Abstract

In one aspect of the invention, the fluidic device includes a fluidic chip includes a body having a first surface and an opposite, second surface, one or more channels formed in the body in fluidic communications with input ports and output ports for transferring one or more fluids between the input ports and the output ports, and a fluidic chip registration means formed on the first surface for aligning the fluidic chip with a support structure; and an actuator configured to engage with the one or more channels at the second surface of the body for selectively and individually transferring the one or more fluids through the one or more channels from at least one of the input ports to at least one of the output ports at desired flowrates.

First claim

What is claimed is:

1. A fluidic device, comprising:
a fluidic chip comprising a body having a first surface and an opposite, second surface, one or more channels formed in the body in fluidic communications with input ports and output ports for transferring one or more fluids between the input ports and the output ports, and a fluidic chip registration means formed on the first surface for aligning the fluidic chip with a support structure; and
an actuator configured to engage with the one or more channels at the second surface of the body for selectively and individually transferring the one or more fluids through the one or more channels from at least one of the input ports to at least one of the output ports at desired flowrates, such that flow directions of the one or more fluids through the one or more channels are reversible,
wherein the fluidic chip registration means is configured such that the fluidic chip is allowed for multiple fluidic chip orientations while maintaining automatic and precise mechanical alignment to the support structure.

2. The fluidic device of claim 1 , further comprising a motor to operably drive the actuator to be activated or deactivated.

3. The fluidic device of claim 1 , wherein the body of the fluidic chip comprises a first layer and a second layer, each layer having a first surface and an opposite, second surface, wherein the one or more channels are grooved on a first surface of the second layer, a second surface of the first layer is planar and bonded to the first surface of the second layer to seal an open side of the one or more channels in the first surface of the second layer, and the second layer is elastomeric, such that compression of the actuator on a second surface of the second layer causes at least one of the one or more channels in the second layer to be occluded, wherein the first and second surfaces of the body are coincident with the first surface of the first layer and the second surface of the second layer, respectively.

4. The fluidic device of claim 1 , wherein the fluidic chip is configured such that one or more plug-in accessories are addable in or removable from the fluidic chip, wherein the one or more plug-in accessories comprise capacitors, adjustable fluidic resistors, electrical or electrochemical sensors, photosensors for detecting or tracking bubbles for either bubble detection or for determining flow rates, flowmeters, manifolds, overpressure relief (blow-off) valves, check valves, bubble traps, injection ports, bioreactors, or a combination of them.

5. A fluidic device, comprising:
a fluidic chip comprising a body having a first surface and an opposite, second surface, one or more channels formed in the body in fluidic communications with input ports and output ports for transferring one or more fluids between the input ports and the output ports, and a fluidic chip registration means formed on the first surface for aligning the fluidic chip with a support structure; and
an actuator configured to engage with the one or more channels at the second surface of the body for selectively and individually transferring the one or more fluids through the one or more channels from at least one of the input ports to at least one of the output ports at desired flowrates,
wherein the fluidic chip registration means comprises at least one protrusion that is protruded from the first surface of the body.

6. The fluidic device of claim 5 , wherein the fluidic chip registration means is configured such that the fluidic chip is allowed for multiple fluidic chip orientations while maintaining automatic and precise mechanical alignment to the support structure.

7. The fluidic device of claim 5 , wherein the least one protrusion is configured to fluidically communicate the one or more channels with interface ports that allow connection of external tubing to the fluidic chip through a base plate.

8. A fluidic device, comprising:
a fluidic chip comprising a body having a first surface and an opposite, second surface, one or more channels formed in the body in fluidic communications with input ports and output ports for transferring one or more fluids between the input ports and the output ports, and a fluidic chip registration means formed on the first surface for aligning the fluidic chip with a support structure; and
an actuator configured to engage with the one or more channels at the second surface of the body for selectively and individually transferring the one or more fluids through the one or more channels from at least one of the input ports to at least one of the output ports at desired flowrates,
wherein the fluidic chip is a circular through-plate fluidic chip.

9. The fluidic device of claim 8 , being a rotary planar valve (RPV) comprising a multi-channel valve, a manifold valve, or a multi-throw valve.

10. The fluidic device of claim 9 , wherein each of the one or more channels comprises one or more sub-channels connected to one or more input ports and one or more outputs, wherein all the sub-channels of the one or more channels are spaced-apart in the radial channel configuration.

11. The fluidic device of claim 10 , wherein the actuator comprises
a cage defining a plurality of spaced-apart openings;
a plurality of pop-up members, each pop-up member retained in a respective opening of the cage and being vertically movable therein; and
a drivehead having a surface and at least one recess formed on the surface,
wherein the cage is placed on the second surface of the fluidic chip to constrain each pop-up member in a position immediately on a respective sub-channel, such that when a pop-up member is pressed into the second surface of the fluidic chip, a sub-channel that is immediately on the pop-up member is compressed, otherwise, said sub-channel is uncompressed; and
wherein the drivehead is rotatably engaged with the cage such that as the drivehead rotates at a position, any selected pop-up members positioned in the at least one recess arise to create open sub-channels corresponding to the selected pop-up members, thereby selectively unoccluding or occluding fluid flows through desired sub-channels.

12. The fluidic device of claim 11 , wherein the at least one recess comprises a plurality of tangential ovoid recesses.

13. The fluidic device of claim 12 , wherein the plurality of tangential ovoid recesses is configured to ensure that there is no “off” position for the plurality of pop-up members while switching from one input port to another input port where both input sub-channels connected to said two input ports are closed at the same time.

14. The fluidic device of claim 11 , wherein the fluidic chip and the actuator are configured such that there are actuated balls that open and close channels upon which they reside, unactuated balls underneath which channels are always closed, and absent balls underneath which channels are always open, thereby partitioning the valve into a plurality of independent fluid-containing regions separated by the unactuated balls, each region having its own inlet/outlet ports, a group of channels, and actuated balls such that by a selection of the actuated balls, flows to or from the ports within said region are dynamically controllable, which allowing a plurality of isolated fluidic circuits to exist on a single chip.

15. A fluidic device, comprising:
a fluidic chip comprising a body having a first surface and an opposite, second surface, one or more channels formed in the body in fluidic communications with input ports and output ports for transferring one or more fluids between the input ports and the output ports, and a flu
