1.1. Intended use

The endoscope is a sterile, single-use, flexible gastroscope intended to be used for endoscopic

access to and examination of the upper gastrointestinal anatomy� The endoscope is intended

to provide visualization via a compatible Ambu displaying unit and to be used with

endotherapy accessories and other ancillary equipment�

1.2. Intended patient population

The endoscope is intended to be used in adults; this means patients with the age of 18 years

orabove� The endoscope is used in patients with indications in the upper gastrointestinal

anatomy requiring visualization and/or examination with flexible gastroscopy and use of

endotherapy accessories and/or equipment�

1.3. Contraindications

No known contraindications�

1.4. Clinical benefits

The endoscope, when used with the compatible displaying unit, enables visualization,

examination, and endoscopic intervention of key anatomical structures in the upper

gastrointestinal (GI) tract, particularly esophagus, gastroesophageal junction, stomach,

pylorus, duodenal bulb, and descending duodenum� High-definition imaging technology will

enable endoscopists to view mucosal and vascular structures� The risk of endoscope-related

patient cross-contamination is eliminated compared to reusable endoscopes, as the

endoscope is a sterile single-use medical device�

1.5. Warnings and cautions

WARNINGS

1� For single use only� Do not reuse, reprocess or resterilize as these processes may leave

harmful residues or cause malfunction of the endoscope� Reuse of the endoscope may

cause cross-contamination potentially leading to infections�

2� Confirm that the opening of the insufflation/rinsing valve is not blocked or covered,

and that the insufflation pressure does not exceed the given limit� If gas is excessively

insufflated into the patient this may result in patient pain, bleeding, perforation and/or

gas embolism�

3� Prior to use always perform an inspection and functionality check according to sections

3�1 and 3�4� Do not use the device if the endoscope or its packaging is damaged in any

way or if the functionality check fails, as this can lead to patient injury or infection�

4

en

4� Patient leakage currents may be additive, when using energised endotherapy accessories�

Do not use energised endotherapy accessories which are not classified as "type CF" or

"type BF" applied parts according to IEC60601-1, as that could lead to too high patient

leakage current�

5� Do not perform procedures with High Frequency (HF) endotherapy accessories if

flammable or explosive gases are present in the gastrointestinal tract as this may result

in serious injury to the patient�

6� Always observe the live endoscopic image when inserting, withdrawing, or operating

the endoscope� Failure to do so may result in patient injury, bleeding and/or perforation�

7� Ensure that the insufflator is not connected to the auxiliary water inlet as this may

cause over insufflation which can result in patient pain, bleeding, perforation and/or

gas embolism�

8� The distal tip of the endoscope may get warm due to heating from the LEDs� Avoid

long periods of contact between the distal tip of the endoscope and the mucosa as

sustained contact may cause tissue damage�

9� Do not insert or withdraw the endoscope if an endotherapy accessory is protruding

from the distal end of the working channel as this may result in injury to the patient�

10� If the biopsy valve is left uncapped and/or if the biopsy valve is damaged it can reduce

the efficacy of the endoscope's suction functionality, and may leak or spray patient

debris or fluids, posing a risk of infection� When the valve is uncapped, place a piece of

sterile gauze over it to prevent leakage�

11� Always use gauze to pull the endotherapy accessory through the biopsy valve as

patient debris or fluids may leak or spray, posing a risk of infection�

12� During the procedure always wear personal protective equipment (PPE) to protect

against contact with potentially infectious material� Failure to do so may cause

contamination potentially leading to infections�

13� Using HF endotherapy accessories with endoscope may disturb the image on the

displaying unit which may lead to patient injury� To reduce disturbance, try alternative

settings on the HF generator with lower peak voltages�

14� Portable Radio Frequency (RF) communications equipment (including peripherals such

as antenna cables and external antennas) should be used no closer than 30cm (12'') to

any part of the endoscope and the displaying unit, including cables specified by the

manufacturer� Otherwise, degradation of the performance of this equipment could

result which could lead to patient injury�

CAUTIONS

1� Only use the endoscope with medical electrical equipment that complies with

IEC60601, and any applicable collateral and/or particular standards� Failure to do

somay lead to equipment damage�

2� Prior to using any HF endotherapy accessory, check the compatibility with the

endoscope� Always follow the IFU of the third-party device� Failure to do so may lead

to equipment damage�

3� Do not activate energised endotherapy accessories before the distal end of the

endotherapy accessory is in the field of view and is extended at an appropriate distance

from the distal tip of the endoscope as this may result in endoscope damage�

4� Do not apply oil-based lubrication in the working channel as this may increase friction

when inserting endotherapy accessories�

5� Do not coil the insertion tube or umbilical cord to a diameter of less than 20 cm (8'') as

this may damage the endoscope�

6� Do not drop, bump, bend, twist or pull any portion of the endoscope with excessive

force as the endoscope may get damaged leading to failure in functionality�

7� Do not use excessive force to advance an endotherapy accessory through the working

opatření související s obsluhou endoskopu Ambu® aScope™ Gastro nebo Ambu® aScope™

