Overview
This document includes cleaning instructions for each item included in the Nox T3 and Nox A1 System.
All reusable components should be cleaned between patient uses.
Nox Sleep Recording Device (Nox A1 and Nox T3), Nox Abdomen Cable, Nox A1 EEG Head Cable, Nox Snap On Cables and Carry Cases.
Materials/equipment:
- Endozime® AW Plus
- Lint-free cloths
- Gloves
- Soft bristle nylon brush (i.e. electrode brush, toothbrush, or nail brush)
- PDI Sani-Cloth Plus Germicidal Disposable Cloth or equivalent validated disinfectant*
Cleaning/DISINFECTING procedure:
- Prepare a solution with the Endozime® AW Plus hospital grade cleaner
- Follow the instructions accompanying the hospital grade cleaner
- Dampen a lint-free cloth with the solution
- Do not pour or spray any liquids on the Nox Recorder
- Do not allow any liquids to enter any openings on the Nox Recorder
- Do not immerse the cables in liquid
- Avoid contact of the cleaning solution to cable/electrode connectors
- Wipe all surface areas thoroughly to remove all visible soil and contaminants. Wipe the component for at least 2 minutes. Use a soft bristle nylon brush if necessary.
- Visually inspect the cleaned components to ensure no soil remains. Pay good attention to all junctions and details. Repeat steps 2 and 3 if necessary.
- Allow components to air dry completely before disinfection (minimum of 3 minutes)
- For disinfection, take a new wipe of PDI Sani-Cloth Plus Germicidal Disposable Cloth or equivalent validated disinfectant*
- Wipe all surface areas of the component with the disinfectant for at least three minutes
- If other disinfection materials are used than PDI Sani-Cloth Plus Germicidal Disposable Cloth make sure:
- they are safe to use on metals and plastics
- to read the instructions from the manufacturer regarding required contact time of the solution to provide sufficient disinfection
- If other disinfection materials are used than PDI Sani-Cloth Plus Germicidal Disposable Cloth make sure:
- Allow components to air dry completely before next use (minimum 1 minute)
- Visually inspect the components under adequate lighting conditions (and magnification if needed) to confirm that the cleaning/disinfection process has not damaged components. Inspect for surface wear, discoloration, corrosion, or cracking. **
If necessary, the clips on the Nox A1s recorder can be removed before cleaning. The cleaning process described above also applies for the clips. If the clips are visibly contaminated, they should be replaced.
Nox A1 EEG 5 Lead Gold Electrode Cable
Clean the gold cup electrodes immediately after use.
Materials/equipment:
- Lint-free cloths
- Gloves
- Soft bristle brush (i.e. electrode brush, toothbrush, or nailbrush)
- Q-Tip
- Bowl or a cup
- PDI Sani-Cloth Plus Germicidal Disposable Cloth or equivalent validated disinfectant*
- Warm water
Cleaning process:
- Soak the electrodes (not the connectors) in warm water (55-65°C/131-149°F) for minimum 5 minutes to soften dried electrode paste
- Do not soak the electrodes in alcohol or bleach
- Do not use an abrasive-based cleaner on the electrodes, as it can damage the gold plating
- Use a lint- free cloth, soft bristle brush or a Q-tip to remove all traces of electrode paste from the electrodes
- Only apply light force when cleaning gold plated surfaces. Gold plating is soft and can easily be damaged or scratched when contacted.
