An elastic scar patch, characterized in that, with the side closest to the wound as the inner layer, it comprises, from the inside out, a medical silicone gel layer, a medical sponge layer impregnated with a drug, and an elastic backing layer; the medical sponge layer impregnated with a drug has an air bladder built into it, and the air bladder is connected to an inflation device."

[0003] Although the above-mentioned technical content discloses the use of airbags to apply pressure to wounds for pressure therapy to reduce the tension of wound skin tissue and avoid or prevent the formation of hypertrophic scars, it solves the problems of existing pressure therapy where the elasticity of elastic garments or elastic sleeves cannot be effectively controlled as needed, and they usually have problems such as discomfort or even intolerance when worn, inconvenience in use and high price.

[0004] However, most existing airbag surfaces have an arc-shaped structure, while the aforementioned patent has the problem that the medical sponge layer is made of porous material. During the airbag inflation process, the medical sponge layer will be over-compressed, so the medical sponge layer cannot evenly transmit the airbag pressure to the skin surface. Therefore, when the existing technology applies pressure to the skin, the edge pressure is less than the center pressure, and the effective pressure application area of ​​the airbag is small. Utility Model Content

[0005] Purpose of the utility model: To provide an elastic scar patch that, through the cooperation of the substrate layer and the outer surface of the airbag, enables the substrate layer to evenly apply pressure to the skin in the middle and edge of the airbag, thus solving the problem of the small effective pressure application area of ​​the airbag in the prior art.

[0006] The technical solution of this utility model is as follows: an elastic scar patch includes: a substrate layer, an air bladder and an elastic backing layer arranged in sequence.

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] This application discloses an elastic scar patch. By cooperating with the outer surface of the air bladder, the substrate layer can evenly apply pressure from the center and edge of the air bladder to the skin, thus solving the problem that the pressure applied to the skin in the prior art is inevitably less at the edge than at the center.

[0032] First embodiment, such as Figure 1-3 The elastic scar patch shown includes: a substrate layer 3, an air bladder 2, and an elastic backing layer 1 arranged in sequence.

[0033] The shape of one side of the substrate layer 3 matches the shape of the outer surface of one side of the airbag 2, so that one side of the substrate layer 3 is attached to the surface of the airbag 2.

[0034] The elastic backing layer 1 is used to fix the substrate layer 3 and the airbag 2 to the skin surface, so that the other side of the substrate assembly is attached to the skin surface.

[0035] The airbag 2 is used to apply pressure to the substrate layer 3 and the elastic backing layer 1. The substrate layer 3 is used to make the pressure of the airbag 2 evenly applied to the skin.

[0036] In this embodiment, the substrate layer 3 is made of rubber, silicone, TPE, or PTFE. The above materials can make the substrate layer 3 both flexible and rigid, so that the pressure of the airbag 2 can be evenly applied to the skin when the substrate layer 3 is in contact with the airbag 2 and the skin.

[0037] The elastic backing layer 1 is made of one of the following materials: medical elastic fabric, elastic polyurethane film, elastic tape, or elastic non-woven fabric coated with medical pressure-sensitive adhesive; the elastic backing layer 1 is colorless and transparent or skin-colored.

[0038] like Figure 1-3 As shown, the airbag 2 has an elliptical structure, but it can also have a square structure. The airbag 2 is connected to the inflation device 21.

[0039] like Figure 1 As shown, this elastic scar patch is used for wounds on the arm. The elastic backing layer 1 is made of medical elastic fabric and is wrapped around the arm several times. The substrate layer 3 is an integral structure. The side of the substrate layer 3 near the airbag 2 has an elliptical groove that matches the airbag 2, and the side of the substrate layer 3 near the skin has an arc-shaped structure that matches the surface of the arm skin.

[0040] The substrate layer 3 may have an adhesive layer on its surface to bond the substrate layer 3 to the airbag 2 and / or to the skin. When the adhesive layer is bonded to the skin, medical adhesive is applied to the pressure layer 32 to form the adhesive layer. The adhesive layer can improve the connection strength between the substrate layer 3, the airbag 2, and the skin, and improve the positioning ability of the pressure application. A release film layer can also be provided on the surface of the adhesive layer to facilitate the transportation, storage, and cutting of the substrate layer 3.

[0041] like Figure 2 and 3 As shown, the elastic scar patch also includes a pressure sensor 4, which is disposed between the substrate layer 3 and the airbag 2, or between the airbag 2 and the elastic backing layer 1.

[0042] In this embodiment, the pressure sensor 4 can be connected to devices such as mobile phones and computers to display the pressure.

[0043] Alternatively, a pressure display module 41 can be set up so that it is connected to the pressure sensor 4 and displays the pressure.

[0044] Alternatively, a pressure control module and an alarm device can be set up, with the pressure control module connected to the pressure sensor 4 and the alarm device connected to the pressure control module. When the pressure detected by the pressure sensor 4 is greater than the set pressure value, the pressure control module sends a signal to control the alarm device to sound an alarm.

[0045] Pressure display module 41, pressure control module and alarm device can also be set at the same time.

[0046] The pressure sensor 4 is positioned between the substrate layer 3 and the airbag 2, which can more accurately detect the real pressure applied to the skin by the elastic scar patch, because the barrier of the substrate layer 3 can reduce the foreign body sensation of the pressure sensor 4 directly pressing against the skin surface.

