ABSTRACT:
A non-invasive probe for application to a body part, such as a finger, toe or limb, for the detection of a medical condition of the subject includes a housing defining a compartment closed at one end and open at the opposite end for receiving the distal end of the subject's body part including its terminal-most extremity, a sensor for sensing a predetermined condition of the body part after being received within the compartment, and a removable liner lining the inner surface of the housing, to facilitate the insertion of the body part into the compartment. The described probe is one which senses changes in the peripheral arterial tone as manifested by changes in the pulsatile arterial blood volume and/or changes in the oxygen saturation level in a terminal extremity of a body part, and includes a number of other features particularly useful in such probes.
