What This Guide Helps With

Use when fluid, aerosol, or abnormal odor is observed around the Neptune waste path, canister interfaces, tubing, ports, or docking connections.

Step-by-Step Troubleshooting

1. Protect the Patient and Personnel Immediately

If fluid, aerosol, or waste odor is escaping from the Neptune during clinical use, stop relying on the affected waste path and provide alternate verified suction as needed.

Treat all leaked material and contaminated surfaces as potentially biohazardous. Use required PPE and follow facility exposure and spill procedures.

Expected outcome: Patient care continues safely and personnel are protected from further exposure. A device actively leaking contaminated waste should be removed from use.

2. Identify the Location and Nature of the Leak

Without opening the waste system, determine whether the problem appears to originate from:

• External suction tubing
• A manifold or disposable
• A port connection
• An external seal or connection
• The rover exterior
• A docking interface
• The smoke or filtration path

Note whether the problem involves visible fluid, mist or aerosol, odor only, or a combination.

Expected outcome: The likely external source area is identified without unnecessary exposure.

3. Inspect External Tubing and Accessories

Inspect all accessible tubing and disposable components for:

• Cracks
• Punctures
• Loose fittings
• Improper seating
• Disconnected tubing
• Damaged caps or connectors
• Obvious overfilling or contamination

Replace damaged disposable components rather than attempting repair.

Expected outcome: External suction tubing and disposables are intact and securely connected. If replacement of a damaged disposable eliminates the leak, continue to functional verification.

4. Verify Manifold and Port Seating

Using appropriate PPE, verify that manifolds and external waste-path connections are fully engaged.

Do not force connections or bypass locking or recognition features.

Expected outcome: Each external connection is fully seated and secure without visible leakage.

5. Inspect for External Contamination

Inspect the rover exterior, port area, tubing supports, filter area, and accessible docking surfaces for residual waste from an earlier spill or disconnected accessory.

Clean and disinfect only according to approved procedures.

Expected outcome: Residual contamination is removed, allowing determination of whether an active leak is still present.

6. Check Smoke and Filter Components When Odor Is Reported

If odor or aerosol is associated with smoke evacuation, inspect the accessible filter installation, smoke tubing, and external connections.

A filter that is damaged, incorrectly seated, or contaminated should be replaced according to approved practice.

Expected outcome: The smoke path is correctly assembled with intact compatible components and no external leakage.

7. Observe for Leakage During a Controlled Test

After any external correction, perform a controlled nonclinical operational test using an appropriate setup.

Observe externally for fluid leakage, aerosol release, abnormal odor, or unstable connections. Do not intentionally expose personnel to aerosolized waste.

Expected outcome: No fluid, aerosol, or abnormal odor escapes from the system. If the waste path remains dry and secure during testing, troubleshooting can stop after appropriate decontamination and verification.

8. Inspect the Docking Area If the Leak Occurred During Transfer

If the report occurred during docking or waste transfer, inspect accessible rover and docking interfaces for contamination, damaged external connections, or evidence of incomplete engagement.

Do not initiate another transfer cycle if an active leak is visible.

Expected outcome: No external defect or active contamination remains. If the transfer interface cannot be verified as leak-free, keep the equipment out of service.

9. Remove the Device From Service for Any Uncontained Leak

If fluid appears to originate from inside the rover, aerosol continues despite correct external components, odor persists from the internal waste path, or the leak source cannot be confidently identified, stop troubleshooting.

Expected outcome: The Neptune is isolated from clinical use and handled as contaminated equipment requiring qualified evaluation.

If the Problem Persists

Common external causes such as damaged tubing, loose connections, improperly seated disposables, residual contamination, and filter installation problems have been ruled out.

The remaining problem may involve internal waste tubing, seals, reservoirs, valves, pumps, filtration components, docking hardware, or another service-level waste-path condition.

The device should be:

• Removed from service.
• Labeled Out of Service.
• Isolated and handled according to facility biohazard and decontamination requirements.
• Sent for repair or bench evaluation.
• Evaluated using appropriate Stryker documentation and approved test equipment.
• Repaired only by qualified personnel using appropriate contamination precautions.

After repair, the waste path must be verified leak-free and all affected suction, smoke-evacuation, and waste-transfer functions tested before clinical return. Knowing when to stop external troubleshooting is proper troubleshooting.

Clinical Use Tip

Any unexplained release of surgical waste, aerosol, or waste-path odor should be treated as a containment failure until proven otherwise.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"OR staff reported fluid leaking around the Neptune suction manifold connection during setup."

Cause

What was observed during troubleshooting.

Example:
"Clinical Engineering found the disposable suction manifold cracked at the external connection and leaking when suction was applied."

Resolution

What action was taken.

Example:
"Replaced the damaged disposable using appropriate PPE, cleaned the affected external surfaces, verified the waste path remained leak-free during functional testing, and returned the unit to service."

Helpful Details to Include (If Known)

• Exact location of observed leakage
• Fluid, aerosol, odor, or combination
• Whether the issue occurred during suction or docking
• Manifold and tubing condition
• Filter condition when applicable
• Evidence of residual contamination
• PPE and decontamination actions
• Known-good disposable substitution
• Results of leak observation after correction
• Final device status

Final Thought

Waste-path leakage requires immediate attention to patient continuity, personnel exposure, and contamination control. Rule out damaged external components and poor connections first, but remove the Neptune from service whenever containment cannot be confidently restored and verified.

That is successful troubleshooting.
