1.2 Warnings

This service manual contains service, maintenance and parts information on all models of the Push-To-Set TM Continuous

Vacuum Regulator.

After patient use, regulators may be contaminated. Handle in accordance with your hospital’s infection control policy.

North American

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.

International

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.

2.1 North American (ANSI) Vacuum

Regulators

Note: Part numbers given are for PTS-CVR without fi ttings or adapters.

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

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

1.3 Cautions

Do not lubricate any internal components of the regulator module.

Do not use any Loctite® products to seal the fi tting 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 Overfl ow Safety Trap and suction fi lter should be attached prior to its use. Aspirate in the regulator will impair the operation. The use of the Overfl ow Safety

Trap and suction fi lter 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 disassembly, perform the Service Check-out Procedure.

3/Specifi cations

3.1 Description

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

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.

The PTS-CVR 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.

During use, as the fl ow requirement increases, the valve automatically opens to maintain suction at the preset level.

Conversely, when the fl ow 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.

There are several models of the PTS-CVR. 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 PTS-CVR models include a vacuum relief valve to limit maximum suction.

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

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 fi tting port. The regulator module is bypassed and full-line vacuum is provided.

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.

5/Cleaning & Sterilization

5.1 Cleaning 5.1.4 Disinfection

WARNING: After patient use, regulators may be contaminated. Handle in accordance with your hospital’s infection control policy.

Should misuse occur resulting in accidental fl ooding of the regulator, the regulator may be disinfected using Ethylene

Oxide (ETO). After disinfection, follow the service checkout procedures in Section 8.

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.

WARNING: Following disinfection 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 ETO processor’s recommendation for specifi c aeration periods required.

5.1.2 Internal Component Cleaning

CAUTION: Do not steam autoclave or liquid sterilize the PTS-ISU. Severe impairment to the operation of the regulator will result.

CAUTION: Cleaning the gauge may result in damage.

The regulator requires cleaning if it becomes fl ooded with patient fl uid as a result of misuse.

CAUTION: Disinfection with ethylene oxide mixtures may cause crazing (minute superfi cial cracking) of some plastic parts.

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.

3. Dry all components with a lint free cloth before assembly.

Dry internal passages using vac fl ow or compressed air.

5.1.3 Cold Flush Procedure

CAUTION: Do not cold fl ush digital unit

If desired, the vacuum regulator can be cold-fl ushed as part of a cleaning or disinfecting procedure. Set up a collection canister or liner between the vacuum source and the adapter/ probe port of the vacuum regulator to receive the fl ush solution. Suction through the vacuum regulator an adequate amount of cold disinfectant to satisfy the infection control requirements of the hospital. Use only approved cleaning/ fl ushing solutions. Make sure those made from concentrates are newly mixed to ensure effectiveness.

Note: The PTS-ISU should only be disinfected if it is contaminated or maintenance is to be performed.

1. The regulator should be disinfected with the mode selector switch in the |O|O (INT) position.

2. 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. Disinfection is NOT recommended as a frequent procedure.

3. After each disinfection check the condition of the internal fi lters. Replace any shrunken fi lters before returning the regulator to service.

4. Perform Service Checkout Procedure (Section 8).

5.2 Sterilization

Should misuse occur, resulting in accidental fl ooding of the regulator, the regulator may be sterilized using Ethylene

Oxide (ETO). After sterilization, follow the service checkout procedures in Section 8.

Flush both the continuous and intermittent vacuum circuits thoroughly. Adequately aerate both the continuous and intermittent circuits with vacuum fl ow or compressed air until all internal channels, switches, gauge ports and regulating mechanisms are dry. Disassemble to check O-rings for adequate lubricant and fi lters for proper function following any cold fl ush procedure. Perform Service Checkout

Procedure (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 130 o F (54 o C).

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).

9 8700-0006-000 Rev.3

5/Cleaning & Sterilization

CAUTION: Sterilization with ethylene oxide mixtures may cause crazing (minute superfi cial cracking) of some plastic parts. Crazing will be more pronounced when mixtures containing Freon® are used.

Place the regulator in the vertical position and connect to a supply vacuum of 500 mm Hg + 10 mm Hg (67 kPa + 1.3 kPa)

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 fi lter. If the fi lter 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

7.3.2 Vacuum Relief Valve Adjustment

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.

1. Remove the cover.

2. Connect the supply vacuum to the adapter port.

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

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).

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 and

140 mmHg ± 5 mmHg (18.7 kPa ± 0.7 kPa) for units without limiting setscrews.

6. If adjustment is required, grip the vacuum relief valve fi rmly 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.

7.

8. Note: Clockwise rotation will increase the suction level at which the relief valve opens. Counterclockwise rotation will decrease it.

9.

10. 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.

11.

12. 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.

13.

14. 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.

7.3.1 Low Vacuum Limiting Screws

® Loctite is a registered trademark of the Loctite Corporation.

CAUTION: When adjusting the vacuum limiting screws, be sure to adjust them to an equal height.

7.4 Regulator Module

CAUTION: Remove the “Increase” label carefully.

Press fi rmly in place when replacing.

WARNING: If repairing or replacing a regulator module on a Low Vacuum Regulator, you must perform the Suction Level Limit Setting-Low

Models ONLY Procedure. Failure to do this may result in suction exceeding the prescribed level.

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 fi tting 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).

CAUTION: Do not lubricate any internal components of the regulator module.

CAUTION: The cap screws can strip the regulator module housing threads if they are screwed in too tight.

7.4.1 Disassembly

1. Remove timing and fl ow control valves by turning counterclockwise with a fl at-head screwdriver.

2. Replace and/or lubricate o-rings as needed.

9.2 Recommended Maintenance Schedule

Continuous Vacuum Regulators should be kept in use or used on a rotating basis. Unused equipment may tend to deteriorate.

Ohio Medical vacuum regulators function for decades. They are proven to provide trouble-free service with minimum care.

Maintenance of the vacuum piping system is as important as maintenance of the suction equipment. The use of Collection

Bottles with reliable shut-off valves, Overfl ow Safety Trap assemblies and disposable suction fi lters will protect the regulator and piping system. The fl ow rate at the wall outlet should be checked on a yearly basis and suitable cleaning of the outlets should be performed. The fl ow rate measurement should meet local standards.

Routine maintenance and inspection are important to the performance of suction equipment. The following is a recommended list for care of suction equipment after each patient use.

We recommend the following to determine the maintenance schedule appropriate for each facility:

1. Periodically (as required, but no less than annually) inspect the overall condition of the vacuum regulator.
