1. Description
1.1 Purpose
ACCUVAC Basic is a mobile and portable electrically
powered aspirator (suction pump).
It is used for:
•aspirating accumulations of blood, secretions and
food from the oral cavity, the nose and throat
region and the bronchial system;
• deflating vacuum matresses and inflatable splints.
ACCUVAC Basic:
• can when used by a skilled operator eliminate
obstruction of the respiratory tract and hence the
risk of respiratory failure;
• cuts energy consumption by reducing power
output on reaching the necessary vacuum;
• can optionally be powered by a rechargeable
internal power pack;
• or by an external DC source supplying 12.0 -
13.8 V;
• is also suitable for use in wards.
ACCUVAC Basic must not be used:
• in medical rooms where potential equalization is
necessary (e.g. heart surgery);
• in explosion-risk areas.

Description 3
1.2 Function
An electrically operated diaphragm pump generates
the vacuum necessary for aspiration.
Use the vacuum control 2to set the desired vacuum,
which is continuously variable between –0.05 bar
and –0.8 bar. You can read off the set value on the
pressure gage 1.
The aspirated material passes via the aspiration tube
19 into the disposable collection canister 7.
Disposable collection canister
The disposable collection canister 7consists of the col-
lection canister 24 itself, the disposable collection bag
21, the aspiration tube with fingertip 19, the interme-
diate tube 20, the T-piece 23 and the vacuum tube 22.
The disposable collection canister 7is inserted in the
holder 25 screwed on the side of the motor unit 8.
The vacuum tube 22 of the disposable canister 24 is
pushed onto the suction port 14 of the motor unit 8.
The aspirated material passes through the aspiration
tube 19 into the disposable collection bag 21. The dis-
posable collection bag is intended for once-only use.
When it is full, you can remove it from the collection
canister 24 and dispose of it complete with contents.
An overflow valve filter is integrated in the disposable
collection bag 21. This prevents secretions and liquid
from finding their way into the motor unit 8and passing
into the environment via the muffler 13.

Power supply
Power for operating the appliance and charging the
power pack can be drawn:
• from the built-in power pack 17.
• from a 12-volt electrical cable system, using the
connecting cable WM 10650 which is available
as an accessory.
• from the mains and charger unit WM 2645
which is available as an accessory.
Important The AC adapter/charger plug 11 supplied with the
appliance is only designed for charging the power
pack with the appliance switched off. It must not be
used to operate the appliance itself, as this will over-
load it and cause it to overheat.
The voltage indicator 3shows the charge status of the
power pack.
Charging of the power pack starts automatically as
soon as the appliance is switched off and connected
to an external power supply (see “10. Technical Data”
on page 37).

2.2 Safety rules
For your own safety and the safety of your patients,
and in accordance with the requirements of the
93/42/EEC, we would draw your attention to the
following points:
•Please read these operating instructions carefully.
They belong to the appliance and must be kept
available at all times.
• Before working with ACCUVAC Basic, you must
understand how to use it.
• Be sure to observe these operating instructions
when working with ACCUVAC Basic.

6Safety
•To avoid infection or contamination with bacteria
please read section “5. Hygienic preparation” on
page 19.
• ACCUVAC Basic may only be used by trained
staff instructed in aspiration techniques. Incorrect
use can cause serious bodily harm.
•ACCUVAC Basic must be used for the designated
purpose only (see “1.1 Purpose” on page 2).
• Maintenance operations such as inspection and
repair work must be performed by expert person-
nel or by the manufacturer Weinmann.
• Malfunctions and a lack of biocompatibility may
result if third-party articles are used. Please bear in
mind that in these cases any warranty entitlement
and liability shall lapse where the accessories rec-
ommended in the instructions for use or original
spare parts are not utilised.
•During the aspiration process, take particular care
not to cause injuries to the patient’s mouth or
throat, e.g. to mucous membrane.
The suction can be interrupted by briefly opening
the fingertip, for example if the nozzle becomes
firmly attached to the skin.
• Ensure sterile conditions during bronchial aspira-
tion, and always use sterile catheters.
Important! • The disposal of liquids such as blood and secre-
tions and any items contaminated with such liquids
should be carried out according to the national
guidelines for hygiene.
• The ACCUVAC Basic should only be operated in
the upright position, in order to prevent liquid from
wetting the overflow valve filter integrated in the
disposable collection bag 21. If this happens, the
overflow valve filter becomes impermeable to air
and the disposable collection bag 21 has to be
changed.

