NB-BVP-F (finger module):The BVP sensor provides a photoplethysmography (PPG) signal when connected to a NeXus signal acquisition device, that corresponds with variations in peripheral blood flow resulting from cardiovascular activity and responses, with the purpose of providing information on the cardiovascular variations such as heart rate variations and measured pulse amplitude. The sensor output is not intended to be used for vital monitoring purposes.The device is designed for medical use, not restricted to a specific medical indication, for acquisition of physiological signals. The device is intended to be used by, or under supervision of, a health professional within a clinical environment.
A photoelectric device designed to be applied externally to a portion of a limb (e.g., a fingertip, toe) for the transcutaneous measurement of blood volume using light detection during limb plethysmography. It is intended to be connected to a limb plethysmograph (not included), whereby volume changes are represented graphically to represent blood flow/pulse. It is designed for use during vascular function assessment in a limb (e.g., measurement of toe brachial pressure index). Although similar to a pulse oximeter probe, it is dedicated to limb plethysmography, and not capable of oxygen saturation measurements. This is a reusable device.
