Chip for analyzing fluids being moved without an outside power source

A chip for analyzing fluid being moved without an outside power source, comprising:

• upper and lower plates assembled with each other;
• a channel through which the fluid moves and formed inside the chip between the upper and lower plates, the channel comprising:
• a pre-treatment portion into which fluid of a target-being analyzed substance is injected and mixed with an identification substance, wherein the pre-treatment portion includes:
• a specimen injection portion which receives the fluid injected through a specimen injection opening formed at the upper plate of the chip, the specimen injection portion having a first ceiling formed at a lower surface of the upper plate and spaced apart from a bottom formed on an upper surface of the lower plate of the chip;
• a first buffer portion arranged downstream of the specimen injection portion, such that the fluid is firstly received in the first buffer portion, the first buffer portion having a second ceiling formed at the lower surface of the upper plate and arranged downstream of the first ceiling, wherein the second ceiling is upwardly extended from the first ceiling so that the second ceiling is higher than the first ceiling from the bottom;
• and
• at least one specimen leading guide which is provided between the specimen injection portion and the first buffer portion and destroys surface tension of the fluid flow moving from the specimen injection portion to the first buffer portion side and thus stabilizes flow surface of the fluid,
• wherein the specimen leading guide comprises plural specimen leading guides which protrude from a center area of a slanted surface formed at the lower surface of the upper plate and connecting the first ceiling and the second ceiling, to be spaced from each other at a predetermined space;
• a channel portion connected to the pre-treatment portion and arranged downstream of the pre-treatment portion, the channel portion through which the fluid injected into the pre-treatment portion is moved and in which a specific reaction of the fluid such as an antigen-antibody reaction is conducted;
• and
• a washing portion connected to the channel portion and arranged downstream of the channel portion, the washing portion into which the fluid passing through the channel portion is received.
