DUAL FLOW BLOOD MONITORING SYSTEM
First Claim
1. A dual blood flow monitoring system comprising:
- an electronic first sensor for monitoring a first blood flow, the first sensor operative to generate a first signal conveying information regarding at least one parameter of the first blood flow;
an electronic second sensor for monitoring a second blood flow, the second sensor operative to generate a second signal conveying information regarding at least one parameter of the second blood flow; and
an electronic monitoring device in communication with the first sensor and the second sensor, the electronic monitoring device operative to receive the first and second signals, and to calculate and display a differential value representing a difference between the at least one parameter of the first blood flow and the at least one parameter of the second blood flow.

Abstract
A dual blood flow monitoring system includes an electronic first sensor, an electronic second sensor, and an electronic monitoring device in communication with the first sensor and the second sensor. The first sensor monitors a first blood flow and the second sensor monitors a second blood flow. The electronic monitoring device is operative to receive signals from the sensors and to calculate and display a differential value representing a difference between the at least one parameter of the first blood flow and the at least one parameter of the second blood flow. A dual blood flow monitoring system is provided in a method for simultaneously monitoring extracorporeal arterial and venous blood flows, in which the sensors are placed in communication with respective tubing lines carrying the arterial and venous blood flows.

13. A method for simultaneously monitoring extracorporeal arterial and venous blood flows, the method comprising:
-
providing arterial blood to a patient through a first tubing line; receiving venous blood from the patient through a second tubing line; providing a dual blood flow monitoring system that includes an electronic first sensor, an electronic second sensor, and an electronic monitoring device in communication with the first sensor and the second sensor, the electronic monitoring device having a display; maintaining the first sensor in communication with the first tubing line as the first sensor generates a first signal conveying information regarding the flow rate of the arterial blood; maintaining the second sensor in communication with the second tubing line as the second sensor generates a second signal conveying information regarding the flow rate of the venous blood; determining the flow rate of the arterial blood based on the first signal; determining the flow rate of the venous blood based on the second signal; calculating a differential value representing the difference between the flow rates of the arterial blood and the venous blood; and displaying the differential value on the display of the monitoring device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
