5. Uterine tamponade
According to the Massachusetts General Hospital, around 130, 000 women die every year due to postpartum hemorrhage, or PPH in short. (PPH is the loss of blood within the first 24 hours following childbirth.) A huge majority of this cases occur in the developing countries due to poor healthcare resources.
The balloon tamponades used in the US are one-time use and costs about US$400 per piece. Fortunately, the ultra-low-cost uterine balloon tamponade developed by the Massachusetts General Hospital costs less than US$5 a piece and uses components that are available even in regions with the poorest or non-existent healthcare systems to stop bleeding effectively.
