Development of portable health care device with multi-directional micro dispenser system

成功研制了纳升-微升分配器芯片和血浆提取微滤芯片。此外，便携式血液检测装置的概念模型，只能通过手动旋转磁盘操作已开发。具体结果是，在微点药芯片中实现了重复性分药精度的提高和每10nL的可靠多向注射控制。实验验证了该血液细胞分离微滤芯片的基本性能。同时，找到了内置微型电磁阀的多向开关阀芯片的设计策略，并正在进行样机的制作。并制作了由这些芯片组装而成的微型分配器芯片便携式血液检测装置的概念模型。

The dispenser chip that can divide sample into from nano liter to micro liter order and the microfilter chip for extracting blood plasma were developed successfully. Moreover, the concept model of the portable blood test device that can operate only by rotating the disk manually has beendeveloped. As concrete results, the improvement of repeatability dividing precision and the reliable multi-directional injecting control of each 10nL were achieved in the micro dispenser chip. Basic performances of the blood cell separation microfilter chip were verified experimentally. Also, the design strategy of the multi-directional switching valve chip with built-in the micro solenoid was found and the fabrication of its prototype is in progress. Moreover, the concept model of the portable blood test device with the micro dispenser chip assembled with these chips was fabricated.
