Abstract (en)
[origin: WO2021086497A1] Disclosed is a finger cuff connectable to a patient's finger to be used in measuring the patient's blood pressure by a blood pressure measurement system utilizing the volume clamp method. The finger cuff may comprise: a pleth cuff; a bladder cuff; an optical source and an optical sensor pair mounted in the pleth cuff, wherein the optical source and the optical sensor pair generate a pleth signal from the patient's finger; a bladder mountable within the bladder cuff, wherein the patient's finger abuts against the bladder of the bladder cuff; and a controller. The controller to control pressure applied by the bladder to the patient's finger based upon measuring the pleth signal received from the optical source and sensor pair to keep the pleth signal approximately constant to replicate the patient's blood pressure to implement the volume clamp method and to measure the patient's blood pressure.
