Abstract: A bath chair is adapted to be used with an existing bathtub. The chair includes a stabilizing means for securing the chair to the tub, and water from the chair flows into the tub. A transfer seat is provided for assisting invalids in entering the chair. Improved water flow includes perineal outlets, and a splash plate is provided for other water outlets to force water to cascade down the back of the chair.

Abstract: A microprocessor based instrument designed to retrofit into existing perimeters utilizing the mechanics and stimulus control aspects of the existing perimeter. The device includes an array board positioned adjacent the perimeter mechanical arm and includes a multiplicity of visual indicators spatially arranged in a composite pattern of testing locations required for one or more ophthalmic testing procedures. A processor is connected to the array board for sequentially actuating the visual indicators in accordance with the testing procedure whereby the operator guides a cursor attached to the perimeter mechanical arm to align with the actuated indicators and control the location of the perimeter test stimulus. The processor includes means for sensing the position of the cursor, silently presenting a light flash to the patient, and a memory which records the patient's responses.

Abstract: First and second electro-optical display devices for displaying visual acuity targets, one of which is adapted to be viewed by a patient and the other of which is adapted to be viewed by an examiner. An electronic memory is connected to the display devices containing a plurality of acuity targets stored in various orientations for presentation to the display devices. Controls are provided in an examiner's console for selecting one of a plurality of available target sizes, "zoom" increasing size or decreasing size, selecting a single or a line of multiple target characters, providing normal or reverse video presentation, changing the orientation of the target characters, and providing a blank screen. The size of the targets is varied by changing the dimensions of each of the targets about its own center and in the case of multiple targets, maintaining proportional spacing between the targets as the size of the targets vary.

Abstract: For more easily and comfortably bathing invalids, a chair having a substantially horizontal seat, a semi-cylindrical wall extending upwardly from the seat for closely surrounding the back and sides of the invalid, the upper edge of the semi-cylindrical wall being inclined downwardly and forwardly to the level of the seat and being curled forwardly and inwardly to form a channel with an inturned lip, a spray tube with bottom openings in the channel for directing water downwardly along the back and sides, and the arms and thighs of a seated invalid, a deep well reservoir surrounding the seat and connecting the seat and the semi-cylindrical wall, a shallow foot-pan below and forward of the seat and whose rim is extended upwardly at the rear to join the front of the seat, the forward edge of the rim being well below the level of the seat to permit easy ingress of an invalid, a valve controlled drain passage leading from the deep well reservoir to the foot pan, and means for supplying wash water independently to t

Abstract: A portable eye examination system cart is provided with an instrument console which conveniently supports eye examination devices, an electric power system effective to provide electrical power to the eye examination devices which are electrical, including automatic turn on and off switches when removing and replacing electrical eye examination devices, and a monitor panel. The electrical system may include a rechargeable battery system and recharging circuitry. The cart includes storage areas for convenient location of ophthalmic drugs and examination supplies, small instrument accessories, spare lamps and parts, patient record charts and other miscellaneous items. The cart includes easily manipulated, lockable covers to secure all instruments and supplies from threat of unauthorized use, and the cart is constructed of lightweight material for good maneuverability with dimensions appropriate for convenient use between hospital beds, movement through hospital corridors, and the like.
