3. OperationAn illustration of the front panel of the Volumed µVP5000 together with a fullexplanation of reference numbers is to be found at the beginning of this manual.

Caution: Use only Arcomed IV administration sets or equivalent(20 drops/ml, Silicone-insert: type 3/4mm, length 135mm, Shore-hardness Shore A,60)

The performance data depend on the IV-line / pump system. The use of a IV-linehas to be in accordance with the technical adjustment of the pump.

If other IV administration sets are used, the operating safety of the pump can nolonger be guaranteed. Patient safety may, as a result, be compromised.In accordance with the norm IEC 60601-2-24, the IV-set should be replaced every24 hours. The IV-sets are for single use only (BS 5724).

3.1. Preparation / Insertion of the IV-seta) If the unit is mounted on a floor stand, care must be taken to ensure that it is fixed

at a height not exceeding 1.2 m above floor level, in order to ensure stability. Theunit can also be placed on a flat surface.

b) With the aid of the knurled screw (1) on the back of the unit, the bottle/containerholder (2) can be adjusted so that the drip chamber (3) is held firm by slotting itinto the empty bag detector (4). Make sure that there are no large ribs or joints inthe passage of the empty bag detector and that fallen drops are detected by theempty bag-detector‘s light-barrier.

c) Carefully purge the infusion set, without allowing any air bubbles to enter, untilthe drip chamber (3) is 1/4 to 1/3 full. If air has entered, repeat purge-procedure.

d) Close the tubing roller clamp.

e) Open the pump chamber door (5) by raising the door latch (6).

f) Press back the red handled „stop-flow“ lever (7) until it is inside the recess.

g) Starting with the left side, insert the silicone section of the IV set into the tubeguides (8) so that it is slightly tensioned. Ensure that the flow direction of thepump from the left to the right is respected. Insert the tubing carefully in the airdetector (9) from top to bottom in the direction of the arrow. Ensure there is a loopbetween the pump door outlet and the air detector.

h) Close pump door (5).

i) Open tubing roller clamp. Check that there is no „free-flow“.Plug the power supply cable into the back of the pump and connect it to an ACpower supply outlet unless battery operation is required. The AC operationpower indicator (15) will light up and battery charging will commence. If not,check power cable and both fuses (24).

Note: The power supply must include a reliable earth connection for safety. Anearth terminal is provided on the back of the unit (25) for connection to anindependent protective earth system if necessary. If the integrity of the protectiveearth system is in doubt, always operate the pump from its internal batterysupply.

k) Press ON/OFF key ( ) (17). The audible alarm beeps once together withthe indication < ! > in the alarm window (16). The software version number(µVP5000, rx.xx) and the configuration of the pump (µVP5000, c.xxx) light upbriefly.

Page 5

3.2. Rate (ML/H)

Set the desired rate with the Up/Down keys (11) in the rate display(10). Keys witharrow up increase the rate, those with arrow down decrease the rate in single steps.

3.3. Total volume (TOTAL ML)

After setting the rate, use the Up/Down keys (13) in the total ml display (12) to setthe total volume to be infused. When the Volumed® µVP-5000 reaches the presettotal volume the pump goes into infusion complete (indication window), gives anaudible alarm and the rate will be switched to the KVO rate.If no total volume is desired, the pump can be started directly after setting the rate.

3.4. Alternative operationIf you want to use one of the following variants, please contact our CustomerService Department or contact the approved ARCOMED distributor for your country(see also point 1.1).

a) Reset the Ml InfusedReset of the Ml Infused after every Start/Stop.

b) SBS (Step by step) or titrationIf the volume is increased after reaching the preset total volume, only thedifference between the new and old values is infused when the pump isrestarted. Volume infused can be either accumulated or not.

c) Storage of the last set ml/h rate and total ml.

d) Display of time infused and or drops infused.

e) Adjustment of the audible alarm volume level.

