Patent attributes
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.
