The ViSi Mobile vital signs monitor built by Sotera Wireless of San Diego, California. This wearable sensor pack uses Wi-Fi technology and is claimed to allow doctors using a tablet or smartphone to remotely monitor patient vital signs with the accuracy of an intensive care unit.
Designed around the concept of “monitoring in motion,” the ViSi Mobile consists of several units made of rugged, water-resistant plastic. These include a wrist unit with monitor readout, chest sensors, a blood pressure cuff monitor and a thumb sensor. These are connected to the existing hospital data infrastructure via Wi-Fi with WPA2 encryption for security.
