Multiparameter front end reference design for vital signs patient monitor

Overview

TopologyBuck Converter
Input voltage5.2 V
Output 13.3 V
IC revisionE1

Description

This reference design is for a multiparameter front end of a patient monitor that measures vital sign parameters like ECG, heart rate, SpO2 and respiration.it uses biosensing front end integrated circuits like the AFE4403 and ADS1292R devices, to measure these parameters. It also uses three TMP117 sensors to accurately measure skin temperature. This design can interface with the pace detection module to detect the pace pulse. The design also uses an isolated UART connection to transfer data to a computer. The entire front end subsytem runs on a rechargeable 3.7V li ion battery.
