Sphygmus dynamic image information collecting system

Abstract

A pulse dynamic image acquisition system involves herbalist medicine diagnosis device, especially the pulse information collection devices. The sealed pressure cavity is fixed on the level bracket, and the level bracket is fixed on the vertical columns. Flexible contact is fixed on the top of the sealed pressure cavity, the air pump is linked with the air pressure buffer cavity and the air pressure buffer cavity is linked with the sealed pressure cavity by the air circuit. The membrane with veins is affixed to the lining of the flexible contact, the lighting is fixed in the sealed pressure cavity the where above the flexible contact. The image acquisition device is installed on the upside of sealed pressure cavity, and the image acquisition devices connected with the computer through the signal line. A piece of ground glass is fixed between the lighting and the flexible contact. The invention can detect the image of the skin surface of the position where it feels the pulse when pulse throbs, and then gets multi-dimensional, comprehensive and dynamic image information of pulse.

Description

Technical field [0001] The invention relates to a traditional Chinese medicine diagnostic device, in particular to a pulse information collection device. technical background [0002] The sensors currently used for pulse information collection mainly include: liquid, photoelectric, strain, and PVDF sensors. The liquid sensor is a pressure-sensitive surface made of a film that deforms after being pressed, causing the conductive liquid column inside the container to rise and fall, and the resistance value changes, thereby converting the pulse pressure signal into an electrical signal. The photoelectric sensor is forced by a thin rod and moves upward to change the amount of light transmitted. The electrical signal output by the photocell reflects the force. Strain gauge pressure sensor is a kind of sensor that is widely used in pulse meter. It deforms after being stressed by the strain gauge, which causes the resistance value to change, and the change in the output voltage of the br...

Problems solved by technology

These improved detection methods are greatly limited by the number of detection points due to the influence of factors such as the sensor structure volume, the performance of sensitive components, and the manufacturing process.

At present, there are only research reports on five-way sensors and 9-point PVDF pulsometers, and it is difficult to have a linear relationship between the output of the sensor and the skin deformation caused by the pulse when cutting the pulse.

Obviously, the pulse map collected by the above-mentioned detection system is difficult to quantitatively and accurately reflect all the constituent elements of the pulse condition, which restricts the research on the objectivity of TCM pulse diagnosis and the application of pulse information.
