Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a self-adhesive local wound pressure device. Background Technology

[0002] Currently, when surgical patients require pressure bandaging, the most common method is to use a full-body bandage, with gauze placed inside the bandage for added pressure. This method applies even pressure to the wound area by wrapping the bandage around it, and the gauze absorbs exudate to promote hemostasis and healing. Traditional procedures rely on the experience of medical staff to adjust the tightness, which achieves basic pressure, but the bandage material is stiff and has limited breathability. Long-term use can easily lead to pressure sores or obstructed blood circulation.

[0003] In existing technologies, compression devices based on improved bandages are gradually incorporating elastic materials. For example, adhesive patches are used to fix the edges of the wound, and elastic bands are combined to provide directional traction. Some products use breathable fabric bases or zoned pressure adjustment structures to reduce the risk of skin damage and improve adaptability. Such solutions improve the comfort and fixation effect of traditional bandages to a certain extent through material optimization and local pressure control.

[0004] However, existing technologies still have technical problems in practical use, such as the single traction force and cumbersome pressure adjustment. Conventional wound pressure devices rely on a single elastic band structure, which makes it difficult to dynamically adjust the direction, quantity and traction force according to the wound shape. This can easily lead to uneven pressure distribution in irregular wounds, affecting the patient's physical activity and resulting in low comfort. Utility Model Content

[0005] Therefore, this utility model provides a self-adhesive local wound pressure device to solve the problems of single traction force and cumbersome pressure adjustment in existing wound pressure devices.

[0006] To achieve the above objectives, the embodiments of this utility model provide the following technical solutions:

[0007] A self-adhesive local wound pressure device includes at least two patch base plates. One side of each of the two patch base plates is attached to the skin on both sides of the wound by means of an adhesive surface. The other side of each of the two patch base plates is provided with a transparent hook surface.

[0008] Both of the patch base plates are connected to a tension band structure via a transparent hook surface. The tension band structure consists of multiple parallel elastic bands. Any adjacent elastic bands are connected by a connecting piece. One side of each elastic band is connected to any part of the transparent hook surface on the patch base plate via a plush surface.

[0009] The connecting piece has teeth evenly distributed along its length, and any of the connecting pieces can be split in half along the teeth to adjust the width and number of the tension band structure.

[0010] In a preferred embodiment of this utility model, the length direction of the connecting piece is consistent with the length direction of the corresponding two elastic bands.

[0011] As a preferred embodiment of this utility model, the elastic band has an internal interlayer, and a plurality of equidistantly distributed energy storage ribs are provided in the interlayer of the elastic band. The length direction of the energy storage ribs is perpendicular to the length direction of the elastic band. Both ends of the energy storage ribs are provided with connecting lines, and one end of the connecting line passes through the elastic band and is fixedly connected to the corresponding connecting piece.

[0012] As a preferred embodiment of this utility model, the middle part of the energy storage rib has a V-shaped structure. When the elastic band is not under force, there is a gap between the two ends of the energy storage rib and the two corresponding connecting pieces. When the elastic band is subjected to tension along its length, the energy storage rib deforms to reduce the gap between its two ends and the two corresponding connecting pieces.

[0013] In another embodiment of the present invention, when the elastic band is not under stress, the distance between the end of the energy storage rib and the corresponding connecting piece is the same as the length of the connecting line.

[0014] The embodiments of this utility model have the following advantages:

[0015] (1) The present invention provides a patch base plate that can be cut according to the size and shape of the wound and is attached to both sides of the wound. The two patch base plates are connected by a tension band structure with elasticity. The tension band structure provides appropriate elasticity, so that the patch base plates located on both sides of the wound apply pressure to the skin of the attachment area that tends to close the wound.

[0016] (2) The tension band structure is designed as a modular multi-elastic band structure, which makes the overall width and number of tension band structures adjustable, making it easy to adapt to various shapes of patch base plates. In addition, multiple elastic bands can form multiple tightening directions of pressure between two patch base plates, making it easy to adjust the tightness of each tension band and ensure that the local pressure is reasonable.

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1-3As shown, this embodiment provides a self-adhesive local wound pressure device, including at least two patch base plates 1. One side of each patch base plate 1 is attached to the skin on both sides of the wound via an attachment surface 101. The other side of each patch base plate 1 is provided with a transparent hook surface 102. Each patch base plate 1 is connected to a tension band structure via the transparent hook surface 102. The tension band structure is composed of multiple parallel elastic bands 2. One side of each elastic band 2 is connected to any part of the transparent hook surface 102 on the patch base plate 1 via a plush surface 201.

[0028] Specifically, the patch base plate 1, cut according to the size and shape of the wound, is attached to both sides of the wound. After cleaning the attachment surface 101 of the patch base plate 1, it is attached to the healthy skin surface on both sides of the wound. The visibility characteristics of the transparent hook surface 102 ensure accurate alignment. The elastic band 2 is first attached to one patch base plate 1, and an appropriate tension is applied to the elastic band 2 before it is attached to another patch base plate 1. The elastic tension is released by multiple elastic bands 2, so that the patch base plates 1 located on both sides of the wound apply pressure to the skin of the attachment area that tends to close the wound.

[0029] In this configuration, any adjacent elastic bands 2 are connected by a connecting piece 3; the connecting piece 3 has teeth 4 evenly distributed along its length, and any connecting piece 3 can be split in half along the teeth 4 to adjust the width and number of tension bands.

[0030] The length direction of the connecting piece 3 is consistent with the length direction of the two corresponding elastic bands 2.

[0031] The width and number of tension bands can be adjusted according to the size and shape of the patch base plate 1. Specifically, the connecting piece 3 is torn along the toothed line 4 at the corresponding width position on the tension band structure according to the required elastic band width, so that the connecting piece 3 is torn into two halves until the tension band structure is split into the required number of elastic bands 2. By bonding the plush surface 201 on each elastic band 2 to any area of ​​the transparent hook surface 102, a multi-directional traction layout is formed to avoid local pressure concentration.

[0032] The elastic band 2 has an internal interlayer, and multiple equidistant energy storage ribs 202 are provided in the interlayer of the elastic band 2. The length direction of the energy storage ribs 202 is perpendicular to the length direction of the elastic band 2. Both ends of the energy storage ribs 202 are provided with connecting lines 203. One end of the connecting line 203 passes through the elastic band 2 and is fixedly connected to the corresponding connecting piece 3.

[0033] The middle part of the energy storage rib 202 has a V-shaped structure. When the elastic band 2 is not under stress, there is a gap between the two ends of the energy storage rib 202 and the two corresponding connecting pieces 3. When the elastic band 2 is subjected to tension along its length, the energy storage rib 202 deforms to reduce the gap between its two ends and the two corresponding connecting pieces 3.

[0034] When the elastic band 2 is not under stress, the distance between the end of the energy storage rib 202 and the corresponding connecting piece 3 is the same as the length of the connecting line 203.

[0035] Specifically, since the length of the elastic band 2 changes during the stretching process, while the length of the connecting piece 3 is fixed, as the elastic band 2 becomes longer under tension, the distance between the two ends of the connecting points of each connecting line 203 continuously increases. However, the deformation of the energy storage rib 202 can always keep the distance between the two ends of the connecting points of the connecting line 203 consistent, so that the connecting piece with a fixed length can always fully connect the elastic band 2 with a changing length.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
