Abstract

The present set of embodiments relate to a system, method, and apparatus controlling a cell culture media mixing system. The control system includes an integrated control unit capable of controlling a broad ranges of peripheral devices commonly used in bioproduction through a graphical user interface displayed on a touch sensitive screen. The bioproduction system is designed to be highly customizable through process modification and recipe creation by user with little or no knowledge of programming and is capable of controlling a wide variety of devices using a single unit. The bioproduction system allows for auto-detection, auto-calibration, and automatic of device related processes into a bioproduction workflow.

First claim

What is claimed is:

1. A method of initializing a cell culture media mixing process for a mixer, comprising:
providing a cell culture media mixing system having a compartment, wherein the compartment includes a mixing element, the compartment configured to contain a fluid and nutrients for cell growth;
connecting a device to an integrated control unit, wherein the device is in physical communication with the cell culture media mixing system and in electronic communication with the integrated control unit;
displaying a bioproduction workspace screen at a display of the integrated control unit, the bioproduction workspace screen graphically representing the cell culture media mixing process, the bioproduction workspace screen including a bioprocess module graphically representing a process relating to the device;
wherein the integrated control unit automatically detects a property of the device; and
wherein the integrated control unit automatically orders the process relating to the device within a process workflow based on the property.

2. The method of claim 1 wherein a second bioprocess module is a recipe creation module.

3. The method of claim 2 further comprising the step of creating a recipe, wherein a step within the recipe includes adding a bolus to the fluid.

4. The method of claim 1 further comprising the step of automatically ordering the bioprocess module within a set of bioprocess modules on the bioproduction workspace screen based on the process workflow, wherein the process workflow is stored on a memory.

5. The method of claim 4 further comprising the step of selecting a process workflow from a set of process workflows based on the fluid being mixed within the compartment.

6. The method of claim 5 further comprising the step of selecting a process workflow from a set of process workflows based on a biological process occurring within the compartment.

7. The method of claim 1 wherein the bioproduction workspace screen and the bioprocess module are displayed on a touch sensitive screen of the integrated control unit.

8. The method of claim 7 wherein a user can select a bioprocess module by touching the touch sensitive screen to deactivate the process relating to the device, wherein the bioprocess module is updated to indicate that the process relating to the device is inactive.

9. The method of claim 7 wherein a user can select a module by touching the touch sensitive screen to activate the process relating to the device, wherein the module is updated to indicate that the process relating to the device is active.

10. The method of claim 7 wherein a user can select a bioprocess module by touching the touch sensitive screen to re-order the bioprocess module within the bioproduction workspace screen and a corresponding process is re-ordered within the process workflow.

11. The method of claim 10 wherein the bioprocess module and the corresponding process are re-ordered while the process workflow is active.

12. A method of configuring a cell culture media mixing process, comprising:
providing an integrated control unit including a display and a set of ports;
displaying a bioproduction workspace screen on the display, the bioproduction workspace screen graphically representing the cell culture media mixing process;
providing a mixing system including a device;
connecting the device to a port within the set of ports; and
automatically activating the device and displaying a bioprocess module within the bioproduction workspace screen on the display upon connection of the device to the port, the bioprocess module graphically representing a process relating to the device.

13. The method of claim 12 wherein the integrated control unit automatically calibrates the device upon connection of the device to the port.

14. The method of claim 13 wherein the device is a load cell and calibrating further includes the step of setting a tare value for the load cell.

15. The method of claim 13 further comprising the step of selecting a control setpoint and an action.

16. The method of claim 15 further comprising the step of selecting a tolerance for the setpoint and a duration.

17. The method of claim 16 further comprising the step of executing the action when the tolerance is exceeded for the duration.

18. The method of claim 17 wherein the action includes activating the device.

19. The method of claim 16 further comprising the step of activating an alarm when the tolerance is exceeded.

20. The method of claim 16 further comprising the step of activating an alarm when the tolerance is exceeded for the duration.

21. The method of claim 12 wherein the bioproduction workspace screen includes a tab.

22. The method of claim 21 further comprising the step of selecting the tab and displaying a list of active processes.

23. The method of claim 22 further comprising the step of selecting an active process from the list and subsequently navigating to a details screen.

24. A method of configuring a bioproduction mixing process, comprising:
providing an integrated control unit including an interactive display and a set of ports;
providing a cell culture media mixing system including a rigid housing and a flexible compartment configured to conform to an interior of the rigid housing, wherein the flexible compartment includes a mixing element and an interior of the flexible compartment is configured to contain a fluid and nutrients;
connecting a sensor to one of the ports, wherein the sensor is in communication with the interior of the flexible compartment;
automatically displaying a bioprocess module graphically representing a process relating to that represents the sensor on the interactive display upon connection of the sensor to the port; and
arranging a set of bioprocess modules within a bioproduction workspace screen on the interactive display based on an identification of the sensor, the bioproduction workspace screen graphically representing the bioproduction mixing process, wherein the order of the displayed bioprocess modules correlates to the order in which a set of processes will take place within a process workflow.

25. The method of claim 24 further comprising the step of starting a mixing process within the interior of the flexible compartment using the mixing element to mix the fluid.

26. The method of claim 24 further comprising the step of re-ordering the set of bioprocess modules and their associated processes within the bioproduction workspace representing the process workflow based on a user's selection.

27. The method of claim 24 further comprising the step of indicating within a second bioprocess module that a process is not scheduled to be used within the process workflow.
