Shranjevalni prostor z nadzorovanim okoljem za pripravljene termolabilne endoskope
Predlagani standard določa zahteve glede zmogljivosti prostorov za shranjevanje in sušenje občutljivih endoskopov (SCHE) po samodejni ali ročni pripravi za ponovno uporabo. Shranjevalni prostori zagotavljajo nadzorovano okolje za shranjevanje endoskopov in, kadar je to potrebno, njihovo sušenje, vključno z endoskopskimi kanali. Nadzorovano okolje zagotavlja, da se med shranjevanjem ne poslabša mikrobna kakovost endoskopa. Faza sušenja je namenjena kot dopolnilo, če je to potrebno, vsakemu sušenju, ki je del samodejnega ali ročnega cikla priprave na ponovno uporabo. Prostor ni namenjen za nobeno funkcijo čiščenja oziroma dezinfekcije. OPOMBA 1: Uporaba shranjevalnega prostora lahko dovoljuje varno uporabo endoskopa dlje časa po pripravi za ponovno uporabo in lahko izboljša razpoložljivost za uporabo v sili. OPOMBA 2: Temeljito sušenje endoskopa v pralno-dezinfekcijskem pripomočku lahko zahteva daljši čas cikla; uporaba shranjevalnega prostora pa lahko poveča pretok endoskopov.

Overview - EN 16442:2015 in brief
EN 16442:2015 is the CEN European Standard that specifies performance and testing requirements for controlled environment storage cabinets for processed thermolabile endoscopes. It covers cabinets that store - and where required, dry - endoscopes after manual or automated reprocessing. The objective is to ensure that storage does not allow deterioration of the endoscope’s microbiological quality; the standard explicitly does not cover cleaning or disinfection functions and notes that these cabinets are not considered medical devices.
Key topics and technical requirements
- Controlled environment and storage: Cabinets must maintain a controlled atmosphere so microbiological quality of endoscopes is not degraded during the storage cycle (see Clause 4).
- Drying function: Optional drying phases and controlled drying temperature bands are specified to supplement drying from washer-disinfectors.
- Channel flushing and aeration: Cabinets covered by EN 16442 flush endoscope channels and external surfaces with air; ESC (endoscope storage cabinet) connectors and channel aeration systems are addressed.
- Air quality and filtration: Requirements and tests for air changes, filtration and airborne microbial contamination (see Clause 6 and Annex C).
- Mechanical, instrumentation and monitoring: Materials, design, temperature/humidity/pressure indicators, cycle/fault indicators, and traceability requirements (Clauses 5 and 8).
- Risk analysis and conformity testing: Manufacturers must perform risk analysis (e.g., cross-contamination, ingress during loading) and confirm performance by tests for drying, contamination of cabinet surfaces, thermometric testing, overpressure, channel aeration and air quality (Clause 6, Annexes B, E).
- Documentation and labelling: Detailed information to be supplied with the cabinet, marking and installation/operational instructions (Clause 8).
Practical applications - who uses this standard
- Endoscope storage cabinet manufacturers: to design and verify compliant products.
- Hospital procurement and clinical engineering: to specify, evaluate and accept cabinets for endoscope reprocessing workflows.
- Infection prevention and control teams / CSSD: to implement storage practices that preserve microbiological quality and support throughput.
- Biomedical and facilities engineers: for installation, validation and maintenance (testing, traceability and monitoring).
- Regulatory and compliance personnel: to align documentation and risk assessments with European normative expectations.

The article discusses the proposed standard for controlled environment storage cabinets used to store and dry heat-sensitive endoscopes after they have been reprocessed. These cabinets are specifically designed to provide a controlled environment to prevent any deterioration of the endoscope's microbial quality during storage. The drying stage in the cabinet is meant to supplement any drying that may have been done during the reprocessing cycle. It is important to note that the cabinet does not have any cleaning or disinfection functions. The use of a storage cabinet may allow for the safe use of the endoscope for a longer period after reprocessing and improve availability for emergency situations. Additionally, using a drying-storage cabinet can enhance the throughput of endoscopes by reducing the cycle time required for thorough drying in a washer-disinfector.
