CLAIMS:

1. Device (1) for determination of a bed fall risk of an individual (2), the device

(1) comprising:

a first port (3) for obtaining sensor data (100) related to movement and/or a vital sign of an individual (2),

an evaluation unit (4) for determining quality information indicating the quality of the sensor data (100),

a second port (5) for obtaining personal data (120) of the individual (2), a calculation unit (6) for calculation of a total risk score (114) of the individual

(2) based on the sensor data (100), the quality information (110) and the personal data (120), said total risk score indicating a bed fall risk of the individual (2), and

a third port (7) for output of the calculated total risk score.

2. Device (1) according to claim 1, wherein said sensor data comprises vital signs data and said device further comprises a vital signs data processing unit (9) for obtaining and processing the vital signs data (140) to generate a vital signs related risk score (111) and to assign a reliability value to said vital sign data (140) and/or said vital signs related risk score.

3. Device (1) according to claim 1, wherein said sensor data comprises video data and said device further comprises a video processing unit (8) for obtaining and processing the video data (130) to generate a video data related risk score (110) and to assign a reliability value to said video data (130) and/or said video data related risk score, in particular for determining movement and/or posture information indicating movement and/or posture of the individual.

4. Device (1) according to claim 2 and/or 3, wherein the evaluation unit (4) is configured to determine a variable risk score (112) of the individual (2) based on the vital signs related risk score (111) and its assigned reliability value and/or the video data related risk score (110) and its assigned reliability value.

5. Device (1) according to claim 4, wherein the evaluation unit (4) is configured to determine the variable risk score at discrete intervals or continually.

6. Device (1) according to claim 1, further comprising a classification unit (10) for obtaining the personal data (120) of the individual (2) and calculating an intrinsic risk score (113) therefrom, wherein the personal data (120) comprises one or more of age, gender, neurologic condition, health condition, health score, medical history, symptoms, disabilities, medication, falling history, psychologic profile.

7. Device (1) according to claim 4 and 6, wherein the calculation unit (6) is configured to calculate the total risk score (114) of the individual (2) from the intrinsic risk score (113) and the variable risk score (112).

8. Device (1) according to claim 3 and 6, wherein the classification unit (10) is further configured to obtain the video data related risk score (110) and its assigned reliability value and to determine or adjust the intrinsic risk score (113) based on the obtained video data related risk score (110) and its assigned reliability value.

9. Device (1) according to claim 1, further comprising an intervention unit (15) for determining an intervention based on the calculated total risk score, in particular based on the calculated total risk score (114) and personal data (120) of the individual (2).

10. Device (1) according to claim 1, wherein the first port (3) and the evaluation unit (4) are configured as a first entity, in particular for arrangement in the vicinity of the individual, and the second port (5), the calculation unit (6) and the third port (7) are configured as a second entity, in particular for arrangement remote from the individual (2).

11. System (11) for determination of a bed fall risk of an individual (2), the system comprising:

- at least one sensor (12, 13) for acquiring sensor data (100) related to movement and/or a vital sign of an individual (2), and

a device (1) according to claim 1 for determination of a bed fall risk of an individual (2) based on the acquired sensor data (100).

12. System (1 1) according to claim 11, wherein the at least one sensor (12; 13) comprises one or more of a camera, an accelerometer and a vital signs monitoring device , in particular a photoplethysmography sensor, a heart rate monitor, a blood pressure monitor, an Sp02 sensor and/or a respiration monitor.

13. System (1 1) according to claim 9, further comprising a feedback unit (14) for issuing feedback (150) to the individual (2), and access to at least one database (16) containing personal data (120) of the individual (2) and a staff schedule (17).

14. Method for determination of a bed fall risk of an individual, the method comprising the steps of:

obtaining sensor data related to movement and/or a vital sign of an individual, evaluating quality information indicating the quality of the sensor data, obtaining personal data of the individual,

- calculating a total risk score of the individual based on the sensor data, the quality information and the personal data, said total risk score indicating a bed fall risk of the individual (2), and

outputting the calculated total risk score.

15. Computer program comprising program code means for causing a computer to carry out the steps of the method as claimed in claim 14 when said computer program is carried out on a computer.
