USAGE APPLICATIONS - DEEP DRAINAGE/GASTRO-INTESTINAL SUCTION
IMPACT MODELS 306/306M AND 326/326M PORTABLE ASPIRATORS
Deep drainage/gastro-intestinal suction, frequently referred to as Wangensteen suction (after Dr. Owen H.
Wangensteen*), requires a thorough understanding of "mild suction" procedures including collection bottle
placement and tubing lengths. The following data is for reference only and specific applications may warrant
deviations and/or additional considerations.
The Impact Models 306/306M and 326/326M are capable of maintaining precise vacuum and airflow levels.
ON/OFF cycling times may be varied from patient to patient effectively optimizing drainage intervals. Cycling
oe are ea arbitrary. It is recommended that the user select intervals consistent with past practices
and protocols.
The gastro-intestinal tract represents a pliable area which when subjected to continuous negative pressure will
collapse around an implanted drainage tube. Such a collapse can cause continuous suction in a specific tissue
area, thus preventing additional drainage while fluids accumulate and potential ulcerations can lead to perfora-
tions and hemorrhage at the collapsed site.
The intended action of intermitte at suction is to provide a hydraulic effect whereby drainage fluids are pulled
and pushed during ON and OFF cycles. The "pull" effect occurs as suction is applied to the gastro-intestinal
tract, thus removing accumulated fluids. The "push" effect occurs when fluid in the elevated connecting tubing
(18" maximum height) flows back into the drainage site, washing" the implanted catheter away from the intes-
tinal wall, thus relocating it in time for the next ON cycle.
It is important to note that the height of the collection canister and placement "dressing” of the connecting
tubing each has a critical effect on overall performance. Under normal conditions, vacuum levels of 90 mmHg
and 120 mmHg would raise a column of water approximately 4’ and 5’ respectively. It is possible that mild suc-
tion, involving particulate matter (solids), blood clots, and viscous secretions could present a situation whereby
the delivered suction strength can only raise the drained contents to a height of roughly 3’ to 4’. To compensate
for this effect, the user is cautioned not to exceed an 18" height between collection bottle entry point and the dis-
tal end of the implanted suction catheter. The user should also be discouraged from using excessive lengths of
connecting tubing. Since mild suction consists of minimal airflow, excessive tubing lengths could prevent fluid
from actually entering the collection canister prior to the beginning of the next OFF cycle. The actual length of
the ON cycle can be extended to compensate for this, however, the clinician must always recognize that an in-
creased possibility of tissue occlusion exists.
The hydraulic action previously discussed is only possible when the collection canister is at a height greater
than the distal end of the implanted catheter. During OFF cycles, the Models 306/306M and 326/326M vent to
atmospheric pressure, enabling a gravitational backflow to occur. If the collecting jar is positioned below the
height of the distal end of the implanted catheter, a siphoning effect can occur. Siphoning will act as a con-
tinuous suction presence between patient and collection canister which is undesireable. Cycling between the
Models 306/306M and 326/326M and collection canister will continue despite siphoning. Clinicians may have
visual objections to the appearance of drained fluids and seek options regarding collection canister placement.
The factors involving the time cycles (ON and OFF), collection canister height and connecting tubing must be
considered in order to have safe, effective intermittent suction.

