Example Embodiment
[0012] The solution of the present invention can drive the micro-membrane pump to achieve bidirectional fluid movement. In this example, a compressed gas bottle 213 is used to store positive pressure gas. The channel 203 is connected to the vacuum bottle 214 and the compressed gas cylinder 213 through three-way valves 202A, 202B, and 202C. 202A, 202B, and 202C control the positive and negative pressures in the channel 203. The compressed air 204 is used to transmit the positive pressure to the elastic sealing cap. The fluid driving process is divided into two steps: suction and discharge.
[0013] Such as Figure 2a Show the inhalation process. The three-way valve 201 connects the sealed space 206 to a negative pressure, and the chip is pressed on the chip tray 212. When the three-way valve 202A is switched to negative pressure and 202C is switched to positive pressure, the diaphragm 205A is opened and the diaphragm 205C is compressed. The corresponding fluid channel is conduct...
