| 摘要 |
A device for controlling the flow of fluid comprising a cooled thermal mass, a cradle comprising a channel mounted on a thermal bridge, said thermal bridge being in thermal communication with said cooled thermal mass, and said channel being capable of receiving a fluidic conduit, said fluidic conduit capable of transporting one or more fluids, freezing the fluids contained therein at a low temperature to restrict flow; a heat element, proximal to said cradle, for applying heat to said fluidic conduit to thaw fluids therein to allow flow; wherein said thermal bridge has one or more voids, such that the cross-section available for heat flow between said heat element and said cooled thermal mass is reduced. |
