Abstract

A microplegia console for controlling the delivery of cardioplegia to a patient, comprising an integrated display/touch screen for displaying cardioplegia information and patient information and allowing inputting of parameters via the display/touch screen into the console for computer-controlled perfusion of cardioplegia into the patient. The invention further comprises a method for delivery of cardioplegia to a patient, including defining and selecting a protocol from a displayed list and sequencing a series of the protocols. The invention also comprises a method for cardioplegia delivery to achieve aortic valve closure. Additionally, the invention comprises a method for activating an icon whereby, upon a first selection of the icon, displaying an indicia indicating that the icon has been first selected; and upon a second selection of the icon, activating the icon.

Claims

1. A console for controlling the delivery of cardioplegia to a patient, comprising in combination:

a computer for computer-controlled perfusion of cardioplegia into the patient according to parameters, at least some of said parameters including a set of protocols, said computer then sequencing said protocols in a specific order fora particular patient and to deliver cardioplegia to the patient in accordance with said protocols in said sequence,

an integrated display/touch screen for displaying cardioplegia information and information about the patient and allowing inputting of parameters, said protocols and said sequence via the display/touch screen into the console for computer-controlled perfusion of cardioplegia into the patient in accordance with said protocols in said sequence;

a flow knob allowing manual control the cardioplegia flow rate, said manual control via said flow knob taking precedence over any in-process computer-controlled cardioplegia perfusion into the patient by suspending any in-process perfusion of cardioplegia into the patient in accordance with said protocols in said sequence, whereby manual control of the cardioplegia perfusion into the patient resumes, and

an interface cable including an interface operatively connected between the console and a cardioplegia pump.

2. The console as set forth in claim 1, wherein the pump provides electrical power to the console via said interface cable such that the console powered on when the pump is powered on.

3. The console as set forth in claim 1, further including an electrocardiogram input allowing an electrocardiogram waveform to be displayed on the display/touch screen.

4. The console as set forth in claim 1, further including one or more of a an interface port to export or import data to or from an external storage media, a printer port for network or local printing, a communication port for connectivity communications.

5. The console as set forth in claim 1, further including a switch input for a switch that boots the console into a flash loader mode.

6. The console as set forth in claim 5, wherein said switch comprises a reed switch concealed within a housing of the console, said reed switch including contacts that are closed when a magnet is moved in close proximity to said reed switch.

7. The console as set forth in claim 1, wherein said display/touch screen comprises a graphical user interface.

8. The console as set forth in claim 7, wherein said display/touch screen displays a Select Step allowing selection of a Case Manager Step, a New Case Setup Step, a Resume Case Step or a Menu Step.

9. The console as set forth in claim 8, wherein said Case Manager Step allows setup of said protocols and said sequence in said specific order.

10. The console as set forth in claim 8, wherein said New Case Setup Step allows setup for a new patient based upon one or more of User Defaults, a Previous Case, an Existing Protocol or Existing Sequence.

11. The console as set forth in claim 8, wherein said New Case Setup Screen includes one or more of User Defaults, An Existing Protocol, Previous Case Parameters and An Existing Sequence active icons corresponding to the User Defaults Step, Previous Case Step, Existing Protocol Step and Existing Sequence Step.

12. The console as set forth in claim 11, wherein selection of said User Default active icon displays Review/Modify Parameter screens, which is scrolled through to display the factory-predefined user default parameters.

13. The console as set forth in claim 12, wherein the Review/Modify Parameter screens includes a Prime active icon corresponding to the Prime Step allowing transfer to the Prime Step in preparation for delivering cardioplegia to the patient.

14. The console as set forth in claim 7, wherein said display/touch screen displays a Prime Step that when selected primes the pump to begin perfusion.

15. The console as set forth in claim 7, wherein said display/touch screen displays a Home Screen Step that when selected allows monitoring the computer-controlled delivery of cardioplegia to the patient.

16. The console as set forth in claim 15, wherein said Home Screen Step allows manual pause or stopping of the delivery of cardioplegia to the patient in which case a Resume Case Step then allows subsequent resumption of delivery of cardioplegia to the patient.

17. The console as set forth in claim 15, wherein said Home Screen Step allows return to a Case Manager Step to temporarily change previously-setup protocol or sequencing parameters.

18. The console as set forth in claim 7, wherein, while either in the Select Screen Step or while in the Home Screen Step, a Menu Screen Step is selected to perform various administrative functions.

19. The console as set forth in claim 7, wherein said display/touch screen displays active or passive icons for appropriate controls and parameters relevant to a step being performed, the active icons representing such controls and parameters being selectable as desired for manipulation of the parameters or navigation to previous or succeeding screens.

20. The console as set forth in claim 7, wherein at the conclusion of delivery of cardioplegia to the patient, the parameters used are stored in memory as the Previous Case Parameters.

21. The console as set forth in claim 20, wherein selection of the Previous Case Parameters displays the previous-case parameters in the Review/Modify Parameter screens review or modification, and when completed, transfers to the Prime Step in preparation for delivering cardioplegia to the patient.

22. The console as set forth in claim 7, further including predefining a collection of parameters, labeling them and storing in memory as Existing Protocols for later use via Case Manager.

23. The console as set forth in claim 22, wherein in lieu of using User Default or Previous Case parameters respectively corresponding to the User Default Step or Previous Case Step, an Existing Protocol may be selected in the New Case Setup screen corresponding to the Existing Protocol Step, whereupon a listing of the predefined Existing Protocols is displayed.

24. The console as set forth in claim 23, wherein upon selection of one of the Existing Protocols, its predefined parameters are displayed the Review/Modify Parameter screens for review or modification, and when completed, transfer to the Prime Step.

25. The console as set forth in claim 24, further including sequencing a series of Existing Protocols to be used in sequence, labeling and storage in memory as Sequences for later use via Case Manager.

26. The console as set forth in claim 25, wherein upon selection of one of the Existing Sequences listed in the New Case Setup screen, the selected Existing Sequence'"'"'s sequence of Protocols are displayed for review or modification and when completed, transferred to the Prime Step.

27. The console as set forth in claim 26, further including a play icon for initiating the Sequence.

28. The console as set forth in claim 27, further including pause and stop icon to pause or stop the running of the Sequence.

29. The console as set forth in claim 28, further including a skip icon for skipping one or more of the Protocols of the Sequence.

30. The console as set forth in claim 7, further including a data viewer.

31. The console as set forth in claim 7, further including a training simulator.
