Abstract
A transcutaneous non-invasive device and method for measuring bilirubin levels is provided. The device and method utilize optical, electrical, and mechanical means in communication with processing means to calculate the serum bilirubin concentration. Blanching pressure is applied to the tissue, whose thickness is measured. The level of bilirubin is calculated from the thickness of the tissue and the detected and measured values of radiation transmitted through the living tissue.
Claims22
A non-invasive device for measuring the bilirubin level of a subject comprising:
- at least one radiation source for radiating a subject's living tissue, said at least one radiation source configured to emit radiation in at least first and second wavelengths;
- at least one detector for detecting rays transmitted through said tissue;
- means for applying blanching pressure to the portion of the subject's living tissue;
- means for measuring the thickness of the portion of the subject's living tissue through which radiation is being transmitted;
- and
- processing means in communication with said at least one radiation source, said at least one detector and said means for measuring thickness,
- wherein said processing means are configured to calculate the bilirubin level of said subject using data obtained from said at least one detector and from said thickness measurement means.
A method for measuring the bilirubin level of a subject comprising the steps of:
- applying blanching pressure to the subject's living tissue;
- determining the thickness of the subject's blanched tissue;
- transmitting at least two different wavelengths through a subject's blanched tissue;
- detecting and recording the signals transmitted through the tissue having blanching pressure applied thereto;
- and
- calculating the bilirubin level in the subject using data obtained from said recorded signals and said thickness.
