为了制作高压微泵，研究了一种采用被动式止回阀的微型泵，并研制了一种新型的微型止回阀。它具有由硅橡胶浮子和通孔组成的简单结构。该阀的反向流动阻力约为10 atm min/μl，在施加的压力为0.5 atm时，正向与反向流动比约为1000。该阀可应用于高压微型泵，用于高达至少1个大气压的压力。
To fabricate a high-pressure micropump, a diaphragm-type pump using passive check valves has been studied and a novel micro check valve developed. It has a simple structure consisting of a silicone rubber float and a through-hole. The reverse flow resistance of this valve is about 10 atm min/μl and the forward-to-reverse flow ratio is about 1000 at an applied pressure of 0.5 atm. This valve can be applied to the high-pressure micropump for pressures up to at least 1 atm.
