LIQUID FEEDER

摘要

PROBLEM TO BE SOLVED: To provide a small-sized inexpensive liquid feeder suitably used in various analyzers inclusive of a POC analyzer and the like. SOLUTION: The liquid feeder is equipped with a liquid housing body having a liquid storage tank and a uncompressible medium housing body for housing an uncompressible medium for transmitting pressure for causing the volumetric change of the liquid storage tank. A diaphragm deformable so as to protrude toward the inside or outside of the liquid storage tank is provided on the liquid storage tank. Further, the uncompressible medium housing body is equipped with a first medium storage tank equipped with a transforming means for producing pressure and filled with the uncompressible medium and a second medium storage tank allowed to communicate with the first medium storage tank by an uncompressible medium flow channel. The liquid storage tank and the second medium storage tank are arranged adjascent to each other so as to hold the diaphragm and the diaphragm is deformed so as to follow a change in the pressure applied to the uncompressible medium by the transforming means.
