Abstract

A line-switchable Near Field Communication (NFC) medical device comprising: a physiological measurement unit; a Micro Control Unit; a first NFC module in which there are a first memory and a first radio wave antenna communicating with an external second NFC module; a switching module communicating with the Micro Control Unit as well as the first NFC module and enabling or disabling information to be written into or read from the first NFC module'"'"'s first memory.

Claims

1. 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.

2. The line-switchable NFC medical device according to claim 1, wherein said external electronic device is provided with a second NFC module in which there is a second memory and a second radio wave antenna.

3. The line-switchable NFC medical device according to claim 2, wherein said switching module further comprises a first control switch communicating with said MCU and said first memory and enabling or disabling said MCU to write information into said first memory or read information from said first memory.

4. The line-switchable NFC medical device according to claim 3, wherein said switching module further comprises a second control switch communicating with said first radio wave antenna and said first memory, and enabling or disabling said information exchange between said first radio wave antenna and said first memory.

5. The line-switchable NFC medical device according to claim 4, wherein said second control switch controls information exchange between said first memory and said second NFC module of said external electronic device.

6. The line-switchable NFC medical device according to claim 2, wherein said switching module disconnects communication between said physiological measurement unit and said medical device'"'"'s first memory when said second NFC module approaching and communicating with said first NFC module, and said second NFC module executes information exchange with said first memory via said second radio wave antenna, and said switching module recovers said communication between said physiological measurement unit and said medical device'"'"'s first memory when information exchange completed.

7. The line-switchable NFC medical device according to claim 2, wherein said external electronic device is a smart mobile phone, a tablet computer, a notebook computer or a smart card.

8. The line-switchable NFC medical device according to claim 7, wherein said smart card is an Easy Card, an Octopus Card, an E-Wallet or a credit card.
