Abstract
Description
Technical Field
[0001] This disclosure belongs to the field of medical device technology, and in particular relates to a skin bonding device and method for promoting wound healing. Background Technology
[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.
[0003] Skin wound healing refers to the process of healing skin tissue after it has been severed or damaged due to external force. It includes a complex combination of regeneration of various tissues, proliferation of granulation tissue, and formation of scar tissue, showing the synergistic effect of various processes. The mildest trauma is limited to the epidermis, while more severe trauma involves rupture of the skin and subcutaneous tissue and the appearance of a wound. Severe trauma may involve the rupture of muscles, tendons, nerves, and fractures.
[0004] Existing skin-attachment devices include adhesive plates on both sides of the wound, plastic base beams on the inner sides of the adhesive plates, and a first base band and a second base band. The first base band has through holes, and the second base band has screw holes. Plastic screws are evenly spaced between the two plastic base beams. One end of the plastic screw is a limiting block, and the other end is a threaded post. The limiting block is used to fix the screw at the through hole. The distance between the two adhesive plates is adjusted by rotating the sleeve handle, thereby adjusting the force applied to the wound. However, the adhesive plates and plastic base beams are relatively rigid and not easy to bend, which can hinder the adhesion of the device to the skin in some curved body parts. Moreover, existing skin staplers, with plastic screws fixed at equal intervals on the plastic base beams, cannot be adjusted according to the size of the wound. Summary of the Invention
[0005] To address the aforementioned problems, this disclosure proposes a skin-adhesive device and method for promoting wound healing. This disclosure solves the problem that traditional skin-adhesive devices cannot meet the flexibility requirements of bent body parts, and at the same time, it can be adjusted according to the size of the wound to reduce secondary damage.
[0006] To achieve the above objectives, the first aspect of this disclosure provides a skin-adhesive device for promoting wound healing, employing the following technical solution:
[0007] A skin-adhesive device for promoting wound healing includes a base beam, an adhesive plate, and a plastic screw.
[0008] The base beam includes a first base beam and a second base beam, both of which are provided with elongated holes in the length direction;
[0009] The plastic screws are multiple in number, with one end passing through the elongated hole of the first base beam and the other end passing through the elongated hole of the second base beam; a first limiting block and a first nut are provided at the end of the plastic screws near the first base beam, and a second limiting block and a second nut are provided at the end of the plastic screws near the second base beam;
[0010] The adhesive plate includes a first adhesive plate fixed to the first base beam and a second adhesive plate fixed to the second base beam.
[0011] Furthermore, the base beam is provided with graduations.
[0012] Furthermore, the plastic screw includes a first plastic screw and a second plastic screw; the diameter of the first plastic screw is larger than the diameter of the second plastic screw.
[0013] Furthermore, a screw barrel is fitted over the second plastic screw, and the second plastic screw is threadedly connected to the screw barrel; the end of the first plastic screw away from the screw barrel is threaded and mates with the first nut; the end of the screw barrel away from the first plastic screw is threaded and mates with the second nut.
[0014] Furthermore, a screwing post is provided at the end of the second plastic screw away from the first plastic screw; the cross-section of the screwing post in the length direction is hexagonal.
[0015] Furthermore, the skin-adhesive device for promoting wound healing also includes a sleeve handle, one end of which is provided with a hexagonal hole that engages with the screwing column.
[0016] Furthermore, the base beam is made of liquid silicone, which is vulcanized silicone rubber.
[0017] Furthermore, the adhesive board uses a silicone indwelling pin adhesive, which includes a release protective layer, a silicone adhesive layer, a polyurethane film layer, and a release paper support layer arranged in sequence.
[0018] Furthermore, both the first limiting block and the second limiting block are conical blocks; the smaller diameter ends of the first limiting block and the second limiting block are positioned opposite each other, while the larger diameter ends are respectively close to the first base beam and the second base beam.
[0019] To achieve the above objectives, a second aspect of this disclosure provides a skin dressing method for promoting wound healing, employing a skin dressing device for promoting wound healing as provided in the first aspect; comprising the following:
[0020] Unscrew the first nut and the second nut outwards. The distance between the nut and the limiting block increases, and the plastic screw loosens. Move the plastic screw along the base beam to find the corresponding scale on the base beam. After determining the position, screw the first nut and the second nut inwards. The distance between the nut and the limiting block decreases. Clamp the base beam in the middle and fix the screw.
[0021] Install the sleeve handle and the plastic screw screw in sequence, then rotate the sleeve handle to move the first base beam, the second base beam and the adhesive plate closer to the wound to achieve the purpose of pressing the wound;
[0022] Alternatively, unscrew the first and second nuts outwards, increasing the distance between the nuts and the limiting block, loosening the plastic screws. Move the plastic screws along the base beam so that all the plastic screws are located on both sides of the wound. Find the corresponding scale on the base beam. After determining the position, screw the first and second nuts inwards, decreasing the distance between the nuts and the limiting block. Clamp the base beam in the middle, fix the screws, and cut off the excess adhesive plate and silicone base beam.
