ABSTRACT:
This invention provides a fluid pump using perforate elements and closure elements which are alternately displace and relates particularly but not exclusively to miniature fluid pumps and pumps suitable for delivery of liquid pharmaceutical formulations. In the art of miniature liquid pumps are known pumps based on peristaltic and “pump chamber” principles. (Peristaltic pumps may be used to pump fluids in general, that is, liquids or gases). Both types of pump are used in ambulatory pump products for delivery of liquid medicaments, for which application miniaturization and low weight are important attributes.
