Abstract
A puncture device which can stick a puncture needle certainly to a predetermined region of a skin includes a puncture needle having a curvature portion, a retaining member retaining the puncture needle, an indwelling device adapted to be indwelled in a living body by way of the puncture needle, and a guide member mounted at a predetermined position of a body surface. The puncture needle is adapted to be stuck into the skin along the guide member.
Claims13
In a puncture device puncturing a skin by a puncture needle, the puncture device comprising:
- a device main body having a contact surface which contacts said skin;
- a puncture needle having a curvature portion of a predetermined curvature radius;
- and
- a puncture needle moving means provided in said device main body for moving said puncture needle along a circular trajectory which said curvature radius draws so as to puncture said skin.
In a puncture device puncturing a skin by a puncture needle, the puncture device comprising:
- a puncture needle having a curvature portion;
- a retaining member retaining the puncture needle;
- an indwelling device indwelled in a living body by said puncture needle;
- and
- a guide member mounted at a predetermined position of a body surface,
- wherein said puncture needle is to be stuck to said skin along said guide member.
In a puncture device puncturing a skin by a puncture needle, the puncture device comprising:
- a hollow puncture needle having a curvature portion;
- a retaining member retaining this puncture needle;
- an indwelling device indwelled in a living body by said puncture needle;
- a fixing member for fixing said indwelling device;
- and
- a guide member mounted at a predetermined position of the body surface, wherein
- said puncture needle punctures said skin along said guide member.
In a puncture device puncturing a skin by a puncture needle, the puncture device comprising:
- a puncture needle having a curvature portion;
- a retaining member retaining this puncture needle;
- and
- a guide member mounted at a predetermined position of a body surface, wherein
- said puncture needle punctures said skin along said guide member.
In a puncture method puncturing a skin by a puncture needle, the puncture method using:
- a device main body having a contact surface which contacts said skin;
- a puncture needle having a curvature portion of a predetermined curvature radius;
- and
- a puncture needle moving means provided in said device main body, comprising said puncture needle is made by said puncture needle moving means to move along a circular trajectory which said curvature radius draws so as to puncture said skin.