[0023] Compared with the prior art, the beneficial effects of this disclosure are as follows:
[0024] 1. The distance between each plastic screw in this disclosure is adjustable, which allows the spacing to be adjusted according to the wound condition.
[0025] 2. This disclosure allows for adjustment of the overall device size. By adjusting the screw positions, multiple screws can be positioned on both sides of the wound, satisfying the requirement that the skin patch with multiple plastic screws is closest to the wound size but still larger than the wound. This avoids the problem of some plastic screws not being usable. At the same time, it avoids direct contact between the patch and the skin at the wound site, ensuring that the wound receives sufficient nutrients during the healing process to the greatest extent possible, and preventing contamination by bacteria during the healing process, thus greatly reducing the risk of infection.
[0026] 3. The entire device in this disclosure is soft in texture and can deform well with the bending of the limbs in the bent parts of the body, which creates less resistance to the adhesion, thereby preventing the device from falling off and allowing the device to adhere tightly to the skin.
[0027] 4. This disclosure includes a matching intelligent sleeve handle, which can automatically determine the tightening degree caused by the rotation of the plastic screw by quantifying the rotational force, so that the four screws are kept at the same level of tightness, and there will be no situation of being too loose or too tight, or inconsistent tightness in different places; thus avoiding the slow healing, inflammation and swelling, and secondary damage to patients caused by unreasonable force on the wound when manually clamping.

[0034] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.
[0035] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0036] Example 1:
[0037] like Figure 1 As shown, this disclosure provides a skin bonding device for promoting wound healing, including a base beam 1, an adhesive plate 2, and plastic screws 3. In this embodiment, the base beam 1 includes a first base beam and a second base beam, both of which are provided with elongated holes along their length. There are multiple plastic screws 3, one end of which passes through the elongated hole of the first base beam, and the other end of which passes through the elongated hole of the second base beam. A first limiting block and a first nut 34 are provided at the end of the plastic screw 3 closest to the first base beam, and a second limiting block and a second nut 35 are provided at the end of the plastic screw 3 closest to the second base beam. Preferably, the number of plastic screws 3 is set to 4.
[0038] The adhesive plate 2 includes a first adhesive plate fixed to the first base beam and a second adhesive plate fixed to the second base beam; it is understood that the adhesive plate 2 and the base beam 1 can be fixed by adhesive bonding.
[0039] In this embodiment, the base beam 1 is provided with a scale. It can be understood that the scale is set on the side of the operator on the longitudinal surface of the base beam 1. Specifically, the base beam 1 is designed as a long cylindrical rod that runs through the left and right sides and is marked with a scale to determine the position of the plastic screw 3, so that after the medical staff moves the plastic screw 3, they can keep the plastic screw 3 perpendicular to the base beam 1 according to the scale.
[0040] like Figure 2 As shown, the plastic screw 3 includes a first plastic screw 31 and a second plastic screw 32; the diameter of the first plastic screw 31 is larger than the diameter of the second plastic screw 32; a screw barrel 33 is sleeved on the second plastic screw 32, and the second plastic screw 32 is threadedly connected to the screw barrel 33; the end of the first plastic screw 31 away from the screw barrel 33 is threaded and mates with the first nut 34; the end of the screw barrel 33 away from the first plastic screw 31 is threaded and mates with the second nut 35; a turning post 36 is provided at the end of the second plastic screw 32 away from the first plastic screw 31; the cross-section of the turning post 36 along its length is hexagonal.
[0041] In this embodiment, the skin bonding device for promoting wound healing also includes a sleeve handle 4. One end of the sleeve handle 4 is provided with a hexagonal hole (the hexagonal hole is located at the end of the sleeve handle 4, not shown in the figure), which cooperates with the screwing post 36. Specifically, when the sleeve handle 4 is used to tighten the plastic screw 3, the plastic screw 3 will drive the first adhesive plate to move closer to the wound and press the wound. When the sleeve handle 4 is used to rotate the plastic screw 3, the plastic screw 3 moves away from the wound, driving the first adhesive plate to move to the left and reducing the force applied to both sides of the wound. When the plastic screw 3 moves and closes the wound, the screw cylinder 33 does not move. Therefore, a certain gap needs to be set between the screw cylinder 33 and the first plastic screw 31.
[0042] The design incorporates an intelligent sleeve handle for tightening and pressurizing the plastic screw 3. This prevents inconsistent clamping force on the wound caused by inaccurate judgment of the tightness when manually rotating the screw. This avoids situations where the wound is not properly clamped in some areas, resulting in slow healing and infection, while the wound is clamped too tightly in others, leading to redness, swelling, and erosion.
