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.
Claims6
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 a channel formation surface of the base plate where the liquid channel and the liquid chambers 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 fixed to a portion of the liquid channel by a weakly adhered layer;
- a concave section capable of housing the stopper is formed at a position on an inner surface of the cover plate or a floor of the liquid channel that is opposite the stopper, and a strongly adhered layer, which has a larger adhesive strength than the weakly adhered layer, is formed in the concave section;
- and
- the stopper is moved from the portion of the liquid channel to within the concave section by external pressing on the cover plate or the floor of the liquid channel and is housed in the concave section by the strongly adhered layer, thereby opening the liquid channel.
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 a channel formation surface of the base plate in which the liquid channel and the liquid chambers are formed,
- wherein the liquid channel device further includes a closing section for closing a portion of the liquid channel from an open mode;
- the closing section includes a stopper which is housed within a concave section formed to an inner surface of the cover plate or a floor of the liquid channel, and is maintained in the housed state within the concave section due to a weakly adhered layer;
- a strongly adhered layer, which has a larger adhesive strength than the weakly adhered layer, is formed in the concave section at a portion of the liquid channel;
- and
- the stopper moves from within the concave section to a portion of the liquid channel due to external pressing on the cover plate or the floor of the liquid channel, and is maintained at a portion of the liquid channel due to the strongly adhered layer, thereby closing the liquid channel.
