Problems solved by technology

[0008] However, the problem with the above tools is that the process of manufacturing the device is complicated, so it is difficult to mass-produce the device at a very low cost
For example, circular thin plates should be assembled alternately, so it is difficult to manufacture this tool due to the above
There is thus a disadvantage that the above tool cannot be manufactured by one molding process, and the manufacturing time becomes long

Abstract

A micro-needle roller and a forming mold thereof are provided to simplify the structure thereof, and to reduce the processing time to be produced in a mass production at a low manufacturing cost. A micro-needle roller includes a cylindrical needle roller(11), plural micro-needles(25) and a roller handle. The micro-needles are formed to protrude from the outer circumference of the roller head. The roller handle is coupled to the roller head to make the roller head rotate. The roller head and the micro-needles are formed of a polymer resin material and are integrally formed. The polymer resin is a thermoplastic resin or a thermosetting resin. The roller handle has a roller head coupling portion having two clamp arms(44) having a rotary shaft protrusions(45).

Description

technical field [0001] The invention relates to a microneedle roller assembly, more particularly to a microneedle roller assembly for delivering medicine through skin tissue. Background technique [0002] Generally, in the method of transdermal drug delivery, it is difficult for the drug to penetrate the stratum corneum, so the absorption rate of the drug is extremely low. Specifically, the greater the molecular weight of the drug, the lower the drug absorption rate. In order to solve the above-mentioned problems, techniques using microneedles have been proposed. In this technology, microneedles are used to create channels through part or all of the epidermis of the skin, and drugs are delivered through these channels to the epidermis or sub-epidermal layer of the skin. [0003] According to the above technology using microneedles, drugs with a large molecular weight such as insulin, hormone drugs, etc. can be easily delivered. Also, burns or scars can be healed naturally...
