Sir, i am a physician and searching for a pen like size ultrasonic device to detect the arterial pulse. the reason of my search is that i have a neurologic disease that has affected the sensation of my fingers. my only requirement for the device is to produce a rythmic sound according to the arterial pulse when the pulse is detected and, if possible, the intensity of the sound to be analogous to the blood pressure (assuming that the user applies a certain pressure by the device to the skin and tissues overlying the artery). is it possible for me to find such a device? please, spend some of your time to give me your advice. thanks for your attention, yannis.
