| Hygiene & Safety |
Closed system with hydrophobic filter, hermetically sealed bag.
No direct contact with contaminated liquid.
|
Opening and emptying of the canister required; increased risk of splashes,
aerosols, and contamination.
|
| Handling Contaminated Liquid |
No transport of open liquids – the bag remains sealed from use to disposal.
|
Canisters must be transported, opened, and emptied for emptying and rinsing.
|
| Disposal |
Disposal as Category A household waste, without special infrastructure.
|
Partially hazardous waste, additional disposal effort, and higher process costs.
|
| Filter & Subsequent Costs |
Integrated, self-closing filter – no separate filter changes.
|
Regular, expensive filter changes and seal changes necessary.
|
| Cleaning & Disinfection |
Only wipe disinfection of the holder is necessary; the disposable bag itself is not reprocessed.
|
Complete reprocessing necessary: emptying, rinsing, cleaning, disinfection, drying, documentation.
|
| Infrastructure & Rinsing Systems |
No additional rinsing systems or sluice sinks required.
|
For occupational safety reasons, special sluice sinks and rinsing systems are required for reusable canisters.
|
| Acquisition Costs |
No investment in rinsing machines, washer-disinfectors, or special reprocessing equipment.
|
High acquisition costs for reusable canisters, cleaning equipment, rinsing systems, and infrastructure.
|
| Service Life & Material |
Disposable system – always new, no material fatigue or loss of quality.
|
Short service life due to repeated autoclaving: clouding, embrittlement, material wear.
|
| Aesthetics & Impression |
Bags and components always appear clean, transparent, and professional.
|
Reusable canisters become dull, discolored, and visually "used" over time, despite cleaning.
|
| Staff Burden & Appreciation |
No opening, no emptying, no direct contact with blood and secretions –
clear relief and appreciation for staff.
|
Staff must regularly open, empty, and clean contaminated canisters – physically
and psychologically burdensome.
