Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a band-aid. Background Technology

[0002] For example, joints such as elbows and knees often develop wounds due to bumps and scrapes. If the injury is minor, the injured person often covers the wound with a band-aid to prevent it from being exposed to air or coming into contact with external objects and becoming infected. However, because joints such as elbows and knees are frequently in motion, commercially available band-aids often cannot cover joint wounds well. Joint movement can cause the band-aid to loosen and fall off, resulting in the band-aid failing to protect the wound at the joint due to joint movement. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terms "first," "second," and "one end," etc., used in the specification and claims of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, products, or devices.

[0025] See Figure 1A bandage 10 provided in this embodiment of the present invention includes: an adhesive layer 12, an medicated layer 14, and a stretchable layer 16. The adhesive layer 12 has a main adhesive region 122, a first adhesive arm 124, and a second adhesive arm 126. The first adhesive arm 124 is connected to one side of the adhesive region 122, and the second adhesive arm 126 is connected to the side of the adhesive region 122 away from the first adhesive arm 124. The medicated layer 14 is attached to the main adhesive region 122. The stretchable layer 16 connects to the main adhesive region 122, and the first adhesive arm 124 and the second adhesive arm 126 are respectively connected to the main adhesive region 122 through the stretchable layer 16.

[0026] When a user uses the adhesive bandage 10 to cover a joint wound, such as an elbow wound, the user first relaxes their arm vertically and then attaches either the first adhesive arm 124 or the second adhesive arm 126 to the user's upper arm near the wound. Subsequently, the other adhesive arm of either the first adhesive arm 124 or the second adhesive arm 126 is attached to the user's forearm near the wound. At this time, the stretchable layer 16 is not stretched and is therefore in a naturally extended state without stress, and the medicated layer 14 is attached to the wound. When the user moves the elbow joint with the wound, for example, by rotating the forearm relative to the elbow joint, the stretchable layer 16 is stretched by the user's forearm and upper arm, thus ensuring that the first adhesive arm 124 and the second adhesive arm 126 are not pulled off due to the user's arm movement; and at this time, the medicated layer 14 remains attached to the wound. Therefore, by providing the stretchable layer 16, the adhesive bandage 10 ensures that the movement of the user's arm will not cause the adhesive bandage 10 to fall off the user's arm, and always ensures that the medicated layer 14 is well attached to the wound at the user's elbow joint, thereby protecting the wound.

[0027] Specifically, the first adhesive arm 124 and the second adhesive arm 126 should be adhered to the skin of the user's upper arm and forearm, rather than to the skin of the elbow joint. The skin of the elbow joint should correspond to the medicated layer 14 and the elastic layer 16, thereby ensuring the effectiveness of the adhesive bandage 10. The elastic layer 16 is, for example, an elastic material such as diene elastic fiber or composite elastic fiber.

[0028] Further, see Figure 2The adhesive layer 12 further includes a secondary adhesive region 128. The stretchable layer 16 surrounds and connects to the primary adhesive region 122, and the secondary adhesive region 128 surrounds and connects to the stretchable layer 16. The first adhesive arm 124 and the second adhesive arm 126 are respectively connected to the stretchable layer 16 through the secondary adhesive region 128. The secondary adhesive region 128 can adhere to the skin around the user's elbow joint in multiple directions, thereby further improving the protective effect of the bandage 10 on wounds at the elbow joint.

[0029] Furthermore, see Figure 2 or Figure 4 The stretchable layer 16 is annular in shape. Specifically, the stretchable layer 16 may be, for example, circular or elliptical, and the annular shape allows the stretchable layer 16 to better withstand tensile forces in multiple directions.

