Finger cuff having a shell

A blood pressure measurement system to measure a patient's blood pressure utilizing volume clamping comprising:

• a finger cuff connectable to a patient's finger, the finger cuff comprising:
• a shell having a finger cavity and a pair of opposed first and second top portions, the finger cavity of the shell placed under a patient's finger to receive the patient's finger, the finger cavity including a light emitting diode (LED)—photodiode (PD) pair, wherein the shell is fixed thereby not including rotatable sections;
• a bladder including a pair of openings, the bladder mountable within the finger cavity such that the pair of openings surround the LED-PD pair, respectively;
• and
• a clamping mechanism coupled to the opposed first and second top portions of the shell, the clamping mechanism to suitably clamp the patient's finger received in the finger cavity of the shell against the bladder mounted within the finger cavity of the shell such that the bladder and the LED-PD pair aid in measuring the patient's blood pressure by the blood pressure measurement system utilizing volume clamping.
