Embodiment 1

[0045] This embodiment provides a plastic silicone gel comprising a silicone gel main material 1 and polyethylene terephthalate (PETG) 2. The silicone gel main material 1 includes polysilicone and a small amount of polytetrafluoroethylene Vinyl fluoride, the molecules of the two polymers form an interpenetrating polymer network structure.

[0046]The product provided by this embodiment has good plasticity, is placed in an oven, a heating plate or other heating equipment, and after being heated at 150-180° C. for 2-8 minutes, the product becomes soft, and is made into a face shield adapted to an anatomical structure for use by patients. For example, the care of facial scars.

[0047] To use, remove the release paper on this moldable silicone gel. Then put the silica gel face down on a flat plate, and heat it in an oven, heating plate or other heating equipment at 150-180°C for 2-8 minutes. Use heat-resistant gloves to take out the plastic silicone gel, pass through the patien...

Embodiment 2

[0053] This embodiment provides a translucent silicone gel film comprising a silicone gel main material 1 and polycaprolactone (PCL) 2, wherein the silicone gel main material 1 includes polysilicone and a small amount of polytetrafluoroethylene , the molecules of the two polymers form an interpenetrating polymer network structure. Cut the silicone gel film into different sizes.

[0054] The product provided by this embodiment has good plasticity, and the product can be softened when placed in warm water at 50-75°C for a long enough time, and can be made into a sticking film suitable for bending joints, for patients to apply such as bending arms, ankles, etc. Scar care for bent joints. The bending strength of this material at room temperature is ≥20MPa, which is sufficient to limit the movement of the bending joints.

[0055] To use, remove the release paper on this moldable silicone gel. The product is then placed in water at 50-75°C for a sufficient time to soften the gel....

Abstract

The invention provides plastic silica gel attached on a skin scar. The plastic silica gel comprises at least two material layers, wherein a first material layer is made of a silica gel main body material and is in direct contact with skin; a second material layer is made of a structural material and used for forming and fixing the shape of the silica gel main body material, and the first material layer is attached onto the second material layer. The invention also provides a production method of the plastic silica gel used for preventing and intervening the scar and scar proliferation. The plastic silica gel used for preventing and intervening the scar and scar proliferation adopts a thermoplastic polyester material as a medical splint material for the silica gel main body material, can be softened after being heated to a certain temperature, can form the required shape at will and can keep and fix the formed shape after being cooled, so that silica gel clings to the skin scar, and good prevention and treatment effects on the scar and scar proliferation are realized.

Description

technical field [0001] The invention relates to the application of a plastic silicone gel material in the medical field, in particular to a plastic silicone gel for preventing and intervening scars and scar hyperplasia and a method for making the plastic silicone gel. Background technique [0002] In order to prevent and treat scar hyperplasia, compression therapy is widely used clinically. In 1983, Perkin et al. put a silicone gel film between the skin and the elastic suit to prevent direct friction between the elastic belt and the scar when using the elastic belt to compress the scar, and found that the silicone gel (silicone gel) has the effect of preventing scar hyperplasia , the effect is much better than those who use elastic band alone. Therefore, the inhibitory effect of silicone gel on scars has been uncovered and has been widely valued. [0003] In some scars such as the face and limbs, silicone gel needs to be attached to the skin according to the shape of the s...
