Device and method for preparing slow-release analgesic transdermal patch

Abstract

The invention relates to the technical field of transdermal patch preparation devices, in particular to a sustained-release analgesic transdermal patch preparation device and method, and provides the following scheme that the sustained-release analgesic transdermal patch preparation device comprises a base, the top surface of the base is fixedly connected with a material storage box and a supporting rod, the top surface of the material storage box is open, and a push plate is slidably connected in the material storage box; a coating roller shaft is rotatably connected to the interior of an opening in the top of the storage box, a sixth plate is fixedly connected to the side, close to the supporting rod, of the storage box, a third column is rotatably connected to one side of the sixth plate and is in transmission connection with the coating roller shaft through a fourth belt assembly, and a connecting rope is fixedly connected to a push plate. And one end of the connecting rope is fixedly connected with the third column. According to the patch shearing device, the purpose of continuously shearing the whole patch is achieved, and the shearing efficiency of the patch is improved.

Description

technical field [0001] The invention relates to the field of devices for preparing transdermal patches, in particular to a device and method for preparing sustained-release analgesic transdermal patches. Background technique [0002] Transdermal patches are a unique combination of traditional medicine and modern science. They are very popular because of their wide range of adaptations. Transdermal patches are generally used in the form of drug patches, which include fabric carriers, protective films and The medicament on the fabric carrier, the medicament is located between the protective film and the fabric carrier, different medicament formulations can have different therapeutic effects, some existing medicament formulations include adhesive polymer matrix, the matrix contains cannabinoids, contains oleic acid The carrier, wherein the amount of oleic acid is about 7% to about 12% by weight of the polymer matrix, and an exogenous terpene comprising cineole, wherein the amou...

[0002] Transdermal patches are a unique combination of traditional medicine and modern science. They are popular because of their wide range of treatments. Transdermal patches are generally used in the form of drug patches, which include fabric carriers, protective films and Medication on a fabric carrier, the medicament is located between the protective film and the fabric carrier, different medicament formulations can have different therapeutic effects, some existing medicament formulations include an adhesive polymer matrix, the matrix contains cannabinoids, contains oleic acid A carrier wherein the amount of oleic acid is from about 7% to about 12% by weight of the polymer matrix, exogenous terpenes comprising cineole, wherein the amount of cineole is from about 0.3% to about 0.7% by weight of the polymer matrix , and penetrants containing dodecylmethyl sulfoxide, etc., can play a role in slow-release analgesia; some manufacturers generally produce a large patch first, and then apply it as needed Cutting into patches of different sizes, when producing large patches, due to the cutting method, stop cutting is used (that is, during the operation of the production equipment, when the transmission device carrying the patch moves to the cutting position, Need to stop and wait for the cutting to be completed before transferring), this method makes the production efficiency lower;
