A Mercury Blood Pressure Machine, also known as a mercury sphygmomanometer, is a traditional manual blood pressure measuring device that uses a column of mercury to indicate blood pressure levels. However, it's important to note that the use of mercury in medical devices, including blood pressure machines, has been phased out in many places due to environmental and health concerns associated with mercury exposure.
Components of a Mercury Blood Pressure Machine include:
-
Mercury Column: The vertical column of mercury in the gauge rises and falls based on the pressure exerted by the inflated cuff on the patient's arm.
-
Cuff: The inflatable cuff is wrapped around the patient's upper arm and is connected to the mercury column.
-
Glass Tube: The column of mercury is housed in a glass tube with a calibrated scale for measuring blood pressure.
-
Bulb: A hand-operated bulb (BP bulb) is used to inflate the cuff.
-
Valve: A release valve allows for controlled deflation of the cuff.
While mercury sphygmomanometers were historically widely used for blood pressure measurements due to their accuracy, they have been largely replaced by alternative devices that do not contain mercury. This transition is in line with environmental regulations and a focus on safer, mercury-free healthcare practices. Modern alternatives include aneroid sphygmomanometers or digital blood pressure monitors. If using a mercury device, it should be handled and disposed of with care to minimize the environmental impact.