3.5. Accessories and consumablesAccessories, expendable parts and single-use items may only be used if theycomply with the appropriate international standard and national approvals.Syringes, filters and extension sets must be CE marked.

The Instructions for Use and the mains power supply cable are included asstandard equipment with the Volumed µVP5000.

3.6. START/STOPOnce the rate is set, the pump can be started with the START/STOP key (18). Atevery fallen drop the drop lamp in the indication window (15) lights up.

3.7. Infused display (ML INFUSED)In the Ml Infused display (14) the actual volume is indicated. This indication is notinfluenced by starting/stopping the pump, however it is reset after the total volume isreached and the pump is restarted again. Also turning off/on the pump resets thevolume infused.

3.8. Alarm tone-mute key

The audible alarm can be suppressed for 2 minutes by using the alarm tone-mutekey (19). After two minutes the audible alarm will automatically restart if the pump isstill in alarm condition.

Page 6

3.9. ON/OFF ( ) -KeyTo turn On/Off the pump the ON/Off key (17) is used. This resets the rate ml/h, totalml and infused ml values to zero. The ON/OFF key has to be held down for morethan 1 second to turn off the pump. This prevents the pump from being turned offaccidentally.This switch is not a mains isolating switch, and the battery charging circuit is alwaysconnected to the mains (stand-by).

3.10. IV container exchangeWhen changing the plastic container or bottle, infusion can be interrupted at anytime by means of the 'Start/Stop' key (18) without affecting the set or displayedvalues. In this state, handling operations such as changing the container or IV setand rate changes can be implemented without activating the alarm. In the stopmode, 'KVO' operation is automatically activated.If the pump remains in the stop mode for more than 4 minutes, the audible reminderalarm will sound.

3.11. Keep-Vein-Open (KVO)In certain conditions the Volumed® µVP5000 automatically switches to the KVO-rate (Keep-Vein-Open rate). The KVO-rate is set to 3 ml/h (0.3ml/h Micro Pumpmode). However, if the rate set by the user is lower than 3 ml/h, the KVO-rate isequal to this rate.

3.12. Use in parallel or multiple infusionsIf several pumps are linked together for multiple or parallel infusions, infusion of air,reverse infusion or deviation of the flow rate might occur. If in doubt, please refer tothe matrix in the VDE 0753 part 5 or equivalent specifications for the correct set-upof your system.

3.13. Use of Disposable IV administration setsAlternatives to our recommended 8101P/LP sets can only be used, if their use is notin discrepancy with the security of the system and if the equipment has beencertified by a qualified laboratory or institute.

3.14. External interconnectionsWhen interfacing via the connector (22) and (24), only equipment can be usedwhich meets the specifications of the IEC 60601-1-1:1992 or when it has beenproved by a certified body that there is no influence on the safety of the system.- Use only the external drop- detector Nr. 98502 (24)- Use the cable 94070 for the nurse call (23)- For the RS 232C (optional 20mA passive interface), please contact our Servicedepartment (see 1.1).

3.15. Environment

Used IV set are dangerous and must be discharged according to the localregulations. Used batteries must be recycled or returned to the supplier. A list of theused materials can be obtained form our service department.

4. Alarm supervision system

4.1. Alarm causes

During the operation of the unit, the built-in supervision system continually checksthat the pump is operating correctly. In the event of a malfunction, the infusion isimmediately suspended and the alarm is activated. This is signaled by the lightingup of the 'ALARM' display (15) with the corresponding alarm symbols continuouslyilluminated in red and by an intermittent audible alarm. At the same time, the nursecall system will be activated. If there is no 'Occlusion' or 'Air alarm', the KVO rate isactivated.

The Volumed® µVP5000 cannot be started:

- if the infusion tubing is not inserted or is incorrectly inserted in the air detector (4).- if the rate is not set (0 ml/h).- if there is an occlusion or the door is open (alarm through optional pressure

sensor).

