TOOL FOR SCREENING FOR A DEFECT, SUCH AS PERIPHERAL ARTERIAL DISEASE

摘要

The invention relates to the field of screening for peripheral arterial disease. Specifically, the invention relates to a screening tool (2, 102) comprising: a compression body (20, 120) capable of engaging with a portion (10a) of a limb (10) of the patient to be compressed; a compression means (30, 130) capable of compressing said contact surface (24, 124) against said portion (10a) of the limb (10) of the patient to be compressed; a measurement means (40, 140) capable of structurally and functionally engaging with a portion (10b) of the limb (10) of the patient to be examined, as well as generating, by means of the optical detection of one or more component(s) of the blood, a measurement signal that is characteristic of an arterial pulse in the portion (10b) of the limb (10) of the patient to be examined during a measurement phase. The invention is essentially characterized in that the compression means (30, 130) is capable of generating, on said portion (10a) to be compressed, a measurement pressure substantially equal to a threshold pressure value during the entire measurement phase, and in that the screening tool (2, 102) also comprises: a calculation means (60, 160) capable of transmitting, from the measurement signal, a negative diagnostic signal when the arterial pulse in the portion to be examined is greater than a threshold diagnostic value, and of transmitting a positive diagnostic signal when said arterial pulse is lower than said threshold diagnostic value; and an expression means (70, 170) capable of expressing negative diagnostic information upon receipt of the negative diagnostic signal from the calculation means (60, 160).
