Claim Text:
1. A portable device for self-diagnosis test of cervical cancer tissue, the portable device comprising: a test tube comprising, in a proximal tip, electrodes to transmit electrical current to the tissue and receive a tissue electrical voltage produced by the applied electric current, a plurality of emitting optical fibers to transmit light pulses to the tissue, and a plurality of receiving optical fibers to pick up the light intensity of the tissue produced by the light pulse; a distal housing and the test tube forming a single body, the distal housing including operational amplifiers to generate and regulate the electrical current transmitted to the tissue through the electrodes of the test tube, inner LEDs to generate the light pulse transmitted to the tissue through the emitting optical fibers of the test tube, photodiodes to sense the light intensity of tissue from the receiving optical fibers of the test tube, and a microcontroller operatively connected to the operational amplifiers, to the inner LEDs, to the photodiodes, and to the electrodes; and a plurality of outer LEDs connected to the microprocessor, wherein the plurality of outer LEDs are positioned on a surface of the distal housing to present a signal such that the signal presented by the outer LEDs is visible to a user performing the self-diagnosis test of cervical cancer tissue using the portable device; wherein the microcontroller receives the electrical voltage and light intensity of the tissue through the electrodes and photodiodes respectively to determine the impedance and light intensity values of the tissue, compares the impedance and light intensity values of the tissue to stored and preset tissue impedance and light intensity values, and triggers the outer LEDs to present the signal indicative of a test result.
