流体控制装置
摘要：
本发明公开一种流体控制装置，其包含流体岐管部、旋转阀定子、旋转阀转子及双驱动单元。流体岐管部包含与样品反应单元连接的微管道及与流体源连接的流体源输入管道。当旋转阀转子转至预设位置时，流体源输入管道经由旋转阀定子的穿孔及旋转阀转子的沟槽而与微管道连接。第一驱动单元驱动旋转阀转子的转动。第二驱动单元驱动旋转阀转子或旋转阀定子的移动，以调整旋转阀转子与旋转阀定子的距离，使得当旋转阀转子转动时，旋转阀转子与旋转阀定子之间具有间隙，且当旋转阀转子转动至预设位置后，旋转阀转子紧贴于旋转阀定子。
摘要（英）：

A fluid control device is disclosed and includes a fluid manifold, a valve stator, a valve rotor and dual driving units. The fluid manifold includes microchannels connected with a sample reaction unitand fluid input channels connected with fluid sources. When the valve rotor is rotated to different positions, the fluid input channel is connected with the microchannels via through holes of the valve stator and a groove of the valve rotor. The first driving unit drives a rotation of the valve rotor. The second driving unit drives a motion of the valve rotor or the valve stator to adjust a distance between the valve rotor and the valve stator, so that when the valve rotor is rotating, the valve rotor and the valve stator are separated by a gap, and after the valve rotor is rotated to a predetermined position, the valve rotor is tightly contacted the valve stator.
