Pocket-size electronic cuffless blood pressure and pulse rate calculator

Abstract

Several related preferred embodiments pertaining to a non-invasive type of pocket-size electronic cuffless blood pressure and pulse rate calculator with optional temperature indicator, timer and memory are disclosed, for fast, accurate and reliable determination of both systolic and diastolic blood pressure values of the human or animal subject utilizing the 'Korotkoff method' of detection; pulse rate being determined independently or in conjunction with the blood pressure measurement; said device utilizing microcomputers and light-emitting display means such as, but not limited to, LED or LCD pressure display gauge representing the equivalence in millimeters of Hg. a range from 0 to 300. This disclosure is characterized by several models of compact construction and modernistic designs with minimal moving mechanical parts and with a preferrably linearly displaceable pressure head applying means for on-the-spot over-the-artery application, coupled with an optimally located acoustical transducer for detecting the 'Korotkoff sounds' created during the process of extravascular and occlusion and gradual deocclusion of the subjected pressurized artery; the device has a manually or electronically operable pressure threshold that can be set about 30 millimeters Hg. equivalence or more above the anticipated systolic pressure, and said pressure threshold capable of being entered into the microcomputer's memory to effect the automatic triggering of the systolic and diastolic electronic sensing and latching of the desired blood pressure data only after said pressure threshold has been reached.
