Abstract

User interfaces for medical perfusion systems that provide oxygenation, filtering, and recirculation of blood in connection with various medical procedures are provided. In particular, user interfaces for use with blood pumps that assist in managing alarms commonly encountered during cardiopulmonary bypass surgeries are provided.

Claims

1. A method of managing an alarm condition of a perfusion system during cardiopulmonary bypass surgery, the method comprising the steps of:

providing a user interface for the perfusion system comprising a touch screen;

displaying a color coded alarm condition on the touch screen; and

displaying a color coded alarm management icon on the touch screen for managing the displayed color coded alarm condition.

2. The method of claim 1, wherein the step of displaying a color coded alarm condition on the touch screen comprises displaying one of a first, second, and third color of a color coded light bar to identify the alarm condition.

3. The method of claim 2, wherein the first, second, and third colors comprise green, yellow, and red, respectively.

4. The method of claim 3, wherein red indicates an alarm condition requiring immediate corrective action.

5. The method of claim 3, wherein yellow indicates an alarm condition requiring non-immediate corrective action.

6. The method of claim 3, wherein green indicates absence of a requirement for corrective action.

7. The method of claim 1, wherein the step of displaying a color coded alarm condition on the touch screen comprises displaying textual information to identify the alarm condition.

8. The method of claim 1, further comprising the step of displaying real time operating data indicators on the touch screen.

9. A user interface for managing an alarm condition of a perfusion system during cardiopulmonary bypass surgery, the user interface comprising:

a touch screen;

a color coded alarm condition indicator displayed on the touch screen comprising a color coded graphical portion and a color coded textual message portion for providing information related to an alarm condition;

one or more color coded alarm management icons displayed on the display screen for managing the alarm condition based on the color coded alarm condition indicator.

10. The user interface of claim 9, wherein the color coded graphical portion of the color coded alarm condition indicator comprises a horizontal bar for displaying a first, second, and third color.

11. The user interface of claim 9, further comprising real time operating data indicators displayed on the touch screen.

12. A pump console for use during cardiopulmonary bypass surgery, the pump console comprising a base unit and the user interface of claim 9, the base unit comprising one or more interfaces for controlling pump speed, monitoring flow, and communicating with the user interface.

13. The pump console of claim 9, further comprising one or more of an automated arterial line occlusion system, level detectors operatively connected to a blood reservoir, and a bubble detector system.
