Description

Technical Field

[0001] This utility model relates to the field of trauma medical device technology, and in particular to a composite sandwich easy-tear wound dressing. Background Technology

[0002] Band-aids are a common medical product used for wound care. They are typically used to cover and protect wounds, preventing them from being invaded by external bacteria and contaminants such as dust, while providing a relatively clean environment conducive to healing.

[0003] In daily life, people encounter various small wounds of different parts and types, such as abrasions on fingers, arms, heels, sides of feet and toes. These parts have different shapes, and the size and shape of the bandages required are also different. Traditional bandages are often monolithic and cannot adapt well to these diverse wound sites. At this time, composite layered easy-tear bandages are needed.

[0004] Currently available multi-layer easy-tear adhesive bandages mainly consist of a base layer, a functional layer, pressure-sensitive adhesive, a release layer, and an auxiliary layer. To use them, the auxiliary layer is first peeled off, the functional layer is aligned with the wound, and then the release layer is applied to the skin to secure the device. However, when tearing apart multi-layer adhesive bandages, adjacent bandages can easily stick together too tightly. To address this issue, existing technologies often employ pre-cut or weakened line designs to ensure easy separation. However, in actual use, this design often results in loose connections between multiple bandages during transportation and handling, causing them to separate within the packaging before use, reducing the device's practicality and failing to meet user needs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular, easy-tear adhesive bandage, which aims to improve the problem of loose connection between multiple adhesive bandages in the existing modular, easy-tear adhesive bandage.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a composite layered easy-tear adhesive bandage, including a sheath layer, a fixing strip fixedly connected to the rear side of the sheath layer, an inner cavity opened inside the fixing strip, springs fixedly connected to the left and right sides of the top of the inner cavity, the bottom ends of the two springs fixedly connected to the same connecting rod, a connecting post fixedly connected to the upper middle part of the connecting rod, the upper end of the connecting post penetrating the fixing strip, a base fixedly connected to the left and right ends of the connecting rod, a pin fixedly connected to the top of the base, through holes opened on the left and right sides of the rear end of the inner cavity, fixing pieces fixedly connected to the left and right sides of the front wall of the sheath layer, insertion holes opened on the top of the two fixing pieces, and a waterproof mechanism provided inside the sheath layer, the waterproof mechanism being used to facilitate the breathability and waterproofing of the adhesive bandage.

[0007] As a further description of the above technical solution:

[0008] The waterproofing mechanism includes a base layer, which is disposed inside the sheath layer. A vent hole is provided at the top center of the base layer. A waterproof layer is fixedly connected to the top of the base layer. A square hole is provided at the top center of the waterproof layer. A waterproof sheet is rotatably connected to the left end of the square hole. A connecting piece is fixedly connected to the right center of the waterproof sheet. A second adhesive layer is fixedly connected to the bottom of the connecting piece.

[0009] As a further description of the above technical solution:

[0010] A rubber ball is fixedly connected to the top of the connecting column, and easy-tear strips are provided on both the left and right sides of the sheath layer.

[0011] As a further description of the above technical solution:

[0012] The base layer is fixedly connected to the left and right sides of its bottom, and an anti-sticking layer is provided at the bottom of both first adhesive layers.

[0013] As a further description of the above technical solution:

[0014] H-shaped plates are slidably connected to the left and right sides of the base layer. A fixing rod is fixedly connected to one adjacent end of the inner side of each of the two H-shaped plates. A connecting strip is fixedly connected to the front and back of one side of each of the two anti-adhesive layers. Multiple connecting strips are fixedly connected to the corresponding fixing rods.

[0015] As a further description of the above technical solution:

[0016] The size of the base layer matches the size of the waterproof layer, and the size of both first adhesive layers matches the size of the base layer.

[0017] As a further description of the above technical solution:

[0018] An antibacterial layer is fixedly connected to the lower middle part of the base layer, and a sponge layer is fixedly connected to the bottom of the antibacterial layer.

[0019] As a further description of the above technical solution:

[0020] A medical layer is fixedly connected to the bottom of the sponge layer, and the size of the medical layer matches the size of the sponge layer.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the connecting column drives the connecting rod to move downward. At this time, the connecting rod will drive the bases at both ends to move downward, and the bases at both ends will drive the pin to move downward. The movement of the pin releases its limiting effect on the fixing piece. At this time, the sheath layer can be moved to remove a single bandage. Furthermore, by pulling the connecting rod with a spring, the pin will always be inside the insertion hole, keeping it tightly connected when the bandage is not needed. This improves the practicality of the device and can meet the needs of users.

[0023] 2. In this utility model, pulling the connecting piece causes the second adhesive layer to move upward, which opens the square hole. At this time, air can enter the wound area through the vent hole at the top of the base layer, preventing bacteria from growing in the wound area due to poor air circulation. Furthermore, pulling the connecting piece to adhere the second adhesive layer to the waterproof layer improves the waterproofness of the bandage and enhances the safety of the device.