[0047] Instructions for use: First, select a substrate layer 3 of the corresponding shape according to the wound location. The substrate layer 3 can be appropriately cut according to the wound shape. Then, place the pressure sensor 4 and the uninflated airbag 2 on the substrate layer 3. Then, wrap the elastic backing layer 1 around the arm several times to secure the substrate layer 3 and the airbag 2 to the arm.

[0048] Then, when the pressure between the elastic backing layer 1 and the substrate layer 3 reaches the set value, the inflation of the airbag 2 is stopped. When the pressure sensor 4 is connected to the pressure control module and the alarm device, the pressure detected by the pressure sensor 4 is greater than the set pressure value. When the pressure control module sends a signal to control the alarm device to sound an alarm, the inflation of the airbag 2 is stopped.

[0049] In the second embodiment, based on the first embodiment, the substrate layer 3 includes a pressure-bearing layer 31 and a pressure-applying layer 32.

[0050] like Figure 3 As shown, the substrate layer 3 includes a pressure-bearing layer 31 and a pressure-applying layer 32, which are separable and can be fitted together.

[0051] The shape of the pressure-bearing layer 31 on the side away from the pressure-applying layer 32 matches the shape of the outer surface of the airbag 2, and the side of the pressure-applying layer 32 away from the pressure-bearing layer 31 is used to adhere to the skin surface.

[0052] The separable fit between the pressure-bearing layer 31 and the pressure-applying layer 32 allows for the selection of airbags 2 and pressure-applying layers 32 of different sizes and shapes according to the size and shape of the wound. Different sizes and shapes of pressure-bearing layers 31 can be set according to the size and shape of the airbag 2. During implementation, the pressure-bearing layer 31 or pressure-applying layer 32 can also be cut into the required shape according to the specific circumstances.

[0053] In this embodiment, the surface of the pressure-bearing layer 31 is provided with an adhesive layer for bonding the pressure-bearing layer 31 and the airbag 2 together, and / or for bonding the pressure-bearing layer 31 and the pressure-applying layer 32 together.

[0054] Alternatively, the surface of the pressure layer 32 may be provided with an adhesive layer for bonding the pressure-bearing layer 31 and the pressure layer 32 together, and / or for bonding the pressure layer 32 to the skin.

[0055] When the adhesive layer on the surface of the pressure layer 32 allows the pressure layer 32 to adhere to the skin, medical adhesive needs to be applied to the pressure layer 32 to form an adhesive layer. The adhesive layer can improve the connection strength between the pressure-bearing layer 31, the pressure layer 32, the airbag 2, and the skin, and improve the positioning ability of the pressure application.

[0056] In this embodiment, the elastic scar patch further includes a release film layer disposed on the surface of the adhesive layer.

[0057] The release film facilitates the transportation, storage, and cutting of the pressure-bearing layer 31, pressure-applying layer 32, and sheet 33, which are equipped with adhesive layers.

[0058] In this embodiment, the pressure-bearing layer 31 is made of rubber, silicone, TPE, or PTFE.

[0059] The pressure layer 32 is made of rubber, silicone, TPE, or PTFE.

[0060] In actual use, the pressure-bearing layer 31 and the pressure-applying layer 32 can be made of the same or different materials as needed. The aforementioned materials can make the substrate layer 3 have both flexibility and rigidity. The combination of different materials can give the substrate layer 3 more flexibility and rigidity options, enabling the substrate layer 3 to better fit the airbag 2 and the skin while applying the pressure of the airbag 2 evenly to the skin.

[0061] In the third embodiment, based on the second embodiment, the pressure-bearing layer 31 and / or the pressure-applying layer 32 include: sheet 33.

[0062] like Figure 4 and 5 As shown, the pressure-bearing layer 31 and / or the pressure-applying layer 32 includes: sheet 33, and a plurality of sheet 33 are stacked to form the pressure-bearing layer 31 and / or the pressure-applying layer 32.

[0063] Furthermore, during implementation, the number and shape of the sheet 33 can be selected according to the degree of concavity and convexity of the patient's body parts to form a thickness that matches the body parts, and the sheet 33 is more convenient to be cut into the required shape.

[0064] In this embodiment, the surface of the sheet 33 is provided with an adhesive layer for bonding the stacked sheet 33 together, and / or bonding the sheet 33 to the airbag 2, and / or bonding the sheet 33 to the pressure layer 32.

[0065] The adhesive layer can improve the connection strength between the sheet 33, the airbag 2, and the skin, and improve the positioning ability of the pressure application.

[0066] In this embodiment, the elastic scar patch further includes a release film layer disposed on the surface of the adhesive layer.

[0067] The release film facilitates the transportation, storage, and cutting of the sheet 33 with the adhesive layer.

[0068] In this embodiment, the sheet 33 is made of rubber, silicone, TPE, or PTFE.

[0069] The pressure layer 32 is made of rubber, silicone, TPE, or PTFE.

[0070] In practical use, different or different materials of sheet 33 can be selected to form the pressure-bearing layer 31 as needed.

[0071] The aforementioned materials can give the substrate layer 3 both flexibility and rigidity. Combinations of different materials can give the substrate layer 3 more options for flexibility and rigidity, allowing the substrate layer 3 to better fit the airbag 2 and the skin while applying the pressure of the airbag 2 evenly to the skin.

[0072] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
