Abstract

A monitoring system is disclosed. The system comprises a range detection system, configured for scanning a scene to provide range data arranged gridwise over a plurality of picture elements, and a data processing system configured for processing the range data to monitor hygienic activity, preferably hand hygienic activity, of an individual in the scene. Preferably, the picture elements are devoid of any color data and any grayscale data. In some embodiments of the present invention the data processing system identifies one or more of the moments for hand hygiene as defined by the World Health Organization, and monitors the hygienic activity in relation to these five moments.

Claims

1. A monitoring system, comprising:

a range detection system configured for scanning a scene and to provide range data arranged gridwise over a plurality of picture elements; and

a data processing system configured for processing said range data to monitor hygienic activity of an individual in said scene.

2. The system of claim 1, wherein said picture elements are devoid of any color data and any grayscale data.

3. The system of claim 1, wherein said range detection system provides range imaging data, and said data processing system is configured for removing from each picture-element any color data or grayscale data.

4. The system according to claim 1, wherein said data processing system is configured to identify said hygienic activity during at least one time interval selected from the group consisting of (i) a time interval ending before said individual contacts a patient in said scene, (ii) a time interval ending before said individual performs an aseptic task, (iii) a time interval ending after said individual performs said aseptic task, (iv) a time interval beginning after said individual is exposed to a body fluid of said patient, (v) a time interval beginning after said individual contacts said patient, and (vi) a time interval beginning after said individual contacts objects nearby said patient.

6. The system according to claim 1, wherein said data processing system is configured to identify glove wearing or removal motion of said individual.

9. The system according to claim 1, wherein said data processing system is configured to identify access of said individual to a patient in said scene, and to determine a time window encompassing both said hygienic activity and said access.

11. The system according to claim 1, wherein said data processing system is configured to identify a medical treatment device in said scene, and contact events between said individual and said medical treatment device, and to determine a time window encompassing both said hygienic activity and said contact events.

12. The system according to claim 1, wherein said data processing system is configured to identify contact events between said individual and an organ of a patient in said scene, and to issue a notification when said contact events are not preceded by said hygienic activity.

13. The system according to claim 1, wherein said data processing system is configured to identify points of contact between said individual and objects in said scene, and to map said points of contact over said scene.

14. The system according to claim 11, wherein said data processing system is configured to track a cleansing device in said scene and to update said map responsively to said tracking.

15. The system according to claim 13, further comprising a control circuit configured to signal a robotic cleansing device to access and disinfect said points of contact.

16. The system according to claim 1, further comprising a communication system configured to communicate with a sensor mounted on said individual, and to receive from said sensor signals pertaining to hygienic activity or lack thereof, wherein said data processing system is configured for determining said hygienic activity based, at least in part, on said signals.

18. The system according to claim 1, wherein said data processing system is configured to identify contact events between said individual and a medical treatment device or a patient, and to analyze said contact events to determine productivity of said individual.

65. A method of monitoring a condition of a medical environment, comprising:

obtaining a map of the environment, said map comprising locations in the environment identified as being infected;

receiving tracking data pertaining to motion of a cleansing device in relation to said locations; and

updating said map based, at least in part, on said tracking data.

66. The method according to claim 65, further comprising generating said map by monitoring points of contact between individuals and objects in the environment.

68. The method according to claim 66, wherein said receiving said tracking data comprises receiving signals generated by said cleansing device.

69. The method according to claim 66, wherein said receiving said tracking data comprises receiving signals reflected by said cleansing device.

71. The method according to claim 65, wherein said cleansing device is a robotic cleansing device and the method further comprises controlling said robotic cleansing device to access and disinfect said points of contact.

67. (canceled)

73. The method according to claim 67, wherein said receiving said tracking data comprises receiving signals generated or reflected by said cleansing device.
