A hydrostatic finger cuff for blood flow property analysis is provided which includes an elongated substrate member which has a pair of opposing long edges and a pair of opposing short edges. The hydrostatic finger cuff is configured to form a frustoconical shell when the ends of the cuff are overlapped and releasably connected together. The interior of the frustoconical shell conforms to the shape of the middle phalange of a finger and the first phalange of a thumb. ODavne side of the elongated member has an inflatable member that has a pressurizable interior region. A tube is fixed to the inflatable member and is in pneumatic communication with the interior of the inflatable member inflatable to a maximum of no more than 60 mmHg. The inflatable member completely circumscribes the finger and provides substantially uniform contact across the entire length of a phalange, in particular, the middle phalange of the middle finger. A pressure relief member is in fluid communication with the inflatable member, and is set to open and release pressure at a pressure level no higher than 1.2 psi.
