Desarrollo de una cámara de secado para optimizar el mantenimiento de endoscopios en la empresa Perfectech

Abstract

The objective of this project is to design and implement a drying chamber to optimize the maintenance of endoscopes in the company Perfectech located in Guayaquil, Ecuador, so as to ensure an efficient and controlled process. Endoscopes are specialized medical equipment for minimally invasive procedures, used for diagnostic, therapeutic and surgical procedures inside the human body. By means of natural orifices, doctors use endoscopy to treat diseases affecting the stomach, esophagus, etc. It is of utmost importance for this branch of medicine that the equipment is in optimal conditions when it enters into repair for several reasons: free of microorganisms to avoid cross contamination, free of leaks, etc. The chamber is designed to eliminate moisture in the internal channels and for the drying of the epoxy glue in the distal tip, addressing critical points such as the insertion tube and the epoxy ring, common areas of wear that cause leakage and moisture in the endoscope chamber. The system consists of an ESP32 as the main microcontroller, temperature and humidity sensors, and an HMI display, as well as a closed-loop controller (PID) to regulate the thermal resistances. This configuration allows real-time monitoring of the drying conditions. The results show a significant improvement in the efficiency and quality of the process, surpassing the traditional manual method, such as drying under an incandescent lamp. In conclusion, the drying chamber represents an efficient and safe solution for the maintenance of endoscopes, contributing to process optimization at Perfectech.
