Description

Wound care patch

The present invention relates to a wound dressing, in particular to a wound care patch attached to a special part.

Nowadays, there are many kinds of wound dressing products and they are changing day by day. Usually, after wound debridement or surgery, the wound will be sutured. The wound dressing will be selected according to the nature of the wound, and a good healing environment will be provided to block foreign bodies And avoid various bacteria and viruses in the environment from invading the wound and causing infection. However, most of the existing wound dressings are rectangular or frame-shaped. When they are attached to the special parts of the wounded, such as joints, breasts, etc., the edges and corners of the wound dressing are because The local area of the skin adhered to the wound is small, which may cause it to be easily lifted or fall off. In addition, the wounded person cuts the wound dressing in order to meet the needs of attaching to a special part, which in turn causes a waste of materials for the wound dressing. Therefore, the existing wound dressing needs to be improved.

Therefore, the purpose of the present invention is to provide a wound care patch that does not waste dressings and can be closely attached to wounds in special parts.

Therefore, the wound care patch of the present invention includes an absorbent layer, an adhesive layer that has the same shape as the absorbent layer and expands outwards at equal intervals, and a first release layer that is detachably disposed on the adhesive layer Floor.

The absorbent layer includes an inner surface and an outer surface on opposite sides, four arc-shaped sides connected between the inner surface and the outer surface and connected to each other and extending away from each other. Each arc The edge has two end points, defining four auxiliary lines respectively connecting the two end points of the arc-shaped edges. The auxiliary lines respectively surround the arc-shaped edges to define four airfoil areas. The area of at least one airfoil-shaped area in the area is larger than the area of the remaining airfoil-shaped areas. The attachment layer is arranged on the outer surface of the absorption layer. The first release layer and the inner surface of the absorption layer are located on the same side.

The effect of the present invention is that by providing an airfoil area with a larger area than other airfoil areas, it provides differences in the sticking area and the way of sticking, allowing the user to adjust according to the special wound position or the sticking part. The way of sticking, especially by forming the targeted support and covering of the airfoil area with a larger area, enables the airfoil area to be attached to wounds of different shapes and at the same time to match the arcs. The curved design of the side will not cause bending or warping due to the reflexed corners, so it can increase the degree of conformity and stability for attaching to irregularly shaped parts or parts with higher mobility. Sex.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

Referring to Figures 1 and 2, a first embodiment of the wound care patch of the present invention includes an asymmetric petal-shaped absorbent layer 1 and an adhesive layer that has the same shape as the absorbent layer 1 and expands outward at equal intervals 2. A first release layer 3 and a second release layer 4 located on opposite sides of the attachment layer 2 and detachably disposed.

It should be stated first that, in this embodiment, a wound 7 (shown in Figure 6) located in an areola 82 after a traditional or minimally invasive surgery for breast tumor removal is taken as an example for description. In terms of environment, the size of the wound 7 is different due to various breast-related surgeries, or the shape and size of the areola 82 of the user are different. However, this embodiment is not limited to the above-mentioned use environment and method.

The absorbent layer 1 is specifically a foam dressing, which has the characteristics of not sticking easily and can keep the body intact after absorbing the exudate, and includes an inner surface 11 and an outer surface 12 on opposite sides, and four connections The arc-shaped edges 13 between the inner surface 11 and the outer surface 12 are connected to each other and extend away from each other. Wherein, the inner surface 11 is the side that directly contacts the human body during use.

Referring to Fig. 3, each arc-shaped side 13 has two end points 131, defining four auxiliary lines L connecting the two end points 131 of the arc-shaped sides 13 respectively, and the auxiliary lines L are connected to the arc-shaped sides respectively. 13 surrounds and defines four airfoil-shaped regions 15, one of the airfoil-shaped regions 15 has an area larger than that of the remaining airfoil-shaped regions 15. It should be particularly noted here that in this embodiment, the airfoil area 15 with a larger area among the airfoil areas 15 is defined as the characteristic area 151. In the first embodiment, the airfoil areas 15 The number of the characteristic regions 151 of 15 is described by taking one characteristic region 151 as an example, but the number of the characteristic regions 151 of the airfoil regions 15 can also be more than one, and is not limited thereto. The auxiliary lines L surround and define a central area 14 connected between the airfoil areas 15, that is to say, the airfoil areas 15 are connected around the central area 14, so that the central area 14 and The airfoil regions 15 together constitute the entire absorbent layer 1 (shown in FIG. 1), which is approximately in the shape of an asymmetric petal with one of the more prominent petals.

