Abstract
The present invention relates to a portable device which analyses 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.

9. A method of controlling a portable device for performing measurements and calculating the condition of a tissue, characterized by outputting a current to the tissue, measuring the voltage through the tissue, calculating the impedance and saving the result;
- emitting different wavelength lights using LEDs, measuring tissue luminescence and saving the result;
calculating the condition of the tissue based on mathematical formulae, and lighting up a LED depending on the generated result;
the readings from the measurements are compared to mathematical formulae programmed in the device in real time;
said mathematical formulae consider the impedance and luminance which are normally obtained from the taken measurements;
the obtained value is compared in the central processing unit and is classified as normal (green LED) or abnormal (yellow or red LED);
in the case of the optical measurement, three different wavelengths are output and the luminance with which each of them returns is received;
because the size of the test tube is so reduced the transmission is done throughout the whole test tube by means of fiber optics, these fibers being connected to the three LEDs for outputting the signal, whereas for performing the reading there is a photodiode also connected to the fiber optics, then the signal is digitalized and the comparison is made, thus subsequently sending the signal whether normal or abnormal for displaying the final result to the user by means of LEDs.
- emitting different wavelength lights using LEDs, measuring tissue luminescence and saving the result;
