3.1 Description
WARNING w Do not use this device in the presence of flammable anesthetics. Static charges
may not dissipate and a possible explosion hazard exists in the presence of
these agents.
The Continuous Vacuum Regulator is a lightweight, compact unit used throughout the hospital primarily for
pharyngeal/tracheal suctioning (airway management). Various models provide regulated or full-line vacuum
for hospital suction procedures.
There are several models of the Continuous Vacuum Regulators. All models contain a vacuum gauge
which indicates suction supplied by the regulator. Each has a positive pressure safety relief valve to
prevent pressurization by either failed injector vacuum (venturi) units or inadvertent cross connection to
pressurized gasses. In addition, the Low Continuous models include a vacuum relief valve to limit maxi-
mum suction.
Some models operate in a regulated or non-regulated (MAX) mode. Others operate only in the regulated
(limited) mode.
In the non-regulated (MAX) mode, the vacuum source is connected directly to the fitting port. The regulator
module is bypassed and full-line vacuum is provided.
In the regulated (limited) mode, the vacuum source is connected through the regulator module which
functions as an automatic valve. Turning the suction control knob adjusts the position of the regulator
module and allows selection of a predetermined level of suction when set according to instructions.
During use, as the flow requirement increases, the valve automatically opens to maintain suction at the
preset level. Conversely, when the flow requirement decreases, the valve automatically closes to maintain
suction at the preset level. The same mechanism compensates for changes in supply vacuum and auto-
matically maintains the pre-set suction level when set according to instructions.
1. Suction Control Knob - Allows easy adjustment of suction to the patient.
2. Mode Selector Switch - Allows quick and easy mode changes.
a. | (On) - Suction can be adjusted with the suction control knob.
b. O (Off) - No suction is supplied to the patient.
c. MAX - Maximum full-line vacuum is supplied to the patient.
3. Vacuum Gauge - The suction level to the patient is displayed during use.

4/Operation
4.1 Equipment Set-up
Insert the probe into the vacuum wall outlet. If the regulator is mounted elsewhere, connect a vacuum supply hose
between the regulator’s probe adapter and the wall outlet.

WARNING w Connect the vacuum regulator to the vacuum source only and check its operation before
attaching the patient connection. Connection to pressure sources, even momentarily, could
injure the patient or operator and damage the equipment.

Note: For proper installation of Adapters/Probes and Fittings see Appendix.

Connect the collection bottle's vacuum port to the regulator's fitting port or Overflow Safety Trap with the appropriate
vacuum tubing.
Use hospital-supplied suction tubing between the end piece and the collection container, and between the patient
port and the patient (minimum inside diameter is 6 mm [0.25 in.]).
ISO 10079-3 (BS 7259: Part 2, section 5.1.2) states that “the usable volume of the collection container shall not be
less than 500 ml.”
An Ohmeda MedicalHigh Flow Suction Filter should be used between the collection container and regulator to
prevent contamination of the regulator.

5/Cleaning and Sterilization

5.1 Cleaning
wWARNING After patient use, regulators may be contaminated. Handle in accordance with
your hospital’s infection control policy.
5.1.1 Routine Exterior Cleaning
Routine cleaning of the regulator is recommended as a standard procedure after each use.
Wipe all exterior surfaces with a solution of water and mild detergent.
5.1.2 Internal Component Cleaning
CAUTION w Cleaning the gauge may result in damage.
The regulator requires cleaning if it becomes flooded with patient fluid as a result of misuse.
1. Refer to the Service - Disassembly and Assembly instructions.
2. All internal components, with the exception of the gauge, may be cleaned with a solution of warm water
and mild detergent, preferably an enzymatic cleaner.
3. Dry all components with a lint free cloth before assembly.

5.2 Sterilization
WARNING w Following sterilization with ethylene oxide, parts should be quarantined in a well
ventilated area to allow dissipation of residual ethylene oxide gas absorbed by the
material. Follow sterilizer manufacturer’s recommendations for specific aeration
periods required.
CAUTION w Do not steam autoclave or liquid sterilize the Continuous Vacuum Regulator. Severe
impairment to the operation of the regulator will result. The only acceptable method of
sterilization is with gas (ethylene oxide).
CAUTION w Sterilization with ethylene oxide mixtures may cause crazing (minute superficial crack-
ing) of some plastic parts. Crazing will be more pronounced when mixtures containing
Freon® are used.
Note: The Vacuum Regulator should only be sterilized if it is contaminated or maintenance is to be per-
formed.
1. The regulator should be sterilized with the mode selector switch in the | (On) position.
2. The only acceptable method of sterilization is with ethylene oxide. Ethylene oxide mixtures can be used
at temperatures of 125 to 135 °F (52 - 57 °C). If this temperature cannot be obtained, room temperature
sterilization with 100% ethylene oxide can also be used. Sterilization is not recommended as a standard
procedure after each use.
3. After each sterilization, check the condition of the internal filter. If the filter appears to have shrunk,
replace it before placing the regulator back in service.
4. Adequately aerate the regulator prior to disassembly, shipment or use. Aerate parts prior to reassembly.