During operation, the Volumed 5000 switches on the audible alarm and 'KVO'operation if:

- handling operations are performed on the rate or total input keys (11 and 13)- the Start/Stop (18) key is actuated- the infused quantity has reached the preset total volume value. During operation

the Volumed® µVP 5000 emits an audible alarm and goes into the 'Stop' mode if:

- a deficit/excess total number of mls are detected in relation to the ml/h rate- the liquid level in the drip chamber is too high- the tubing roller clamp has not been opened- the infusion bottle or plastic container is empty- the charge state of the battery can no longer guarantee continuous infusion- the pressure in the tubing exceeds the maximum permissible value- the infusion tubing contains air bubbles- the infusion PVC tubing is not fitted correctly in the air detector- the door is open.

4.2. Cancelling the alarm condition

After rectifying the cause of the alarm or acknowledging the rate change, the alarmcondition is cancelled and infusion resumed by pressing the START/STOP - key(18).

4.3. Air bubble detection

The µVP5000 goes in the following cases in air in line alarm:a) If there is a total of 500µl of air within 15 minutes. Induvidual small air bubbles

(>50µl) will be integrated during a time window of 15 minutes.b) If there is an air bubble greater than 50 - 250µl adjustable.

The air bubble alarm will light up and the audible alarm starts. If the air in line hasbeen solved, the air bubble alarm blinks and the pump can be started.

Page 8

4.4. Battery Alarm

The built-in battery enables the Volumed® µVP5000 to be used independently of amains supply. In the event of a mains failure, the pump automatically passes intobattery operation, without interrupting the infusion. If the battery is completelydischarged, the pump goes into battery alert. The battery alarm symbol in the alarmwindow lights up and an intermittent audible alarm starts. However, the pump runsnormally for at least 3 minutes before stopping. If the mains supply is connected inthe meantime, the alarm is automatically cleared.The Volumed® µVP5000 can also be programmed as to have a prealarm about 30minutes before being stopped, which is indicated when the green battery symbol isflashing. In this mode the battery also starts flashing when the mains supply isdisconnected. In both cases the audible alarm can be muted by pressing the alarmtone-mute key (19).Charging the battery takes about 20 hours while the pump is in operation, 15 hoursif the pump is turned off.

4.5. Nurse call alarmThe unit can be connected to an external call system by means of the connectionsocket (22) on the rear of the unit. For each alarm, the nurse call is thus transferredto the call station. This does not affect either the optical alarm display of the pumpor the audible alarm system.

4.6. Alarm tone-mute switchBy pressing the alarm tone-mute key (19) the audible alarm can be muted for aperiod of 2 minutes. After the muting time has elapsed, the alarm again sounds untilthe cause has been eliminated.

4.7. Alarm indications and their meaningIn order to be able to determine quickly the cause of the alarm, the alarm situationsare indicated by illuminated pictograms in the alarm window (16):

4.9. Technical description

The microprocessor controlled peristaltic pump Volumed® µVP5000 is suppliedwith a step motor drive and comprehensive software monitoring. The operatingrange of the pump allows rates from 0.1-999 ml/h to be selected. An integrated,rechargeable battery permits mains-independent operation for emergencies or forambulatory use.A mechanical stop flow is installed behind the door to prevent the infusion solutionfrom flowing freely in the event of the pump door being opened inadvertently. Theperistaltic system is driven by a step motor via a positive-engagement toothed belt,with the individual blade movements being controlled by an eccentric camshaft.These blades are fully protected by a rubber cover.All important operating parameters are clearly reproduced on an LED display. Thedesired values are entered via a keypad. The unit incorporates state-of-the-art SMDcircuit technology.

5. Special key inputs for auxiliary displaysDisplay test and recall of the last values:Hold the Start/Stop key (18) while turning on the pump. Check whether all displayslight up in the correct sequence (..6789).In this Display test mode, last ml/h, total ml, ml infused and the pressure limit (optionpressure-transducer) of the last infusion will be recalled and displayed.

Display of the software version number:Hold the „Total 1000ml down“ key while turning on the pump. The software versionnumber (µVP5000, r1.xx) is displayed. After about 10 seconds the pump switches tonormal operation.

