Abstract
A liquid medicine self-administration device which is capable of administering a liquid medicine to a patient in a single shot and with which the refilling of the liquid medicine can be performed by a one-touch operation. The device includes a casing 1 having two open ends, a port portion 2 closing one of the open ends of the casing, a reservoir 3 attached to the port portion 2 and capable of being easily deformed by pressing and of being restored to its original shape. A pushing means 4 is slidably inserted into the other open end of the casing 1 and is adapted to press and deform the reservoir 3. The pushing means 4 comprises a cylindrical member 41 inserted into the casing 1 so as to be able to slide along the inner wall of the casing 1 and a spring 42 housed within the cylindrical member 41.
