US Patent:

6875196, Apr 5, 2005

Filed:

Feb 16, 2001

Appl. No.:

10/203850

Inventors:

Joseph L. Abita - Boyds MD, US
Leonard R. Proctor - Baltimore MD, US

Assignee:

The Johns Hopkins University - Baltimore MD

International Classification:

A61M031/00

US Classification:

604 67, 604 66, 6048901

Abstract:

The present invention provides automated control of aural irrigation by utilizing a process controller in connection with an irrigation supply unit and irrigation delivery unit. Sensors situated in the irrigation supply unit and irrigation delivery unit provide data feedback to the process controller enabling essentially instantaneous and precise control of operational parameters. In addition, data customized to individual patients as well as historical data for use in analysis is stored in and processed by the control processor to increase the accuracy and utility of the aural irrigation system. Further, patient response data (e. g. , from an ENG sensor) is also input to the process controller, thereby enabling extremely fast and accurate test analysis with minimal effort by the device operator.

Abstract:

A caloric testing technique and apparatus for evaluating vestibular ear disorders by independently stimulating the left and right lateral canal receptor organs, using heated and cold air, and measuring the responses in order to obtain an indication of disordered vestibular function. Timed irrigation periods are employed, the periods being adjustable so as to control the magnitudes of the caloric stimulations, and the measurements of responses are made by the electrical recording of eye movements for accurate measurement of nystagmic response intensity.
