INFORMATION ENTRY VALIDATION SYSTEM AND METHOD FOR A DIALYSIS MACHINE

摘要

Information is entered and validated by the operator of a dialysis machine (30) by converting (230) the entered information into a first form using a first conversion relationship such as ASCII. The information in the first form is next converted (238) into a second form using a second conversion relationship, such as floating point numeric. Thereafter the information in the second form is converted (244) back to the first form using the first conversion relationship. The information in the first form which resulted from the third conversion (244) is displayed (246 and 248) for acceptance for rejection by the operator. Displaying the information resulting from sequential multiple conversions (230, 238, and 244) assures an opportunity for the operator to evaluate the entries for accuracy. Re-display of the previously entered information repeatedly presents the operator with an opportunity to recognize human-induced errors.
