CGH and SUTD develop lightweight monitoring device to detect real-time bleeding from wounds
Changi General Hospital (CGH) and the Singapore University of Technology and Design (SUTD) have developed the Blood WArning Technology with Continuous Haemoglobin (BWATCH) sensor, a lightweight monitoring device placed over a patient's bandage that detects real-time bleeding from wound sites following invasive medical procedures.
BWATCH was tested and validated in an observational clinical trial involving 250 patients at CGH with a dialysis catheter inserted or removed. The device was securely placed over their dressing for at least six hours. During the trial, 36 episodes of bleeding occurred and the sensor detected all instances of early bleeding. The blood loss detected in the bleeding episodes was minimal and the bandages were only partially stained.
