Blood circulation simulation device

Abstract

The invention discloses a blood circulation simulation device which comprises a liquid containing box, a pressure pump, a communicating pipe, a filter screen, an artery simulation pipe, a particle catheter, a particle containing box, a sealing plate, a vein simulation pipe, a return pipe and a capillary simulation pipe. Liquid in the liquid containing box is red, the pressure pump is communicated with the liquid containing box through the communicating pipe, a filter screen is arranged on the left side of the communicating pipe, an artery simulation pipe is arranged on the right side of the pressure pump, a particle guide pipe is arranged on the upper side of the artery simulation pipe, a particle containing box is arranged on the upper side of the particle guide pipe, and a sealing plate is arranged in the particle guide pipe, the vein simulation tube is communicated with the artery simulation tube, a backflow tube is arranged on the vein simulation tube, a capillary simulation tube is arranged on the right side of the artery simulation tube, and the capillary simulation tube is communicated with the liquid containing box. The device can show the blood circulation system to students through real objects, is simple in structure, easy to operate, low in investment cost, safe and efficient, and reduces the working difficulty of pathology teaching.

Description

technical field [0001] The invention relates to a pathological experiment equipment, in particular to a blood circulation simulation device. Background technique [0002] The blood circulatory system includes the heart, arteries, capillaries and veins. The blood circulatory system is a complete closed circulatory channel. It is centered on the heart and connected with various organs and tissues of the whole body through blood vessels. The blood circulates in it. The heart is a hollow It is a muscular organ that constantly contracts and relaxes regularly, continuously inhales and extrudes blood, and ensures that blood flows forward in one direction along the blood vessels. [0003] In the pathology teaching experiment, the teacher needs to draw a schematic diagram of the blood circulation system to the students through pictures or hand-drawn lines, and then show the students the whole process of blood circulation, which cannot be fully displayed through a single picture or ha...

[0003] In the pathology teaching experiment, the teacher needs to draw a schematic diagram of the blood circulation system to the students through pictures or hand-drawn lines, and then show the students the whole process of blood circulation, which cannot be fully displayed through a single picture or hand-drawn lines How blood circulates throughout the system, and some common blood diseases cannot be displayed through pictures and hand-painted lines, which affects students' knowledge and understanding of experimental learning, and increases the difficulty of pathology teaching in the long run
