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. The optical system is configured to provide a field of having a diameter equaling at least 7 mm at a distance of at least 15 mm from a distal opening of said attached tip element. The optical system is further configured to simultaneously provide a distance range of optimal focus having a range of at least 8 mm. The distance range of optimal focus includes a location at a working distance equal to about 30 mm.

Abstract: A hand held ophthalmic examination instrument uses an illumination system that provides amber colored light from a first light source and white light from a second light source to illuminate a target of interest. An imaging system in cooperation with the illumination system captures digital images of the target of interest as illuminated by the light sources.

Abstract: The invention provides a body-worn patch sensor for simultaneously measuring a blood pressure (BP), pulse oximetry (SpO2), and other vital signs and hemodynamic parameters from a patient. The patch sensor features a sensing portion having a flexible housing that is worn entirely on the patient's chest and encloses a battery, wireless transmitter, and all the sensor's sensing and electronic components. It measures electrocardiogram (ECG), impedance plethysmogram (IPG), photoplethysmogram (PPG), and phonocardiogram (PCG) waveforms, and collectively processes these to determine the vital signs and hemodynamic parameters. The sensor that measures PPG waveforms also includes a heating element to increase perfusion of tissue on the chest.

Abstract: An otoscopic instrument includes an instrument housing having a distal end and an opposing proximal end, each end defining a viewing axis of the instrument. A laser light source is disposed in relation to the viewing axis. At least one optical element is configured to direct emitted light from the laser light source toward a target of interest through the distal end of the instrument housing and in which reflected laser light is directed toward the proximal end along the viewing axis. The laser light source can be contained within a releasably attachable laser module to selectively permit separate white light and laser viewing modes of the instrument.

Abstract: An ophthalmoscope device includes a support structure, an image capture device, and a display device. The support structure is configured to be worn by a subject. The image capture device is configured to capture images of the eye fundus of the subject. The display device is configured to overlay images in the field of view of the subject. The overlaid images are used to align the pupil/fovea orientation axis with the optical axis of the image capture device.

Abstract: A system automatically captures a fundus image with limited user interaction such that the fundus image has one or more desired characteristics. The system can retrieve at least one image from an image capture device, process the at least one image digitally to generate a processed image, detect at least one point of interest in the processed image, determine that each of the at least one point of interest is representative of a corresponding feature of the eye, and obtain a fundus image of the eye based on the at least one image.

Abstract: An example eye fundus imaging apparatus can include: a display device; an image capture device configured to capture at least one image of a fundus of an eye; and a control module programmed to: display a target, the target indicating a desired position for the image capture device to capture the at least one image of the fundus of the eye; monitor a relative position of the eye with respect to the target; and when the relative position of the eye corresponds to the target, automatically capture the at least one image of the fundus of the eye.

Abstract: A medical diagnostic instrument or a plurality of disparate medical diagnostic instruments are configured with a common optical architecture that functionally creates a virtual eye to create closer proximity to a patient and therefore increase the field of view in regard to a target of interest. The optical system includes a distal optical element, at least one relay lens and an eyepiece lens in which the optical system can be integrated within at least one instrument or be provided using a releasable module. Additionally, at least one of a viewing assembly and illumination assembly of at least one medical diagnostic instrument can be assembled using a series of components that are connected by interlocking features.
