Background

An elevator is an essential infrastructure in modern life, and is used for providing rapid and convenient personnel and material transportation in high-rise buildings such as buildings. According to the form of an elevator, the elevator is mainly divided into a step elevator and a box elevator. The latter has the characteristics of higher conveying speed and safety due to the adoption of vertical lifting, closed car, small occupied space and the like, so that the application is wider.

Based on van elevator possesses can arrive appointed floor fast, friendly to the handicapped person, high advantage such as the risk of weighing down is low. At present, the elevators in hospitals are mainly box elevators. However, the flow of people in hospitals is often huge, and the elevator users have more patients, and in addition, the current van elevator generally only carries out simple ventilation circulation and has no bacteriostatic and disinfectant functions. This causes the van elevator in hospitals to become a high-risk area for cross infection of various respiratory diseases (such as influenza virus). Therefore, it is urgently needed to provide a medical elevator with disinfection and sterilization functions.
