Microfluid handling device

摘要

There is provided an inexpensive microfluid handling device which is capable of simply controlling the flow of plural kinds of very small amounts of liquids (microsamples) independently of a driving source and which is suitable for a POC inspection. In the microfluid handling device 1, there is formed a fine groove 10 forming a microchannel for allowing a liquid sample to move due to capillarity. At one end of the fine groove 10 of the microfluid handling device 1, a storage portion 6 (7) is formed for injecting a sample S1 (S2) into the fine groove 10. At the other end of the fine groove 10, there is formed a final storage portion 8 capable of being used for taking out the sample S1 (S2) flowing through the fine groove 10 due to capillarity. The storage portion 6 (7) is open to the atmosphere. The bottom of the final storage portion 8 is sealed with a sealing protrusion 11 capable of being broken off, and is open by breaking the sealing protrusion 11 off.
