape to fix the wound to the skin surface, and the closure component 4 uses the ratchet 401 in the closure assembly 4 to tighten and close the wound, avoiding secondary damage to the skin caused by sutures. This invention incorporates a locking structure 9 and a non-locking structure 109 within the fixing block 402. When dressing changes are needed, the ratchet 401 can be pulled out of the fixing block 402 by moving it from the locking structure 9 to the non-locking structure 109, thus facilitating the exposure of the wound for dressing changes. The tension reducer in this invention is designed to be smaller than... The commonly used tension reducer is suitable for wounds on the face and jaw where the skin area is relatively small. Furthermore, this invention includes a waterproof protective film 3 covering the first patch 1 and the second patch 2. This film prevents direct contact between moisture and the first patch 1 and the second patch 2, reducing the probability of adhesion failure. Additionally, this invention marks the recommended tightening length on the ratchet teeth 5 of the ratchet bar 401. During use, as long as the operator observes that the fixing block 402 is within the marked color or scale range, it indicates that the tightness is within the appropriate range, avoiding skin damage caused by excessive tightening.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
