Abstract

A system for detection of bilirubin content in neonate'"'"'s skin includes at least one camera configured to capture at least one image of neonate'"'"'s skin and a reference image, a display system, a communication interface and a control unit configured to control functioning of other elements of the system. The control unit is further configured to detect bilirubin level by comparing image of neonate'"'"'s skin and reference image. Furthermore, the control unit is configured to transfer said image of neonate'"'"'s skin to at least one of communication interface and display system. The reference image is a single image acquired from any one of the dermal zones or multiple images from more than one dermal zones of neonate under observation.

Claims

1. A system for detection of bilirubin content in neonate'"'"'s skin, said system comprising:

at least one camera configured to capture at least one image of neonate'"'"'s skin and a reference image;

a display system;

a communication interface; and

a control unit configured to control functioning of at least one of said camera, said display system and said communication interface,

wherein

said reference image is a single image acquired from any one of the dermal zones or multiple images from more than one dermal zones of neonate under observation;

said control unit is configured to detect bilirubin level by comparing said image of neonate'"'"'s skin and said reference image; and

said control unit is configured to transfer said image of neonate'"'"'s skin to at least one of communication interface and display system.

2. The system as claimed in claim 1, wherein said camera includes a light source that is configured to provide necessary light to capture at least one of image of neonate'"'"'s skin and reference image.

3. The system as claimed in claim 1 further includes at least one camera bellow configured to prevent entry of ambient light into a camera'"'"'s field of image acquisition.

4. The system as claimed in claim 1, wherein said system further comprising:

an optical sensor having optical reader capabilities to identify neonate under observation; and

at least one of neonate'"'"'s Icterus diagnostic report and medical records,

wherein

said control unit is configured to record said detected bilirubin level into corresponding said neonate'"'"'s Icterus diagnostic report and said medical records via communication interface.

5. The system as claimed in claim 1 further includes an ambient light sensor configured to sense the presence of ambient light within said camera'"'"'s field of image acquisition, wherein said control unit is configured to alert user of system regarding said ambient light present within camera'"'"'s field of image acquisition.

6. A method for non-invasive measurement of bilirubin level, wherein said method comprising:

obtaining at least one reference image and image of neonate'"'"'s skin in a controlled environment;

storing said reference image; and

extracting the features of obtained reference image and image of neonate'"'"'s skin,

wherein

bilirubin level is measured by comparing said extracted features of image of neonate'"'"'s skin and reference image; and

said reference image is a single image acquired from any one of the dermal zones or multiple images from more than one dermal zones of neonate under observation.

7. The method as claimed in claim 6 further includes comparing the reference image with a gosset icterometer value before storing said reference image.

8. The method as claimed in claim 6, wherein said method further comprises of:

Identifying the said neonate using optical reader capabilities; and

recording said measured bilirubin level into corresponding at least one of neonate'"'"'s icteric diagnostic report and medical records.

9. The method as claimed in claim 6, wherein said controlled environment is provided by preventing entry of ambient light while obtaining at least one of reference image and image of neonate'"'"'s skin.

10. The method as claimed in claim 6 further includes transferring said obtained image of neonate'"'"'s skin via at least one communication interface;

and displaying said obtained image of neonate'"'"'s skin on an electronic display device, for in care-premises or remote physicians for diagnosis.
