Blood collection depth control device 1 according to the present invention comprises a strip withdrawal unit 10, the supply lever 20, the control unit 30 and the launch device (50). The strip 40 is a portion to which blood is absorbed or adsorbed, is a means for measuring blood glucose through photometry or electrochemical measurement, and is applied to a blood glucose meter for measuring blood glucose of a diabetic patient. ) Is built into the blood glucose meter and automatically protrudes to the outside.

The strip 40 is fixed or embedded in one side of the strip lead-out unit 10 and is drawn out forward by the drive of the drive motor 80. That is, when the blood sampling depth control device 1 according to the present invention constitutes a blood glucose measurement device, the strip 40 is stored inside the blood sugar measurement device in a state before the blood glucose measurement, and is taken out of the blood glucose measurement device when the measurement is made. Will be.

The supply lever 20 is coupled to one side of the strip lead-out part 10 and slides in the front-rear direction with respect to the strip lead-out part 10. The movement of the supply lever 20 is made by the rotation of the drive motor 80, that is, the rotational movement of the drive motor 80 is transferred to the supply lever 20 while being converted into a linear movement. To this end, a plurality of combined gears 70 may be provided, and the connection of the gears 70 and the supply lever 20 may have a structure such as a conventional rack and pinion.

The supply lever 20 is formed with a stop arm 21 protruding in a direction orthogonal to the moving direction of the strip 40. The stop arm 21 serves as a stopper when the launcher 50 moves, and stops one side of the launcher 50 from moving forward over a predetermined range.

The above-described movement of the strip 40 is made at the same time as the movement of the supply lever 20, wherein the means for the forward and backward movement of the strip 40 can be made the same as the means for the movement of the supply lever 20, Or separately.

In the former case, the strip 40 is fixed or coupled to one side of the supply lever 20 to slide forward and backward with the supply lever 20, or the strip 40 is not coupled to the supply lever 20 itself. The power according to the rotational motion of the drive motor 80 may be converted to a linear motion and then transmitted to the strip 40 and the supply lever 20, respectively.