5. A disposable hydrophobic/bacterial/overflow filter is provided for use with Impact’s standard autoclavable collec-
tion canisters. This filter connects between the Vacuum Inlet Fitting (2) and collection canister (Figure 2). This filter
should be replaced when discoloration of its membrane occurs, the membrane contacts aspirate, or following 150
cumulative hours of use. This filter is designed to retain bacteria which would otherwise be exhausted into the im-
mediate vicinity. The filter’s retention of aerosolized aspirate and will create more resistance to airflow resistance. It is
important that the operator be aware of this and replace the filter accordingly.
6. Disposable collection canisters, traditionally include a built-in filter and may be used with your Model 326/326M. It
is not necessary to use the disposable filter in conjunction with disposable canisters.
7. Reusable canisters should be used with the disposable filter to prevent inadvertent overflow, damage or contamina-
tion of the pump mechanism.
VACUUM REGULATOR (LIMITER)
The Vacuum Regulator (Limiter) (10) works in conjunction with the Vacuum Gauge (4). Vacuum levels may be
selected by rotating the Vacuum Regulator (Limiter) (10): clockwise to increase vacuum; counterclockwise to decrease
vacuum. Vacuum regulator adjustments should be made to the maximum desired vacuum level by "pinching" and hold-
ing the vacuum tubing going to the patient. Deliverable vacuum levels will not exceed this preset maximum. Adjusted
and delivered vacuum levels will continuously display during operation on the dual-scale Vacuum Gauge (4).
COLLECTION CANISTER
Protect the suction mechanism from overflows which may permanently damage the vacuum pump if not properly and
promptly cleaned. Use the disposable filter in conjunction with reusable collection canisters.
Collection canisters may be repeatedly sterilized via autoclave, ethylene dioxide gas or cold liquid sterilants (diluted in
accordance with their respective instructions). DO NOT use abrasive cleansing agents. To determine compatibility with
commercially available cleanser/disinfectants please note the following material content:
Collection Canister Bottle: Polysulfone/Polycarbonate
Collection Canister Cap: EPDM
Hose Fittings: Stainless Steel

BATTERY CARE
The Model 326/326M utilizes sealed G=L cell batteries which offer excellent charge retention characteristics, par-
ticularly during long periods of storage. This ensures an ample amount of power during emergencies and transitory pro-
cedures. The battery pack in this device is not intended for use as the primary power source, therefore, it should be used
with discretion and its design understood. To provide long life and maximum performance capabilities, the Model
326/326M requires 16-hours to fully recharge its fully discharged batteries. Of course, the batteries are rarely discharged
this much so the subsequent recharge time is usually less. GEL Cell batteries require little user care to provide optimum
performance and life expectancy. Because their self-discharge rate is extremely low (approximately 1 1/2% per month),
lengthy periods of disuse without replenishment charging is possible. If long-term disuse is common, it would be advise-
able to recharge the unit once every two months. This will insure that battery charge is maintained at 80% capacity or
better. Continuous battery recharging from the AC mains is permissible but not required. Recharging from 115 or 230
VAC is accomplished using the AC/DC Power Supply accessory supplied with the Model 326/326M. Batteries can be
recharged from an external 12VDC power source too. For external 12VDC operation or recharge, a connecting cable
with automotive plug is furnished. The External Power Input Jack (3) is located on the connector panel adjacent to the
Vacuum Inlet Fitting (2).
The External Power Input Jack (3) will accept voltages ranging between 11 and 30 VDC for device operation and/or
battery recharging. An appropriate cable, to interface between the External Power Input Jack (3) and the power source
is required.
The life of these batteries depends, to a great extent, upon the care they receive. Following these simple guidelines will
prevent premature charge depletion and reduction of battery life.
1. DO NOT operate this instrument where the temperature range exceeds -60‘C to 60‘C (-76F to 140‘F).
2. DO NOT charge this instrument where the temperature range exceeds -20'C to 50‘C (-4‘F to 122F).
3. DO NOT store this instrument with the batteries discharged. Always store in a charged condition.
4. For long-term storage, the optimum storage temperature range is 10°C to 30°C (50'F to 80“F).

