Process




thrum



thrum is an AI-supported monitoring system composed of a rechargeable ultrasound patch, a charging case, and a companion app. 

Sticker Mounting Station



Adaptive, Continuous BP Tracking



Blood pressure fluctuates from moment to moment. Medical providers can adjust tracking frequency based on a mother’s health condition, increasing it when risks are higher. 








More Accurate Readings



The ultrasound patch measures the levels of glucose, lactate, alcohol, caffeine in addition to blood pressure. thrum’s AI automatically adjusts the readings using the data collected. 

Symptom Log and AI Assistant



The app lets mothers log symptoms to share with their OBGYN, while also contributing anonymized symptom profiles to a shared catalog for broader pattern recognition.
