1. Introduction
1.0 Introduction
The Volumed® µVP7000 Volumetric Infusion Pump has been developed using
the latest state-of-the-art technology. This microprocessor-controlled volumetric
pump operates by pumping the infusate using a peristaltic system. The sterility of
the infusate is not affected. The pump is designed to infuse drugs or other
infusates into the patient by controlled means under pressure.
The Volumed µVP7000 meets the performance requirements of the MDA (UK) for
neonatal and high risk infusions. It can be used in both stationary and
transportable applications as it has a battery life up to 6 hours duration.
Applications include neonatology, intensive and cardiac care, paediatrics,
gynaecology and osbstetrics, surgery and general medicine. It can also be used
in ambulances or for laboratory use. For infusions with very small rates and small
volumes it is recommended to use a syringe pump such as the Syramed®
µSP6000 as the the remaining volume in the administration set can become
significant compared to the infused volume.
The Volumed µVP7000 meets the Medical Device Directive (MDD) requirements
of the EC Guideline 93/42 EEC and is marked CE.
Classification: Class IIb
The manufacturer according to MDD is Arcomed AG, Althardstrasse 146, CH
8105 Regensdorf, Zurich, Switzerland. Responsible for the EC is Arcomedical
Infusion Ltd., West Horndon, EssexCM133XS,UK.
The Volumed µVP7000 may be operated only on mains power installed to DIN
57107 VDE 0107 or the appropriate national standards. If the integrity of the
mains power supply protective earth system is in doubt, the pump should be
operated on battery power. Mobile telephones should not be used anywhere
near this equipment.
1.1 Mounting the pump
Check the pump and accompanying accessories for damage when unpacking.
The pump must not be operated if damaged. Should the pump be damaged
contact our Service Department.
Permitted mounting: positioned on a flat horizontal surface or pole mounted on
an infusion stand or rail mounted.
The pump should normally be operated from a mains power supply. The internal
batteries will automatically operate the pump in the event of a power failure.
CAUTION: This pump is not designed for use in areas where there is an
explosion hazard. Environmental requirements as per IEC601-1-2 must be
observed. Do not operate this pump in an environment with high levels of

1.2.1 Cleaning and disinfection
CAUTION: The pump must be switched off and disconnected from the mains
power supply before cleaning and disinfecting.
The pump must be kept clean and dry. Remove any spillage immediately. The
pump must not be placed in an autoclave.
The unit is disinfected by wiping over with a cloth which has been damped
slightly with an alcohol-based disinfectant. Take care when cleaning that no
liquid enters the inside of the pump case. Wait at least 30 seconds after
disinfecting before switching the pump on. Use only disinfectant that are
compliant with:
- ABS, POM, stainless steel, PVC, aluminum, silicone
Please check with your supplier of disinfectant.
1.2.2 Annual safety check
Battery power is provided by a nickel metal hydride (NiMH) battery which must be
checked annually. Battery condition is checked by connecting the pump to the
mains power supply for 15 hours in a switched off condition so that the battery
may be fully charged. Disconnect the mains power supply and switch the pump
on using battery power. Determine the operating time when the low battery alarm
activates. This should be at least 3 hours - if not the battery must be replaced.
Repeated charging and discharging may in certain circumstances cause
degeneration of the battery (memory effect).
Used batteries must be disposed of in an environmentally friendly manner or
returned to the manufacturer.
Safety checks (see chapter 6) may be performed only by qualified staff.

3. Operation
The figures in brackets refer to the illustrations of front and rear views shown in
the appendices.
CAUTION: Use only approved disposable adiministration sets!
(cf. leaflet "Accessories and Consumables")
The performance of the pump depends on both pump and administration set. The
volumed must only be used with the sets the pump has been calibrated to. The
functional safety of the pump cannot be guaranteed if non-approved IV sets are
used. The safety of the patient may be compromised as a result.
Disposable IV sets are for single-use only. Single-use needles carry an infection
hazard and must be disposed of in accordance with local guidelines. The IV-set
should be replaced every 24 hours.
3.1. Preparation and loading of the administration set
a) If the pump is to be operated on an infusion stand, care must be taken that the
pump is not positioned more than 1.4m above the ground to ensure stability.
Ideally use an "Arco Luxe" or "Arco Standard" infusion stand. If several pumps
are mounted one above the other the maximum permitted height from the floor
must be observed and measures taken to prevent instability. The pump
may be fixed to the infusion stand by means of the pole clamp (29) on the rear
of the unit.
b) Slot the drip chamber (2) into the empty container detector (4). Make sure
that there are no large ribs or joints in the passage of the empty container
detector and that fallen drops are detected by the drop-detector‘s light-barrier.
c) Carefully purge the infusion set (1), without allowing any air bubbles to
enter, until the drip chamber (2) is 1/4 to 1/3 full. If air has entered, repeat
purge-procedure.
d) Close the tubing roller clamp.
e) Open the pump door (5) by pulling the latch (6).
f) Pump with Robson Clamp:
Position the Robson clamp (3) on the tubing. In case of a silicon insert
tubing, position the Robson clamp just left of the silicone segment. Close the
Robson clamp. Hold the tubing with your right hand with your thumb
positioned on the Robson clamp. Starting with the left side, insert the IV set
into the left tube guide (11). Ensure that the flow direction of the pump from
the left to the right is respected and the tubing is in a straight line. Put the
Robson clamp with your thumb into the Stop Flow device (14) and insert
the remaining tubing onto the right tube guide (11).
Pump with internal clamp:
Starting with the left side, insert the IV set into the left and right tube guides
(11). Ensure that the flow direction of the pump from the left to the right is
respected and the tubing is in a straight line. In case of a silicon insert tubing
verify the correct position of the silicon insert as shown in the front view of this
manual.
g) Close the door (5) and push the latch (6) firmly against the pump. Open the
tubing roller clamp.Page 5

