Tohoku Univ. Technology : Stick injection "microneedle pump": T18-477_T20-579
Flow-Generating Microneedles Enable Fast Injection of Drugs and Vaccines
Microneedles with lots of painless needles are expected to spread rapidly in the beauty field and be used more for self-medication and simple vaccine administration, which are the cornerstones of remote medical treatment. However, conventional methods of applying (or encapsulating) a drug or vaccine to a microneedle and eluting them after skin prick have limited injection volume and speed. The inventors have developed a porous microneedle (PMN), which imparts an electrical "flow" (electroosmotic flow) that allows for high volume and high speed injection with an electric "microneedle pump" and rapid collection of subcutaneous tissue fluid.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
