Description

technical field [0001] The invention relates to the technical field of medical equipment application, in particular to a subcutaneous drug delivery device for treating corns and calluses on human feet. Background technique [0002] Corn is a kind of physical skin disease, which is caused by long-term friction and pressure of human feet. There is an inverted cone-shaped keratin plug embedded in the papilla dermis in the center of the affected part, which compresses the nerve endings. Cause pain; calluses is the result of long-term pressure or friction on the human foot, local qi and blood flow block, resulting in skin hyperplasia and thickening of keratin. In severe cases, it is hard and swollen due to excessive extrusion or secondary infection, making it impossible to walk. [0003] The current treatment methods commonly used to treat the above two diseases are mainly topical drug application, which mostly use corrosive drugs, such as salicylic acid collodion, etc. It takes...

Problems solved by technology

[0003] The treatment methods usually used to treat the above two diseases are mainly topical drug application, and the external application drugs mostly use corrosive drugs, such as salicylic acid collodion, etc., and the topical drugs are applied on the surface of corns and calluses. It takes about a week to slowly corrode the corns and calluses in the body, and the effect is slow, and the patient usually has a week to endure the pain of walking
