Problems solved by technology

At present, in the research of some new cerebral hematoma monitoring technologies, most of the animal models or a single material are used to simulate the brain, but the animal model cannot accurately control the size of the cerebral hematoma, and it is troublesome to make. Using a single material brain model, the experimental results obtained There will be a large error between the result and the actual value

Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] In the present invention, the 3D printing technology can be used to conveniently and quickly produce a model with the same shape and structure as each tissue, but the materials used in 3D printing cannot meet the dielectric properties that can simulate the various tissues of the brain. The tissue part is made into a cavity structure, and the 3D printing is only a frame, and then filled with materials that can simulate the tissues of the brain, so as to not only maintain the complex morphological structure of the tissues of the human brain, but also simulate the dielectric properties of the tissues .

Abstract

The invention relates to a manufacturing method for a multilayer-uneven-structure brain hematoma model, and belongs to the technical field of biomedicine. The manufacturing method includes the following steps that S1, human-body brain data is scanned through nuclear magnetic resonance to obtain three-dimensional structure data of the skull surface, three-dimensional structure data of the grey matter surface and three-dimensional structure data of the white matter surface; S2, the three-dimensional data of the skull, the three-dimensional data of the grey matter and the three-dimensional data of the white matter are led into 3dsmax to be merged, subjected to model detail reducing and shell adding treating; S3, the model is manufactured according to the data obtained in the S2; S4, cavities corresponding to tissue are filled with corresponding simulation materials, namely, materials with the dielectric constant and the electric conductivity equal to corresponding tissue, and manufacturing of the model is completed; S5, a small rubber bag is arranged in the model, an injector is connected with the small rubber bag arranged in the brain model through a plastic conduit, and the volume of blood in the rubber bag is adjusted to simulate variation of hematoma. According to the manufacturing method, manufacturing is convenient, the result of electromagnetic waves passing through the multilayer-uneven-structure brain can be really responded, the actual condition of brain hematoma can be really simulated, and the manufacturing method can be used in the brain hematoma monitoring technology based on electromagnetism.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and relates to a method for making a multilayer non-uniform structure cerebral hematoma model. Background technique [0002] In clinical medicine, cerebral hemorrhage is a brain disease with high morbidity and mortality. There are many reasons for cerebral hemorrhage, including high blood pressure, cerebrovascular malformation, and traumatic brain injury. Spontaneous cerebral hemorrhage is one of the main diseases that threaten the health of middle-aged and elderly people. With the aging of the population, cerebral hemorrhage has an explosive growth trend. In patients with cerebral hemorrhage, hematoma expansion and rebleeding are common clinical situations. As the hematoma increases, it will cause irreversible and serious damage to the brain, or even death. [0003] Because the dielectric constant and conductivity of blood are significantly greater than the average tissue of the brain, som...