Display of the configuration:Hold the „Total 100ml down“ key while turning on the pump. The configuration(µVP5000, c.xxx) is displayed. After about 10 seconds the pump switches to normaloperation.

Display of the pump serial number:Hold the „Total 10ml down“ key while turning on the pump. The pump serial number(P.nr. xx.xx xxxx) is displayed. After about 10 seconds the pump switches to normaloperation.

Display of the hospital inventory number:Hold the „Total 1ml down“ key while turning on the pump. The hospital inventorynumber (no xxxx) is displayed. After about 10 seconds the pump switches to normaloperation.

Micro-pumping-mode:Hold the „Rate1ml down“ key while turning on the pump. The pump switches to themicro pump mode. Rates can be set from 0.1 to 99.9 ml/h and the total volume to beinfused from 0.1 to 999.9 ml. Carefully watch the decimal point in the 3 displays.Otherwise the pump operates exactly the same as the standard version 1 to 999ml/h.Attention: When turned off in the micro pump mode, the µVP5000 automaticallyreverts to its standard version when switched on again, unless permanentlyconfigured through the software code access.

Pressure display mode (option):Press audible alarm 2 min. suppression key (19) once while the pump is running.Line pressure in mbar or mmHg will be displayed for 20 sec in the ml infuseddisplay (14). By pressing the same key twice in quick succession, not only will thepressure in mbar or mmHg be displayed in the ml infused display (14), but thepressure level will also be displayed in the total ml display (12). During this 20 sectime period, the pressure level can be adjusted below or above the preset 800 mbaror mmHg to a maximum of 999 or a minimum to suit the displayed in line pressure.Remember the lower the pressure level, the lower the bolus occlusion on releaseand the quicker the time to alarm. As soon as the line pressure exceeds theprescribed pressure level, the pump will go into occlusion alarm in the alarmwindow (16). An audible alarm will also be triggered. Once the occlusion has beenreleased, the visual occlusion symbol will flash, and both the general alarm !and audible alarm will continue until the START/STOP key (18) has been pressed.

Caution: Do not open the door if the system is under pressure!Page 11

8. Significance of trumpet curves for practical use

Trumpet curves indicate for 5 different observation windows the maximum and minimummean values of the flow rate in ratio to the preset flow rate.Known therefore is the discrepancy per time-window. For optimal use of the infusion pumpVolumed® µVP5000, the trumpet curve is an important factor in deciding whether the pumpcan be used with the prescribed drug.

Volatile drugs with short therapheutic half life demand high accuracy.

For a drug where the plasma-half life is e.g. 1 min. discrepancy of the flow rate of 15% perminute would mean the same discrepancy for the plasma level. Therefore, a predictableconstant impact of the drug would not be guaranteed.

Example:

Intraveinous infused Insulin has a therapheutic half life of 15 minutes. A flow deviation of ±15% within 40 minutes would have the same (and even greater) influence on deviation ofthe plasma level and therefore on its impact.

This is inacceptable to physicians and nursing personel.

It is important to know that the deviation in a short observation window depends strongly onthe preset rate. The Volumed® µVP5000 has at a rate of 5 ml/h a deviation if ±7% in awindow of 2 minutes and ± 3% in a window of 5 min.However, at a rate if 25ml/h, the deviation is smaller than 2% for a observation window of2 minutes (see also following table).

9. Technical description9.1 Introduction

The microprocessor controlled peristaltic pump Volumed® µVP5000 is suppliedwith a step motor drive and comprehensive software monitoring. The operatingrange of the pump allows rates from 0.1-999 ml/h to be selected. An integrated,rechargeable battery permits mains-independent operation for emergencies or forambulatory use.A mechanical stop flow is installed behind the door to prevent the infusion solutionfrom flowing freely in the event of the pump door being opened inadvertently. Theperistaltic system is driven by a step motor via a positive-engagement toothed belt,with the individual blade movements being controlled by an eccentric camshaft.These blades are fully protected by a rubber cover.All important operating parameters are clearly reproduced on an LED display. Thedesired values are entered via a keypad. The unit incorporates state-of-the-art SMDcircuit technology.

