The present invention relates to a self-disinfectable portable stick capable of performing a touch function on behalf of a user's hand.

The content described in this section merely provides background information on an embodiment of the present invention and does not constitute the prior art.

Recently, as viral infections such as the highly contagious Middle East Respiratory Syndrome (MERS), SARS, and Corona-19 have occurred, people are taking precautions from the penetration of droplets of infected people into the respiratory tract or the mucous membranes of the eyes, nose, and mouth to prevent virus infection. In order to prevent this, masks such as static masks (KF94) and dental masks are worn, and hands and belongings are frequently disinfected using disinfectants.

In order to prevent infectious diseases caused by these bacteria and viruses, it is important to wash your hands thoroughly. Because the virus can also be present in door knobs and public phones that we inadvertently touch, it is recommended to wash your hands frequently while going out and avoid touching your eyes, nose, and mouth with your hands as much as possible.

In particular, in a living space shared with several people, there are frequent cases where you have to press the button with your finger, such as a button-type door lock, an elevator button, an intercom button, etc. When there are bacteria or viruses in a certain button, the button is pressed. Infection can occur through the hand that was pressed, and through direct contact or respiratory transmission through this, the problem of human-to-human infection can occur. According to a study by the National Institutes of Health in the United States, it was confirmed that the coronavirus survives for 24 hours on paper board, 2-3 days on plastic and stainless steel, and more than 4 hours on copper surface.
