This is a standard match for doctors to measure blood pressure of patients.Either single head or dual head stethoscope can be selected attach to aneroid sphygmomanometer.

The sphygmomanometer is composed of cuff ,bladder , bulb and gauge which has good sealing and can ensure that its internal structure is free from mechanical damage and pollution invasion.

The sphygmomanometer is based on the deformation of the elastic element (capsule). Under the pressure of the measured medium, the capsule produces corresponding elastic deformation displacement. With the help of the ejector rod of the movement, it is driven and amplified by the gear transmission mechanism, and the measured value is indicated on the dial by the pointer fixed on the gear shaft of the movement. The method that doctors use stethoscope to measure the sound change of auditory artery pulse to measure human blood pressure is called "Coriolis auscultation", which is widely used all over the world. The basic principle of sphygmomanometer is "Coriolis sound". Its structure, purpose and working principle have been widely recognized by people and widely used in domestic and foreign markets.
