APPARATUS FOR DETERMININGBLOOD VELOCITY USING HALL ELEMENT PULSE DIAGNOSIS WAVE AND PHOTOPLETHYSMOGRAPH PULSE DIAGNOSIS WAVE

摘要

It is easier from magnetic hall element pulsimeter and plethysmogram detection from the speed that finger can detect blood flow the present invention relates to a kind of speed for measuring blood flow using the hall element sphygmometer of impulse waveform and plethysmograpy that human testing that can combine radial pulse waveform and quick. The equipment includes pulse wave sensing unit, the radius for sensing pulse; Plethysmogram measuring unit be installed on finger and also have detected the user of plethysmogram by using photo-plethysmograpy using characteristic absorption IR light by oxyhemoglobin (HbO& sub 2 /sub ) in alterial blood; Pulse wave unit and plethysmogram measuring unit are connected to microcomputer, the wrist radial artery part the distance between being previously entered and thumbnail, find the peak value and plethysmogram of peak value radial artery waveform, the time value is found out by subtracting each other, and length is found in wrist radial artery and thumbnail by the time value to the blood flow of rate. ;The 2014 of copyright KIPO submissions
