Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a suture-free patch for skin wounds. Background Art
[0002] The suture-free patch, also known as the tension-reducing patch, is a tension-reducing device used to be pasted around the skin wound. It is mainly used to reduce the skin tension at the wound and promote the crawling of epidermal cells towards each other. In actual application, it is necessary to first stick the adhesive layer of the tension-reducing device on both sides of the wound. By pulling the tapes on both sides towards each other to tighten the wound, it can replace sutures to help repair the wound. The suture-free patch currently used clinically is usually suitable for neat strip or linear wounds and cannot be used directly on circular wounds. Among chronic wounds, circular wounds are the most common, and auxiliary incisions and sutures are required to accelerate wound healing. Therefore, following the mechanical principles of wound healing, a suture-free patch that is conducive to the healing of circular wounds is designed, which will shorten the wound healing time and reduce scars and patient pain.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0031] Based on this, the utility model provides a suture-free patch for skin wounds, which can tighten wounds that are close to circular in shape and has a good tightening effect.
[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a skin wound suture-free patch, including an elastic layer 1 and a tightening assembly 3. The elastic layer 1 is provided with a circular through hole 2. The tightening assembly 3 includes a plurality of first fixing belts 31, a plurality of active members 32 and a plurality of driven members 33. The plurality of first fixing belts 31 are all installed on the side of the elastic layer 1 away from the circular through hole 2, and are evenly distributed along the circumferential direction around the axial direction of the circular through hole 2, and are arranged one by one in the diameter direction. The active member 32 is installed between any two adjacent first fixing belts 31, and the plurality of driven members 33 are all installed on the side of the elastic layer 1 close to the circular through hole 2, and are arranged one by one in the diameter direction with the plurality of active members 32. They are also configured to be able to gather toward each other in the diameter direction under the drive of the plurality of active members 32.
[0033] It should be noted that the above and below axial directions refer to the bidirectional directions of the central axis defined by the circular through hole 2. Figure 1 The X-axis is shown in FIG. The above and below diameter directions refer to the bidirectional directions of radial lines perpendicular to and intersecting the axis.
[0034] It should be noted that in this embodiment, the example in which the number of first fixing belts 31, the number of active parts 32, and the number of driven parts 33 are all set to six is used for explanation. Of course, in other embodiments, according to actual application requirements, the first fixing belt 31, the active part 32, and the driven part 33 can also be set to four, eight, ten... other even numbers, which are not limited here. Among them, two first fixing belts 31 are symmetrically arranged along the diameter direction as a group, and the six first fixing belts 31 are divided into three groups. Two active parts 32 are symmetrically arranged along the diameter direction as a group, and the six active parts 32 are divided into three groups. Two driven parts 33 are symmetrically arranged along the diameter direction as a group, and the six driven parts 33 are divided into three groups.
[0035] Specifically, when using the device, the circular through hole 2 is first aligned with the wound surface, and the elastic layer 1 can be attached to the skin surface around the wound through the adhesive layer 4. The two active members 32 symmetrically arranged along the diameter direction move toward each other, and drive the two driven members 33 to move toward each other along the diameter direction. Driven by the two driven members 33 arranged along the diameter direction, the skin on both sides of the wound surface in the diameter direction can be driven to move toward each other through the elastic layer 1. Driven by the three groups of active members 32, the three groups of driven members 33 can drive the skin on both sides of the wound surface in three corresponding diameter directions to move toward each other from three different diameter directions.
[0036] The suture-free skin wound patch provided in the present application can drive the skin around the wound to gather towards each other through the elastic layer 1 by means of multiple active parts 32 and multiple driven parts 33. Compared with the related art that tightens the wound from both sides of the wound in parallel directions, the device tightens the wound from the diameter direction of the wound, which has a better tightening effect, facilitates wound repair, and has a good repair effect.
[0037] Optionally, the first fixing belt 31 is configured as an elastic belt.
[0038] With such a configuration, since the human epidermis is mostly curved, when the elastic layer 1 is attached to the skin surface, the first fixing belt 31 can be elastically deformed according to the curvature of the human epidermis, so that the elastic layer 1 can be better attached to the skin surface, thereby making the device applicable to different parts of the human body. In addition, it helps to improve the stability between the elastic layer 1 and the human skin, and it is not easy to get loose.
[0039] In one embodiment of the present application, see Figure 1 and Figure 2 The active member 32 includes a fixing sleeve 321 and a magnet 322. The fixing sleeve 321 is installed between any two adjacent first fixing belts 31, and the magnet 322 is slidably arranged in the fixing sleeve 321. The two magnets 322 arranged along the diameter direction have different magnetic poles.
