USB Sensor

A plethysmograph sensor that attaches to a plethysmograph instrument, used to measure volume changes in a limb or digit. The sensor has a tube filled with electrically resistive fluid (indium-gallium), and is wrapped around the circumference of the limb or digit. The plethysmograph instrument measures the resistance changes of the sensor that occur when the resistive fluid column length changes according to circumference changes that occur with vascular flow changes.

A plethysmograph sensor that attaches to a plethysmograph instrument, used to measure volume changes in a limb or digit. The sensor has a tube filled with electrically resistive fluid (mercury), and is wrapped around the circumference of the limb or digit. The plethysmograph instrument measures the resistance changes of the sensor that occur when the resistive fluid column length changes according to circumference changes that occur with vascular flow changes.

The Radink Sensor uses a combination of a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer to locate a patient's body in 3D space. It is calibrated to the patient's original position immediately prior to the surgery so any movement is tracked and the patient can be returned to the original position at any time during or after the surgery.