1 and 2, the adhesive layer 2 is disposed on the outer surface 12 of the absorbent layer 1, and includes an adhesive surface 21 connected to the outer surface 12 of the absorbent layer 1, and an adhesive surface 21 located on the opposite side of the adhesive surface 21的水面22。 Waterproof surface 22. The adhesive surface 21 not only covers the outer surface 12 so that the absorbent layer 1 and the adhesive layer 2 are mutually positioned, but also extends to an area other than the absorbent layer 1, that is, can be used to adhere to human skin. The material of the adhesive surface 21 is made of a hypoallergenic pressure sensitive adhesive, which can effectively reduce the allergic reactions that may occur on the human skin. The waterproof surface 22 is made of a polyurethane (PU) material, and is a soft and malleable film, which is particularly suitable for preventing external water from penetrating into the interior. However, the waterproof surface 22 and the adhesive surface 21 are made of materials The above is not restricted. In addition, the waterproof surface 22 and the adhesive surface 21 are of transparent design, allowing the user to directly observe the change after the absorbent layer 1 absorbs the exudate from the wound 7 (shown in FIG. 6) to consider whether it needs to be replaced. One embodiment.

It should be supplemented that the shape and area of the attachment layer 2 are designed to match the absorption layer 1. When the absorption layer 1 is selected by the user according to actual needs, the attachment layer The area size of 2 should also be changed according to the scaling ratio of the overall area of the absorption layer 1. In actual implementation, it is preferable to design in such a way that the diameter of the attachment layer 2 is at least 3 cm larger than the diameter of the absorption layer 1, mainly to allow the attachment layer 2 to have a sufficient attachment area to improve The adhesion between the absorbent layer 1 and the wound 7 (shown in Figure 6), and the adhesion between the adhesive layer 2 and human skin.

Referring to FIGS. 4 and 5 in conjunction with FIG. 1, the first release layer 3 is located on the same side as the inner surface 11 of the absorption layer 1, and the first release layer 3 is used to temporarily protect the inner surface 11 of the absorption layer 1. The adhesive surface 21 with the adhesive layer 2 prevents the first embodiment from being contaminated by foreign matter or bacteria in the external environment before it is used. The first release layer 3 has a first release area 31, a corresponding larger area of the airfoil area 15, and a second release area 32 with a reflex point 321 bent outward. One end of the first release area 31 that is held by the user's hand covers the top of the reflexed portion 321 and is not connected to the reflexed portion 321. The reflexed portion 321 of the second release area is convenient for the user to fix the reflexed portion 321 with one hand to tear off the first release area 31, and can be held when only the second release area 32 is left. Hold the reflexed part 321 to tear off. If there is no design of the reflexed part 321, the user will have difficulty tearing off the second release area 32 because there is no force point, and it is easy to touch the absorbent layer 1 and The adhesive surface 21 of the adhesive layer 2 causes pollution.

It should be supplemented that the first release layer 3 will be directly torn off during actual use, so the adhesive force between the adhesive surface 21 of the attachment layer 2 and the first release layer 3 needs to be smaller than that of the attachment layer 2 The adhesive force of the adhesive surface 21 and the waterproof surface 22 of the adhesive layer 2 is to avoid damaging the adhesive state of the adhesive surface 21 and the waterproof surface 22 when the first release layer 3 is torn off.

The second release layer 4 is a protective film without glue, and is arranged on the waterproof surface 22 of the attachment layer 2, and includes two adjacent reinforcing sheets 41 located in the center, two of each reinforcing sheet 41 The ends are connected to two of the arc-shaped sides 13 respectively. The reinforcing sheets 41 are mirror-symmetrical and are used to strengthen the overall rigidity of the first embodiment, so as to prevent the first embodiment from bending and generating creases due to external force before use. In addition, there is a joint between the reinforcing sheets 41, and the joint is convenient for the user to hold the reinforcing sheets 41 and take the second release layer 4 away from the waterproof surface 22 of the attachment layer 2 in a direction away from each other. .

