<P>PROBLEM TO BE SOLVED: To provide a puncture-depth (angle)-adjustable portable liquid-drug administration device for adjusting the puncture depth of a catheter in angle in accordance with each one of cases for subcutaneous and intramuscular injection of insulin. <P>SOLUTION: An angle adjustment mechanism adjusts the projection angle of a puncture flow passage needle 304 and a sheath 311 with respect to the bottom surface of a housing part. The puncture angle of the puncture flow passage needle 304 and the sheath 311 with respect to the skin of a user that is set in parallel with the bottom surface is changeable within the range of 20°-90°. Thus, puncture is performed at the arbitrary depth in the living body, and thereby usability for all the users can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