h) Switch the pump on: Press ON/OFF key ( ) (10). The audible alarm
beeps once together with the indication < ! > in the alarm window (21). The
software version number (µVP7000, rx.xx) and the configuration of the pump
(µVP7000, c.xxx) light up briefly.
Wait until the automatic Stop Flow test is terminated.
i) Check if there is no free flow. Where possible mains power should be used.
Plug the mains power cable into the connector socket (18) at the rear of the
pump. The mains pictogram illuminates as soon as the mains supply is
connected. The battery is charged automatically.
j) The Volumed µVP7000 has the possibility to prime the line with the pump.
Make sure the patient is always disconnected when priming:
Press the bolus key (19) until the LCD display (20) shows: priming? Press and
hold the bolus key until the priming is finished. To terminate the piming mode
press the Start/Stop key (10). Important: during priming both air alarm and
empty bag alarm are ignored. The prime rate is displayed in the rate window
(8).
k) Connect set to the patient.
Important: Before the door is opened, close the roller clamp!
3.2. Setting rate (ml/h) and volume (ml)
Use the UP/DOWN keys (16) to select the required rate in ml/h indicated in the
RATE display (8). Arrow up keys provide rate increase, arrow down keys provide
rate decrease. Check that each key stroke changes one digit. The least
significant digit (small size) indicates 0.1 (units).
If a specific volume (VTBI) is to be infused, the required volume in mls may be
selected in the VOLUME window (10) using the UP/DOWN keys (13) before
starting the pump (optional). Once the VTBI is reached, the pump gives and
audible alarm and displays <INF COMPL> (infusion complete) in the Alarm
window (21). The pump switches to the KVO rate.
Remark: With the empty bag detector (4) the pump stops automatically after the
last drop in the bag. If no empty bag detector is used, the volume (VTBI) has to be
set to stop before the bag is completely emptied. Otherwise the pump the pump
continues infusing until air is detected in the air detector (18). Hence, it is strongly
recommended to use the empty bag detector.
3.3. Pump running
When the pump is running, the green drop symbol flashes (22). The VOLUME
display now indicates the volume infused in mls. In order to display various data,
such as pump condition, volume to be infused, infusion time, time to end of
infusion, battery condition, pressure and pressure limit, press the OPTION key
(18) sequentially and observe the LCD window (20) until the required data is
displayed.
If a specific volume to be infused was selected the pump automatically switches
to KVO operation when this volume has been infused and an audible and visual
alarm (21) activates.
Press the ALARM SILENCE key (5) to silence the audible alarm for 2 minutes.
Page 6

