No connecting hose thanks to the ATMOS Direct Docking System (DDS)

The ATMOS DDS secretion canister system eliminates guesswork and errors. The secretion canister is attached directly to the bronchial suction device without any additional hoses.

Safe vacuum adjustment

The easy and infinitely variable vacuum adjustment of the bronchial suction devices in the ATMOS C series allows them to be used flexibly.

Suction capacity suited to every patient

With an infinitely variable suction range of 0 to −800 mbar and various suction capacities (16 l/min, 22 l/min, or 26 l/min), these suction devices can be used for any bronchial suction application and meet all requirements.

Safe for mobile use

The integrated battery enables mobile use for up to 60 minutes. It is always possible to suction the airways while the battery is charging.

How often does the DDS bacterial and viral filter have to be replaced?

The DDS bacterial and viral filter is a single-patient product. That means that the bacterial and viral filter must be replaced when the device is changed to another patient. When the device is being used for the same patient, the DDS bacterial and viral filter has to be replaced every 14 days. Should the filter become contaminated or clogged with secretion, it must be replaced immediately.

How loud are the devices?

People perceive sounds at a sound level of 40 dB to about 65 dB as soft, normal, and comfortable. It becomes loud for us starting at a sound level of about 80 dB. The maximum sound level of 56 dB of these ATMOS Bronchial Suction Devices is comparable to that of normal conversation or a TV at a normal volume level.

How long can I use the devices?

The bronchial suction devices are intended for short term operation, which for mains-dependent devices means 5 minutes on and 20 minutes off. The battery-operated devices can be used for 10 minutes and must then be turned off for 30 minutes.

Is there a carrying bag for these devices?

A carrying bag (REF 313.0011.0) is available for fixating and storing these devices. In addition, you can store accessories and consumables such as the DDS bacterial and viral filter or suction catheters in the bag’s useful storage compartments.

Can the devices be secured to a wheelchair or bed?

Yes. You can secure the devices to standard rails, stands, patient beds, wheelchairs, etc., by using a device support (REF 313.0012.0).

Can the ATMOS C 161 Battery be taken along in a plane with no problems?

The ATMOS C 161 Battery can be taken along on plane trips in checked or carry-on baggage without difficulty. It is possible to operate the device during a flight. Individual instructions from the flight crew and airline-specific regulations must still be followed.
