The invention discloses a teaching model for
human body hepatic portal vein system anatomy and a demonstrating method of the
human body hepatic portal vein system based on the model. The structure comprises a model box, an
organ model and a
vein system model are arranged in the model box, the
organ model is composed of models of part of human organs, the vein
system model is composed of vein models with the constitution being the same as that of the
human body hepatic portal vein system, the vein models are hollow tubes made of a transparent material,
LED lamp strips are arranged in the vein models in a penetrating manner, the
LED lamp strips are connected to a power supply controller, and switch buttons used for controlling power supplies of the
LED lamp strips are arranged on the power supply controller. According to the technical scheme, through the combination of sound, light and shape, the human body
hepatic portal vein anatomy and
blood circulation during the hepatic portal veinhypertension can be completely, accurately and intuitively displayed, so that a student can more easily understand the complicated
anatomy structure, through practical teaching
verification, the learning progress and understanding of the student for the relevant knowledge of the human body
hepatic portal vein can be accelerated and deepened, in addition, the model device is integrally arranged inthe box, and thus teaching transfer is facilitated.
