How to connect a USB flash drive to a hospital computer?

Computers in the hospital intranet can't be plugged into USB flash drives. Because the hospital's intranet stores patients' personal privacy and inpatient disease information, it is easy to transfer the virus from the external network to the internal network by using U disk, which leads to the data insecurity in the internal network. Now all localities and industries have different regulations on the trial of USB flash drives. Please follow the regulations of the hospital.
