Abstract：
 The invention relates to a microflow control chip system for flow type cell detection, it character lies in: it includes microflow control chip driven by gravity, a laser focusing induced fluorescence detecting system which can be connected to a computer, charge coupling detector and high voltage power; the primary channel and assistant channel of the microflow chip are arranged on the top surface of the microflow chip, and which are connected to the sample pool and buffer liquid pool on the microflow control chip, three cell collectors are on the end of the primary channels, the microflow control chip is fixed on a base vertically, the focusing laser induced fluorescence detecting system is at one side of the microflow control chip, and its detecting area is at the middle or lower part of the primary channel, the charge coupling detector is at another side of the microflow control chip, the output of the high voltage powder is positive and negative voltage which are conducted to the cell collectors are two sides of the microflow control chip. The structure is simple, and the sample and reagent quantity can be reduced.
