Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings.
[0032] Studies have shown that biological tissues are composed of a large number of cells, and extracellular fluid exists between cells. A large number of dissociated ions are dissolved in it, so the extracellular fluid has good conductivity. It has been confirmed that the intracellular fluid also has good electrical conductivity, and the concept of an equivalent model was finally proposed by some early scientists. which include such as figure 1 The equivalent circuit model of a single cell in the biological tissue shown. In the figure, Re is the resistance of the extracellular fluid, Ce is the parallel capacitance of the extracellular fluid; Rm is the resistance of the cell membrane, Cm is the parallel capacitance of the cell membrane; Ri is the resistance of the intracellular fluid, and Ci is the parallel capacitance of the intracellular fluid. In the case of low ...

The invention discloses a device for assessing early risks of breast cancer. In the device, an output end of a frequency sweeping sine wave generating circuit is connected with an input end of a voltage / current switching circuit, an output end of the voltage / current switching circuit is connected with an input end of an impedance matching circuit, an output end of the impedance matching circuit is connected with a test electrode array which is placed on a mammary tissue of a person to be tested, an input end of an amplitude processing unit is connected to the output end of the voltage / current switching circuit, an output end of the amplitude processing unit is connected to an input / output (I / O) port of a lower computer, a first power supply is connected with the frequency sweeping sine wave generating circuit, the voltage / current switching circuit, the test electrode array and the lower computer, a second power supply is connected with the amplitude processing unit, control ports of the test electrode array and the frequency sweeping sine wave generating circuit are connected with the I / O port of the lower computer, and the I / O port of the lower computer is connected with an input end of an upper computer to complete data transmission. The device for accessing early risks of breast cancer is convenient for examination, simple in structure and low in cost.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and relates to a biomedical device for predicting and diagnosing the risk of mammary gland tissue lesions. Background technique [0002] Breast cancer is one of the most common malignant tumors in women. According to the statistics of relevant departments, the incidence of breast cancer among women in my country is currently rising sharply at an annual growth rate of 3%-4%. About 180,000 women suffer from breast cancer every year, and more than 13,000 women die of breast cancer. Breast cancer has become a The cancer with the fastest-growing mortality rate since my country's reform and opening up. [0003] So far, some existing medical imaging technologies, including CT, MRI, and ultrasound, have not been able to achieve long-term and continuous detection due to the use of radiation, nuclides, harm to the human body, high price, or difficult operation. Although electrical impedance tomogr...
