Antique Sphygmomanometers: A Collector‘s Guide221

Sphygmomanometers, or blood pressure monitors, are essential medical devices used to measure blood pressure. While modern digital sphygmomanometers are widely used today, antique sphygmomanometers offer a fascinating glimpse into the history of medical technology and can be valuable collector's items.

Types of Antique Sphygmomanometers

There are several types of antique sphygmomanometers, each with its unique characteristics:
Mercury Sphygmomanometers: These classic sphygmomanometers use a column of mercury to measure blood pressure. They are considered the most accurate type of sphygmomanometer but can be dangerous if the mercury spills.
Aneroid Sphygmomanometers: Aneroid sphygmomanometers use a mechanical gauge to measure blood pressure. They are portable and easier to use than mercury sphygmomanometers but may be less accurate.
Spring Sphygmomanometers: Spring sphygmomanometers use a coiled spring to measure blood pressure. They are the simplest and most inexpensive type of sphygmomanometer but are the least accurate.

History of Sphygmomanometers

The first sphygmomanometer was invented in 1881 by German physician Samuel Siegfried Karl von Basch. This device used a water-filled rubber tube to measure blood pressure. In 1896, Italian physician Scipione Riva-Rocci improved upon von Basch's device by using a rubber cuff inflated with air instead of water. This design is the basis for the majority of sphygmomanometers used today.

Antique sphygmomanometers were often made of brass or wood and featured intricate designs. They were used in hospitals, clinics, and homes for decades until they were replaced by more modern electronic devices.

Collecting Antique Sphygmomanometers

Antique sphygmomanometers can be valuable collector's items, especially rare or well-preserved models. When collecting antique sphygmomanometers, it is important to consider the following factors:
Type: Mercury sphygmomanometers are generally more valuable than aneroid or spring sphygmomanometers.
Condition: The condition of the sphygmomanometer is also important. Well-preserved sphygmomanometers with all original parts are more valuable.
Rarity: Some models of antique sphygmomanometers are rarer than others. Rare models are more desirable to collectors.
Aesthetics: The aesthetics of the sphygmomanometer can also affect its value. Sphygmomanometers with unusual or decorative designs are more valuable.