Gastro Large� Vezměte laskavě na vědomí, že tento návod nevysvětluje klinické postupy� Před

použitím endoskopu Ambu® aScope™ Gastro nebo Ambu® aScope™ Gastro Large je důležité,

aby jeho obsluha byla náležitě proškolena v klinických endoskopických technikách a byla

obeznámena s určeným použitím, varováními, upozorněními, indikacemi a kontraindikacemi

uvedenými v tomto návodu� Na endoskop Ambu® aScope™ Gastro nebo Ambu® aScope™

Gastro Large se nevztahuje žádná záruka� V tomto dokumentu je označení endoskop Ambu®

aScope™ Gastro a Ambu® aScope™ Gastro Large použito v souvislosti s pokyny týkajícími se

výlučně endoskopu a pojem systém je častěji použit v souvislosti s informacemi týkajícími se

endoskopu Ambu® aScope™ Gastro nebo Ambu® aScope™ Gastro Large v kombinaci s

kompatibilní zobrazovací jednotkou Ambu® aBox™ 2 a příslušenstvím� Tento návod může být

aktualizován bez předchozího oznámení� Kopie aktuální verze je k dispozici na vyžádání�

Pojem endoskop v tomto dokumentu označuje endoskop Ambu® aScope™ Gastro a Ambu® aScope™

Gastro Large a pojem zobrazovací jednotka označuje zobrazovací jednotku Ambu® aBox™ 2.

1.1. Určené použití

Endoskop je sterilní jednorázový flexibilní gastroskop, který je určen k použití k endoskopickému

přístupu do a vyšetření horní části gastrointestinálního traktu� Jeho účelem je umožnit

vizualizaci prostřednictvím kompatibilní zobrazovací jednotky Ambu a je určen k použití s

endoterapeutickým příslušenstvím a dalšími pomocnými zařízeními�

1.2. Určená populace pacientů

Endoskop je určen k použití u dospělých, tj� pacientů starších 18 let� Používá se u pacientů s

indikacemi souvisejícími s horní částí gastrointestinálního traktu, kdy je žádoucí její vizualizace

anebo vyšetření pomocí flexibilní gastroskopie a za použití endoterapeutického příslušenství

anebo vybavení�

1.3. Kontraindikace

Žádné kontraindikace nejsou známy�

1.4. Klinické přínosy

Při použití s kompatibilní zobrazovací jednotkou umožňuje endoskop vizualizaci či vyšetření

klíčových anatomických struktur a endoskopickou intervenci v horní části gastrointestinálního

traktu, zejména pak jícnu, gastroezofageální junkce, žaludku, pyloru, bulbu duodena a sestupné

části duodena� Zobrazovací technologie s vysokým rozlišením dovolují endoskopistům prohlížet

mukozální a vaskulární struktury� Nebezpečí křížové kontaminace pacienta ve spojitosti s

endoskopií je ve srovnání s opakovaně použitelnými endoskopy eliminováno, jelikož endoskop je

sterilní zdravotnický prostředek pro jedno použití�

1.5. Varování a upozornění

VAROVÁNÍ

1� Pouze pro jednorázové použití� Endoskop nepoužívejte opakovaně, neobnovujte ani

nesterilizujte, jelikož tyto postupy na něm mohou zanechávat škodlivá rezidua anebo

zapříčinit jeho poruchu� Opakované použití endoskopu může způsobit křížovou

kontaminaci, jež může případně vést k infekcím�

2� Ověřte, že otvor insuflačního/oplachovacího ventilu není zablokovaný nebo zakrytý a

že insuflační tlak nepřekračuje daný limit� Dochází-li k nadměrné insuflaci plynu do těla

pacienta, může mu to způsobit bolest, krvácení, perforaci anebo plynovou embolii�

3� Před použitím vždy proveďte kontrolu a zkoušku funkčnosti podle pokynů uvedených

v oddílech 3�1 a 3�4� Endoskop nepoužívejte v případě, že je prostředek nebo jeho obal

jakýmkoli způsobem poškozen anebo neprošel úspěšně zkouškou funkčnosti, neboť by

to mohlo mít za následek poranění či infekci pacienta�
