  • Page 14: Introduction

    INTRODUCTION, FEATURES, CLASSIFICATION AND SPECIFICATION Introduction The 3400 anaesthesia syringe pump (Fig. 1.1) is based on a micro-controller design and has been purpose developed by Graseby for the administration of anaesthetics, mainly in a hospital operating theatre. The pump allows a Manually Controlled Infusion, and/or a bolus to be infused using the normal brands of syringe.

    Nearly Empty alarm; etc., • designed in consultation with users. Classification The following classification information applies to the 3400, and is to the IEC 601-1:1988 requirement. Insulation The pump is a Class II (double insulated) device. Also classified as internally powered equipment.
  • Page 17: Specification

    Specification SIMS Graseby Ltd. Graseby pumps are subject to continual development and the 3400 may, therefore, differ Specification slightly from the following specification: Dimensions: 325 mm (long) x 195 mm (high) x 115 mm (deep) with the pole clamp fitted and the plunger clamp closed.
  • Page 18: Brief History Of Graseby Bedside Syringe Pumps

    A larger liquid crystal display was used on the 3400 with the ability to display text in different sizes, also ‘soft-keys’ were used to make the user interface simpler. The range of syringe sizes that could be used was also increased. For more advanced applications the pump could be controlled by a computer.
  • Page 19 A large text vacuum fluorescent display was added, and the increased syringe size range of the 3400 remained. A DC input supply (10 V to 28 V DC) version of the 3200 is also manufactured by SIMS Graseby. This variant is primarily intended for use in an aviation environment.

  • Page 21: Configuration & Diagnostic Mode, And Thrust Adjustments

    WARNING The Configuration Mode must only be used by personnel who have been appropriately trained in using the 3400. The Configuration mode allows various parameters to be made available, which in turn allows various settings within these parameters to be set to the values required for the infusion.

  • Page 26: Occlusion Measurements

    The thrust of a particular pump may, therefore, differ from the original factory set level. The occlusion thrust of the 3400 pump is factory set at Graseby’s to be between 5.7 kg and 6.2 kg (767 mmHg and 834 mmHg).
  • Page 27: Thrust Checks

    The thrust checks that are detailed below use the weights that correspond to the factory set Thrust checks occlusion threshold levels for a 3400 (i.e. 5.7 and 6.2 kg). If a different occlusion level setting is required then the weights will have to be adjusted accordingly. The thrust adjustment procedures are detailed on page 2-8.
  • Page 28: Thrust Adjustments

    In order to obtain the thrust required it may be necessary to repeat steps 2 to 7 above. Finalise the assembly of the pump casing (see page 2-5). 10. Carry out tests No 9 and 10 detailed in the functional test procedures (see page 6-3). 2 — 8 Issue 6 (July 00) 3400 Service Manual...
