Abstract

A fluid injection system including a graphical user interface, a fluid control module operatively connected to the graphical user interface, a monitoring control module provided in at least one of the graphical user interface and the fluid control module, a fluid injector operatively connected to the graphical user interface and the fluid control module, at least one fluid path set in fluid communication with the fluid control module, and a hemodynamic monitoring system operatively connected to the fluid path set and the monitoring control module. The hemodynamic monitoring system may be configured to receive electrical signals regarding pressure waves formed in medical fluid directed through the fluid path set based on a location of the fluid path set in a patient's vasculature, to convert the electrical signals to pressure wave form information, and to send the pressure wave form information to the monitoring control module.

First claim

What is claimed is:

1. A fluid injection system, comprising:
a graphical user interface;
a fluid control module operatively connected to the graphical user interface;
at least one monitoring control module operatively connected to at least one of the graphical user interface and the fluid control module;
a fluid injector operatively connected to the graphical user interface and the fluid control module;
at least one fluid path set in fluid communication with the fluid control module; and
a hemodynamic monitoring system operatively connected to the at least one fluid path set and the monitoring control module,
wherein the hemodynamic monitoring system is configured to receive electrical signals indicative of pressure waves formed in a medical fluid injected through the at least one fluid path set using the fluid injector based on a location of the at least one fluid path set in a patient's vasculature, to convert the electrical signals into pressure wave form information, and to send the pressure wave form information to the monitoring control module, and
wherein based on the pressure wave form information received from the hemodynamic monitoring system, the monitoring control module is configured to create a state logic protocol to control the fluid control module to allow an injection procedure or allow a purging or priming sequence based on the pressure wave form information.

2. The fluid injection system of claim 1 , wherein the state logic protocol created by the monitoring control module comprises:
in the event the pressure wave form information is indicative of fluid communication between the at least one fluid path set and the patient's vasculature, instructing the fluid control module to allow the injection procedure, while preventing the purging or priming sequence; and
in the event the pressure wave form information is indicative of no fluid communication between the at least one fluid path set and the patient's vasculature, instructing the fluid control module to allow the purging or priming sequence.

3. The fluid injection system of claim 1 , further comprising a transducer positioned in-line with the at least one fluid path set and operatively connected to the hemodynamic monitoring system,
wherein the transducer is configured to monitor and convert a fluid flow pressure of the medical fluid within the at least one fluid path set into the electrical signals to be sent to the hemodynamic monitoring system.

4. The fluid injection system of claim 3 , wherein the transducer comprises a pressure transducer.

5. The fluid injection system of claim 3 , further comprising a hemodynamic monitoring mechanism positioned in-line between the transducer and the hemodynamic monitoring system.

6. The fluid injection system of claim 5 , wherein the hemodynamic monitoring mechanism is configured to send pressure wave form information regarding the medical fluid in the at least one fluid path set to the monitoring control module.

7. The fluid injection system of claim 1 , wherein the graphical user interface includes a first monitoring control module and the fluid control module includes a second monitoring control module.

8. The fluid injection system of claim 1 , further comprising an automatic pressure isolation valve positioned in-line with the at least one fluid path set,
wherein the automatic pressure isolation valve is configured to control the flow of the medical fluid through the at least one fluid path set.

9. The fluid injection system of claim 1 , wherein the graphical user interface is configured to display the pressure wave form information to a user to indicate whether there is a fluctuation in a fluid flow pressure in the at least one fluid path set.

10. The fluid injection system of claim 1 , wherein:
in the event the medical fluid is being directed through the at least one fluid path set to the patient's vasculature, the graphical user display will display a first pressure wave,
in the event the medical fluid is not being directed through the at least one fluid path set to the patient's vasculature, the graphical user display will display a second pressure wave of substantially zero value, and
in the event the medical fluid is being directed through the at least one fluid path set with an amount of air, the graphical user display will display a third pressure wave that is smaller than the first pressure wave but greater than the second pressure wave.

11. The fluid injection system of claim 1 ,
wherein the graphical user interface is configured to display a visual indicator regarding a status of the system,
wherein the visual indicator is displayed as a warning indicator when a measured fluid pressure in the at least one fluid path set is greater than or equal to a possible human intra-coronary pressure range,
wherein the visual indicator is displayed as a caution indicator when the measured fluid pressure in the at least one fluid path set is greater than a normal human intra-coronary pressure range, but less than the possible human intra-coronary pressure range, and
wherein the visual indicator is displayed as a ready-to-use indicator when the measured fluid pressure in the at least one fluid path set is less than or equal to the normal human intra-coronary pressure range.

12. The fluid injection system of claim 1 , further comprising an air detector positioned in-line with the at least one fluid path set.

13. A fluid injection system, comprising:
a fluid control module;
a first fluid path set in fluid communication with the fluid control module;
a second fluid path set in fluid communication with the fluid control module;

wherein the hemodynamic monitoring system is configured to receive electrical signals indicative of pressure waves formed in a medical fluid injected through the second fluid path set based on a location of the third fluid path set in the patient's vasculature, to convert the electrical signals into pressure wave form information, and to send the pressure wave form information to the fluid control module, and
wherein based on the pressure wave form information received from the hemodynamic monitoring system, the fluid control module is configured to create a state logic protocol to allow an injection procedure or allow a purging or priming sequence using the fluid control module.
