Abstract：The paper researched and developed a kind of leak-proof device for mercury
sphygmomanometer, which could effectively prevent mercury from overflowing. The main principle
of the device was installation of a L-type sheetmetal in the mercury pot valve of the desktop mercury
sphygmomanometer. When the valve was in the ON and OFF state respectively, the cover of the switch
would be affected through the sheetmetal’s formation of limit and no limit protection. According to
the application results, the device could effectively prevent the mercury from overflowing, reduce the
maintenance cost, avoid environmental pollution and harm to health. Additionally, it also demonstrated
its well-designed and simply-structured features with the advantages of low cost, good stability, durability
and generality, which was of great promotion and application value.
