施新猷介绍的血压放大装置对提高实验教学效果很有帮助.但该装置所需的白金丝氖泡等材料,有些实验室不易配备.我们在原装置基础上增加了一个绝缘用检压计.血压放大检压计上用直径≤0.3mm 钢丝代替白金丝,导线间距为普通水银检压计的1/2.放大塔指示采用3 W 荧光灯管.实验开始前将记录用检压计、绝缘用检压计、放大检压计分别装水银至刻度零处.绝缘检压计与放大检压计之间藉一“⊥“型玻管相连,连接处玻管口与玻管口靠紧.其内充满液体石腊,拧紧“⊥”型玻管上端胶管的螺旋夹.调节检压计零点与实验动物心
The blood pressure amplifying device introduced by Shi Xinfang is very helpful to improve the experimental teaching effect, but some materials such as white gold wire and neon bulb needed by the device are not easy to be equipped in some laboratories, and we have added an insulation checker on the original device. Check the pressure gauge with diameter ≤0.3mm wire instead of platinum wire, wire spacing for the ordinary mercury valemeter 1/2. Amplifier indicates the use of 3 W fluorescent tube. Before the start of the experiment will be recorded with a checker, insulation with a pressure Meter, enlarge the checker were installed mercury to the mark zero.Insulation between the checker and the magnification of a pressure gauge by a “⊥” type glass tube connected to the glass tube port and the glass tube mouth close .Full inside Liquid paraffin, tighten the “⊥” type tube upper hose clamp. Adjusting the zenith zero and experimental animal heart
