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 section configured to measure a particular component contained in a sample;

a clock section configured to clock time;

a sensor mount section, to which a sensor configured to retain the sample is to be mounted, the sensor mount section including a detection switch configured to detect a mounting of the sensor to the sensor mount section;

an event time recording section configured to record an event time; and

a display section configured to display measurement data obtained by a measurement conducted by the measurement device, and the display section also being configured to display an elapsed time, the elapsed time being time between the event time and a current time clocked by the clock

wherein, when a predetermined operation is performed, the event time recording section regards the time when the predetermined operation is performed as the event time,

the predetermined operation includes an operation of mounting the sensor to the sensor mount section and causing the detection switch to detect the mounting of the sensor, and

the event time recording section is configured to be switchable between an event time recording ON mode in which the recording of the event time by detecting the mounting of the sensor is possible and an event time recording OFF mode in which the recording of the event time by detecting the mounting of the sensor is impossible.

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 section configured to perform a notifying operation in a manner that is different from the displaying of the data by the display section,

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

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 event time.

5. The measurement device according to claim 1, further comprising

a storage section in which the measurement data obtained by the measurement section 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 event time, reference data indicating to that effect is stored in the storage section as attached to the measurement data.

6. The measurement device according to claim 5, further comprising

a terminal section configured to read the measurement data obtained by the measurement section and the reference data out of the storage section and outputting the measurement data and the reference data to an external device.

7. The measurement device according to claim 1, further comprising an operation switch, wherein the predetermined operation is an operation to turn on the operation switch.

8. The measurement device according to claim 1, wherein, when the predetermined operation is performed a plurality of times, the time when the operation is performed last is regarded as the event time, and data having been regarded as the event time of an earlier event is invalidated.

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

10. 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 section, the clock section, the event time recording section and the display section, and entirety of the measurement device is designed as a portable measurement device.

11. The measurement device according to claim 1, wherein the measurement section, the event time recording section and the display section comprise a CPU and a storage section attached to the CPU.

12. The measurement device according to claim 1, wherein the measurement section is configured to measure a blood glucose level.

14. The measurement device according to claim 1, wherein the event time recording section is configured to record a second event time, the second event time being an operation of an operation switch.

13. A measurement device comprising:

measurement means for measuring a particular component contained in a sample;

clock means for clocking time;

sensor mount means for detecting a mounting of a sensor, the sensor mount means being configured to have the sensor mounted thereto, the sensor mount means including a detection means for detecting a mounting of the sensor to the sensor mount means, the sensor being configured to retain the sample;

event time recording means for recording an event time; and

a display means for displaying measurement data obtained by a measurement conducted by the measurement means and for displaying an elapsed time, the elapsed time being time between the event time and a current time clocked by the clock means,

wherein, when a predetermined operation is performed, the event time recording means regards the time when the predetermined operation is performed as the event time,

the predetermined operation includes an operation to mount the sensor to the sensor mount means to cause the sensor mount means to detect the mounting of the sensor, and

the event time recording means is configured to be switchable between an event time recording ON mode in which the recording of the event time by detecting the mounting of the sensor is possible and an event time recording OFF mode in which the recording of the event time by detecting the mounting of the sensor is impossible.
