KAVACH (Quant PPH – A Low Cost PPH Monitoring Diaper)

KAVACH is a diaper with a built-in strip that turns green, yellow, or red to flag dangerous post-birth bleeding early, since doctors often underestimate blood loss by eye.

Outcome Metrics

• Estimated Dev Cost: Base version ~₹165–₹186 per unit (reagent + diaper + nitrocellulose strips + indicator strips); future electronic version adds ~₹1,900–₹3,100 in sensor/connectivity hardware
• Increase in early detection of postpartum haemorrhage (PPH)
• Improvement in accuracy of postpartum blood loss assessment
• Reduction in underestimation of blood loss by visual assessment
• Reduction in time required to identify dangerous bleeding
• Improvement in timely clinical intervention and escalation of care
• Reduction in severe maternal complications related to delayed PPH detection
• Detection accuracy, response time, usability, and clinician satisfaction rates
