Due to factors such as the risk of hospital infection, disinfection and isolation control, and treatment needs, special wards (such as ICU wards) usually strictly limit the visiting methods and time of patients and their families. In addition, although visiting is a behavioral need between patients and their relatives and friends, the communication, instructions and care needs of medical staff for family members in ICU wards are more prominent. For this reason, by equipping professional video equipment for isolated visits, it can effectively avoid infection, increase visiting time, and shorten the distance between relatives. At the same time, it can assist medical staff in integrating and increasing the communication opportunities and process control of medical staff during the visiting process, effectively improving the operating efficiency of the ward and the satisfaction of patients.
