  • Liquid delivery device
    Patent number: 7431050
    Abstract: A fluid delivery device is provided which comprises a microchannel device for cutting out a certain amount of a sample from a micorochannel by controlling a valve opening. The fluid delivery device has a valve for controlling a flow of a fluid, comprising a flow channel for the fluid, and a valve in the flow channel, wherein the valve operates in accordance with a pressure difference between the upstream side and downstream side of the valve caused by the flow of the fluid through the flow channel, allowing the fluid to flow when the pressure difference is lower than a prescribed value P0, and intercepting the fluid not to flow when the pressure difference is P0 or more.
    Type: Grant

  • Fluid-conveying apparatus and method for conveying fluid by using the same
    Publication number: 20060115382
    Abstract: A fluid-conveying apparatus conveys fluid using a channel for the fluid to flow. The apparatus includes a pressure-generating device for generating pressure for conveying the fluid, a plurality of processing areas for processing the fluid, a valve which is disposed between the processing areas and controls the fluid flow, and a pressure-relieving device for relieving the pressure in the channel.
