PulSox: A healthcare (foot)wearable

PulSox revolutionizes pediatric pulse oximetry with a wireless wearable device and patient monitoring app. Designed for long-term patient care, PulSox untethers children from vital sign monitoring stands, enabling them to move and play freely.

A HOLISTIC, INTEGRATED PULSE OXIMETRY SYSTEM

PulSox is a combination of a sock, outsole, wireless pulse oximeter, and mobile app. The sock and outsole have two designated attachment points for securing the pulse oximeter, which uses a colorimeter to accurately adjust data to eliminating racial bias. Blood oxygen levels are wirelessly sent to a mobile app for use by medical professionals, displaying alerts and specific data for each patient.

PulSox is easily accessible to healthcare providers via a wall-mounted product dispenser.