Refer to Figure 6 in conjunction with Figures 4 and 5 to illustrate the use of the first embodiment. As mentioned above, when describing the first embodiment, it is attached after traditional or minimally invasive surgery for breast tumor removal. Take the wound 7 located at the lower edge of the areola 82 as an example. The user first tears off the first release area 31 of the first release layer 3 in a direction away from the inflection 321 of the second release area 32, and then aligns the central area 14 of the absorbent layer 1 to the corresponding A nipple 81 and the areola 82 of the wing area, and the characteristic area 151 of the wing-shaped area 15 is aligned with the wound 7 part, and the adhesive layer 2 corresponds to the skin area other than the wound 7 part to be pasted Operation, then tear off the second release area 32 of the first release layer 3 to stick the first embodiment, and finally tear the second release layer 4 away from the waterproof surface 22 of the attachment layer 2 Can complete the attaching operation.

In the first embodiment, the wing-shaped regions 15 have a characteristic region 151 to provide the irregularly-shaped wound 7 with the required supporting strength and covering range, so that the wound care patch is not susceptible to external force deformation. Lifting off the wound 7, plus the arc-shaped design of the arc-shaped edges 13 and the arc-guided connection between the end points 131 of the arc-shaped edges 13, can increase the density of the adhesive on the wound 7. The degree of conformity and the reduction of the aforementioned conventional methods. Because the local area of the skin around the wound 7 is too small because the corners and corners are adhered to the skin, it is easy to lift up or fall off.

Refer to FIGS. 7 and 8, which are a second embodiment of the new wound care patch. The difference from the first embodiment shown in FIG. 6 is that the airfoil regions 15 have two characteristic regions 151. The characteristic areas 151 may be located on opposite sides as shown in FIG. 7, or may be adjacent to each other as shown in FIG. 8. It is worth noting that in the preoperative evaluation of traditional or minimally invasive surgery for breast tumor removal, the doctor will select the type of surgery and the position of the surgery according to the physical condition of each patient, which results in the wound of each patient 7 There are various differences in appearance and location. In particular, the second embodiment can be more flexibly applied to the wound 7 with three-dimensional undulations in terms of the sticking area and the way of sticking with one more feature area 151. In addition, the difference in the arrangement of the characteristic areas 151 can not only increase consumer product choices, but also avoid the need to tailor the previously known shapes that are not designed for the shape and size of special parts, or It is the occurrence of an additional increase in the number of attachments to the aforementioned conventional knowledge, which can avoid waste of materials and reduce the burden on users.

It should be supplemented that the new wound care patch can also be applied to joints with high human mobility, such as elbow joints, knee joints, and shoulder joints..., let's take the elbow joint as an example. When the elbow joint is bent, straightened, and rotated internally and externally, the contour of the elbow joint will be deformed to generate a tensile force, which will cause the wound care patch attached to the elbow joint to be affected. The tensile force is correspondingly expanded or twisted and deformed. At this time, the characteristic areas 151 will provide a supporting force to reduce the stretching force caused by the deformation of the wound care patch, and the rest of the airfoil area 15 can ensure adhesion to the elbow joint The relationship is not damaged, and the wound care patch can be firmly attached to the elbow joint and is not easy to fall off and lift off.

In summary, the new wound care patch, through the differential design of the feature area 151 with a larger area in the wing-shaped area 15 of the absorbent layer 1, allows the user to follow the difference in the shape or location of the wound 7. It can be attached, and can provide better support and covering properties for the wound 7 of different shapes, so as to prevent the wound care patch from being deformed by external force and affecting the adhesion relationship with the wound site. In addition, in conjunction with the curved arc design between the arc-shaped edges 13 and the end points 131 of the arc-shaped edges 13, the problem of too small adhesion area can be avoided, and the new wound care patch can be added to the wound. 7 The closeness to the skin surrounding the wound 7. Therefore, it is indeed possible to achieve the purpose of costing a new type.

However, the above are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
