Abstract
A device comprising a light transmission and detection system having transducers (10, 20, 7, 8), control means (5) and output means (7). The transducers are placed at various sites on the body of a patient and the light absorbed and/or reflected at these sites is measured and signals related to vasomotor activity are collected. The output can take the form of a detailed display of the vasomotor signals collected from the transducers (10, 20, 7, 8) to a simple indication of a condition present or absent. For example, the presence of a unilateral DVT can be detected by measuring the dissimilarity between two transducer signals from the soles of a patient's feet. The invention can also be used to provide an indication or not of for example, DVT and diabetic peripheral neuropathy.
Claims14
A device comprising a light transmission and detection system to assess vasomotor activity at individual sites on a body for the monitoring and assessment of a range of clinical conditions including suspected DVT and diabetic peripheral neuropathy.
A vasomotor activity assessment device including:
- a. two or more transducers, each transducer being configured for attachment to a respective portion of a body, wherein each transducer includes:
- (1) alight emitter situated to emit light into the portion of the body upon which the light emitter's transducer is situated, and
- (2) a light detector situated to receive light from the light emitter through the portion of the body;
- b. a control unit wherein:
- (1) signals from the light detectors of the transducers are received, the signals being indicative of the light received by the light detectors;
- and
- (2) the signals from the light detectors are compared to indicate differences in blood circulation between the respective portions of the body upon which the transducers are situated.
A vasomotor activity assessment method including the steps of:
- a. providing two or more transducers, each transducer being attached to a respective portion of a body, wherein each transducer includes:
- (1) alight emitter situated to emit light into the portion of the body upon which the light emitter's transducer is situated, and
- (2) a light detector situated to receive light from the light emitter through the portion of the body;
- b. receiving signals from the light detectors of the transducers, the signals being indicative of the light received by the light detectors;
- and
- c. comparing the signals from the light detectors to indicate differences in blood circulation between the respective portions of the body upon which the transducers are situated.
