Abstract: A closed blood pressure cuff including a ring-shaped inflatable bladder having an inner portion for making direct contact with a user's arm and an outer portion having a fixed circumference outside the inner portion. The bladder is formed of non-distensible material, preferably by joining a tubular starting element. The inner portion of the bladder is not constrained during inflation and thus can readily conform to a subject's limb, the outer portion accommodating an upper limit of arm circumference within the cuff. The cuff may include a stiffener attached to the outer portion of the bladder to automatically adjust the shape of the bladder during inflation. The stiffener may be in the form of a continuous layer or may comprise a plurality of axial ribs, allowing the cuff to be folded when not in use. The cuff may be generally cylindrical or may be tapered.

Abstract: A blood pressure cuff including an inflatable bladder disposed between an elastic, resilient inner layer of material and at least one outer layer of material. The bladder is secured to these layers along the elongate ends but not along the elongate edges. The bladder is not laterally constrained during inflation. The cuff is formed into a cylindrical shape having a fixed outer diameter and includes a backing layer and apparatus for securing the bladder to a layer of the cuff to hold the bladder in place during donning of the cuff. Because the bladder is not constrained along its contact-width edges, the shape of the bladder automatically adjusts to provide a longer contact surface for larger arms and a shorter contact surface for smaller arms. The cuff is especially suited for use as a closed cuff in an automated blood pressure measurement machine or in stand-alone measurement use.

The bladder is secured to these layers along the elongate ends but not along the elongate edges. The bladder is not laterally constrained during inflation and can readily conform to a subject's limb. Preferably the cuff is formed into a cylindrical shape having a fixed outer diameter selected to accommodate an upper limit of arm circumference within the cuff. The cuff may include a stiff backing layer and means for securing the bladder to a layer of the cuff to hold the bladder in place during donning of the cuff by a subject.

Abstract: A harness is provided for holding a blood pressure cuff in the correct position on the arm when being worn for extended periods of time. The harness has a support member that attaches by clasps directly to the cuff on the person's arm. The support member extends from the cuff to the shoulder region of the user so that the weight of the cuff is carried by the shoulder rather than by the arm through contact pressure from the cuff itself. The support member prevents slippage or rotation of the cuff throughout the monitoring period. A strap is provided that attaches to the support member at the shoulder region and runs under the other arm of the user to hold the support member in the correct position.
