Abstract: A non-invasive blood pressure monitoring system is disclosed herein. The non-invasive blood pressure monitoring system includes a pressure cuff comprising a resistive portion and a conductive portion aligned with the resistive portion. The non-invasive blood pressure monitoring system also includes a controller operatively connected to the pressure cuff. The controller is adapted to estimate the circumference of the pressure cuff based on the position of the conductive portion relative to the resistive portion.

Abstract: An apparatus, system and method for collecting non-invasive blood pressure readings from a patient is provided. A non-invasive blood pressure cuff is arranged to be worn about a wrist of a patient and to be operatively connected to a blood pressure monitor. Communication means are operatively connected to the blood pressure cuff the monitor and arranged to automatically communicate a parameter associated with the cuff to the monitor. The monitor is arranged to automatically adjust blood pressure algorithms based upon the parameter to enhance the accuracy of blood pressure readings.

Abstract: A conical blood pressure cuff having an integrated inflatable bladder is provided. The cuff is formed of a flexible compliant laminate having at least first and second layers which are impermeable to air. The cuff is formed having first and second arcuate edges, the second edge having a smaller radius than the first edge. Radial edges extend between the first and second arcuate edges. An air-tight rectangular pocket forms the inflatable bladder between the first and second layers. A tube is provided communicating with the interior of the pocket formed between the laminated layers. Air may be pumped the through the tube to inflate the bladder. Similarly, the bladder may be deflated by removing air from the pocket through the tube.

Abstract: A signal enhancing and artifact reducing blood pressure cuff for use during the non-invasive measurement of blood pressure. The non-invasive blood pressure cuff has an inflatable bladder and a semi-rigid insert disposed over an outer side of the inflatable bladder for enhancing a blood pressure signal by reducing blood pressure signal attenuation. The semi-rigid insert also acts to reduce the effects of external artifact on the inflatable bladder of the blood pressure cuff. The blood pressure cuff has the insert disposed over the outer side of the inflatable bladder to substantially cover the inflatable bladder when the cuff is wrapped around the limb of the subject. An optional damping device made of an impact absorbing material may be disposed over the outer side of the insert to further reduce the effects of external artifacts. A pocket may be formed over the outer side of the cuff to hold the insert.
