More Information
Summary:An access site disconnection system and method employ RFID sensors that are sensitive to moisture and their presence may not be detected if the sensor is wetted. When a patient receives dialysis treatment, wetness may arise from blood if the access needle becomes disconnected from the access site. At least one RFID sensor is mounted on or near gauze or other absorbent material placed adjacent the access site. After the sensors are placed, the dialysis machine and RFID control circuit may be initialized and dialysis treatment, such as hemodialysis, begun. If blood leaks from the access site, such as if the access needle is dislodged, the RFID sensor is wetted and sends a different or no response to periodic inquiries from an RFID reader. A signal is sent to a controller or to an output device to raise an alert or sound an alarm.
