Abstract
Embodiments disclosed herein provide microfluidic device components that may be used independently as valves, pumps, filters or as storage containers (flasks) with integrated valve and pump mechanisms. The components described herein may be integrated into multiple microfluidic device designs, including centrifugal and non-centrifugal microfluidic devices (“linear microfluidic devices”). The components may be used to store and/or dispense and/or move various reagents that may be employed on a microfluidic device to carry out any of a number of chemical and biological reactions and assays that may be done on such devices.
Claims23
A device component, consisting of:
- one or more layers of an elastic sheath and/or flexible sheath material;
- a core material with one or more internal compartments and one or more apertures in a side wall of the core material that connects the internal compartment to an outer surface of the core material and that is press fit within the one or more layers of an elastic sheath and/or flexible sheath material,
- wherein the elastic sheath and/or flexible sheath-material is configured to deform at the one or more apertures and unseal the one or more apertures upon application of an external force to the elastic sheath and/or flexible sheath material, and to recover and reseal the one or more apertures upon removal of the external force;
- and
- wherein the one or more internal compartments is configured to proportionally release reagents stored in the one or more internal compartments via the one or more apertures when unsealed.
A device filter comprising:
- one or more layers of an elastic sheath and/or flexible sheath material;
- a core material with two or more internal compartments, each compartment separated by a porous filter material, and one or more apertures in a side wall of the core material that connects at least one of the internal compartments to an outer surface of the core material, the core material press fit within the one or more layers of an elastic sheath and/or flexible sheath material.
