Abstract

The present invention discloses a micro check valve (100) for use in controlling the flow of fluid across a channel (160) in a micro-fluidic system, said valve (100) housed within a valve seat (140) and comprising a polygonal mass (110) connected to a base (120) through a resilient means (130). The mass (110) is a polygonal member with a predetermined thickness having a first side surface (101) exposed to the entry of fluid flowing in the channel (160), a second side surface (102) distanced apart and parallel to the first side surface (101 ), and having a longer length than the first side surface (101 ), a third side surface (103) and a fourth side surface (104) adjoining both ends of the first side surface (101) and the second side surface (102), said third side surface (103) and fourth side surface {104) disposed with a plurality of protruding dimples (106). Elastic deformation of the resilient means (130) due to pressure exerted on the mass (110) controls the flow of fluid across the channel (160), whereby establishment of a sealing contact between the mass (110) and the valve seat (140) blocks the flow of fluid across the channel (160) and a release of sealing contact between the mass (110) and the valve seat (140) allows the flow of fluid across the channel (160).
