Hot-compress plaster patch

Abstract

The invention provides a hot-compress plaster patch. The hot-compress plaster patch comprises a plaster cloth and a medicine block, a medicine application area is arranged in the center of the plastercloth, an adhesive layer is arranged outside the medicine application area, the medicine application area is covered with a mesh cloth, the outer edge of the net cloth is fixed on the upper surface of the plaster cloth, and the medicine block is arranged between the net cloth and the plaster cloth; a heating circuit is arranged on the lower surface of the plaster cloth, and the heating circuit comprises a direct current power supply E, a switch S, operational amplifier integrated single channels IC1-IC2, a thermocouple BT, a bidirectional thyristor SCR, an electric heating wire RL, resistorsR1-R5, a capacitor C and an LED. The hot-compress plaster patch has the advantages that the plaster patch is provided with the electric heating wire, and heating can be conducted on the plaster patchin the application process to constantly maintain a hot-compress effect to ensure the effect of medicine; a temperature feedback circuit is arranged in the heating circuit, and the temperature of theplaster patch can be maintained within a fixed range to prevent skin from being burnt due to excessively high heating temperature or prevent plaster from outflowing; by arranging the net cloth, the medicine block can be limited between the net cloth and the plaster cloth to prevent the medicine block from scattering and falling during the application process.

Description

technical field [0001] The invention relates to a plaster, in particular to a hot compress plaster. Background technique [0002] Plaster plaster is an external preparation made by refining medicinal materials, edible vegetable oil and red pill, and spreading it on plaster cloth. Anti-inflammatory, pain relieving, promoting blood circulation and removing stasis, nourishing qi and nourishing blood, dredging channels and collaterals, strengthening tendons and bones, relaxing tendons and activating collaterals, resuscitating the bones, expelling wind and cold, etc. [0003] Plasters should be applied with hot compresses, so as to open the pores of the skin, relax the pores, and promote drug penetration. Therefore, in the current practice of traditional Chinese medicine, the plasters are usually heated before application. However, in order to avoid scalding the skin or spilling the plaster, the heating temperature of the plaster before application should not be too high, which ...

AI Technical Summary

Problems solved by technology

However, in order to avoid scalding the skin or spilling the plaster, the heating temperature of the plaster before application should not be too high, which determines that the time for keeping the heat of the plaster is very limited

After the temperature of the plaster drops rapidly during the application process, the penetration of the medicine is greatly reduced, which greatly reduces the efficacy of the medicine
