为了使同学们能够具体、直观、深刻地了解人体血液循环基本情况,我们研制了较理想的人体血液循环模式教具,现将制作和使用方法介绍如下,以供参考。一、取材和制作1、取长0.9米,宽0.5米纤维板一块,固定在木头框架上(或用木板),板的正面涂上一层白漆,再在板的上端约60厘米高的部位处画上人体躯干轮廓,并涂上近似人体肤色的油漆,在胸腔部位再画上浅红色的心脏轮廓图。在左心室内钻两个孔,使作为血管的塑料管的始端和末端从两孔通向板的背面。血液循环的起点选取左心室,有利于配合血循环路线的讲述。
In order to make the students understand the basic situation of human blood circulation in a concrete, intuitive and profound way, we have developed the ideal human blood circulation pattern teaching aids. Now we will make and use the methods as follows for reference. First, draw and make 1, take 0.9 meters long, 0.5 meters wide fibreboard, fixed in the wood frame (or board), the front of the board coated with a layer of white paint, and then the upper plate about 60 cm high Painted on the human body trunk contour, and painted the body color of paint approximation, in the chest cavity and then painted light red heart contour map. Two holes were drilled into the left ventricle to allow the beginning and the end of the plastic tube as a blood vessel to pass from the two holes to the back of the plate. The starting point of blood circulation to select the left ventricle, help with the description of the blood circulation route.
