Abstract
Means for exhausting the fumes arising from material being mixed in a mixing bowl, the fumes being drawn off and passed through a filter that removes the noxious materials and returns the air to the room in which the bowl is located. The device is particularly adapted for use in surgical operating rooms where the utmost precautions must be taken to prevent the inhalation of any fumes by the patient and where sterility must be maintained at all times during the operation.
