  • Temporary isolation systems are also known. These are used for temporarily converting a patients' room into an isolation room. This may bring the advantage that it is not necessary to only depend on the special isolation rooms in the hospitals, which are often scarce and may not be equipped with the desired appliances.
  • An inflatable lock for instance, which, basically, creates a lock, is connected to an entrance of a space to be isolated, so that this is converted from patients' room to an isolation room.
