Abstract: A clip sensor device for optical measuring vital signs of a subject is provided. The clip sensor device includes a internal supporting frame formed from an elongated plate configured to be folded into a desired orientation. A measuring probe is mounted on an upper surface of the frame. The measuring probe comprises a transmitter and receiver and configured for generating a time response of the blood perfused body tissue to the applied optical signal that is indicative of the vital signs of the subject. The clip sensor device also includes a pressing member mounted on the upper surface of the internal supporting frame. The pressing member includes one or more spring elements configured to provide a predetermined pressure on the blood perfused body tissue due to the deformation of the spring elements when said portion of blood perfused body tissue is applied against the pressing member.

Abstract: A method and system for optical measuring one or more vital signs of a human is described. The method includes generating an optical Pulse Width Modulated (PWM) signal modulated in accordance with a predetermined Pulse Width Modulation scheme. The PWM scheme includes one or more Pulse Width Modulations having different modulation frequencies. The method also includes applying the PWM optical signal to a measurement location in a blood perfused body tissue of the human and receiving light originated back from the measurement location. A photo current signal of a time response of the blood perfused body tissue to the PWM optical signal is indicative of the vital signs. The method includes generating a voltage signal from the photo current signal and processing the voltage signal for determining the vital signs.
