Disposable microneedle device

Abstract

The disposable microneedle device includes a base, a microneedle assembly, a cover body, and several connecting rods that can be dissolved in alcohol; the microneedle assembly includes a base and several microneedles arranged at intervals on the base; the top of the base The same number of conical grooves as the connecting rods are provided on the wall and the bottom wall of the base; the two ends of each connecting rod are all tapered, and one of the ends of each connecting rod is embedded in the bottom wall of the base. Corresponding to a tapered groove, the other end of each connecting rod is embedded in a corresponding tapered groove on the top wall of the base; several connecting rods are arranged at intervals to form an equilateral triangle array; the cover is detachable Fastened on the base, a closed space is formed between the cover and the base, and the microneedle assembly and the connecting rod are located in the closed space. The above invention can effectively prevent secondary use and fundamentally avoid cross-infection.

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...

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. disfigurement or infectious disease

In addition, users cannot judge whether the microneedle device has been used through intuitive observation, which is not conducive to safeguarding their legal rights.

[0004] When the user administers medicine through the microneedle device, the user generally presses the microneedle array, so that the microneedle array instantly generates a large number of micron-sized pores in the skin stratum corneum and epidermis, and then removes the microneedle device, and applies the drug to the skin. Drugs can penetrate and diffuse quickly through the pores of the skin. This method sometimes causes the drug to be contaminated by impurities in the air, which affects the efficacy of the drug, and the drug delivery efficiency is low
