PUNCTURE DEVICE AND MEDICAL FLUID ADMINISTRATION DEVICE
First Claim
1. A puncture device comprising:
- a housing unit including an attachment surface configured to be attached to a body surface of a user;
a puncture needle including an outer needle and an inner catheter located in the outer needle, the puncture needle being configured to be projected from the attachment surface to be punctured into a body of the user;
a puncture mechanism configured to project the puncture needle, in which a distal end portion of the inner catheter is located in the outer needle, from the attachment surface to be punctured into the body of the user, and pull back only the outer needle of the puncture needle into the housing unit with the inner catheter of the puncture needle indwelled in the body; and
a puncture angle adjustment mechanism configured to adjust a puncture angle of the puncture needle, which is an angle of the puncture needle with respect to the attachment surface.
