First Claim
Patent Images
1. A method of detecting blood leakage, the method comprising:
- providing a glucose detector;
mounting the detector adjacent an extracorporeal blood processing access site;
taking a baseline reading from the detector on the access site on a patient;
processing the baseline reading and determining a baseline;
monitoring the detector for indications of blood leakage; and
sending a signal if blood is detected.

Abstract
An access disconnect sensor for a patient undergoing extracorporeal blood processing includes an electrochemical fuel cell or sensor to detect blood leakage. The fuel cell includes circuitry for oxidizing glucose in the blood. The sensor also includes a transmitter to send a signal to a remote receiver that the sensor indicates the presence of blood. The circuitry may include a battery or may use electricity generated by the sensor to send a signal indicating a leak of blood or disconnection of the access needle.
