Abstract
The present invention relates to a liquid channel device capable of easily opening the liquid channel from the closed mode, including a base plate in which a liquid channel, through which a liquid containing at least one of a sample and a reagent, flows, and a metering chamber for holding the liquid, are formed to at least one side thereof, the metering chamber has a liquid transport section for transporting the liquid inside the chamber downstream, and this liquid transport section is operated by means of external pressing on a cover plate in the area opposite the metering chamber.
Claims3
A liquid channel device including a base plate in which a liquid channel through which a liquid flows and one or more liquid chambers for holding the liquid are formed to at least one surface thereof, and a cover plate which is laminated to the channel formation surface in which the liquid channel and the liquid chambers of the base plate are formed;
- wherein the liquid channel device further includes an opening section for opening a portion of the liquid channel from a closed mode;
- the opening section includes a stopper which is disposed to a portion of the liquid channel, and undergoes plastic deformation by means of external pressing on the cover plate or a floor of the liquid channel, thereby placing the liquid channel in an open mode, and
- the stopper is formed by coating a stopper forming material for forming the stopper to a portion of the liquid channel, and the stopper forming material includes hollow beads which are deformed and broken by subjecting to pressing.
