In 1986
ACCUVAC
The improved
vides users with an appliance that is an indispen
sable aid in many emergency health care situa
tions. The
for oral or transtracheal aspiration of secretion.
Aspiration is indicated in particular for tracheoto
my patients undergoing respiration.
The indications include:
•
Neuromuscular disorders, e.g. paraplegia,
amyotrophic lateral sclerosis (ALS)
•
Late symptoms of polio
• Muscular dystrophies
• Cystic fibrosis
• Kyphoskoliosis and posttubercular syndrome
• Chronic obstructive lung diseases, e.g. severe
chronic bronchitis
• Pulmonary fibrosis, e.g. silicosis
• Other forms of alveolar hypoventilation
Using the ACCUVAC Basic aspirator gives the
user more time to look after the patient and perform
other measures.
WEINMANN has been developing,
oxygen therapy and
therapy.
WEINMANN launched the first
aspirator on the market.

2.1 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 mattresses 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;
2.2 Function
An electrically operated diaphragm pump generates
the vacuum necessary for aspiration.
Use the vacuum control 2 to 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.
• 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.
The aspirated material passes via the aspiration tube
36 into the disposable collection canister 7.
Disposable collection canister
The disposable collection canister 7 consists of the
collection canister 24 itself, the disposable collection
bag 21 with intermediate tube 20, the aspiration tube
with fingertip 19, the T-piece 23 and the vacuum tube
22.
The disposable collection canister 7 is 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.
Description 5
The aspirated material passes through the aspiration tube 19 into the disposable collection bag 21.
The disposable 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 8 and 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.
• a 12-volt electrical cable system, using the
connecting cable WM 10650 which is
available as an accessory.
• 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 overload it and cause it to overheat.
The voltage indicator 3 shows 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 ”12.
Technical Data“ on page 27).

5. Maintenance
The ACCUVAC Basic needs no maintenance, but
please be sure to observe the intervals specified for
regular final checks (see ”6.1 Intervals“ on
page 8).
In the interests of maintaining power pack operation and life, we recommend you to calibrate the
power pack every 8 weeks as described in
5.1 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.
Section 8.1.2 of the instructions for use. This includes the required discharging and recharging of
the power pack.
We recommend that you have any servicing, such
as inspections and repair work, carried out by the
manufacturer – WEINMANN – or by expert personnel.
Operation 7
6. Functional checks
If the final check reveals defects or deviations from
the specified values, ACCUVAC Basic must not be
used again until the faults have been rectified.
We therefore recommend that you always keep a
stock of the following:
• Disposable collection bag 21 WM 10732
• Aspiration tube with
fingertip 19 WM 10733
6.1 Intervals
To ensure that a properly functioning ACCUVAC Basic is always available, it is essential to observe the following intervals.
Before every use
• Perform a functional check (see ”6.2 Performing the functional check“ on page 8).
After every use
• Clean, disinfect and/or sterilize the unit and
its parts (see operating instructions ”5.
Cleaning and disinfecting“);
• Perform a functional check (see ”6.2 Performing the functional check“ on page 8).
Every 3 months
• Check the charge level of the power pack 17
by switching on ACCUVAC Basic and reading the voltage indicator 3. If the top LED of the
voltage indicator does not light up, the power
pack should be recharged (see operating instructions ”4.4 Charging ACCUVAC Basic“).
At least every 6 months
• Perform a functional check (see ”6.2 Performing the functional check“ on page 8).
• Make a visual inspection of the muffler for
clogging. If it is clogged, fit a new muffler (see
”8.14 Changing the muffler“ on page 22).
After all repairs
• Clean, disinfect and/or sterilize the unit and
its parts (see operating instructions ”5.
Cleaning and disinfecting“);
• Perform a functional check (see ”6.2 Performing the functional check“ on page 8).
6.2 Performing the functional check
1. Assemble ACCUVAC Basic ready for use.
2. Check that all tubes and the individual parts of
the disposable collection canister 7 are in perfect condition. Any damaged or worn parts
must be replaced.
3. Check that all tubes are securely connected
and the disposable collection bag 21 is firmly
installed.
4. Switch on ACCUVAC Basic.
8 Functional checks
5. Check the charge level on the voltage indicator 3. Always recharge the power pack without delay if the yellow LED on the voltage
indicator lights up (see operating instructions
”4.4 Charging ACCUVAC Basic“).
6. 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 Basic for 8 hours using the WM 2610 mains / charger unit
FW7405M/14, complete 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 8.6.
7. Insert the stopper in the fingertip 19.
Stopper
8. Use your thumb to hold the suction nozzle
closed.
9. Switch on the aspirator and select the maximum vacuum of –0.8 bar by turning vacuum
control 2 fully to the right. ACCUVAC Basic
must reach this vacuum in not more than
20 seconds.
If the aspirator takes longer than 20 seconds
to reach this vacuum, this means its suction
capacity is reduced. Check for possible faults
(see ”7. Troubleshooting“ on page 10).
10. Attach the test pressure gauge 0 to –1 bar
WM 15294 to the fingertip.
11. Check the maximum vacuum for accuracy with
test pressure gauge 0 to –1 bar. The vacuum
must be –0.8 bar, tolerance +/– 0.04 bar.
12. Remove the test pressure gauge from the
fingertip.
13. Switch ACCUVAC Basic off again.
