Description

Technical Field

[0001] The utility model belongs to the technical field of dressing patches, and in particular relates to a wound dressing patch. Background Art

[0002] Medical dressings are wound dressings, used to cover sores, wounds, or other lesions. With the in-depth study of the pathophysiology of wound healing, people's understanding of the wound healing process has become increasingly profound, leading to the continuous improvement and development of medical wound dressings.

[0003] According to the survey, there are many problems with ordinary dressings on the market. For example, most of the existing dressings are large in size, and some wounds are large and some are small. Using the dressings on small wounds will cause waste. The dressings are large in size and difficult to attach to some special parts. In addition, the existing dressing materials are soft and collapsed. When the isolation film is torn off, it is easy for the dressings to stick to each other and cause wrinkles, which affects their use and causes waste of dressings. Utility Model Content

[0004] The purpose of the utility model is to provide a wound dressing patch to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical solution of the present invention is as follows: a wound dressing patch, comprising a base layer, a dressing layer is provided in the middle part of the upper surface of the base layer, an isolation film is adhered to the upper surface of the base layer and the dressing layer, a soft wire runs through the interior of the base layer along its length direction, and two dotted holes distributed at equal intervals are provided on the surface of the base layer.

[0006] Preferably, the dressing layer is a PCB-nanosilver hydrogel dressing.

[0007] Preferably, an extension film is provided at one end of the isolation film.

[0008] Preferably, the dotted hole passes through the base layer, the dressing layer and the isolation film.

[0009] Preferably, the two dotted holes are distributed along the width of the base layer, and the dotted holes are distributed parallel to the long side of the base layer.

[0010] Preferably, the two dotted line holes divide the base layer into three parts, and a soft wire runs through each base layer.

[0011] The wound dressing patch of the utility model has the following advantages:

[0012] 1. The present invention punches a dotted hole 4 on the trisection line of the dressing. By tearing it apart along the dotted line, three dressings of different sizes and areas can be obtained. This allows the dressing to be suitable for wounds of different shapes, such as slender and ordinary types. The user can tear off the dressing of the appropriate size as needed, and the remaining dressing can be used next time, without causing waste.

[0013] 2. The utility model can shape the base layer 1 and bend the base layer 1 by setting the soft wire 6, which can effectively prevent the dressing from becoming soft and collapsing, and avoid the phenomenon that when the isolation film 2 is torn off, the base layer 1 collapses and the inner surface sticks together, causing wrinkles and affecting use.

[0014] 3. Through the setting of PCB-nanosilver hydrogel dressing, the dressing can not only promote wound healing, but also effectively prevent and treat wound infection and kill bacteria, solving the problems of existing dressings with relatively single functions, poor ability to promote skin regeneration, and easy to cause wound adhesion.

[0025] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0026] In order to better understand the purpose, structure and function of the present invention, the wound dressing patch of the present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown, the utility model is a wound dressing patch, comprising a base layer 1, with a dressing layer 3 provided in the middle portion of the upper surface of the base layer 1. The dressing layer 3 is a PCB-nanosilver hydrogel dressing. The PCB-nanosilver hydrogel dressing is formed by combining antibacterial nanosilver and zwitterionic hydrogel. It can not only promote wound healing, but also effectively prevent and treat wound infection and kill bacteria. Through a "one-step" reaction, the silver ion solution is reduced to AgNPs while the zwitterionic hydrogel is formed. No additional reducing agent is required. The formed AgNPs are stable in the hydrogel and avoid agglomeration. The antibacterial dressing obtained by this method can effectively inhibit the growth and reproduction of Gram-positive and Gram-negative bacteria. The PCB-nanosilver hydrogel dressing solves the problems of existing dressings with relatively single functions, poor ability to promote skin regeneration, and easy wound adhesion. It has developed an ideal dressing that integrates sterilization, anti-adhesion, and healing promotion.

[0028] A barrier film 2 is adhered to the upper surfaces of the base layer 1 and the dressing layer 3. An extension film 5 is provided at one end of the barrier film 2 to facilitate tearing of the barrier film 2. A soft thread 6 runs through the interior of the base layer 1 along its length, and two equally spaced dotted holes 4 are provided on its surface. These holes 4 penetrate the base layer 1, the dressing layer 3, and the barrier film 2. The two dotted holes 4 run along the width of the base layer 1 and are parallel to the long sides of the base layer 1. By punching the dotted holes 4 at the trisection line of the dressing, three dressings of different sizes and areas can be obtained by tearing along the dotted lines. This allows the dressing to accommodate wounds of varying shapes, from slender to regular. The user can tear off the dressing of the appropriate size as needed, and the remaining dressing can be reused next time, eliminating waste. The two dotted holes 4 divide the base layer 1 into three parts, and each base layer 1 is penetrated by a soft wire 6. The base layer 1 is the material of the existing dressing patch, which will not be elaborated here. Through the setting of the soft wire 6, the base layer 1 can be shaped and the base layer 1 can also be bent, which can effectively prevent the dressing patch from becoming soft and collapsing, and avoid the phenomenon that when the isolation film 2 is torn off, the base layer 1 collapses and the inner surface sticks together, causing wrinkles and affecting use.

[0029] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
