<P>PROBLEM TO BE SOLVED: To provide an administration instrument for medical use which can inject a medical solution securely and with high reliability, prevent an injection button inserted into the skin from inserting deeply in the insertion direction with a pushing force against an injection button when administering, stably administer without wobbling the injection needle, and alleviating physical and mental pain of a patient to be administered. <P>SOLUTION: The administration instrument is structured in such a way that a drug cartridge (52) is loaded through a door which opens and closes at an angle uneven with the injection needle (4) and that the injection button (3) is pushed at an angle not in parallel with the injection needle (4), thereby preventing the injection needle from stinging the skin more deeply than the first depth to which the injection needle is stung with the pushing force against the injection button and enabling stable administration. <P>COPYRIGHT: (C)2013,JPO&INPIT |
