forthetemporarycollectionoftheseuids.
Medical indications/
application:
For all applications where suction is needed, such as in gener-
al surgical procedures (e.g., suction of wound cavities, ab-
scesses), suction of the nasopharyngeal cavity, in endoscopy
forsuctionofsecretionorrinsinguids,andinneurosurgery.
For vacuum extraction.

1.1 Function
• TheATMOSC451isamains-operatedsurgicalsuctiondevice,thecoreofwhichisa
high-performance, maintenance-free diaphragm pump. It generates vacuum in the
suction hose and secretion canister system, which assists in suctioning and collect-
ingsecretions.Viaavacuumregulatorwithvacuumgauge,thenalvacuumand
thus the desired suction capacity can be precisely adjusted.
• Secretioncanistersofdierentsizesareavailableforsecretioncollection.The
reusablesecretioncanisterscanbeattachedtotheATMOSC451viatheDirect
Docking System. The user can connect the suction hose directly. A hydrophobic DDS
bacterialandvirallterlocatedinthecanisterlidpreventsbacteria,virusesand
liquidsfromenteringthedevice.Thislterprotectsthedeviceagainstoversuction.
The intake located in the hose connection prevents foaming in the secretion canister
andthereforeensuresalongerlterlife.
• A system trolley with extensive accessories is available for mobile use.
1.4 Intended users
May only be used by trained professionals in supervised and medical operations.
