  • Patent number: 6162181
    Abstract: A method and assembly oscillometrically measures systolic, mean and diastolic blood pressures by inflating a form fitting cuff disposed over the Palmar Arch of the hand, and subsequently deflating the cuff stepwise, The arterial blood supply to the hand, which is very rich, lies relatively close to the surface of the palm. Cuff pressure oscillations can be sensed with an inflatable glove or mitten type cuff. A full or partial glove, mitten, or the like, with openings for reception of portions of the fingers and thumb can be used. Inflation of the cuff allows the assembly to be used to measure arterial blood pressure on either hand of a patient.

  • Patent number: 5727559
    Abstract: The vascular resistance to blood flow through the hand is increased in an essentially uniform manner by the application of pressure to the hand. The pressure is applied by means of an inflatable bladder mounted on an arm board or within a non-expandable sleeve, mitten or glove, which bladder covers at least the palm of the hand. Controlled inflation of the bladder conveys pressure to the hand tissue to a degree necessary to compress vascular structures and obstruct or restrict blood flow. By occluding blood flow through the hand, more accurate invasive blood pressure readings can be taken in clinical situations where decreased hand vascular resistance occurs.
