Deep Vein Thrombosis (DVT)

14th September, 2020 Science and Technology

Context: Indigenous device developed by SCTIMST of Dept. of S&T can help prevent blood clot in deep vein and lowers cost of saving life threatening conditions

  • The formation of a blood clot in a deep vein, usually in the legs or Deep Vein Thrombosis (DVT), can lead to life threatening complications.
  • Scientists have come up with a device that can facilitate flow of blood from the veins in the legs thus preventing DVT.

About the device:

  • Purpose: The device can bring relief to patients affected by prolonged immobility, bed ridden state, post-operative immobilization, paralysis of legs, a large number of whom are affected by DVT causing pain, swelling, redness, warmth and engorged surface veins.
  • The detachment of the clot and its transport to the arteries carrying impure blood to the lungs can cause ‘pulmonary artery embolism’, a potentially life-threatening complication.
  • Developed by: A team from Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum (SCTIMST), an autonomous institute of the Department of Science and Technology, Government of India has developed a device for the prevention of DVT.
  • Present scenario: Such devices which are so far imported cost between 2 lakh to 5 lakh rupees whereas the device developed by SCTIMST team can be placed in the market for less than 1 lakh rupees.
  • Working: The newly developed device works by compressing the veins in the legs in sequence so that the flow of blood from the veins in the legs is facilitated.
  • The compression pressure is set in such a way that the veins are compressed but not the arteries.
  • It is equipped with closed loop monitoring of compression pressure and also has controls through valves which are driven by an electronic circuit.
  • A 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 a power supply back-up in case of power failure.
