Abstract: An otoscope apparatus having an objective lens configured to focus light from an object, a field lens positioned parallel to the objective lens along an optical axis, a first aperture and a second aperture positioned, respectively, at a distal end and a proximal end of the objective lens, and a third aperture positioned at a distal end of the field lens. The otoscope apparatus is adapted to be releasably attached to a camera of a smart device. The otoscope apparatus may capture a picture or video of the outer ear, the middle ear, and/or the ear canal of a patient utilizing the camera of the smart device. Such a picture or video of the outer ear, the middle ear, and/or the ear canal may be sent to a remote healthcare professional for diagnosis of an ear infection.

Abstract: A smart device may assist a user in aligning an otoscope of an otoscope clip device with a camera of the smart device. A model identification may be determined. The model identification may indicate a model associated with the smart device. An alignment image may be determined using the model identification. The alignment image may be displayed on the display of the smart device.

Abstract: A device for attaching an optical element, such as an otoscope, to a smart phone for diagnosing and/or identifying problems of an outer ear, a middle ear, and/or an ear canal of a patient. The device may comprise a main body. The main body may comprise an aperture and a first engagement member configured to engage with a second engagement structure that belongs to the optical element. A first surface may be connected to the main body and configured may be to contact a first smart phone surface. A piston may be provided that may comprises a second surface that may be parallel to the first surface and may be configured to contact a second smart phone surface. A threaded knob may be provided and may be connected to the piston through the aperture.
