Abstract

A puncturing apparatus includes a housing having a first case and a second case, the housing configured to move at least one of the first case and the second case so that the cases are in an overlapping state in which the first case and the second case overlap one another or a non-overlapping state. A puncturer is housed in the housing and a puncture starting mechanism, having a puncturing button, is configured to activate the puncturer. A first safety section is configured to prevent at least one of the puncturing opening and the puncturing button from being exposed, by placing the first case and the second case in the overlapping state, and a second safety section is configured to disable operation of the puncture starting mechanism in the non-overlapping state of the first case and the second case.

Claims

1. A puncturing apparatus comprising:

a housing having a first case and a second case, the housing configured to move at least one of the first case and the second case so that the cases are in an overlapping state in which the first case and the second case overlap one another, or are in a non-overlapping state;

a puncturer received in the housing, the puncturer configured to perform puncturing through a puncturing opening;

a puncture starting mechanism having a puncturing button, the puncture starting mechanism configured to activate the puncturer;

a first safety section configured to prevent exposure of at least one of the puncturing opening and the puncturing button upon movement of the first case and the second case to the overlapping state; and

a second safety section configured to disable operation of the puncture starting mechanism in the non-overlapping state of the first case and the second case,

wherein the second safety section is a pedestal having the puncturing opening, the pedestal being provided in one of the first case and the second case, and being disposed between the first case and the second case in the overlapping state, and

the pedestal is subjected to being pressed by the first case and the second case in the overlapping state so as to cover the puncturing opening with the first case or the second case, and is released from being pressed in the non-overlapping state so as to disable the operation of the puncture starting mechanism.

2. The puncturing apparatus according to claim 1, wherein the puncturer comprises a laser emitting device that punctures skin with laser light without contact.

3. The puncturing apparatus according to claim 1, wherein the puncturer comprises a needle puncturing device that punctures skin with a puncture needle.

4. The puncturing apparatus according to claim 1, wherein:

the first safety section comprises a hinge at a connection of an end of the first case and an end of the second case; and

the first case and the second case are opened and closed via the hinge.

5. The puncturing apparatus according to claim 1, wherein:

the first safety section comprises a slide on each side surface of the first case and the second case; and

the first case and the second case are slidably opened and closed through the slide.

6. The puncturing apparatus according to claim 1, wherein:

the first safety section comprises an axis at a connecting point of an end of the first case and the second case; and

the first case and the second case are pivotally opened and closed by pivoting about the axis.

7. The puncturing apparatus according to claim 1, wherein:

the second safety section is provided with a skin detecting sensor at a tip of the pedestal; and

operation of the puncture starting mechanism is enabled when the skin detecting sensor detects skin.

8. The puncturing apparatus according to claim 1, wherein:

the second safety section comprises a light receiving sensor inside the pedestal; and

operation of the puncture starting mechanism is enabled when an output of the light receiving sensor is changed.

9. The puncturing apparatus according to claim 1, wherein the second safety section is an operator that can perform a predetermined operation;

and enables the puncture starting mechanism when the operator performs the predetermined operation.

10. The puncturing apparatus according to claim 9, wherein the operator inputs a pressing order of a plurality of buttons as operation information.

11. The puncturing apparatus according to claim 9, wherein the operator inputs, as operation information, one of rotation of a knob registered in advance;

operation of a pointing device registered in advance;

rotation of a volume registered in advance;

operation of a trackball registered in advance; and

operation of a dip switch registered in advance.

12. The puncturing apparatus according to claim 1, wherein:

the second safety section is a fingerprint identifier that identifies a pre-stored fingerprint; and

the puncture starting mechanism is enabled when the fingerprint identifier identifies the pre-stored fingerprint.

13. The puncturing apparatus according to claim 1, further comprising a multiple-stage opening and closing mechanism configured to lock opening and closing operation of the first case and the second case between the overlapping state and the non-overlapping state,

wherein the puncture starting mechanism is enabled when the multiple-stage opening and closing mechanism locks the opening and closing operation between the overlapping state and the non-overlapping state.

14. The puncturing apparatus according to claim 13, wherein a locked position by the multiple stage opening and closing mechanism is a position where puncturing from the puncturing opening provided in the first case is blocked by the second case facing the first case.

15. The puncturing apparatus according to claim 1, further comprising an inner cover between the first case and the second case,

wherein the inner cover blocks puncturing from the puncturing opening provided in the housing.

16. The puncturing apparatus according to claim 15, wherein the inner cover is provided in one of the first case and the second case.

17. The puncturing apparatus according to claim 15, wherein the inner cover is provided separately from the first case and the second case.

18. A blood test apparatus comprising:

a puncturing apparatus that punctures skin and tests components of blood exuding from the skin by puncturing,

wherein the puncturing apparatus comprises a puncturing apparatus according to claim 1.

19. The blood test apparatus according to claim 18, further comprising a negative pressure section that applies a negative pressure to a vicinity of the skin punctured by the puncturing apparatus.

20. The puncturing apparatus according to claim 1, wherein the puncturing opening is provided on a main surface of the first case which faces the second case in the overlapping state of the first case and the second case.

21. The puncturing apparatus according to claim 1, wherein the pedestal is distinct from the puncturing button.