[0043] In this embodiment, the base beam 1 is made of liquid silicone. Specifically, the liquid silicone (LSR) is a type of high-temperature vulcanized silicone rubber that is non-toxic and can undergo large deformation. In some curved body parts, it can deform well with the bending of the limbs, creating less resistance to the adhesion of the adhesive plate, thereby preventing the device from falling off and allowing the device to adhere tightly to the skin.
[0044] In this embodiment, the adhesive plate 2 uses a silicone indwelling needle patch. Using a silicone indwelling needle patch as the adhesive plate provides a soft texture, long adhesion time, no allergies, and painless removal. Specifically, the silicone indwelling needle patch includes, from bottom to top, a release protective layer, a silicone adhesive layer, a polyurethane film layer, and a release paper support layer. The polyurethane film layer is a solvent-based PU film, which can be prepared through the following process: first, prepare solvent-based polyurethane adhesive and double-sided glassine release paper, wherein the coated side of the glassine release paper is used for release. The release force is controlled between 200-500g, and the release force on the non-coating side of the glassine release paper is controlled between 30-200g. The nozzle gap for coating is set according to the thickness of the solvent-based PU film. Solvent-based polyurethane adhesive is applied to the coating side of the glassine release paper. Then, the glassine release paper coated with solvent-based polyurethane adhesive is conveyed into the drying oven via a conveyor belt. The glassine release paper and the conveyor belt are kept horizontally forward to avoid uneven thickness of the solvent-based PU film due to the angle between them. Finally, after drying, the required solvent-based PU film is produced.
[0045] By changing the materials of the adhesive plate 2 and the base beam 1, their elasticity is increased, making them easier to bend and deform, better fit the skin, and not fall off for a long time; the plastic screw 3 can move along the plastic base beam, and medical staff can adjust the spacing between the plastic screws according to the wound condition.
[0046] In this embodiment, both the first limiting block and the second limiting block are conical blocks; the smaller diameter ends of the first limiting block and the second limiting block are arranged opposite each other, and the larger diameter ends are respectively close to the first base beam and the second base beam.
[0047] The working principle or process of this embodiment is as follows:
[0048] When the plastic screw 3 is tightened along the thread using the sleeve handle 4, the plastic screw 3 moves the first adhesive plate closer to the wound, pressing the wound; when the plastic screw 3 is loosened along the thread using the sleeve handle 4, the plastic screw 3 moves away from the wound, moving the first adhesive plate away from the wound, reducing the force applied to both sides of the wound.
[0049] The end of the screw barrel 33 furthest from the first plastic screw 31 has a threaded section, which matches the second nut 35. After a distance equal to the diameter of the base beam 1, limiting blocks 37 with a diameter equal to or slightly larger than the base beam 1 are set on both sides of the central axis of the plastic screw 3 to lock the screw barrel 33. The end of the first plastic screw 31 furthest from the screw barrel 33 also has a threaded section, which matches the first nut 34. After a distance equal to the diameter of the base beam 1, limiting blocks 37 with a diameter equal to or slightly larger than the base beam 1 are set on both sides of the central axis of the plastic screw 3 to lock the first plastic screw 31. When the nut is screwed inward, the distance between the nut and the limiting block 37 decreases, clamping the base beam 1 in the middle to achieve the purpose of fixation. When the nut is screwed outward, the distance between the nut and the limiting block 37 increases, the plastic screw 3 loosens, and can move along the base beam 1.
[0050] Example 2:
[0051] This embodiment provides a skin bonding method to promote wound healing, employing the skin bonding device for promoting wound healing described in Embodiment 1; it includes the following:
[0052] Unscrew the first nut and the second nut outwards. The distance between the nut and the limiting block increases, and the plastic screw loosens. Move the plastic screw along the base beam to find the corresponding scale on the base beam. After determining the position, screw the first nut and the second nut inwards. The distance between the nut and the limiting block decreases. Clamp the base beam in the middle and fix the screw.
[0053] Install the sleeve handle and the plastic screw screw in sequence, then rotate the sleeve handle to move the first base beam, the second base beam, and the adhesive plate closer to the wound to achieve the purpose of pressing the wound.
[0054] Example 3:
[0055] This embodiment provides a skin bonding method to promote wound healing, employing the skin bonding device for promoting wound healing described in Embodiment 1; it includes the following:
[0056] Unscrew the first and second nuts outwards, increasing the distance between the nuts and the limiting block, loosening the plastic screws.

After determining the position, screw the first and second nuts inwards, decreasing the distance between the nuts and the limiting block. Clamp the base beam in the middle, fix the screws, and cut off the excess adhesive plate and silicone base beam.

Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
