An externally-applied patch

Abstract

An externally-applied patch relates to an externally-applied patch, which is composed of nonwoven (1), automatic thermostat heater (2), hydrogel transdermal ointment (3) and plastic film (4). The nonwoven (1) and the automatic thermostat heater are tightly connected, the hydrogel transdermal ointment is coated on the back line of the nonwoven, the automatic thermostat heater is arranged in the middle, and the surface of the hydrogel transdermal ointment (3) is covered with the plastic film. The present invention makes the hydrogel transdermal ointment enable to play medical action for a long time at a certain temperature by the continuous heating of the automatic thermostat heater, thereby reducing the effective time of the medicine, and improving the effect of medicine absorption; and thepresent invention has the advantages of convenient and comfortable use, large drug loading, strong penetrability, easy absorption, no residue, and no contaminated clothing.

Description

Technical field: [0001] The invention relates to an external patch. Background technique: [0002] With the increasing number of patients with bone and joint diseases and related diseases around the world, people urgently need a green, safe, pollution-free, efficient and convenient external health care and rehabilitation treatment method and product. At present, one of the main methods for human to treat bone and joint and related diseases is to use traditional Chinese medicine external patches. Although the efficacy of this patch is relatively significant, there are widespread problems of single technology and backward production technology, which are not convenient for automated mass production; and The body is not tightly pasted, and it is easy to fall off; there is residue, which is easy to pollute the clothes and the environment, and cause skin allergic reactions; the ointment has a small drug load, and the drug acts slowly at a lower temperature (normal temperature), h...