A fixing strip 3 is fixedly connected to the rear side of the sheath layer 1, facilitating the fixation of two adhesive bandages. An inner cavity 4 is formed inside the fixing strip 3. Springs 9 are fixedly connected to the left and right sides of the top of the inner cavity 4. The bottom ends of the two springs 9 are fixedly connected to the same connecting rod 6. The springs 9 pull the connecting rod 6, ensuring that the pin 8 remains inside the insertion hole 12. A connecting post 5 is fixedly connected to the upper middle part of the connecting rod 6. The upper end of the connecting post 5 passes through the fixing strip 3, and the connecting post 5 is used to move the connecting rod 6. The left and right ends of the connecting rod 6 are fixedly connected to... The device includes a base 7, with a pin 8 fixedly connected to the top of the base 7 for mounting the pin 8. Through holes 10 are provided on both the left and right sides of the rear end of the inner cavity 4. Fixing plates 11 are fixedly connected to both the left and right sides of the front wall of the sheath layer 1. Insertion holes 12 are provided on the top of each fixing plate 11, providing an insertion position for the pin 8. A waterproof mechanism 2 is provided inside the sheath layer 1, facilitating ventilation and waterproofing of the bandage. A rubber ball 13 is fixedly connected to the top of the connecting post 5, allowing for easy pressing of the connecting post 5. Easy-tear strips 14 are provided on both the left and right sides of the sheath layer 1, making it easy to tear the sheath layer 1.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The waterproofing mechanism 2 includes a base layer 201, which is disposed inside the sheath layer 1. A vent 202 is provided at the top center of the base layer 201 to supply air to the wound. A waterproof layer 203 is fixedly connected to the top of the base layer 201 to prevent water from entering the wound. A square hole 204 is provided at the top center of the waterproof layer 203, and a waterproof sheet 205 is rotatably connected to the left end of the square hole 204 to seal the square hole 204. A connecting piece 206 is fixedly connected to the middle right side of the waterproof sheet 205. A second adhesive layer 207 is fixedly connected to the bottom of the connecting piece 206. The second adhesive layer 207 can fix the connecting piece 206, thereby fixing the waterproof sheet 205. A first adhesive layer 15 is fixedly connected to the bottom left and right sides of the base layer 201. An anti-adhesive layer 16 is provided at the bottom of both first adhesive layers 15. The first adhesive layer 15 is used to fix the bandage. The anti-adhesive layer 16 provides protection for the first adhesive layer 15 when the bandage is not needed.

[0036] Reference Figure 4 and Figure 6 H-shaped plates 20 are slidably connected to the left and right sides of the base layer 201. Fixing rods 21 are fixedly connected to the adjacent inner ends of the two H-shaped plates 20. Connecting strips 22 are fixedly connected to the front and back of one side of the two anti-adhesive layers 16. Multiple connecting strips 22 are fixedly connected to the corresponding fixing rods 21. When using, first apply the bandage to the skin, then pull the H-shaped plates 20. The H-shaped plates 20 move the connecting strips 22 through the fixing rods 21, which can peel off the anti-adhesive layers 16. The size of the base layer 201 matches the size of the waterproof layer 203, so that the waterproof layer 203 can provide complete protection. The size of the two first adhesive layers 15 matches the size of the base layer 201, so that the first adhesive layers 15 can fix the base layer 201 tightly.

[0037] Reference Figure 7 An antibacterial layer 17 is fixedly connected to the lower center of the base layer 201. The antibacterial layer 17 prevents bacteria from entering the wound through the vent 202. A sponge layer 18 is fixedly connected to the bottom of the antibacterial layer 17. The sponge layer 18 can absorb tissue fluid exuded from the wound. A medical layer 19 is fixedly connected to the bottom of the sponge layer 18. The medical layer 19 can help the wound heal faster and provide disinfection. The size of the medical layer 19 matches the size of the sponge layer 18, making the area of ​​the medical layer 19 larger and providing a better recovery environment for the wound.

[0038] Working principle: When a bandage is needed, first press the rubber ball 13. Pressing the rubber ball 13 will cause the connecting post 5 to move downward. At this time, the connecting rod 6 will move downward, and the connecting rod 6 will cause the bases 7 at both ends to move downward. When the bases 7 at both ends move downward, they will cause the pin 8 to move downward. When the pin 8 moves, it will disengage from the insertion hole 12, thus releasing its limiting effect on the fixing piece 11. At this time, the sheath layer 1 can be moved to remove a single bandage. The sheath layer 1 can be easily torn open by the easy-tear strip 14. At the same time, when the bandage is not needed, the spring 9 pulls the connecting rod 6, so that the pin 8 is always inside the insertion hole 12, and multiple bandages are not easy to fall apart.

[0039] Furthermore, when waterproofing is not required during the use of the bandage, pulling the connecting piece 206 will cause it to move upwards, disengaging the second adhesive layer 207 from the waterproof layer 203. This opens the square hole 204, allowing air to enter the wound through the vent hole 202 at the top of the base layer 201, preventing bacteria growth due to poor air circulation. When waterproofing is required, pulling the connecting piece 206 will ensure a tight bond between the second adhesive layer 207 and the waterproof layer 203, thus achieving the waterproof function of the bandage.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
