Abstract

A configurable fluid delivery system and methods for its use are disclosed. The system may include one or more control units, fluid delivery units, fluid actuator units, and disposable units. Data sources and sensors on each of the delivery units, actuator units, and disposable units may provide data to the control unit, thereby identifying the components along with the manner in which they may be configured. The control unit may notify a user regarding the status of any one or more of the delivery, actuator, and disposable units to indicate their appropriateness for delivering a fluid according to one or more selected procedures and protocols. Also disclosed are methods by which the configurable fluid delivery system may provide data to a user to assist the user in assembling and testing a particular configuration of the fluid delivery system for a specific use.

First claim

1 - 23 . (canceled)

24 . A fluid delivery system for controlled delivery of a fluid to a recipient, the fluid delivery system comprising:
a fluid delivery unit for pressurizing and enabling delivery of the fluid to the recipient, the fluid being acquired from a source of the fluid via outlet thereof; a high crack pressure valve having an inlet, an outlet and a moveable element, the inlet being adapted to receive the fluid pressurized by the fluid delivery unit and the moveable element being adapted to transmit from the outlet the fluid received from the inlet when the fluid at the inlet reaches a pressure at least equal to a crack pressure threshold of the high crack pressure valve; and a fluid path element for receiving the fluid from the outlet of the high crack pressure valve and conveying the fluid to any remaining system components for ultimately delivery to the recipient.

25 . The fluid delivery system of claim 24 further comprising a control unit to control delivery of the fluid wherein the control unit controls at least one of the fluid delivery unit and the high crack pressure valve.

26 . The fluid delivery system of claim 25 , wherein the control unit controls the high crack pressure valve.

27 . The fluid delivery system of claim 25 , wherein the high pressure crack valve is an on-off valve and the control unit rapidly opens and closes the high pressure crack valve to maintain the pressure in the system.

28 . The fluid delivery system of claim 24 , wherein the high crack pressure valve is a spool type high pressure crack valve having a resistive force element selected from a spring and a pressurized bladder.
