1. Thrust checks The thrust checks detailed below use the weights that correspond to the factory set occlusion threshold levels for a 3300 i e 4 5 and 5 5 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 9 1 Set the pump s plunger clamp to approximately mid way along its support tube 2 Remove the plunger from a spare BD 60 ml syringe Modify the syringe by sawing off the pointed end Place the modified syringe onto the pump so that it acts as a guide for the weight support rod see Figure 2 2 3 With the pump switched ON set the infusion rate to STAT 4 Place the pump in a vertical position with its left hand side uppermost see Figure 2 2 5 Place the weight support rod through the modified 60 ml syringe and onto the pump s plunger clamp 6 Place a weight of 4 5 kg on top of the weight support and check that the pump operates at least 30 seconds and does not occlude i e the alarm does not sound Remove the weight 7 Place a weight of 5 5 kg on top of the weight support and check that within 60 seconds the pump does occlude i e the alarm sounds i gt WEIGHTS WEIGHT SUPPORT lloa SYRINGE BODY BAI MODIFIED 4 SYRINGE BARREL CLAMP MID WAY POINT DES a L 7 7 SYRINGE SIZE SENSOR JH syringe PLUNGER CLA

5. 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 If no IV pole is used make sure that the pump is completely stable on a horizontal surface Failure to observe this warning may cause damage to the 3300 PCA pump and harm the operator or the patient As a result the operator or patient may suffer direct injury or the 3300 PCA pump may fail to operate correctly leading to patient injury or death 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 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 WARNING The patient history is lost when the clock is reset 3300 Service Manual Issue 7 August 2004 Page ix Cautions Cautions U S A and Canada FOR THE ATTENTION OF USA USERS Smiths Medical International Ltd Cautions tell you about dangerous conditions that can occur and cause damage to the pump if you do not obey all of the instructions in this manual 1 2 CAUTION Refer all service repair and calibrations only to qual

17. Smiths Medical International Ltd Patient control and sensing alarm systems Patient control system The Patient control system consists of a handset containing a button which when pressed generates a short pulse of air pressure slightly above atmospheric pressure This pulse travels down the attached flexible plastic system tube via a socket to a pressure sensing switch Thus there are no electrical connections to the Patient The operation of the sensing switch sends an interrupt request to the slave processor This initiates the PCA bolus request which is logged and the dose will be delivered if the request is valid Monitor interfaces The pin outs on the printer respiration Monitor interfaces are designed to be similar to the serial interface on an IBM PC Sensing alarm systems Introduction Syringe nearly empty End of infusion occlusion AC power failure Battery power low and OFF RECHARGE Self tests pump malfunction Drive disengaged or syringe not fitted In addition to the occlusion sensing system page 3 2 the following sensing systems are also operative within the pump A metal flag protrudes from the left hand side of the half nut in parallel with the leadscrew this is the nearly empty flag When this flag de activates OPTO 0 see page 4 25 situated at the left hand side of the leadscrew and the slotted disc is still rotating the processor makes a calculation that depends on the infusion rat
