Abstract
Description
Technical Field
[0001] This utility model relates to the field of minimally invasive postoperative wound dressing technology, specifically a minimally invasive postoperative wound dressing with wound closure function. Background Technology
[0002] Minimally invasive surgery, as the name suggests, involves minimal trauma. It refers to surgeries performed using modern medical instruments and equipment such as laparoscopes and thoracoscopes. The advantages of minimally invasive surgery include less trauma, less pain, and faster recovery, making it a dream for every patient requiring surgery. The wounds left after minimally invasive surgery generally do not require sutures; instead, post-operative bandages are typically used to close the wound, promoting rapid healing and protecting the wound.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Commonly used wound dressings after minimally invasive surgery may not have the corresponding wound closure function, which is not conducive to the rapid healing of wounds and reduces the healing efficiency; 2. When commonly used wound dressings after minimally invasive surgery are adhered to the wound for a long time, tissue fluid will be produced at the wound site. This tissue fluid may not be effectively treated, which will lead to a reduction in the wound healing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a minimally invasive postoperative wound dressing with wound closure function to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A minimally invasive postoperative wound dressing with wound closure function, comprising an adhesive layer, release paper installed on both sides of the bottom of the adhesive layer, low-sensitivity adhesive tape evenly installed on both sides of the top of the adhesive layer, a sterilization layer embedded in the middle of the adhesive layer, an absorbent layer installed on top of the sterilization layer, a breathable layer installed on top of the absorbent layer, main Velcro fasteners installed on both sides of the top of the adhesive layer located on the breathable layer, limit blocks evenly installed on both sides of the top of the adhesive layer located on the breathable layer, and a first elastic band and a second elastic band evenly installed on both sides of the top of the adhesive layer located on the breathable layer.
[0005] More preferably, the absorbent layer is made of a highly absorbent resin.
[0006] More preferably, the breathable layer is made of polyurethane film.
[0007] More preferably, the bottom of the absorbent layer is provided with an anti-sticking coating, and the material is polytetrafluoroethylene.
[0008] More preferably, the low-sensitivity adhesive tape is provided in six parts, and is symmetrically distributed about the central axis of the bonding layer.
[0009] More preferably, both the first elastic band and the second elastic band have a secondary Velcro strap installed at their bottoms.
[0010] More preferably, the first elastic band and the second elastic band are horizontally installed through the inner side of the limiting block.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] In this invention, a first elastic band and a second elastic band are added. When the bandage is applied to the wound surface, the first and second elastic bands can be pulled to pull the two sides of the adhesive layer, thereby effectively closing the wound. After achieving the desired effect, the main and secondary hook and loop fasteners can be used to maintain the wound's closure, increasing the efficiency of wound healing, effectively reducing the risk of wound dehiscence, and enabling the wound to heal quickly.
[0013] In this invention, an absorbent layer is added, and the material is highly absorbent resin. This allows the absorbent layer to quickly absorb the tissue fluid exuded from the wound during the healing process, keeping the wound dry and helping to reduce the risk of wound infection. This, in turn, helps to promote wound healing, while reducing pain and irritation, effectively improving healing efficiency and patient comfort. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a minimally invasive postoperative wound dressing with wound closure function, comprising an adhesive layer 1, release paper 2 installed on both sides of the bottom of the adhesive layer 1, low-sensitivity adhesive tape 3 evenly installed on both sides of the top of the adhesive layer 1, a disinfection layer 4 embedded in the middle of the adhesive layer 1, an absorbent layer 5 installed on the top of the disinfection layer 4, a breathable layer 6 installed on the top of the absorbent layer 5, main Velcro 7 installed on both sides of the breathable layer 6 on the top of the adhesive layer 1, limiting blocks 8 evenly installed on both sides of the breathable layer 6 on the top of the adhesive layer 1, and a first elastic band 9 and a second elastic band 10 evenly installed on both sides of the breathable layer 6 on the top of the adhesive layer 1.
[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the absorbent layer 5 is made of highly absorbent resin. This design allows the absorbent layer 5 to quickly absorb tissue fluid exuded from the wound during the healing process, keeping the wound dry and helping to reduce the risk of wound infection, thereby promoting wound healing.
[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the breathable layer 6 is made of polyurethane film. This design ensures good air permeability, guarantees gas exchange at the wound site, promotes wound healing, and effectively prevents water, dirt, or other external contaminants from penetrating into the wound, protecting the wound from the risk of infection and increasing wound healing efficiency.
[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the absorbent layer 5 is equipped with an anti-adhesion coating, and the material is polytetrafluoroethylene. This design effectively prevents the absorbent layer 5 from sticking to the wound, thus avoiding secondary damage to the wound when changing the bandage.
[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, there are six hypoallergenic adhesive tapes 3, which are symmetrically distributed about the central axis of the adhesive layer 1. This design allows the hypoallergenic adhesive tapes 3 to further limit the position of the wound after it has been closed, effectively preventing the bandage from shifting, increasing the protection of the wound, and thus further increasing the wound healing efficiency.
[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the first elastic band 9 and the second elastic band 10 have auxiliary Velcro straps installed at their bottoms. This design allows the first elastic band 9 and the second elastic band 10 to be pulled to pull the two sides of the adhesive layer 1, thereby enabling the wound to close effectively. After achieving the desired effect, the main Velcro strap 7 and the auxiliary Velcro straps can be bonded together to keep the wound closed, thus increasing the efficiency of wound healing and reducing the risk of wound dehiscence.
[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first elastic band 9 and the second elastic band 10 are horizontally installed inside the limiting block 8. This design allows the first elastic band 9 and the second elastic band 10 to slide inside the limiting block 8 when adjusting the closure of the wound, thereby increasing the limiting effect and effectively avoiding the possibility of damage to the wound.
[0027] The method of use and advantages of this utility model: This minimally invasive postoperative wound dressing with wound closure function works as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, tear off the release paper 2 and attach the adhesive layer 1 around the wound, so that the disinfectant layer 4 adheres to the wound. Then, pull the first elastic band 9 and the second elastic band 10. The two sides of the adhesive layer 1 will move the two sides of the wound in opposite directions, thereby closing the wound. Under the limiting action of the limiting block 8, the possibility of damage to the wound is effectively avoided. When the wound is closed, attach the secondary Velcro at the bottom of the first elastic band 9 and the second elastic band 10 to the main Velcro 7. At the same time, attach the hypoallergenic tape 3 to effectively prevent the wound from opening. The displacement of the adhesive layer further enhances the wound closure effect. While the wound is healing, the disinfection layer 4 disinfects, and the tissue fluid produced during the healing process is absorbed by the absorbent layer 5, ensuring the wound remains dry and increasing healing efficiency. The breathable layer 6 allows air to pass through while preventing water, dirt, or other external pollutants from penetrating into the wound, protecting it from the risk of infection. When the wound heals or needs to be replaced, the anti-adhesion coating installed at the bottom of the absorbent layer 5 effectively prevents secondary damage to the wound.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
