Difference Between Soft Silicone Anatomical Model And PVC Anatomy Model

Human anatomy models and animal anatomical models have always been in the field of medical education in the demonstration props, the role is self-evident, from plaster models, FRP models, resin models, pvc models to today's popular silicone models, products are constantly updated, quality all the way up, the price is also uneven, many people do not understand the mechanics, in fact, all this comes from the change of material, material determines quality, Floating price, affect the effect of use, refresh the market. The following is a brief talk about the characteristics of the two common material models.

 

1. Features of PVC Anatomy Model

 

The main material of PVC anatomy models is made of PVC powder and oil, color paste mixing and blending, and the raw materials are heated and cooled by micro-injection glue dropping process. PVC soft rubber has the difference between ordinary material and environmental protection material, environmental protection material is also called ATBC-PVC, can pass some lower standards of environmental protection certification, but there are also some toxicity, can not be used in the field of food and cosmetics. The texture of PVC anatomy model is generally hard, and can only simply reflect the shape of human tissues, but can not directly and objectively express the hardness of different tissues of the human body.

 

PVC anatomical models feel hard, no toughness, and the appearance is slightly rough, so the simulation effect of PVC model products is poor, the fidelity of the display is limited, there is a certain deviation in the process of teaching and display, and the feel effect and experience are not good. In addition, due to the characteristics of plastic texture, the model is easy to embrittlement and damage, which is not conducive to storage, cleaning and use.

 

PVC anatomy model use traditional methods to use paint on the surface of the model coloring, and due to the poor heat stability and light resistance of PVC materials, it is easy to decompose into hydrogen chloride under high temperature conditions and fade, ungel phenomenon, the display structure is not clear, which is not conducive to long-term teaching use.

 

 

The Features of Soft Silicone Anatomical Models

 

Soft silicone anatomy models are mainly made of silicone rubber and its auxiliary chemical products, through the ROHS certification is currently the most safe and environmentally friendly category of chemical materials in the rubber and plastic industry, and soft silicone rubber through the FDA certification, in line with environmental standards, can be used in the field of food and cosmetics. Therefore, soft silicone anatomy model products are non-toxic and tasteless. And the soft silicone model products use different degrees of silicone to reflect the different organs of the human body, so that the soft silicone model can more intuitively reflect the internal structure of the human body organs; The image is more realistic.

 

 

Soft silicone anatomical model products feel soft, toughness and good elasticity, smooth appearance, color, brightness. Because the silicone material has many other similar materials difficult to replace the characteristics, its high adsorption performance, good thermal stability, chemical stability, and high mechanical strength, so the production of the model is strong and durable, the surface of the product can not see pores, with smooth and realistic feel and accurate shape, convenient teaching display and simulation anatomy training, It is very scientific and practical.

 

Meiwo soft silicone anatomical model is formulated according to the proportion of food-grade silicone, and the corresponding mold parts are filled with color painting according to the different colors of each organ on the produced mold. The arteries (red), veins (blue) and nerves (yellow) in the product are formed by color separation filling and perfusion, which is not a conventional dyeing method and does not fade. Muscle organs and other parts according to the color of perfusion molding. It has the characteristics of accurate structure display, repeated bending, durable, easy to disassemble and clean, and each medical soft silicone anatomical model is equipped with two-dimensional code, which can be combined and split, stripped layer by layer, learned deep knowledge structure, and deeply combined with clinical teaching content, to achieve multi-clinical, early clinical, repeated clinical. Each model has high-definition photography, three-dimensional scanning, equipped with two-dimensional code identification plate, physical model digitalization has 360 degree rotation, flipping, translation, free to enlarge, reduce, drag, annotation, splitting, voice, resource link, independent display and other functions, smooth operation, support the Internet, mobile phone and other network use. At the same time, it also supports resource link comparison on the same screen, online structure annotation test question practice function, improve the user's structure recognition ability.

 

 

From the above comparison, it can be seen that the performance and cost performance of soft silicone anatomical model are more prominent, and will become the master and leader of the material model market.
