A sphygmomanometer is a medical tool that measures blood pressure in the artery. A sphygmomanometer typically comprises of:
The inflatable cuff wraps around the arm, and then a bulb inflates the cuff to collapse and then release the artery beneath the cuff in a controlled fashion. A measuring unit like a mercury panel or aneroid gauge indicates the pressure. A stethoscope is used when using the auscultatory technique to listen to the arterial blood flow sounds. At Health Products For You, we have different types of sphygmomanometers and aneroids - palm-held, wall mount, single-patient use, and much more. They are portable and can be easily used at the home, office, or while on the go. Take a pick that best suits your requirements!
Mercury sphygmomanometer is the most commonly used blood pressure apparatus and is considered the gold standard in the health industry. They gained popularity as they show more accurate reading than any other blood pressure machine. A manually Inflatable cuff is attached to the measuring unit with a mercury-filled tube. For an accurate reading, the apparatus needs to be placed on a flat surface and upright. This device does not require calibration. In many countries, it is banned owing to the mercury that can potentially cause hazards.
As the name suggests, it is without liquid. Aneroid sphygmomanometer does not use mercury and is considered safer than mercury sphygmomanometer. It requires periodic calibration. In this device, an inflatable cuff is attached to a dial gauge with tubing. Aneroids require careful handling as it uses delicate mechanism. Various types of aneroids available, like pocket aneroid, palm-held aneroid, wall mounted aneroid, etc., depending on how they are used. Medline Premier Handheld Aneroid and Graham-Field Mobile Aneroid Sphygmomanometer can be used to get accurate blood pressure readings.
A digital sphygmomanometer uses oscillometric measurements and an electronic pressure sensor to measure blood pressures. The reading is displayed on a monitor. The digital device also comes with inflatable cuffs but does not require pumping and the machine automatically evaluates and measures the fluctuations of arteries. This device is perfect for home use as it is extremely easy and convenient to use.
We at Health Products For You offer high-quality sphygmomanometers and aneroids from established manufacturers like Mabis DMI healthcare, Graham-Field Health Products, McKesson, Medline Industries, and many more.

Sphygmomanometers register blood pressure using a mercury column.
Parts of a Sphygmomanometer:
For accurate Measurement, it is not necessary for the gauge needle to rest at zero point but please make sure that the gauge needle should rest within the area of zero square prior to use. The zero square itself reflects the warranty for accuracy, i.e. ± 3 mmHg.
Yes, sphygmomanometer unit should be calibrated regularly for at least once a year.
The wrong cuff size will lead to inaccurate blood pressure measurement since the initial pressure given for the measurement may vary depends on how large the arm circumference is. When the cuff size is right the white index line comes in the range between the arrows after the cuff has been put on.
