Problems solved by technology

Although the local body temperature can be increased through the plastic wrap to increase the absorption rate of the anesthetic, however, this method of wrapping in plastic wrap is not only troublesome, but also the waiting time for the anesthesia to take effect is still too long (about 30 to 60 minutes)
While waiting for anesthesia to take effect for a long time, it will virtually increase the anxiety of surgical patients

Abstract

The invention relates to a hot compress patch for local skin anesthesia. The hot compress patch for the local skin anesthesia is characterized by comprising a sheet base material, a heating chip, an anesthetic liposome layer and a polymeric glucoprotein layer, wherein the sheet base material comprises a first surface and a second surface; the heating chip is attached to the first surface of the sheet base material; the anesthetic liposome layer is provided with liposomes coated with an anesthetic, and the surface of one side of the anesthetic liposome layer covers the second surface of the sheet base material; and the polymeric glucoprotein layer covers the surface of the other side of the anesthetic liposome layer. The hot compress patch for the local skin anesthesia has the advantages that: the penetrating power of the anesthetic is increased by improving the structure of a medicament layer of the anesthetic; and moreover, by arranging the heating chip, the temperature of the skin is locally raised, and the absorption of the anesthetic is further accelerated, so the anesthesia time is remarkably shortened, and the trouble of wrapping a preservative film is eliminated.

Description

Technical field [0001] The invention relates to the field of medical anesthesia, and relates to local skin anesthesia supplies, in particular to a local skin anesthesia hot compress. Background technique [0002] Generally, when dermatology and plastic surgery perform minor operations on superficial skin such as laser surgery or high-frequency electrocautery, in order to reduce the pain caused by the operation, skin anesthesia ointment is usually applied to the operation site before the operation. Because human skin is mainly composed of epidermis, dermis and subcutaneous tissue, the outermost layer of the epidermis is covered by the stratum corneum, which is the biggest obstacle for drugs to penetrate the skin. Since the stratum corneum is hydrophobic and negatively charged, it greatly hinders the percutaneous penetration of water-soluble drugs. Due to the barrier properties of the skin, it is easy to make it difficult for the dose of anesthetic to penetrate the skin to re...