Safety 7
•The AC adapter/charger plug supplied is only for
recharging the power pack when the appliance is
switched off. It must not be used for operating the
appliance itself, as this will overload it and cause
it to overheat.
•To extend its service life, the power pack 17 must
not be allowed to become fully discharged. If the
red charge control LED 3lights up, it is time to re-
charge immediately.
•To eliminate the risk of fully discharging the power
pack, ACCUVAC Basic must never be stored in
an uncharged condition. Always recharge the
power pack first as described in “4.4 Charging
ACCUVAC Basic” on page 16.
•Lead cell power packs discharge even during non-
use. The rate of auto-discharge increases with ris-
ing temperature and amounts to about 20 % after
three months’ non-use at 20 °C. For this reason be
sure to carry out functional checks at the specified
intervals (see “6. Functional check” on page 23).
• Never sterilize the motor unit 8in an autoclave.
•Never dip the motor unit 8in disinfectant solution.
• We recommend keeping alternative means of
aspiration ready in case of appliance failure.
• Do not use mobile telefones right beside
ACCUVAC Basic.
ACCUVAC Basic can however be operated
without any problem in the back of an ambulance
even if a mobile telephone is being used in the
cab.

holder 38. Since the collection canister is directly
connected to the suction port 14 of the motor unit
8, there is no need for an intermediate tube.

Assembly 11
3.3 Fitting an accessory bag
The accessory bag WM 10655 is available as an
optional extra. It is used to hold aspiration catheters
and other small parts. The accessory bag cannot be
fitted at the same time as a rinsing glass (see “3.4 Fit-
ting a rinsing glass” on page 11).
1. Use the velcro-type strips to attach the accessory
bag to the loops on the motor unit.
3.4 Fitting a rinsing glass
On the left side of the appliance it is possible to fit an
additional collection canister in the form of a rinsing
glass for holding a rinsing liquid, e.g. water.
The rinsing glass kit WM 15229 consists of:
• Collection canister 37 WM 10631
• Holder set 38 WM 15271
1. Use a pointed object to pierce the two closed drill
holes on the left of the appliance case.

2. Fix the holder 38 to the left side of the appliance.
3. Push the rinsing glass into the holder.

Operation 13
4. Operation
4.1 Preparing for aspiration
1. Unwind the aspiration tube 19 from the tube hold-
er plate 9.
2. If necessary, adapt an aspiration catheter of
suitable size for tracheal or nasopharyngeal aspi-
ration to fit the nozzle.
3. Press the button marked O/I. The lower green LED
for the power indicator and the green LED for the
O/I button lights up.
Do not switch on ACCUVAC Basic while there is
still a vacuum. This would cause the pump motor
to draw too much current when switching on,
which could actuate fuse F2 16.
4. Set the desired vacuum at the vacuum control 2.
For this purpose, close the fingertip with the stop-
per and the suction opening with your thumb.
Wait until the pressure gage 1shows a constant
vacuum. Now use the vacuum control 2to set the
desired vacuum.
ACCUVAC Basic is now ready for operation, and you
can start aspiration.

14 Operation
4.2 Aspiration
During the aspiration process, take care not to cause
any injury to the patient’s mouth and throat region, and
especially to mucous membrane.
• The fingertip can be opened to interrupt suction
briefly, e.g. if the nozzle is clinging to the skin.
You can leave the fingertip open all the time and
keep your thumb over it. To release the suction all
you have to do is lift your thumb.
Important Make sure that ACCUVAC Basic is always upright
during operation so that the overflow valve filter inte-
grated in the disposable collection bag 21 is not wet-
ted by secretion. If the overflow valve filter is wetted
with secretion, it becomes impermeable and the dis-
posable collection bag 21 has to be replaced.
During aspiration, keep an eye on the fluid level in the
disposable collection bag 21 and replace it with a
new one in good time.
Important Be sure to check the power pack charge level at regu-
lar intervals during aspiration. If the red LED on the
voltage indicator 3lights up, aspiration should be con-
tinued with a second appliance. Using the appliance
beyond this point can damage the power pack by
discharging it completely, with the result that its full
capacity will no longer be available.

Operation 15
Disposal of disposable collection bag
1. Pull the end of the aspiration tube with fingertip 19
off the port.
2. Detach the intermediate tube 20 from the T-piece
23 of the collection canister 24.
3. Push the free end of the intermediate tube 20 onto
the connection for the aspiration tube. This closes
the disposable collection bag 21 and reduces the
risk of fluid escaping.
4. Remove the disposable collection bag 21 and dis-
pose of it together with the aspiration tube 19.
Important Be sure to observe the relevant rules for disposal
(see “2. Safety” on page 5).

16 Operation
4.3 After aspiration
After aspiration:
1. Switch off ACCUVAC Basic by pressing the
button marked O/I.
2. Fit a new disposable collection bag 21
(see “ Disposal of disposable collection bag” on
page 15).
3. Clean ACCUVAC Basic (see “5. Hygienic prepa-
ration” on page 19).
4.4 Charging ACCUVAC Basic
We recommend you to charge ACCUVAC Basic as
soon as the yellow voltage indicator LED lights up. By
doing so you will ensure that it operates for an
adequate period next time it is used.
The power supply for charging must deliver 12.0 V –
13.8 V DC and at least 0.3 ampere. A full charge
takes a maximum of 14 hours.
The following sources can be used for charging:
• The AC adapter/charger plug 11 supplied.
•The 12-volt vehicle electrical system with the aid of
the accessory connecting cable WM 10650.
•The mains/charger unit WM 2645 available as
an accessory.
