[0036] Figure 1 and Figure 2 The present invention illustrates a wound elastic dressing device 10 in some embodiments, which is used to apply pressure to a wound surface, which refers to a surface with trauma in the medical field, and the wound elastic dressing device 10 is used to treat the wound surface.

[0037] like Figure 1 and Figure 2 As shown, the wound elastic dressing device 10 includes a pressure mesh 1, a fixing component 2, and a dressing component 3. The fixing component 2 is disposed on the pressure mesh 1, and the dressing component 3 is disposed on the pressure mesh 1.

[0038] It should be noted that the pressure gauze 1 can be made of medical gauze from the existing medical field, and can be configured to include several layers of gauze, which are fixed together by sewing; thereby enhancing the overall tensile strength of the gauze while maintaining breathability. The pressure gauze can also be configured to include a long piece of gauze, which is folded in multiple sections and then sewn together at the edges. The fixing component 2 is used to bind the pressure gauze 1 to the patient's limb or torso, thereby applying force to the dressing component 3 through the pressure gauze 1, so that the dressing component 3 can be applied to the wound surface accordingly.

[0039] Understandably, different medical purposes or different treatment targets of wound treatment medications can be set on the dressing component 3, so that the wound elastic dressing device 10 can be applied to various types of wounds, thereby improving the universality of the product for different types of wounds.

[0040] like Figures 1 to 6 As shown, the dressing mesh 1 has a wound surface 11 and a non-wound surface 12. The fixing component 2 includes several binding structures 21, each binding structure 21 including an elastic band 211, a first hook and loop fastener 212, and a second hook and loop fastener 213. The elastic band 211 is connected to the dressing mesh 1, extends away from the dressing mesh 1, and is connected to the first hook and loop fastener 212. The second hook and loop fastener 213 is disposed on the non-wound surface 12. The dressing component 3 is disposed on the wound surface 11.

[0041] After the elastic band 211 wraps around the predetermined position, it causes the first hook and loop fastener 212 to adhere to the second hook and loop fastener 213, so that each binding structure 21 holds the dressing assembly 3 and applies it to the wound through the dressing mesh 1.

[0042] Understandably, the partitioned design of the wound surface 11 and the non-wound surface 12 allows the dressing component 3 to accurately cover the wound area, while the non-wound surface 12 is provided with a fixed support point through the second Velcro 213 to avoid direct contact with the wound and cause secondary damage.

[0043] The positions of each elastic stretch band 211 on the pressing mesh 1 can be flexibly set. For example, each elastic stretch band 211 can be configured to be radially distributed on the outer periphery of the pressing mesh 1; each elastic stretch band 211 can also be configured to be parallel to each other.

[0044] The dressing component 3 can be configured to adhere to the wound surface 11 via a medical adhesive layer or mesh pressing method, and its interior can be impregnated with antibacterial agents, healing factors, or absorbent hydrogels. When the pressure mesh 1 applies vertical pressure to the dressing component 3, the dressing component 3 reduces wound exudation through physical compression on the one hand, and regulates the wound microenvironment through sustained drug release on the other hand.

[0045] It should be noted that the elastic band 211 can be made of various elastic materials in the prior art; the elastic band 211 is preferably made of medical-grade elastic materials in the prior art. One of the first hook and loop fastener 212 and the second hook and loop fastener 213 is configured as a loop side, and the other of the first hook and loop fastener 212 and the second hook and loop fastener 213 is configured as a hook side, and the loop side and the hook side can be connected.

[0046] like Figure 2 and Figure 6 As shown, in some embodiments of the wound elastic dressing device 10, each elastic elastic band 211 includes a first elastic band 2111 and a second elastic band 2112. The first elastic band 2111 and the second elastic band 2112 are symmetrically arranged on the dressing mesh 1. The first Velcro 212 is disposed at the end of the first elastic band 2111, and the second Velcro 213 is disposed on the second elastic band 2112.

[0047] The first elastic band 2111 and the second elastic band 2112 are used to wrap around a predetermined position so that the first hook and loop fastener 212 is attached to the second hook and loop fastener 213.

[0048] Understandably, the first elastic band 2111 and the second elastic band 2112 are symmetrically arranged on both sides of the edge of the dressing mesh 1, forming a bidirectional tension structure. This design ensures that the dressing mesh 1 is subjected to uniform force during the binding process, avoiding mesh shifting or wrinkling caused by unilateral tension, and ensuring that the dressing assembly 3 fully covers the wound.

[0049] It should be noted that when the first elastic band 2111 and the second elastic band 2112 are wrapped around the limb, the first elastic band 2111 and the second elastic band 2112 generate synergistic tension through elastic deformation, so that the Velcro is glued together to form a closed loop system, which adapts to changes in limb circumference while maintaining a stable pressure value.

[0050] like Figure 2 and Figure 6 As shown, in some embodiments of the wound elastic dressing device 10, each binding structure 21 includes a plurality of second hook and loop fasteners 213, and each second hook and loop fastener 213 is arranged at intervals along the length extension direction of the second elastic band 2112.

[0051] Understandably, multiple second hook and loop fasteners 213 are arranged at intervals along the length of the second elastic band 2112 to form continuously adjustable adhesive points. By selecting different positions of the second hook and loop fasteners 213 to bond with the first hook and loop fasteners 212, the tightness of the elastic band 211 can be adjusted in stages to match the pressure requirements of different stages of wound healing (such as low pressure in the acute phase and moderate pressure in the proliferative phase).

[0052] like Figure 2 and Figure 6 As shown, in some embodiments of the wound elastic dressing device 10, each elastic stretch band 211 includes a positioning ring 2113, which is disposed at the end of the second stretch band 2112 and is for the first stretch band 2111 to pass through.

