Description

technical field

[0001] The invention relates to a disposable microneedle device. Background technique

[0002] Because the microneedles of the microneedle device are sharp and short, and the stratum corneum of the skin has no nerve tissue and blood vessels, there will be no pain and bleeding when used, and the minimally invasive small holes can heal in a short time, so the microneedle device It is widely used not only in medical drug delivery, but also in promoting the absorption and penetration of beauty products.

[0003] Existing microneedle devices generally include a base and a microneedle array assembly, and the microneedle array assembly is fixed on the base by glue. In practical application, some beauty parlors will reuse the used microneedle device after soaking it in alcohol in order to save costs. This will bring the risk of cross-infection to the user. Disfigured or infected with infectious diseases. In addition, users cannot judge whether the microneedle devi...
