Abstract

This liquid sample measurement device is provided with: a lancet mounting part to and from which a lancet device having a skin contact section for puncturing skin can be attached and detached; a sensor mounting part to which a biosensor, which is spotted with blood that comes out from the punctured skin, can be attached; and a measurement part that uses the biosensor attached to the sensor mounting part to measure the amounts of substances in the blood. The liquid sample measurement device includes a feature that makes it necessary to replace a lancet device that has been attached to the lance mounting part and has punctured skin, each time a lancet device is used to puncture skin.

Claims

1. A liquid sample measurement device, comprising:

a lancet device that is replaceable, the lancet device including a skin contacting part configured to puncture a skin;

a lancet wearing part to which the lancet device is removably attached;

a biosensor configured to accept a blood sample from the skin;

a sensor wearing part to which the biosensor is removably attached;

a measuring section which measures an amount of a substance in the blood sample using the biosensor; and

the lancet device must be replaced after it has punctured the skin.

2. The liquid sample measurement device according to claim 1, further comprising:

a controller which controls the measuring section, the controller preventing the measuring section from performing a second measurement until the lancet device is replaced after the measuring section performs a first measurement.

3. The liquid sample measurement device according to claim 2, further comprising:

a recording section which records a result of measuring by the measuring section, wherein

the controller prevents the recording section from recording a result of the first measurement until the biosensor and the lancet device are replaced.

4. The liquid sample measurement device according to claim 3, further comprising:

an input section to which information identifying a measurer, a person to be measured, and the biosensor is inputted;

wherein the controller associates the information with the result of the first measurement.

5. The liquid sample measurement device according to claim 2, further comprising:

a display section which displays the result of the first measurement,

wherein the controller controls the display section to display the result of the first measurement and display a recommendation to replace the lancet device and the biosensor, and

the display section displays the recommendation until the lancet device and the biosensor are replaced.

6. The liquid sample measurement device according to claim 2, wherein:

the lancet wearing part includes a lancet wearing detecting section which detects whether or not the lancet device is attached, and the lancet wearing part generates a signal indicating whether or not the lancet device is attached; and

the controller determines whether or not the lancet device is ejected based on the signal from the lancet wearing detecting section.

7. The liquid sample measurement device according to claim 2, wherein:

the sensor wearing part includes a sensor wearing detecting section which detects whether or not the biosensor is attached, and the sensor wearing part generates a signal indicating whether or not the biosensor is attached; and

the controller determines whether or not the biosensor is ejected based on the signal from the sensor wearing detecting section.

8. The liquid sample measurement device according to claim 1, further comprising:

an ejecting lever which ejects the lancet device from the lancet wearing part.

9. The liquid sample measurement device according to claim 1, wherein:

the lancet device is disposable and includes a drive unit, the drive unit embedded in the lancet device and enabling the skin contacting portion to puncture the skin.

10. The liquid sample measurement device according to claim 1, further comprising:

a device main body;

a drive unit disposed in the device main body, the drive unit configured to drive the lancet needle cartridge; and

the lancet device is a disposable lancet needle cartridge.