[0030] Further, see Figure 3 The adhesive layer 12 further includes a first auxiliary adhesive arm 121 and a second auxiliary adhesive arm 123. The first auxiliary adhesive arm 121 is connected to one side of the stretchable layer 16. The second auxiliary adhesive arm 123 is connected to the side of the stretchable layer 16 away from the first auxiliary adhesive arm 121. The first auxiliary adhesive arm 121 and the second auxiliary adhesive arm 123 are arranged along a first direction, and the first adhesive arm 124 and the second adhesive arm 126 are arranged along a second direction, intersecting the first and second directions. For example, the first auxiliary adhesive arm 121 and the second auxiliary adhesive arm 123 are connected to the left and right sides of the user's elbow joint from the user's perspective, thereby further increasing the adhesion area between the adhesive bandage 10 and the skin around the user's elbow joint, thus further improving the protective effect of the adhesive bandage 10. Specifically, the first direction is, for example,... Figure 3 The x-direction shown or the opposite direction of the x-direction, the second direction being, for example, Figure 3 The y-direction shown or the opposite direction of the y-direction, the first direction and the second direction, for example, form any angle within the interval [80°, 100°], such as being perpendicular to each other.

[0031] Furthermore, see Figure 3 The stretchable layer 16 surrounds and connects to the main adhesive region 122. Thus, the stretchable layer 16 can withstand tensile forces in multiple directions, thereby better protecting the user's joint wounds with the adhesive bandage 10.

[0032] Furthermore, see Figure 4The adhesive layer 12 further includes a secondary adhesive region 128. The secondary adhesive region 128 surrounds and connects to the stretchable layer 16, and the first auxiliary adhesive arm 121 and the second auxiliary adhesive arm 123 are connected to the stretchable layer 16 through the secondary adhesive region 128. By combining the first adhesive arm 124, the second adhesive arm 126, the first auxiliary adhesive arm 121, the second auxiliary adhesive arm 123, and the secondary adhesive region 128, the bandage 10 can, for example... Figure 4 The adhesive bandage 10 adheres to the skin around the user's joints at any angle in the xy plane, thereby improving the protective effect of the bandage 10 on wounds at the user's joints.

[0033] Furthermore, see Figure 4 The length L124 of the first adhesive arm 124 in the second direction y is greater than the length L121 of the first auxiliary adhesive arm 121 in the first direction x and the length L123 of the second auxiliary adhesive arm 123 in the first direction x; the length L126 of the second adhesive arm 126 in the second direction y is greater than the length L121 of the first auxiliary adhesive arm 121 in the first direction x and the length L123 of the second auxiliary adhesive arm 123 in the first direction. Given that the lengths L124 and L126 of the first adhesive arm 124 and the second adhesive arm 126 along the second direction y are determined, considering that the first auxiliary adhesive arm 121 and the second auxiliary adhesive arm 123 are adhered to, for example, both sides of the elbow joint from the user's perspective, the lengths L121 of the first auxiliary adhesive arm 121 and L123 of the second auxiliary adhesive arm 123 along the first direction x can be set relatively short, thereby saving material without affecting the effectiveness of the first auxiliary adhesive arm 121 and the second auxiliary adhesive arm 123.

[0034] In addition, see Figure 5 The adhesive layer 12 has a plurality of ventilating holes 125. The user's skin, which is adhered to the adhesive layer 12, can breathe through the plurality of ventilating holes 125.

[0035] Further, see Figure 6 The adhesive bandage 10 also includes a protective layer 18. The protective layer 18 is disposed on the stretchable layer 16, surrounding and connecting the medicated layer 14. The main adhesive region 122 and the medicated layer 14 are stacked along a third direction (z-axis), the stretchable layer 16 and the protective layer 18 are stacked along the third direction (z-axis), and the medicated layer 14 and the protective layer 18 are located on the same side of the adhesive layer 12.

[0036] The protective layer 18 is used to separate the medicine layer 14 from the outside air. The protective layer 18 can be made of materials such as cotton or non-woven fabric, so that it has a certain water absorption effect or a certain filtration effect.

[0037] Furthermore, see Figure 6 The protective layer 18 has a protrusion 182 in the third direction z. The protrusion 182 protrudes from the drug layer 14 in the third direction z. The protrusion 182, as... Figure 6 As shown, the protrusion 182 is higher than the upper surface of the medicated layer 14 on the third direction z, so that when the adhesive bandage 10 is attached to the user's skin, the protrusion 182 abuts against the user's skin, thereby better blocking the wound of the user's joint from the outside atmosphere.

[0038] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of this utility model. Provided that the technical features do not conflict, are fixed and do not contradict each other, and do not violate the utility model's purpose, the technical solutions of each embodiment can be arbitrarily combined and used.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
