Disclosed is a clamp mechanism to assist in attaching a finger cuff to a patient's finger by a medical assistant. The clamp mechanism may comprise a mounting structure including a top portion having a gap, opposed descending sides, an exterior, and a pair of opposed clamping members. The pair of opposed clamping members extend from opposite sides of the exterior of the mounting structure to form a clamping slot over the gap. The clamping slot is openable by the medical assistant to allow for the pulling of the first side and the second side of the finger cuff by the medical assistant through the gap and the opened clamping slot. Further, the clamping slot is closeable by the medical assistant so that the first side and the second side of the finger cuff are clamped together such that the finger cuff is firmly attachable to the patient's finger.
