Abstract

A measurement device A includes a display section 10 capable of displaying measurement data obtained by measurement means 12, 13, 14a, a clock function section 16, an event time setting means 14b, 15 capable of setting the time of an event, and an elapsed time display processing means 14c that starts measurement of the elapsed time from the time of the event to the current time when the time of the event is set by the event time setting means and causes the display section 10 to display the elapsed time. With this arrangement, the user does not need to perform a troublesome task of calculating the elapsed time, and the measurement of a sample in a proper period of time after the event is promoted.

Claims

1. A measurement device comprising:

a measurement means that performs measurement on a particular component contained in a sample;

a display section capable of displaying measurement data obtained by the measurement means;

a clock function section;

an event time setting means capable of setting a time of an event related to the measurement; and

an elapsed time display processing means that starts measurement of an elapsed time from the time of the event to a current time when the time of the event is set by the event time setting means and causes the display section to display the elapsed time.

2. The measurement device according to claim 1, wherein the elapsed time is displayed on a standby screen of the display section.

3. The measurement device according to claim 1, further comprising a notification means capable of performing a notifying operation in a manner that is different from the displaying of the data by the display section,

wherein the notification means performs the notifying operation when a first predetermined period of time has elapsed from the time of the event.

4. The measurement device according to claim 1, wherein the displaying of the elapsed time is stopped when a second predetermined period of time has elapsed from the time of the event.

5. The measurement device according to claim 1, wherein:

the elapsed time display processing means calculates the elapsed time based on the time of the event and the current time clocked by the clock function section; and

the displaying of the elapsed time is stopped when the time clocked by the clock function section is changed within a period during which the elapsed time is displayed.

6. The measurement device according to claim 1, further comprising a storage means in which the measurement data obtained by the measurement means is to be stored,

wherein, when the measurement data is obtained from the measurement performed before elapse of a third predetermined period of time from the time of the event, reference data indicating to that effect is stored in the storage means as attached to the measurement data.

7. The measurement device according to claim 6, further comprising a terminal section capable of reading the measurement data obtained by the measurement means and the reference data out of the storage means and outputting the measurement data and the reference data to an external device.

8. The measurement device according to claim 1, wherein, when a predetermined operation is performed, the event time setting means regards the time when the operation is performed as the time of the event.

9. The measurement device according to claim 8, further comprising an operation switch,

wherein the predetermined operation is an operation to turn on the operation switch.

10. The measurement device according to claim 8, wherein:

the measurement means includes a sensor mount portion to which a sensor capable of retaining the sample is to be mounted, and a detection switch for detecting the mounting of the sensor to the sensor mount portion; and

the predetermined operation is an operation to mount the sensor to the sensor mount portion to cause the detection switch to detect the mounting of the sensor.

11. The measurement device according to claim 8, wherein, when the predetermined operation is performed a plurality of times, the time when the operation is performed last is regarded as the time of the event, and data having been regarded as the time of the event earlier than that time is invalidated.

12. The measurement device according to claim 1, which is provided with an edit function capable of changing at least one of a value representing the time of the event and a value representing the elapsed time by a predetermined operation.

13. The measurement device according to claim 1, which includes a case having a size allowing the case to be held with one hand, the display section being attached to the case so as to be viewable from outside,

wherein the case accommodates therein devices forming the measurement means, the clock function section, the event time setting means and the elapsed time display processing means, and entirety of the measurement device is designed as a portable measurement device.

14. The measurement device according to claim 1, wherein the measurement means, the event time setting means and the elapsed time display processing means comprise a CPU and a storage means attached to the CPU.

15. The measurement device according to claim 1, wherein the measurement means is capable of measuring a blood glucose level, and the event is a meal.
