Abstract

The invention discloses a scar treatment strip and a preparation method thereof. The scar treatment strip comprises a porous basement layer, a silica gel layer and a parting layer arranged sequentially, wherein the silica gel layer is prepared from, by weight, 100 parts of A1, 0.1-10 parts of B1, 0-10 parts of resinous polysiloxane, 0.001-0.5 part of first platinum catalyst and 0.001-0.5 part of first alkynol polymerization inhibitor, wherein A1 is liquid polysiloxane containing at least two alkenyl, and the viscosity of the liquid polysiloxane is in 1000 mpas-100000 mpas, B1 is organic hydrogen siloxane containing at least three silicon key bonding hydrogen atoms; the scar treatment strip breaks through the material selection range of the traditional scar treatment strips, transfers fromnon-permeable film material to porous material, the obtained scar treatment strip is soft, fit the body, and the increasing of the permeability of the porous material makes the scar treatment strip more comfortable.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a scar sticker and a manufacturing method thereof. Background technique [0002] After burns, trauma or surgery, patients often form scar hyperplasia or keloids on the surface of the wound healing, which not only affect the appearance, but also lead to limb dysfunction and even cancer. For the treatment of scars, pressure therapy is routinely used. Although good results are achieved, the pain is severe and unbearable at the initial stage of using elastic sleeves. Some anatomical areas that are not easily subject to pressure, such as buttocks, abdomen, waist, etc., have poor pressure therapy effects and are not easily accepted by patients; there are also injections of hormones into scars, which have a better therapeutic effect, but the early pain and itching symptoms of scars The relief is not obvious, it is not suitable for the prevention and treatment of large scars, a...