9.2 Circuit description

9.2.1 Microcontroller

Microcontroller D1 monitors the following signals :

Drip detectorThe drip chamber is monitored by a light barrier.Each falling drop produces a signal which is amplified in the OP N2, lengthened inmonoflop D7 and processed by the microcontroller.

Motor controllerMotor controller D10 controls the step motor driver D11 which activates the stepmotor in chopper mode. Simultaneously, after eight step motor pulses it supplies anacknowledge signal, the arrival of which in the motor controller is monitored by thesoftware.

Pump camshaft rotation pulsesMounted adjacent to the pump camshaft is a hall sensor N12 which produces apulse for each revolution of the pump camshaft. The chronological frequency of thisis monitored in the microcontroller by the software.

Air detectorIf air is present, the air bubble detector produces a signal which is monitored in themicrocontroller in combination with the delivery rate.The air bubble detector is periodically checked for correct functioning(AirDetectorTest). This high frequency detector is capable of monitoring both clearand opaque fluids.

Pressure transducer (optional)The pressure from the tubing is measured with the temperature compensatedpressure transducer (Whetstone bridge) which transmits an analog signalcorresponding to the pressure in the line. The signal is converted with an A/Dconverter in the microprocessor conditioned and monitored in the microcontroller.The pressure can be displayed and the pressure limit can be set by the user. If thepressure exceeds the set pressure limit, an occlusion alarm stops the pump. Alsoopening the door is detected and the pump can not be restarted until the door isclosed.

Page 17

WatchdogThe watchdog circuit D6 monitors the program run time. If the time limits areexceeded or fall, semiconductor relay V1 interrupts the supply to the step motor. Afault is signaled to the microcontroller via inverter D5. The relay V1 is periodicallytested via the SM-Test connection. A second watchdog is located in themicrocontroller which also monitors the program run time.

Operating voltagesThe supply voltage, the 5V - and reference voltage are measured and monitored viadisc resistors by the analog/digital converter in the microcontroller.

Mains/battery operationThe level of the operating voltage determines whether operation is from mains orbattery.

Battery voltageWith battery operation the battery alarm is activated if the minimum operatingvoltage falls below limits and in the case of exhaustive discharge voltage, the unit isswitched off.

Microcontroller D1 activates the following signals :

Step motor pulsesThe step motor pulses are delivered by the microcontroller from the quartzfrequency corresponding to the desired delivery rate.

Step motor Start/StopThe microcontroller produces the Start/Stop signal for the step motor on the basis ofthe operating status. This is supplied to the motor controller D10 via the inverter D4.

WatchdogWatchdog D6 is periodically triggered after each program run.

Buzzer (audible alarm)Dependent on the operating status the microcontroller activates the audible alarmtransmitter H1 via driver V8.

Alarm relayDepending on the operating status the microcontroller activates the alarm relay K1(nurse call) via inverter D5 and driver V9.

On/Off functionAfter switching on, the microcontroller activates the holding of semiconductor relayV18. This maintains the supply voltage on. On actuating the key "I/0" or in the caseof a discharged battery, the microprocessor cuts off the supply via semiconductorrelay V18.

A/D converterThe microcontroller controls the internal A/D converter and evaluates the results.

EEPROM memoryImportant data and preset values are stored in the non-volatile memory D4. Also incase of a completely discharged battery the data will be maintained and read backafter the next power on.

9.2.2 Display

The status and the important data are displayed by pictograms and 7 segment LEDdisplays. The display drivers M2, M3 and M4 are controlled by the circuits D3 andM1 and multiplexed by the microcontroller.

The green mains-LED is supplied directly from the transformer.

