1. An electronic blood pressure and pulse rate measuring device for use on a subject by a user who can be said subject or another person and that can be used with battery power or ordinary available home and office current which comprises, in combination;

  • an inflatable-deflatable circumferentially adaptable arm-cuff with detachable acoustical transducer means to detect the first appearance of the Korotkoff sounds and the disappearance of the Korotkoff sounds including the series of Korotkoff sounds occuring therebetween for measuring the systolic and diastolic blood pressure and pulse rate of the subject, a pressure sensing means for transforming the degree expressed in millimeters of mercury of the pressure of the cuff upon the subjected arm to correlate with both analog and digital readings indicative of the first appearance and the disappearance of the Korotkoff sounds produced by the semioccluded artery and its gradual deocclusion process, a pressure threshold setting means which can electronically be programmed or set by the user at about the equivalence of 20 millimeters of mercury reading or higher above the anticipated highest systolic blood pressure reading of the subject, whereupon said programmed threshold reading upon having been exceeded by the arm cuff'"'"'s compression pressure exerted therearound the arm or limb of the subject, said pressure threshold setting means will automatically trigger or activate the electronic circuitry of the system to sense for and latch the systolic and the diastolic readings by a systolic enabling circuit and a diastolic enabling circuit, respectively and, within the time frame of the systolic and diastolic measurement, means for calculating arithmetically the pulse rate per minute of the subject based on the pulses and rate of the appearance of the Korotkoff sounds as picked up by the acoustical transducer means, a physical activity degree delineation means that enables the user to program the degree of physical activity of the subject during the time and data of the blood pressure and pulse rate measurement, so that upon entry and storage of this valuable data in correlation with the subject'"'"'s ID number and the date and time of blood pressure and pulse rate measurement, it is possible to retrieve or recall the the combinations of those data at a later date for comparative purposes, an emotional stress degree delineating means that enables the user to program the degree of emotional stress of the subject during the time and date of the blood pressure and pulse rate measurement, so that upon entry and storage of this valuable data in correlation with the subject'"'"'s ID number and the data and time of blood pressure and pulse rate measurements, it is possible to retrieve or recall the combinations of these data at a later date for comparative purposes, means of recalling the desired combination data either singly or in multiples in forward sequential or rearward sequential order relevant to a pre-programmed rate of consecutive appearances of data display, important for use by user for comparative purposes, a means for calculating the regularity or irregularity of the pulse rate including means for entering and storing pulse rate regularity and irregularity data and retrieving of the same at a later date, light emitting means for visually establishing the range between the systolic blood pressure reading and the diastolic blood pressure reading by the appearance of a plurality of continuously latched light signals starting from the systolic blood pressure reading to the diastolic blood pressure reading as correlated to a linear gauge enabling the user the capability of a visual representation of the approximate range and disparity between the subject'"'"'s systolic and diastolic readings, a means of programming the correct right or left arm location where the blood pressure is being taken, respectively during the blood pressure measurement, before and during entry of this data into memory together with the other data relevant to a particular subject so that upon future retrieval of the combination of this data, the user can be reminded from which arm the particular blood pressure was taken according to the particular time and date of measurement.
