Sphygmomanometric cuff pressurizing system

Abstract From the Canadian patent

Abstract, An inflatable, deflatable cuff worn by the subject, is, coupled to an air reservoir which is at a predetermined pressure which is above systolic pressure. The pressure head is established by a pump mechanism preferably located within the reservoir. When the reservoir is operatively coupled to the cuff, the cuff quickly inflates to a desired artery-occluding initial pressure preparatory to a following blood pressure measuring cycle of operation. The air pump resumes air flow into the reservoir when pressure within the reservoir falls below a predetermined threshold in preparation for a subsequent measurement cycle. The pump also supplies air directly to the cuff should the …
