Abstract

An administration instrument includes an injection button which can be pressed at an angle that is not parallel to a needle with respect to a direction in which the needle is inserted into skin. As a result, it is possible to prevent a force of pressing the injection button from being transmitted in the direction in which the needle is inserted into the skin deeper than initial insertion of the needle, thereby achieving an administration under a stable state.

First claim

1 - 7 . (canceled)

8 . An administration instrument for medical use comprising:
an administration instrument body, a drug solution cartridge detachably housed within the administration instrument body and for separately storing a plural of drug solutions, or a drug and a drug solution, a sliding piece for holding the drug solution cartridge at an end of the sliding piece, an eject lever having an end projecting from the sliding piece and being freely movable in a direction parallel to a needle attachment direction on the sliding piece, and an injection button-integrated driving lever engaged with an engagement portion of the eject lever that is opposite to the end of the eject lever so that the injection button-integrated driving lever is not freely moved, wherein the administration instrument is configured so that, when an needle is attached to the drug solution cartridge, the eject lever is moved so that the end of the eject lever engages with the injection button-integrated driving lever, and thereby the injection button-integrated driving lever is able to freely move and the injection button is able to pressed.

9 . The administration instrument for medical use according to claim 8 , wherein the needle is covered by a cap so that the needle is not exposed.

10 . The administration instrument for medical use according to claim 8 , further comprising a retractable lid for covering the drug solution cartridge.

11 . The administration instrument for medical use according to claim 8 , wherein the administration instrument is configured so that,
when the end of the eject lever projects beyond the end of the sliding piece toward the needle, an eject knob passes through a slit on the sliding piece and a slit on the eject lever so that the drug solution cartridge is not moved, thereby the drug solution cartridge is not able to house within the administration instrument body, and when the needle is attached to the drug solution cartridge, the slit of the eject lever is moved so that the eject knob is pushed down, thereby the drug solution cartridge is able to house within the administration instrument body.