3.4. Resetting the volume infused
In order to reset the volume infused, stop the pump by pressing the STOP key
(10). Press the OPTION key (18) for 2 seconds until the VOLUME display (9)
flashes. When the LCD window (20) displays "000", confirm this by pressing the
START/STOP key (10) to reset the volume infused to zero. If it is not desired to
reset the volume infused, press the OPTION key (18) until the normal display
appears.
3.5. Infusing a bolus
When the pump is infusing, a manual or an automatic bolus can be given.
To infuse a manual bolus:
Press the OPTION key (18) and the BOLUS key (19) together.
The bolus rate is displayed in the RATE window (8) and the bolus volume infused
is displayed in the VOLUME window (9). The LCD window (20) indicates "Bolus
manual". Keep the keys depressed until the required bolus volume has been
infused. As soon as the keys are released the pump reverts to the normal
infusion mode.
To infuse an automatic bolus:
Press the Bolus key (19) for 2 seconds until the display in the VOLUME window
(9) flashes. The desired bolus volume in mls can then be preset in the VOLUME
display using the VOLUME keys (13). Press the BOLUS key (19) to deliver the
bolus automatically. If no bolus is required, press the OPTION key (18) to cancel.
During automatic bolus delivery, the RATE display (8) indicates the bolus rate
and the VOLUME display (9) indicates the bolus volume infused. The LCD
window (20) indicates "Bolus automatic".
To stop the pump at any time press the STOP key (10).
After the selected bolus volume has been delivered, the pump switches
automatically to normal delivery mode.
Following bolus infusion, the bolus volume is added to the total ml infused.
3.6. IV container exchange
When changing the plastic container or bottle, infusion can be interrupted at any
time by means of the 'Start/Stop' key (18) without affecting the set or displayed
values. In this state, handling operations such as changing the container or IV set
and rate changes can be implemented without activating the alarm. In the stop
mode, 'KVO' operation is automatically activated.
If the pump remains in the stop mode for more than 4 minutes, the audible
reminder alarm will sound.
3.7. Recall of previous data
If the pump has been accidentally switched off, data such as rate, volume to be
infused and volume infused may be recalled during start up. Press the
START/STOP key (10) and the ON/OFF key (7) together to recall all data.
3.8. Setting volume and time
If a specific volume is to be infused in a given time the RATE display must be left
at zero. After inserting the IV set, closing the door and finishing the automatic test
press and hold the OPTION key (18) until the RATE and VOLUME displays flash.
Page 7

The time in hours and minutes may be selected in the RATE display (9) and the
volume selected in the VOLUME display (9). The pump automatically calculates
the infusion rate. Check this carefully in the LCD window (20) before starting the
infusion.
3.9. Pressure system
The Volumed µVP7000 has automatic pressure monitoring whereby the pressure
in the system is measured via the pressure transducer. The alarm pressure limit
can be set automatically or manually.
Automatic setting:
If the pump is configured for this mode, the alarm pressure limit is automatically
matched to the set rate, the lower the rate, the lower the alarm pressure limit. The
time to alarm can be viewed in the table of section 2.
Manual setting:
Press the OPTION key (18) sequentially to display pressure and alarm pressure
limit in the LCD window (20). Hold down the OPTION key (18) until the VOLUME
display (9) flashes "Lxxx". The pressure limit may be manually set using the
VOLUME keys (17) in the VOLUME display (9) and the data in the LCD window
changes accordingly. This can also be done while the infusion is in progress.
NOTE: Manual setting of pressure deactivates the automatic pressure setting, i.e.
the pressure remains at the current level independent of the rate selected.
If the pressure rises beyond the limit set, the pump stops and the stored bolus is
automatically reduced to virtually zero volume. An audible and visual alarm is
activated. Check the IV carefully for the cause of the alarm. Do not restart the
pump until the occlusion is released.
3.10. Setting time and date
Press the OPTION key (18) sequentially to display date and time in the LCD
window (20). Hold the OPTION key (18) down until the display flashes. The time
may be set using the volume keys (17) in the Volume display (9), e.g. h9.45 =
9:45 am. This can also be done while the infusion is in progress.
The Volumed has the possibility to automatically adjust the daylight save time
(summer time). The adjustments can be done as per EU, US or Australian
regulations. If the text ‘Clock !’ should appear, replace the Lithium backup battery
on the main PCB.
To set the date, first switch the pump off. Press the VOLUME 0.1 ml DOWN and
VOLUME 100 ml DOWN keys (17) together whilst switching the pump on. This
enables the Service Mode. Select the RATE display (8) according to the
following table using the RATE keys (16). Then select the corresponding data in

The Instructions for Use, the mains power supply cable and the empty bag
detector (optional) are included as standard equipment with the Volumed
µVP7000. For accessories see also 3.19.
3.13. START/STOP key (10)
The START/STOP key (10) is used to start the pump after the rate has been
selected. The pump may be stopped at any time using this key. An additional
function of this key is to confirm various parameters.
3.14. Prime / Bolus key (19)
The PRIME/BOLUS key (19) key is used to prime the extension set. It is also
used to initiate a manual or automatic bolus (3.5).
3.15. AUDIBLE ALARM SILENCE/ OPTION key (18)
The audible alarm may be silenced for 2 minutes using the ALARM
SILENCE/OPTION key (18). The audible alarm is re-activated after this period.
If there is no audible alarm, the key serves as an OPTION key which enables
selection of any option.
3.16. ON/OFF key (7)
The pump may be switched off using the ON/OFF key (7) if the infusion has been
completed. All data displayed (rate and volume) is lost when the pump is
switched off. In order to avoid switching the pump off accidentally, the ON/OFF
key (7) must be pressed for at least one second before the pump switches off.
If the pump is connected to the mains, the STANDBY mode will switch in when
the pump is switched off. This means that the battery will be charged and the
charge condition indicated in the LCD window.
3.17. Keep-Vein-Open (KVO) - Rate
The pump may be configured to infuse at the keep vein open rate when the
volume to be infused has been delivered. The KVO rate is preset at 3.0 ml/h and
may be set (by a technician) to suite individual requirements if necessary. If the
set rate is smaller than than the KVO rate, this rate becomes the KVO rate.
Remark: The latest standard uses the new wording Keep-Open-Rate (KOR). The
meaning is identical to the KVO-rate.
Page 9

