| 20110313394 | Sensor Controlled Flow Path For Providing Fluids To Patients - An outflow line is connected to an infusion pump that is programmed to run at a fixed rate. The outflow line has a bypass line that leads from the pump outlet back to the pump inlet. A line downstream of the entrance to the bypass line leads to the patient. The system has two valves. The fluid en route to the patient passes through the first valve. The bypass line passes through the second valve. When one valve is open, the other is closed. The valves' flow states are controlled by a signal from a control instrument. The system allows the pump output to be directed to the patient or to a bypass circuit that returns fluid leaving the pump back to the pump inlet. The system makes it possible to vary the amount of fluid delivered to a patient by an infusion pump set at a constant pumping rate by varying the open and closed state of valves in response to a signal from a patient monitoring instrument. | 12-22-2011 |
