    摘要: This specification disclosed a partially closed microfluidic system and a fluid driving method. The microfluidic system is comprised of a substrate with microfluidic elements and a thin film. A feature of this structure is that the thin film is elastic and deformable. It has a single opening corresponding to a vent hole on the substrate, thus forming a partially closed microfluidic system. The substrate is designed to have several positions for micro fluid elements and deformable chambers and uses micro channels to form a complete network. Since the thin film is elastic and deformable, one is able to impose a pressure on the thin film above the deformable chambers in this partially closed microfluidic system to drive the fluid into motion. Once the pressure is released, the fluid flows back to its original configuration.

    摘要: An apparatus and a method for collecting fluid fractions. The present apparatus includes an inlet, a channel, a plurality of collectors, and an outlet. The inlet communicates with the collectors and the outlet through the channel. The collectors are disposed between the inlet and the outlet. The method for collecting the fluid fractions comprises two steps. First step, injecting the fluid in to the inlet for guiding the fluid to the outlet along the channel, wherein the fluid fills the collectors one by one due to the capillary attraction when passing through the collectors, and flows to the outlet after the collectors having been filled. Second step, injecting pressurized gas into the channel to drain the fluid fractions from fill the collectors respectively to a plurality of corresponding containers.

    摘要: Disclosed is a micro flowguide device comprising: a micro channel comprising at least one bubble trap to retard bubbles positioned in said bubble trap; an electrolytic bubble generating device to generate bubbles in said fluid by an electrolytic reaction; and a pressure source to supply a suited pressure to said fluid to pass through said micro channel; wherein said electrolytic bubble generating device causes bubbles to be generated at areas adjacent to said at least one bubble trap. Electrolytic bubbles are generated through a, localized electrolytic reaction enabled by the exposure of a set of DC-source-connected electrodes inside a conduit branch. Accumulated bubbles will be trapped and kept at several traps of the invented flowguide. When the backward pressure of trapped bubbles is rising to the level of forward pressure head, flow speed reduces to zero and channel branch is shut down.

    摘要: A collector for a negative pressure wound therapy system has a soft collecting bag with a gas-permeable unit and a liquid absorber. The collecting bag is connected to a wound-dressing unit via an inlet connecting set and is connected to a sensor assembly via a detecting connecting set. With the soft collecting bag, the collector occupies less volume. By the gas-permeable unit and the liquid absorber, the liquid and gas entering into the collecting bag quickly isolate. Moreover, multiple collectors connect in series to form a collector combination to reduce the frequency to replace the collector combination so that a longer usage time of the collector combination is available.

    摘要: A microfluidic chip with a built-in gravity-driven micropump is provided. The gravity-driven micropump comprises a winding channel, an inert fluidic material placed inside the winding channel, and a suction channel that links the winding channel to the microfluidic chip. The winding channel is for the inert fluidic material to flow in. A fixed volume of high density, inert fluidic material is placed in the winding channel to act as a micropump in the bio chip. When the microfluidic chip is placed in a declining or standing position, the inert fluidic material flows along the winding channel due to the gravity. The invention provides a simple, convenient, and robust microfluid pumping source. With the built-in micropump, this invention is free-of-pollution and saves the manufacturing cost for the pipe link between the bio chip and peripheral devices.

    摘要: The present invention relates to an autonomous microfluidic apparatus. The autonomous microfluidic apparatus is substantially a substrate having a microchannel structure arranged thereon. As a microfluid is being filled in a loading well situated upstream of the microchannel structure, the microfluid is affected by interactions between gravity, adhesive force and surface tension and thus driven to flow downstream in the microchannel structure while filling a plurality of manifolds formed in a area situated downstream of the microchannel structure, so that accurate and autonomous quantification and separation of the microfluid using the plural manifolds, each having a specific length, can be achieved and provided for biomedical inspection and analysis.

    摘要: A gravity-driven apparatus and method control the flow order of reactants in microfluidic devices which are employed in a microfluidic chip. The gravity-driven apparatus flow order control mainly comprises a plurality of reactant chambers arranged at different heights, a plurality of flow-control microchannels, and a reaction chamber having a winding collection microchannel. Each reactant chamber has an air-in vent. Each pair of neighboring flow-control microchannels has a U-shaped structure connecting the pair of neighboring flow-control microchannels. To activate the microfluidic device, the device is placed in an inclining or standing position and the air-in vents are unsealed. This method enhances the reliability of flow order control for multiple reactants. It can be built in a microfluidic chip, and does not use any actuating power or element. Therefore, it is low in energy-consumption, low in manufacturing cost and free of pollution.
