The present invention is a detachable member having a magnetic force, and stores the emergency medicine in a storage room provided to be sealed with the outside through the cover part on the main body, and carry it on the patient's own wrist through the holder part to quickly respond to an emergency situation. It is about the technology that has been made possible. The present invention as described above is provided with a material of a non-magnetic material, a removable cover portion and a body portion； A portable emergency medicine storage device that is worn on a wrist through a holder part fastened to the main body, comprising: a storage room for storing the emergency medicine by being concave in a central part of the body of the main body； A concave groove formed in the shape of a lung along the upper outer portion of the storage chamber； A compression pad in the form of a lung path that is press-fit to form an exposed portion from the body surface in the groove, and compresses the exposed portion by external pressure； It is formed in two or more dispersively on the outer portion of the compression pad, and includes a mounting groove inserted and installed so that a detachable member having a magnetic force is depressed from the body surface, and the body of the cover portion facing the body portion is compressed in correspondence with the groove A concave groove in the form of a lung path for guiding the exposed portion of the pad to be inserted into close contact； The outer portion of the groove includes a mounting groove in which a detachable member having a magnetic force is inserted and installed so that a protruding portion is formed from the body surface in correspondence with the mounting groove, and the body portion and the cover portion are adjacent to each other by suction force between the detachable member corresponding to each other. When it is finished, the thickness before compression with respect to the exposed portion inserted into the groove
