Patent ID: 8886120

Claim:
A line-switchable Near Field Communication (NFC) medical device for linking an external electronic device, comprising: a physiological measurement unit catching a person's at least one physiological parameter; a Micro Control Unit (MCU) communicating with said physiological measurement unit and running to activate measurement operations of said physiological measurement unit; a first NFC module comprising a first memory and a first radio wave antenna wherein said first radio wave antenna is used to communicate with said external electronic device; a switching module communicating with said MCU and said first NFC module and enabling or disabling information to be written into or read from said first NFC module's first memory; said switching module disconnects communication between said medical device's first radio wave antenna and said external electronic device during information exchange from said physiological measurement unit to said first memory, and recovers said communication between said medical device's first radio wave antenna and said external electronic device when information exchange completed.
