摘要:
A micropump according to the invention uses axially oriented pistons to definea pump volume.Translating the pistons axially with respect to each other within a pumphousing draws ametered amount of fluid into the pump volume from a reservoir port fordelivery to a cannulaport when the space is collapsed. Radially situated seals on the pistonscooperate with the axialmovement to close off and open the cannula port and the reservoir portrespectively atdifferent positions of the piston stroke.
