摘要：A device () for generating a pulsatile fluid drug flow comprises a housing ()containing an expandable-contractible chamber () having an inlet () and an outlet (), avalve () associated with the outlet () which is actuated by the expansion and contraction of

the chamber (), and means () for biasing the chamber () to its contracted state. When theinlet () is connected to a pressurised fluid drug supply the chamber () is expanded by thedrug, and this expansion of the chamber () actuates the valve () to open, thereby allowingrelease of the drug from the chamber (), following which the chamber () contracts underthe influence of the biasing means (), this contraction in turn actuating the valve () to closethereby allowing the chamber () to refill. By this mechanism, a constant supply of liquid,such as from an osmotic or elastomeric drug delivery pump, can be converted to apulsatile flow, which may provide a more suitable delivery of certain drugs.
