Abstract:
The study of pulse wave, including its quantitative analysis and propagation, is one of the hot topics in the fields of clinical medicine, such as how to detect cardiovascular diseases and make early diagnosis without harm. In this paper are discussed a new type of automatic cardiovascular diagnosis method and the corresponding test instrument. The cardiovascular system parameters can be achieved through the wave changes, related data processing and analyzing. This system includes piezo-film transducer, signal amplifier, data collecting and data analyzing equipment. Various pulse diagrams can be shown in omnidirectional and multifunctional ways. The measurement error can be reduced effectively by introducing Mini-wave analysis in the design of software. The research indicates that combination of this equipment with the traditional Chinese medicine will provide wide practical application.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
