Calorimetric aural nystagmus test - by inserting inflatable container into external duct, expelling air by inflation and transferring heat between duct wall and container

摘要

Calorimetric aural nystagmus test is carried out by introducing a flexible container into the external audible duct, introducing a fluid medium into the container to inflate it and expel the air entrapped between the container to inflate it and expel the air entrapped between the container and the duct walls, transferring thermal energy between the fluid and the duct and preventing the egress of the fluid out of the container and direct contact of the fluid with the duct.
