Remote medical examination
A platform, tips, and otoscope systems are described herein that can aid with evaluation of human ears (specifically children's ears), diagnose middle ear disease, and suggest appropriate treatments. The platform can serve as an end-to-end evaluation, treatment, and delivery of treatment to a user without requiring an office visit, and improves the accuracy of such systems and ease-of-use.
1 . An otoscope tip that is mountable onto an otoscope, the otoscope tip comprising:
a distal end configured to receive an otoscope;
a substantially conical portion that narrows as it extends from the distal end; and
a cylindrical portion extending from the substantially conical portion to a proximal end,
wherein the otoscope tip comprises an optical pathway extending through the substantially conical portion and the cylindrical portion,
wherein an anterior angle formed between the substantially conical portion and the cylindrical portion is between about 146 and about 148 degrees, and
wherein an interior angle of the optical pathway between the substantially conical portion and the cylindrical portion is between about 165 and about 170 degrees.
2 . The otoscope tip of claim 1 , further comprising: a coating applied to the otoscope tip, the coating configured to dissolve cerumen.
3 . The otoscope tip of claim 1 , wherein the otoscope tip is configured for use in both ears.
4 . The otoscope tip of claim 1 , wherein the otoscope tip is configured for use in one of the left ear and the right ear.
5 . The otoscope tip of claim 1 , wherein the anterior angle formed between the substantially conical portion and the cylindrical portion is configured to accommodate a mean angle of an anterior ear canal and a mean angle of an inferior ear canal.
6 . The otoscope tip of claim 1 , wherein the otoscope tip is configured to suspend the otoscope in an ear canal.
7 . The otoscope tip of claim 1 , wherein a length between the distal end and the proximal end is 1.59 mm.
8 . The otoscope tip of claim 7 , wherein a diameter of the distal end is 0.956 mm and a diameter of the proximal end is 0.165 mm.
9 . The otoscope tip of claim 8 , wherein the anterior angle is 148 degrees, and wherein the interior angle is 165 degrees.
10 . An automated method for at-home imaging of the ear canal and diagnosis of middle ear, the method comprising:
attaching an otoscope tip to an otoscope, the otoscope tip comprising:
a distal end configured to receive an otoscope;
a substantially conical portion that narrows as it extends from the distal end; and
a cylindrical portion extending from the substantially conical portion to a proximal end,
wherein the otoscope tip comprises an optical pathway extending through the substantially conical portion and the cylindrical portion,
wherein an anterior angle formed between the substantially conical portion and the cylindrical portion is between about 146 and about 148 degrees, and
wherein an interior angle of the optical pathway between the substantially conical portion and the cylindrical portion is between about 165 and about 170 degrees;
guiding the otoscope into the ear canal;
illuminating the ear canal with a light source at least through the optical pathway at the otoscope tip; and
obtaining images of the ear canal via the otoscope.
11 . The method of claim 10 , further comprising:
providing a web-based application configured to:
receive the downward-facing images from the camera,
autonomously capture the downward-facing images depicting at least a portion of a tympanic membrane, and
autonomously classify the at least portion of the tympanic membrane from the captured downward-facing images to indicate the status of the middle ear.
12 . The method of claim 11 , wherein the web-based application is configured to provide an output indicative of a normal ear, middle ear fluid (“otitis media with effusion”), or middle ear infection (“acute otitis media”).
13 . The method of claim 11 , wherein the web-based application comprises a machine learning software component that has been trained with images of the same resolution as the camera.
14 . The method of claim 13 , wherein the software has been trained with images that include a rim of an at-home otoscope tip.
15 . The method of claim 13 , wherein the software has been trained with images taken at a variety of angles and orientations.
16 . The method of claim 11 , wherein the web-based application is further configured to present a medical history questionnaire and receive answers to the medical history questionnaire pertaining to the status of the middle ear.
