High-precision multi-tissue simulation fetal model

Abstract

The invention discloses a high-precision multi-tissue simulation fetal model, and belongs to the field of medical applied researches. The model mainly comprises simulation fetal bones, simulation fetal organs and simulation fetal muscular tissues, wherein the simulation fetal bones are made of hydroxyapatite, the simulation fetal organs are made of elastic materials, the simulation fetal muscular tissues are made of elastic materials, and the model is characterized in that according to computed tomography data of a fetus, the three-dimensional printing technology is adopted to make a fetal high-precision acrylonitrile-butadiene-styrene plastic model, and a simulation fetal silicone mold is made through the model. The manufactured simulation fetal organs and the simulation fetal bones are fixed in the mold, simulation muscular tissue material pouring is carried out, and the manufacturing of the simulation fetal model is completed. The manufactured simulation fetal model provides the characteristics such as ultrasound and X-ray detection of the external fetal simulation shape, the internal organs and the bones, and is widely applied to the fields, such as medical training and teaching, medical image processing and medical equipment detection.

Problems solved by technology

[0004] All of the above methods use the fetal model to test the performance of medical imaging equipment. The problem with them is that only the muscle tissue of the fetus is considered when simulating the fetus, and the organ tissue, bone tissue, etc. of the fetus are not considered.

Therefore, it is difficult to give students a real medical technology experience in medical training teaching; the images obtained by the medical imaging system are different from the images obtained by the real fetus under the medical ultrasound imaging system, such as: the muscle tissue of the real fetus is in medical ultrasound Under the imaging system, the imaging brightness is low and the contrast is low, while the image obtained by the simulated fetal muscle tissue under the medical ultrasound imaging system has high brightness and high contrast.
