Abstract

A medical device, such as a peritoneal dialysis machine, includes a sensor for sensing motion and/or user proximity in the vicinity of the medical device for the purpose of automated dimming a display of the medical device. In the event of a lack of user-activity on a machine interface and a lack of movement detected by the proximity sensor, the machine display is automatically dimmed to minimize power-consumption and provide an enhanced medical device for night therapies in a home or clinic environment. The machine display may be dimmed in the event of an alarm-free machine condition, where no machine activity is detected and/or where no movement is detected by the sensor over one or more time periods. When machine activity is detected, when movement is detected by the proximity sensor, and/or in the event of a machine alarm or warning, the machine display may be automatically undimmed.

Claims

1. A medical system, comprising:

a medical device comprising;

a display, and

a machine interface that receives non-contact gesture-based input from a user used to control operations and functions of the medical device; and

a display dimness control device for controlling a dimness of the display, wherein the display dimness control device includes;

at least one sensor that includes at least one motion sensor, wherein the at least one sensor detects at least one non-contact motion of the user in a vicinity of the display dimness control device; and

a control unit coupled to the medical device and the at least one sensor, the control unit configured to control the dimness of the display based on a state of the medical device determined from an input received from the machine interface and based on an input received from the at least one sensor, the control unit configured to control distinct portions of the display, during a dimmed state of the display, such that at least a portion of the display remains undimmed during the dimmed state of the display,

wherein processing of the non-contact gesture-based input received at the machine interface corresponds to;

(i) detection of the at least one non-contact-motion by the at least one sensor that is used by the control unit to automatically control dimness of the display, and

(ii) detection of user activity input used to control operations and functions of the medical device, and

wherein the control unit causes the display to automatically enter the dimmed state when;

the medical device is in an alarm-free condition for a first time period,

no activity occurs on the machine interface of the medical device for a second time period, and

no movement is detected in a vicinity of the medical device by the at least one sensor for a third time period.

2. The medical system according to claim 1, wherein the state of the medical device includes an alarm-free condition of the medical device.

3. The medical system according to claim 1, wherein the state of the medical device includes a condition of gesture-based interaction with the machine interface of the medical device.

4. The medical system according to claim 1, wherein the medical device is a peritoneal dialysis machine.

5. The medical system according to claim 1, wherein the medical device is a hemodialysis machine.

6. The medical system according to claim 1, wherein the control unit also controls operations of the medical device.

7. The medical system according to claim 1, wherein the first time period, the second time period, and the third time period are independent of each other.

8. The medical system according to claim 1, wherein the control unit causes the display to automatically exit the dimmed state according to at least one of the following:

(i) when an alarm occurs on the medical device, (ii) when user activity occurs on the machine interface, and/or (iii) when movement is detected by the at least one sensor in the vicinity of the medical device.

9. The medical system according to claim 1, wherein, during the dimmed state of the display, the portion of the display that remains undimmed comprises a clock on the display.

10. The medical system according to claim 9, wherein the clock is a therapy clock showing a duration of a therapy performed by the medical device.

11. The medical system according to claim 1, wherein, during the dimmed state of the display, the control unit controls presentation of treatment status information on the display.

12. A method for automated dimness control of a medical device, comprising:

monitoring for movement in proximity of the medical device using at least one sensor, wherein the at least one sensor detects at least non-contact motion of a user in a vicinity of the medical device;

monitoring for an alarm on the medical device;

monitoring for activity on a machine interface of the medical device, wherein the machine interface receives non-contact gesture-based input from a user used to control operations and functions of the medical device; and

automatically causing a display of the medical device to enter a dimmed state when;

the medical device is in an alarm-free condition for a first time period,

no activity on the machine interface occurs for a second time period, and

no movement is detected in a vicinity of the medical device by the at least one sensor for a third time period, wherein in the dimmed state, at least a portion of the display remains undimmed.

13. The method according to claim 12, further comprising:

causing the display to automatically exit the dimmed state according to at least one of the following;

(i) when an alarm occurs on the medical device, (ii) when user activity occurs on the machine interface, and/or (iii) when movement is detected by the at least one sensor in the vicinity of the medical device.

14. The method according to claim 12, wherein the medical device is a peritoneal dialysis machine.

15. The method according to claim 12, wherein the dialysis machine is a hemodialysis machine.

16. The method according to claim 12, wherein the first time period, the second time period, and the third time period are independent of each other.

19. The method according to claim 12, wherein, during the dimmed state of the display, treatment status information is presented on the display.

17. The method according 12, wherein, during the dimmed state of the display, a clock is presented on the display.

18. The medical system according to claim 17, wherein the clock is a therapy clock showing a duration of a therapy performed by the medical device.

20. A non-transitory computer-readable medium storing software for automated dimness control of a medical device, the software comprising:

executable code that controls monitoring for movement in proximity of the medical device using at least one sensor, wherein the at least one sensor detects non-contact motion of a user in a vicinity of the medical device;

executable code that controls monitoring for an alarm on the medical device;

executable code that controls monitoring for activity on a machine interface of the medical device, wherein the machine interface receives non-contact gesture-based input from a user used to control operations and functions of the medical device;

executable code that automatically causes a display of the medical device to enter a dimmed state when;

the medical device is in an alarm-free condition for a first time period,

no activity on the machine interface occurs for a second time period, and

no movement is detected in a vicinity of the medical device by the at least one sensor for a third time period; and
