METHOD AND APPARATUS FOR A FLUID DELIVERY SYSTEM WITH CONTROLLED FLUID FLOW RATE
First Claim
1. A medical fluid delivery system for controlling medical fluid flow for patient pain management, the system comprising:
- a fluid flow path communicating between a source and a patient;
a patient controllable interface adapted to permit patient control of fluid flow to provide a sustained flow rate in the fluid flow path that is responsive to a sensed pain level of the patient; and
a control module operably associated with the fluid flow path and the patient controllable interface, the control module being adapted to provide a first fluid flow rate in the fluid flow path and to change to the sustained flow rate in response to activation of the interface by the patient.

Abstract
The present invention includes systems and methods for medical fluid delivery. Such system may comprise a fluid flow path for communication between a fluid source and a patient. A flow valve is operatively associated with the path and movable between a first position, which allows fluid flow through the path, and a second position, which limits fluid flow through the path. A control module is operatively associated with the valve to move the valve between the first and second positions in response to a measured actual fluid flow rate in the path. Such method may comprise flowing a fluid through a fluid flow path between a portable fluid source and a patient; determining an actual fluid flow rate through the path; and changing the actual fluid flow rate in response to a difference between the actual fluid flow rate and a desired fluid flow rate. Such method may further include a plurality of settings for a desired flow rate according to a sensed pain level of the patient.
