To realize a completely non-contact automatic puncture robot!
In today's clinical medicine, blood sampling is frequently used to diagnose and treat diseases, and the problem of shortage of medical workers has been pointed out. In addition, it is difficult for clinicians to find blood vessels with the naked eye in some patients, and there is a risk of failure in the procedure, as well as serious problems such as needlestick injuries and infections caused by blood contact. To solve these problems, automated robotic blood sampling may be effective. Various types of blood sampling robots have been studied, but many automated puncturing robots use ultrasonic diagnostic imaging equipment. In order to prevent the spread of infectious diseases, it is ideal to estimate the position of blood vessels and achieve automated puncturing without contact with patients. The present invention relates to a method for identifying the position of three-dimensional blood vessels using two infrared cameras without complete contact. By considering the difference in refraction depending on the viewing direction of the cameras, it became possible to identify the position of blood vessels with high accuracy.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of April 1, 2026): - 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 - Showa Medical University - Asahikawa Medical University
