In this case, the sensor mounting cartridge 220 is configured such that the measurement sensor unit 210 is mounted on the sensor mounting cartridge 220, as shown in FIG. 2. It is preferable to further include a sensor-mounted through hole 221 formed on the circumference.

Next, the replacement drive unit 300 will be described. The replacement driving unit 300 is installed in the main body 100, and the measurement sensor unit 210 is positioned in a usable measurement state where the unused measurement sensor unit 210 is operated according to the operation of the push button 102. It is configured to operate the sensor mounting cartridge 220 in order to be moved sequentially to replace).

Embodiments constituting the replacement driving unit 300 capable of such an operation may also be implemented in a wide variety of embodiments. In one embodiment, when the measurement sensor unit 200 is implemented similarly to the magazine structure of the revolver type pistol, the sensor mounting cartridge 220 is centered on the cartridge mounting hole 222 as shown in FIG. 2. The sensor mounting through the circumference 221 is continuously formed as the number of, one side is preferably configured to further include a rotation drive projection 223 is composed of a downward inclined surface and the other side is composed of a vertical surface. .

In this case, as shown in FIGS. 3 and 5, the replacement driving unit 300 may include a vertical driving rod 310 and a rotation driving cam arm 320. 3 and 5, the up and down drive rod 310 is operated up and down in conjunction with the push button 102, the lower end of the sensor so that the mounting end portion 212 can be inserted and supported during the lower operation The mounting part 312 is formed. As described above, the vertical drive rod 310 and the push button 102 are integrally formed as shown in FIG. 3 to implement the vertical drive rod 310 interlocked with the push button 102. It is possible to be configured, of course, it is also possible to be configured such that the upper surface of the up and down drive rods 310 each having an elastic return means in direct contact with the lower surface of the push button 102.

Meanwhile, as shown in FIGS. 2 and 5, the rotation driving cam arm 320 pushes one rotation driving protrusion 223 to the side per one lowering operation of the vertical driving rod 310 to the sensor mounting cartridge. And to rotate 220.

That is, as shown in (A) of FIG. 5, while the vertical driving rod 310 descends once, the contact side 322 of the rotation driving cam arm 320 is positioned on the side of the vertical driving rod 310. It is pushed laterally by the cam arm drive protrusion 311 formed. Accordingly, the rotation drive cam arm 320 is rotated while the cam arm rotation shaft 321 on the upper side of the rotation drive cam arm 320 is rotated, so that the rotation drive protrusion 323 formed below the rotation drive cam arm 320. The other side of the vertical surface of the rotation driving projection 223 is pushed out in the lateral direction. As a result, as shown in FIG. 5B, the sensor mounting cartridge 220 rotates about the cartridge mounting hole 222 as the rotation center.

On the other hand, the rotation drive projection 223 is formed continuously on the circumference around the cartridge mounting hole 222 as described above as the number of the sensor mounting hole 221 (that is, the sensor mounting hole ( Six 221 rotational driving protrusions 223 are also formed if six, and the sensor mounting hole 221 ten rotational driving projections 223 are also formed.), The rotational drive cam arm 320 When one of the rotary drive projections 223 is pushed out and moved so that the sensor mounting cartridge 220 is rotated, the degree of rotation is the separation angle between the cartridge mounting holes 222 adjacent to each other exactly as shown in FIG. rotate by (θ).

Therefore, each time the vertical driving rod 310 is lowered once, the sensor mounting cartridge 220 is rotated by the separation angle θ, and as a result, the measurement sensor unit 210 is not used. The measurement sensor unit 210 can be moved and replaced sequentially so as to be in this usable measurement state (A).

On the other hand, the up and down drive rod 310 as shown in (C) in Figure 5, while moving down the sensor mounting cartridge 220 by moving the rotation angle by the separation angle (θ) the unused measuring sensor unit 210 ) And the sensor probe 211 of the unused measuring sensor unit 210 positioned in the measuring state A continues to descend even after allowing the to be placed in the usable measuring state A. (111) The measurement sensor unit 210 is pushed down to be exposed to the outside so as to extract the user's blood and the like.

In this case, the up-and-down driving rod 310 is connected to the sensor mounting part 312 so that the measurement signal transmitted from the sensor probe 211 can be transmitted to the blood glucose measurement part 500. And a connector electrode part which is formed in contact with the signal transmission electrode part 213 and receives an electrical signal transmitted from the sensor probe part 211 when the mounting end part 212 is inserted into and supported by the sensor mounting part 312. It is preferable that it is comprised including 313 further.

On the other hand, in consideration of contamination and safety issues while enabling repeated operation, it is preferable that the measurement sensor unit 210 is raised again to be returned to the sensor mounting cartridge 220 when one measurement is completed. . To this end, as shown in FIG. 2, the vertical drive rod 310 may further include a vertical drive rod return elastic means 315, which may be embodied by a spring or the like, to enable the upward operation for the return. . On the other hand, when the vertical drive rod return elastic means 315 is configured to operate in conjunction with the push button 102, the upward operation for the return of the push button 102 is It also functions as a push button return elastic means 103 to enable it. On the other hand, in the case of having the automatic lift drive unit 400 to be described later, the push button return elastic means 103 to enable the lift operation for the return of the push button 102, as shown in FIG. It is preferable that the driving rod return elastic means 315 be further provided.

