1. Vital signs monitor comprising:
- (a) a sensor for sensing the heart beat and blood pressure of a patient and producing electrical pulses in a waveform indicative of the heart rate, systolic blood pressure, and diastolic blood pressure,(b) a computer for receiving the electrical waveform pulses from the sensor, converting the waveform pulses into digital signals and calculating a rate-pressure product which is the product of the heart rate and the systolic blood pressure, said computer comprising;
(1) control means for counting the heart beats of the patient, averaging the heart rate, blood pressure and rate-pressure product for a plurality of heart beats and causing said averaged rate-pressure product valve to be displayed on the display screen,(2) a heart beat memory connected to the control means for determining the number of heart beats that constitute the rate-pressure product averaging value to be displayed on the screen,(3) keyboard control switches for programming the heart beat memory to set the number of heart beats to be averaged, and(4) a digital display screen connected to the computer for visually displaying the heart rate, blood pressure and rate-pressure product in digital form.

Abstract
A vital signs monitor which includes a sensor which is applied to the main artery of a patient for detecting the heart beat and blood pressure and producing electrical pulses in waveform. A computer is connected to the sensor for receiving the waveform pulses, converting the waveform pulses into digital signals and calculating the heart rate, blood pressures and rate-pressure product. A visual display screen is connected to and controlled by the computer for displaying the heart rate, blood pressure and rate-pressure product in digital form.
