Abstract

The present invention provides a puncture device and an administration device in which a puncture needle can be stuck certainly to a predetermined region of a skin. The puncture device and the administration device of the present invention are provided with a puncture needle moving means for retaining aforesaid puncture needle to be movable and a skin deforming means for deforming the skin, wherein it is constituted such that the puncture needle is moved by aforesaid puncture needle moving means and punctures the skin deformed by aforesaid skin deforming means.

Claims

1. A puncture device for puncturing skin with a puncture needle, the puncture device comprising:

retaining means for holding the puncture needle;

a fixing portion movably supporting the retaining means and possessing a flat contact surface to be fixed to a body surface;

a positioning portion to which the fixing portion is rotatably connected and which possesses a flat surface to be fixed to the body surface;

wherein in a state in which the positioning portion is fixed to the body surface, the fixing portion is configured to be rotated from a position where the flat contact surface of the fixing portion is approximately orthogonal to the flat surface of the positioning portion toward a body surface side to raise the skin of the body surface where the flat surface of the positioning portion is fixed; and

the retaining means being configured to be moved to puncture the raised skin with the puncture needle passing through an opening window provided at an end of a positioning portion side part of the fixing portion.

2. The puncture device according to claim 1, wherein the fixing portion comprises a depressing surface adapted to be fixed to the body surface together with the positioning portion when the flat contact surface of the fixing portion is approximately orthogonal to the flat surface of the positioning portion, the depressing surface depressing the body surface where the depressing surface is fixed when the fixing portion is rotated toward the body surface side to raise the skin of the body surface where the flat surface of the positioning portion is fixed, and wherein the flat contact surface of the fixing portion is continuous with the depressing surface of the fixing portion and is fixed to the body surface by rotating the fixing portion toward the body surface side from the position where the flat contact surface of the fixing portion is approximately orthogonal to the flat surface of the positioning portion.

3. The puncture device according to claim 2, wherein the fixing portion and the positioning portion are each formed by approximately a rectangular plate body, and further comprising an interlink portion provided at one short side of the fixing portion and connected to a lower portion of a side surface of the positioning portion through a hinge portion, a side surface of the interlink portion of the fixing portion constituting the depressing surface.

4. The puncture device according to claim 2, wherein the flat contact surface of the fixing portion is approximately orthogonal to the depressing surface of the fixing portion.

5. The puncture device according to claim 2, wherein the opening window opens through the depressing surface.

6. The puncture device according to claim 1, wherein the flat contact surface of the fixing portion and the flat surface of the positioning portion which are to be fixed on the body surface each include an adhesion member for fixing the flat contact surface of the fixing portion and the flat surface of the positioning portion on the body surface.