[0040] In this arrangement, since the two magnets 322 arranged along the diameter direction have different magnetic poles, through the principle of opposite poles attracting each other, the two magnets 322 arranged along the diameter direction move toward each other under the action of magnetic force, and then the two corresponding driven members 33 can move toward each other along the diameter direction. The fixed sleeve 321 is adopted, when the magnet 322 moves, it can guide the magnet 322 to prevent the magnet 322 from being affected by other magnets 322 in the non-diameter direction, so that the magnet 322 can only move along the diameter direction, which helps to improve the movement stability of the magnet 322, and then the tightening effect of the device can be ensured. In addition, the fixed sleeve 321 is provided with openings at both ends, and the magnet 322 passes through the opening at one end of the fixed sleeve 321 away from the driven member 33, which is convenient for disassembly and installation. The fixed sleeve 321 can be fixedly installed on the elastic layer 1 at one end of the fixed sleeve 321 close to the first fixed belt 31 through the first fixed belt 31, which can prevent the fixed sleeve 321 from moving with the magnet 322, and ensure that the magnet 322 can stably move along the diameter direction. In addition, the magnetic field formed by the magnet 322 can be used to perform magnetic therapy on the wound surface to facilitate wound repair.
[0041] In one embodiment of the present application, please refer to Figure 1 and Figure 2 The distance between the end of the magnet 322 away from the driven member 33 and the end of the fixing sleeve 321 close to the driven member 33 is greater than the moving distance of the magnet 322 in the diameter direction.
[0042] With such arrangement, when the magnet 322 moves along the diameter direction, it can be ensured that at least a portion of the magnet 322 is always located in the fixing sleeve 321 , so that the fixing sleeve 321 can always guide the movement of the magnet 322 .
[0043] In one embodiment of the present application, see Figure 1 and Figure 2 The follower 33 includes a limiting sleeve 331 , which is installed on the elastic layer 1 and sleeved on an end of the magnet 322 away from the first fixing belt 31 .
[0044] With this arrangement, the limiting sleeve 331 is opened at one end close to the fixing sleeve 321 , so that the magnet 322 can be limited in the limiting sleeve 331 , making it easier for the magnet 322 to drive the limiting sleeve 331 to move along the diameter direction, thereby helping to improve the structural stability between the magnet 322 and the limiting sleeve 331 .
[0045] In one embodiment of the present application, see Figure 1 and Figure 2 The follower 33 also includes a tip 332, which is connected to an end of the limiting sleeve 331 away from the magnet 322, and is gradually reduced along the diameter direction from an end close to the limiting sleeve 331 toward an end away from the limiting sleeve 331.
[0046] With such arrangement, the tip 332 can drive the elastic layer 1 to be closer to the central axis of the circular through hole 2, thereby achieving a better tightening effect and facilitating wound repair, compared with a case where the tip 332 is not arranged.
[0047] In one embodiment of the present application, please refer to Figure 1 and Figure 2 A slope 333 is formed on the side of the tip 332 facing the elastic layer 1 .
[0048] With such arrangement, when the plurality of tips 332 approach the central axis position of the circular through hole 2, any two adjacent tips 332 can be prevented from contacting each other, causing the skin to be clamped between any two adjacent tips 332, thereby effectively protecting the skin.
[0049] In one embodiment of the present application, see Figure 1 and Figure 2 The driven member 33 further includes a hook 334, and the hook 334 is installed on the limiting sleeve 331. The active member 32 further includes a pull rope 323, and the pull rope 323 is hung between two hooks 334 arranged along the diameter direction.
[0050] In this arrangement, the pull rope 323 can drive the two limit sleeves 331 to move toward each other along the diameter direction through the two hooks 334 arranged along the diameter direction. With the cooperation of the magnet 322, it is helpful to further improve the tightening effect.
[0051] Optionally, the pull rope 323 is configured as an elastic rope.
[0052] In one embodiment of the present application, see Figure 1 and Figure 2 The hook 334 includes a first rod 3341 and a second rod 3342. The first rod 3341 is installed on the limiting sleeve 331. The second rod 3342 is connected to one end of the first rod 3341 away from the limiting sleeve 331 and is bent relative to the first rod 3341 toward the first fixing belt 31.
[0053] In this configuration, the first rod 3341 can drive the limit sleeve 331 to move in the diameter direction with the cooperation of the pull rope 323. The second rod 3342 can prevent the pull rope 323 from coming off the first rod 3341, which helps to improve the structural stability between the pull rope 323 and the hook 334.
[0054] In one embodiment of the present application, please refer to Figure 1 and Figure 2 The tightening assembly 3 further includes a plurality of second fixing belts 34 , and the second fixing belts 34 are installed between any two adjacent active members 32 .
[0055] In this way, the use of multiple second fixing belts 34 can improve the structural stability between the multiple fixing sleeves 321. In addition, the fixing sleeve 321 has and only has one end away from the limiting sleeve 331 connected to the first fixing belt 31, which can prevent the fixing sleeve 321 from being directly connected to the elastic layer 1 and affecting the contraction of the elastic layer 1.
[0056] Optionally, the second fixing belt 34 is configured as an elastic belt.
[0057] One or more embodiments of the present application are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application should be included in the protection scope of the present application.
