Description

The present invention relates to an automatic seat disinfection device.

Currently, the outbreak of a highly contagious novel coronavirus (formally called "SARS-CoV-2") has caused a global pandemic, and measures to prevent infection are urgently needed. The common points of outbreaks are "poor ventilation", "spaces where people gather closely", and "places where an unspecified number of people are likely to come into contact". Infection is likely to occur.

The droplets from the patient directly adhere to the medical instruments and sheets around the patient, fall and adhere to them, or indirectly adhere to them. Therefore, not only hospital personnel, but also droplets attached to medical instruments and sheets become routes of infection to other patients. This makes it important to disinfect everything to prevent infection.
