LANCET-INTEGRATED SENSOR, MEASURING DEVICE FOR LANCET-INTEGRATED SENSOR, AND CARTRIDGE
A sensor and a lancet are integrated with each other. A thin strip-shaped sensor and a lancet are integrated so that the lancet moves in parallel, along a longitudinal direction of the sensor. A measuring device to which an integrated lancet and sensor is attached is provided with a function of driving the attached lancet.

53 . A measuring device for performing measurement using a lancet-integrated sensor that is attached thereto, said lancet-integrated sensor being constituted by integrating a lancet for lancing skin to collect bodily fluid, and a sensor for analyzing the extracted bodily fluid, said measuring device including:
a drive means for driving the lancet in a direction in which the lancet lances the skin, along the longitudinal direction of the sensor, from the standby position of the lancet;
wherein, after the drive means has driven the lancet in the direction in which the lancet lances the skin, the drive means can drive the lancet back to the standby position while maintaining the state where the lancet-integrated sensor is attached to the measuring device.
54 . A measuring device for a lancet-integrated sensor as defined in claim 53 , wherein
the drive means has a shaft to which a connector receiver is fixed at an end on the side where the lancet lances the skin, which connector receiver receives an end of the lancet on the side opposite to the side where the lancet lances the skin;
a pull stick for driving the lancet back in a direction opposite to the direction in which the lancet lances the skin is disposed on an end of the shaft on the side opposite to the side where the lancet lances the skin; and
the connector receiver is provided with a claw portion which is unlocked by pressing an operation button to start the operation of the drive means, and stops the motion of the connector receiver against a force applied by a spring that is provided on the shaft to move the connector receiver in the direction in which the lancet lances the skin.
55 . A measuring device for a lancet-integrated sensor as defined in claim 54 , wherein
the measuring device has, in its internal cavity, a support member for slidably supporting the shaft in the vicinity of its center; and
the spring is a coil spring which is placed between the support member of the shaft and the connector receiver.
56 . A measuring device for a lancet-integrated sensor as defined in claim 54 , wherein
the pull stick has an opening which is formed at an end of the side where the lancet lances the skin;
an end of the shaft on the side opposite to the side where the lancet lances the skin is slidably housed in the pull stick through the opening; and
the end of the shaft on the side opposite to the side where the lancet lances the skin has a slip-out prevention member for preventing the end of the shaft to slipping out of the pull stick toward the side where the lancet lances the skin.
57 . A measuring device for a lancet-integrated sensor as defined in claim 54 , wherein
the driving means is provided with a lancet projection amount adjuster for adjusting the amount of projection of the needle of the lancet that lances the skin, which driving means is placed between the measuring device and the pull stick.
58 . A measuring device for a lancet-integrated sensor as defined in claim 57 , wherein
the pull stick is approximately cylindrical in shape, and an end of the pull stick on the side opposite to the side where the lancet lances the skin has a handle part having a portion of a diameter larger than the diameter of the cylindrical part;
the lancet projection amount adjuster is approximately cylindrical in shape, and an end of the adjuster on the side opposite to the side where the lancet lances the skin has an opening having a diameter equal to the diameter of the cylindrical part of the pull stick; and
the cylindrical part is slidably housed through the opening, and the cylindrical part is screwed into a screw hole that is formed on a side surface of the measuring device on the side opposite to the side where the lancet lances the skin, toward the inside of the measuring device, whereby the cylindrical part rotates in the screw direction or in the opposite direction to adjust the amount of projection of the lancet.