9.2.3 Setting of the desired data

All the inputs are actioned by the keys on the front panel and are periodicallychecked by the microcontroller. Only the „ON/OFF“-key is separately connected andcontrols the power on circuit. Power off is however controlled via the microcontroller.The keys have the following meaning:

Start/Stop of the pump Start/Stop (21)Alarm tone-mute (for 2 minutes) Alarm tone mute (22)

9.2.4 Power supply

The power supply from the mains is effected via the mains transformer and rectifierV14. In the case of a power supply failure, power is supplied without interruptionfrom the integrated battery unit. Charging circuit V16 provides for constant batterycharging while the unit is connected to the mains (also when switched off).

The electronic relay V18 switches the supply on or off. This function is activatedfirstly by the ON/OFF key and secondly by a hold command from the microprocessorvia inverter D5.Additionally the microprocessor can disconnect the supply in the same manner.Switching controller N3 produces the +5V logic voltage.

11.1 Inspection and maintenance intervals

Cleaning / Desinfection

CAUTION: The pump must be switched off and disconnected from the mains powersupply before cleaning and disinfecting.

The pump must be kept clean and dry. Remove any spillage immediately. Thepump must not be placed in an autoclave.The unit is disinfected by wiping over with a cloth which has been damped slightlywith an alcohol-based disinfectant. Take care when cleaning that no liquid entersthe inside of the pump case. Wait at least 30 seconds after disinfecting beforeswitching the pump on.

Maintenance intervals with safety testing

With the exception of the nickel-cadmium (or ‘green‘ nickel hydrid) battery, the unithas no wearing parts which are subject to regular replacement. As a consequence,the condition of the battery and a visual inspection of the inside of the unit forcontamination or loose or damaged parts is to be performed. If necessary, theinterior of the unit is to be cleaned.The battery is checked by switching off the unit and leaving it connected to themains for 15 hours so that the battery can be fully charged. This is followed byswitching the unit on and allowing it to run from the battery, with the time beingmeasured until the battery alarm is triggered. It should amount to a minimum of 3hours (1.2Ah battery). A battery can be regenerated in some cases by repeatedcharging and discharging (memory effect).

The safety testing can only be done by qualified personnel and has to be inaccordance with the safety requirements.

The inspection and safety testing of the unit is to comprise cleaning as well asperforming visual checks for damage, checking alarm operation and verification ofthe accuracy of delivery. No intervention inside the unit is necessary.The alarm functions are checked as follows :

- Install a water filled tubing, but remove the drip chamber from the emptycontainer detector.

- The display test is actuated by pressing the "START/STOP" key while the unit isswitched on. Check that all indicator lamps and the audible alarm functionproperly.

- Set rate 20 ml/h and start. The bottle/container empty alarm must be activatedafter 60 sec.

- Set rate 500 ml/h and start. The drop alarm must be activated after approx. 2 sec.- Simulate drops by placing a finger through the drip detector light barrier. After 22

drops the alarm must be activated.- Remove the tubing from the air detector, the air alarm will be activated.- Optional pressure transducer: Test of the response to a complete occlusion.

Tubing must be filled completely with water. Rate 100 ml/h. Pressure limit set to500 mbar (360 mmHg) above actual pressure reading. Response time approx.15 sec. (± 10 sec). Long term test: Let the pump run for 24h at different rates (e.g.

Page 23

25 ml/h, 100 ml/h, 999 ml/h). No unexpected alarms.- Switch off the unit.

The delivery accuracy is checked for instance by entering a "TOTAL" of 25 ml witha rate of 250 ml/h. Over a period of six minutes, 25 cm3 or 25 g +/- 5% of watershould be delivered into a measuring beaker.

Electrical safety testing is to be carried out according to IEC regulations and is tocomprise measuring the protective conductor as well as checking the leakagecurrent.The protective conductor connection in the unit is to be tested according to IEC 601part 1, section 18 and is not to exceed 0.1 ohm.

The leakage current is to be tested according to IEC 601 part 1, section 19. In noevent is it to exceed 0.1 mA.
