Technical Field

The invention relates to the field of medical auxiliary instruments, in particular to a split type gradient pressure patch for body surface skin.

Background

The body surface skin usually needs pressurization for hemostasis after operation, and also needs pressurization for preventing scar formation, and also needs pressurization treatment if scar hyperplasia is formed. Particularly, hyperplastic scars protruding from the surface of the skin are common diseases and frequently encountered diseases in China, and are hyperplastic scars in the healing process of skin wounds, accompanied by symptoms of pruritus, ulceration and the like, which are continuously enlarged, even invade surrounding normal skin tissues, develop into keloids and even canceration, and seriously affect the life quality of patients. The traditional treatment methods comprise surgical excision (large wound and easy recurrence), superficial radiotherapy (radiation hazard), scar needle (large side effect of hormone therapy) and the like, and have limited effect and easy recurrence. The Chinese cheloid clinical treatment recommended guideline compiled by the expert group of the Chinese beauty Association clearly provides that the compression treatment method is an effective method for preventing scar hyperplasia and treating hyperplastic scars.

The skin has a bleeding condition under the skin after an operation, hematoma is easy to form, and the wound healing is influenced. Therefore, local pressurization of the wound can effectively prevent subcutaneous hematoma and promote wound healing. The formed hyperplastic skin scar can be flattened and softened by means of pressurization, so that the purpose of treatment is achieved. In the current body surface scar treatment products, represented by scar treatment produced by Allence company in the United states and skin care produced by Molnlycke company in Sweden, the principles of liquid silicone moisture retention and surface tension are applied to prevent scar hyperplasia, but the forming pressure is small, and the effect on the formed scar is limited. Particularly, it is difficult to apply pressure to a particular part of the skin, such as the chest, the outer side of the upper arm, and the earlobe, where scars are likely to form. In addition, the scar has special shape and different sizes, and is difficult to realize individual treatment.

The invention designs a split type pressurization method, after an elastic body is compressed and deformed under the action of external force, the space is sealed, pressure difference formed by atmospheric pressure and sponge resilience force is transmitted to the surface of skin, and meanwhile, the bottom layer of the split type design can be cut according to the shape of a part needing pressurization; the double-layer elastomer layer can effectively realize gradient pressurization, the pressure of the central fixed point is high, the pressure of the edge part is low, and the treatment effect is improved.
