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.

Description

technical field [0001] The present invention generally relates to a parenteral medical fluid delivery system and methods of use thereof. Background technique [0002] Various types of medical fluids are commonly administered or infused parenterally to patients for therapy, pain management, and / or other reasons. Liquids or fluids may include pharmaceutically active agents or anesthetics, saline, nutritional fluids, or other fluids. The infusion system delivers fluid to a patient through a disposable flow path for a selected period of time according to a programmed flow rate or flow profile. Although typically this infusion is performed in a hospital setting where the patient is essentially confined to a bed, it may be more convenient to perform the infusion while the patient remains ambulatory if the infusion is to be performed over an extended period of time. [0003] In ambulatory and other medical fluid infusion systems, it is desirable that the flow rate be accurate thr...
