Patent ID: 6838055

Claim:
A microchip comprising: a specimen flow pass that is a fine pass allowing a specimen to be transported toward one end thereof; a reagent flow pass that is a fine pass connected with the one end of the specimen flow pass, said reagent flow pass allowing at least one reagent to be transported for reaction with the specimen; a confluence flow pass that extends from the one end of the specimen flow pass, the confluence flow pass allowing the confluent specimen and reagent to be transported therethrough; a sensing portion provided at a position adjacent to a part of the confluence flow pass, wherein a reaction of the specimen and the reagent is capable of being detected or observed thereat; a micro pump which is capable of bi-directional suction and discharge of the specimen and the reagent and is provided at the specimen flow pass and the reagent flow pass or at the confluence flow pass; and a driver which applies a driving pulse to the micro pump to drive the micro pump for reciprocating motion.
