摘要： The invention refers to a microfluidic flow rate control device for controlling a flow rate of a fluid flowing through a microfluidic conduit. The control device comprises an inlet terminal for fluid input and an outlet terminal for fluid output, a microfluidic conduit communicating the inlet terminal with the outlet terminal, pumps for pumping the fluid through the conduit at a particular flow rate, valves for adjusting the flow rate of the fluid modifying their passageways, a flow sensor for measuring the flow rate within the conduit and a controller for receiving the measured flow rate, comparing it with a predefined flow rate and instructing the pumps and/or the valves to modify their pumping powers and passageways of the valves, respectively, based on the result of the comparison. The microfluidic conduit, the pumps, the flow sensor and the valves may be arranged inside the protective housing.

摘要： Disclosed herein is a microfluidic device for moving fluid through a microfluidic channel of the device. The device includes a microfluidic channel. The device further includes a positive displacement pump comprising a chamber connected to the microfluidic channel. The positive displacement pump is arranged such that when the positive displacement pump is actuated, fluid within the chamber is displaced into the microfluidic channel. The device further includes a fluid reservoir connected to the positive displacement pump to provide a source of fluid to re-fill the chamber of the positive displacement pump after the positive displacement pump has been actuated. The fluid reservoir is arranged such that fluid within the reservoir is sealed within the device.
