Warnings and cautions Introduction
This Technical Service Manual together with the Instruction Manual, contains all the information that is needed to maintain, repair and operate the Graseby 3150 pump. The contents of this Manual are intended to be read and used by suitably qualified personnel.
AC input power connecting socket/ cable The AC input power socket that connects to the rear of the pump has three connections (live, neutral and earth) provided by a 3-way power cable. As the casing is doubly insulated, the AC input connector situated on the pump only utilises two connections (live and neutral), there is no third earth pin. This method of AC input enables similar AC input sockets (if required) to that supplied by Smiths Medical to be used.
Warnings and cautions Warnings tell you about dangerous conditions that could lead to death or serious injury to the user or patient that can occur if you do not obey all of the instructions in this manual. WARNINGS 1. WARNING: To avoid over- or under- infusion, always verify that the brand and size of the loaded syringe are the same as the brand and size displayed on the screen before starting an infusion. Failure to do so may result in an inaccurate delivery of medication, resulting in patient injury or death. 2. WARNING: To avoid incorrect or inappropriate configuration of the pump, the Configuration menu must only be selected by qualified persons or authorised personnel. Incorrect pump configuration could lead to inappropriate infusion resulting in patient injury or death. 3. WARNING: This equipment is not suitable for use in the presence of flammable anaesthetics, oxygen-enriched or explosive atmospheres. The use of the device in such atmospheres may lead to explosion or fire. 4. WARNING: To avoid possible malfunction of the pump, do not expose the pump to X- rays, gamma rays or ionizing radiation, or to the RF interference or strong electric/magnetic fields emitted (for example) by diathermy equipment or mobile telephones. If the pump is used in the presence of, or in combination with Magnetic Resonance Imaging (MRI) machines it must be protected from the magnetic field emitted by such equipment. Malfunction of the pump can cause incorrect infusion or loss of infusion resulting in patient injury or death. 5. WARNING: Operation of the pump outside the temperature limits defined in the specification may result in erroneous operation. Ensure that the temperature is within the specified limits. Failure to do so may result in patient injury or user injury. 6. WARNING: In order to ensure that the intended infusion is performed, data must be entered correctly. Likewise before confirming any displayed data the user should ensure that it is correct. Failure to do so may result in compromised function of the product, patient injury or user injury. 7. WARNING: Failure to respond promptly to an alarm may result in patient injury or death. 8. WARNING: Failure to follow the Service Manual’s maintenance schedule recommendations may result in compromised function of the product and lead to patient injury or death. 9. WARNING: It is essential that clinical staff remain within visual and audible range of the pump so that critical alarms can be seen or heard and responded to. 10. WARNING: The user should ensure that the performance offered by the pump is fit for the intended purpose. Failure to do so may result in compromised function of the product, patient injury or user injury. 11. WARNING: When the pump is carrying out an infusion, to ensure that electrical safety is maintained only items of equipment that conform to EN60950 are to be connected to the RS232 connector situated at the base of the pump, otherwise patient safety may be compromised. 12. WARNING: Correct management of battery charging is essential to ensure that the pump can operate on batteries for the time specified. Failure to do so may lead to impaired functioning of the pump, resulting in patient injury or death. 13. WARNING: Do not use a faulty pump. If the pump develops a fault then an alarm will sound; the display will indicate a FAULT condition and the pump will fail to infuse. Incorrect performance of the pump can cause complications resulting in patient injury or death. If the pump develops a fault then it must be referred to a suitably qualified engineer or returned to Smiths Medical in order to have the fault rectified. 14. WARNING: Failure to use the mains lead clamp means that the pump may be accidentally or erroneously disconnected from the mains. Although there is battery backup in case this happens, the battery may not be sufficiently charged. Consequently there is a risk of the pump not functioning, which could lead to patient injury or death. 15. WARNING: If an occlusion alarm occurs, immediately clamp the line to eliminate the possibility of a bolus being delivered to the patient. Then inspect the fluid pathway for kinks, clogged catheter, etc. in order to remove the occlusion prior to restarting the infusion. An unintentional bolus of medication can result in patient injury or death.

Warnings and cautions
Smiths Medical International Ltd.
