ELECTROMAGNETIC INDUCTION ACCESS DISCONNECT SYSTEMS
First Claim
1. An access disconnect system comprising:
- blood tubing including a blood filter and an arterial tubing side of the blood filter;
a blood processing machine including a blood pump operable with the blood tubing;
first and second conductive contacts located in the blood tubing on the arterial tubing side of the blood filter, the first conductive contact located upstream of the blood pump, and the second conductive contact located downstream of the blood pump, the first and second conductive contacts positioned and arranged to form a conductive circuit including a vascular system of a patient and the blood processing machine;
a source of electric current connected to at least one of the first and second conductive contacts; and
a transmitter for sending a signal indicative of an amount of current flowing through the conductive circuit when the source of electric current is applied.

Abstract
An access disconnect system includes a blood processing machine having a blood pump operable with blood tubing, first and second conductive contacts located in the blood tubing on an arterial tubing side of a blood filter. The first conductive contact is located upstream of the blood pump and the second conductive contact is located downstream of the blood pump. The first and second conductive contacts are positioned and arranged to form a conductive circuit including a vascular system of a patient and the blood processing machine. The system further includes a source of electric current connected to at least one of the first and second conductive contacts and a transmitter for sending a signal indicative of an amount of current flowing through the conductive circuit when the source of electric current is applied.
