摘　　要：针对台式水银柱血压计长期存在的水银外溢难题,设计了一种新型不对称“V”型水银槽开关。该新型开关由左侧垂直臂、左侧水平臂、右侧水平臂和右侧垂直臂组成,其原理为测量血压时,“V”型开关的左侧水平臂逆时针绕轴心旋转90°到“打开”位置时,其左侧垂直臂处于阻碍血压计闭合的卡位位置,使用者只有测完血压并还原开关位置后,血压计的上盖才能顺利闭合,从而发挥强制性“提醒”的作用。这种“V”型水银槽开关的安全防漏装置设计合理,结构简单,便于应用在现有的台式水银柱血压计中,因此,通用性好,价格低廉,易于实现生产,此外,其具有操作简单,易于被用户接受和认可的优点,同时还可达到避免水银泄漏、保护环境的目的。Aiming at the long-standing mercury spillover problem of desktop mercury sphygmomanometer,this study designed a novel asymmetric"V"-shaped mercury tank switch that can solve this problem effectively.This novel switch is composed of a left vertical arm,a left horizontal arm,a right horizontal arm and a right vertical arm.The principle is that when measuring blood pressure,the left horizontal arm of the"V"switch rotate around the axes by 90 degrees counterclockwise to a specific position"open",the left vertical arm is in the locked position that prevents the sphygmomanometer from being closed,the upper cover of the sphygmomanometer can be closed smoothly only after the user has finished blood pressure measurement and reset the switch position,and thereby it can play the role of compulsory"reminding".As a safe and leak-proof device,this"V"-shaped mercury tank switch is designe d reasonably and simply,and it is fe asible to integrate with the present desktop mercury sphygmomanometer,therefore,it is versatile and low-cost and can be produced easily,besides,it can be operated easily and accepted and recognized by users readily,meanwhile,the goals of avoiding leak and protecting environment could be achieved,too.
