DIALYSIS MACHINES WITH TOUCH SCREEN USER INTERFACE

摘要

A user interface (12) for a medical instrument such as a dialysis machine (1 0) is described which uses both a touch screen (14) and hard keys (16, 18 and 2 0) off of the touch screen (14) to effectuate a change in a parameter associate d with the operation of the machine (10). The user interface (12) is connected to extracorporeal circuit (24), mounted above lower cabinet (22) of dialysis machine (10). After the user selects a new parametric value on the touch screen (12), the user presses a hard key (16, 18 or 20) to implement a verification routine to insure that the entered parameter is appropriate for a machine's (10), patient's treatment and the display on the touch screen (14) . If the verification procedure ends in a positive result, the user is prompte d to press a second hard key (16, 18 or 20) to confirm the change, causing an additional verification check to be performed.