ROUTINE CARE AND MAINTENANCE
CLEANING
Note: Routine decontaminations which do not involve the removal of aspirate can be effected using a spray disinfec-
tant. With the device operating, simply spray a small amount of disinfectant directly into the collection canister and
shortly thereafter into the Vacuum Inlet Fitting (2). This should be performed after each use to avoid risk of bacterial
growth. In the event of an aspirate overflow, remove the pump head assembly (SECTION IL. SERVICE, DISASSEMB-
LY/REASSEMBLY). All pump head components may be sterilized using a liquid disinfectant, a mild spray disinfectant
or ethylene oxide gas. DISCONNECT AC/DC POWER SUPPLY OR AUTO POWER CABLE FROM MODEL
326/326M PRIOR TO CLEANING.
© Component Removal
The collection canister(s) and filter should be detached to facilitate cleaning.
e Exterior Case
Periodically or when applicable, clean the exterior case using a mild, non- abrasive cleanser. Disconnect Remove col-
lection canister(s) and filter. DO NOT immerse or allow liquids to enter the case. A damp cloth will suffice in most in-
stances. Disinfectant spraying is recommended at regular intervals. Allow to dry.
e Collection Canister
Impact’s reusable collection canisters may be repeatedly sterilized via autoclave, ethylene oxide gas or cold liquid
sterilants (diluted in accordance with their respective instructions). Do not use abrasive cleansing agents. To determine
compatibility with commercially available cleanser/disinfectants please note the following material content:
Collection Canister Bottle: Polysulfone/Polycarbonate
Collection Canister Cap: EPDM
Hose Fittings: Stainless steel
1. Thoroughly clean collection canister(s), and fittings after each use. Handy hint: Before emptying collection
canister, cap both hose fittings with a short length of tubing. This will prevent accidental spillage of aspirate.
2. Tubing is considered disposable and should be discarded following each use.
3. Insure that all parts are securely fastened and properly connected after cleaning.
4. Orient collection canister and route tubing as shown in Figure 2 following cleaning.
5.
To
prevent
risk
of
cross
contamination
and
the
spread
of

particulate
matter,
the
use
of
bacterial
filters
is
recommended.
If
filters
are not
used,
this
device
should
be
disinfected
and
cleaned,
following
each
use,

ROUTINE CARE AND MAINTENANCE (cont’d)
e Bacterial/Overflow Filter
Do not attempt to clean disposable bacterial/overflow filters. This item is disposable and should be replaced whenever
it becomes discolored or contacts aspirate, airflow is impeded, or following 150 cumulative hours of use, whichever
comes first.
Do not bypass this filter. Its intended use is to retain bacteria which would be expelled through the exhaust port or al-
lowed to accumulate in the pump head _ As filters become occluded with particulate matter during repeated usages, a
reduction in device airflow will become evident. Filter replacement will restore device performance to its normal airflow
levels.
MAINTENANCE
Routine maintenance should be performed on this apparatus at regular intervals and prior to its being placed into ser-
vice. Routine maintenance should consist of the following:
1. Cleaning checks - as described above.
2. Filter checks - replace when discolored, contact with aspirate occurs, airflow performance diminishes considerably
or following 150 hours of cumulative nse.
3. Operational checks - as described in OPERATOR PERFORMANCE CHECKS.
4. Tubing checks - replace crimped, cracked or worn tubing as required.

OPERATOR CORRECTIBLE PROBLEMS
Common problems may be quickly rectified by users. Should the Model 326/326M fail to operate properly, verify the
integrity of all tube connections, tubing, fittings, and control settings. One can quickly isolate problems to an accessory
item or the suction apparatus by testing for vacuum at various locations.
To isolate a problem, check for vacuum at the inlet of each item, tracing backwards through the system, i.e.: vacuum
from the collection canister to the to the Vacuum Inlet Fitting; or if a filter is used: vacuum from the collection canister
to the filter, then vacuum from the filter to the Vacuum Inlet Fitting.
OPERATOR PROBLEMS REQUIRING SERVICE
If the tests described above do not resolve an operating problem, service is required. Should servicing be necessary,
contact your nearest Impact representative or the Impact Customer Service Department [phone].
Please have the Model and Serial Numbers ready and any other pertinent data you wish to include in your service re-
quest. The Model 326/326M Serial Number is located on the outer case identification label.