In addition, by using the operation of the up and down drive rod 310 that rises in conjunction with the operation of the push button 102, the measurement sensor unit 210 is raised together as shown in FIG. In order to be mounted on the sensor mounting cartridge 220 to be mounted, the lower end of the mounting distal end 212 of the measurement sensor unit 210 may further include a fastening groove 214 as shown in FIG. 4. In this case, as shown in FIGS. 3 and 5, the mounting end portion 212 is inserted into and supported by the sensor mounting portion 312 at the lower end of the up and down driving rod 310 to the fastening groove 214. It is preferable to further form the sensor unit detachable elastic protrusion 314 to be temporarily elastically coupled. Meanwhile, as shown in FIG. 4, when the measurement sensor unit 210 is mounted and mounted on the sensor mounting cartridge 220, the measurement sensor unit 210 moves upward in the measurement sensor unit 210. It is preferable that a stopper 215 is further formed to block the gap.

The sensor unit detachable elastic protrusion 314 may be inserted into the sensor mounting portion 312 while the mounting end portion 212 is drawn into the sensor mounting portion 312 while the vertical driving rod 310 descends as shown in (C) of FIG. 5. Inserted into the fastening groove 214 is coupled.

On the other hand, when the up-and-down driving rod 310 is raised after one blood glucose measurement is completed, the sensor unit detachable elastic protrusion 314 is inserted into the fastening groove 214 and fastened, so that the measurement sensor unit 210 As shown in (C) of Figure 5 is raised with the up and down driving rod 310 is returned to the sensor mounting cartridge 220 is mounted. In this case, the up and down driving rod 310 is raised as shown in (E) in FIG. 5 to return to the initial position, and in this additional raising process by the stopper 215 the measurement sensor unit ( Since the further rise of the 210 is prevented, the sensor unit detachable elastic protrusion 314 is released from the fastening groove 214 and the fastening of the vertical driving rod 310 and the measurement sensor unit 210 is released. The vertical driving rod 310 is further raised alone to return to the initial position. Therefore, even when the sensor mounting cartridge 220 rotates during the next operation, the vertical driving rod 310 does not interfere with the moving measurement sensor unit 210.

On the other hand, in order to reduce the pain of the user and efficient measurement, the sensor probe 211 is preferably invaded into the user's body for a short time (usually within 0.3 ~ 1 second) and then return again. However, it is extremely difficult for the user to complete the operation of the push button 102 in such a short time. Therefore, after the up and down driving rod 310 is operated in descending operation in conjunction with the lowering operation of the push button 102, the up and down driving rod 310 further includes an automatic raising driving unit 400 for automatically raising and operating. It is preferable to be configured.

In this case, as an embodiment of implementing the automatic lift driver 400, a wide variety of embodiments are possible. As an embodiment of implementing the automatic lift driver 400, the automatic lift driver 400 has a lower end as shown in FIG. 7. It is formed to be continuous to the side of the up and down driving rod 310 is configured to project in an oblique direction upwards, the upper end of the elastic support arm 410 in contact with the lower end of the push button 102, and the main body 100 It is preferably configured to further include a guide protrusion 420 is installed in the) is configured to contact support the bottom outer surface of the elastic support arm (410). In this case, the upper side of the up and down driving rod 310 is directly at the lower end of the push button 102, unlike the case in which the up and down driving rod 310 and the push button 102 are simply interlocked together. 7, only the upper end of the elastic support arm 410 is configured to contact the lower end of the push button 102 as shown in FIG. 7.

According to this configuration, as shown in (A) of FIG. 7, in the descending step of the push button 102, the up and down drive rod 310 descends together with the push button 102. In this descending process, the elastic support arm 410 is gradually folded toward the up and down driving rod 310 by the guide protrusion 420. Thereafter, as shown in (B) of FIG. 7, when the vertical driving rod 310 descends to the maximum, the upper side of the elastic support arm 410 folded to the maximum is separated from the lower side of the push button 102. do. Therefore, even when the push button 102 is pressed, the up and down driving rod 310 is moved up by the elasticity of the up and down driving rod return elastic means 315 as shown in (C) of FIG. 7 to the initial position. It will automatically return. In this case, the elastic support arm 410 is pressed by the side of the push button 102 to maintain the folded state in the vertical drive rod 310 direction. In this process, the measurement sensor unit 310 operated in conjunction with the vertical drive rod 310 is also automatically raised and returned together, so that the sensor probe 211 is short for a short time (usually within 0.3 to 1 second). It is only possible to invade the user's body for a while and then automatically return to it again.

After that, when the user releases the push button 102, the push button return elastic means 103 raises the push button 102 to an initial position as shown in (D) in FIG. The upper side of the elastic support arm 410 is lowered only when the elastic support arm 410 is pushed back by the side of the push button 102 and folded in the direction of the vertical driving rod 310. Returning to the initial state in contact with the distal end allows for repeated next operation.

On the other hand, in the case where all the measurement sensor units 210 are used by repeating the measurement operation, in order to prevent reuse of the already used measurement sensor unit 210, the sensor mounting cartridge 220 is shown in FIGS. 2 and 3. As shown, the anti-reuse protrusion 224 is further formed, and when the sensor mounting cartridge 220 is rotated once in the main body 100, the sensor-mounting cartridge 220 is brought into contact with the reuse prevention protrusion 224. It is preferable that a reuse prevention projection stopper 104 is further formed to limit the rotational operation of the projection. In this case, when all the measurement sensor units 210 are used as shown in (B) in FIG. 6 (wherein, the measurement sensor units 210 used are indicated by dark colors). The rotational operation of 220 becomes impossible. Therefore, as described above, when the push button 102 is pressed, the rotation operation of the sensor mounting cartridge 220 which is performed first is impossible, and thus the rotation driving cam arm 320 is not operated. Therefore, the up and down drive rod 320 cannot be lowered due to the rotation drive cam arm 320, and the push button 102 is also not pressed. Thus, the user can immediately know that all the measurement sensor units 210 have already been used by the push button 102 not being pressed, and replace the new sensor mounting cartridge 220 with the new measurement sensor units 210 mounted.
