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 device designed for the attachment of a movable optical element to a smart device may be provided. The device may comprise a main body. The main body may comprise a first member attached to a second member and a third member. An inset angle may be formed between the second and third members. The third member may comprise an aperture. The second member may comprise a first contact surface that may be configured to make contact with a first surface of a smart device. A threaded knob may be connected to a piston through the aperture. The threaded knob may be arranged or configured to move the piston in a direction relative to the first surface when it is turned.

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.
