Application Models

Based on our experience between our clients, ITEC shares with you the following possible application scenarios:

 Model 1: Oximetry Channel of Vital Signs Monitor / Pulse Oximetry OEM Board

In this implementation CHIPO2 outputs data in serial RS-232 format. Power and communication interface may be isolated. This configuration is the simplest, and represents commonly known “OEM SpO2 Board”.

 Model 2: Hand-Held Spot-Check or Continuous Monitoring Pulse Oximeter

In this implementation CHIPO2 controls numeric display (possible bar graph, not shown); reads keypad; controls speaker for pulse beep and also possible alarm tones.

Model 3: Pulse Oximeter with Graphics Display

In this implementation CHIPO2 controls graphics display to display Oximetry waveforms as well as numeric data; reads keypad; controls speaker for pulse beep and alarm tones.

Model 4: RF Pulse Oximeter

In this implementation CHIPO2 outputs data, and controls RF Transceiver. Internal software implements redundant “packet radio” interface, CRC data protection, etc.
Very low power consumption of CHIPO2 could be further reduced by placing it into “sleep” mode, controlled by either internal timer, or RF receiver event.
