Measuring device based on programmable control companding

Abstract

The invention discloses a vascular condition measuring device based on programmable control companding. The device comprises two flexible detection terminals with ultrasonic transmitting-receiving capacity, a pneumatic companding bag, a control module, a detection module and a speed regulation air pump, wherein the pneumatic companding bag is connected with the control module, the control module is connected with the speed regulation air pump, and the detection module is connected with the control module. Determined pressure is applied to different positions of the companding bag by program control, transmission characteristics of blood vessels at the application positions are changed, the transmission characteristics of the blood vessels between a cardiac muscle and a pulse detection point are identified by active detection and channel inversion for the cardiac muscle and pulse point fluctuation, the transmission characteristics of local blood vessels at the application positions are identified according to the transmission characteristics of the blood vessels before and after pressure application and channel cascade characteristics, and conditions such as elasticity, occlusion and vascular wall thickness of the local blood vessels can be judged by the aid of characteristic extraction and characteristic comparison. The device has the advantages that measuring positions, companding modes and pressure strength can be controlled and the like.

Description

technical field [0001] The invention mainly relates to the technical field of blood vessel state detection, in particular to a blood vessel state measurement device based on program-controlled companding. Background technique [0002] Pulse diagnosis is a unique method of disease diagnosis in traditional Chinese medicine. Traditional Chinese medicine has been used to pulse diagnosis for more than two thousand years. It mainly uses the "inch-mouth diagnosis method" to understand the ups and downs of qi and blood in the viscera, meridians, and collaterals of the whole body. Three types of finger force are often used to measure the pulse: light force at the beginning, and floating when touching the skin. "Lift"; then press with moderate force to the muscles, which is called "seeking"; and then press hard to the muscles and bones, which is called "press". From the physical point of view, the wrist arterial pulse and its changes form a pulse wave, which is formed by the heartbea...

Problems solved by technology

However, the pulsation at most positions on the arterial vessel is not obvious enough, and its measurement results will affect the accuracy of subsequent vascular state detection
