Whole-breast electric impedance examination electrode

Abstract

The invention discloses a whole-breast electric impedance examination electrode. The whole-breast electric impedance examination electrode is characterized by comprising a shell (2) with an arc-shaped cross section, wherein one face, which corresponds to a tested breast, of the shell (2) is provided with an electrode array film (3); the electrode array film comprises an electrode array film substrate (306) and over ten electrode array film electrode points (307); the electrode array film substrate (306) is made of an insulated elastic material; the radian of the electrode array film (3) can be changed according to the surface radium of the tested breast; the electrode array film electrode points (307) are embedded into the electrode array film substrate (306) with the head portions of the electrode array film electrode points (307) being contacted with the surface of the tested breast. By adopting a circular arc-shaped contact surface, the entire breast can be covered by measuring once. Moreover, the magnitude of the pressure of an inflation cabin can be adjusted to deform the contact surface in order to adapt to the examination of breasts of different sizes.

Description

technical field [0001] The invention relates to a mammary gland electrical impedance inspection electrode, in particular to a whole mammary gland electrical impedance inspection electrode conforming to the shape of the mammary gland to be tested. technical background [0002] Electrical impedance testing is a new breast cancer screening technology. The electrical impedance of cancerous tissue is significantly different from that of healthy tissue, and the electrical impedance detection is based on this difference, and the electrical impedance detection is carried out by using the electric field theory. In the implementation of the technology, current needs to pass through the breast tissue to form an excitation-detection circuit. The detection element in contact with the human body is called a detection electrode, and the detection electrode is composed of multiple array points, which are called detection electrode points. The excitation current of the tissue is limited and...

AI Technical Summary

Problems solved by technology

In the implementation of the technology, current needs to pass through the breast tissue to form an excitation-detection circuit. The detection element in contact with the human body is called a detection electrode, and the detection electrode is composed of multiple array points, which are called detection electrode points. The excitation current of the tissue is limited and the signal is weak. In addition, there are differences in breast shape and skin impedance, so the test results are unstable.
