CMS
 
The TM80 Telemetry Monitors are worn on patients. As shown in the figure above, 
patients’ physiological information collected by the TM80 Telemetry Monitors is 
transmitted through the low power consumption Wi-Fi modules built in the 
telemetry monitors. Wireless signals are acquired by AP arrays and then are 
transmitted to the CMS through the existing network system of the hospital. On the 
CMS, the information is displayed, stored and processed based on a certain 
algorithm and alarms are generated. In addition, patients can seek for help from 
nurses on the CMS side by using the nurse call function. When a TM80 Telemetry 
Monitor is connected to the CMS, doctors can view its patient information in the 
ViewBed window of the CMS.
