Micro-volume infusion pump systems and methods of making the same

摘要

An apparatus and method for volumetric micro-liter infusion of therapeutic liquids are disclosed. This portable pump system remains unobtrusive and less restrictive of patient ambulation and orientation. The present invention includes expendables, the disposability of which facilitates safe reuse of more expensive portions and is sufficiently simple for use in a home care environment. It may be designed to incorporate real-time, interactive or remote monitoring and regulation and visual or audible indication of system pressures, chemical balances and other important variables.
