Deep vein thrombosis detection device

A device for detection of deep vein thrombosis (DVT), the device comprising:

• a sleeve configured to be placed on a lower-limb of a person;
• at least one photoplethysmography (PPG) sensor positioned in the sleeve, wherein the at least one sensor is positioned over a popliteal vein of the lower-limb, a femoral vein of the lower-limb, an iliac vein of the lower-limb, or their associated microvasculature;
• and
• a microcontroller positioned in the sleeve, the microcontroller in signal communication with the at least one photoplethysmography (PPG) sensor, wherein the microprocessor is capable of differentiating a blood flow signal indicating an absence of DVT signal and a blood flow signal indicating a potential venous occlusion or an obstruction associated with DVT.

A device for detection of deep vein thrombosis (DVT), the device comprising:

• a band having a detection device unit attached thereto, the band configured to be placed on a lower-limb of a person;
• at least one photoplethysmography (PPG) sensor attached to the band, wherein at least one sensor is positioned over a popliteal vein of the lower-limb, a femoral vein of the lower-limb, an iliac vein of the lower-limb, or their associated microvasculature;
• and
• a microcontroller positioned in the sleeve, the microcontroller in signal communication with the at least one photoplethysmography (PPG) sensor, wherein the microprocessor is capable of differentiating a blood flow signal indicating an absence of DVT signal and a blood flow signal indicating a potential venous occlusion or an obstruction associated with DVT.

A method of using a device for determination of deep vein thrombosis, the method comprising:

• applying the device comprising an optical sensor over a popliteal vein of a lower-limb of a person, a femoral vein of the lower-limb of a person, an iliac vein of the lower-limb of a person, or their associated microvasculature;
• initiating by the device an automated, timed measurement sequence;
• acquiring PPG data by the PPG sensor;
• processing the acquired PPG data by a microcontroller;
• and
• indicating whether the acquired physiological signal exhibits a characteristic consistent with a potential venous occlusion or absence thereof.