7.3 Suction Level Limit Setting-Low Models ONLY

WARNING w This Low Vacuum Limit Setting Procedure must be followed when repairing Low Vacuum
Regulators. Failure to do this may result in suction exceeding the prescribed level.
The design of the low continuous vacuum regulator has been changed to eliminate the low vacuum limiting
set screws located inside the cover behind the suction control knob. The vacuum relief valve has also been
changed to limit the vacuum to the same level as the set screws did. This new vacuum relief valve has four
vent holes; the old valve had two. If a new cover is used, a new vacuum relief valve must be used.
Versions with limiting screws have two means of limiting the suction level:
1. Low vacuum limiting screws in the cover; these can be set at 140 mmHg ± 10 mmHg (19 kPa ± 1.3 kPa).
2. Vacuum relief valve; this can be set at 165 mmHg ± 15 mmHg (22 kPa ± 2 kPa).
These vacuum limit settings may be reduced to accommodate user requirements. If the vacuum limit
settings are reduced, the vacuum relief valve must be set 25 mmHg ± 15 mmHg (3 kPa ± 2 kPa) higher
than the vacuum limiting screws.
Versions without the limiting screws use only the relief valve to limit the suction level. The relief valve can
be set at 140 mmHg ± 5 mmHg (18.7 kPa ± 0.7 kPa).
7.3.1 Low Vacuum Limiting Screws
CAUTION w When adjusting the vacuum limiting screws,
be sure to adjust them to an equal height.
Cover
CAUTION w Remove the “Increase” label carefully. and Knob
Press firmly in place when replacing. Assembly
1. Remove the “Increase” label and place it aside. Be careful
not to damage the face or glued back of the label.
2. Adjust the two vacuum limiting screws located behind the
suction control knob until they are the same height in
the case. Use a 3/32” hexagonal allen wrench. Allen
3. Connect the vacuum supply to the adapter port Wrench

limiting setscrews and140 mmHg ± 5 mmHg
(18.7 kPa ± 0.7 kPa) for units without limiting Vacuum Relief Valve
setscrews.
6. If adjustment is required, grip the vacuum relief valve firmly with pliers and rotate the screw about 1/8
turn with a screwdriver. Repeat the previous step and check the suction level at which the valve opens.
Note: Clockwise rotation will increase the suction level at which the relief valve opens. Counterclockwise
rotation will decrease it.
WARNING w Excess Loctite® may seal the steel ball to the seat. This will disable the vacuum
relief valve and may allow suction to exceed the preset limit.
CAUTION w When Loctite is used on the vacuum relief safety valve, ensure that it only contacts the
metal parts. Loctite causes many plastic parts to deteriorate.
7. Lock the adjusting screw with a drop of removable thread locker such as Loctite 242. Repeat step 5 to
verify the vacuum relief valve setting.

Appendix
Installation procedure for Adapters/Probes and Fittings.
All adapters/probes and fittings should be sealed and installed properly to prevent leaks and to support the
equipment when mounted. Both vacuum regulator ports are 1/8-27 NPTF tapered pipe threads. It is
important to note that adapters/probes and fittings seal on the thread and may have threads exposed after
they have been tightened properly.
Prior to installing the adapter/probe or fitting, seal the thread with Teflon® (PTFE) tape or one of the follow-
ing lubricants:
Dow® 111 (Ohmeda P/N 6700-0074-200)
Ball Vac Kote (37951M) (Ohmeda P/N 0220-0091-300)
CAUTION w Do not use any Loctite products to seal the threads (or products which contain Meth-
acrylate Ester as an active ingredient).
The torque range for installing adapters/probes and fittings is 4.0 ft-lb (5.4 N-m) minimum to 10.0 ft-lb (13.6
N-m) maximum.
Adapters/probes and fittings which are not keyed for specific orientation, should be torqued to approxi-
mately 6.0 ft-lb (8.1 N-m).
Adapters/probes and fittings that are keyed to specific orientation, must be torqued initially to 4.0 ft-lbs.
Additional torque is applied only until orientation is correct.
