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.

Claims

1. A biosensor strip dispensing apparatus comprising:

a body configured to accommodate at least one biosensor strip therein, and having a dispensing port formed in a front portion thereof to dispense the biosensor strip through the dispensing port;

a sealing lever provided with a covering piece to shield the dispensing port, the covering piece configured to rotate about a first rotation shaft in (i) an opening direction, in which the covering piece opens the dispensing port, and (ii) a shielding direction that is opposite to the opening direction;

an opening plate connected to or supporting the sealing lever to rotate the sealing lever in the opening direction and the shielding direction while being slid back and forth on the body;

a dispensing plate interlocked with the opening plate to be slid in the same direction as the opening plate, the dispensing plate being configured to push the biosensor strip forward at a rear side of the biosensor strip;

a first elastic unit made of an elastic body and configured to elastically support the sealing lever in the opening direction,

wherein the sealing lever includes;

a front arm extending forward from the first rotation shaft, and connected to the covering piece, which is bent downwardly, at a front end thereof;

a rear arm extending rearwardly from the first rotation shaft; and

an adjustment projection bent downwardly at a rear end of the rear arm, and

wherein the opening plate includes;

a front end portion configured to support a lower end of the adjustment projection in a state where the covering piece shields the dispensing port; and

a central portion extending rearwardly from the front end portion and formed to be lower than the front end portion, the central portion being configured to support the lower end of the adjustment projection in a where the covering piece opens the dispensing port.

2. The biosensor strip dispensing apparatus of claim 1, further comprising a packing, wherein the packing is coupled to the covering piece to seal the dispensing port.

3. The biosensor strip dispensing apparatus of claim 1, wherein the opening plate includes an inclined portion that connects the front end portion and the central portion to each other and supports the lower end of the adjustment projection.

4. The biosensor strip dispensing apparatus of claim 1, wherein multiple biosensor strips are provided and stacked one on another within a cartridge,

the body includes a storage hole formed to accommodate the cartridge, and

the biosensor strip dispensing apparatus further comprises:

a door rotatably coupled to the body to open and close the storage hole; and

a second elastic unit made of an elastic body to elastically support the door in a direction where the door shields the storage hole.

5. The biosensor strip dispensing apparatus of claim 1, further comprising:

a drive motor; and

a gear assembly connecting the drive motor to the opening plate and the dispensing plate.

6. The biosensor strip dispensing apparatus of claim 5, wherein the opening plate is positioned outside the body,

the dispensing plate is positioned inside the body, and

the gear assembly includes a first gear rotated via a connection to the opening plate and a second gear rotated via a connection to the dispensing plate.

7. The biosensor strip dispensing apparatus of claim 1, further comprising:

an abutment configured to support a lower surface of the biosensor strip when the biosensor strip is dispensed; and

a contact terminal configured to support an upper surface of the biosensor strip when the biosensor strip is dispensed, and electrically connected to an electrode of the biosensor strip.

8. The biosensor strip dispensing apparatus of claim 7, wherein the contact terminal is coupled to the body to be rotatable about a third rotation shaft, and

the biosensor strip dispensing apparatus further comprises:

an elastic unit made of an elastic body to elastically support the contact terminal in a direction where the contact terminal supports the strip.

9. The biosensor strip dispensing apparatus of claim 8, wherein the contact terminal includes a pushing surface formed to be inclined along the third rotation shaft, and

the biosensor strip dispensing apparatus further comprises:

a release button configured to move back and forth with respect to the pushing surface in a direction parallel to the third rotation shaft.
