Digital Cuff Apparatus For Determining Blood Pressure Without Use Of A Stethoscope

US Patent:
4331155, May 25, 1982
Filed:
Jan 2, 1980
Appl. No.:
6/109051
Inventors:
Alvin H. Sacks - Los Altos Hills CA
International Classification:
A61B 502
US Classification:
128686
Abstract:
A cuff having a casing and an inflatable diaphragm is slipped over a portion of the body of the user, preferably a thumb or finger. The diaphragm is connected by a conduit to a pressure source and to a manometer. A preferred pressure source is as a cylinder similar to that of a syringe. A plunger in the syringe inflates the diaphragm. The pressure in the cuff is slowly increased until the subject first notices a slight localized throbbing sensation within the artery inside the cuff, the pressure corresponding to diastolic blood pressure, and this pressure is read. Use of a transducer or even a stethoscope is unnecessary. Further, it has been found that if the cuff is properly designed, pressure corresponds very closely to diastolic blood pressure measured at the brachial artery with a standard arm cuff using a stethoscope. For other cuff structures the pressure in the cuff may be calibrated to that in an arm by using these subjective sensations. The pressure is increased further until the subject senses the disappearance of the localized throbbing within the artery, a condition which corresponds to systolic blood pressure, such pressure again being noted.

Method And Apparatus For Determining Blood Pressure

US Patent:
4202347, May 13, 1980
Filed:
Oct 11, 1977
Appl. No.:
5/841241
Inventors:
Alvin H. Sacks - Los Altos Hills CA
International Classification:
A61B 502
US Classification:
128677
Abstract:
It has been found that most subjects can sense the onset and cessation of the conditions in a blood vessel which give rise to the Korotkoff sounds used in blood pressure determination without use of a stethescope or any transducer and thus adequately read their own blood pressure using the blood pressure device. An inelastic cuff encircles a thumb or other portion of the subject's body and contains a diaphragm which is inflatable. A syringe-like member is connected to the diaphragm. Indicia on the barrel in accordance with the Perfect Gas Law indicate pressure at the onset and cessation of localized arterial sensations corresponding to Korotkoff sounds to afford readings of diastolic and systolic pressures. Zeroing of the indicia is provided to accommodate different sizes of thumbs, etc.
