  • Patent number: 10160589
    Abstract: Disclosed are a biosensor strip dispensing apparatus and a strip cartridge used by being coupled thereto. The present invention enables opening of a dispensing hole and dispensing of a strip to be performed simultaneously by an open plate and a dispensing plate which move by being interlocked with each other, and thus the present invention can form a biosensor strip dispensing apparatus which enables a strip to be easily dispensed when using the strip, has a great strip protection effect due to sealing of the inner part of a body, and has a compact size. In addition, the present invention enables a strip to be upwardly pressed by an up-and-down elastic unit, while adjusting the elastic force upwardly applied by a friction elastic unit so that the amount of change in a frictional force applied between the uppermost strip and a protrusion is reduced, and thus, the present invention can form a strip cartridge by which a strip is easily dispensed.
