Problems solved by technology

The production process is relatively complicated, and there is actually a layer of silicone film between the drug-containing filling layer and the silicone gel. Macromolecular drugs are not easy to penetrate into the silicone gel layer through the silicone film, thereby affecting the treatment effect on scars. and treatment cycle

Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 , 2 As shown, a drug storage type scar removal silicone gel patch disclosed by the present invention includes a silicone membrane 1 and a silicone gel layer 2, the silicone membrane 1 and the silicone gel layer 2 are bonded together, and the silicone gel layer 2 is provided with a drug storage storehouse 3, which contains a mixed solution of medicine and organic silicon polymer. The preferred thickness of the silicone gel layer 2 is between 1.0-4.0 mm, and the silicone gel layer 2 is a medical room temperature vulcanization type. silicone gel. According to different therapeutic purposes, the drugs can be corticosteroid drugs, blood-activating and stasis-removing drugs, heat-clearing and detoxifying drugs, pain-relieving, itching-relieving and swelling-reducing drugs, yin-nourishing and beauty-en...

Abstract

The invention relates to a drug-reservoir type scar-removing silicone gel paster and a preparation method thereof. The drug-reservoir type scar-removing silicone gel paster is characterized by comprising a silicone membrane and a silicone gel layer, wherein a drug reservoir is arranged in the silicone gel layer, and the inner part of the drug reservoir contains drugs and organic silicon polymer mixed liquid. The drug reservoir is directly arranged in the silicone gel layer, so the drug-reservoir type scar-removing silicone gel paster solves the problem that active ingredients in the drugs are isolated by the silicone membrane to cause macromolecular drugs to difficultly penetrate. The drugs in the drug-reservoir can better penetrate the silicone gel layer and play a role of treatment for scars, so that the paster shortens the treatment cycle and increases the treatment effect for the scars. In addition, the drug-reservoir type scar-removing silicone gel paster has simple preparation method, does not need complex molding equipment and is easy to produce and operate.

Description

technical field [0001] The invention relates to a medical patch and a preparation method thereof, in particular to a drug storage type scar-removing silica gel patch and a preparation method thereof. Background technique [0002] Trauma, surgical wounds, and burns will inevitably leave scars after the wounds heal on the wound surface of the human body. Among them, hypertrophic scars and keloids especially affect the appearance and beauty. Since Perkins and others discovered that silicone gel has the effect of softening scars in 1982, scholars from various countries have conducted a lot of research, proving that silicone products can prevent and treat scars and have invented many medical silicone products, but they are the most widely used. It's a silicone gel patch. The material of the silicone gel patch itself is high-purity medical silica gel, without any drug additives. Simple silicone gel has a good preventive and therapeutic effect on hypertrophic scars, but the treatm...
