2. Safety instructions
2.1 Special symbols on the appliance
The symbol on the filter cover 19 draws attention to
the built-in bacteria filter 20. This must be changed
or sterilized after use to prevent the risk of infection
(see “5. Cleaning and disinfecting” in the operation manual).
The warning symbol in the capacity indicator 3
draws attention to the risk of complete discharging,
which could damage the power pack 16. If the
10% LED lights up, it is time to recharge the
ACCUVAC Rescue immediately (see “4.4 Charging the ACCUVAC Rescue” in the operation
manual).
Safety instructions 5
3. Description
3.1 Purpose
ACCUVAC Rescue 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 mattresses and inflatable
splints.
ACCUVAC Rescue:
• 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;
3.2 Function
An electrically powered diaphragm pump generates the vacuum necessary for aspiration.
Use the vacuum control 2 to preselect the desired
vacuum between –0.05 bar and –0.8 bar. The
membrane keyboard 4 is illuminated so that you
can see the operating status even after dark.
• 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.
The ACCUVAC Rescue must not be used:
• in medical rooms where potential
equalization is necessary
(e.g. heart surgery);
• in explosion-risk areas.
Note
Once the preselected vacuum is reached, the pump
switches to standby. If the vacuum changes, the pump
starts up again to restore the vacuum to the preselected level.
The aspirated material passes through the aspiration tube 27 into the collection canister.
Re-usable collection canister
The re-usable collection canister 6 is fixed to the
side of the motor unit and directly connected to the
suction port 13 of the motor unit 7. There is thus no
need for an intermediate tube.
A replaceable hydrophobic bacteria filter 20 in the
secretion cover 23 prevents bacteria and droplets
of moisture from finding their way into the motor
unit 7 and passing into the environment via the
muffler 12.
The bacteria filter is designed for multiple re-use
and sterilisation.
6 Description
Important: Do not immerse the bacteria filter in dis-
infectant liquid, as this adversely affects its hydrophobic properties.
An overfill system prevents secretions from entering
the motor unit. The ball 24 floats on the surface of
the secretion until it blocks the exit.
Power supply
Power can be drawn from:
• the built-in power pack 16.
• a 12-volt vehicle electrical system, using the
connecting cable.
• the mains and charger unit available as an
accessory.
The capacity indicator 3 shows the charge status
of the power pack in percent.
Charging of the power pack starts automatically
as soon as the appliance is switched off and connected to an external power supply (see ”13.
Technical Data“ on page 30).
4. Operation
ACCUVAC Rescue may only be used by trained staff
instructed in aspiration techniques. Incorrect use can
cause serious bodily harm.
Operation is described in the operating
instructions.

6. Maintenance
The ACCUVAC Rescue needs no maintenance,
but please be sure to observe the intervals specified for regular final checks (see ”7.1 Intervals“ on
page 9).
To maintain battery operation and service life we
recommend performing calibration every 8 weeks
according to item 7.1.2 of the description and
6.1 Disposal
Do not dispose of the unit with domestic waste. For proper waste disposal of the equipment, please
contact an approved and certified waste disposal site for electronic goods. Ask your Environmental
Officer or town council for the address.
7. Function checks
operating instructions. This process involves the
necessary specific battery discharging and
recharging.
We recommend that you have any servicing, such
as inspections and repair work, carried out by the
manufacturer – Weinmann – or by expert
personnel.
If the final check reveals defects or deviations from
the specified values, the ACCUVAC Rescue must
not be used again until the faults have been rectified.
7.1 Intervals
To ensure that a properly functioning
ACCUVAC Rescue is always available, it is essential to observe the following intervals.
Before every use
• Perform a function check (see ”7.2 Performing
the function check“ on page 10).
After every use
• Clean, disinfect and/or sterilize the unit and
its parts (see operating instructions “5.
Cleaning and disinfecting”);
• Perform a function check (see ”7.2 Performing
the function check“ on page 10).
Every 6 weeks
• Check the power pack charge level by switching on the ACCUVAC Rescue and reading the
We recommend that you always keep a stock of
the following:
• Aspiration tube 27, WM 10662
• Nozzle with fingertip 26, WM 10666
• Filter 20, WM 10675
capacity indicator. If the capacity is 50% or
less, you should recharge the power pack (see
operating instructions “4.4 Charging the
ACCUVAC Rescue”).
At least every 6 months
• Perform a function check (see ”7.2 Performing
the function check“ on page 10).
• Make a visual inspection of the muffler for
clogging. If it is clogged, fit a new muffler (see
”9.13 Changing the muffler“ on page 25).
After all repairs
• Clean, disinfect and/or sterilize the unit and
its parts (see operating instructions “5. Cleaning and disinfecting”);
• Perform a function check (see ”7.2 Performing
the function check“ on page 10).
Maintenance 9
7.2 Performing the function check
1. Assemble ACCUVAC Rescue ready for use.
2. Check that all tubes, the collection canister 28,
secretion cover 23 and filter cover 19 are in
perfect condition. Any damaged and/or worn
parts must be replaced.
4. Switch on the ACCUVAC Rescue.
All LEDs light up for one second after switching
on. After that, only those LEDs that indicate the
operating status stay on. Check the charge
level of the power pack by reading the
capacity indicator 3. If necessary, recharge
the power pack (see operating instructions
“4.4 Charging the ACCUVAC Rescue”).
5. Battery test
A battery test should always be performed
when there are doubts about the performance
of the rechargeable battery, however at the
latest two years after the battery was last
changed.
Procedure:
Charge the ACCUVAC Rescue for 8 hours using the WM 2645 mains charger or for 14
hours using the WM 10750 plug-in power
supply unit. Set a short interval timer to 20 minutes and start the ACCUVAC. After an operating time of 20 minutes the red LED should not
be lit up and the ACCUVAC should be in operation.
If the red LED lights up after 20 minutes, or the
ACCUVAC is no longer working, the battery
is spent and must be replaced. In this case
please replace the battery as described in
section 9.6.
6. Insert the stopper in the fingertip.
3. Check that all tubes are securely connected
and that the secretion cover 23 is firmly in
place.
stopper
7. Use your thumb to hold the nozzle
8. Switch on the aspirator and preselect the maximum vacuum of –0.8 bar. The
ACCUVAC Rescue must reach this vacuum in
not more than 20 seconds. You can tell that
this is the case because the pump stops.
If it takes more than 20 seconds before the
pump stops, the suction capacity is reduced.
Check for possible faults (see ”8. Troubleshooting“ on page 12).
10 Function checks
26 closed.
9. Open the suction opening of the nozzle 26.
The aspirator must start running again.
10. Preselect a vacuum of –0.3 bar.
11. Close the end of the nozzle 26 again.
12. As soon as the pump stops, select a vacuum of
–0.2 bar without opening the fingertip.
The vacuum must not fall to –0.2 bar within 10
seconds.
You can tell that the vacuum is falling off by the
fact that the LED above the –0.2 bar button
starts flashing and the pump starts up. This
means there is a leak. In this case check all
tube connections and the re-usable collection
canister 6.
13. Connect the test pressure gage 0 to –1 bar to
the fingertip.
14. Check the accuracy of all suction levels with
the test pressure gage. Start at –0.05 bar. The
tolerance of the individual suction levels must
not exceed +/– 0.04 bar (5% of end value on
scale).
15. Remove the test pressure gage from the fingertip.
