To permit loose and relaxed position of the hand of a patient over a vasometric apparatus, the apparatus is formed in the shape of a hollow domed housing within which a volume pulse sensor (30) is located, retained with resiliently adjustable bias force such that the sensing surface (33) of the volume pulse sensor extends just slightly above the outer surface of the domed housing. The spring force with which the sensor engages a finger (45) of the patient is adjustable by an externally adjustable disk or wheel (37).
