Breast rheid model applied to mammary gland impedance scanning detection technique training and preparation

Abstract

The invention discloses a breast rheid model applied to mammary gland impedance scanning detection technique training, and a preparation method of the model. The model mainly consists of a conductive rubber film layer, sepharose gel and an electrolyte solution, wherein the sepharose gel and the electrolyte solution are wrapped by the conductive rubber film layer in a sealed manner so as to form an overall hemispherical breast rheid model. The model is capable of vividly simulating form and impedance distribution state of a breast and has the characteristics of high form simulation degree, approximation to real impedance parameters, simplicity in preparation process and the like, different model phantoms can be prepared according to structural types and lesion types of the breast, and meanwhile the model can be repeatedly used for a long time and is beneficial for long-term operation training.

Description

technical field [0001] The invention relates to the technical field of bioelectrical impedance detection, in particular to a simulated breast software model and a preparation method for clinical demonstration and technical training of mammary gland electrical impedance scanning detection. Background technique [0002] Breast electrical impedance scanning detection technology is a new functional imaging detection technology for early detection and screening of breast cancer. The detection principle of this technology is: based on the biophysical characteristics of the significant difference between the electrical impedance characteristics of breast cancer tissue and normal tissue, under the condition of applying a safe low-voltage alternating electric field to the breast, a flat array electrode is applied to the breast. The current detection is performed on the surface. By extracting the current difference between each unit, combined with the demodulation of electrical impeda...

Problems solved by technology

At present, operators generally use female human body as the training experiment object in the training of operation skills. The disadvantages of this kind of demonstration training are: (1) Due to the limitation of the experimental objects, the training is often delayed because no suitable volunteers can be found. , or cannot have an intuitive understanding of the imaging results of the lesion because a suitable typical case cannot be found for a while; (2) Due to th
