INTENDED USE

Amvex Vacuum Regulators are intended to regulate a supplied vacuum pressure to the user’s desired vacuum level. A gauge shows the value of the regulated vacuum, which is adjustable via a regulating knob.

Vacuum Regulator Model Gauge Range Gauge Accuracy
Analog Digital
Continuous 0 – 200 mmHg +/- 3% F.S.
0 – 300 mmHg +/- 3% F.S. +/- 1% F.S. at 22ºC
Pediatric Continuous 0 – 160 mmHg +/- 3% F.S.
Neonatal Continuous 0 – 100 mmHg +/- 3% F.S.
High 0 – 170 mmHg +/- 3% F.S.

Please note: F.S. = Full Scale

Flow Rates Standard Pediatric
Continuous 0 – 80 L/min 0 – 40 L/min

OPERATING INSTRUCTIONS

  • ATTENTION: The operating and storage temperature for the regulator should reflect typical environmental conditions of a medical facility environment.
  • WARNING: DO NOT change, alter or modify the intended use of the product.

Other Equipment Needed:
¼” (0.635cm) Suction tubing, Suction filter or overflow safety trap, collection canister.

Equipment Setup:

  • Depending on the desired location of the regulator, connect the vacuum adapter directly to the wall outlet, or connect one end of an Amvex vacuum hose assembly to the supply port of the suction regulator and the other end to the vacuum source (i.e. wall outlet).
  • Use ¼” suction tubing, between the patient and patient port of the collection canister, as well as between the outlet port of the Vacuum Regulator and canister. A high-flow suction filter and/or an overflow safety trap between the regulator and the collection canister should be used to prevent occlusion or contamination of the regulator, wall outlet or pipeline system.

Selecting the Mode:

AMVEX-VR-C-Vacuum-Regulator-fig- \(4\)

  • NOTE: REG mode is only available on the 3 mode models
  • ATTENTION: When the selector is set between REG and OFF, the patient will receive a full wall vacuum.

Battery Low Indicator (Digital Models Only):

NOTE:
When a battery icon appears on the gauge it indicates that the battery is low. Please take the unit out of service immediately and contact an Ohio Medical Customer Service Representative for battery replacement. If the low battery condition is not addressed and the battery becomes fully depleted, the gauge will not show any readout including the low battery icon or gauge pressure. If the gauge were to go blank during suctioning, the unit would continue to suction and the intermittent feature would continue to operate. Once completing that procedure, it is important to immediately take the unit out of service and contact the Amvex/Ohio Medical Customer Service Representative for battery replacement.

Procedures Prior to Use List:

WARNING:
The following tests are recommended prior to use on each patient. If the Vacuum Regulator does not pass one or more of the following tests, it should be evaluated, repaired and/or replaced by a qualified individual.

The following tests must be done with a minimum supply vacuum of -53 kPa(-400 mmHg):

  1. Move the selector switch to the “OFF” position. Turn the regulator knob one complete turn in the clockwise direction. Kink the vacuum tubing to block the outlet. There should be no movement of the gauge needle (or in case of a digital gauge, no change in the display).

  2. Move the selector switch to the “REG” position. Turn the regulator knob fully in the counter-clockwise direction. Kink the vacuum tubing; again, there should be no movement of the gauge needle (or in case of a digital gauge, no change in the display).

  3. Kink vacuum tubing.
    Regulator Setting:

    • Standard: Increase the vacuum to -12 kPa (-90 mmHg)
    • Pediatric & Neonatal: Increase the vacuum to -5 kPa (-40 mmHg)
  4. Open and close the kinked vacuum tubing slowly to reach various vacuum rates. Ensure that the level of vacuum is maintained consistently when the vacuum tubing is kinked.
    Standard Continuous and High Vacuum:
    Follow the steps below based on the mode type
    2 Mode:

  5. Decrease the vacuum to zero and move the selector switch to the “OFF” position.
    3 Mode:

  6. Move the selector switch to the “FULL” position. Kink the vacuum tubing and ensure that the vacuum gauge is reflecting the maximum suction available.

    • 5b. Move the selector switch to the “REG” position.
    • 5c. Decrease the vacuum to zero and move the selector switch to the “OFF” position.
      Pediatric & Neonatal Continuous: 
  7. In the “REG” position, kink the vacuum tubing and turn the regulator control knob fully in the clockwise direction to ensure that the vacuum level does not go over -21 kPa (-160 mmHg) for Pediatric and -13 kPa (-100mmHg) for Neonatal.
    NOTE: This feature is only present in the Pediatric and Neonatal models.

  8. Decrease the vacuum level to zero and move the selector switch to the “OFF” position.

Setup for Patient use:
Setting the Level of Vacuum for Patient Use:

  1. Amvex recommends that the Procedures Prior To Use list be completed

  2. Move the selector switch to the “REG” position.

  3. Kink the vacuum tubing.

  4. Set the required vacuum level.
    WARNING: The vacuum tubing must be kinked to ensure that the patient is not exposed to a higher level of vacuum than what is required.

  5. Move the selector switch to the “OFF” position.

  6. Attach the vacuum tubing to the vacuum canister.

CLEANING INSTRUCTIONS

The following internal cleaning procedure may be followed if your unit becomes contaminated.

  1. Connect the supply port of the Vacuum Regulator to the patient port of a collection canister.
  2. Attach the vacuum port of the collection canister to a vacuum source.
  3. Connect a hose from the patient port of the Regulator to be cleaned and place the other end into a container containing 100cc of a cold sterilant.
  4. Fully increase the regulating knob of the vacuum regulator (clockwise).
  5. Turn on the Vacuum Regulator to the “REG” mode. Wait until all of the cold sterilant is passed through the regulator.
  6. Repeat steps 3,4 & 5 for all modes of the Vacuum Regulator.
  7. Repeat steps 3,4 & 5 using 100cc of isopropyl alcohol to purge the Vacuum Regulator of the sterilant.
  8. The Regulator should run for 30 sec. in each mode with its patient port open to the atmosphere to dry internal parts.

CAUTION:

  • Ethylene oxide is not recommended. Sterilization using an ethylene mixture may cause small surface cracks to some of the plastic parts that may not be apparent to the user.
  • Do not steam autoclave, immerse in liquid or gas sterilize the Vacuum Regulators. This may damage the unit.
  • If the Vacuum Regulator becomes contaminated internally, the warranty is voided. Do not send the Vacuum Regulator back to the manufacturer. Follow your facility’s procedures for handling contaminated products.

RECOMMENDED MAINTENANCE

The following are recommended maintenance steps that should be taken after each patient:

  1. Clean the exterior of the Vacuum Regulator with a solution of a diluted mild detergent.
  2. Make sure all secondary apparatus such as canisters and tubing are thoroughly cleaned.
  3. Inspect the bacteria filter. If it has been contaminated replace it with a new one.
  4. Inspect the overflow safety trap to make sure it is free of any restrictions.
