8. Drive The pump s drive system is designed so that it is only engaged when the top of the syringe disengaged or is correctly positioned in the plunger clamp syringe not fitted If the plunger clamp is displaced during an infusion the drive automatically stops due to the disengagement of the half nut The disengagement of the half nut is detected by an opto sensor If the pump tries to operate without a syringe or with a syringe incorrectly fitted the pump goes into an alarm state Syringe sizing syringe sizing system comprises a flag moulding assembly Figure 7 2 that rests on the system barrel of the syringe In conjunction with three size sensors Figure 7 6 it measures the diameter of the syringe being used The flag moulding rotates about the outer of the two guiding tubes and moves an actuating flag between the three size sensors The flag is able to de activate the three size sensors in any one of the following combinations none 1 1 2 1 2 3 2 3 or 3 Depending on the operation of the size sensors the pump monitors the size of a syringe as being 5 10 ml 20 ml 30 ml or 50 60 ml Alternatively if a syringe is not fitted onto the pump or a syringe smaller than 5 ml is fitted then the SYRINGE INVALID alarm is activated Rate setting For each size of syringe there is a maximum rate at which the pump is able to infuse The syringe size maximum rate can be constrained to an absolute maximum rat
