Classic sphygmomanometer ideal for any household! health professionals still prefer the accuracy and reliability of the old-fashioned squeeze-bulb style of blood pressure monitors. This type of gauge is known as a "sphygmomanometer," and "aneroid" means it uses a dial rather than a column of mercury. Home users, medical professionals and those in training to become health professionals, will all love this all-in-one kit. It includes everything you need, including cuff, aneroid dial with index and range markings, gauge holder, inflation bulb, thumbscrew release valve, the all-important stethoscope and several extras. The Sprague stethoscope is professional-quality as well, with two heads for respiratory and cardiovascular use and dual tubes for best sound transmission. Easy to use: there are a few steps to using this classic style of blood pressure gauge, but this kit comes with an easy-to-understand instruction manual that tells you everything you need to know. Notes: using a dual head stethoscope, the user needs to rotate the chest piece through 180 degrees (click sound when in position). Open either the bell or diaphragm for usage and close the other. Package includes : 1x aneroid sphygmomanometer, 1x stethoscope , 2x extra diaphragms, 4x extra stethoscope ear tips, 3x stethoscope bells: small, medium and large for infants, children and adults, 1x carry-case , 1x instruction manual.
