    Occlusion system Smiths Medical International Ltd. Plunger clamp When the plunger clamp is pulled down, the half nut/super nut engages with the leadscrew and the clamp engages with the end of the syringe. The syringe plunger slots into place behind a slotted pair of lips. These lips prevent the syringe plunger from moving forward in the event of negative pressure on the syringe.

  • Page 40: Electro/Mech Control System

    Smiths Medical International Ltd. Electro/mech control system The above action causes a voltage proportional to the pressure in the infusion line to be input to one of the channels of the 8 bit A-to-D converter in the micro-controller. If the output from the A-to-D converter exceeds the predetermined value set by the user, an in-line occlusion alarm is generated.

  • Page 41: Battery Voltage Low

    Sensing (alarm) systems Smiths Medical International Ltd. Battery voltage The sensing circuits incorporate a system that monitors the output of the batteries and registers an alarm if the voltage of the batteries drops below 5.75 V.

  • Page 112: Fitting A Modified Size Sensor Flag

    In a continual and ongoing programme of improvements to their 3000 range of syringe pumps, Smiths Medical engineers have introduced a modified Syringe Size Flag (SSF) 1 that allows the size sensor mechanism to be accurately aligned (see Figure A) .

  • Page 113: Opening The Case

    When a new SSF has been fitted to a pump, the pump must be tested using the Syringe Size Sensor gauges ( part number 0131- 0202 ) available from Smiths Medical. Page A-3 gives details of the Final Testing procedures.

  • Page 114: Reassembly

    The shim sizes provided in the kit are 0.6, 1.0, 1.2 and 1.4 mm. If necessary, use a combination of shims to obtain the thickness required, up to a maximum of 2.4 mm. During production at Smiths Medical, a 1.6 mm shim is initially fitted to the pump.
