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

What is claimed is:

1. A fluid delivery system for controlled delivery of a fluid to a recipient, the fluid delivery system comprising:
a fluid delivery unit comprising a syringe for pressurizing and enabling delivery of the fluid to the recipient;
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 syringe, wherein the moveable element is adapted to transmit to 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, the crack pressure threshold being a pressure above or near a maximum programmed operating pressure of the fluid delivery system to prevent fluid flow from the syringe due to capacitance swell of the syringe when pressurized;
a first 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 ultimate delivery to the recipient;
a controller to control the fluid delivery unit and to control the crack pressure threshold of the high crack pressure valve; and
a fluid junction for receiving fluid from the outlet of the high crack pressure valve and for receiving fluid from a second fluid path element configured to receive a second pressurized fluid from a second syringe of the fluid delivery unit;
wherein a pressure of fluid at the outlet of the high crack pressure valve has little or no effect on movement of the moveable element, and
wherein the maximum programmed operating pressure is programmed into the controller.

2. The fluid delivery system of claim 1 , wherein the pressure of the fluid at the inlet opens and closes the high crack pressure valve to maintain the pressure in the system.

3. The fluid delivery system of claim 1 , wherein the high crack pressure valve prevents fluid flow from the outlet to the inlet.

4. The fluid delivery system of claim 1 , wherein a rear portion of the moveable element is isolated from the fluid.

5. A fluid delivery system for controlled delivery of fluid to a recipient, the fluid delivery system comprising:
a fluid delivery unit comprising a syringe for pressurizing and enabling delivery of the fluid to the recipient;
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 syringe, wherein the moveable element is adapted to transmit to 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, the crack pressure threshold being a pressure above or near a maximum programmed operating pressure of the fluid delivery system to prevent fluid flow from the syringe due to capacitance swell of the syringe when pressurized;
a first 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 ultimate delivery to the recipient;
a controller to control the fluid delivery unit; and
a fluid junction for receiving fluid from the outlet of the high crack pressure valve and for receiving fluid from a second fluid path element configured to receive a second pressurized fluid from a second syringe of the fluid delivery unit;
wherein a pressure of fluid at the outlet of the high crack pressure valve has little or no effect on movement of the moveable element,
wherein the maximum programmed operating pressure is programmed into the controller, and
wherein the high crack pressure valve further comprises at least one sealing surface and a force actuator selected from the group consisting of a passive force actuator, a manually adjustable force actuator, and a controllable force actuator.

6. The fluid delivery system of claim 5 , wherein the high crack pressure valve is a spool type high crack pressure valve and wherein the moveable element comprises an internal sliding element that can block fluid flow.

7. The fluid delivery system of claim 6 , wherein the force actuator comprises a resistive force element to resist movement of the internal sliding element.

8. The fluid delivery system of claim 7 , wherein the resistive force element is selected from a spring, a pressurized bladder, an elastomer, an electromechanical actuator, and a magnetic force actuator.

9. The fluid delivery system of claim 5 , wherein the high crack pressure valve comprises a compressible tubing comprising the inlet and the outlet and wherein the moveable element is configured to provide an external pressure to compress the tube.

10. The fluid delivery system of claim 9 , wherein the external pressure produces a force of compression on the tube by the force actuator, wherein the force actuator comprises one of a spring, a bladder, an electromechanical actuator and a magnetic actuator, and wherein the force of compression is counteracted when the fluid at the inlet reaches a pressure at least equal to the crack pressure threshold.

11. The fluid delivery system of claim 5 , wherein the force actuator is a passive force actuator selected from a spring and a bladder.

12. The fluid delivery system of claim 5 , wherein the force actuator is a manually adjustable force actuator comprising a screw compressing a spring, wherein the screw controls a force of compression of the spring.

13. The fluid delivery system of claim 5 , wherein the force actuator is a controllable force actuator controlled by the controller, wherein the controllable force actuator is a solenoid driven spring compression, a hydraulic driven spring compression, a pneumatic driven spring compression, or a motor driven spring compression.

14. The fluid delivery system of claim 5 , wherein a rear portion of the moveable element is isolated from the fluid.
