8700-0006-000 Rev.8 (10/2014)


3.1 Description

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.

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.

Some models operate in a regulated or non-regulated MAX mode. Others operate only in the regulated mode.

In the non-regulated MAX mode, the vacuum source is connected directly to the fitting/patient port. The regulator module is bypassed and full-line vacuum is provided.

In the regulated 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.

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.

4/Cleaning, Disinfection and Sterilization

4.1 Cleaning and Disinfection

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

CAUTION: Suctioned fluids drawn into a vacuum regulator do not stop in the regulator. They proceed through it into the wall outlet and pipeline system. Failure to clean and disinfect the wall outlet and pipeline system may result in damage to this equipment.

4.1.1 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 and/or an approved cleaning solution.

4.1.1.1 Approved Cleaning Solutions

• Sodium Hypochlorite 0.5% (Bleach): Mixture of 13 fl. oz. of bleach to 1 gallon (128 fl. oz.) tap water

• Isopropyl Alcohol 70%

• Hydrogen Peroxide 3%

• Cavicide

®

Ready to use full strength

4.2 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 (Section 7 Service Checkout Procedure).

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°F

(54°C). Follow your hospital sterilization procedure.

CAUTION: Do not steam autoclave or liquid sterilize the intermittent 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.

6.3 Suction Level Limit Setting

(PED/NEO/C.A.S.S. 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.

6.3.1 Vacuum Relief Valve Adjustment

1. Remove the cover (see Section 6.2.1 Disassembly).

2. Connect the supply vacuum to the adapter/probe port.

3. Connect an external vacuum test gauge to the patient port.

4. Move the mode selector switch to | (ON).

5. Slowly rotate the regulator module to increase the vacuum level. Note the suction level at which the relief valve opens. The relief valve should open at

140 mmHg ± 5 mmHg (18.7 kPa ± 0.7 kPa) on the external test gauge.

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.

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

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.

8. Re-attach the cover (see Section 6.2.2 Assembly).

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.

6.3.2 Vacuum Limiting Set Screw

Adjustment (PED and NEO Units

8/Maintenance

8.1 General Maintenance of Suction Equipment

WARNING: 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.

WARNING: If the unit has been contaminated, clean and disinfect all suction equipment before disassembly.

PTS-CVR should be kept in use or used on a rotating basis. Internal parts of unused equipment may tend to deteriorate.

Maintenance of the vacuum piping system is as important as maintenance of the suction equipment. The use of collection canisters with reliable shut-off valves, overflow safety trap assemblies and disposable suction filters will protect the regulator, wall outlet, and piping system. The flow rate at the wall outlet should be checked on a yearly basis and suitable cleaning of the outlets should be performed as needed. The flow rate measurement should meet NFPA

®

99 and/or ISO

® 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.

1. Keep connecting tubing, fittings and adapters/probes clean.

2. Wipe all exterior surfaces with a solution of water and mild detergent or approved cleaning solutions.

3. Perform a careful visual inspection of the vacuum regulator.

4. Check that the high flow disposable suction filter is clean and in good condition.

5. Check that all tubing is in good condition and connected securely to the correct ports.

6. Check the floats in the Overflow Protection Device and collection canister for correct operation.

7. Perform the Pre-use Checkout Procedure.

8.2 Recommended Maintenance Schedule

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. Test gauge accuracy (Section 7.3 Gauge Test) and perform the pre-use checkout procedure (See PTS-CVR Instructions for Use for the Pre-use Checkout Procedure). If the regulator does not pass, refer to troubleshooting (Section 5
