Optoelectronic device for the detection of uterine cervical cancer, comprising a self-positioning attachment

摘要

The present invention relates to a portable device which analyzes cervical tissue using two simultaneous measurements, namely an electrical measurement and an optical measurement. The aforementioned device examines different areas of cervical tissue, taking electrical measurements from same in different frequency ranges and optical measurements in three different wavelengths. Once the measurements have been obtained, they are processed by a configurable device or microcontroller in accordance with mathematical formulae obtained from multiple measurements taken from healthy and cancerous tissues. Three possible responses can be obtained from the processing of the measurements: healthy tissue, cancerous tissue or the presence of human papilloma virus. The inventive device can be used as a self-detection device since it is equipped with an attachment for positioning same upon detection of proximity to the cervix in order to take a correct measurement. The aforementioned attachment also comprises an accessory which can be used to perform the alternative method in which a cell sample is taken and sent for laboratory analysis in order to obtain an immediate response, which can be used by the user or by another person. The purpose of the invention is to provide a minimally-invasive diagnostic device for Papanicolaou testing and to offer an alternative method to the examination that requires the taking of a cell sample.
