ABSTRACT:
To provide for adjusted positioning of a pulse sensor (50) against the selected toe of a patient, while the patient is relaxed, and without applying substantial pressure of the sensor against the toe, a base plate is formed with a depression to receive the heel of the foot of the user, and a support element (20) is adjustably positioned on a pair of parallel vertically extending posts (17, 18), projecting from the base plate. The support element is a transverse structure, slidable on the posts, and having a shaft (30) to which a bail (42) is attached. The pulse sensor (50) is mounted on the horizontal portion (48) of the bail, and is slidable along and rotatable about the portion (48). In addition, the bail (42) is slidable sideways (B) with respect to the foot of the user, i.e. across the toes, movable back and forth with respect to the toe to be tested while the pulse sensor (50) is retained against the toe by a spring (34) biasing the shaft, and hence the bail, towards the toe. This permits movement of the pulse sensor in three dimensions as well as tilting and rotating the pulse sensor with respect to the toe (61).
