Abstract
A card reading system in which electrical contacts between the assay card and the card reader are made through vertical actuation of a card interface relative to the assay card. In one embodiment, the assay card reading system comprises: (a) a card reader comprising at least one card interface, the card interface having a plurality of card interface contacts; (b) an assay card having card contacts; (c) a vertical actuation mechanism for causing relative vertical movement between the assay card and the card interface to contact at least a portion of the card interface contacts with the card contacts.
Claims30
An assay card comprising:
- first and second layers, said first layer overlaying said second layer to define a space therebetween;
- a microfluidic channel in said space;
- and
- wherein said second layer and said channel are formed in a unified body.
An assay card comprising:
- first and second layers, at least a portion of said first and second layers being spaced apart to create space therebetween;
- at least one port defined in said first layer;
- at least one microfluidic channel defined in said space and fluidically coupled to at least one port;
- and
- cell walls between said first and second layers, said cell walls defining a plurality of cells in said space.
An assay card comprising:
- a base;
- at least one microfluidic channel in or on said base for conducting a flow of a fluid, said microfluidic channel defined by sides and a width between said sides;
- and
- one or more lateral flow enhancers, each lateral flow enhancer spanning across at least a substantial portion of said width to create a lateral capillary action perpendicular to said flow, thereby causing flow laterally to said sides to fill said width of said channel before said flow of fluid continues past said lateral capillary enhancer, thereby resulting in flow across said width.
An assay card comprising:
- at least first and second layers, wherein said second layer defines at least one channel and said first layer overlays said second layer thereby defining at least one corner in said channel between said first and second layers;
- and
- one or more capillary filament disrupters disposed in said at least one corner to disrupt capillary filaments.
