Description

A blood pressure pulse measuring system

technical field

The utility model relates to the technical field of blood pressure pulse measurement, in particular to a blood pressure pulse measurement system. the

Background technique

The traditional pulse measurement adopts the pulse diagnosis method, and the traditional Chinese medicine pulse diagnosis technology is an effective application of pulse measurement in traditional Chinese medicine, but it is affected by human factors and the measurement accuracy is not high. The digital pulse tester is a non-invasive measurement or indirect measurement. Its important feature is that the detection part of the measurement does not invade the body and does not cause body trauma. It usually measures the physiological parameters of the human body indirectly outside the body, especially on the body surface.

There are generally two methods for measuring blood pressure today: one is a penetrating blood pressure measurement method; the other is a non-penetrating blood pressure measurement method. Non-penetrating blood pressure measurement is divided into fuzzy memory method and first vibration sound measurement method. Although among the numerous blood pressure measurement methods, the most accurate measurement method is the penetrating measurement method, but the penetrating measurement not only has certain risks, but also requires high-level human resources. Therefore, such measurement methods are also limitedly used in large general hospitals. The simple and convenient mercury column blood sample measurement method is generally used in hospitals now, but because mercury itself is also dangerous, electronic sphygmomanometers will gradually replace mercury sphygmomanometers.
