Description

Soluble microneedle easy to pierce skin

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a soluble microneedle which is easy to pierce the skin.

Background

Most of the existing modes of functional cosmetics acting on skin still stay on simple skin surface layer coating, due to the natural protection effect of skin horny layer, the traditional coating mode reagent is equivalent to coating on the glass surface, the full absorption of the effective substances of the cosmetic reagent is difficult to ensure, the appearance of microneedle technology enables the percutaneous conduction and the full absorption of the effective active substances in the cosmetics to be possible, the solid or perforated microneedles prepared by using metal and solid organic polymers have breakthrough development, the action principle of the microneedle pretreats the skin surface to generate micro channels, the cosmetics are coated on the skin surface by the traditional coating mode to achieve the effect that the effective substances can be effectively absorbed by subcutaneous tissues, but the method still has the problems of micro solid and metal fragments fracture and potential safety hazard remained in the skin, and for the stretching and shaping mode, the microneedle structure is formed by contacting and stretching viscous macromolecule liquid drops, because the manufacturing process utilizes the stretching and extending characteristics of viscous fluid, the shape of the manufactured microneedle cannot be freely controlled, meanwhile, because of the limitation of the manufacturing process, the diameter of the needle tip part cannot be minimized, the microneedle structure is more difficult to pierce the skin, if the mechanical strength of the microneedle is reduced, the problem of bending and breaking is easily caused when the microneedle pierces the skin, besides, the existing soluble microneedle is inconvenient to ventilate and is easy to cause discomfort, and meanwhile, certain protective capacity is not provided.
