  • Page 14: Chapter 2 - Theory Of Operation

    THEORY OF OPERATION Chapter 2 2.1 MECHANICAL 2.1.1 Mechanical Drive Assembly 2.1.1.1 Overview The Mechanical Drive Assembly provides several operational functions for the pump. In operation, this assembly: 1. Secures the syringe plunger and linearly pushes the plunger into the syringe barrel; 2.
  • Page 15 Chapter 2 THEORY OF OPERATION Bearing is press fitted to the Force Plate/Insert Assembly to accommodate the other end of the Leadscrew. A Shaft is attached to the Motor Plate Assembly and to the Force Plate/Insert Assembly using two screws. This shaft guides the Plunger Driver back and forth in its range of travel while helping to keep the Plunger Driver Assembly from rotating perpendicularly in relation to the direction of infusion travel.
  • Page 16 THEORY OF OPERATION Chapter 2 • Syringe is Present Mode When the syringe plunger is properly installed in the Mechanical Drive Assembly, the Lever Pin is in the straight portion of the slot on the Slide, the Drive Potentiometer will be activated by the middle spring of the Wiper Spring, and the pump will properly detect the presence of the syringe plunger.

  • Page 17: Barrel Clamp Assembly

    Chapter 2 THEORY OF OPERATION • Lower Plunger Assembly The Plunger Driver Lever rotates in the Plunger Driver Carriage on two Lever Screws that have precise diameters. The Lever Screws act as hubs for the Lever and secure the Lever to the Carriage.

  • Page 18: Pole Clamp Assembly

    THEORY OF OPERATION Chapter 2 The syringe barrel flange is held against the cradle by the tablock bracket. The tablock bracket is raised or lowered by the rotation of the pendulum. One end of the pendulum rides in a slot in the barrel clamp slide. The other end of the pendulum raises the tablock bracket.

  • Page 19: Pole Loop

    Chapter 2 THEORY OF OPERATION The main function of the pole clamp is to attach the pump securely to an IV pole. The pole clamp mounts onto the back of the pump and is held in place by tightening a small thumbscrew.

  • Page 21: Syringe Barrel Clamp

    Chapter 2 THEORY OF OPERATION mechanism that lifts the wiper on the plunger drive potentiometer if the plunger is not properly captured, this open circuits the potentiometer. The syringe size is determined by a linkage between the barrel clamp and a potentiometer that enables the pump to determine the size of the syringe installed.

  • Page 22: Syringe Plunger Position And Capture Detector

    THEORY OF OPERATION Chapter 2 2.2.3.3 Barrel Position Detector Barrel position detection is provided by two membrane switches connected in series in the barrel clamp assembly. Each switch is activated by pressure of the syringe barrel on its respective half of the barrel cradle. Both switches must be activated to bring “BARREL*” low.

  • Page 23: Battery Pack

    Chapter 2 THEORY OF OPERATION 2.2.8 Battery Pack The battery pack of the pump is a 5 cell 1.5 amp hour Nickel Metal Hydride pack. This gives it a nominal 6 volt operating voltage. Actual battery voltages range from a high of 7.4 volts to 6.1 volts at the low battery threshold.

  • Page 24: I/O Board

    THEORY OF OPERATION Chapter 2 2.2.10 I/O Board The I/O board contains the interface to external electronics for the pump.

  • Page 32 THEORY OF OPERATION Chapter 2 1. Plunger Driver Position Calibration This is accomplished by using calibration standards to input two drive position locations to the pump. The software then utilizes these two reference locations to complete the driver position calibration. With this information, the pump is then able to determine the distance between the plunger driver and the barrel clamp.

    Chapter 10 ALERTS AND ALARMS A CONFIG CORRUPT alarm condition requires one of two remedies: replication of a complete valid configuration from another pump, or downloading a configuration via the DB9 port. If the key sequence 9,8,0,5 is pressed in response to a CONFIG CORRUPT alarm following the POST, the pump assumes that the operator wishes to perform a replication.
