摘要：
Disclosed is a finger cuff connectable to a patient’s finger to be used in measuring the patient’s blood pressure utilizing the volume clamp method. The finger cuff may comprise: a finger cavity to receive the patient’s finger; a micro-laser and a detector to measure a pleth signal; a bladder mountable within the finger cavity, wherein the patient’s finger received in the finger cavity abuts against the bladder; and a processor. The processor may be configured to control pressure applied by the bladder to the patient’s finger based upon measuring the pleth signal received from the detector and the micro-laser 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.
