Study on the Depth, Rate, Shape, and Strength of Pulse with Cardiovascular Simulator
نویسندگان
چکیده
Pulse diagnosis is important in oriental medicine. The purpose of this study is explaining the mechanisms of pulse with a cardiovascular simulator. The simulator is comprised of the pulse generating part, the vessel part, and the measurement part. The pulse generating part was composed of motor, slider-crank mechanism, and piston pump. The vessel part, which was composed with the aorta and a radial artery, was fabricated with silicon to implement pulse wave propagation. The pulse parameters, such as the depth, rate, shape, and strength, were simulated. With changing the mean pressure, the floating pulse and the sunken pulse were generated. The change of heart rate generated the slow pulse and the rapid pulse. The control of the superposition time of the reflected wave generated the string-like pulse and the slippery pulse. With changing the pulse pressure, the vacuous pulse and the replete pulse were generated. The generated pulses showed good agreements with the typical pulses.

Effect of Cell Size and Shape on Electric Field Threshold and Critical Transmembrane Voltage for Electroporation
Introduction: Electroporation is a technique for increasing the permeability of the cell membrane to otherwise non-permeate molecules due to an external electric field. This permeability enhancement is detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the pulse strength threshold. In this study, the variabil...
