Abstract: An otoscope includes an instrument head, a tip element and an optical system. The instrument head has a distal insertion portion for insertion into an ear of a human or veterinary subject. The distal insertion portion has a distal opening. The tip element is releasably attached to the distal insertion portion. The tip element has a distal opening. The optical system is contained within the instrument head. The optical system includes a plurality of optical components. The optical system further comprises a viewing component for viewing of an image of a target of interest aligned along an optical axis disposed within said distal opening.

Abstract: A digital otoscope for capturing live and still digital images of body tissue and having associated optical characteristics that improve the quality of visual information gathered for medical inspection of both human and veterinary subjects. The digital otoscope includes a tip element having dimensions that are small enough to fit into a small body cavity, such as an ear canal. The tip element and the otoscope enclose an assembly of optical components yielding optical characteristics that provide a substantially wide field of view and a substantially wide range of optimal focus from which to form visual information within a small and confined body cavity.

Abstract: A flexible and disposable allergen-containing patch is provided with markings transferable to the skin. The patch may also include piercing elements to become an all-in-one system. A reusable actuator enables a user with little training or experience to administer multiple test injections with the disposable patch. A scope allows magnified viewing of a test site after the skin test is provided, the scope incorporating the patch as a releasable component. An all-in-one applicator assembly that can be bent to fit a convex engagement surface of a rolling actuator is also provided.

Abstract: An LED for use with a medical diagnostic instrument having an adapter disposed between an instrument head and a hand-grippable handle, the LED being removably attachable in relation to the adapter in order to permit selective replacement of the LED, as needed. The LED is situated in order to provide mechanical and electrical interface with at least one of the adapter and the instrument, thereby enabling the adapter and the LED to convert the illumination source of the instrument selectively between an incandescent light source and the LED. The adapter matches a polarity between the LED and a power supply that is specifically intended for powering an incandescent light source.

Abstract: An apparatus that can measure images of at least a portion of an eye and record data sets indicative of a neurological condition. A method interrelates an image and a data set to provide an interpretive result. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus and method can be used in an iterative measurement process, in which the apparatus attempts to discern normal health from a state of health that is not normal health. If the interpretive result is consistent with normal health, the process terminates, information is recorded, and an optional report is given. If the interpretive result is not consistent with normal health, the apparatus and method attempts to distinguish which condition is consistent with the data and images used, and can iterate with additional measurements and information to attempt to provide a useful interpretive result.

Abstract: An apparatus that measures images of at least a portion of an eye and records data sets indicative of a neurological condition. A method of the invention employs a plurality of images, or a plurality of data sets, or at least one image and at least one data set to provide an interpretive result based on the interrelation of the images and data sets, such as by superposition. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus includes modules that observe images and/or data sets, that analyze the information, and that superpose the information. Modules are provided to store information, to provide data output, to provide reports, and to display information, including superposed images and data. Modules can be provided in hardware, in software, in firmware, or in combinations thereof.

Abstract: The invention includes methods and apparatus for measuring (Intraocular Pressure) IOP and (Corneal Thickness) CT for diagnosis and for monitoring a condition of health of an eye. The apparatus uses measurements selected from at least one of IOP and a CT, and a plurality of IOP measurements to deduce an interpretive result indicative of a condition of an eye. In another embodiment, the apparatus measures a relationship between an applanated area of variable size and a selected one of an applied force and an applied pressure. The relationship is used to deduce an interpretive result indicative of the condition of an eye. The result can be displayed to a practitioner. The practitioner uses the result to determine a course of treatment as necessary, and to monitor the effect of a course of treatment on the state of health of the eye over time.

Abstract: A wall mounted power supply for a remote instrument handle has a novel self compensating voltage regulating circuit that remains in precise calibration despite variable voltage drops in the load, cabling, and control switches. Power output is enabled by an infrared emitter-detector combination disposed in the device's cradle that senses the absence of the instrument handle therein.
