MICROFLUID DEVICE PUMP AND METHOD OF TRANSFERRING FLUID

摘要

PROBLEM TO BE SOLVED: To provide a method of transferring a fluid which enables the use of a pump mechanism of small size and simple structure and which dispenses with a complicated control and to provide, moreover, a microfluid device pump which can be manufactured easily with the simple structure and having the pump mechanism which has good quantitativeness and which can be applied to gas transfer as well. SOLUTION: The method of transferring the fluid includes (i) a step of circulating the fluid by moving the pressed part in the direction of a valve while deforming a capillary tube-like flow path cross section by pressing the pressed part and opening the valve by the pressurization of the fluid by using the microfluid device pump having the valve opened by the pressurization of the fluid on the way of the capillary tube-like flow path and the pressed part which deforms the flow path by the pressing, or (ii) a step of transferring the fluid by moving the pressed part in the reverse direction to the valve while deforming the pressed part by pressing from the exterior and opening the valve by the pressure reduction of the fluid by using the microfluid device pump having the valve opened by the pressurization of the fluid on the way of the capillary tube-like flow path and the pressed part which deforms the flow path by the pressing.
