作者在讲人体解剖生理学血循环器官一章中“红血球和氧的运送”一节时,会试着把氧气和二氧化碳先后通入新鲜的鸡血里,满意的验证了血红蛋白的特性在教学的效果上是很好的。现在我把这个小实验介绍一下:先把血的抗凝剂柠檬酸钠溶液放在烧杯里,然后注入新鲜鸡血搅拌使它不凝固。同时,准备好制取氧气和二氧化碳的全套装置备用(氧可在试管中制取用氯酸钾和二氧化锰加热即可。二氧化碳在瓶中制取,用大理石加盐酸即可)。在讲到当血经肺泡毛细血管时,在氧气多的情况下,血红蛋白即与氧结合与二氧化碳分离,形成鲜血的动脉血。这时即将制出的氧气用玻璃管通入血中(或事先制好氧气贮于瓶中用时用排水取气法用管通入血中
In the chapter “Carrying Red Blood Cells and Oxygen” in the chapter on the anatomy and physiology of blood circulation organs, the author tries to pass oxygen and carbon dioxide into fresh chicken blood in succession, which satisfactorily verifies the effect of hemoglobin on the teaching effect. It is good. Now I will introduce this little experiment: First put the blood anticoagulant sodium citrate solution in a beaker, then inject fresh chicken blood and stir it so that it does not freeze. At the same time, prepare a complete set of equipment for preparing oxygen and carbon dioxide. (Oxygen can be prepared by heating with potassium chlorate and manganese dioxide in a test tube. Carbon dioxide is prepared in a bottle and hydrochloric acid can be added with marble). When blood is passed through the alveolar capillaries, hemoglobin is combined with oxygen to separate carbon dioxide from oxygen in the presence of much oxygen to form bloody arterial blood. At this time, the oxygen to be produced is introduced into the blood with a glass tube (or pre-prepared oxygen is stored in the bottle and used for drainage into the blood with a tube).
