1.2 Warnings

The Pre-Use Checkout Procedure must be performed before using this equipment on each patient. If the regulator fails any part of the Pre-Use Checkout Procedure, it must be removed from service and repaired by qualified service personnel.

Connect the Vacuum Regulator to the vacuum source only. Connection to pressure sources even momentarily could injure the patient or operator and damage the equipment.

Always connect the regulator to the vacuum source and check its operation before attaching the patient connection.

The fitting port of the regulator must be occluded when setting the prescribed suction level. This prevents the patient from receiving higher than required suction levels.

Do not use this device in the presence of flammable anesthetics. Static charges may not dissipate and a possible explosion hazard exists in the presents of these agents.

After patient use, regulators may be contaminated.

Handle in accordance with your hospital’s infection control policy.

Clean and sterilize all suction equipment before shipment or service to ensure transportation personnel and/or service personnel are not exposed to any hazardous contamination.

Clean and sterilize all suction equipment if contaminated before disassembly, to ensure service personnel are not exposed to hazardous contamination.

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. Aerate parts for 8 hours at 130oF (54oC).

If the Vacuum Regulator is repaired or disassembled in any manner, the Service Checkout Procedure must be performed before using the equipment on the patient.

The 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.

Precautions/1

1.3 Cautions

Do not lubricate any internal components of the regulator module.

Do not use any Loctite® products to seal the fitting and adapter port threads (or products which contain Methacrylate Ester as an active ingredient).

Only competent individuals trained in the repair of this equipment should attempt to service it.

To help prevent aspirate from entering the regulator, as a result of misuse, an Overflow Safety Trap and suction filter should be attached prior to its use. Aspirate in the regulator will impair the operation. The use of the Overflow Safety Trap and suction filter will help prevent this and extend the life of the suction equipment.

Use of lubricants other than recommended may degrade plastic or rubber components.

Prior to placing the unit back into service after repair or dissassembly , perform the Service Check-out Procedure.

Description and Specification/3

3.1 Description

WARNING



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 V acuum 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 maximum 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 automatically 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.

Operation/4

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



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 regu-

lator's fitting port or Overflow Safety Trap with the appropriate suction filter and 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 Ohio Medical High Flow Suction Filter should be used between the collection container and regulator to prevent contamination of the regulator. Hospital-supplied suction tubing must be used between the catheter and the collection bottle. Recommended minimum inside diameter is 0.25 in (6 mm).

4.2 Attaching the Safety Trap

CAUTION



To help prevent aspirate from entering the regulator, wall outlet and pipeline system as a result of misuse, an Overflow Safety Trap should be attached prior to its use. Aspirate in the regulator, wall outlet and pipeline system may impair their operation. The use of the Overflow Safety Trap and suction filter will help prevent this and extend the life of suction equipment.

Standard fitting

1. Raise the sleeve and insert the trap into the regulator fitting.

2. Turn the trap clockwise about one and a half turns to engage the threads. The trap does not need to be screwed tight; an O-ring in the regulator fitting provides a vacuum seal. The trap should rotate freely to allow the desired tubing positioning.

3. Lower sleeve to lock trap in position.

DISS fitting

1. Insert trap into the regulator fitting. Situate the tubing in the desired position.

2. Turn the DISS wing nut clockwise to engage threads and tighten (there is no O-ring, so the vacuum seal depends on a tight connection).

Cleaning and Sterilization/5

5.1 Cleaning



WARNING 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 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

Should misuse occur, resulting in accidental flooding of the regulator, the regulator may be sterilized using Ethylene Oxide (ETO). After sterilization, follow the service checkout procedures in Section 8.

WARNING



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. Aerate parts for 8 hours at 130oF (54oC).

CAUTION



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



Sterilization with ethylene oxide mixtures may cause crazing (minute superficial cracking) 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 performed.

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.

7.3Suction Level Limit Setting-Low Models ONLY

WARNING



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/19 kPa (± 10 mmHg/1.0 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



When adjusting the vacuum limiting

screws, be sure to adjust them to an equal height.

CAUTION



Remove the “Increase” label careful-

ly. Press firmly in place when replacing.

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.

3. Connect the vacuum supply to the adapter port and occlude the fitting port.

4. Be certain that the screws remain at an equal height by adjusting both low vacuum limiting screws the same amount and in the same direction. Adjust the screws to supply a maximum vacuum of 150 mm Hg (20 kPa) and not less than 130 mm Hg (17 kPa).

7.3.2 Vacuum Relief Valve Adjustment

1. Remove the cover.

2. Connect the supply vacuum to the adapter port.

3. Turn the mode selector switch to I/ON.

4. Occlude the fitting port.

5. Slowly pull the regulator module away from the base. Note the suction level at which the relief valve opens. The relief valve should open at 165 mmHg ± 15 mmHg (22 kPa ± 2 kPa) on units with limiting setscrews and140 mmHg ± 5 mmHg (18.7 kPa ± 0.7 kPa) for units without limiting 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



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



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 following lubricants:

Dow® 111 (Ohio Medical P/N 6700-0074-200) Ball Vac Kote (37951M) (Ohio Medical P/N 0220-0091-

300)

CAUTION



Do not use any Loctite products to seal the threads (or products which contain Methacrylate 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 Nm) maximum.

Adapters/probes and fittings which are not keyed for specific orientation, should be torqued to approximately

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.
