Fraunhofer Institute for Electronic Microsystems and Solid State Technologies EMFTMedical technology is developing rapidly, with innovative technologies playing a key role in improving patient care. An outstanding example of this is the collaboration between Fraunhofer EMFT and the Japanese medical technology company Daiken Medical. At the heart of this partnership is the development and successful licensing of the world's smallest micromembrane pump, which not only revolutionizes the possibilities of microdosing, but also paves the way for new applications in pain therapy. A significant step in this process was the technology transfer of the patented micro-membrane pump from Fraunhofer EMFT to the medium-sized company Daiken Medical in Osaka, which is now advancing the PCA system "Amy," enabling patients to control their pain treatment themselves.
New technologies for precise pain therapy
Smallest micro membrane pump for precise dosing
Innovative micro-membrane pump platform
Fraunhofer EMFT has established itself as a leading provider in the development of robust piezo micro-pumps. These micro-pumps are characterized by their ability to dose precise amounts of gases and liquids, making them ideal for micro-dosing systems. Two development platforms can be utilized: silicon on 8-inch wafer level and metal foils (stainless steel or titanium), allowing for a wide range of micro-pumps to be realized. The performance data of the micro-pump regarding back pressure capability, bubble tolerance, and size set new standards.
The smallest silicon micro-membrane pump measures just 3.5 x 3.5 x 0.6 mm³, while the largest metal pump has dimensions of 20 x 20 x 2 mm³. Its compact dimensions allow for integration into various medical devices without compromising performance. This micro-pump is not only small but also robust and reliable, making it a preferred choice for precise dosing applications.
Precise and effective pain therapy
The PCA system "Amy" (PCA: Patient Controlled Analgesia) from Daiken Medical has been on the Japanese market since 2021 and utilizes the high-precision metal micro-pump with dimensions of 10x10x2 mm³, which also incorporates a safety valve licensed from Fraunhofer EMFT to ensure safe and accurate infusion of pain medications. The micro-pump is located between the medication reservoir and the control unit, and is integrated into the medication tube as a disposable part. During use, it is inserted by the doctor into the control unit. The user-friendliness of the solution is supported by a companion smartphone app (Amy's Window), which allows for easy control and monitoring of the infusion. This not only improves comfort for patients but also enhances the overall efficiency of pain therapy.
Through the combination of innovative technology and strategic partnership, the project sets new standards in medical technology and strengthens the position of Fraunhofer EMFT and Daiken Medical in the international market.
