The prototype of this scheme is inspired by conch, which has a hard shell in people's impression, giving people a sense of security to be protected. Conch shape is round and lovely, in the case of epidemic tension and heavy responsibility, to bring some psychological comfort. In addition, the shape of conch can be divided into multiple cabins to meet the requirements of simultaneous isolation and treatment of multiple people, which to a certain extent improves the efficiency of transporting infected people and relieves the pressure of medical staff.
