Abstract

To provide a puncture device in which a puncture needle is stuck into a predetermined region certainly and an indwelling device can be indwelled, the puncture device is provided for puncturing skin (dermis) by a puncture needle. This puncture device is provided with a puncture needle, an indwelling device indwelled in the skin by the puncture needle, a skin deforming mechanism for deforming the skin which is provided with a fixing portion having a space in an inside constituted by a bottom face portion and a peripheral wall portion 5b. In addition, an insertion portion for inserting the puncture needle is formed at the peripheral wall portion, the puncture needle is inserted from the insertion portion, and the skin deformed into the space by the skin deforming mechanism is adapted to be punctured.

Claims

1. in puncture device puncturing a skin by a puncture needle, the puncture device comprising:

a puncture needle;

an indwelling device indwelled in the skin by said puncture needle;

a skin deforming means for deforming the skin which is provided with a fixing portion having a space in an inside constituted by a bottom face portion and a peripheral wall portion, wherein

an insertion portion for inserting the puncture needle is formed at said peripheral wall portion,

said puncture needle is inserted from said insertion portion, and

the skin deformed into said space by said skin deforming means is to be punctured.

2. The puncture device according to claim 1, wherein said skin deforming means makes deformation so as to uplift said skin.

3. The puncture device according to claim 1, wherein said skin deforming means makes deformation so as to push down said skin.

4. The puncture device according to claim 1, wherein a retaining portion for retaining and fixing the indwelling device is formed at said peripheral wall portion.

5. The puncture device according to claim 4, wherein said retaining portion is formed at a position which becomes symmetrical to said insertion portion.

6. The puncture device according to claim 1, wherein said indwelling device is a catheter.

7. The puncture device according to claim 6, wherein said catheter has at least more than one medical agent supplying opening.

8. The puncture device according to claim 1, wherein said indwelling device is a catheter type detection sensor.

9. In a puncture device puncturing a skin by a puncture needle, the puncture device comprising:

a puncture needle;

an indwelling device indwelled in the skin by said puncture needle;

a fixing portion having a space inside and being constituted by a bottom face portion and a peripheral wall portion; and

a suction means for sucking air of said space, wherein

an insertion opening for inserting the puncture needle is formed at said peripheral wall portion,

said skin is uplifted into said space using said suction means by sucking the air of said space and by depressurizing said space,

said puncture needle is inserted from said insertion opening, and

said uplifted skin is to be punctured.

10. In a puncturing method puncturing a skin by a puncture needle, the puncturing method using:

a puncture needle;

an indwelling device indwelled in the skin by said puncture needle;

a fixing portion having a space in the inside and constituted by a bottom face portion and a peripheral wall portion; and

a skin deforming means for deforming the skin, wherein

said puncture needle is inserted into an insertion portion formed at said peripheral wall portion for inserting a puncture needle, and the skin deformed into said space by said skin deforming means is to be punctured.
