Abstract

An liquid sample measuring system includes a measuring device including a measuring section which measures biological information from liquid sample of a living subject within a housing in which a biosensor, on which the liquid sample of the biological body is deposited, is detachably mounted and a movement measuring section which measures movement information of the housing within the housing, and an administrating device including a movement determining section which determines whether or not a degree of the movement of the housing is within an allowable range by analyzing the movement information received from the measuring device.

the movement measuring section measuring movement information of the housing, and disposed inside the housing; and

an administrating device including a movement determining section,

the movement determining section comprising a processor programmed to analyze the movement information and determine whether or not an acceleration of the housing is larger than a threshold value indicating that a movement of the housing is over an allowable range, and wherein;

a display section is provided in the measurement section or the administrating device;

a biosensor is detachably mounted to the housing and the biosensor accepts a sample deposition of the liquid sample of the living subject;

the processor is further programmed to determine the acceleration of the housing during a time from when the biosensor is mounted to the housing to when measuring the biological information by the measuring section ends;

the processor is further programmed to determine whether the acceleration of the housing is within the allowable range in each of a first period, a second period, and a third period;

the first period being a first time period from a mounting of the biosensor to the sample deposition;

the second period being a second time period from the sample deposition to a start of measurement of the biological information; and

the third period being a third time period from the start of measurement to an ending of measurement of the biological information; and

the processor further programmed to display a period in which the acceleration of the housing is outside the allowable range on the display section.

2. The liquid sample measuring system according to claim 1, wherein:

the processor is further programmed to set a different allowable range for each of the first, the second, and the third periods, and

determines whether the degree of the change in the movement in each of the first, the second, and the third periods is within each respective allowable range for the first, the second, and the third periods.

3. The liquid sample measuring system according to claim 2, wherein:

the processor is further programmed to determine whether or not an allowable range of movement in a direction in which the biosensor is inserted to the housing is narrower than an allowable range of the degree of the change in the movement in other directions.

4. The liquid sample measuring system according to claim 2, wherein:

the processor is further programmed to determine whether or not an allowable range of the acceleration of the housing in a right direction and a left direction is wider than an allowable range in other directions.

5. The liquid sample measuring system according to claim 2, wherein:

the processor is further programmed to detect, in the second period, a state in which the liquid sample is not stably let to the biosensor based on the allowable range of the acceleration of the housing.

6. The liquid sample measuring system according to claim 2, wherein:

the processor is further programmed to detect, in the third period, a state in which the liquid sample does not stably exist on an electrode of the biosensor based on the allowable range of the degree of the change in the movement.

7. The liquid sample measuring system according to claim 1, further comprising:

a display section indicates that the acceleration of the housing is outside the allowable range when the processor determines that the acceleration of the housing is outside the allowable range.

8. The liquid sample measuring system according to claim 7, wherein:

the processor is further programmed to have the display further instruct a user how to handle the measuring device according to an instruction program.

9. The liquid sample measuring system according to claim 8, wherein:

the processor is further programmed to record a measurer identification;

the administrating device transmits measurer identification information to a plurality of measuring devices, and transmits the instruction program with the measurer identification information;

the measurer identification information identifying a measurer needing instruction handling the device via the instruction program; and

when the measurer identification input in a measurement by the measuring section matches a measurer identification transmitted from the administrating device, the display section displays the instruction program.

10. The liquid sample measuring system according to claim 1, wherein:

the processor is further programmed to determine whether biological information measured by the measuring section is an abnormal value;

the administrating device further transmits the biological information to an information collecting device; and

when the acceleration of the housing is within the allowable range and the biological information is an abnormal value, the administrating device transmits the biological information to the information collecting device.

11. The liquid sample measuring system according to claim 1, further comprising:

a cover detachably mounted to the housing, and covers at least a portion of the housing;

a cover detection section detects whether the cover is mounted when measuring the biological information is performed by the measuring section; and
