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. In a puncture device puncturing a skin by a puncture needle, a puncture device comprising a puncture needle moving means for retaining said puncture needle to be movable and a skin deforming means for deforming a skin, wherein the puncture needle is moved by said puncture needle moving means and the skin deformed by said skin deforming means is to be punctured.

2. The puncture device according to claim 1 wherein said puncture device includes a fixing portion having a plane fixed to the skin and a skin fixing plane equipped in said skin deforming means, and said skin deforming means deforms the skin so as to form a step portion between said skin fixing plane and the plane of said fixing portion.

3. The puncture device according to claim 2, wherein said puncture needle moving means moves said puncture needle approximately in parallel with said skin fixing plane so as to puncture said step portion.

4. The puncture device according to claim 2, wherein said puncture needle moving means moves said puncture needle approximately in parallel with the plane of said fixing portion so as to puncture said step portion.

5. An administration device comprising:

a puncture device having one puncture needle puncturing a skin and making said puncture needle to go into in parallel with respect to a predetermined layer of said skin; and

an injection device which is in communication with said puncture needle and at the same time injects a substance to a predetermined layer of said skin through said puncture needle, wherein

said substance is administered to a dermis within said skin layers in a range of 0.1 psi to 500 psi with respect to pressure.

6. The administration device according to claim 5, wherein said substance is administered for a predetermined time when said substance is administered with administration flow velocity by 100 μ

l/minute.

7. The administration device according to claim 5, wherein said substance is administered by administration flow velocity 1000 to 2000 μ

l/minute when the pressure is in a range of 90 psi to 500 psi.

8. The administration device according to claim 5, wherein the administration time is 130 seconds or less when said substance is administered with administration flow velocity by 1000 μ

l/minute.

9. The administration device according to claim 5, wherein the administration time is 90 seconds or less when said substance is administered with administration flow velocity by 2000 μ

l/minute.

10. The administration device according to claim 5, wherein the maximum pressure of said substance is 200 psi to 500 psi when the administration flow velocity is made to be 1000 μ

l to 2000 μ

l/minute.

11. The administration device according to claim 5, wherein said substance is administered for a predetermined time in a state in which the maximum pressure of said substance is 460 psi.

12. The administration device according to claim 11, wherein said predetermined time is 90 seconds or less.

13. The administration device according to claim 5 wherein said puncture device comprises a puncture needle moving means for retaining said puncture needle to be movable and a skin deforming means for deforming said skin, wherein said puncture needle is moved by said puncture needle moving means so as to puncture said skin deformed by said skin deforming means.

14. The administration device according to claim 5, wherein said puncture device makes said puncture needle to go into the skin at least by 0.5 mm.

15. An administration device comprising:

a puncture device having one puncture needle puncturing a skin and making said puncture needle to go into the skin at least by 0.5 mm; and

an injection device which is made to be in communication with said puncture needle and at the same time injects a substance to a predetermined layer of said skin through said puncture needle, wherein the maximum pressure of the substance is 200 psi to 500 psi when the administration flow velocity is made to be 1000 μ

l to 2000 μ

l/minute.

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

a puncture needle moving means for retaining said puncture needle to be movable; and

a skin deforming means for deforming said skin, wherein

the puncture needle is moved by said puncture needle moving means so as to puncture the skin deformed by said skin deforming means.

17. The puncturing method according to claim 16, wherein the skin is deformed by said skin deforming means such that a step portion is to be formed between a skin fixing plane and a plane of a fixing portion provided in said puncture device.

18. The puncturing method according to claim 17, wherein said puncture needle is moved by said puncture needle moving means approximately in parallel with said skin fixing plane so as to puncture said step portion.

19. The puncturing method according to claim 17, wherein said puncture needle is moved by said puncture needle moving means approximately in parallel with the plane of said fixing portion so as to puncture said step portion.
