The formation of a blood clot in a deep vein, often in the legs or Deep Vein Thrombosis (DVT), can result in life-threatening issues. A workforce from Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) in Trivandrum have come up with a device that can facilitate the move of blood from the veins in the legs thus stopping DVT.

The device can provide relief to patients affected by prolonged immobility, bedridden condition, postoperative immobilization, paralysis of the legs, many of whom are affected by DVT causing pain, swelling, redness, warmth and engorgement of the veins of area. Detachment of the clot and its transport to the arteries carrying the unclean blood to the lungs can cause “pulmonary arterial embolism”, a potentially fatal complication.

The engineering team will include Jithin Krishnan, Biju Benjamin and Koruthu P Varughese from SCTIMST.

Such devices are so far imported which costed between 2 lakh to 5 lakh rupees. The device developed by the SCTIMST team can be put on the market for less than 1 lakh rupees.

The newly developed device works by compressing the leg veins in sequence to facilitate the flow of blood from the leg veins.

The compression pressure is adjusted so that the veins are compressed but not the arteries. It is equipped with closed loop monitoring of the compression pressure and also has controls via valves driven by an electronic circuit. Dedicated software and a control circuit are provided in the device to ensure that safe compression levels are always maintained.

The device is also equipped with an emergency power supply in the event of a power failure.

The license for the manufacture and sale of the device was transferred to Enproducts located in Kochi. This seven-year-old company has products in the market for automation and control.
