Intended use

Product name:

ATMOS S 351 NATAL

Main function:

An electric suction pump controlled by a microprocessor generates negative pressure. Due to the controlled negative pressure, parts of the body, in particular the head of a baby, are fixed. The microprocessor allows the desired vacuum to be gently increased and decreased within the defined unit of time and enables a controlled shutdown of the pump. An additional secretion canister must be attached to allow for temporary collection of drained body fluids.

Introduction

Medical staff (among others: gynaecologists, midwives)

Intended patient group:

Generally, female patients of child-bearing age with and without restrictions; newborns.

Disease state to be diagnosed, treated or monitored:

Inapplicable

Application organ:

Natural orifices as well as openings resulting from surgical procedures (entire body)

Application time:

Short-term use on the patient (< 60 minutes)

Area of application:

The area of application is the clinical setting (among others: OT and delivery room). The device may only be used by staff who have been medically trained and instructed.

Criteria for patient selection:

Patients who benefit from vacuum extraction, a surgical procedure or bronchial suction

Indications:

• For vacuum extraction • In surgical procedures (e.g. suction curettage, suction biopsy) • For bronchial suction in newborns

Medical contraindica- Not suitable for: tions: • Continuous operation for drainage procedures in the low vacuum range (e.g. cardiothoracic or wound drainage) • Smoke evacuation • Liposuction • Emergency and rescue use Other contraindications:

Active

Sterility / specific microbial condition:

Not a sterile product

Single-use product / reprocessing:

The device and parts of the accessories are reusable. For information on reprocessing, cleaning and disinfection, please see the operating instructions.

1.4

Function

The products are mains-operated medical suction devices designed for vacuum extraction, temporary surgical suction and bronchial suction in newborns. The product is employed during vacuum extraction to fix the baby’s head with the aid of an extraction cup. In addition, suction material (among other things: secretion, blood) is temporarily collected in a collection canister and subsequently disposed of. During operation, the pump generates vacuum in the secretion canister and hoses, by means of which the extraction cup can be fixed on the baby’s head. Furthermore, secretion, blood and body fluids can be suctioned. The fluid is collected in the secretion canister. The buttons allow you to set the final vacuum and thus the suction capacity in steps. The set value can be read on the vacuum display. Once the final vacuum is reached, the pump turns off and only continues working if suction capacity falls below the final vacuum value. Two vacuum extraction modes are available for vacuum extraction: • SEMI: The device automatically generates a base volume level of −20 kPa (−200 mbar; 150 mmHg). After reaching the base volume level, the user can check the correct positioning of the extraction cup. After confirming (by pressing button 1 (ON) 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 indicates this 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 indicates this audibly and visually. After completing vacuum extraction or at any other time, the vacuum extraction mode can be stopped by pressing button 2 (OFF). The user can set the duration of the individual phases as well as the level of vacuum to be built up in the user menu.

Intended users

The device may only be used by trained and instructed medical professionals.

When disconnecting the device from the mains power supply, pull the power plug first and then the device plug.

•

Disconnect the device from the mains power supply before cleaning or disinfecting it.

•

Never touch the power plug or power cable with wet hands.

•

Never immerse the device in water or other liquids.

•

The device is not sterilisable.

•

Use the power cable only in dry surroundings. The surroundings must be non-conductive.

Preparing the device

Read the safety information in chapter „2 Notes for your safety“ on page 12 carefully before using the product. Damaged pump diaphragms due to cold temperatures during transport. 1. In case the device was transported at temperatures below −5 °C: let the device stand at room temperature for at least 6 hours before proceeding with the next steps 2. Check the device, secretion canisters, power cable, accessories and hoses for possible damage. 3. If the device is damaged: document and report the damages in transit. Send the device to ATMOS (chapter „6.3 Sending in the device“ on page 41). 4. If the device is not damaged: place the device on a safe, level surface.

3.3

Connecting to the mains power supply

1. Check whether the voltage and frequency data listed on the device correspond to the values of the mains power supply. 2. Connect the device to the mains. 3. Secure the power cable against accidental removal by using the safety clamp.

18 Setting up and starting up

3.4

Connecting the secretion canister system and hoses 1. The anti-foaming device must be placed on the fill-level sensor for strongly foaming secretion. 2. Slide the secretion canister lid with the release button pointing forward onto the secretion canister. & Make sure that the lid rim is under the bead of the secretion canister. This seals the secretion canister tightly and the desired vacuum can be built up in the secretion canister. 3. Press the locking handle downwards until it clicks into place. 4. Hang the secretion canister in the left or right support for the canister system. Using the support for the canister system for purposes other than what it was designed for can cause malfunctions. 1. Push the double hose connector into the canister lid twisting gently. »

The double hose connector locks into place.

1. Connect a short hose to the pipe connection on the device and to the bacterial filter. 2. Connect a longer hose to the printed side of the bacterial filter and to the vertical fitting of the double hose connector. Never operate the device without a bacterial filter. 1

3

1. Connect the suction hose (Ø 10 mm) to the angled fitting (2) of the double hose connector. & Use a hose reducer (3) for suction hoses with a Ø of 6 mm. 2. Use the vacuum extraction suction hose to join the horizontal fitting (1) of the double hose connector with the extraction cup.
