Abstract
A biosensor diagnostic device can include an interface configured to receive an electrical signal from a biosensor cartridge in response to being connected to a connection terminal of the biosensor cartridge; an image reader configured to capture a code image on the biosensor cartridge. And a signal processor configured to process a signal received from the interface for generating diagnostic result information. Also, the biosensor diagnostic device can include a wireless transceiver configured to transmit information corresponding to the code image and the diagnostic result information to a server or an external terminal.
Claims17
A biosensor diagnostic device comprising:
- an interface configured to receive an electrical signal from a biosensor cartridge in response to being connected to a connection terminal of the biosensor cartridge;
- an image reader configured to capture a code image on the biosensor cartridge;
- a signal processor configured to process a signal received from the interface for generating diagnostic result information;
- and
- a wireless transceiver configured to transmit information corresponding to the code image and the diagnostic result information to a server or an external terminal,
- wherein the signal processor is configured to:
- extract code information based on the code image captured by the image reader,
- transmit the code information to the server for authentication, and
- in response to receiving authentication information from the server, supply a first electrical signal of a first level to the biosensor cartridge through the interface during a first period and receive a second electrical signal of a second level from the biosensor cartridge during a second period after the first period.
