Introduction

For decades

WEINMANN has been developing,

manufacturing and marketing appliances for emer

gency medical treatment,

oxygen therapy and

inhalation

therapy.

In 1986

WEINMANN launched the first

ACCUVAC

aspirator on the market.

The improved

ACCUVAC

Basic

aspirator pro

vides users with an appliance that is an indispen

sable aid in many emergency health care situa

tions. The

ACCUVAC

Basic

is primarily intended

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.

The purpose of these Service and Repair Instruc-

tions is to make sure you as an expert specialist are

familiar with the ACCUVAC Basic aspirator: its

functionality and technology and how to repair it.

Combined with training you have already re-

ceived from WEINMANN, this makes you a mem-

ber of the “authorized expert personnel” category,

which means you can give your customers proper

instruction, remedy faults independently, perform

the final checks specified in the Operating Instruc-

tions, and carry out any repairs in accordance with

these Service and Repair Instructions.

In the event of a warranty claim the ACCUVAC Basic

aspirator is to be sent to WEINMANN.

So that we can process warranty claims or re-

quests for generous treatment of complaints,

please send the purchase receipt (invoice) with the

appliance.

Repairs may only be carried out by WEINMANN

or by expert personnel.

You are responsible for any repairs you make and for

the relevant warranty!

Only original WEINMANN spare parts must be used

for repairs.

Please remember:

Your customer trusts you and relies on your quality,

just as you rely on WEINMANN.

2. Description

2.1 Purpose

ACCUVAC Basic is a mobile and portable electri-

cally 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;

• 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.

2.2 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

36 into the disposable collection canister 7.

Disposable collection canister

The disposable collection canister 7consists 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 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.

6Description

The aspirated material passes through the aspira-

tion 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 secre-

tions 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.

• 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 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 con-

nected to an external power supply (see ”12.

Technical Data“ on page 27).

Operation 7

3. Operation

ACCUVAC Basic may only be used by trained staff in-

structed in aspiration techniques. Incorrect use can

cause serious bodily harm.

Operation is described in the operating

instructions.

4. Operating and Display Elements

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 opera-

tion and life, we recommend you to calibrate the

power pack every 8 weeks as described in

Section 8.1.2 of the instructions for use. This in-

cludes 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 per-

sonnel.

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.

8Functional checks

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 fol-

lowing intervals.

Before every use

• Perform a functional check (see ”6.2 Perform-

ing 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 Perform-

ing the functional check“ on page 8).

Every 3 months

•Check the charge level of the power pack 17

by switching on ACCUVAC Basic and read-

ing the voltage indicator 3. If the top LED of the

voltage indicator does not light up, the power

pack should be recharged (see operating in-

structions ”4.4 Charging ACCUVAC Basic“).

At least every 6 months

• Perform a functional check (see ”6.2 Perform-

ing 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 Perform-

ing 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 7are in per-

fect 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.

5. Check the charge level on the voltage indica-

tor 3. Always recharge the power pack with-

out delay if the yellow LED on the voltage

indicator lights up (see operating instructions

”4.4 Charging ACCUVAC Basic“).

Functional checks 9

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 us-

ing the WM 2610 mains / charger unit

FW7405M/14, complete or for 14 hours us-

ing 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 opera-

tion.

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 sec-

tion 8.6.

7. Insert the stopper in the fingertip 19.

8. Use your thumb to hold the suction nozzle

closed.

9. Switch on the aspirator and select the maxi-

mum vacuum of –0.8 bar by turning vacuum

control 2fully 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.
