11. 1 8 DYNAMIC MONITORING SYSTEM DMS The following is general information regarding the Dynamic Monitoring System In order for fluid to move through the administration set a pressure difference gradient must exist In a gravity setup this is done by head height In a pump the instrument will develop pressure to overcome downstream effects on fluid flow The fundamental concept behind the Dynamic Monitoring System is that the resistance to fluid flow from the mechanism to the patient s infusion site can be measured This is done by intentionally varying the flow rate while monitoring the resulting changes in fluid pressure refer to Figure 1 3 Resistance Graph Signal processing of the pressure and flow data can then produce the fluid impedance value Such measurements can be made continuously at short intervals and be independent of the selected rate Head height and resulting pressure variations likewise will not affect the measurement When a complete occlusion occurs the resistive part of the fluid impedance is very large theoretically infinite Elevated resistances due to clotting clogged filters partial occlusions or infiltrations can be measured The Dynamic Monitoring System provides a means to measure the mechanical properties of the downstream flow path Figure 1 3 Resistance Graph 2 D RATE HI o ul ig SET RATE gt o0 W nA RATE LOW o F F Nominal FLOW cause

The Air in Line AIL Detector System consists of Transmitter arm that also loads set in position to monitor for air Receiver which is mounted in mechanism Voltage control oscillator VCO COMBO IC and associated circuits The voltage control oscillator will sweep a frequency range of 1 to 4 MHz and serve as the excitation for the ultrasonic AIL transducer This frequency sweep is necessary to ensure that the piezoceramic elements will achieve resonance over assembly and temperature variances The AIL Gate signal will initiate the VCO to sweep The detector is scanned at a 10 msec rate 40 msec to check bubble and once a second to test the AIL hardware On the receiver side the signal envelop will be seen if fluid is in the set This signal is AIL TEST COMBO IC Digital Output 1 4 MHz AIL DRVP A B Swept Voltage Controlled AIL DRVN A B Oscillator COMBO IC PRES TST A B Pressure igi Transducer Digital Output Assembly Air in Line Detector Block Diagram then returned to the COMBO IC and eventually to the processor to determine if air is present no signal and to compute the size of the air bubble With accumulator on the instrument will consider air bubbles separated by less than 70 microliters of fluid as one bubble and alarm accordingly The instrument will also alarm if 10 to 15 of downstream tubing is filled with air varies with alarm set point 4 6 3 Transducer refer to Fig
