Embodiment Construction

[0057] A different-plane microneedle array, including coplanar microneedles 1 and a substrate 2, coplanar microneedles 1 including one or more needlepoints and a base connecting the needlepoints, the needlepoints and bases are in the same plane, and more than two coplanar microneedles The needle 1 is assembled on the substrate 2, and an elastic cushion block 19 is arranged between the microneedles 1 on the same plane.

[0058] The elastic cushion block 19 has the following functions: 1. It can isolate and control the distance between microneedles 1 on the same plane; The degree of deformation of the elastic buffer block 19 can further control the length of the microneedle body protruding from the elastic buffer block 19 to adjust the depth of penetration into the skin.

[0059] The present invention intends to integrate the advantages of coplanar microneedles and non-planar microneedles, and combine the advantages of low-cost polymer microneedle technology.

[0060] The copla...

Abstract

The invention relates to a nonplanar microneedle array and a manufacturing method thereof. The nonplanar microneedle array comprises coplanar microneedles and a substrate, wherein more than two coplanar microneedles are assembled on the substrate, the substrate is a substrate provided with a clamp, which comprises a substrate body and the clamp, the substrate body is provided with at least two positioning raised lines, the clamp is provided with clamping grooves in one-to-one correspondence with the positioning raised lines, the clamp is installed on the substrate body, the positioning raised lines are embedded in the clamping grooves, a clamping interval is left between each clamping groove and each positioning raised line, a bottom seat of the coplanar microneedles is placed in the clamping intervals, and an elastic element which pushes the clamp to horizontally move towards one shrink side of the clamping intervals is arranged between the clamp and the substrate body so as to clamp the bottom seat of the coplanar microneedles. The nonplanar microneedle array has the advantages that shapes of needle tips of the coplanar microneedles are easy to control, the needle tips are good in quality, and the microneedle array assembled by arranging a plurality of the coplanar microneedles side by side not only can guarantee the needle tips, needle shapes and the needle length, but also can meet the requirement for the density of the needle tips.

Description

[0001] The patent application of the present invention is a divisional application, the original application number is 201410266984.8, the application date is June 16, 2014, and the invention name is: different planar microneedle array and its manufacturing method. technical field [0002] The invention relates to the technical field of medical cosmetic devices and microneedles for medical injection, in particular to a non-planar microneedle array and a manufacturing method thereof. Background technique [0003] Microneedle transdermal drug delivery is an emerging drug delivery technology. By pressing the microneedles, a large number of micron-sized pores are generated in the stratum corneum and epidermis of the skin, and the drug penetrates into a large number of blood vessels in the dermis of the skin through these pores, thereby achieving Transdermal administration. Microneedles can achieve integrated, portable, painless, precise, and efficient drug delivery during the tr...
