Embodiment Construction
[0021] The transdermal drug delivery patch as shown in the figure is provided with a drug delivery patch 1. The drug delivery patch 1 can be a sheet of polymer material, or it can be cardboard, rubber sheet, foam board, etc. The drug delivery patch 1 is provided with a drug storage tank, and the drug storage tank is equipped with a drug storage tank 2. The drug storage tank 2 is a liquid-absorbent material that can store drugs. The liquid-absorbent material can be cotton yarn, and the liquid-absorbent material can be Sponge, liquid-absorbent material can be felt, etc. The reservoir 2 can be filled with solutions, suspensions, solid powders, gels, creams, emulsions, liposomes, with a large storage range and limitations in use Small, large storage capacity, strong sealing. An adhesive layer 3 is arranged on the frame of the medicine storage tank, and the adhesive layer 3 can be pasted on the skin. The adhesive layer 3 is provided with an anti-adhesive layer 4, which is a plastic...

The invention relates to a transdermal medicament conveying paste and a preparation method thereof, and relates to a medicament conveying device and a preparation method thereof. The transdermal medicament conveying paste is provided with a medicament conveying paste, a medicament storage groove is arranged on the medicament conveying paste, a medicament storehouse is arranged in the medicament storage groove, a mucilage glue layer is arranged on the frame of the medicament groove, and an anti-sticking layer is arranged on the mucilage glue layer. The preparation method comprises the steps of: pressing medicament storage paste plates to form the concave medicament storage groove; cutting absorbent materials into the medicament storehouse according with the medicament storage groove; injecting medicaments into the medicament storage storehouse; sticking the medicament storage groove with the medicament storehouse; coating the mucilage glue layer on the frame of the medicament storage groove; and sealing finished products of the anti-sticking layer on the mucilage glue layer on the frame of the medicament storage groove. Because the medicament storage groove is arranged on the medicament conveying paste, the medicament storehouse is arranged in the medicament storage groove, and solution, mixed suspension, solid powder, gelatin, emulsifiable paste, lactescence and medicaments with liposome formulations can be injected into the medicament storehouse, the transdermal medicament conveying paste has the advantages of large medicament storage range, small use limitations, large medicament storage quantity and strong closure, and is suitable for conveying medicaments in formulation such as solution, mixed suspension, solid powder, gelatin, emulsifiable paste, lactescence and liposome.
Description
