Patent ID: 7618380

Claim:
A method of preventing nerve damage positional injury during surgery, comprising: putting a surgery patient under general anesthesia; providing at least one site sensor to detect pressure on at least one area of the patient prone to nerve damage positional injury during surgery, the at least one site sensor including a transducer in the form of a substantially circular cupped, convex transducer element and a substantially annular ring extending circumferentially outward from the transducer element; adhering the ring of the at least one site sensor to the patient circumferentially around the at least one area of the patient prone to nerve damage positional injury during surgery so that the substantially circular cupped, convex transducer element forms a protective convex baffler in front of, and does not contact, the at least one area of the patient prone to nerve damage positional injury during surgery, the at least one area of the patient prone to nerve damage positional injury during surgery disposed underneath the transducer without contacting the transducer, the ring is adhered without contacting the at least one area of the patient prone to nerve damage positional injury during surgery; connecting the at least one site sensor to a monitor to monitor pressure on the at least one area of the patient prone to nerve damage positional injury during surgery with the at least one site sensor; continuously monitoring pressure on the protective convex barrier formed by the substantially circular cupped, convex transducer element in front of the at least one area of the patient prone to nerve damage positional injury during surgery with the at least one site sensor and monitor; alerting medical personnel of the pressure condition on the protective convex barrier formed by the substantially circular cupped, convex transducer element in front of the at least one area of the patient prone to nerve damage positional injury during surgery if the monitor and site sensor determine a pressure condition exists on the protective convex barrier formed by the substantially circular cupped, convex transducer element in front of the at least one area of the patient prone to nerve damage positional injury during surgery; readjusting the patient's position to alleviate the pressure condition, preventing nerve damage positional injury positional injury during surgery.
