Abstract

A medical fluid processing device for processing blood or other fluids includes a plurality of hardware elements that perform specific functions. Different processing procedures are achieved by performing the specific functions in appropriately arranged sequences and combinations. A user accessible menu permits user selection of the desired processing procedure. A software implemented "virtual" interface generates appropriate hardware commands for actuating the hardware elements as needed to achieve the desired processing procedure. A dual region, user-accessible screen provides user interaction with the processing device. The "virtual" interface provides positive control over the individual hardware elements in combination with sufficient system flexibility to achieve useful interactivity with the processing device operator.

Claims

1. A processing system for processing fluids for medical purposes including a user interactive interface, the system comprising

an array of hardware elements,

control means for actuating the hardware elements to carry out a predetermined fluid processing procedure, the control means including an output for transmitting a processing status value that changes over time as the hardware elements carry out the fluid processing procedure,

an interface screen having a first display region and a second display region spaced and distinct from the first display region,

an interface manager communicating with the interface screen and the control means output, the interface manager including

means for generating a first display including a first touch activated field and another field displaying the changing processing status value in response to the control means output,

means for generating a second display different than the first display,

means for generating a third display different than the first and second display,

means for showing the first display in the first region to display changes in the processing status value in response to the control means output,

means for showing the second display in the second region while simultaneously keeping the first display showing in the first region to display changes in the processing status value, and

means responsive to touching the first touch activated field in the first display while the second display is showing in the second region for thereafter blanking the second display and showing the third display in the second region while simultaneously keeping the first display showing in the first region to display changes in the processing status value.

2. A system according to claim 1

wherein the means for generating the first display includes means for generating a second touch activated field in the first display different than the first touch activated field, and

wherein the interface manager further includes means responsive to touching the second touch activated field in the first display while the third display is showing in the second region for thereafter blanking the third display and showing the second display in the second region while simultaneously keeping the first display showing in the first region to display changes in the processing status value.

3. A system according to claim 1

wherein the means for generating the first display including means for generating a second touch activated field in the first display different than the first touch activated field, and

wherein the interface manager includes means for showing the second display in the second region whenever the second touch activated field is touched while simultaneously keeping the first display showing in the first region to display changes in the processing status value.

4. A whole blood processing system including

an array of hardware elements, and

control means for actuating the hardware elements to carry out a predetermined fluid processing procedure, the control means including

first program means for defining the functional steps of the procedure and generating prescribed abstract function selection commands based upon the defined steps,

second program means communicating with the first program means for generating specific hardware selection commands in response to receiving the function selection commands generated by the first program means, and

peripheral control means communicating with the hardware elements and with the second program means, and not with the first program means, for actuating the hardware elements in response to receiving the hardware selection commands generated by the second program means.

5. A system for specifying a user interface in a whole blood processing apparatus, the system comprising

an interface device,

first program means for generating prescribed abstract display selection commands,

second program means communicating with the first program means for generating specific format control commands in response to receiving the display selection commands generated by the first program means, and

interface control means communicating with the interface device and with the second program means, and not with the first program means, for creating a display on the interface device in response to receiving the format control commands generated by the second program means.

6. A system according to claim 5

wherein the display created by the interface control means includes at least one touch activated field,

wherein the interface control means is operative for generating a selected touch indicator code in response to touching the touch activated field for transmittal to the second program means,

wherein the second program means is operative for transmitting a function control code to the first programming means in response to receipt of the selected touch indicator code, and

wherein the first programming means includes means for generating output based upon the function control code.
