Bwatch
Wireless in-situ real-time bleeding detection
BWATCH™ is a lightweight device placed over a patient’s bandage for continuous monitoring of bleeding following invasive medical procedures. The device detects the unique optical property of blood haemoglobin and triggers an alarm with as little as 1mL blood loss from the wound. BWATCH™ has been validated in clinical trial involving 250 patients and is patented in Singapore and USA.
Features:
- Continuous monitoring for bleeding
- Detects blood specifically
- Does not require direct contact with wound or blood
- Rechargeable; reusable
- Wireless; lightweight
- Patented in Singapore and USA
Clinical Trial:
- Observational clinical trial involving 250 patients at CGH
- Patients had a dialysis catheter which was either just inserted or removed
- BWATCH™ was securely placed over their dressing for at least six hours
- 36 episodes of bleeding
- Device detected all instances of early bleeding
- Minimal blood loss
- Medical staff alerted when the alarm was triggered and took the necessary actions to prevent an escalation of bleeding
- Results published in peer-reviewed scientific journal Scientific Reports, A device for surveillance of vascular access sites for bleeding: results from a clinical evaluation trial by Chionh, C.Y., Soh, D.Y., Tan, C.H. et al.