3.18. Using the pump in parallel or multiple infusions
If additional infusion systems are connected to the patient's vascular system, this
may lead to complications e.g. infusion of air, reverse-flow, interruptions due to
alarms and inaccurate flow.
To prevent such incidents, please observe the recommendations as stipulated in
DIN VDE 0753, Part 5 or contact your distributor.
3.19. Options for external connection to the pump
External equipment may only be connected to the Nurse call connector (25),
empty bag detector (26) and external supply (27) if the system which results from
this meets the requirements of standard EN60601-1-1 and if their safety has
been certified by an approved international body.
- Use cable number 94070 to connect the Nurse call system. Important: The
alarms on the pump have to be observed also when the nurse call is connected.
- If an external 12 VDC power supply is used and is linked to other equipment,
ensure that the safety of the system complies with IEC60601-1. Use cable
number 71630.
- Use only the external empty conntainer detector Nr. 98502 (4)

4. Alarm system
4.1. Alarm causes
The electronic self-monitoring system continuously monitors the correct
functioning of the pump and its displays whilst in operation. If a fault should
occur, the infusion is stopped
immediately and the alarm activates. The corresponding alarm symbol is
illuminated continuously with a red colour and there is a continuous audible
alarm. The nurse call alarm is activated at the same time.
The pump will not start:
- if no rate has been set (0 ml/h).
- if air is in the line
- if the door is open.
- if the IV set or the Robson clamp is not correctly installed.
During operation an audible alarm activates and the pump switches to the KVO
rate if:
- the START/STOP key is operated.
- the VTBI is reached
- attempts are made to alter the rate during operation.
During operation an audible alarm activates and the pump stops if:
- the roller clamp is not opened.
- the bag is empty.
- battery capacity is low and the charge can no longer ensure controlled infusion.
- the infusion pressure exceeds the limit set.
- the door is opened.
- there is an internal defect.
With empty bag detector:
- if the detected drops do not correspond with the set tolerances.
- if the level in the drip chamber is too high.
4.2. Canceling the alarm condition
After rectifying the cause of the alarm or acknowledging the rate change, the
alarm condition is canceled and infusion resumed by pressing the START/STOP
- key (10).
4.3. Pressure limit/occlusion alarm
If the pressure in the system reaches the set pressure limit due either to a total or
partial occlusion, the alarm activates and the occlusion alarm symbol and rate
display flash. The LCD window displays "occlusion! check line!" The vein site
should be checked to ensure there is no complication.
If the cause of the occlusion is removed, the occlusion symbol flashes and the
pump may be started again.
Page 11

4.3. Battery alarm
The pump may be operated independently of the mains power supply using the
internal battery. If the mains power supply fails, the pump switches automatically
to battery operation to continue the infusion without interruption.
Battery operation is indicated by illumination of the battery symbol (22). Battery
capacity permits from 3 up to 6 hours operation (1.85 Ah battery) depending on
the infusion rate set. After approximately 3 to 6 hours operation the battery
symbol in the alarm display (21) illuminates and an audible alarm activates.

1, 999 ml/h to be made. An internal rechargeable battery allows the unit to
operate independently of the mains in emergencies or when used as a mobile
unit. The mechanism is driven by a step motor via a toothed belt and friction
spindle. All important operating parameters are clearly shown on an LED
indicator. Setting the desired values is done via touch-pad keys. The unit is
manufactured using the latest surface mounted control technology (SMD).

7. Perfomance
7.1 Significance of trumpet curves for practical use
Trumpet curves indicate for 5 different observation windows the maximum and minimum
mean 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
pump Volumed® µVP7000, the trumpet curve is an important factor in deciding whether
the pump can 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%
per minute would mean the same discrepancy for the plasma level. Therefore, a
predictable constant 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 at least the same (rather twice as much) influence
on deviation of the 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
on the preset rate. The Volumed® µVP7000 has at a rate of 25 ml/h a deviation smaller
than ±2% in a observation window of 2 minutes.With 5 ml/h the deviation in the same
observation window is ± 7%, within 5 minutes it is ±3%. Mean deviations are within ±5%
(see also following table).