[0053] Understandably, the positioning ring 2113 is fixed to the end of the second telescopic band 2112, and the inner diameter of the positioning ring 2113 is slightly larger than the width of the first telescopic band 2111. After the first telescopic band 2111 is threaded through the positioning ring 2113, its extension path is physically limited to prevent the band from twisting or tangling during binding, thereby improving the ease of operation and enhancing the product's application effect on the wound.

[0054] In some embodiments of the wound elastic dressing device 10, a soft dressing surface is provided on the elastic stretch band 211, and the orientation of the soft dressing surface is the same as that of the wound surface 11.

[0055] Understandably, the soft dressing can be made of medical-grade silicone or skin-friendly non-woven fabric and fixed to the side of the elastic band 211 that contacts the patient's skin. The soft dressing should face the wound surface 11 to ensure that it remains in contact with the limb surface during the binding process, preventing the hard edges of the elastic band 211 or the sutures from directly rubbing against the skin.

[0056] It should be noted that the flexibility of the soft dressing can disperse the local pressure of the elastic band 211 on the skin and prevent blood circulation obstruction caused by prolonged binding; at the same time, its surface micro-texture structure increases the static friction with the skin and reduces the overall displacement of the binding structure 21 caused by limb movement, thereby maintaining the accurate positioning of the dressing component 3.

[0057] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the wound elastic dressing device 10, each binding structure 21 is arranged one by one along the length extension direction or width extension direction of the dressing mesh 1, and the extension directions of each two adjacent elastic stretch bands 211 are opposite.

[0058] Understandably, the reverse-extending elastic bands 211 generate complementary vector forces when bound: when the limb deforms in a certain direction (such as muscle contraction), the reverse-arranged elastic bands 211 offset the sudden change in unilateral tension through elastic deformation, so that the overall force of the dressing mesh 1 tends to be balanced, avoiding the problem of dressing edge lifting or uneven pressure caused by excessive unidirectional tension.

[0059] like Figure 3 and Figure 5As shown, in some embodiments of the wound elastic dressing device 10, the dressing assembly 3 includes a gauze block 31, the surface of which is provided with an adhesive layer 32, and the gauze block 31 is adhered to the wound surface 11 through the adhesive layer 32.

[0060] Understandably, the gauze pad 31 is flexibly bonded to the wound surface 11 by the adhesive layer 32, allowing the pressure applied by the pressure gauze 1 to be evenly transmitted to the entire surface of the gauze pad 31. When limb movement causes local deformation of the pressure gauze 1, the adhesive layer 32 adjusts the stress distribution through micro-slippage, avoiding damage to newly formed granulation tissue caused by shear force due to rigid fixation.

[0061] Furthermore, the adhesive layer 32 can be configured as a medical-grade pressure-sensitive adhesive.

[0062] In some embodiments of the wound elastic dressing device 10, the dressing assembly 3 includes a plurality of gauze blocks 31, each of which is provided with an adhesive layer 32. The effective pressure area of ​​each gauze block 31 is different, and any gauze block 31 can be adhered to the wound surface 11 by the adhesive layer 32.

[0063] Understandably, the application area of ​​multiple gauze pads 31 can be flexibly set, but it is necessary to ensure that at least some gauze pads 31 can be used for wounds of different sizes. In actual use, since each gauze pad 31 is provided with an adhesive layer 32, medical staff can combine multiple gauze pads according to the contour of the wound, thereby avoiding the application of medication through the gauze pads 31 onto skin that does not require treatment, and thus avoiding damage to normal skin.

[0064] In some embodiments of the wound elastic dressing device 10, the pressure mesh 1 and the elastic stretch band 211 are fused together.

[0065] Understandably, the fusion bonding allows the pressure mesh 1 and the elastic stretch band 211 to form an integrated structure, eliminating stress concentration caused by traditional sewing or gluing and improving user comfort.

[0066] In some embodiments of the wound elastic dressing device 10, the dressing mesh 1 has an installation channel, and the elastic stretch band 211 is threaded through the installation channel.

[0067] Understandably, the installation channel allows medical staff to select elastic stretch bands of different specifications or performance based on the specific fixed location, the patient's body size, and the required pressure for application.

[0068] like Figures 3 to 5 As shown, in some embodiments of the wound elastic dressing device 10, the wound elastic dressing device further includes a silicone support mesh 4, which is disposed within the pressure mesh 1.

[0069] Understandably, the silicone support mesh 4 allows the pressure mesh 1 to have a certain tension, preventing deformation and ensuring the pressure application effect. Simultaneously, the pressure from the elastic band 211 can be evenly applied to the pressure mesh 1 through the silicone support mesh 4, further enhancing the pressure application effect.

[0070] It should be noted that the silicone support mesh 4 can be configured to be embedded in the interlayer of the pressure mesh 1 by 3D printing. Alternatively, the silicone support mesh 4 can be configured to be pre-made and then melted into the pressure mesh 1.

[0071] The following are the beneficial effects of implementing this utility model:

[0072] This utility model relates to a wound elastic dressing device. The wound elastic dressing device can fix the pressure mesh by fixing the fixing component itself, so that the wound surface of the pressure mesh drives the dressing component to align with the wound. This fixing process can be completed by the adhesion of the first Velcro and the second Velcro.

[0073] In this way, wound treatment can be completed without adhering to the skin, avoiding secondary damage to the wound during wound care, and thus making it suitable for larger wounds. At the same time, since fixation can be achieved without adhering to the skin, it avoids the formation of a poorly breathable adhesive surface between the product and the skin, thereby preventing discomfort at the adhesive surface and improving the comfort of using the product.

[0074] In addition, dressing components of different sizes and specifications can be used for different wounds, which increases the applicability of the product.
