It is easy and quick to use and is increasingly widely used.

[0003] A mechanical sphygmomanometer is a medical device used in conjunction with a stethoscope to measure human blood pressure. The sphygmomanometer head consists of a movement, a diaphragm, a dial, a pointer, and a case. The diaphragm converts the gas pressure to be measured into mechanical displacement, the movement converts the mechanical displacement generated by the diaphragm into the mechanical rotation of the gear shaft, and the pointer fixed on the gear shaft indicates the gas pressure on the scale printed on the dial. The movement, diaphragm, and dial are all installed in the case. The mechanical sphygmomanometer has the advantages of simple structure, easy maintenance, high reliability, and low price, and has been widely used.
