The medical device has a control unit, which is equipped for automatic start-up of the medical device at a predetermined point in time and for checking on whether, after start-up of the medical device, a predetermined event has occurred, and has a display screen for display of information when the check reveals that the event has not occurred. Furthermore, a corresponding process for user-friendly operation is described. ## Claims ### Claim 1 A medical device, comprising a control unit equipped for automatically starting the medical device at a predetermined point in time and, after starting the medical device, checking on whether a predetermined, automatically carried-out event has occurred before starting the medical device, the control unit being configured to carry out the predetermined, automatically carried-out event, and a display screen for display of information when the check has shown that the event has not occurred. ### Claim 2 (depends on 1) The medical device according to claim 1, wherein the control unit is configured to send a signal to display the information to the display screen, and the information is displayed on the display screen without any action by a user. ### Claim 3 (depends on 1) The medical device according to claim 1, wherein the event includes starting the medical device at the predetermined point in time and/or controlling an actuator or a sensor and/or running a predetermined process. ### Claim 4 (depends on 1) The medical device according to claim 1, further comprising a time recording device for recording the predetermined point in time, wherein the check includes a comparison of a point in time of start-up of the mechanical device with the predetermined time, and the display occurs when the time occurs at least a predetermined amount after the predetermined time. ### Claim 5 (depends on 1) The medical device according to claim 1, further comprising a memory for storing an event information when the event has occurred, wherein the check includes readout of the event information. ### Claim 6 (depends on 1) The medical device according to claim 1, further comprising a sensor for detecting a property of a liquid in the medical device, wherein the check includes a comparison of the property thus detected with a preselected value. ### Claim 7 (depends on 1) The medical device according to claim 1, wherein the device is a device for a blood treatment. ### Claim 8 (depends on 1) The medical device according to claim 1, wherein the information displayed includes an interactive input element which causes the control unit, on activation by the user, to start a process. ### Claim 9 (depends on 1) The medical device according to claim 1, wherein the control unit is configured for display of a selection of at least one option for adjustment of the medical device by a user on the display. ### Claim 10 (depends on 9) The medical device according to claim 9, wherein a first option of the at least one operation is a first cleaning process and a second option of the at least one operation is a second cleaning process, wherein duration of the first cleaning process is longer than duration of the second cleaning process. ### Claim 11 (depends on 1) The medical device according to claim 1, wherein the device has a user interface for turning the check on and off, and wherein the device is configured to carry out at least one process automatically when the check is turned off after a start-up of the device. ### Claim 12 (depends on 11) The medical device according to claim 11, wherein the automatically executed process is a process which is saved for automatic execution in a memory of the device as a process to be carried out automatically with an automatic start of the device. ### Claim 13 (depends on 1) The medical device according to claim 1, wherein the event includes starting the medical device at the predetermined point in time and/or controlling an actuator or a sensor and/or running a predetermined process selected from the group consisting of a cleaning process, a rinsing process, and a disinfection process. ### Claim 14 (depends on 1) The medical device according to claim 1, further comprising a conductivity sensor for detecting a property of a liquid in the medical device, wherein the check includes a comparison of the property thus detected with a preselected value. ### Claim 15 (depends on 1) The medical device according to claim 1, wherein the device is a device for a blood treatment selected from the group consisting of an extracorporeal blood treatment machine and a dialysis machine. ### Claim 16 (depends on 1) The medical device according to claim 1, wherein the information displayed includes an interactive input element which causes the control unit, on activation by the user, to start a cleaning process.
