An otoscope that utilizes ambient light is disclosed. The otoscope includes a fiberoptic cable(s), as opposed to batteries, to illuminate the inspection area. The otoscope made of non-metallic and/or non-ferrous materials to permit its safe use in highly flammable oxygen or magnetic environments. The otoscope includes a handle, a head coupled to the handle, and a specula coupled to the head. An eye piece coupled to the head opposite the specula. A reflective lens is positioned within the head. A fiber optic cable is positioned within the handle. The handle includes a first end positioned opposite a second end. The head is coupled to the first end. The fiber optic cable provides light to the reflective lens. The fiber optic cable extends from the front end to the second end. The reflective lens is oriented to reflect light to the specula.

An apparatus comprises a shaft, an expandable dilator, and at least one ventilation pathway. The shaft defines a longitudinal axis and comprises a distal and proximal ends with at least one shaft lumen. The expandable dilator comprises body with its own proximal and distal ends. The body is configured to transition between a contracted state and an expanded state. The body is configured to dilate a Eustachian tube of a patient in the expanded state. The at least one ventilation pathway is configured to provide ventilation from the distal end of the body to the proximal end of the body when the body is in the expanded state. In some examples, the ventilation pathway comprises a set of transversely oriented vent openings formed through the shaft. In some other examples, the ventilation pathway comprises a space defined between one or more radially outwardly protruding features of the expandable dilator.

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.

An apparatus for performing a medical examination is disclosed. The apparatus includes a mounting interface configured to couple to a smartphone including a camera and illuminator. A depressor blade has a proximal end demountably attachable to the mounting interface and configured to displace a patient's tongue to provide access for illumination of a patient's pharynx by the illuminator, thus facilitating capture of an image of the pharynx by the camera. An otoscope attachment has a proximal end demountably attachable to the mounting interface, the ostocope attachment terminating in a speculum shaped for insertion into a patient's ear. One or more optical elements are disposed on the ostocope attachment and are configured to direct illumination provided by the illuminator into the patient's ear, thus facilitating capture of an image of the patient's ear by the camera.
