It has been found that since 1980, electric fields have become popular in biological and medical fields, including killing of microorganisms, cell fusion, gene transformation, and tumor therapy. YoramPati et al discovered in 2004 that alternating AC electric fields with low electric field strength of 1V/cm-2V/cm and medium and low frequency (100-300 KHZ) can selectively inhibit tumor cell proliferation. With the research on the action mechanism of tumor treatment electric fields (TTF), TTF has many potential advantages as a new tumor treatment method compared with conventional surgery and radiotherapy and chemotherapy.
At present, the mechanism of action of TTF is primarily to interfere with mitosis, which destroys cancer cells. If an uneven external electric field is applied in the mitosis process of the cancer cells, microtubules consisting of polar molecules are subjected to reversal polarization in the early mitosis stage and move along the direction of stronger field intensity, so that the microtubules cannot be gathered into spindle threads, and the mitosis of the cancer cells is stopped; meanwhile, when the direction of the applied external electric field force line is parallel to the long axis of the dividing cell, the density of the electric field force line and cytoplasm at the narrow mitotic groove of the cell at the end stage of mitosis is highest, and under the action of coulomb force, the cell membrane at the mitotic groove is cracked and cannot divide two complete new cancer cells.
At present, a TTF technology-based tumor therapy apparatus mainly acts on a human body by means of at least one set of electrode patch pairs, the electrode patch pairs are oppositely arranged on a target biological tissue, and a target therapy electric field is generated between the electrode patch pairs by applying an alternating voltage to the electrode patches. In TTF treatment, the contact part of the electrode patch and the skin can be heated along with the enhancement of the field intensity, and the human body can be injured due to overhigh temperature, so that the detection of the temperature of the target biological tissue acted by the electrode patch is very important. The existing electrode patch is provided with a temperature sensor for detecting the temperature of the electrode patch acting on the surface of a human body.
However, it was found that during the operation of TTF, the data fluctuation monitored by the temperature sensor on the electrode patch is a bit large, and the specific data information is shown in table one.
Table one:
according to the information shown in table one, the existing electric field generating device collects temperature information during operation, and does not have the second time period t2 when the electric field at the target biological tissue is 0. The fluctuation of the Temperature value corresponding to the Temperature information acquired by the four NTC (negative Temperature Coefficient sensor) Temperature sensors is large, so that the Temperature acquired by the Temperature sensors is not accurate, the Temperature information acquired by the electric field generating device is not accurate, and the treatment effect of the electric field generating device is required.
