Project Title
ClotBot: A Clot Detecting Vascular Sheath
Design Challenge
Long-term vascular access sheaths are often associated with an increased risk of developing blood clots. Team ClotBot is creating a unique sheath capable of detecting the formation of blood clots inside its lumen. The sheath will work using complex bioimpedance and will notify the user of an impending blood clot before it becomes a threat to the patient's health, allowing the user to take preventative action.
Design Summary
The ClotBot uses bioimpedance to detect the beginning of clot formation within the lumen of long-term vascular access sheaths. Recent research has shown that as a clot begins to form in whole blood, the bioimpedance of the blood in that area increases with respect to time. The ClotBot will detect this increase and notify the user with an alarm should the bioimpedance reach a threshold value. For the prototype, we threaded the sheath with wires at the tip and the hub. The bioimpedance between these two wire electrodes will be detected and processed in Arduino. When the bioimpedance increase reaches a threshold value, an alarm will be triggered. The ClotBot shows a very high accuracy and precision in our testing.
