SOLUBLE MICRONEEDLE Russian patent published in 2023 - IPC A61M37/00 A61L31/00 

FIELD: medical technology.

SUBSTANCE: invention relates to a soluble microneedle comprising needles (101) made of a water-soluble material and mounted on one side of a base, which is a sheet material with liquid-permeable cavities. The needles are made of a water-soluble material and are mounted on one side of the base (102), which is a sheet material with cavities permeable to the liquid supplied to the base. The needles (101) are mounted on the base (102) so that the lower part of the needles (101) is directly connected to the base (102), and the connection of the lower part of the needles (101) to the base (102) is provided with a penetrating connecting structure. The lower part of the needles (101) penetrates the base (102), occupying some or all of the cavities of the base (102). The penetrating connecting structure dissolves under the action of a liquid supplied to the base and penetrating into the cavities of the base.

EFFECT: implementation of a soluble microneedle with an easy-to-use design, in which the penetrating structure connecting the needles with the base can be dissolved quickly and efficiently.
