Abstract

A user interface (21) for an extracorporeal blood treatment machine is provided, as well as a system (200) for feedback control of a user. The system (200) comprises a controller (22), a sensor (108) and a device (107) for administration of a substance. The controller (22) is enabled to receive input from the user interface and send instructions to the user interface and the controller is arranged to control the operation of the device (107) for administration of a substance. The device (107) for administration of a substance is monitored by the sensor (108) and the controller (22) is enabled to receive input from the sensor (108) such that the controller is enabled to provide feedback to the user interface by said instructions. A method (40) for performing a critical action in a system (200) is also provided.

Claims

1. A user interface for an extracorporeal blood treatment machine, which user interface comprises at least one screen, at least one memory comprising at least two images, at least a controller and at least one key, the controller is programmed to:

detect activation of the at least one key;

display on the screen a first image which in the memory is assigned to the activated key,

and whereupon the controller is further programmed to;

block the user interface until a first signal is received; and

upon receipt of the first signal, unblock the user interface, and display on the screen a second image.

2. The user interface according to claim 1, wherein the controller is further programmed to, before blocking the user interface:

highlight precisely one operational key; and

detect activation of the precisely one operational key.

3. The user interface according to claim 1, wherein the memory comprises at least three images, and wherein the controller is further programmed to:

highlight precisely one operational key;

detect activation of the precisely one operational key;

block the user interface until a second signal is received; and

upon receipt of the second signal, display on the screen a third image.

4. The user interface according to claim 1, wherein the screen is a touch screen, and further wherein the key is a touch key.

5. The user interface according to claim 1, wherein the first signal is a sensor signal.

6. The user interface according to claim 3, wherein the first, second or third image forms part of a video sequence.

7. The user interface according to claim 1, further comprising a cancellation key,

and whereupon the controller is further programmed to:

detect activation of the cancellation key; and

unblock the user interface.

8. The user interface according to claim 1, further comprising a supplementary key,

and whereupon the controller is further programmed to:

detect activation of the supplementary key; and

display on the screen an supplementary image which in the memory is assigned to the supplementary key.

9. A system for feedback control of a user interface according to claim 1 comprising a controller, a sensor and a device for performing an operation on a machine for extracorporeal blood treatment, wherein

the controller is configured to receive input from the user interface and send instructions to the user interface;

the controller is configured to control the operation of the device;

the device is monitored by the sensor; and

the controller is configured to receive input from the sensor such that the controller is configured to provide feedback to the user interface by said instructions.

10. The system according to claim 9, wherein the device is a device for administration of a substance, the operation is administration of a substance, and the controller is arranged to control the operation of the device for administration of the substance.

11. The system according to claim 9, wherein the sensor comprises at least one of a load sensor, an optical sensor, a magnetic sensor and an ultrasonic sensor.

13. A machine for extracorporeal blood treatment comprising a user interface, wherein the user interface comprises at least one screen, at least one memory comprising at least two images, at least a controller, and at least one key, wherein the controller is configured to:

detect activation of the at least one key;

display on the screen a first image which in the memory is assigned to the activated key, and

wherein the controller is further configured to;

block the user interface until a first signal is received; and

upon receipt of the first signal, unblock the user interface, and display on the screen a second image.

12. A machine according to claim 13, wherein the machine further comprises:

at least one blood pump;

at least one housing zone for receiving at least one extracorporeal blood circuit in a position wherein the at least one extracorporeal blood circuit is operatively associated with the blood pump;

at least a machine controller; and

the at least one user interface for dialogue between an operator and the machine controller.

14. The machine according to claim 13, wherein the machine is a dialysis machine.

15. A method for performing a critical action in a system for extracorporeal blood treatment, wherein the system comprises a user interface including a screen, and further wherein the system comprises a sensor associated with the critical action, said method comprising:

blocking the user interface;

detecting a first signal from the sensor associated with the critical action; and

unblocking the user interface when the first signal is detected.

16. The method according to claim 15, wherein the method further comprises, before blocking the user interface:

highlighting precisely one operational key; and

detecting activation of the precisely one operational key;

blocking the user interface until a second signal is received; and

upon receipt of the second signal, displaying on the screen a third image.

17. The method according to claim 15, wherein the method further comprises, before detecting a first signal from the sensor associated with the critical action:

activating the device for administration of a substance.

18. A computer-readable medium having embodied thereon a computer program for processing by a computer, wherein the computer program comprises code segments for performing the method according to claim 15.
