Accordingly, even though omitted below, the above description of the strip insertion error preventing device illustrated in FIG. 1 is also applied to the strip insertion error prevention method according to the present embodiment.

In step 400, the strip insertion error prevention device determines whether one end of the strip is inserted. As a result of the determination, if it is determined that one end of the strip has been inserted, the process proceeds to step 410, and if it is determined that the strip has not been inserted, the process proceeds to step 420.

In step 400, whether the strip is inserted may be determined by detecting that one end of the strip 150 is inserted into the housing 140 when the first detection unit 110 is pressed by the strip 150.

In step 410, the strip insertion error prevention device determines whether the other end of the strip is inserted. As a result of the determination, if it is determined that the other end of the strip is inserted, the process proceeds to step 430, and if it is determined that the strip is not inserted, the process proceeds to step 420.

In step 410, whether the strip is inserted may be determined by detecting that the other end of the strip 150 is inserted when the second detection unit 120 is pressed by the strip 150.

When the strip 150 is inserted into the housing 140, one end of the strip 150 spans the second protrusion 125, and when the other end of the strip 150 touches the inner vertical surface, the strip 150 The second sensing unit 120 is mounted using the angle formed by the lower surface and the strip mounting surface of the housing 140 and the distance from the strip mounting surface of the housing 140 to the uppermost end of the second sensing unit 120. The position on the plane can be determined.

In step 420, the strip insertion error prevention device displays a strip insertion error indicating that the strip 150 is incorrectly inserted into the housing on the display device.

In step 430, the strip insertion error prevention device checks whether the strip 150 is used from the NFC chip included in the strip 150.

The device for preventing a strip insertion error according to the present exemplary embodiment may record whether the strip is used by changing flag information stored in an NFC chip included in the strip when blood is injected from the strip.

As a result of checking in step 430, if a strip that has not been used proceeds to step 440, and if a strip that has been used proceeds to step 435, the used strip is output to the display device.

In step 440, the strip insertion error prevention device checks the validity period from the NFC chip included in the strip 150.

As a result of checking in step 440, if it is within the expiration date, the process proceeds to step 450, and if the expiration date has elapsed, the process proceeds to step 445, and the display device displays the strip having the expiration date.

In step 450, since it is determined that the inserted strip 150 is an unused strip and is within the expiration date, blood is injected from the strip 150.

In step 460, the strip insertion error prevention device writes the test result of the injected blood to the NFC chip, and changes whether the strip 150 is used or not.

In addition to recording the blood test result on the NFC chip, it is preferable to manage the test result by transmitting it to a database through a separate transmission unit.
