Example Embodiment

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0025] See Figure 1 to Figure 3 , The present invention relates to a disposable microneedle device, the preferred embodiment of which includes a base 10, a microneedle assembly 40, a cover 20 and a plurality of alcohol-soluble connecting rods 30.

[0026] The microneedle assembly 40 includes a base 41 and a plurality of microneedles 43 arranged on the base 41 and distributed at intervals. Several microneedles 43 are integrally formed with the base 41 . The top wall of the base 41 and the bottom wall of the base 10 are respectively provided with the same number of conical grooves as the connecting rods 30 . Both ends of each connecting rod 30 are tapered, one end of each connecting rod 30 is embedded in a corresponding conical groove on the bottom wall of the base 10 , and the other end of each connecting rod 30 is embedded in a corresponding...

Abstract

The invention discloses a disposable microneedle device which comprises a base, a microneedle assembly, a cover and a plurality of connecting rods capable of being dissolved into ethyl alcohol. The microneedle assembly comprises a foundation base and a plurality of microneedles distributed on the foundation base at intervals. The top wall of the foundation base and the bottom wall of the base are respectively provided with conical grooves with the same number as the connecting rods, the two tail ends of each connecting rod are in a conical shape, one tail end of each connecting rod is embedded into one corresponding conical groove in the bottom wall of the base, the other tail end of each connecting rod is embedded into one corresponding conical groove in the top wall of the foundation base, the connecting rods are arranged at intervals to form a regular triangular array, the cover is detachably buckled to the base, a closed space is formed between the cover and the base, and the microneedle assembly and the connecting rods are located in the closed space. The disposable microneedle device can be effectively prevented from being used twice, and cross infection is fundamentally avoided.

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 dev...
