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.

First claim

The invention claimed is:

1. A liquid sample measurement device to which a lancet device may be removably attached, the lancet device having a skin contacting face configured to come into contact with a skin during puncturing of the skin, the liquid sample measurement device to which a biosensor may be removably attached, the biosensor having a blood sample deposited on it created by the puncturing of the skin, the liquid sample measurement device comprising:
a lancet wearing cavity configured to allow removable attachment of the lancet device;
a sensor port to which the biosensor is removably attached;
a measuring sensor configured to measure an amount of a substance in the blood sample and produce a first measurement by applying a voltage or a current to electrodes of the biosensor; and
a display configured to display the first measurement of the measuring sensor;
a lancet detector configured to detect whether or not the lancet device is attached to the liquid sample measurement device and transmit a result of the detection; and
a controller configured to control the measuring sensor, the controller also being connected to a detection sensor; and
a memory configured to record the first measurement of the measuring sensor, wherein
after the measuring sensor produces the first measurement, the controller is further configured to prevent the memory from recording the first measurement until both removal of the lancet device from the liquid sample measurement device is detected by the lancet detector and removal of the biosensor from the liquid sample measurement device is detected by the detection sensor.

2. The liquid sample measurement device according to claim 1 , wherein
after the measuring sensor produces the first measurement, the controller is further configured to prevent the measuring sensor from producing a second measurement until both replacement of the lancet device in the liquid sample measurement device is detected by the lancet detector and replacement of the biosensor in the liquid sample measurement device is detected by the detection sensor.

3. The liquid sample measurement device according to claim 1 , further comprising:
a user interface configured to accept user input of information identifying a measurer, a person to be measured, and the biosensor;
the controller further configured to associate the information identifying the measurer, the person to be measured, and the biosensor with the first measurement.

4. The liquid sample measurement device according to claim 1 , further comprising:
an ejecting lever arranged to eject the lancet device from the lancet wearing cavity.

5. The liquid sample measurement device according to claim 1 , further comprising:
a driver unit being disposed in the liquid sample measurement device, wherein
the driver unit is configured to drive the lancet device and wherein the lancet device is a disposable lancet needle cartridge.

6. The liquid sample measurement device of claim 1 , wherein
the lancet device and the biosensor are coupled together.

7. The liquid sample measurement device according to claim 1 , wherein the measuring sensor is configured to measure a second amount of a second substance in the blood sample and produce a second measurement by applying a second voltage or a second current to the electrodes of the biosensor.
