Abstract
A method and device for controlling a biosensor system. The method includes a shaft alignment step of aligning an actuator shaft of a valve actuator, which rotates a valve provided in the biosensor cartridge, and an actuator shaft of a pump actuator, which rotates a pump, to initial positions, a loading step of moving down the valve actuator and the pump actuator when the biosensor cartridge is inserted, and a diagnosing step of sensing the bio-substance by rotating the valve and the pump. Accordingly, there is an advantage that it is possible to automatically diagnose a bio-substance through a simple process of inserting the biosensor cartridge into the diagnostic device.
Claims17
A biosensor system comprising:
- a biosensor cartridge comprising a frame disposed in a housing, a channel formed in the frame and configured to provide a path for flow of a buffer solution or a sample solution, a biosensor coupled to the frame and configured to detect a bio-substance, and a pump configured to generate a flow-driving force to the buffer solution or the sample solution flowing in the channel;
- and
- a diagnostic device comprising a diagnostic device housing having a cartridge insertion port into which the biosensor cartridge is inserted, and a pump actuator disposed in the diagnostic device housing, coupled to the pump, and configured to rotate the pump.
A biosensor system comprising:
- a biosensor cartridge comprising a frame disposed in a housing, a channel formed in the frame and configured to provide a path for flow of a buffer solution or a sample solution, a biosensor coupled to the frame and configured to detect a bio-substance, and a valve configured to allow the buffer solution or the sample solution to flow to the biosensor by selectively opening or closing the channel;
- and
- a diagnostic device comprising a diagnostic device housing having a cartridge insertion port into which the biosensor cartridge is inserted, and a valve actuator disposed in the diagnostic device housing, coupled to the valve, and configured to rotate the valve,
- wherein the channel comprises:
- a buffer solution channel into which the buffer solution flows;
- a sample solution channel into which the sample solution flows;
- and
- a sensing channel configured to guide the buffer solution or the sample solution to the biosensor, and
- the valve brings the buffer solution channel and the sensing channel into fluid communication with each other and then brings the sample solution channel and the sensing channel into fluid communication with each other.
A method of controlling a biosensor system comprising a diagnostic device to which a biosensor cartridge comprising a biosensor is coupled and that senses a bio-substance contained in a sample solution introduced in the biosensor cartridge, the method performed by a biosensor system and comprising:
- aligning an actuator shaft of a valve actuator, which rotates a valve provided in the biosensor cartridge, and an actuator shaft of a pump actuator, which rotates a pump, to initial positions;
- moving down the valve actuator and the pump actuator when the biosensor cartridge is inserted;
- and
- sensing the bio-substance by rotating the valve and the pump.