16. WARNING: Use only the syringes and administration sets listed in the Specification (Chapter 1). Failure to do so may result in an inaccurate delivery. Smiths Medical does not guarantee performance of the pump if syringes other than those listed are used. Incorrect function or performance of the pump can cause complications resulting in patient injury or death. 17. WARNING: The volume of fluid contained in the connecting tubing is a residual amount and will not be infused. Hence this extra volume of fluid must be allowed for when initially filling the syringe and purging the system. Under-delivery of medication can cause complications resulting in patient injury or death. 18. WARNING: To avoid patient embolism, ensure that the patient tubing is purged of all air bubbles before administering any medication. The pump provides a purge facility to assist with this process. The presence of air within the medication can result in complications leading to patient injury or death. 19. WARNING: To avoid syphoning of the syringe contents (free flow), ensure that the syringe is correctly loaded into the pump, that the syringe plunger is properly engaged by the pump’s actuator and that the pump is placed not more than 80cm above the infusion site. Syphoning can result in over-infusion leading to patient injury or death. 20. WARNING: To avoid over-infusion, do not purge the infusion line when the administration set is connected to the patient. Over-infusion of medication can result in patient injury or death. 21. WARNING: To avoid the pump becoming detached from an IV pole always make sure that the pump is securely fixed to the pole. Always check the security and stability of the assembly with the pump mounted. 22. WARNING: Following a significant liquid spill onto the pump, it should be wiped dry and inspected by service personnel before being returned to service. Failure to do so may result in compromised functioning of the pump, leading to patient or user injury or death. 23. WARNING: When using a syringe smaller than 50/60 ml the occlusion pressure will increase as the diameter of the syringe decreases, i.e. the smaller the syringe the higher the pressure. 24. WARNING: The patient history is lost when the clock is reset. 25. WARNING: Only adequately qualified personnel should maintain and repair the pump. 26. WARNING: The pump must be disconnected from the AC power supply before the case is opened. 27. WARNING: The Configuration and Diagnostic mode must only be used by personnel who are adequately qualified and have previous training in the use of the pump. 28. WARNING: The safety and reliability of the pump may be compromised by the use of parts other than those specified in this Manual. 29. WARNING: When a new Syringe Size Sensor Flag has been fitted to the pump (see Appendix), then the pump must be tested using the new syringe size sensor gauges available from Smiths Medical (part number 0131-0202). Page 3 of the Appendix gives details of the Final Testing procedures. 30. WARNING: The pump must be set to display the brand and the size of syringe that is going to be used. Using a different brand or size of syringe to that being displayed could lead to the incorrect amount of drug being administered, that could result in injury or death. 31. WARNING: The internal pump batteries must be disposed of in accordance with the manufacturers instructions. Lead acid batteries must NOT be placed in the normal waste stream.

CHAPTER 1 INTRODUCTION, FEATURES, CLASSIFICATION and SPECIFICATION
Graseby 3400 Anæsthesia Syringe Pump
Smiths Medical International Ltd.
Introduction
CHAPTER 1 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 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. The infusion entails presetting into the pump both the required infusion rate and the dose of the drug that is going to be used. The pump can be configured by a suitably qualified person to work with any one of several selected brands of syringe, plus, when converted, the Braun Perfusor syringe. The particular brand of syringe selected will be displayed. The diameter of the syringe installed is automatically sensed by the pump and from this dimension and knowing the syringe brand the pump is able to calculate and display the following syringe sizes: 5; 10; 20; 30 and 60 millilitres. The pump is a compact robust unit that is able to function either sitting on a table top or mounted on an IV pole via the pump's pole clamp.
General information
The pump can be configured to: •
deliver a volume or mass unit, manual controlled infusion, or
•
a volume or mass unit bolus infusion.
A running total of the volume of liquid that has been infused is stored in the pump’s totaliser, and will remain available for display even though the infusion may have been stopped and then restarted. The totaliser can be set to zero when required. The pump can be operated from AC power or from internal rechargeable batteries. When functioning on fully charged batteries, and under normal conditions, the pump gives more than ten hours of continual use. The AC power can vary between 100 V and 250 V and 50 to 60 Hz, thus allowing the pump to be used anywhere in the world without adjustment. A battery charging circuit within the pump keeps the batteries charged. The batteries are fully charged when the AC power has been connected to the pump for 14 hours, even though the pump itself may be switched off. Numerous safety features have been built into both the software and the hardware, and the user is warned of such incidents as a power failure or an occlusion by both visible and audible alarms. The pump carries out a self-testing routine each time it is switched on. Security cover
An optional security cover kit is available (part number 0131-0277). The kit includes all the items required to modify the pump, including comprehensive fitting instructions. When fitted, the kit protects the syringe from tampering only; it provides no other security. It does not lockout the keypad or give audible or visual alarms when opened.
