Photoscope: vídeo-otoscópio de baixo custo a partir de impressão 3D e visualização via smartphone

Abstract

Otoscopy is a common medical imaging exam in the screening of outpatients who are under the specialized care of an otolaryngologist. Because it involves the upper airways, it is seen as a possible risky procedure for health professionals positioned in the front lines, as it aggravates exposure to contamination by notifiable diseases, among which COVID-19 stands out today. The availability of the otoscope and specialist for this examination is limited to, which is why basic health care achievements and specialized centers in peripheral countries are sometimes unqualified. Understanding these aspects, the objective of this study is to present a safe and low-cost device that allows the performance of otoscopies, ensuring significant doctor-patient distance during its use and contributing to the early diagnosis of mortgages involving the hearing system that require surgical ruptures. By consulting the database, patent repository, access to prototyping technology (3D printing) in addition to the use of free software and a smartphone, it was possible to develop an alternative product that meets proven situations. The main results transcended the initial perspective: it was also observed that the device developed can contribute to post-surgical follow-up, avoiding localized displacements to the otorhinolaryngology office.
