VALVE OPENING AND CLOSING DEVICE AND VALVE OPENING AND CLOSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/117017
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a valve opening and closing device with which it is possible to open and close a diaphragm valve of a valve chip reliably by a simple operation. The valve opening and closing device is used for opening and closing a diaphragm valve of a valve chip in which a substrate having a flow passageway and a film including a diaphragm are stacked. The valve opening and closing device comprises: a slide member which is disposed so as to oppose the film, includes at least one protrusion on a surface opposing the film, and is rotated in a state in which the protrusion is pressed against the film to thereby open or close the diaphragm valve; a support body which is disposed so as to oppose the slide member across the valve chip and is fixed in position in the valve opening and closing device; and an elastic body which is disposed between the support body and the valve chip and supports the valve chip at two or more points directly or indirectly.
