Postpartum Hemorrhage (PPH), the leading cause of maternal mortality worldwide, affects 14 million women and claims 150,000 lives annually. 99% of deaths occur in low-resource settings, where the majority of women give birth at home. The primary cause of PPH is uterine atony (80% of cases) and treatment includes administering uterotonic drugs to induce contraction and applying pressure on the uterine surface to minimize blood loss. In low-resource settings where uterotonic drugs failed to contract uterus in PPH management, then saline-filled condom tamponades have been used to apply pressure in situ for 24-48 hours until the uterus has fully contracted. However, this method is prone to leakage, causing loss of pressure and creating a need for constant monitoring. Tampostat is a self-regulating, low cost, emergency obstetric device designed specifically for use in low-resource settings by greatly increasing safety, efficacy, and ease-of-use over existing condom tamponades. While other condom tamponades take a volume-based approach, which may not account for varying uterus sizes, Tampostat is pressure-based and uses air to eliminate the need for saline. It features a safety valve to prevent over-inflation through auditory feedback and allows for periodic uterine contractions by constantly regulating the pressure. A proprietary probe, which allows a condom to be attached with an airtight seal, aids in guiding the condom into the uterus through guidance. With minimal training, a birth attendant in the field will be able to successfully administer Tampostat for about $1.50 USD.