- Allow the Gold Cup Electrodes to air dry completely (minimum 3 minutes)
- For disinfection use a fresh wipe of PDI Sani-Cloth Plus Germicidal Disposable Cloth or equivalent validated disinfectant*. Wipe the electrodes and leads gently for 3 minutes
- Do not rub the electrodes with the disinfection wipes
- Do not disinfect the electrodes with bleach
- If other disinfection wipes are used make sure:
- they are safe to use on gold plating, metals, and plastics
- to read the instructions from the manufacturer regarding required contact time of the solution to provide sufficient disinfection
- Allow the Gold Cup Electrodes to air dry completely (minimum 1 minute)
- Visually inspect the Gold Cup Electrodes under adequate lighting conditions (and magnification if needed) to confirm that the cleaning/disinfection process has not damaged components. Inspect for surface wear, discoloration, corrosion, or cracking. **
* PDI Sani-Cloth Plus Germicidal Disposable Cloth are Environmental Protection Agency (EPA) registered product for disinfection of medical devices in the United States of America. For Europe or Rest of the World equivalent validated disinfectant may be used if they are safe to use on gold plating, metals, and plastics. Similar disinfection wipes from PDI are available in Europe and are recommended to use with the Nox Sleep System: Super Sani-Cloth Plus disinfection wipes.
** If any component damage occurs during cleaning process, contact Nox Medical immediately at support@noxmedical.com. Do not attempt to use the Nox Sleep System until the device has been inspected and repaired by authorized Nox Medical personnel.
WristOx2, Model 3150
Wipe the device with a soft cloth dampened with a 10% bleach/90% water solution (household bleach [containing less than 10% sodium hypochlorite]). Do not use undiluted bleach or any cleaning solution other than those recommended here, as permanent damage could result. Dry with a soft cloth, or allow to air dry. Clean once per week or more frequently if handled by multiple users.
CAUTION: Do not place the WristOx2, Model 3150, in liquid or clean it with agents containing ammonium chloride or isopropyl alcohol
WristOx2 Soft Sensor
- Unplug the sensor from the pulse oximeter before cleaning.
- Do not sterilize in an autoclave or immerse the sensor in liquid of any kind. Do not pour or spray any liquids onto the sensor.
- Do not use caustic or abrasive cleaning agents on the sensor. Do not use cleaning agents containing ammonium chloride. Use of these chemicals may shorten the life of the product.
- To clean the sensor, wipe all patient contact surfaces with a soft cloth dampened with a mild detergent, isopropyl alcohol, or a 10% bleach/90% water solution (household bleach [containing less than 10% sodium hypochlorite]).
- Allow the sensor to dry thoroughly before using.
Note: To minimize cable deterioration when cleaning the cable, gently wipe away from the plug end towards the sensor end.
Cautions:
- Do not use a damaged sensor. If the sensor is damaged, discontinue use immediately.
- Do not sterilize, autoclave or immerse in liquid of any kind.
- Do not use caustic or abrasive cleaning agents on the sensor.
- Follow local governing ordinances and recycling instructions regarding disposal or recycling of the sensor and any components.
- A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor.
- As with all medical equipment, carefully route patient cables and connections to reduce the possibility of entanglement or strangulation.
- Refer to the pulse oximeter operator´s manual for additional warnings and cautions.
- Factors that may degrade pulse oximeter performance include the following:
- Excessive ambient light
- Excessive motion
- Electrosurgical interference
- Moisture in the sensor
- Improperly applied sensor
- Carboxyhemoglobin
- Methemoglobin
- Blood flow restrictors (arterial catheters, blood pressure cuffs, infusion lines, etc)
- Incorrect sensor type
- Poor pulse quality
- Venous pulsations
- Anemia or low hemoglobin concentrations
- Cardiovascular dyes
- Dysfunctional hemoglobin
- Artificial nails or fingernail polish
- Residue (e.g., dried blood, dirt, grease, oil) in the light path
SPO2 3150 Wrist Band
The wristband is designed for single-patient use. If it needs to be cleaned, hand wash with a mild detergent (see note) in cool water (30 °C/86 °F). Allow to air dry. Do not machine wash or dry. The wrist band will shrink if placed in a dryer.
NOTE: Mild detergents, such as hand and dish washing liquid detergents, dissolve dirt and grease. To clean washable surfaces, use in a solution of warm water.
CAUTION: Use a detergent that is safe for skin and washable surfaces. Most detergents can be high sudsing, so use sparingly. Wipe with a damp, detergent free cloth to remove residue.
CAUTION: After cleaning the single-patient use wristband, it should only be applied to the same patient; do not apply it to a different patient.
