Abstract: A method and apparatus are provided for measuring hemostasis. The apparatus includes a torque sensing column having a torque sensing element and a drive ring disposed around a body of the column and in registration with the column so as to allow rotation of the drive ring around a longitudinal axis of the column. The apparatus further includes a first guide shaft rigidly secured to the drive ring, the guide shaft extending parallel to the longitudinal axis of the column and a cup holder movably attached to the guide shaft, allowing the cup holder to move parallel to the longitudinal axis of the column. The apparatus also includes a sample cup adapted to engage the cup holder on a outer surface and the torque sensing element of the torque sensing column on an inner surface.

Abstract: An improved ear probe tip for the end of a probe which can be inserted into an ear canal. The ear probe tip comprises a body portion having an inner surface, an outer surface, a first end and a second end. The body portion inner surface defines a passage that extends the entire length of the body portion. The ear probe tip also has a plurality of flexible annular flanges disposed at spaced intervals on the outer surface of the body portion.

Abstract: A novel quick connect electrode headbox is provided with an internal assembly positioned within a housing. The internal assembly has at least one support and a plurality of pivotable electrode receptacle bases pivotably mounted to the at least one support. Further, the plurality of pivotable electrode receptacle bases have a plurality of receptacles each adapted to receive an electrode connector.

Abstract: An apparatus for performing manipulation and analysis of data characteristic of brain electrical activity of a patient. Computer analysis is utilized to provide the most useful form of topographical maps and related data for evaluation of a patient by a user. The application can be operated as part of an integral unit or remote from the location where brain electrical activity signals are measured on the patient.Threshold circuitry ensures that only signals meeting predetermined conditions are stored. A user modifiable digital filter allows for on-line analysis of changes in filter characteristics. A simultaneaous display of a plurality of topographical maps in visual summary format is presented. Readability is enhanced by showing only the color codes that actually appear in the topographical map. Montages can be created.

Abstract: An apparatus for monitoring and operating on brain input activity signals to provide topographical maps characteristic of patient brain activity. The apparatus senses the brain input activity signals and processes the signals to provide detailed information on patient brain activity. Complete topographical maps of the patient brain are activity constructed by a line-by-line interpolation method. A color coded scale adjacent the topographical map is utilized to provide additional information on patient brain activity. The user has a number of options available to select various information for display and analysis.
