Equivalent circuit microfluidic concentration gradient chip with simplified channel

The invention discloses an equivalent circuit microfluidic concentration gradient chip with simplified channels. The chip comprises at least two liquid inlets used for being connected with a connecting channel, a flow resistance channel, a mixing channel and an outlet channel, and is characterized in that the mixing channel adopts a novel mixing channel with a transverse elliptical bulge structureto replace a traditional linear mixing channel; therefore, the mixing effect superior to that of a traditional method can be achieved only by adopting the mixing length of one mixing period, and thewhole microfluidic concentration gradient chip structure is simplified. 本发明公开了一种简化通道的等效电路微流控浓度梯度芯片，包含至少两个进液孔，用于与连接通道、流阻通道、混合通道以及出口通道相连，其中混合通道由具有横向椭圆凸起结构的新型混合通道代替了传统的直线混合通道，从而只需采用一个混合周期的混合长度就能够实现优于传统方法的混合效果，从而简化了整个微流控浓度梯度芯片结构。
