A microfluidic device that can be operated by simple finger squeezing, without the aid of any extra power, i.e. electricity or a battery, present advantages for diagnostic applications. It is particularly true for diagnostic kits intended to be used in remote areas with limited access to electricity. In this paper, we describe a simple design and manufacturing of a finger pump that relies on an optimised network of check valves and squeeze pumps. The results show that the pump is capable of flowing liquid specimen with a volume of 6 mL with a finger pump priming force of around 3 N. The finger pump is intended to be used in a diagnostic kit.
