ATMOS S 351 NATAL
Special suction device
for vacuum extraction
ATMOS S 351 NATAL
Powerful universal suction device for gynecology and obstetrics
A prolonged second stage of labour, maternal exhaustion, or a health risk to the baby are situations in which a vacuum-assisted delivery is performed. Simple and safe handling is an absolute must. The ATMOS S 351 NATAL with its almost fully automatic vacuum extraction process fulfils the desire of many gynaecologists and obstetricians for more process safety. Unlike forceps delivery, which requires that many steps be performed and demands a great deal of care and experience to avoid injury to mother and child, the ATMOS S 351 NATAL is quick and easy to use.
Maximum safety for user, mother, and child
through sensor-monitored vacuum
Fewer user errors
thanks to easy handling
Gentle for mother and child
thanks to the gentle build-up of vacuum
- Hospital / clinic
- Gynecology practice
Greater operational safety
Preselectable vacuum parameters, time settings for vacuum build-up and vacuum release as well as two vacuum extraction modes (SEMI and AUTO) provide optimal support to the user when operating the device.
Sensor-monitored vacuum with acoustic and visual warning messages, a colour display with all relevant information as well as the hydrophobic bacterial and viral filter with filter change indicator ensure maximum safety and extremely easy handling at the same time.
Quiet in the delivery room
The microprocessor-controlled pump in the ATMOS S 351 NATAL ensures maximum performance and minimum noise. The low noise level provides a pleasant atmosphere for the expectant parents, improved user concentration, and optimal communication between users and the expectant parents.
In addition to vacuum extraction, the ATMOS S 351 NATAL can also be used for suction curettage, general surgical suction, and bronchial suction in newborns. Thanks to the microprocessor-controlled suction capacity with automatic regulation, the maximum vacuum can be set and thus limited. When the final vacuum is reached, the pump stops automatically and maintains the generated vacuum.
Large selection of matching accessories
The ATMOS Extraction Cup (Malmström) made of autoclavable stainless steel is available in three different diameters (40, 50, and 60 mm). The design of this extraction cup allows for easier and safer handling and also reduces the risk of the cup coming off during vacuum delivery. The ATMOS Cups made of medical silicone are also autoclavable and available in two sizes (50 and 60 mm). The design ensures that the extraction cup has an optimal hold on the foetal scalp. Autoclavable suction curettes in various sizes can be used for suction curettage.

The last phase of birth is very stressful for the baby. During contractions, the blood supply to the uterus and placenta is reduced, which can cause acute oxygen deprivation in the baby. At the same time, strong pressure is exerted on the baby’s head, which poses the risk of reduced blood flow to the brain. Depending on the child’s reserves, it may be able to cope with this enormous distress or it may react, for example, with changes on a CTG, such as slowing of the heart rate. In such cases, delivery can be accelerated with the help of an extraction cup.
The extraction cup or forceps can also be used if the pregnant woman is very exhausted.
Two vacuum extraction modes are available for vacuum extraction:
- SEMI: The device automatically generates a base vacuum level of −20 kPa (−200 mbar; 150 mmHg). After reaching the base vacuum level, the user can check the correct positioning of the extraction cup. After confirming (by pressing the ON button for switching on automatic vacuum build-up), the device generates the desired final vacuum within the specified unit of time. Once the final vacuum has been reached, the device informs the user audibly and visually.
- AUTO: The device automatically generates the desired final vacuum within the specified unit of time. Once the final vacuum has been reached, the device informs the user audibly and visually.
The colours indicate the device’s current status:
- Blue: vacuum is being generated or released. That means that the final vacuum has not yet been reached.
- Green: the final vacuum has been reached.
- Red: warning message or final vacuum cannot be generated (e.g. due to leakage).
The following settings can be made directly by the user in the user menu:
- Language (German, English, French, Spanish, Russian)
- Vacuum unit (kPa, mmHg, mbar)
- Vacuum extraction parameters (final vacuum, increase time, decrease time, mode)
- Display brightness
- Date and time
- Vacuum steps

A selection of reusable extraction cups made of stainless steel and medical silicone completes the product portfolio for vacuum extraction.
Special suction hose for connecting the extraction cup to the ATMOS S 351 NATAL.
Suction curettes are used to scrape out the uterus and remove the endometrium. The special suction instruments are connected to the suction hose attached to the ATMOS S 351 NATAL and thus enable the uterine mucosa to be drained directly into the secretion canister.
The ATMOS S 351 NATAL can be secured to a trolley for mobile use.
A hydrophobic bacterial and viral filter prevents the suction device from becoming contaminated and protects it against bacteria and viruses.
