Abstract

A puncture device which punctures a skin of a subject for extracting a tissue fluid from a puncture site of the subject. The puncture device included a timer; a notifying section which notifies a user that specific time measured by the time has passed; a puncture mechanism which punctuates the skin; and an interlock mechanism which caused the timer to start time measurement in conjunction with a punctuate action by the puncture mechanism.

Claims

1. A puncture device which punctures a skin of a subject for extracting a tissue fluid from a puncture site of the subject, comprising:

a timer;

a notifying section which notifies a user that specific time measured by the timer has passed;

a puncture mechanism which punctures the skin; and

an interlock mechanism which causes the timer to start time measurement in conjunction with a puncture action by the puncture mechanism.

2. The puncture device according to claim 1,

wherein the notifying section comprises at least one of an alarm sound generator and a vibrator.

3. The puncture device according to claim 2, further comprising a notification selecting section for selecting a notifying method by the notifying section.

4. The puncture device according to claim 1, further comprising:

a main body accommodating the puncture mechanism; and

a timer unit removably mounted on the main body, and accommodating the timer and the notifying section.

5. The puncture device according to claim 4, further comprising a lock mechanism which inhibits the puncture action by the puncture mechanism when the timer unit has been removed from the main body.

6. The puncture device according to claim 5,

wherein the lock mechanism allows the puncture action by the puncture mechanism when the timer unit has been mounted on the main body.

7. The puncture device according to claim 1, further comprising a press button which is pressed by the user for causing the puncture mechanism to start the puncture action,

wherein the interlock mechanism causes the timer to start the time measurement in conjunction with a pressing action of the press button by the user.

8. The puncture device according to claim 1, further comprising:

a memory; and

a terminal for transferring from outside to the memory at least one of measurement information on measurement of a specific component in the tissue fluid of the subject and subject information on the subject, and for transferring at least one of the measurement information and the subject information which are memorized in the memory to outside.

9. The puncture device according to claim 1, further comprising a display section which displays at least one of remaining time before the specific time passes and clock time when the specific time passes.

10. The puncture device according to claim 9, further comprising a display selecting section for selecting an object to be displayed on the display section.

11. The puncture device according to claim 9, further comprising a turn-on mechanism which turns on a power supply of the display section in conjunction with an action of loading on the puncture mechanism a puncture needle for puncturing the skin.

12. An in vivo component measurement system comprising:

a puncture device which punctures a skin of a subject for extracting a tissue fluid from a puncture site of the subject, comprising;

a timer;

a notifying section which notifies a user that time measured by the timer has passed through the specific time;

a puncture mechanism which punctures the skin; and

an interlock mechanism which causes the timer to start time measurement in conjunction with a puncture action by the puncture mechanism;

a collection member for accumulating a specific component in the tissue fluid extracted from the puncture site punctured by the puncture device; and

a measurement device for obtaining a value related to a quantity of the specific component accumulated in the collection member.

13. The in vivo component measurement system according to claim 12,

wherein the specific component is glucose.

14. The in vivo component measurement system according to claim 12,

wherein the measurement device further comprises an analysis unit which obtains a value corresponding to an area under blood concentration—

time curve (AUC) of the specific component during the specific time based on a value related to the specific component.

15. The in vivo component measurement system according to claim 12,

wherein the collection member comprises an extraction medium for accumulating the specific component in the tissue fluid and a retention member for retaining the extraction medium.

16. The in vivo component measurement system according to claim 15,

wherein the extraction medium is gel.
