[0002] Plaster is a kind of Chinese medicine for external use, known as thin patch in ancient times. It is made by boiling vegetable oil or animal oil with medicine into a gelatinous substance, which is applied to one side of cloth, paper or leather. It can be attached to the affected area for a long time. It is mainly used to treat sores, boils, swelling and pain, etc.

[0003] In the prior art, commonly used plaster carriers are shown in CN201861993U, which use a medicinal single-sided self-adhesive adhesive as the backing material. An elastic foam ring is pasted in the middle of the adhesive surface of the medicinal single-sided self-adhesive adhesive, and the plaster is applied inside the foam ring before applying the medicine.

[0004] When using the above-mentioned plaster carrier, medical staff need to manually apply the plaster. One method is to use a small spoon to fill the plaster in the foam circle, then use a spoon to spread the plaster evenly in the foam circle, and finally flatten the plaster so that the plaster is evenly and fully spread in the entire foam circle, which is convenient for better absorption and allows the drug to fully play its role. However, when there are a large number of plasters that need to be spread and flattened, manual operation is very time-consuming and laborious.
